• Visual Basic WMI impersonation and an exclamation mark!

  I've seen many example scripts with lines such as: GetObject("winmgmts:"{impersonationLevel=impersonate}\\"...... cut I have also seen many with an exclamation mark after the impersonation part: GetObject("winmgmts:"{impersonationLevel=impersonate} ! \\" but I can't find out what this means, can anyone explain It's beginning to make sense now, that's been very useful Cathal. I can do some testing based on what you've said. This whole subject of monikers isn't covered too well - I need to spend a bit of time in the bookshop.

• .NET Development Creating ASP.Net WebUserControl at RunTime and saving as a new .ascx file using CodeDom

  Can anyone please throw some light on creating ASP.Net WebUserControl at RunTime and saving as a new .ascx file using CodeDom Thanks in advance. Hi! That's a fantastic question! First off, you should be able to create the web user control in code by declaring a new instance of a webuser control, and then dynamically adding your controls to it, just like you would if you were adding controls to an existing page, or what have you. Saving it is the part that I'm not sure about. Try posting in the ASP.NET forums and someone over there should have a better idea. The best place for asking ASP.NET questions is on the ASP.NET commun ...Show All

• SQL Server CREATE ASSEMBLY failed because method 'get_Count'...

• Visual C++ Image Color Management in VC++ 8 Platform SDK

  I'm converting a VC++ 6 MFC app to VC++ 8 using Visual Studio 2005 Standard. The existing app uses Image Color Management, so it #include's icm.h. In the VC++ 6 environment, it is included from the Platform SDK [$(ProgramFiles)Microsoft SDK\include] directory. A Visual Studio .Net installation delivers a version of the Platform SDK in a subdirectory of the VC directory [$(VCInstallDir)PlatformSDK] and this directory is setup to be used for includes upon install. However, icm.h is not included in this version of the Platform SDK delivered with Visual Studio 2005. The file does exist in both VS2002 and VS2003 installations. Was this ommi ...Show All

• Visual Basic Will the next framework release have code for decompressing zip files

• Visual Studio IVsProject3->OpenItem is called for each document having a breakpoint before the debugging starts

  Hi, I have implemented my own debug engine, we are creating a virtual project to enable debugging. All my docs are non file based docs. My problem is that when I start a debugging session I see that OpenItem in IVsProject3 is called for each document that has a breakpoint in it. Iam not sure why it is happening but I observed the same behavior with the MY C sample provided with the sdk. The call comes from the Vsdebug.dll, Is there any way by which I can stop these calls coming as these calls are unnecessarily trying to open documents that may or may not be required, I would still like my breakpoints to be available as otherwise I wou ...Show All

• Visual C# Another event handling question

• Software Development for Windows Vista Dynamically changing rules definitions in .rules file without recompiling the WF

  Hi, I have developed a sample application for validating credit cards and as a part of implementation, i have used policy activity and defined some sample validation rules using rules editor. I expect my end user to edit these rules with valid actual rules and my WF has to execcute its policy activity against these newly created validation rules. Please suggest me a workaround to implement this scenario. Please note that, i don't want to use DB support for this as my implementation will be deployed as a class library and i want my WF goes along with the dll. So i'll prefer using .rules file.

  Hi There I realize these question are not specifically for replication by anyway .... I am using snapshot replication from Server 1 to Server 2. I cannot use the drop table option for replication publication. The distribution agent keeps on failing if a colmn order is different or an index defined differently. Is there any script or sp i can run to check that table defintion, column order, idexes etc are identical between servers Also when the distribution agent fails, is there anyway to start from where it left off applying the snapshot instead of starting right from the beginning My main concern for not dropping the tables is loosing al ...Show All
