You may also like to do it:
Create it in heap. Delete it.
<br />
Display* pDisp = new Display;<br />
pDisp->Count=10;<br />
delete pDisp;<br />

If you have an object of type Display, then any data in the Display object
will be deleted when the object is destroyed, either automatically by
going out of scope (for automatic variables) or by freeing a dynamically
allocated object.

Hi,
I want the project to execute in the system where VC++ is not installed.When i tried to execute my project in 2 systems where there is no VC++, in one system it worked with or without dlls( MFC42D.dll,MFCO42D.dll, MSVCRTD.dll)but in another system first dialog box opens, when i press "ok button" in that dialog box it has to close current dialog box and open next dialog box but the user interface is closing without showing any error.
Help me to know why it is happening.Project is working fine in the system where VC++ is loaded.
Thanks

First step is to make a "Release" build. Your exe is sreaminf for debug dlls.
On VC6 you can make a static link to MFC, so all dependencies are in the bigger exe.

I have made release build and also static library then also problem exists

The failure may or may not be anything to do with the presence or otherwise of VC++. You can use the depends tools from Microsoft ( shipped with VC++6 Pro ) to determine your .exe's static requirement for Dlls but this is not the problem in your case.
You need to add some diagnostic logging/tracing to your application and possibly a crash handler ( There are good examples on CP ) to determine why your app is closing down unexpectedly. It should be able to report the causal error before disappearing even if it's a really nasty fatal problem.
The good news is that it is isn't taking down the clients machine on its way out. The bad news is you may need a lot of cooperation from the client to solve the problem.
Good luck.
Nothing is exactly what it seems but everything with seems can be unpicked.

Could u plz tell me the link where i can find Crash handler examples and what does CP means.
thanks

CP is local short hand for Code Project (this site) and you can find lots of useful articles on Crash handling, Error handling, Exception handling, and logging and reporting in the C++/MFC and other sections of the Articles pages on this site. It's probably best if you look yourself for the ones most relevant to what you're doing and the technologies you're familiar with. Failing that a web search for the name 'John Robbins' will get you more information on debugging than you could use ever reasonably use. Enjoy.

As your application seems to start correctly (you don't have an error message that is displayed immediately when you launch the app), I suppose that it is not a deployment issue. So, as Matthew stated, it has probably nothing to do with the fact that VC is installed or not. Anyway, it is always better to distribute the release version of your executable.
Do you use any ActiveX ? That could be the problem: if you try to use an ActiveX that is not registered, you'll have this kind of problem.
If that's not the case, you'll have to dig into more details (like Matthew suggested).

HI,
Am using MSComm, this could be the problem.
Thanks

Try to register it before lauching your application and see what happens.

Sorry i didn't get what u r saying

Copy the activeX MSComm32.ocx in the windows\system32 folder (take it from there on your own computer) and use regsvr32 to register it.
Click on Start -> run and there type "regsvr32 MSComm32.ocx".

Hi,
I tried above method, it worked for windows 2000 but in XP the problem still exists.
What i did is:
1) i copied the file MSComm32.ocx in my system(mine is windows 2000)and placed in XP m/c at location c:\windows\system32 problem didn't get resolved.
when i did above step in windows 2000 it worked(i tried in 2 systems)
Except mine in all other systems i couldn't register(Click on Start -> run and there type "regsvr32 MSComm32.ocx". )
Thanks

What was the error message ?
|
|
|
|

Hi,
The error message was
"Cannot find the file 'regsvr'(or one of its components).Make sure the path and the file name are correct and that all required libraries are available"
The systems which got this error doesn't have VC++ installed. I had placed MSCOMM32 at windows\system32\mscomm32.ocx or winnt\system32\mscomm32.ocx
Thanks

Type regsvr32 not regsvr.
|

Hi,
Sorry i was giving the wrong command(regsvr MSComm32.ocx).
When i gave regsvr32 MSComm32.ocx it is working fine.
Thanks

Hi,
Its working fine in all the systems, as i had not registered properly it was creating problem.
Thanks a lot.

Hi,
One more Q, in one of the system mscomm32 was existing but created in 1997(when i saw in it properties) when i executed my project it was not working, when i replaced with the mscomm32 which was created in 1998 it started working.Am curious to know why it is so.
Thanks

This has absolutely nothing to do with C++. Read the forum guidelines.
