Text Editor

**MB1** · 12-12-2005

I am finishing up my text editor that saves the font and size and then displays the text according to the saved info. So far I have the program writing the font name and size then $$ to mark the end of my font info and the beginning of the saved text.

First problem. Everytime I save the file it writes the font and size again. Suggestions?

Second problem. When I display the file I want only the text to show. More suggestions?

Code:

private: System::Void OpenBtn_Click(System::Object *  sender, System::EventArgs *  e)
			 {
	OpenFileDialog * fd = new OpenFileDialog();
	if(fd->ShowDialog() == DialogResult::OK)
	{
	FileStream * fs = new FileStream(fd->FileName,  FileMode::Open);
	StreamReader * sr = new StreamReader(fs);
	String * s = sr->ReadLine();
	 textBox1->Text = s;
	sr->Close();
	}
    }

	private: System::Void SaveBtn_Click(System::Object *  sender, System::EventArgs *  e)
			 {
				SaveFileDialog * fd = new SaveFileDialog();
          if(fd->ShowDialog() == DialogResult::OK)
              {
	FileStream * fs = new FileStream(fd->FileName, FileMode::OpenOrCreate);
	StreamWriter * sw = new StreamWriter(fs);
	sw->Write(textBox1->Font->Name);
	sw->Write(textBox1->Font->Size);
	sw->Write("$$");
	sw->WriteLine(textBox1->Text);
	sw->Flush();
	sw->Close();
           }
      }

private: System::Void FontBtn_Click(System::Object *  sender,      System::EventArgs *  e)
			 {
         FontDialog* fd = new FontDialog();
         fd->Font = FontLine;
				
          if(fd->ShowDialog() == DialogResult::OK)
	{
	 FontLine = fd->Font;
	 textBox1->Font = FontLine;
	 }
          }
     };
}

Can't you just save the Font and size in the registry, and then save the user data as text?

yes - you can :]
RegCreateKeyEx
in the left hand pane there are all of the other registry functions that you'll need for querying / closing the registry keys as needed.

Can't save to the registry. The information is supposed to be saved to a file and when the file is open, my text editor will read the font name and size then display as such.

Was actually trying to use fontfamily.

It looks like you are using .NET to code this, so why not make the file format be XML, since there are classes in the Framework for reading XML format files. Then you could do something like:

Code:

<File>
<Font>Times New Roman</Font>
<FontSize>16</FontSize>
<Body>Hello World!</Body>
</File>

My file shows the font and size then ##

like this->Microsoft Sans Serif8.25## testing one two three

When I open the file, text editor is supposed to read the saved format of Microsoft Sans Serif and font size 8.25 then output "testing one two three" in that font and size.

I need the code to put in my open button click handler so that this happens.

Your <font> sounds easy. I can't do it that way.

Doesn't the String class have a split method, i.e. you could split the text from the ReadLine call using "##" as the characters to split on. But how do you know where the Font ends and the Size begins?
