Win32 toolbar Programming

I tried to program a windows toolbar and I thought that the code was right but for some reason it does not display the custom bitmap that I am trying to use. It displays the button but no bitmap on it. This is the code:

 INITCOMMONCONTROLSEX initctrs;

 initctrs.dwSize = sizeof(INITCOMMONCONTROLSEX);

 initctrs.dwICC = ICC_BAR_CLASSES;



 InitCommonControlsEx(&initctrs);



 TBBUTTON button[1];



 button[0].iBitmap = 0;

 button[0].idCommand = IDM_NEW;\\<-From resource file

 button[0].fsState = TBSTATE_ENABLED;

 button[0].fsStyle = TBSTYLE_BUTTON;

 button[0].dwData = 0L;

 button[0].iString = 0;



 HWND tool;

 

 tool = CreateToolbarEx(hwnd,

                                      WS_CHILD | WS_VISIBLE | WS_BORDER,

                                      IDB_BIT,\\ <- IDB_BIT is the Bitmap resource.

                      1,

                      hInst_menu,

                      IDB_BIT,\\ <- IDB_BIT is the Bitmap resource.

                      button,

                      1,

                      16,16,16,16,

                      sizeof(TBBUTTON));

I do not know if I am missing something obvious or if I need to Load the bitmap before I use it in this context. Any help will be great.

Re: Win32 toolbar Programming

You can load the bitmap first, using LoadImage. Then you would want to change hInst_menu in your CreateToolbarEx call to NULL, and put the HBITMAP handle where IDB_BIT is.

You might want to try something else, first though. I'm not 100% sure this will work, but it's worth a shot. It looks like IDB_BIT is the numeric ID of the bitmap. Correct? You may want to try MAKEINTRESOURCE(IDB_BIT), instead of just IDB_BIT.

Re: Win32 toolbar Programming

Loading the image first worked perfectly but I also tried MAKEINTRESOURCE and it did not work because it was telling me that I could not convert the UINT from the MAKEINTRESOURCE into LPWSTR. I tried typcasting but that still did not work. I do think that there is a way to do it without manually loading the bitmap because I saw it in a tutorial that I found but I did not go totally in depth.

Fixed the LPWSTR issue but still does not work.
