Re: Custom Treeview with Overridden OnPaint & WndProc

8-Jul-09 10:55

Not entirely sure that is the direction I want to be taking. This just appears to erase my entire custom treeview with no call to OnPaint.

I'm trying to keep the way the rest of the nodes aside from a selected node to look the norm. I need to keep the selected node the focus color as buttons are pressed even though this goes against standard convention. The thought was to make a custom treeview with custom onpaint to repaint this one node with a rectangle using onpaint and then putting back the original text on top.

Then I read this: http://www.codeproject.com/Messages/685886/Re-Custom-Tree-View-Painting.aspx and came to the overriding WndProc, but was unsure on how to procede with the call to OnPaint.

I need to keep the selected node the focus color

If that's all your after then set the: "HideSelection" property to false. This setting allows you to retain visibility of the selected node once the treeview has lost focus.

If you still want your own paint, just manualy set the node's properties:

tv.SelectedNode.BackColor = SystemColors.Highlight;
...

The hurrier I go, the behinder I get.

HideSelection will not work for this instance and changing the BackColor will not address the issue I have. My button moves the selected node up and down. Since it is no longer the focus, it turns from medium blue to light gray. I did however figure out how to override WndProc:

protected override void WndProc(ref Message m)
{
base.WndProc(ref m);

switch (m.Msg)
{
case (15):
{
PaintEventArgs pae = new PaintEventArgs(
Graphics.FromHwnd((m.HWnd)),
new Rectangle(0, 0, this.Width, this.Height));

OnPaint(pae);
break;
}
default:
{
break;
}
}
}

Thanks for trying!

Well, there are a couple of options.
You can use Office Interops to read the excel file and then create the second with the data of your interest.
Another way can be to read the excel sheet using the ADO connection into a dataset and you can write the selected rows as a xml file (using Dataset.writeTo method). Excel can easily read the xml file. Rose | [Rose]

What have you tried already? Have you researched how to do read and write from excel files? Many people don't like doing work for free, and 'sample' code exists on the internet everywhere, if you have tried using google that is.

The Cryptography namespace is where you need to go. Thing is, do you want to encrypt the XML ( which will mean it's not XML anymore ), or some of the data IN the XML ?

Event log query... very odd!

Hi All,

i have a code (below), it take 2 variables, the first being the server name and the second being the eventID to look for in the Directory Service eventlog.
it seems to work fine for all eventID's except the one im looking for - 1394, where it always shows nothing!!

any ideas?

EventLog el = new EventLog("Directory Service", args[0].ToString());
foreach(EventLogEntry i in el.Entries)
{
if(Convert.ToInt32(i.EventID) == Convert.ToInt32(args[1]))
{
Console.WriteLine(i.EventID.ToString() + " - " + i.TimeWritten.ToShortDateString());
}
}

First, yoiu don't use picturebox's this way. All you do is use a button, set it's Image property to the dimmed image. Handle the MouseEnter and MouseLeave events of the button. In those handlers, just change the Image property to point to either the dimmed or brighted image as appropriate. No pictureboxs involved at all.

BTW - the more controls you have on a form, the slow it renders. The only way to speed things up is to reduce the number of controls on the form.

Custom TreeView

I'm trying to create a custom treeview that will draw a blue rectangle over a selected node and then redraw the text over it. Is there any command that can help me find the (x,y) coordinates of the node? The node can be selected by either mouse, keyboard, or a button. Any suggestions?

How about using the Bounds property of the node? that good enough for what you want?
