if you want to enter a string on the editbox(I think you used of editbox) you can use of SetWindowText.

Thanks. It works. But since it is a string, while modifying some other edit filed (number) and updatedata(TRUE), the error message "Please enter a number" is displayed. Please let me know a way to avaoid this error / catch this error message.

Thanks

Thanks

string value (NA) and double value.

I think you need to use SetWindowText and GetWindowText, instead of using control variable as double. Or simply how can string value like "NA" be stored in double?

AfxTextFloatFormat is called by DDX_Text where this message is generated.

I can say another option. Add a member function same as UpdateData(BOOL bSaveAndValidate = TRUE). Remove DDX_Text entry in the DoDataExchange. Convert the window text to double in the new UpdateData if the BOOL bSaveAndValidate is TRUE (if it is NA you can check it also) and do vice versa if FALSE. Also call the CDialog::UpdateData(bSaveAndValidate) so that other control variables will not be affected.

Hope it is OK.

That could be a source of your problem. Use SetWindowText() instead of UpdateData().

Prevent who ?

You could open the file with CFile and use one of the flag to prevent other processed to access it.

You would need to set this restriction at the OS level.

Create a service which opens an exclusive handle to the file. This will prevent copying and deleting.

Using the mfc CFile class

CString file_name = _T("C:\\AnotherFile");

CFile f;

f.Open( file_name, CFile::modeRead | CFile::shareExclusive );

while(1)
Sleep(1000);

Event Log Question

Hi all,

I would like to know wheter there is any way (using code) in which I can get hold of the system log, in terms of, when Windows has finished downloading updates and needs to restart. See the reason I'm asking is because some of our computer are never used by users, but still need security updates, and in the light that after every update Windows needs a restart, there will be no user to do so. Any suggestion ??

Many Thanks

Eventhough by default the file for "Application" events comes in the above mentioed path, it can be changed by changing the values in registy. Search the registry for value "C:\Windows\system32\config\AppEvent.Evt"
