[c/c++][winapi] MessageBoxIndirect question

[code_ninja]

Here's the code:

HINSTANCE hDllModule = LoadLibrary("shell32.dll");
MSGBOXPARAMS mbp;
mbp.hwndOwner = hwnd;
mbp.hInstance = hDllModule;
mbp.lpszText = " ";
mbp.lpszCaption=" ";
mbp.dwStyle = MB_OK|MB_USERICON;
mbp.lpszIcon = MAKEINTRESOURCE(6);
MessageBoxIndirect(&mbp);

I get no icon. (Yes, the icon id is valid.)

Is it possible to pass a non-resource to lpszIcon? Such as a path to an ico file, an icon from a dll, or an icon handle?

If so, how?

MSGBOXPARAMS

lpszIcon: This parameter can be either a null-terminated string or an integer resource identifier passed to the MAKEINTRESOURCE macro.

Are you trying to retrieve the 6th icon resource from shell32.dll? You should be checking to make sure hDllModule is not null. Also, I think you should be using LoadLibraryEx("shell32.dll", 0, LOAD_LIBRARY_AS_DATAFILE).

[code_ninja]

Yeah, I know about that. Just wondering if it is possible.

EDIT:

All the values are valid.

[boogerjones]

Then try using GetModuleHandle instead of LoadLibraryEx

I got it to work. Thanks boogerjones.

I got it to work. Thanks boogerjones.

What's the final solution?

What's the final solution?

Well, it turns out the Dll was invalid. Yeah, my bad. But, there's another problem.

I used the PickIconDlg function that returns the icon index number.

Is there a way to get the resource id from the index?
