Install-WindowsFeature Web-Net-Ext failed. Source files could not be found.

Error:

Trying to install .NET Framework 3.5 Features on a Windows Server 2016, either through GUI or PowerShell, returns below error (truncated):

“The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed.
The source files could not be found.”

Cause:

.Net Framework 3.5 sources file are not pre-installed so we need to explicitly specify where “installer” can get the source files from.

Solution:

As per Microsoft’s official docs, there are 2 main solutions to make it work.

  1. Through GUI (Server Manager), when asked during the wizard, you need to specify the path to “Media:\Sources\SxS” folder.
  2. Through PowerShell, Install-WindowsFeature -Name Web-Net-Ext -source D:\Sources\SxS

Still, Microsoft says that even if this defined source is not found, installer should go to Windows Update to download required files. Let’s exclude those many possibilities that Windows Update is not accessible due to various reasons (no internet connection, GPOs disabling something etc.).

Anyway, since neither one of the above methods worked for me, I kept reading posts from 2nd+ google pages. This led me to not-so-old post from Michael Niehaus: https://blogs.technet.microsoft.com/mniehaus/2015/08/31/adding-features-including-net-3-5-to-windows-10/

Not sure what’s different with calling DISM directly (since Server Manager and Powershell probably does the same), but below solution worked for me.

Run this from PowerShell (including tilde characters): DISM.exe /Online /Add-Capability /CapabilityName:NetFx3~~~~ /Source:D:\Sources\SxS where D was the drive with my mounted Server 2016 ISO.

When above command is done, run this: Add-WindowsCapability –Online -Name NetFx3~~~~ –Source D:\Sources\SxS

What and when: DateAdd vs ParallelPeriod vs SamePeriodLastYear

Reza Rad over at http://radacad.com/dateadd-vs-parallelperiod-vs-sameperiodlastyear-dax-time-intelligence-question explains the differences and provides easy usage scenarios for DateAdd, ParallelPeriod and SamePeriodLastYear DAX functions.

Read his blog post to see how he reached to below conclusion:

  • DateAdd and SamePeriodLastYear both work based on the DYNAMIC period in the filter context.
  • ParallelPeriod is working STATICALLY based on the interval selected in the parameter.
  • ParallelPeriod and DateAdd can go more than one interval back and forward, while SamePeriodLastYear only goes one year back.
  • DateAdd works on the interval of DAY, as well as month, quarter and year, but ParallelPeriod only works on month, quarter, and year.
  • Depends on the filter context you may get a different result from these functions. If you get the same result in a year level context, it doesn’t mean that all these functions are the same! Look more into the detailed context.

Power BI: The key didn’t match any rows in the table

Error:

Refreshing Power BI report generates “The key didn’t match any rows in the table” error.

Cause:

Click “Edit Queries” button. If you do not see the error message, click “Refresh Preview” button. Once you have the error message, click “Go To Error“.

Error message will remain, but you should have “Edit Settings” button now, click it.

In the next screen, Navigation, you should see what exactly Power BI is trying to access but cannot do so.

In my example, I have an Excel file as my source. When I first connected to this data source, my Table name was Table1. Yesterday I changed where my Excel file gets data from and this, in turn, changed Excel’s Table name to “report“.

Obviously, when Power BI tries to refresh the data, it cannot find Table1 table anymore.

Solution:

In the same Navigation screen, selecting my new Table name “report” will fix the issue assuming all other columns in the Excel file are the same.

Same is true for any data source, not only Excel file. Follow same steps to identify what’s causing the error and then fix it as needed.

Expressions that yield variant data-type cannot be used to define calculated columns.

Error:

Expressions that yield variant data-type cannot be used to define calculated columns.

Cause:

IF based Calculated Columns in Power BI or Power Pivot with 2 different data types is not allowed.

Solution:

Format one data type as needed using FORMAT() function.


Age = IF (
TableName[Birthday] < TODAY(),
FORMAT (
Year ( TODAY() )- Year ( TableName[Birthday] ),"General Number" ),
"Invalid birth date"
)

FORMAT Function (DAX): https://msdn.microsoft.com/en-us/query-bi/dax/format-function-dax

Creating an e-book. Part 3.

Continuing the series about how to create an e-book. Today we’ll have a much shorter post. Specifically, we’ll look at how to create the Title page.

So, what is a Title Page? According to dictionary.com, Title Page is: “the page at the beginning of a volume that indicates the title, author’s or editor’s name, and the publication information, usually the publisher and the place and date of publication.”

If you’ll search Google Images for “title page”, you see lots of examples of how a Title Page looks like. And, it seems to be the easiest to create. Technically speaking, a bunch of paragraphs and that’s it.

Ok, following dictionary.com’s description, let’s create our Title Page. We will need the following:

  • Book title: I will use “My Book’s Title”
  • Author name: this is simple, “Vitalie Ciobanu”
  • Publisher info: I do not have one so I will use “Lorem Ipsum Publishing Inc.”
  • Place and date of publication: “Madagascar 2018”. I still want to visit this island…

Open mybook.html page in Notepad and add above details right before your first chapter (which should be <h2> tag); each detail on different row and inside a paragraph element (<p></p>). Here is my <body> element now (trimmed):

<body>My Book's Title

Vitalie Ciobanu

Lorem Ipsum Publishing. All rights reserved.

Madagascar 2018
<h2>Lorem Ipsum</h2>
<h3>What is Lorem Ipsum?</h3>
<p class="first">Lorem ipsum dolor sit….</p>
<p class="quote">Nullam tortor orci…..</p>

Curabitur ligula tortor, ullamcorper….

</body>

And here’s my page viewed in a browser:

Because we have p selector defined in our stylesheet file, you see above we have some formatting applied already. Let’s add additional selectors to the stylesheet to make Title page information differently looking. So, let’s add some different formatting for book title, author, publisher and date of publication. Here’s just some basic CSS added to my epub.css file:

p.booktitle {
    text-indent:0em;
    text-align:center;
    margin-top:5em;
    font-weight:bold;
    font-size:150%;
}

p.bookauthor {
    text-indent:0em;
    text-align:center;
    margin-top:1em;
    font-weight:bold;
    font-size:130%;
}

p.bookpublisher {
    text-indent:0em;
    text-align:center;
    margin-top:3em;
    font-weight:bold;
    font-size:100%;
}

p.bookpublished {
    text-indent:0em;
    text-align:center;
    margin-top:1em;
    font-weight:bold;
    font-size:100%;
}

For each selector I wanted no indentation so I added “text-indent:0em”. Also, everything is centered and bold. Font size is different, with Book Title being the biggest one, 150%em. Lastly, I added different top margins to visibly separate each line. Afterwards, I updated the class details on my newly added paragraphs in html file.

<body>
<p class="booktitle">My Book's Title</p>
<p class="bookauthor">Vitalie Ciobanu</p>
<p class="bookpublisher">Lorem Ipsum Publishing. All rights reserved.</p>
<p class="bookpublished">Madagascar 2018</p>

<h2>Lorem Ipsum</h2>
<h3>What is Lorem Ipsum?</h3>
<p class="first">Lorem ipsum dolor sit….</p>
<p class="quote">Nullam tortor orci…..</p>

Curabitur ligula tortor, ullamcorper….

</body>

How to automatically create and update Visio diagrams from Excel

To successfully create Visio diagrams from Excel, Visio Pro for Office 365 is required. Here you can see the prices or download trial.

  1. Open Excel (I have latest release of Excel from Office 365 suite)
  2. In the search box, type “process” and hit Enter. Among other search results, 2 Excel templates should appear with Excel icons in upper left corner and Visio diagrams in lower right corner. Select the one you want/need. I will continue with Process Map for Cross-Functional Flowchart.

  3. A nicely formatted Excel file will open with pretty much all info you need to know about Data Visualizer; the solution that allows us to create diagrams from Excel.

  4. Head over to Process Map worksheet.
  5. You’ll notice here we have “ProcessMapDataTable populated with 2 rows. This is the Excel Table that we need to work with. Everything else can be deleted/ignored.

  6. Remove the 2 rows added as examples and add your process’ field mappings. For this example, I will use Software Development process found on www.smartdraw.com
  7. I will modify my Excel Table based on this process. Here is my final Table:
Process Step ID Process Step Description Next Step ID Connector Label Shape Type Function Phase
P01 Start P02 Start Project Management Planning
P02 Gather requirements P03 Document Project Management Planning
P03 Develop specifications P04 Process Software Design Design
P04 Develop internal design P05 Process Software Design Design
P05 Develop external design P06 Process Software Design Design
P06 Change required? P05,P07 Yes,No Decision Software Design Design
P07 Define Development team P08 Subprocess Software Development Coding
P08 Application development P09 Process Software Development Coding
P09 User Acceptance Testing P10 Process Software Development Coding
P10 Quality Assurance P11 Process Software Development Coding
P11 Defects P08,P12 Yes,No Decision Software Development Coding
P12 Release to production P13 Subprocess Release Management Release
P13 Stop End Project Management Release

Make sure that you have more than one value in Next Step ID, you should have similar number of values/labels in Connector Label column and that those values match its corresponding step.

For example, P06 Step ID is a decision point. If changes are required (Yes), process goes back to P05 Step ID. If no changes are required (No), process proceeds to P07 Step ID.

Lastly, ensure your last process step has nothing in Next Step ID field, because it’s the last one, there is nothing else afterwards… process ends here. Save your Excel file.

  1. Open Visio.
  2. In the search box, type “data visualizer” and hit Enter. You should get the Basic and Cross-Functional templates. Select the same one you used for creating the Excel file. Cross-Functional Flowchart in my example.

    Just in case you started it wrongly or you want to get Excel template again, click Excel data template. Select your local Unit and click Create.

  3. Visio will open Create Diagram from Data wizard.
  4. Using first drop-down box, select the correct diagram type to use.
  5. In the second field, browse to the Excel file you created and saved in Step 7.
  6. In the last field, Visio should automatically recognize your Excel Table name, ProcessMapData in my example. Click Next.

  7. If you did not modified headers in the Excel Table, next page should automatically recognize and map Function and Phase columns. Expand More Options if you want to modify the order of column values. Assuming you created your process in a chronological order, you’d probably want to retain the same order in Visio.

  8. On the next wizard page the same, if you left all default column headers, Visio will automatically recognize and map needed columns. Otherwise, drag and drop the columns from the left.

    Short note here: you probably noticed your Excel Table has blue and green headers. Blue headers are required for these mappings and building your final diagram. Whether green columns are nice to have. All those columns may have valuable info for the diagram, but I think Microsoft still has ways for improvement this specific side, especially Alt Description, because it may contain too much text. Add something to this column and you will see what I’m referring to.

  9. Next page is about choosing your required Visio shapes. I did not have anything to modify or comment here. It seems like Microsoft is limiting the user to use predefined shapes but, anyway, default shapes are kind of standard so should be sufficient.

  10. The last wizard step is the one we need to modify to suit our needs. Make sure Next Step ID is selected for Specify Column Name, Relationship is set to Next Step, Delimiter is set to comma and Connector Label is mapped to its column with same name. Click Finish.

  11. You should now have a fully functional Visio diagram. Note that Visio will zoom it in such a way that it fits your page; if needed, zoom it in or out to see the details. Also, for some reason, Visio creates a lot of unused space between each shape. Feel free to rearrange everything to save space.

One nice thing about having this Excel file linked to Visio is that any updates you make to the process in Excel, you can refresh Visio diagram to update it with those changes. Just select your Visio diagram and from Data tab, in Create from Data group select Refresh.

For reading official Microsoft article about this, please take a look at “Create a Data Visualizer diagram” post. It contains more valuable info, including a description about each Excel columns that interact with Visio flowchart components.

Similarly, here’s a video made by Microsoft.

July 20, 2018: Microsoft just posted another, shorter, video on YouTube marketing same thing.

How to start Word with a specific template

  1. Open Word the usual way.
  2. In the template selection view, select the template you want and click Create. For example, Blog Post.
  3. When Word opened your document, click Save As and select Word Template in the Save as type drop-down box.

    Path should change automatically to your Custom Office Templates directory.
    Give your template a name. For example Blog, to keep it simple. At this point, you can close this document.

  4. On your Desktop or wherever you want, right click and select NewShortcut.

  5. In the location field, add full path to winword.exe file; default location for 2016 version is “C:\Program Files\Microsoft Office\root\Office16”. Also, you need to specify the location and name of your template file. Mine is in “D:\_Main Documents\Documents\Custom Office Templates” so my full path will be (including quotes and template name): “C:\Program Files\Microsoft Office\root\Office16\WINWORD.EXE” /t”D:\_Main Documents\Documents\Custom Office Templates\Blog.dotx”

    Make sure there is a space before /t switch and there is no space between the /t switch and template path. Click Next.

  6. Give your new shortcut a name; Blog from Word for example. Click Finish.

  7. Your new shortcut is now ready for use. Double click it and Word will open using your new template without asking anything else.

Optionally, it’s more a nice to have actually, you can personalize your shortcut with a custom icon so that you can quickly differentiate it from other Word files and shortcuts.

  1. Right click your new shortcut and select Properties.
  2. Click Change Icon… and browse to the location where you have an .ico (ICO file format is an image file format for Windows icons) file you want to use.

    If you do not have an icon to use, click Browse and in File name box type: %SystemRoot%\System32\SHELL32.dll
    Here you have quite a few old but good icons that you can choose from. Select one icon and click OK twice.

  3. Your shortcut is now fully customized and ready for use.

How to use Word for Blog publishing

  1. Start your Office Word application. It works with any version starting with Word 2007.
  2. While you’re in the new template selection view, search for “blog” in the “Search for online templates” field.

  1. Blog post” template should be listed. Click it and then select Create button.

  2. On first run only, you’ll be asked to register your blog in Word. You can click Register Now and walk through this process or you can click Register Later and do it later by using Manage Accounts from Blog command group.

  3. If you clicked Register Now, you’ll be asked to select your blog provider. You see that this list does not include all possible blogging platforms, that’s kind of normal I’d say…, but you have the Other option and you then can add any blog details as long as you know the link to provider’s API.

    I selected WordPress because this is what I have.

  4. Next screen will ask for your blog’s URL. And, this is different from platform to platform but, for WordPress you need to provide the link to your xmlrpc.php file. It is usually in your root folder of your site but if it is in another folder, make sure to add the correct path.

    For default location, just paste your site’s address between the backslashes, thus replacing <Enter your blog URL here> with your blog’s URL.

    Add your username and password. Optionally, select Remember Password if you’re the only one who’s using your Windows account. If there are more people using same Windows account, to prevent others posting funny things to your blog, leave this option unchecked.

    Under Picture Options, you can select where your post’s pictures will be uploaded to. For simplicity, keep it as My blog provider.

  5. Once you have all fields completed, hit OK.

  6. If everything was done correctly and Word could connect to your blog, you’ll be presented with a nice confirmation message.
  7. Next, you’ll have your Word template changed to Blog. Notice Blog command group. It contains all your basic needs for creating and publishing blog posts. One thing is missing though, ability to add Tags.

    If you have a more complex blog, photography maybe or e-commerce, or if you use Featured Images or you need to add Location to your posts, probably Word is not that much suitable to you.

  8. From Insert tab, you have access to add a lot of items to your post, like images, shapes, tables etc.. As an example, below picture has Rounded Corners style added.

Below is a shape added from Word, it will be posted as a picture:

 

Just in case something went wrong and you have issues connecting to your blog or uploading images, please take a look at Microsoft’s article about this, scroll down to the bottom for troubleshoot problems.
