Before this latter call, should I call MemHandleToLocalID to fetch the new (?)
appInfoID to update it in the database?

You need to lock it only if you want to read/write data from this handle.

Hi folks,
im having troubles with the MemHandleResize-function. I use this function in
the following code:
When i call this function 4 times: everthing is OK!
When i call it the fifth time, i get an memErrChunkLocked-error.
I dont know why this happens, and i m getting more and more frustrated
That works
thanks a lot

Don't use MemHandleResize, use DmResizeRecord.

Make sure you don't increase the size of a locked handle.

BTW, I would like MemMgr resize commands to work
similarly to UNIX resize: if the original handle/pointer

Actually MemHandleResize will always succeed when shrinking a handle, but
can fail when growing. You can simply be out of heap space, or if the handle
needs to be relocated and it's locked.
Now you mention the handle value is 0x8000 - which is a good start (the 0x8

Any ideas what would cause MemHandleResize to throw a fatal exception ?
I have confirmed I am resizing it from 46 bytes to 83 bytes. I resize it
several times using the same code and it works fine. The handle is still
the same when it fails.
Here is my resizing code.
StringMemSize += len
izeof(UInt)))==NULL)
TerminateApp();
}

if(MemHandleResize(hBooksIndex,nBooks*sizeof(UInt))==memErrNotEnoughSpace)
TerminateApp();
