Invert Scroll Bar Value?

Sep 5, 2011

I am trying to have a vertical scroll bar on a form.I would like the value of the scroll bar to be, from top to bottom, 35 to -35.

I tried to set the minimum value to 35 and max to -35, but vb wont allow it.

Is there a way to do this without catching the value when it's changed and storing the inverted value in a variable?

VS 2010 Can't Invert Checkbox Selection

Nov 17, 2009

I'm trying to set my software up so that you could invert the selection if needed.

This is the code I have so far:

Private Sub InvertSelectionToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles InvertSelectionToolStripMenuItem.Click
If Me.chk_7zip.Checked = True Then

[Code]....

I already figured out how to Select all and Select none and it seems to know that when I want to invert the selection if there is no checkmark in the checkbox that it should check it but if I hit it again or if was selected previously it won't uncheck it..

As the image can vary from dark to light no one text colour can assure that the text will be readable.

Mar 5, 2012

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

I'm creating a little program to help my students to understand colour-mixing in Hex for their Web Design course.

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:

50 Random Circles With Different Colors?

Feb 9, 2011

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.

How To Create Array Of Colors

Oct 25, 2009

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.
