Stack Over flow exception for long code in picture box paint.

Hany Metry 41

I have a long code in picture paint of picture box, so when I run the application, I got a message Stack Over flow exception as per attached photo.

How I can divide the code into two or more subroutine.

The code manly is drawings with many conditions.

The code is in VB.net

Maybe there are issues that cannot be solved just by dividing the code.

There is a bug in your code.
There could be 10 millions of lines in Paint event, if there is no bug, it will work...

Hi,

If we divide the code the problem will be solved and I am sure from that.
The problem is "e" how we can solve the problem of "e"

Hi
Sorry, I tried to divide the picture paint code into additional subroutine but the problem still exist.
I have not problem in my code!!!!!
I have many declaration by Dim format, Do you think, if I make the declaration in the module the problem will be solved?

At some point you can also show the code of PictureBox1_Paint and other procedures that cause the issue.

Hi Bruce

When I try to divide the picturebox1 paint to additional subroutine by writing the following code in the module

Friend e As System.Windows.Forms.PaintEventArgs

Initialization exception happened.

And when I make my program divided into two programs, my problem is solved and I have not stack over flow exception.

So stack over flow exception happened because long code in picture box paint.

Kind Regards,

Stackoverflows are not cause by code length. And breaking up the code (which is typically a good idea for readability and maintenance) will have no effect.

Typically cause is a non terminating recursive call. Review your stack trace.

in your posted vs image, it is the call stack window.

Hi,

Problem history

First of all when the declaration is written between codes, the stack over flow for picture box paint start when load the program (before input any data) but after make the declaration at start of picture box code and make "enable just my code" in debug option, the stack over flow happened during input data when the code refresh picture box1 is run.
When the declaration is written at module, the stack over flow for picture box1 paint, start when load the program (before input any data).
The code is long code and the declaration also is long.

Before increasing the code length for picture box 1 paint by 20%, I have not any problem in my code.
usually for any Private Sub when I got stack over flow exception, I divide the code into two or more subroutine and the problem is solved

The planning of picture box paint code is to increase the code by 50% and I don't know what will be happened.

When I try to divide the code into two subroutine, the second one give stack over flow exception, but I did not try to divide the code into three subroutine.

How I can solve the problem

Kind Regards,

Hi,

The problem happened during load the program and I don't know how to make stack trace.

The problem is your code is recursing. you will need to fix the bug. breaking it up will not help. looking at the stack trace should help find your bug.
