You cant do what youre asking for for two reasons:

1) There is no "include" capability in VB. you would have to cut and paste the text into the VB form.

2) The syntax of C header files is totally different to the syntax of VB, so even if you cut and paste the whole header file, it will cause compilation errors in VB. You need to edit the header file to turn it into VB syntax.

If you want to include common declarations in your VB program (API functions & constants) then I reccomend you get yourself a copy of the VB Type Library. To use this you include it as a Reference in the project, then all the declarations are available to you in your program.

you can get the VB Type Library from :

unfortunately you will still find there are some declarations not in this (though not that many). You will have to do these "by hand" still. But at least the majority are done for you.

Hope this helps.

You can write this statement:
#Const include = "vbconst.h"
but it won't include a file. :-)
To include a file, press Ctrl+D, or use menu Project, Add Module, or drag file from Windows Explorer to VB Project Explorer.

If it is a c header, it will be meaningless in VB unless you rewrite it in VB syntax.
