Hi, BCB5 I have an app that loads a dll form and in this form I call a colordialog. After clicking the OK or Cancel in the colordialog, the form appears to go behind the app. I tried using a variety of ShowWindow's, but don't seem to have any way of control the MainForm from within the dll. Any ideas on how to keep my dll form on top? Regards, TT

Is it a VCL form? Is the form in a DLL or a package (BPL)? If you are using a VCL form in a DLL, are you setting the DLL's Application->Handle property before trying to create any forms in the DLL? If you are not doing this, you should. The DLL's Application->Handle property must be set to the handle of the EXE's main window otherwise you will get odd behavior like that which you are describing. - Dennis

OK, thanks Dennis. Yes, VCL. I'll take this approach.
