Hi All,

I am using VS2005 VB.NET on a Vista duel core processor machine.

Completely updated from Microsoft.

I have create a communication program that talks to a sensor we build.

The software seems to work fine most of the time. But it keeps crashing randomly.

Here is oneI get.

I know im responding to an old thread here, however I feel I may have part of an answer to this “ApphangB1�nonsense. Iv had this massage with more than just the one App. Im running Vista 32bit on an Intel 3.3 CPU . Without going into detail about my machine, I just want to say it function just fine. Iv noticed that massage (ApphangB1) comes up only when a sound card or graphics or both resources are in use in some way by another program running. By restarting the computer without any of the startup programs loaded under MSCONFIG program, media player or games I might have been playing were able to work again. Its not always an antivirus program that courses this trouble. I hope this helps in some way, after many late nights searching the internet and Microsoft it seem to me nobody really had ideas about what this ApphangB1 is.

gerg did u ever find a solution to your apphangb1 problem if u did i have the same problem so any help would be helpful! u can email me at perez.eber@yahoo.com ty

this msg appeared to me becauseof infinite recursionof the following code :

public long factorial(long number)

if (number <= 1)

return 1;

else

return number * factorial(number - 1);

private void button1_Click(object sender, EventArgs e)

label1.Text = "";

for (long i=50; i> 49; i++ ) // The error is here

label1.Text += i + "! = " + factorial( i ) + "\n";
