Using 'SendMessage' to manually drag a form

[sphynx]

Hi,
I have managed to allow a form to be dragged by using the _MouseDown Sub that is triggered with a picturebox upon mouse down...

It works quite well, however 'ReleaseCapture' is also used, and this prevents _MouseUp from being triggered.

Why is this important you may ask?
Becuase on _MouseDown, 'pic_Caption.BackColor = 255' is used (pic_Caption is the picturebox name) changing the color of the picturebox to red, which signified that the user is dragging the window.

So I need something to be triggered when the user has stopped dragging the form to return pic_Caption.BackColor to it's original color, which is black.

'pic_Caption.BackColor = 0'

Please take a look at the source included and share your idea's/solutions.

Thanks,

I use the following code to simulate a mouseover/mouseleave event. When the mouse is over my command button, I change the backcolor to cyan, and when the mouse has left my button I change it back to the standard gray

If (X < 0) Or (Y < 0) Or (X > cmdAbout.Width) Or (Y > cmdAbout.Height) Then ' the MOUSELEAVE pseudo-event
               ReleaseCapture ' the mouse is no longer over the button, change backcolor to gray
               cmdAbout.BackColor = &HC0C0C0
        ElseIf GetCapture() <> cmdAbout.hWnd Then ' the MOUSEENTER pseudo-event
               SetCapture cmdAbout.hWnd ' the mouse is over the button, change backcolor to cyan
               cmdAbout.BackColor = vbCyan
        End If

Problem: When a user clicks the button it remained cyan even after the mouse had left. Solution: I put

ReleaseCapture
cmdAbout.BackColor = &HC0C0C0

in the buttons click event. So, my suggestion would be to change your mouseevent to the following

Private Sub pic_Caption_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
pic_Caption.BackColor = 255
If Button = 1 Then On Error Resume Next: FormDrag Me
ReleaseCapture
pic_Caption.BackColor = 0
End Sub

PS: I did this on your form and it worked like a champ.

Hey, thanks for the help Hack.
I've added some more code and come across a new problem, I wanted to allow the window to be resized manually.

See if you can help me out and check out the code attached.
