Hi everyone!

I have a problem with this portion of code. AutoHotkey_L often crashes with this part of code!
It saves the clipboard to a file

could you do a sleep between filedelete and fileappend?
see if that helps

No need for filedelete, see docs: a fileappend, %clipboardall% automatically deletes the file if present.

Where exactly does it crash?

I think it crashes with FileAppend and may be with big contents.
If I save the clipboard with simple plain text, it works fine but if I try to save a selection in Word (text, formula, table), it crashes!

For more details, I use this part of code to store formulas and paste them with Regex hotstrings

I am able to reproduce the problem copying an equation from Word

It seems that Office programs do not play well with AHK in this regard. I think I found a workaround, though:



Try that instead. Saving the entire clipboard to a variable first seems to work better.

@Rapte_Of_Suzaku: Sorry for my English but you mean you have the same problem?! I'm trying your solution.

All I meant was: I successfully got the same problem to happen on my computer. If I can't first get the problem to happen on my computer, it is harder to find the solution.

I tried your solution, it still crashes but less!
I think this is a problem with Word because with Writer (open office) it never crashes!
Even if it works with Writer, I would it to work also with Word!

Edit: With Writer I save a clipboard with formula, table, graphics and pictures and no problems!

You might consider posting this in the bug report section now. It may be Word's fault, but it feels like a bug to have AHK crash.

Which Office version do you use?

It seems to work fine for me (Office 2003SP3)

The solution of Rapte_Of_Suzaku reduce the crash.

It seems that AutoHotkey (any version) assumes that GetClipboardData(format) will return a handle to a block of memory. This naive approach works for the most part since GlobalSize() fails when it is given an invalid handle, causing unsupported formats to be skipped over. During my testing, the crashes occurred when trying to call GlobalSize() with a handle returned by GetClipboardData(CF_ENHMETAFILE). Sometimes it crashed, sometimes it merely returned error 6 (ERROR_INVALID_HANDLE).

Reading Standard Clipboard Formats, it appears that at least the following formats should not be interpreted as memory handles: CF_BITMAP, CF_ENHMETAFILE and (probably) CF_DSPENHMETAFILE. It might be sufficient to simply skip these formats. I need to review the other uses of ClipboardAll before I attempt a bug-fix.

I've moved the thread to Bug Reports.
