You'll have to invoke the API I guess

You mean .NET does not have something for that I have to use win32? Dead | X|

I don't like it if I have to do it that way. Roll eyes | :rolleyes:

I might be wrong Mazy! I guess we both can wait for James Johnson to come back from his weekend trips to answer this question!

If you are talking about just getting the currently active WinForm in a non-mdi application it would be

System.Windows.Forms.Form.ActiveForm

If you wish to know which control it would be

AciveForm.ActiveControl

For a MDI it would be

System.Windows.Forms.ActiveMDIChild

If you are referring to any windows external to your application, I believe you will need to use the Win API.

As Nish said, and you feared; you have to resort to the Win32 API. This is because you can't create a Control object (the base class for Form) from an arbitrary HWND, only for one which a Control object already exists.

Perhaps in V.NEXT we'll have such support for a limited window class Smile | :)

Multiple forms

I know this is a very basic question but could someone please tell me how to create for example a dialog box for getting user settings ect for my application, or even an about dialog box. Is it as simple as right clicking in the explorer and adding another windows form? If so how do I get my program to display it?
Thanks in advance,
Paddy.

You pretty much have it. It only requires adding another WinForm to your project. In the code you (assuming the name of the new WinForm class is 'Form2') simply something like:

Form2 dlg = new Form2();
dlg.ShowDialog();

when you want to display the form. If can also use "dlg.Show()" if you wish a modeless window.

An inherited Winform is a cool little beast that allows you to inherit the WinForm from a WinForm that you create in another library (DLL) or you own project (if you compiler before you inherit). You can define one form as your base form with controls, then you inherit that form. It will build a form that looks just like the base form. You can add items to the form, you just cannot modify any of the items on the base form. But you can, at any time, modify the base form and those modifications will bubble up to all inherited forms.. Cool!

This is good for a Wizard type window where you have a certian layout. Another use is to simulate a skinning window by creating the base winform with different graphics or colors then dropping in the any of the modified base class DLLs thus changing the appearance of all inherited WinForms that inherit from that base WinForm.

There are many uses Inherited Forms!

MICROSOFT WORD

Is it possible to open/create a Microsoft Word document in a C# application and to display the document INSIDE the C# application window?

In other words, I want to attach the MS Word window to my WinForm object. Is there a way to treat a Word document like a .NET control?

Thanks!
Johannes

Hi
Does anyone know how to set margins on edit controls (textbox, combobox, etc) in C# by using managed code?

I used to do it by sending EM_SETMARGINS message in VB6, but I was wondering if there was a way natively supported by .NET.

Thanks,

TreeView firing MouseUp when mouse is still pressed

This is a ***BUG***, create a simple C# Windows based form. Drop a treeview on the form, add a MouseUp event handler for the TreeView. Add Console.WriteLine("MouseUp Fired");

Start the application, press and hold Left mouse button inside of the treeview, note the MouseUp event is fired even though the mouse button hasn't been released?

Work arounds anybody? Confused | :confused:
