Out of memory exception in design time (window form ,C#, .NET framework 1.1)

Paint event of user control is called at design time. Possibly it contains some bug. Can you show your code?

You can set some MessageBoxes in the Paint event handler to get exaclty where it is failing. Do not leave them in the code for later however

Actually, adding MessageBox to Paint event handler can cause endless recursion. In this case it is better to use Trace. Or debug user control Paint handler using second Visual Studio instance.

Trace would not work design time (as well as I know). However MessageBox works and you could just add it until you find the line which causes the problem. What I mean is just set it somewhere and check if it gets shown. If yes - move it further down, otherwise up and so on until the line is identified. Something like a binary search :-)

Trace is always executed when code runs. However, Visual Studio which hosts user control doesn't show trace output from code executed in this control. This can be done using DebugView utility from www.sysinternals.com.

This is my code -

//Override paint method to change forecolor of TextBox when it is in disable mode.



Constructor 1()

{

 this.SetStyle( ControlStyles.UserPaint, true);// I called this in constructors of the class.

}


Constructor 1()

{

 this.SetStyle( ControlStyles.UserPaint, true);// I called this in constructors of the class.

}




protected override void OnPaint(PaintEventArgs e)
            {
                  if(this.Enabled==false)
                  {
                        
                        this.SetStyle( ControlStyles.UserPaint, true);
                        SolidBrush drawBrush = new SolidBrush( color.black );
                        e.Graphics.DrawString( Text, Font, drawBrush, 1f, 1f );
                        this.BackColor=System.Drawing.SystemColors.Control;
                        
                  }
                  else if(this.Enabled==true)
                  {
                        this.SetStyle(ControlStyles.UserPaint,false);
                        SolidBrush drawBrush = new SolidBrush( ForeColor );
                        e.Graphics.DrawString( Text, Font, drawBrush, 1f, 1f );
                                                //base.Enter(e);
                        //base.OnLeave(e);
                        
                         base.Refresh();
                        //base.OnPaint(e);
                  }
                      
                                this.SetStyle(ControlStyles.UserPaint,true);
                      base.OnPaint(e);
                    

Without questioner's feedback, I suggest split.
