Some quote from the MSDN[^] site: "The KeyPress event is not raised by noncharacter keys; however, the noncharacter keys do raise the KeyDown and KeyUp events." You should do Keydown's instead of ProcessCmdKey, that's what you are doing anyways...

Just do it on the .NET way.

You could write your switch statement on OnKeyDown method: private void _yourcontrol__KeyDown(object sender, System.Windows.Forms.KeyEventArgs e) { switch(e.KeyCode) { case Key.Down: //Do something ... } ... } Beside, embedding System const's in your code is not a nice thing to do. Microsoft could just change the values and your code will go to the outerspace.:laugh: ps.: Some words from MSDN[^]: Notes to Inheritors When overriding the ProcessCmdKey method in a derived class, a control should return true to indicate that it has processed the key. For keys that are not processed by the control, the result of calling the base class's ProcessCmdKey method should be returned. Controls will seldom, if ever, need to override this method. Diego Valdevino

You've said your Form has a huge number of controls on it. Maybe you should do double buffer on the controls too.

You could just override the DrawNode method, and based on a custom treenode tag or property, e.g IsInvisible, decide if the node must be drawn. Diego Valdevino.

I am creating a custom draw treeview with level 0 treenodes draw by the code below. I want to paint the entire node row, including behind the PlusMinus button with a color of choice. The problem happens with my code running after the PlusMinus button is painted,thus erasing it. Is there some event fired before OnDrawNode painting the "+" that i am missing and should override? Setting a breakpoint on the begining of OnDrawNode and seeing the control, shows me the "+" is already painted. protected override void OnDrawNode(DrawTreeNodeEventArgs e){ if (e.Node.Level == 0){ Rectangle nodeRegion = new Rectangle(ClientRectangle.X, e.Node.Bounds.Y, ClientRectangle.Width, e.Node.Bounds.Height); SolidBrush nodeBackColor = new SolidBrush(Color.BlanchedAlmond); SolidBrush nodeForeColor = new SolidBrush(Color.Black); Font nodeFont = (e.Node.NodeFont == null) ? this.Font : e.Node.NodeFont; e.Graphics.FillRectangle(nodeBackColor, nodeRegion); // PROBLEM e.Graphics.DrawString(e.Node.Text.Trim(), nodeFont, nodeForeColor, e.Node.Bounds.Location); } else{ e.DrawDefault = true; } base.OnDrawNode(e); } ps.: It looks like the OnPaint event isnt fired on a TreeView. Couldnt find why is this on MSDN. Thanks! Diego Valdevino

I need to do some owner draw/ custom controls, and i dont have a clue

How can I create some custom controls using only the win32 API??? Is there any tutorial about this subject?? ps: I kinda want to do something that looks like RealOne.

does someone has a pdf or e-book about win32 programming? I need one! paladino_rapaz@bol.com.br

How can I put a array that represents an image on my window. Have I to create a DC or something? Name of functions and explanations would be very nice.

I have just started today with dirctx8 and I want to make a window in full screen mode. The DX SDK says to create a "topmost" window with WS_EX_TOPMOST. I had my window topmost , but not Maximized. How can I do it ? ps: Without window borders!!!
