• Visual C++ What's wrong here with _wfopen

  I have this code line with very strange behaviour: FILE* fp = _wfopen(( const wchar_t *)_T("c:\\Hello.txt"), ( const wchar_t *)_T("r")); Here fp pointer is always equal to null. When I debuged i found that filename was with strange symbols, not normal letters. I'm on Windows XP SP1. Please somebody help me. Any help will be greatly appreciated. Why are using the _T macro If your are using an unicode function version you should be using the L specifier and drop the conversion to wchar_t * like in:   _wfopen(L"c:\\Hello.txt", L"r");   ...Show All

• Windows Forms Accessing controls in external windows

  How do you access controls in a window that have been created by another program I have got the window handle, and want a list of all controls in the external window. I am newbee to .NET,  programming in C#. very thankful for help! Jessica4710 wrote: Given a handle, you typically can call Control.FromHandle to retrieve the Control. However this only works if you're on the same thread as the control. Since you are cross-process, this wont work. Won't even work cross-thread. You can get certain information using active accessibility. This is how we recommend folks test their applications. Mor ...Show All

• Visual Studio Lost implicit "and" search functionality in MSDN Library after installing VS 2005

  I had Visual Studio .NET 2003 and MSDN Library October 2005 installed and working just fine.  Normally, to search a topic in the MSDN Library I used to just list the words separated by spaces: e.g.  activex license deployment.  The space between the words used to function as an AND operator. That is, only the articles containing ALL the words would show up in the Search Results window. Then, I installed Visual Studio 2005 with its MSDN Library side-by-side with my current VS .NET 2003 installation and I noticed that the spaces in the MSDN Library (October 2005) search window stop functioning as AND operators and began wor ...Show All

• Visual Basic msgbox not working after upgrading to XP - SP2

  I'm working on ASP pages with calls to COM+ DLL on XP platform. I wrote a method that simply call "msgbox" and display a value. I used this method to debug my ASP pages. It worked until I upgraded to XP-SP2. Now, it totally ignores msgbox call. Did Microsoft change the behavior of the msgbox or is there something else I need to do in SP2 to make this work I'd been searching the web for a couple of weeks and can't find any mentioned of this. Any help is appreciated. It's possible that SP2 adds some popup blocking to IE, I can't recall. I'd check the IE settings to see if there's a popup blocker run ...Show All

• Visual C# Application configuration error

  I have written a C++/CLI wrapper around some old C++ code so I can call it from C#, and a VERY simple demo app that calls the code. It works great. I've sent the release builds to the person I write this stuff for, and he gets an error when the code tries to call the C++ DLL : Could not load file or assembly 'HDRLib, version xxxx culture neutral publickeytoken=null. This application has failed to start because the application configuration is incorrect. The last bit is a verbatim quote of what HRESULT 0x800736B1 means, being the HRESULT it quotes. Again, this is managed C++ code being called from C#, works fine here. I have seen what ...Show All

• SQL Server Execute Mutiple Tasks In Debug Mode

  Maybe I'm missing something, but I can't find how to run multiple tasks in sequence while in Visual Studio debug mode. In DTS design mode I grew accustomed to right-clicking tasks one-at-a time, but in SSIS I find the additional step of having to exit Debugging mode after every task gets old after a while. There must be a way to start execution at a certain task and have the package continue all the way to some other specified task. It would also be nice to have every task in a Group execute in sequence and stop (even if connections continue beyond the group). I could even settle for repeatedly clicking the Continue button in Debug mo ...Show All

• .NET Development GPO for controlling Runtime Security Policy

  Hi all, changes made to settings in the ".NET Framework 2.0 Configuration" regarding the Runtime Security Policy end up in a file named C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\security.config. Right In our case we would like to add a trust to an URL in the LocalIntranet_Zone codegroup. Is there any way to controll these settings via a Group Policy or does the changes have to be applied with a .MSI/caspol.exe Kind regards, /RikardN There's no direct GPO method for distributing CAS policy modifications, but you can deploy a policy MSI or a caspol script* via GPO.

• Visual Studio Has anyone written a MSI bootstrapper for Guidance Automation Toolkit (GAT)?

  Has anyone written a MSI bootstrapper for Guidance Automation Toolkit (GAT) Basically I want to go to the Setup Package properties in Visual Studio and hit the Prerequisites button and have Guidance Automation Toolkit listed as a prerequisite that I can choose from. I don't mind writting one and posting it if no one has already written one, but I will probably need someone to post what the InstallChecks will be for GAT. Thanks! I have a bootstrapper that I have written now, but I am unsure as to what I can ship with it. The easiest thing to do is to embed the GAT/GAX msi inside the bootstrapper ...Show All
