    Hi All,When I’m calling CFile::GetStatus with the shared folder in another machine, it’s returning 0 and the last error points to “Access Denied”. I also tried with CFileFind class. The temp folder has full control for the currently logged user.e.gUsing CFileFind classCFileFind f;BOOL b = f.FindFile( “\\\\mysever\\temp” );With CFile classCFileStatus fs;CFile::GetStatus(“\\\\mysever\\temp”,&fs);Sorry if off-topic to this forum.

    I am using VB.net and am puzzling over an issue which cropped up.  I have writen a POS application and am writing a number to a .csv file after each transaction.  The problem I am having is this number is written to the file 3 times for each transaction. It should only write once.  Here is the code I am using:lastbandnum = StartBandNum – 1Trymystreamwriter = File.AppendText(Application.StartupPath & “\saledata\lastband.csv”)mystreamwriter.Write(lastbandnum + &qu

I can get them to work but they don’t look and work as well as I would like them to.What I am after is the look-and-feel of popup menus in Office: a list of menu items, some of which indicate a further set of submenus with a right-facing arrowhead.

    Dears,I have a question regarding the destructor calling mechanism difference between Visual C++ 2005 and Visual C++ 6.0. When i write following code in Visual C++ 6.0 it fails to compile. But when i write it in Visual C++ 2005 it is working well. What could be the reason for this difference? The constructor/destructor of virtual base class is called by “most derived class”. Here the most derived class is TryDerive and it is derived from class NonDerivable. Class NonDerivable is derive

    Hi All, I’ve posted a few times here in regard to a fortran/C++ multi-lang project in VS2008. I’ve tried a few things and have run into the following problem: I have some very old fortran libraries that are calling some PowerStation 4.0 libraries apparently.  I have found the PowerStation libraries and have added them to the project, but they are causing some problems because they contain some duplicate definitions. Is there a way for me to allow the newer libraries (in this case libcmtd.lib

    I remove the datagridviewcomboboxcolumn from the datagridview and dispose it. When I go to dispose of the datatable that is the datasource to the comboboxcolumn an ArgumentOutOfRangeException is thrown from the datagridview. Apparently the datagridview is still handling events for datagridviewcomboboxcells for comoboboxcolumns that have been removed from the datagridview. Any tips on how to prevent this?
