C++ text editor .NET

**MB1** · 02-23-2006

I want a text editor that can open a file in the same format the file is saved in. Everything works except for the editor opening the file in the same format that the file was saved in.

Suggestions?

Here's the code for the Save and Open buttons. I assume that is
the problem.

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 * Delimiter1 = sr->ReadLine();
	 if(Delimiter1 = "$$")
                        String * fontName = sr->ReadLine();
	else
                        sr->Close();
	 String * Delimiter2 = sr->ReadLine();
	 if(Delimiter2 = ";")
	     int * fontSize = sr->ReadLine();
	else
	      sr->Close();
	String * Delimiter3 = sr->ReadLine();
	if(Delimiter3 = "$$")
	{
	     String * s = sr->ReadToEnd();
                     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->WriteLine("$$");
	sw->WriteLine(textBox1->Font->Name);
	sw->WriteLine(";");
	sw->WriteLine(textBox1->Font->Size);
	sw->WriteLine("$$");
	sw->WriteLine(textBox1->Text);
	sw->Flush();
	sw->Close();
	}
 }

Hi,

This is a C++ forum. What you posted is not C++, so you may want to seek out another forum.

the file needs to have formatting instructions at the beginning of the file. Most text files do not have that information. For example, files created by MS-Word have all the formatting instructions embedded in the file, which is why you see a bunch of funny-looking bytes when the file is read by a text editor such as Notepad.exe.

sure looks like c++ to me

although there appears to be a few bugs.

It's Visual C++ actually. (Maybe not too good though.)

I'm using notepad to test the save info. Notepad shows:

$$
arial
;
12
$$
My text that I have saved to a file.

So I know the info is being saved properly. When I open the text in my editor, the text opens in the editors default format.

I got confused by:

Code:

    private: System::Void 
...
...
}

It's generally called Managed C++. Visual C++ usually refers to the IDE that lets you write managed or unmanaged C++ code.

So, the code you posted is not anything you wrote, but a macro that the compiler uses on the Save and Open menu items??? If that is true, then 7stud is right -- wrong forum. you need to go on Microsoft's development forums and ask them why it doesn't work.

I wrote all of the code except the two lines that start:

private: System::Void OpenBtn_Click....

and

private: System::Void SaveBtn_Click.....

These two lines are what the compiler writes and then I write the rest of the code as to what I want the Open and Save buttons to do.

I think the open button is where I messed up.
