Hey, guys. I'm VERY new to programming windows manually and I'm stuck on this problem. I'm trying to follow this tutorial:
http://www.winprog.org/tutorial/dialogs.html[
^]
The program window came up fine until I tried to add the dialog box. The dialog box uses "menures.rc and menures.h". I included the menures header in the main file, and that stopped the "undeclared" errors. I guess now I need to declare the "IDD_ABOUT" and "ID_HELP_ABOUT" in my main function, or something. But, I have no idea how. Thanks in advance for the help.
The error is: expected primary-expression before '[symbol here]'
I put notes next to where the error occurs.
