Hi! im trying to create modal dialogbox on run-time , and this is the code im using: DLGTEMPLATE dTemplate; dTemplate.style = WS_POPUP | WS_SYSMENU | WS_CAPTION | WS_VISIBLE; dTemplate.cdit = 0; dTemplate.cx = 450; dTemplate.cy =100; dTemplate.x =0; dTemplate.y =0; DialogBoxIndirect(CApp.GetHInst(),&dTemplate,CApp.GetHWnd(),(DLGPROC)DlgProc8); while CApp.GetHWnd() is the parent hwnd and CApp.GetHInst is the parent instance when im trying to create the dialog in that way i get this error: ERROR_RESOURCE_NAME_NOT_FOUND somebody knows why? thanks . roy.

According to my copy of the MSDN Library "DLGTEMPLATE structure is always immediately followed by three variable-length arrays that specify the menu, class, and title for the dialog box." In your code you seem to be forgetting to take care of these "variable-length arrays".

Here is how the MSDN Library handles them:


lpw = (LPWORD) (lpdt + 1);
*lpw++ = 0; // no menu
*lpw++ = 0; // predefined dialog box class (by default)

lpwsz = (LPWSTR) lpw;
nchar = 1+ MultiByteToWideChar (CP_ACP, 0, "My Dialog",
-1, lpwsz, 50);
lpw += nchar;


lpw is a LPWORD, lpwsz is a LPWSTR, and lpdt is a LPDLGTEMPLATE. Obviosly they dynamically allocate the DLGTEMPLATE structure and you would need to alter the code to adjust for the fact that you do not.
