You are first allocated a buffer on the heap, of size 50. You store the pointer in strFile. Then you do a CString::GetBuffer on a CString object, and overwrite the value in strFile with this new value, thus creating a storage leak.
Also, there is no need for the parameter to GetBuffer.
When you call delete, which frees the CString buffer out
from under the CString, then the CString destructor sees a completely screwed-up heap.
LPTSTR strFile = str.GetBuffer();
std::ofstream myfile;
myfile.open ("d:\\example.txt");
myfile << strFile ;
myfile.close() ;

You're misusing the return value of GetBuffer(). GetBuffer() returns a pointer to the buffer that the CString manages, you must not delete that pointer.

My problem is to provide multilanguage support for my application.
i,e i have to show the Dialog based application in English when the user clicks english from the menu, or in French when he clicks French from the menu.
when the user changes the language the application should change its whole display according to user choice

in dialog based application by clicking a button if i want to open a another window how it will b possible???is there any function for that which can b used there..
thanks

You can use
Create an object to the class and use 'DoModal()'
or
Create an dialog pointer and use ShowWindow(SW_SHOW)
DoModal() will disallow any actions in parent dialog untill the new dialog is closed

Is the window (dialog or window) part of your application? or and external application
For the dialog
You can call DoModal function of the dialog object
For SDI, MDI or or other type of windows, You can call ShowWindow function to show the dialog
It should be handled inside the message handler of the button
If an external application, you can Make use of CreateProcess API.

if its another dialog then call it using DoModal() function of the instance of the dialog.
Eg MyDialog dlg;
dlg.DoModal();
if its a window then call the ShowWindow() method
eg ShowWindow(this->m_hWnd,SW_SHOW);

can u help me when i use this function i got the error
"
C:\myproject\newartz\newartzDlg.cpp(204) : error C2660: 'ShowWindow' : function does not take 2 parameters"
Sorry to bother u pls help me out
eg ShowWindow(this->m_hWnd,SW_SHOW);

oh just remove the this->m_hWnd argumtent ok
Get the window handle that you want to display and'
then call the showWindow function.
Eg CWnd *p = AfxGetMainWnd();
p->ShowWindow(SW_SHOW);

You can use CreateIndirect or CreateDialogParamor DoModal()
How do you open?

Hello, I have a single dialog with a custom control which is based on the CWnd class. From method in the custom control, I need to access a variable from the dialog's class. How would I need to make this call to say a getValue() method?
FYI, I am using VC6.

Use GetParent(). This will provide you with a pointer with which you can call getValue().
Somethings seem HARD to do, until we know how to do them.

Im not sure, whether the GetParent call from a COM control will work out.
Anyway, call GetParent(), if you get a valid parent handler, type cast it to your Dialog class' pointer. using dynamic_cast will be safe for this. then you can call the public interfaces.
You may have to use the header file and other stuffs of dialog class in the control class.

you should not directly access the members of the dialog using the pointer, in which case your custom control no more is a reuseable custom control. You should define user defined message handlers in target window and then try to set/get anything using it.

You can post this on my CP profile instead of posting here  can't you display original image and by using a simple encryption function, convert the bitmap bits to to encrypted format and then save? I'm not sure whether I'm talking about your problem

Yes I shall...
But today im a bit busy.
Seems you can so some stuffs with showing and saving an image. that's quite simple. you will get lot of information from the web itself.
On reading and writing to file, the real logic occurs.
You can make use of GetBitmapBits and Set bitmap bits. or directly modifying the bitmap buffer wtih your XOR logic.
ok try your level best.
