[2005] testing colors in VB

Hi - newbie to VB - am using Textboxes to dispolay text and have the textboxes colored yellow, white and red depending upon their designation. I want to use the double-click event processing of the textboxes (using event handler) and take different actions depending upon the color of the textbox. I set the color as shown (this works OK):

TextBox1.BackColor = Color.Yellow

I attemp to test the color with the following (this does not work)

if TextBox1.BackColor = Color.Yellow then
' do something'
end if
if TextBox1.BackColor = Color.Red then
' do something else'
end if


This creates an error and does not work and I have not been able to find the way to test this and take appropriate action. Help would be appreciated in the way to test the BackColor existing and take action depending on what this color is.

Thanks and cheers

use the .Equals method like this ...

VB Code:

[COLOR=Blue]Private Sub[/COLOR] Form1_Load([COLOR=Blue]ByVal[/COLOR] sender [COLOR=Blue]As[/COLOR] System.Object, [COLOR=Blue]ByVal[/COLOR] e [COLOR=Blue]As[/COLOR] System.EventArgs) [COLOR=Blue]Handles[/COLOR] MyBase.Load
        TextBox1.BackColor = Color.Yellow
    [COLOR=Blue]End Sub[/COLOR]
 
    [COLOR=Blue]Private Sub[/COLOR] TextBox1_DoubleClick([COLOR=Blue]ByVal[/COLOR] sender [COLOR=Blue]As[/COLOR] [COLOR=Blue]Object[/COLOR], [COLOR=Blue]ByVal[/COLOR] e [COLOR=Blue]As[/COLOR] System.EventArgs) [COLOR=Blue]Handles[/COLOR] TextBox1.DoubleClick
        [COLOR=Blue]If[/COLOR] TextBox1.BackColor.[B]Equals[/B](Color.Yellow) [COLOR=Blue]Then[/COLOR]
            MessageBox.Show([COLOR=Purple]"yellow!"[/COLOR])
        [COLOR=Blue]ElseIf[/COLOR] TextBox1.BackColor.[B]Equals[/B](Color.Red) [COLOR=Blue]Then[/COLOR]
            MessageBox.Show([COLOR=Purple]"red!"[/COLOR])
        [COLOR=Blue]End If[/COLOR]
    End Sub

Hi,

You could do something like this also;

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If TextBox1.BackColor = Color.Yellow Then
            ' do something'
            MsgBox("Yellow")
        End If
        If TextBox1.BackColor = Color.Red Then
            ' do something else'
            MsgBox("Red")
        End If
 
    End Sub

Change the color of yout textbox with another button and see the result.

Wkr,

thanks man

Thanks man - cheers

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.BackColor = Color.Yellow Then
' do something'
MsgBox("Yellow")
End If
If TextBox1.BackColor = Color.Red Then
' do something else'
MsgBox("Red")
End If

End Sub

could be:

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  Select Case TextBox1.BackColor
    Case Colors.Yellow
      'Yellow color code
    Case Colors.Red
      'Red Color code
  End Select
End Sub
