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'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:
this is what i need to do: In the right-hand label, invert the colors of the image. Hint: the inverting white should give black and inverting black should give white. 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.

A while ago I wrote something that was incredibly simple, however it was 3 years ago and I can't for the life of me find where I saved it(upgraded computers twice since then and a few things managed to disapear in the process) I tried for the last few days trying to figure out how I did it and realized that someone may be able to see what I cannot.

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.
