Active X edit control

I am currently writing an app that needs text to be entered directly to the display. I have tried using an activex edit box to enter the text and it works just fine. However now I need to be able to select the control, move and resize the control during execution time. Any idea how I can go about doing this ? These controls are created and added during run time.

I am using VC++ 5.0 and the activex control used is Microsoft Forms 2.0 Textbox. Is there a better alternative control out there ?

When you create the control at runtime I assume you have a CWnd* to it. (CWnd::CreateControl(...))
Can't you use that ??

CWnd::SetFocus();
CWnd::SetWindowPos(...);

Why don't you just use a normal Windows Edit control ?
Use SetWindowPos or MoveWindow etc. to move it

The Microsoft Forms TextBox is actually the standard windows edit control.

Actually, I believe the CEdit control is the "standard" windows edit control.  Try using SetFocus and SetWindowPos as Bridge suggested.  By using the MFC CEdit control, you won't have to redistribute an ActiveX control.

Where are you using ActiveX Edit Control? in Dialog Application or App Wizard Generated project? In MFC Environment ideal solution is CEdit class. This class encapsolates the normal window's Edit control. Consult MoveWindows, SetWindowPos methods in VC++ help.

You use a CEdit control class. If you are placing the control using the VC++ resource editor, create a variable of type 'control' for this edit box in the 'Member Variables' tab of 'Class Wizard'. This will give you an object of class CEdit. Using this object you can call 'MoveWindow' to size the window or call 'SetWindowPos' to move the window.

Now your control can have two states: one when it is selected for resizing or moving and second when its working normally. You can provide an option like double clicking or clicking the mouse with some key like shift or ctrl down. When you get this message you can change the state of your control from normal to selected. Similarly for some other message like right mouse click or mouse click with some key, you change the state back to normal.

Now you have a bool variable that keeps the state of your control. When the state is "selected" you capture mouse events like WM_MOUSEMOVE with WM_LBUTTONDOWN. In this case you move the control using SetWindowPos. You can check the position of mouse cursor when it started moving and move the window relative to the mouse cursor movement. You will have to get the mouse position when in the selected state. When the mouse is over the border you change the cursor to 'sizing cursor' and when its a sizing cursor and you get mouse move with L button down message you resize the window using MoveWindow in the direction the mouse is being moved. Similarly when the mouse cursor is inside the control change it to 'move cursor' and move the control using SetWindowPos.

This will take some effort but it will definitly solve your problem.
