I find this error to be very curious, I have a data window. My intention is to create a basic add, edit, delete app and the code in my delete button contains the following code:

Self:Delete()

I get a processor stack error. While debugging I see the delete code execute over and over until I get the error. I don't understand why the code executes over nd over, and the delete never occurs!

Any ideas...thank you,

Most likely you are calling the method in a **recursive loop**.

Need better help?

Go the X# forum at www.xsharp.eu and upload and a complete minimal AEF,
with all related files, which duplicates the issue.

I suggest you always provide the VO version, Window version, etc.

Also, if a post helps you, then say so. It's a good for others to see if
the issue is resolved in case they run into the same problem.

David,
Is the method that contains this code also called Delete ?
In that case:
- you do not need that method at all
- or you change the code to SUPER:Delete()

David,

You are confusing SUPER with OWNER

SUPER is the DataWindow class from which your class inherits.
OWNER is the Shellwindow class (if your window is inside a shellwindow)

Robert it worked, But I don't understand...Self is my datawindow, super gets me to the app level, as I under stand this, which is why I don't understand. A more detailed explanation would be GREATLY appreciated.

Oh yes...So then similarly my add code should be IF super:Append() = TRUE instead of IF Self:Append() = TRUE which is what I have now
This was also confusing because Self:Append() worked and Self:Delete did not. Thanks again

The problem with the Delete() method was that you named the method that
was calling Delete(), also "Delete", something like that:

METHOD Delete() CLASS ...
SELF:Delete()

so that code in line 2 was calling the same method itself again and
again. Using SUPER instead of SELF, you tell the compiler that you want
to call the same named method that is called one level lower in the
class hierarchy, so there's no recursive call anymore.

It's the same with Append(), if you were calling it from a same named
method like this:

METHOD Append() CLASS ...
SELF:Delete() // recursive call

then you woudl have again the same problem.

Btw, are you really using VO 1.0 and Win 3.1 (in a virtual machine) as
you mentioned in one of your previous posts?
