Access violation

1. Your project does NOT link bacause of the settings "Use MFC in a Static Library". So I had to chaged it to use in Shared DLL.
2. Set a break point in the begin of the
XMLNode XMLNode::openFileHelper(const char *lpszXML, LPCTSTR tag) method, then start debugger to debug your application - you will see that this method "silently" calls exit 255;
Note, that it is a very serious mistake to use exit operator in any MFC application! To exit (at this stage, when mainframe window already exists) you should PostMessage/SendMessage a WM_CLOSE message to your mainframe window!

Hi VictorN. I am using someone else code of the XMLParse.cpp. But I see what you mean of the exit(255);. I have make a test by commented this line, but it seems that still having the same problem where when the window is opened, and then I click on other windows twice, the application window will disappear and closes.

Also, the problem happens when I have arguments passed to it when it is launched. If without the arguments, there is no such a problem.

It is up to you to investigate why and when your XMLNode XMLNode::openFileHelper method or/and LPTSTR fromXMLString global function call exit.
I only wonder why are you using these silly ways to exit the application and why are you doing it silently (why not to display a simple AfxMessageBox with some meaningful message about the problem?)!

This is not my file, I got it from somewhere else. So I never thought that it will create any problem and never suspect of the functionality of the code.

I have try to get rid of the exit command in this file, but it seems there is still have the problem. I am just thinking this might not be the only reason that creates the problem. But anyway, thanks for your help and I will try to find the problem. Thanks again.

You are welcome!

PS. There are some other problems in your project. You could see some "Warnings" messages when compiling your application... :cool:

Unfortunately, after trying hard to debug the problem, I still having the problem.

VictorN, although I have look through the exit(255) for the whole project and make sure there is no silent quit, but the problem is still there.

I really reckon the problem is when I pass the arguments because the application only closes itself when there is argument sent to it before the launching. It is fine when there is none argument passing to it.

Please give me a hand on this.... I would be the most appreciate it.

Since you don't provide any useful information it is impossible to help you more...
The only thing is clear - you process or/and use the command line parameters the wrong way.
Again: you should debug your code step by step incuding the stepping in (Use F11 to do it) each your method from the very begin (from the ctor/create/initialize of every class and so on...)

I have already attached my whole project in the thread and clear stated the problem I am having. It's not that I am not trying to debug it myself and just asking for help without trying it. But I couldn't fix it and I am really just learning from scratch about programming. I just genuinely need some helps.
Anyway, thanks.
