Hi I'm having appcation error, the memory xxxx to xxx canot be "read" or "write" error while using these kind of module.

The first print is Ok, but following report will be cause the error.

However I've tried many ways:
1) Put declare of all declaration inside the sub
2) Directly output to frmpreview without going into frmPrint
3) Print directly without going into frmPrint
4) set crrep = nothing after use (cause hangs directly)
5) etc

The cr I'm using it's 9.0 sp6, vb6.0 sp6, ado 2.8. I wonder any solution for my problem? Quite urgent for this, cause the program is done and I only have this major printing problem.

Thank you very much~
