it is possible, although it takes alot of programming. You have to create the DLGTEMPLATE and DLGITEMTEMPLATE structures in memory. That means you must fill in a structure for each control on the dialog. Then pass the entire unified structure to CreateDialogIndirectParamA(...) and then call ShowWindowA(...) I'm sorry i don't have a 'C' code sample of how to do this, all i have is a BASIC version written in my own language, not much good if you aren't familiar with it.
