Displaying the file without scrolling - document class, Visual Basic Programming

Displaying the file Without Scrolling:

To display a file follow the steps as shown below:

1. Generate a SDI application.

2. Type the coding as shown in the Serialize else part. The CArchive objects are used for writing or for retrieving the file.

3. Generate a global string m_pdata in the document class. To generate the global data click on the ClassView tabpage.

Enlarge the tree control of classes.

Select the CStoreDoc class.

Right click and choose the add member variable.

Specify the type as char and the variable name as *m_pdata

The GetFile() function of the CArchive is used for selecting the file to be displayed.

The GetLength() returns the size of the file.

4. Allocate the memory to the string m_pdata by using the new operator.

5. The Read function of CArchive stores the ncount characters of the file to be displayed in the string of m_pdata.

6. The string m_pdata is displayed by using AfxMessageBox.

7. The dynamically allocated memory is improved by using the delete function.

8. Construct and execute the project.

9. Choose a file and open the menu item.

10. Choose a file.

11. The contents will be displayed in the message box.

void CStoreDoc::Serialize(CArchive& ar)

{

if (ar.IsStoring())

{

}

else

{

unsigned int ncount = ar.GetFile()->GetLength();

m_pdata= new char[ncount];

ar.Read(m_pdata,ncount);

AfxMessageBox(m_pdata);

delete [] m_pdata;

}

}
