This question is more academic than practical and doesn't involve any one specific language. For the sake of discussion, we'll use Win32 API. What is the most appropriate way to create a window with the following behavior goals: Z-Order is lower than every other window except the desktop surface. Cannot be made to appear on a higher ...

I use system(), which on the mac makes the stdout of the invoked program, be written in the stdout of the Perl program, which is what i want.

I've been encountering a problem when trying to query all available resolutions on some nvidia cards under Win7. for(int i = 0; EnumDisplaySettings( deviceName.c_str(), i, &dm) != 0; ++i) reports resolution which aren't available like 866 x 650. Most supported resolutions on the other hand are missing. Changing driver/monitor setup di...
In C# I can do the following: DirectoryInfo di = new DirectoryInfo(System.Environment.GetEnvironmentVariable("ALLUSERSPROFILE")); Which will get me the path to the all users profile. In C++ I can use the SHGetFolderPath, but it does not seem to have a CSLID for all users. Is there an equlivant function that I can blow the %ALLUSERSPR...
I'm writing a DLL that needs to call a separated DLL dynamically multiple times. I would like to keep the callee loaded and then just unload it when my DLL is unloaded. But according to Microsoft, that's a bad idea. The entry point function should only perform simple initialization tasks and should not call any other DLL loadin...
I'm writing an (unmanaged) C++ class to wrap the Windows PropertySheet. Essentially, something like this: class PropSheet { PROPSHEETHEADER d_header; public: PropSheet(/* parameters */); INT_PTR show(); private: static int CALLBACK *propSheetProc(HWND hwnd, UINT msg, LPARAM lParam); }; The constructor just i...
In many of my Access (2002) programs I use the GetOpenFileNameA and GetSaveFileNameA functions from comdlg32.dll. I often set the initial directory to the user's My Documents folder (using calls to SHGetSpecialFolderLocation and SHGetPathFromIDListA from shell32). This all works fine under Windows XP. However, I recently switched to W...
Hello, I've been successfully creating a .net mutex like this: SingleIns = new Mutex(true, AppName); for a while. It works in XP, Vista, but apparently not in Windows7. So I need to make an interop call to a Win32 library so other Com components can identify the mutex. I found the following code, but the Win32Calls. is not found... is...
I have another question open regarding an error I'm experiencing with the horizontal scrollbar of a RichTextBox not functioning properly and am not getting much response. It came to me that I might be asking the wrong question. My new question is how do the scrollbar properties get set/controlled. I know I can SendMessage to change the...

How can I find the address of a WndProc (of a window of another process). Even if I inject a DLL and try to find it with either GetClassInfoEx() or GetWindowLong() or GetWindowLongPtr() I always get values like 0xffff08ed, which is definitely not an executable address. It is according to MSDN: "... the address of the window procedure, or...
I've got a Win32 process that is compiled and packaged in both 32-bit (x86) and 64-bit (x64) variants. I'd like the x86 variant to refuse to run on a 64-bit version of Windows (i.e. WOW64). Is there any way to do this by setting linker flags? If not, what do I need to do? ...
How do you call IFileOpenDialog and IFileSaveDialog from VBA? According to Microsoft, applications written for Windows 7 and later should use IFileOpenDialog/IFileSaveDialog API calls instead of GetOpenFileName/GetSaveFileName (see Using the Common File Dialog). This is especially important for full Library support. ...
Hi, I want to wait for and close a modal form (a popup) from another application, as soon as it appears. I want to do this from VB.NET, but suggestions in C# should be easily translateable. I can hard-code the modal popup's caption in my app, since it's long and unique. What I want to do is simulate either the user clicking on the close...
Long story short: I'm trying to write an app that'll dump IE's history to a text file.

I finally got the program to dump the history, but it ONLY WORKS if I pu...

Several have pointed out that there exists an undocumented message that retrieves the IShellBrowser interface pointer from the common dialog HWND for the file open & save dialogs. But there is conflicting information (or no information) on whether that pointer is AddRef'd, or if it is just the raw address returned, and no Release() shou...
