On most installations of Windows 10 the 1607 update installs without a problem. It just happens to be that my laptop is not most installations. For one, I am using deduplication which is a server feature not to mention all my developer tools.

After installation, my deduplication stopped working which I fixed with new 14939 packages and none of my store apps worked. I fact my store didn’t even open.

Error “This app can’t open”

Managed to fix store by running wsreset.exe after which I could repair all my apps

Had an interesting issue. Our installation of SNMP service kept failing.

The same error was shown when using PowerShell, DISM and Server manager.

Long story short, weirdly the installation is only deemed successful if the service can start, if it cannot, the whole installation is rolled back.

In our case a 3rd party app was hogging UDP 161 and SNMP failed to start hence the installation kept rolling back.

The culprit was identified by looking for the process that uses UDP 161 in output of command “NETSTAT -anb”

After killing this process installation work

Just some issues I experienced using WCF-SQL…

Error: Value cannot be null

Solution: Specify a SOAP Action Header. This can also be found in the XSD of the generated metadata

---

 

Error: Received unexpected message type, does not match expected type

Solution: Change the receive pipeline to XMLReceive

1. Create two Orchestration messages of same type. In this case I refer to them as Message1 and Message2
2. Create a Orchestration variable of type System.Xml.Document. Tn this case I refer to it as xmlDocument
3. Construct Message1 outside, before the loop with a Transform ect.
4. Inside loop, within a single Construct Shape:
   1. Assign xmlDocument to Message2
   2. Manipilate Message2
   3. Assign Message2 to xmlDocument
5. Outside, after the loop, assign xmlDocument to Message1
6. Return Message1

1. Create an Orchestration string variable (in this case testVAR)
2. Add assignment shape with code below
3. Change the send location output file name to %SourceFileName%

   [sourcecode language=”csharp”]
   outputMessage = outputMessage ;

   testVAR = xpath(outputMessage,"string(/*[local-name()=’SomeName1′ and namespace-uri()=’SomeSchema’]/*[local-name()=’SomeName2′ and namespace-uri()=”]/*[local-name()=’SomeName3′ and namespace-uri()=”]/text())");

   outputMessage(FILE.ReceivedFileName) = testVAR + ".TXT";
   [/sourcecode]

    

Add the following function

[sourcecode language="javascript"]

    function getParameterByName(name) {

        name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");

        var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),

            results = regex.exec(location.search);

        return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));

    }
[/sourcecode]
Then you can use this to get ClientContext

[sourcecode language="javascript"]

    siteUrl = getParameterByName("SPAppWebUrl");
    var clientContext = new SP.ClientContext(siteUrl);

[/sourcecode]
	

Yeah, I missed this. Maybe you did too…

When you press Windows key + Print Screen it takes a screenshot and saves it into folder call Screenshots under the My Pictures folder. Super convenient

Problem: I have a flat file with optional records for which I need to create a schema. Validation of schema only succeeds when a file is selected that contains all the possible records and fails if any is removed.

Resolution: Change the Parser Optimization (located on the schema node) to “Complexity” instead of “Speed” optimization.
