Find something that interests you and then try to learn all you can about it. "Improving" VC++ and MFC is a very open field and you will get lost quickly.

Why is common sense not common?

Never argue with an idiot. They will drag you down to their level where they are an expert.

Agree.
A better idea is to find a project and finish it. Like design a simple calculator?

One of the things that I used to do when I had time to kill was to pick a function, or an API, and write a whole program around it. I learned a lot this way.

Got to the MFC src file (..\Microsoft Visual Studio\VC98\MFC\SRC) it has lot of good code and will give you internal details about each thing.

Does anyone know of any tutorial tools that might be helpful in getting up to speed with VC 8?

Time past, whenever MS came out with a new version of VC, they'd produce a CD for those who might need a little help getting acquainted with the product.

I've just barely become acquainted with VC 7, and now VC 8 has me stumbling all over the place.

Thanks.

Hi all,

I am writing a VC++6.0 application. I need to read from a text file and display the file content in an Edit Box. I use the following codes:

CEdit m_fileContent;
CFile pFile;
m_fileContent.SetWindowText(""); //clear
pFile.open(.....);
int length = pFile.GetLength();
CString* strContent = new CString("");
pFile.Read(strContent->GetBuffer(0),length);
m_fileContent.SetWindowText(strContent->GetBuffer(0)); //update file content
strContent->ReleaseBuffer(0);
delete strContent;
pFile.Close();

Now the problem is: When I first opened a file, it's fine. But When I opened a second file, if the length of the first file is longer than that of the second file, the content is not cleared. Any ideas? thanks,

Gavin

CEdit m_fileContent;
CFile pFile;
m_fileContent.SetWindowText(""); //clear
pFile.open(.....);
int length = pFile.GetLength();
//CString* strContent = new CString("");		// why are you putting CString on the heap?  This is a waste.
CString strContent = _T("");
pFile.Read(strContent.GetBuffer(0),length);
strContent.ReleaseBuffer();
m_fileContent.SetWindowText(strContent); //update file content
//strContent->ReleaseBuffer(0);	// need to do this before using the buffer anywhere
//delete strContent;		// not needed
pFile.Close();

How the application knows whether the machine is Laptop or Desktop?????

Try:

CString strContent;
pFile.Read(strContent.GetBuffer(length), length);
strContent.ReleaseBuffer();
pFile.Close();
m_fileContent.SetWindowText(strContent);
