The problem is likely that you’re starting your counter variables at 1, then using that as an index into the array, but array’s are zero-based in c# so you’re essentially skipping the first item at 0 and then trying to access an item that’s out of the bounds of the array. It’s also not accurate … Read more

You could use GDI+ (and more specifically the Graphics class): // Load an existing image into a Graphics object using (var image = Image.FromFile(@”c:\work\input.png”)) using (var gfx = Graphics.FromImage(image)) { // Draw a line on this image from (0x0) to (50×50) gfx.DrawLine(new Pen(Color.Red), 0, 0, 50, 50); // save the resulting Graphics object to a … Read more

This doesn’t really make a lot of sense. Short of disabling the mouse cursor entirely, I don’t know how you would possibly achieve this. Even if there were a way of “ignoring” mouse clicks on the tab control tabs, that would be incredibly bad UI. As far as the user would be concerned, your application … Read more
If you’re using an error provider and handling onvalidating, it should look like this: private void textBox1_Validating(object sender, CancelEventArgs e) { TextBox tb = sender as TextBox; if (tb.Text.Length > 0) { e.Cancel = true; errorProvider1.SetError(tb, “Please leave this textbox blank!”); } else { errorProvider1.SetError(tb, “”); } } This will prevent you clicking off the … Read more

Which method you use will depend on what type of data you are using. To save the file in your application directory, you can get the path using AppDomain.BaseDirectory So for example if you’re … Read more
