Introduction

These simple bits of code will show you how to allow your users to resize a label at runtime. Simple paste this code into an empty form (below the windows generated stuff) and draw a label (called Label1) anywhere onto the form.

Run the program and notice the cursor change when your mouse is over the right side of the label. Click and drag and watch the label resize. This can be used for almost any control and the code can be easily changed to allow width resizing as well.

Dim _mouseDown as boolean = false


Private Sub Label1_MouseMove(ByVal sender As Object, _
  ByVal e As System.Windows.Forms.MouseEventArgs) Handles Label1.MouseMove

   If _mouseDown = True Then
      Label1.Width = e.X
   Else

      If e.X >= Label1.Width - 3 Then
         Label1.Cursor = Cursors.VSplit
      Else
         Label1.Cursor = Me.Cursor
      End If

   End If

End Sub

Private Sub Label1_MouseDown(ByVal sender As Object, _
  ByVal e As System.Windows.Forms.MouseEventArgs) Handles Label1.MouseDown

   _mouseDown = True
   Label1.Cursor = Cursors.VSplit
End Sub

Private Sub Label1_MouseUp(ByVal sender As Object, _
  ByVal e As System.Windows.Forms.MouseEventArgs) Handles Label1.MouseUp

   _mouseDown = False
   Label1.Cursor = Me.Cursor
End Sub

Width and Height, both are resizeable. Krrrishna 6:50 19 Jun '06   Now Width and Height, both are resizable. with this code, bool _mouseDownForWidth = false , _mouseDownForHeight = false; const int _minLength = 35 , _minHeight = 20; private System.Windows.Forms.Button button1; const int _margin = 3; private void button1_mouseDown(object sender, MouseEventArgs e) { if (e.X >= button1.Width - _margin && e.X <= button1.Width + _margin) { _mouseDownForWidth = true; button1.Cursor = Cursors.SizeWE; } if (e.Y >= button1.Height - _margin && e.Y <= button1.Height + _margin) { _mouseDownForHeight = true; button1.Cursor = Cursors.SizeNS; } if (_mouseDownForWidth == true && _mouseDownForHeight == true) { button1.Cursor = Cursors.SizeNWSE; } } private void button1_MouseMove(object sender, MouseEventArgs e) { if (_mouseDownForWidth == true) { button1.Width = (e.X < _minLength ? _minLength : e.X); } if (_mouseDownForHeight == true) { button1.Height = (e.Y < _minHeight ? _minHeight : e.Y); } if (_mouseDownForWidth == false && _mouseDownForHeight == false) { if (e.X >= button1.Width - _margin && e.Y >= button1.Height - _margin) { button1.Cursor = Cursors.SizeNWSE; } else { if (e.X >= button1.Width - _margin) button1.Cursor = Cursors.SizeWE; else { if (e.Y >= button1.Height - _margin) button1.Cursor = Cursors.SizeNS; else button1.Cursor = this.Cursor; } } } } private void button1_MouseUp(object sender, MouseEventArgs e) { _mouseDownForWidth = false; _mouseDownForHeight = false; button1.Cursor = this.Cursor; } "Today is mine, Tomorrow of no ones" Sign In·View Thread·PermaLink code in c#, acharyakrishna1978@yahoo.com 21:43 25 May '06   i m posting this, because it is very usefull, as i hv used it. and i can know its importance. bool _mouseDown = false; const int _minLength = 35; const int _margin = 3; private void label1_MouseDown(object sender, MouseEventArgs e) { if (e.X >= label1.Width - _margin && e.X <= label1.Width + _margin) { _mouseDown = true; label1.Cursor = Cursors.VSplit; } } private void label1_MouseMove(object sender, MouseEventArgs e) { if (_mouseDown == true) { label1.Width = (e.X < _minLength ? _minLength : e.X); } else { if (e.X >= label1.Width - _margin) label1.Cursor = Cursors.VSplit; else label1.Cursor = this.Cursor; } } private void label1_MouseUp(object sender, MouseEventArgs e) { _mouseDown = false; label1.Cursor = this.Cursor; } today is mine, tomorrow of no ones Sign In·View Thread·PermaLink 1.00/5 All I can say is nice!
