• Windows Forms TopMost window only to a certain window handle

  Setting the TopMost property makes the window top of all window handles. How do I make the window topmost only for a particular window handle not all.

• Visual C# Determine current WinXP user profile by reading the registry with C#

  Hi C Sharpers, I'm developing a WinForm app that needs to determine the current user of the system (Win2000, WinXP) and send that profile's information to the server. The best way so far is to read into the system registry and retrieve it. How can I securely do this in C# In my application, there is also supposed to be an added feature that allow users to change their username and password. I understand this has something to do with ...Show All

We ran into a problem when the state machine is in its end state. We can access the instance of the running workflow,  is there a way to determine whether the instance is in its endstate Thanks in advance. Ronald When a state ...Show All

• Visual Studio VSS 2005 WebService problem

  Hi hi. I'm trying to use the new WebServices in VSS2005. After fiddling around, reading through the forums and doing some more fiddling I've just given up. The problem is authentication. I can open the share from my computer, open the project from the share (with the non-internet version of the VSS plugin) and open the webservice url from my computer. I've tried doing SSL, but the result is the same. If I directly open a project under source con ...Show All

• Software Development for Windows Vista Cannot add workflow into folder

  When I create a folder under a project , and try to add the flow under it, if I click "add-->sequential workflow",VS2005 always add the item under the project root and namespace doesn't contain the folder name. But if I go thru another path "add-->new item-->sequential workflow", then it works fine. I don't see it is a big issue, but it's definitely a bug. Hope some Microsoft developer can see this post and fix it in the final r ...Show All

• Software Development for Windows Vista Custom Composite Activities and Correlation Tokens

  Beta 2.2 Perhaps a tricky one for the WF people: I have a custom SequenceActivity that has some logic for generating the properties I need for a CallExternalMethodActivity and HandleExternalMethodActivity. The general idea is that the composite activity encapsulates the supporting logic for a user input custom activity. Now, for each type of typed input from the user, I inherit from this class and put the actual CallExternal and HandleExternal a ...Show All

• Visual C++ Platform SDK help files

  I downloaded and install the latest Platform SDK, and compiled a sample, it works fine. (under Visual C++ 6) Now I'd like to visit the Help files to get more information about the APIs and other useful information. However I don't know have how to view / open these help files (Help 2). After a desperate huge search over the Internet, I rely on this forum to get some help. Thank you. I had the same problem ...Show All

• .NET Development Delayed send with smtpclient in .net 2.0

  Is there any way to force the smtpclient to send mail immediately with the .send method in system.net.mail 2.0 Right now it takes anywhere from 90 secods to two minutes before the mail is actually sent once the .send method executes. I've tried setting the object to nothing immediately after the .send method call, but no luck. The real issue for me is the send delay is also causing the smtpclient  to hold a lock on attached files that are ...Show All

• .NET Development Problem with RijndaelManaged and PaddingMode; PaddingMode seems to be ignored.

  In the July 2005 CTP .NET Framework 2.0 bits, I've found that the PaddingMode property seems to be ignored, and PaddingMode.Zeros behavior is always used instead. This is a serious problem--because with PaddingMode.Zeros you don't get guaranteed "reversibility" during decryption--you won't know for sure what's padding and what's the actual decrypted data. I've posted a bug on this on labs.msdn: Padding / PaddingMode Property IGNORED in Rijndael ...Show All
