Do you have troubles adding "cmd " to the actual command typed in your application?
You may also use the system CTR function, for instance

void main()
{
  system("dir");
}

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Why don't you use the FindFirstFile() and FindNextFile() pair?

Cloning Dialogs in VS2005

In a C++ MFC application I have a Main dialog and several child dialogs. Now one of these child dialogs I used the Tabbed Dialog (CTabDialog - which had a main dialog and a dialog for each TAB). This worked greatand it has loads of code associated with the many controls on these tabs.

Now I would like to clone this dialog x2.

What is the best way to try and do this?

I am worried about the IDD/IDC etc in the resource.h file.

I can do global exchange for many items in the code.

Has anyone done this before or suggest the scheme to do this.

Many thanks,

Graham

Why do you need to clone it ? Can't you simply reuse it ? D'Oh! | :doh:

Do you need different functionalities ? If yes, can't you simply make two classes inheriting from the same base class ?

The program controlled a hardware item, using a database and shared library. Now would like to control three items of hardware; which can be done OK. But need three instances of the GUI to control each h/w item.

If was starting the scratch then could design a class for this scheme, but too late now.

For ease and speed, clone the GUI and global change the code behind it.

Hello,

I have a code to open an excel file , add a chart and want to save the chart with the file. Opening file adding chart is done but for saving the file is not saved directly it asks for changes

_Workbook newBook;

newBook.Save(); // this save doesnt work
// i have to write the SaveAs
newBook.SaveAs(COleVariant("d:\\wip4.csv"),vOpt,vOpt,
vOpt,vOpt,vOpt,0,vOpt,vOpt,vOpt,vOpt,vOpt);

How should I save the changes to file ?

Granted, this is vba code - though I'm sure you'll work it out if you've come his far...

---------- 8< ----------------

Sometimes the application displays a messagebox asking if the user wants to continue,
if he/she wants to save a file before closing, or want some other verification from the user.
These messages can be turned off by using this command in a macro :

Application.DisplayAlerts = False
The warningmessages will remain turned off until you enable them again with this command:

Application.DisplayAlerts = True
If you just want to close a workbook without the user being prompted for any confirmations about saving
the workbook you can simply do this:

ActiveWorkbook.Close False ' closes the active workbook without saving any changes

ActiveWorkbook.Close True ' closes the active workbook and saves any changes

How to know which particular user has fired log-off?

I have to make an application which will run on Servers like win 2k3 and Win 2k8. This application will run in system account with multiple instances each for one user logged on the machine. This application is designed to trap logoff event and stop logoff ..do some job and then progress ahead with logff.I am trapping WM_QUERYENDSESSION for this purpose, but unfortunately I donot get any information about which user has loggedd off. I am stuck here as all my applications running trap this message but I need to match them with the user name who actually wants to logg of depending upon that I will have to log off that particular user using his session ID.Please help me out in this.

How about creating a Winlogon notification package? There's also the ISensLogon and ISensLogon2 interfaces, but those also notify after the fact.

I have already created winlogon package which allows me to see which user has logged on as I get the token of explorer in this case. Where as If I try to capture the log off event It is caught when the log off is in progress so I cannot do any thing at that time to abort logoff also by the time the dll gets a call for Logoff the explorer dies and thus I am not able to get which user has logged off. I need to find out which user has logged off.

Hi Friends Iam Very new to STL i want to know what Data Structures are used in MAP<char *,char="" *=""> internally to search or to insert or to delete. can any body let me know this is assignment assigned by my teacher......

Thanks in Advance....

You can download the stl source code from [^]

Since, this is your assignment, you should solve it.
HINT : check map.h and other files included in it.

It can vary from implementation to implementation but I believe that most use a balanced binary tree.

It all depends on the implementation. And anyway, if this is YOUR assignment, assigned by YOUR teacher, then YOU should be doing the work of finding out the answer, not asking someone else to do it - look at the source code.
