Hello guys,I'm new in BP forums as well as in programming.I just wanna ask a little easy question.Which visual studio edition you prefer would be better to use,VS2008 or VS2010?
And I don't speak English really well,so just underestimate it.
Thanks in advance...

Am I the only person on this forums who waits for this HL2 episode since 2008? Do you think they will release this episode?

So, I recently received a professional e-mail from someone who works above me. This e-mail was written in Comic Sans. Because of this, I couldn't take any part of the e-mail seriously.

Are there any fonts that you guys just can't stand?

Hey guys,

I'm using the following code to pull data from two tables in my MySQL database. Currently, the data is being loaded directly to the TextBox controls on my form.

What I want to do is this, but don't know how:

• 1. Load only Credit Card Number (ccNumber) into a ComboBox

• 2. Load the data into the TextBox controls only after the Credit Card loaded earlier has been selected from the ComboBox

Here is a helpful code snippit that I converted to C# from Brandon's post in the Java forum.

return Color.FromArgb(random.Next(256), random.Next(256), random.Next(256));
}[/code2]
