On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If
Next

I am trying to check two colors against each other with this Test but it does not appear to work. Can anyone suggest what I am doing wrong. :-
Do While (ptColor = Panel1.BackColor)
lft.X += 1
secPt = PointToScreen(lft)
ptColor = GetColor()
cnt += 1
Loop
When I look at the ARGB values at a breakpoint ,then numerical values of the three component colors are the same but the loop does not get executed. ?

I'm creating a little program to help my students to understand colour-mixing in Hex for their Web Design course. What I've got so far, is as follows: The user is presented with 3 sliders (one each for R, G and B) and a button. The 3 sliders each go from 0 to 15 - and when the user hits the "Show me!" button, Select Case jobbies translate the 0 to 15 values as seen here:

Inverting red (255,0,0) gives cyan (0,255,255). visual basic express 2008 this is what i have, what do i need to make changes to in order to accomplish this?

I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click
Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)
[Code]......
This works to do what I need to get done, I just need each circle to have a random color as it is drawn.

Essentially I am searching an array for colors. If there is no input, on button click you get an error. If the color does not exist you get an error. If it exists then it tells you. The latter two events are not happening.
Public Class Form1
Dim count As Integer
Dim Crayola() As String
Private Sub Form1_Load(ByVal sender As System.Object, ByValue As System.EventArgs)

I am trying to create an array of colors. approach 2 doesn't work and I do not know why
Code:
'approach 1: works
Dim list As Color() = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
Code:
'approach 2: fails.. why?
Dim list() As Color = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
If instead I wish to create an array of strings, both approach works, that's weird.

I know how to have alternate row colors with ListView. But how about with ListBox? I've run a search. I read in some web sites where they say you can't. Is that true? Meanwhile, I've done something like:
For i As Integer = 0 To ListBox1.Items.Count - 1 Step 1
If i Mod 2 = 0 Then
ListBox1. BackColor = Color.FromArgb(150, 250, 255)
Else
ListBox1. BackColor = Color.White
End If
Next i
with ListBox's DrawItem event. And it doesn't work.
