changing Control colours

Hi,

This question has 2 parts :-

(1)I'm writing a GUI where I set the BackColor property of a text-box to yellow when it gets focus & back to white again when it loses it. This works fine except for when you start typing text in the box which comes out black with a grey back-ground around the text - it's the grey background I'm trying to get rid of; any ideas please?

(2)Similarly, when a check-box or radio-button gets focus, I would like to set only the little square box where the tick goes to be yellow when it gains focus, but setting the BackColor property in this case colours every part of the control EXCEPT the little square box. Any ideas for this too?

Many thanks.

I do not see the same effect of the gray background surrounding the text:

Private Sub Text1_GotFocus()
    Text1.BackColor = vbInfoBackground
End Sub

Private Sub Text1_LostFocus()
    Text1.BackColor = vbWhite
End Sub

What color mode is your system set to?
8 bit, 16 bit, 24 bit, etc.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Unfortunately, the checkbox uses bitmaps to display the little checks, so it is not possible to change the color.  You would have to either make your own control or find a third party control which supports this.

Sorry, I don't know how to check my color mode & second when I used vbInfoBackground this gives an annoying white background effect around the text. But really I need to use true yellow as vbInfoBackground does not stand out enough. By the way I increased the points to 200. Thanks.

Thanks Eric37 for info about check-boxes. As for monitor color mode, I'm still not sure about this - I'm using 256 colors, small fonts, 1024/768 pixels, 75 hertz refresh frequency - hope that helps. Cheers.

256 colors

Ok... is your yellow background colour a dithered colour?

OK....

What happens if you set your text box bacground colour to &H0000FFFF&

Text1.BackColor = &HFFFF&

I tried 256 colours and I get the same effect for dithered colours. Solid colours, like the one above work fine.

So - use solid colours if you must have 256 colours.

have you tried using a boolean variable to set the background and maintain it with the key down event??

Dim color As Boolean


Private Sub Text1_GotFocus()
    color = True
    Text1.BackColor = vbYellow
End Sub

Private Sub Text1_KeyDown(KeyCode As Integer, Shift As Integer)
    If color = True Then
        Text1.BackColor = vbYellow
    Else
        Text1.BackColor = vbWhite
    End If
End Sub

Private Sub Text1_LostFocus()
    color = False
    Text1.BackColor = vbWhite
End Sub

Change from 256 colors, to HiColor (16 bit) and see if the problem goes away.

Also confirm you are using the standard TextBox, not the windowless Textbox.
