View 3 RepliesGet Pixel Color Of Label?
Oct 8, 2009I am creating a custom tooltip label. My problem is auto resizing it (particularly height).The thing to note here is that the label i am using is an infragistics label, and i can have different fonts and formatting inside the label which means i cant just measure the text height based on the font because the label will contain multiple fonts.The only thing i can come up with is to make the label the height of the screen, and then perform a loop which scans the colour of each row of pixels starting from the bottom, decreasing the label height each time until it finds some pixels which <> the backcolor of the label (which would indicate that there is some text there).This is the only reliable way i can think of to make this happen, but im having trouble finding out just how exactly to get the color of the pixel at the given point.I did find one method of getting the pixel color, but the problem was that it when i requested it in the form_load it didnt return the right color because the screen wasn't painted (i guess).

Jun 25, 2010I've recently been working on some VB.NET programs, grab the value of the color of a pixel on my screen(Out of my WIN32 Application).
I need this so I can make a little bot that automatically pushes buttons for a online game called "JamLegends"(http:jamlegends.com). Its kind of like Rock Band, and if I can grab the color, then I can simply used 'sendkeys' to press buttons to make the bot work.
Edit: This is for a project in school. We need to make something that will make a program that will make something easier to work with or use(In my case, JamLegends). I have nothing to work with, I've researched a bit but I found nothing that can grab pixel color values.
