I have a simple win32 application that i wrote that loads a .bmp(hard coded filename) and displays it. Right now it has a menu at the top that only has File -> Exit command.

I would like to add a menu item that opens a dialog to browse and open any .bmp that i want.

thanks

You will have to use the win-api-function GetOpenFileName and pass it an OPENFILENAME-structure. You can find further information on all those parameters and combinations possible here:
http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/userinput/commondialogboxlibrary/commondialogboxreference/commondialogboxfunctions/getopenfilename.asp
and here:
http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/userinput/commondialogboxlibrary/commondialogboxreference/commondialogboxstructures/openfilename.asp

For the menu question: Add an 'Open'-option to your File-menu and give a unique ID, let's call it ID_FILE_OPEN. Add a WM_COMMAND-message handler and check whether LOWORD( wParam ) == ID_FILE_OPEN.
