I am not sure what you are trying to acheive, but I think it is this:
To set the m_pEdit to the actual variable's address, you can do it when creating the control. Like:

class CMyDialog : public CDialog<br />
{<br />
public:<br />
CXyz m_Xyz;<br />
...<br />
...<br />
};<br />
<br />
CMyDialog::OnInitDialog()<br />
{<br />
m_Xyz.m_pEdit = &m_Edit;// m_Edit is the actual class variable.<br />
}

Now the pointer is set, and there is no need to set it again. Now any function in CXyz can set the edit's text, like:

void CXyz::SetNewText()<br />
{<br />
m_pEdit->SetWindowText("asdf");<br />
}

Your question is not clear, so:
Are you using multi-threading? If no, then learn some multi-threading, and use threads, so the program won't freeze while it is processing.

this is this.

You can put breakpoints in the code and watch the code set the text in the edit. While stepping through the code, you can check if the edit's pointer is valid etc.

this is this.

By using a Memory DC you can prepare the image in memory and then in your WM_PAINT handler you can use BitBlt for a fast copy to the Screen DC. This way you avoid the anoying flicker when working with complex drawings.

That's not always enough to get rif of the flicker. You also need to stop erasing of the background, if the window class has a background brush set.

How to dynamically update an xml file in C++

Dear Experts,

I need some information on dynamic updation of XML file.

Our application asks the user to insert a file by giving the user browsing option.
We want our XML file (which contains the information about the residing files) to be dynamically updated as soon user specifies the path of the inserted file.

The next task is to dynamically update the XML file once the user select the file to be deleted by clicking on the Application UI.

We have to develop the code in C++.

Kindly send across your suggestion, opinion and helpful codes.

Regards,
Mayank Srivastava

You're basically talking about using the XML DOM, I would have thought. If you're not doing this already, how do you read/write your XML files ?

Just do it like you do it with any other file - fopen(), fread(), fwrite(), fclose(). If that's vanilla C++ you want of course.

Hello
I suggest you considder to use a SAX parser. SAX has less memory (and CPU) overhead than DOM.
If you use MSXML, there are plenty of samples at MSDN.

Actually, no. You're telling him to do it in C. I would hope that most people using C++ would never use these functions.

That's about it, it's clumsy, it's ugly and C++ provides a good alternative that is rich in functionality that C file handles cannot offer.
