Printing Multiple Pages Problem C++

[bmerlover]

After hours of trying I got it to print and print preview the richtextbox. I've been trying to figure out how to print multiple pages. If the richtextbox contains more than 1 page of data, than it just prints the 1st page and everything else just gets cutoff. If anyone can help me with C++ code, I would really appreciate it. I've looked at a lot of forums before posting this and most of the examples are in C# or VB. I'm thinking the problem lies in the PrintPageEvent although Im not 100% sure. In the meantime, I'm going to try to figure it out.

Using Visual Studio .NET language C++

Here is my code:

private: System::Void menuItem33_Click(System::Object *  sender, System::EventArgs *  e)
{//Print
    printDialog1->AllowSomePages = true;
 
                printDialog1->ShowHelp = true;
 
    printDialog1->Document = printDocument1;
 
System::Windows::Forms::DialogResult result = printDialog1->ShowDialog();
 
if (result == DialogResult::OK)
{
                printDocument1->Print();
}
}
 
private: System::Void printDocument1_PrintPage(System::Object *  sender,System::Drawing::Printing::PrintPageEventArgs *  e)
{    
System::Drawing::Font* currentFont = richTextBox1->Font;
String* text = richTextBox1->Text;
 
System::Drawing::Font* printFont = new System::Drawing::Font(currentFont->FontFamily, currentFont->Size, currentFont->Style);
 
// Draw the content.
e->Graphics->DrawString( text, printFont, System::Drawing::Brushes::Black, 10, 10 );
 
}
 
private: System::Void menuItem34_Click(System::Object *  sender, System::EventArgs *  e)
{//PrintPreview
 
printPreviewDialog1->Document = printDocument1; 
printPreviewDialog1->UseAntiAlias = true;    
 
if (printPreviewDialog1->ShowDialog() == DialogResult::OK)
{
    this->printDocument1->Print();
}
}

Moving this to the .NET forum since it uses the .NET framework.

I FEEL GREAT :). I found the solution. Search the internet deep enough and you will find the solution. Although I had to make changes and debug for another couple of days to make sure it was doing what I wanted it to do. The biggest problem is the Print Page Handler which took a very very long time to fix. This isn't perfect with all the options of printing like you would expect from office but it does print multiple pages, it also recognizes different fonts and different sizes with the exception it does not word wrap on a print.

 
private: System::Void menuItem33_Click(System::Object *  sender, System::EventArgs *  e)
         {//Print
 
            // Allow the user to choose the page range he or she would like to print.
            printDialog1->AllowSomePages = true;
 
            // Show the help button.
            printDialog1->ShowHelp = true;
 
            printString = richTextBox1->Text;
            myReader = new StringReader(printString);
 
            result1 = printDialog1->ShowDialog();
 
            if (result1 == System::Windows::Forms::DialogResult::OK)
            {
                printDocument1->Print();
            }
 
            myReader->Close();
         }
 
private: System::Void printDocument1_PrintPage(System::Object *  sender,System::Drawing::Printing::PrintPageEventArgs *  e)
         {//Print Document Page (Handles both print and print preview)
            System::Drawing::Font* currentFont = richTextBox1->Font;
            System::Drawing::Font* printFont = new System::Drawing::Font(currentFont->FontFamily, currentFont->Size, currentFont->Style);

            while((count < linesPerPage) && (nextChar >= 0))

I forgot to mention u need to add these: So you won't get any errors with the other part of the code.

private: System::Windows::Forms::DialogResult result1;
private: System::Drawing::Font * printFont;
private: String * printString;
private: StringReader* myReader;
