Why do you say that it behaves like a modeless dialog?
Are you able to switch back to the parent dialog when the modal dialog is shown?

//Ilantus
fetchPortalURL((WCHAR)"");

return S_FALSE;
}

void fetchPortalURL(WCHAR username) {

DialogBox((HINSTANCE)g_hinst, MAKEINTRESOURCE(IDD_DIALOG1),NULL, InputBox_WndProc);

}

The third parameter which is the parent is given as NULL.
Set the parent to the desired window to make it modal.

Can i get text color of title bar?

12-Feb-13 0:02

The third parameter to DialogBox is still NULL - DialogBox((HINSTANCE)g_hinst, MAKEINTRESOURCE(IDD_DIALOG1),NULL, InputBox_WndProc);
You need to specify the handle to the parent window here.

Hi,

Using the GetProcAdress I wanted to get the exported address of a function

When it returned zero I double checked with depends.exe to ensure the function was exported

I then went to assembly mode to see what happens and noticed that after the call statement a value was returned in the RAX register but there wasn't any code to move the RAX register value to my FARPROC data member

I then turned optimization off #pragma optimize("",off) and the same code generated "mov FARPROC,rax" am I missing some compiler to flag to make this happen without turning optimization off

Thanks

Thanks
