I want to add buttons etc.... to a form but it tells me that the resource ID has already been used. Although this is true that it has been used, it was used on a different form, so why the problem? I have a IDC_ADD button one one form and IDC_ADD on a different form with no complaints, so why with certain ID's?
Any ideas?

Resource Id's are defined only once. Give a look at you resource.h file.
However two resource ID's can have the same value.
For example:
#define IDC_ADD 135
#define IDC_ADD2 136
...
...
#define IDC_QUIT 135.
This case you can not mix IDC_ADD and IDC_QUIT in the same form because they have the same value. (135)
The duplicates are normaly caused when copying resources.
Perhaps you want to set IDC_ADD to a button int your form but you already have a control with the same value (but other Id).
Other option is you can even open the script1.rc file in text mode(notepad) and edit the resources there itself.
