How about this

AppDomain.CurrentDomain.BaseDirectory

I think you deploy the project use the clickonce,am I right?

Application.UserAppDataPath

It'll return like follow: "C:\\Documents and Settings\\mis-hongwenshi\\Application Data\\ccc\\WindowsApplication11\\1.0.0.0"

    protected override void OnAfterInstall(System.Collections.IDictionary savedState)
    {
        string t\_path = this.Context.Parameters\["assemblypath"\].ToString();
        Configuration \_usrConfigLoc = System.Configuration.ConfigurationManager.OpenExeConfiguration(Path.Combine(t\_path,"user.config"));
        //...
        base.OnAfterInstall(savedState);
    }

The problem is, intermittently i get the error: Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80080005. It throw up when I use:

Excel.Application app = new Microsoft.Office.Interop.Excel.Application();

and it happens randomly. What could be the reason? Dose anyone have any experience with this,thanks in advance for ur assistance.

I have an other Thread t,and I can get the checkbox value from UI thread in Thread t. see follow source code.

    private void Form2\_Load(object sender, EventArgs e)
    {
        Thread t = new Thread(new ThreadStart(deal));
        t.Name = "deal";
        t.IsBackground = true;
        t.Start();
    }

    void deal()
    {
        while (true)
        {
            System.Diagnostics.Debug.WriteLine(checkBox1.Checked);
            Thread.Sleep(1000);
        }
    }

Thks again! Greate,Use the hook can figure out my "Question". [See here](http://support.microsoft.com/default.aspx?scid=kb;en-us;318804)[[^](http://support.microsoft.com/default.aspx?scid=kb;en-us;318804 "New Window")]

It seems it wasn't catch by PreFilterMessage. Is there some way to catch WM_CREATE for all forms in my application without override those WndProc in each winform?

Thanks, I remove the override method of WndProc from form1,but it didn't work fine. PS:We can capture all msgs except the WM_CREATE in PreFilterMessage method.

Also use this[^] overload of Application.Run.

I have changed Form1 f = new Form1(); f.Show(); Application.Run(); to Application.Run(new Form1()); May be I didn't clear what you mean.

I can get the WM_CREATE msg in WndProc when I click button1,but it didn't fired at the PreFilterMessage. Follow is the source code.Thanks!

        Form1 f = new Form1();

change the p.Width = 1.5f; to p.Width = 10f; you can see the left and top line were drawed.

I think the cause is the graphics,which belong to panel1(the parent of groupbox1),we drawed the rectangle on the panel1 but it just under the groupbox1.So the rectangle we drawed were cover by the groupbox1.

Thanks again!

The right and bottom line are probably not appearing because they're outside the clip rectangle

I use the Inflate(-2, -2) to make sure the Rectangle was inside the clip rectangle,but they're still not appearing. follow is the test code.

Ok,I get it,follow

ctrlP = ctrl.Parent;

Rectangle r = ctrl.Bounds;

Rectangle rP = new Rectangle(0, 0, ctrlP.Width, ctrlP.Height);
r.Intersect(rP);

but I have new issue,I want to draw the border of the "display bound"

Graphics g = ctrlP.CreateGraphics();

Pen p = new Pen(Color.Red);
p.Width = 1.5f;

g.DrawRectangle(p, r);
g.Dispose();

It draw the top and the left line fine,but the right and the bottom line were clear,because OnPaint event of ctrl? and this method was fired in Form_Paint(object sender, PaintEventArgs e).

So if I want to make it, I need to consider all those special controls, It's not a easy thing,right? Did anybody have idea about how display all controls in winfroms at runtime like vs2005 doc outline tool in designtime?

Thanks! I have two container controls like follow "a" and "b" ┌────┐ ｜            ｜ ｜   a      ｜ ｜            ｜ └────┘ ┌───────┐ ｜                     ｜ ｜   b               ｜ ｜                     ｜ └───────┘ b is bigger than a And I drag b into a,so b only display the visible area and I want to get that,not b.bounds ┌────┐ ｜ a┌──┤ ｜   ｜      ｜ ｜   ｜ b   ｜ └─┴──┘ how can I get it?

I can give the rectangle of a control by bounds.but I don't know how get the visble rectangle when a control not display whole.

Rectangle r = ctrl.Bounds;

ctrl.DisplayRectangle;:confused:

Thanks for your reply I had already use the recursive method-->"addNode(Control ctrl, TreeNode tn)"

...f is a Form                   Control t_ctrl;                   for (int i = 0; i < f.Controls.Count; i++)                   {                         t_ctrl = f.Controls[i];                         TreeNode t_tn = new TreeNode(string.IsNullOrEmpty(t_ctrl.Text) ? t_ctrl.Name : t_ctrl.Text);                         t_tn.Tag = t_ctrl;                         self.treeView1.Nodes.Add(t_tn);                         addNode(t_ctrl, t_tn);                   } ...             private static void addNode(Control ctrl, TreeNode tn)             {                   Control t_ctrl;                   for (int i = 0; i < ctrl.Controls.Count; i++)                   {                         t_ctrl = ctrl.Controls[i];                         TreeNode t_tn = new TreeNode(string.IsNullOrEmpty(t_ctrl.Text) ? t_ctrl.Name : t_ctrl.Text);                         t_tn.Tag = t_ctrl;                         tn.Nodes.Add(t_tn);                         if (t_ctrl.Controls.Count != 0)                         { addNode(t_ctrl, t_tn); }                   }        &nb
