Hi,
Is there any way to disable the default error messages using ADO & MFC in the try catch structure ? Because now i receive two (2) error dialog messages. One from the OLEDB and one that belongs to the application custom error.

Yes.
But there are drawbacks[^] too...

#pragma data_seg("Shared")
volatile LONG g_lApplicationInstances = 0;
#pragma data_seg()
This will help you in creating a shared section . This variable will be shared by all the instances . So what you have to do now is to have control of the variable g_lApplicationInstances that is shared
You can use interlockexchangeAdd
InterlockedExchangeAdd((PLONG) &g_lApplicationInstances, -1);
Vision is Always important and so is your ATTITUDE.

You also need the following line:
#pragma comment(linker, "/SECTION:Shared,RWS")
Without it I believe the segment will not actually be shared.
Steve

|

Yes you are right.
This will enable you to modify the variable and make the shared variable read write etc,

if u use cfile class to open a file. some options are available on the Open function of openflag parameter. like that CFile::shareDenyRead, CFile::shareDenyWrite and CFile::shareExclusive. for more details review msdn cfile constructor help.
Have A Nice Day!

but it is already opened by another program in CFile::shareExclusive mode,that is currently running in the system.so is there any way to open
that perticular file in my program at the same time?

yes it is possible...but only from kernel-mode with a device-driver. You must use the IoCreateFile call to open a handle to the file - this bypasses the security/access checks so you must never use this technique on a 'real' system!

I wanna how to develop window app with c. petzold book programming windows also use vc resource editor .
corresponding question:Is the resource compiler a must for window programming? that is ,to develop window app, must I have c compiler, linker, resource compiler?
|
|
|
|
|
i don't think you need the resource compier as a "must" for windoww programming.
you can always create your windows at runtime, but that's very expensive efforts

i think that this question relates more to the CxImage article, so you should ask this in the article's message board[^] at the bottom of the article...
