I'm trying to create a simple workflow for a SharePoint add-in using Visual Studio 2015. The attached MS Word document shows the design. The workflow is supposed to add an item to the list Deviations automatically when an item is added to the list DevInfo manually. Based on the DevInfo list, WorkflowHistoryList, and WorkflowTaskList (see screenshots in the attached), it appears the workflow does not fire at all.

I noticed the workflow.xaml file is not automatically added to a feature, although WorkflowHistoryList and WorkflowTaskList are. Is that something I need to add manually?

Also if I try to open the workflow after deploying the app on a dev site, I get an error and have to close/reopen the project. See screenshot in the attached.
I'm using Visual Studio 2017 and I'm looking for a tool/extension/utility that can add exception handlers to my code. I've been using MZ Tools, but it recently started to crash VS every time I try to do that. I've uninstalled/reinstalled both VS and MZ-Tools, contacted the creator of MZ Tools, but no joy so far.

Any suggestions?
I have a vb.net Windows Forms application compiled in Visual Studio 2013 using .NET 4.0 (not client profile), x86 target cpu.  The application has been running on multiple machines across dozens of networks for several years.  Suddenly a couple of weeks ago it stopped running on 64 bit machines on 1 network. 32 bit machines still run it from the same server. 64 bit machines are running .NET 4.6. Windows updates were rolled back, firewalls turned off, running as administrator, anti virus turned off, user network permissions are good. Any tips would be greatly appreciated.

I just upgraded to TFS 2017 and deployed an agent and created a new build. I am getting the following error when building:

No agent found in pool Default which satisfies the specified demands:

I have tried install Visual Studio 2017 Pro, updating the agent, installing build tools, restarting the Agent service, restarting the service, unregistered and registered the Agent. None of these steps have helped.

We moved a asp.net project from Visual Studio 2013 to Visual Studio 2017. The issue is that when you make changes to the JavaScript file, the changes are not effected on the min file. Also, when you checkout JavaScript file for edit, the min and map files are not checked out. We are using VSS for code control. How do we fix this issue?

Open in new window

before this error, i got another error,
which i fixed by following this article

I'm not sure if they are connected

I've followed some other articles which has a microsoft hotfix, but i think it applies to an old version of visual studio as i get an error when running "not applicable for you" or words to that affect

There is a hack to write gatherallfiles=true in project config, but that basically published all the aspx and aspx.cs files, which i cannot have

Does anyone have inner knowledge of this? I spent 7 hours going through all the various examples online, so chances are if you just put the above into google, i've already tried it.
Just switched to a new computer and WebMatrix is not available any longer so I am playing around with this product.  How do I get my pages and changes to the server?

I am setting up a build definition on my MS Team Service in the cloud that includes a unit test. The unit test actually makes a database call to our test database.  I am using Visual Studio Build, copy files, Visual Studio Test Tasks. I am confused as to how to set up a connection to my test database which s not on the cloud but on an in-house virtual server. Any suggestions will be welcome.

Hi all of you ^^. I am building a browser. But i am got stuck when i attach a splash screen to an event in my browser.
Link: Project Simple Browser
After open my sln file. you will see that my project have 2 part.
part 1 is main project (Form1)
part 2 is a splash screen (StartFormSplash)

b, On Form1.cs line 52-57 you will see
private void geckoWebBrowser1_DocumentCompleted(object sender, Gecko.Events.GeckoDocumentCompletedEventArgs e)
            // CSS Logo google
            GeckoHtmlElement logo = geckoWebBrowser1.Document.GetHtmlElementById("hplogo");
            logo.SetAttribute("style", "display:none");

Now debug, you will see with code above
logo has been removed after 1 seconds google webpage have completed loaded // we focus on this thing //
Because code running on DocumentCompleted_Event only excute when a webpage load completed

c, I need your help to use a Splash Screen when DocumentCompleted_event code has not been finished/running.
-> i dont want see google logo in my browser a bit.

Thank all of you (Y)!!!
i want to do indirect addressing rather than using indexed addressing by using visual studio 2010.
this code i want to do it

source BYTE "This is the source string",0
target BYTE SIZEOF source DUP(0)
mov esi,0 ; index register
mov ecx,SIZEOF source ; loop counter
mov al,source[esi] ; get char from source
mov target[esi],al ; store it in the target
inc esi ; move to next character
loop L1 ; repeat for entire string
Hi All,

I create windows app.

I try below :

   oSheet.getCellByPosition(ColTitle.Debet, intRow).NumberFormat = mdlOpenOffice.getNumberFormat(oCalcDoc, strNumberFormatDecimal)

  Public Function getNumberFormat(ByVal iDoc As Object, _
                                    ByVal iFormat As String) As Integer

        Dim nFormatId As Integer = 0

        Dim sCharLocale As Object = iDoc.getPropertyValue("CharLocale")

        iFormat = Set_Format_Number(iDoc, iFormat)

        nFormatId = iDoc.getNumberFormats.queryKey(iFormat, sCharLocale, False)

        If nFormatId = -1 Then 'Not yet defined
            nFormatId = iDoc.getNumberFormats.addNew(iFormat, sCharLocale)
        End If

        If ERV_Global.Get_Decimal_Char() = "," Then
            nFormatId = 5004
            nFormatId = 5003
        End If

        Return nFormatId

    End Function

  Public Shared Function Get_Decimal_Char() As String
        Dim curNilai As Decimal
        curNilai = 1.5

        Get_Decimal_Char = Format(curNilai, "#.0")
        Get_Decimal_Char = Mid(Get_Decimal_Char, 2, 1)
    End Function

It just not formatting, just plain number.

What's wrong ?

Thank you.
Background: i work in a red hat and Windows 10 environment. We have models written in Matlab and Simulink that the developers will convert to C++ in order to get higher speed simulations. We do not like the C++ code that can be generated from these two products. We have a simulation proprietary framework which provides us with many math APIs for C++.

We currently use C++03 with Visual Studio 2010 and g++. Lead developer has no experience with C++11 but he would like to convince a large community of divisions to upgrade to C++11 . I asked him what skill levels of developers would he be bringing in . He said his group cannot afford the best, and he believes that C++ 11 is more complicated than C++ 03. Recently I've been doing this survey of multithreading capabilities in C++11, boost, Pthreads, WIN APIs , and while I can see that C++11 features are rich , they are also complicated to use correctly . For example if you want to squeeze performance out of a program that uses many cores , then you have to learn about the C++11 memory model, and be aware of all the tricky race conditions that can occur when the high-level code is done out of order as result of compiler optimization .

 Could someone give me a list of C++11 features that an average C++ developer could use and explain how it is beneficial with a strong argument that we convince a large community of divisions to agree to upgrade to C++11 .

 Two items that come to mind are multithreading and dimensional …
Thank you fo spending time read my post!

Please help. I got stuck it a month :( :( :(
I have a large (14 000 lines) aspx file, every time I click, type or save my visual studio 2017 completely freezes for a few seconds.

I have looked on google and can't seem to find an answer.
All extensions have been disabled.
All code analysis tools have been disabled.

I have then used Process Monitor to investigate and I can see devenv.exe hammering my computer with "NAME NOT FOUND" for both files, folders and registry entries. I am not sure what it is trying to find, but its not succeeding.

Is there anything I am missing? Maybe a feature somewhere I can disable?

Attached the procmon output.
