I'm leaning some win32 programming, and the WinMain prototype looks like: int WINAPI WinMain ( HINSTANCE instance, HINSTANCE prev_instance, PSTR cmd_line, int cmd_show ) I was confused as to what this WINAPI identifier was for and found: #define WINAPI __stdcall What does this do? I'm confused by this having something at all ...
On input validation, I'm using balloon tips instead of message boxes. My problem is that on Vista, they have the old XP style with the rounded corners, not the newer more rectangle like appearance. I've tried creating them using CreateWindowEx and tooltips_class32 or showing the Edit's associated balloontip using SendMessageW and EM_SHO...
[This code is called from within the Inspector.Activate event handler (first call), i.e. right before the inspector window is actually shown.] For "native" mail inspectors I can simply QI the Inspector interface to IOleWindow and call its GetWindow method. However, this will not work for Word inspectors which are in fact instances of Wo...
I'm trying to use SetWindowsHookEx to set up a WH_SHELL hook to get notified of system-wide HSHELL_WINDOWCREATED and HSHELL_WINDOWDESTROYED events. I pass 0 for the final dwThreadId argument which, according to the docs, should "associate the hook procedure with all existing threads running in the same desktop as the calling thread". I a...
I'm writing a function for an installer DLL to verify the Authenticode signature of EXE files already installed on the system. The function needs to: A) verify that the signature is valid. B) verify that the signer is our organization. Because this is in an installer, and because this needs to run on older Win2k installations, I...
How can I determine if a Win32 thread has terminated? The documentation for GetExitCodeThread warns to not to use it for this reason since the error code STILL_ACTIVE can be returned for other reasons. Thanks for the help! :) ...
The 'attach to process' dialogue box on VC6 running on win 2003 (I believe vista as well) has no processes to attach to in it... I've tried logging on as an administrator and running as an administrator but no luck. Any other ideas? ...
Hello everybody, I am thinking hard about how to play with access rights on several platforms. Now I am reaching Microsoft Windows and permissions on NTFS files/directories. I must say that I am working in C language. My question is pretty general. I have a username and a file path. Do I need more information to check if the user has ...
Hi there, I'm using ActiveState Perl on Windows Server 2003. I want to create a directory on a Windows NTFS partition and then grant a Windows NT security group read access to the folder. Is this possible in Perl? Would I have to use Windows NT commands or is there a Perl module to do it? A small example would be much appreciated! ...
Having the window handle for an open application, I'm able to use the GetWindowText function to retrieve the text from the title bar of the app. I would like to take this a step farther and retrieve the icon associated with the same app. How might I go about doing this? I looked through what I thought would be the relevant Win32 API...
I can use CreateProcess to launch an EXE. I want to have the contents of an EXE in a memory buffer and do CreateProcess (or an equivalent) on it without having to write it to a file. Is there any way to do that? The backstory : we make games. We send a plain EXE to our distributors, which then wrap it using their favorite DRM and sell i...
When measuring network latency (time ack received - time msg sent) in any protocol over TCP, what timer would you recommend to use and why? What resolution does it have? What are other advantages/disadvantages? Optional: how does it work? Optional: what timer would you NOT use and why? I'm looking mostly for Windows / C++ solutions, b...
The function CreateFileMapping can be used to allocate space in the pagefile (if the first argument is INVALID_HANDLE_VALUE). The allocated space can later be memory mapped into the process virtual address space. Why would I want to do this instead of using just VirtualAlloc? It seems that both functions do almost the same thing. Mem...
Ok, one for the SO hive mind... I have code which has - until today - run just fine on many systems and is deployed at many sites. It involves threads reading and writing data from a serial port. Trying to check out a new device, my code was swamped with 995 ERROR_OPERATION_ABORTED errors calling GetOverlappedResult after the ReadFil...
I have an application that can list the opened windows of the current session. It uses the EnumWindows method from the user32.dll. I would like to run this code from a windows service, but as the service is not attached to a user session, it returns nothing obviously. So the question is, how can I enumerate the open windows of another ...
What win32 calls can be used to detect key press events globally (not just for 1 window, I'd like to get a message EVERY time a key is pressed), from a windows service? ...
Does anyone know where I can find an example of how to determine if the Maximize and/or Minimize buttons on a window are available and/or disabled? The window will not be in the same process as my application. I have the hWnd and I have tried using GetMenuItemInfo, but I can't find any good samples for how to do this. Thanks! ...
I have an application which is a relatively old. Through some minor changes, it builds nearly perfectly with Visual C++ 2008. One thing that I've noticed is that my "debug console" isn't quite working right. Basically in the past, I've use AllocConsole() to create a console for my debug output to go to. Then I would use freopen to redire...
I have a Windows GUI application that's using the QT framework (currently version 3.3.5, might change to QT4). I want to combine other Windows GUI applications in the main application. I can't use the widgets directly in the main application due to several constrains which I can't control. The final layout should look like this: Curr...
I'm attempting to learn basic Win32 programming and running into a frustrating problem. I wish to convert a variable (Call it NumClicks) and display it as the application name (as part of a string). From what I've seen, going from int + some block of text to a char* is problematic, because converting it to the requisite end data type(LPC...
