When you minimize the second form it shows up as a box in the corner of the screen. It does not minimize all the way down to the taskbar. Is there any way I can get this form to minimize to the taskbar?

If you want to use a VCL form, then ignore JD's suggestion about using CreatWindowEx() directly. Override the form's inherited CreateParams() method and assign your dwStyle and hWndParent values there instead, ie: void __fastcall TMyForm::CreateParams(TCreateParams &Params) { TForm::CreateParams(Params); Params.ExStyle |= WS_EX_APPWINDOW; Params.WndParent = GetDesktopWindow(); } Gambit --- Outgoing mail is certified Virus Free.

Although, now there is a minimized version of the MainForm in the taskbar when the program starts. It doesn't allow you to show it either because of the Visible=false property. How do you suggest I hide this second minimized window?

Making a secondary form minimizable to the TaskBar should not have effected any other forms, as they are all independant of each other. If your MainForm is not remaining invisible then you must have introduced something else into your code that you haven't shown yet. Please show your actual code.

When certain options are configured, the secondary form is hidden and the MainForm is shown. I've added your CreateParams function to this secondary form, but there seems to be two entries on the taskbar. I just set Application->ShowMainForm = false; before the Application->Run(); Then when the secondary is hidden, I just use FormName->Hide(); and FormName->Show(); to bring up the MainForm.

This is the Windows entry point: snip I do not see you calling ShowWindow() at all. Otherwise the rest is just using Show() and Hide(). What portions of the code would you like to see? The code where you are actually showing and hiding your forms. Gambit --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system ([url]http://www.grisoft.com)[/url].

You're supposed to be using ShowWindow() to show/hide the main taskbar button when appropriate. For example: WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) { //... ShowWindow(Application->Handle, SW_HIDE); Application->ShowMainForm = false; //... return 0; } // when showing the main form ShowWindow(Application->Handle, SW_SHOW); MainForm->Show(); // when hiding the main form again ShowWindow(Application->Handle, SW_HIDE); MainForm->Hide(); Gambit --- Outgoing mail is certified Virus Free.
