Runtime 28 - Out of stack space

[Oggy]

Hi

I have written a macro in Excel 2003 and everything seems to works as
exspected, but accasionly i get the following error message

Runtime error 28 Out of stack space


Does anyone know what it is and is there a code i can add to my macro
to fix it?

Thanks

Does the macro call itself ?

If so, I'd guess that it doesn't get to a point where it meets the exit
criteria.

Regards

Trevor

There are 2 kinds of memory that you need to understand when you program. The
first is the heap. The heap is where a program stores all of the memeory that
needs to persist for as long as the program is active. Global and Static
variables land in the heap. The stack on the other hand stores the variables
that are volatile and which end with the function or procedure that declares
them. The biggest culpret for running our of stack is a recursive function
without a valid stop. In this case the procedure declares a variable on the
stack and then calls itself again. When it is called it declares another
variable on the stack on top of the other variabes that are already there.
This happens recursively and before too long the stack is full. Normally this
generates a Stack Overflow. Out of stack space is new too me but as a guess
it would be generally the same problem. Take a look for a sub or function
that could be called recursively (event code is a good culprete for recursive
code). Post the code that seems to be generating the error and we can take a
look at it for you.

That article says it only applies to XL 5.0. Is it still a proble in 2003
Version 11

My code opens a userform, which a user fills out and then on the
comand button it takes the infomation and places it in a spreadsheet
and the opens another userform. This happens three times and then goes
back to the menu.

The error happened after about 30 loops

Thanks for all your help

Are you hiding the user form or are you unloading it. Unloading the form will
clear out the stack. Other than that post your code an dmaybe we will be able
to spot something.

Hi Jim

I have looked through the code and the only thing i can think of is
the code to check the screen resolution and make the userforms fill
the screen may be the problem. Below is the code to one of the loops
where it opened userform 12, then 13, then 14, then 15 from a menu
userform 16. This code is to show the userforms only, there is more
code to the userforms themselves.

Any coments or alternitive ideas would be grafully recieved

Many thanks
