Slow Debug of C++ code - C# / C Sharp

Eric Robert

Hi,

I am writing a C# application that uses a C++ unmanaged DLL. When I turn the
unmanaged debug option ON, the application is much slower to start and the
unmanaged code is very slow to debug.

Is it normal?

Here is more information and a sample program. Writing it, I even found some
kind of weird behavior. The call to OutputDebugStri ng in the DLL doesn't
show if "Enable Unmanaged Debugging" is not set to True.

MySQL ODBC 3.51 driver Very Slow!

What makes this code slow

by: dbuchanan | last post by:

This code resets a form with two cbo's (comboBoxes) and one datagrid. The first cbo (cboSelection) selects a main table and filters the second cbo. The second cbo (cboView) selects the secondary table which determine the dataAdapter used to fill the dataGrid. Both cbo's are populated by filling dataAdapters. This code just empty's the datagrid, cbo's and dataset so the user can start over to view another set of data. \\

slow debugging visual studio 6.0

by: yuanliu1 | last post by:

Hi, I am debugging my code of visual c++ 6.0. I found it is extremely slow to run after the code is compiled as "debug" mode and OK as "release mode", I would say the difference is around 10x. But I am developing and mainly working on "debug" mode, it is very clumsy to wait for 10 mins for just one run. I did a check and I suppose it is related to the heap check in "debug" mode, so I am wondering if I can turn it off in visual c++ 6.0...
