• Software Development for Windows Vista How to use the cancel handler?

  I have two workflows A and B. In workflow A I have the instance Id of workflow B. How do I gracefully cancel workflow B from workflow A Is this where the cancel handler should be invoked How When the cancel handler completes does the workflow exit Thanks. Workflows cannot perform instance operations on other workflows, only the host can do that. What you can do is make a request to the host from one workflow instance to terminate/suspend/unload/etc. another workflow instance. The CancelHandler is something completely different. This is used to store cleanup logic for activities that are canceled during e ...Show All

• Visual Studio Debugging your packages.

  The solution built by the Guidance Package toolkit doesn't let you debug your package easily. First, check out my other post about "Making buiding faster". If you do what I say in that post, you will have the single package project in your solution. If you don't then you have to make just make the package project the Startup Project. Make sure your in "Debug" not "Release" mode. Go to Properties and pick the Debug tab on the left. Change the Start Action to "Start external program" and enter in the path to your devenv.exe. Mine is:    C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe Now put some breakpoints in ...Show All

• .NET Development Help debugging bad web services call

  I'm fairly new to the web services side of .NET.  I've inherited some code I'm trying to get to work.  It was only partially implemented and the original programmers are gone. Sorry if I don't have all the terminology right.  Basically I'm making a function call from regular code to a web service function (Validate(string s, ...)).  There is a "Web References" folder that's been created, and a References.cs file that has been automatically generated.  I debug and trace up to the point of the Validate(string s,...) call.  At this point s has valid information (valid reference, valid string data), according to the ...Show All

• .NET Development How to send custom made datagram packets in C#

  The requirement is to sent custom made datagram packets using TCP to custom made ftp server. The datagram should have custom header field such as version,type,payload length(custom fields). It should also have a custom payload portion. Any idea how to create this custom packet and send it over tcp Regards, Hema. Sending a custom payload in the body of a TCP packet is pretty simple with the System.Net namespace. The classes you will want to look at are: TCPClient or Socket. We also have an FTP implementation, but it does not allow custom FTP commands to be sent. For Socket code exam ...Show All

• SQL Server Huge issue with the Lookup problem

  Hi, I have Script Component in the Transformation phase that returns me values like NO, OTH, OWN (comma separated string coded value) Now I want to use the Lookup component (preferably or any other task really) to get the description by looking up a table in another database. So eventually my string needs to look something like this None, Other, Owned (comma separated string decoded value) I tried using the Script component again to do this, but failed miserably. I am having such a hard time connecting to another database within the VB.NET script designer. When I tried using the Lookup task, I ONLY end up getting the first value returned. So ...Show All

• Visual Studio Express Editions Next page - HasMorePages

  Hi, I fill my printdocument with handly positions. Page 1 works correct. But it doesn't go to page 2. Dim intHoogte As Integer = 120 while (blablabla) If intHoogte Mod 73 = 0 Then ev.HasMorePages = True intHoogte = 120 End If intHoogte += 15 End While After this code, the text for page 2 appears on height 120 on page 1. Guessing a bit here. I assume this code is inside a PrintPage event handler and that you use intHoogte to track how much you've printed sofar, generating a new page when you've output 73 lines of text. Make sure you exit the event handler after yo ...Show All
