You can set the form's cursor property into wait cursor at the Form_load event. instead You can improve the Form loading performace by setting form's property DoubleBuffered=true

Thanks for the reply but i want to make my application compatible with
Yahoo, MSN and AOL.
Do these messengers expose any kind of services which can be accessed
and then the messages can be transfered?

Thanks,
Pramod

2.When I enter the text and hit enter, I wanted to do same function as Send
button, instead the cursor is going to next line on hitting enter key.

Please help me , I tried changing all the events/properties but didn't work.

Hi, Aruna.
1. treeview.HideSelection = false.
2. You can a) set form.AcceptButton = btnSend if your form is a dialog or you can b) handle KeyDown event of the textbox:

private void textbox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData == Keys.Enter)
    {
        // Handle Enter here.
    }
}

How to wrapper a MFC Dll , please help!!!

i have a MFC dll from a video capturer SDK which i want to use in C#.

it was defined in MFC function with a class named AVEControl.

i have not the source code of the Dll but only the head file as below.

if i use [DllImport] directly, an runtime exception is shown with the message "can not found the entrypoint in *.dll".

i guess it was because all function is in the class so i can not call it directly.

so i want to know how to wrapper it with VC++.net or otherwise.

<here is="" the="" head="" file="" of="" dll="">

!!!please notice the DEFINE of CLASS!!!

Use PInvoke instead.

If it were a class it would have utilized the ATL helper methods and an entry point would have been found.

If you need any more explanation try checking your column names to make sure that they match up.

Nope

The exception quite clearly states that it can't find the ID column in the DataRowView so that's where you'll have to look.

richtextbox : can I display a normal string as a URL

Hi,
I'm wrinting a windows application in C# and want to build a 'breadcrumbs' section to show the user where they are in the application.

In keeping with the webstyle of breadcrumbs most users are familiar with I want my breadcrumbs to display as hyperlinks.

I tried using a group of linklabels (on for each level) but I have trouble with this when one of the level names is so long that it overwrites part or all of the next label... so I thought I'd use a richtextbox.

I declared a couple of strings to handle the rtf syntax:

<br />
string rtfStart = "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033{\\fonttbl{\\f0\\fnil\\fcharset0 Verdana;}}\r\n\\viewkind4\\uc1\\pard\\f0\\fs18 ";<br />
string rtfEnd = "/\\par\r\n}\r\n";

then added my level names inbetween:

<br />
            string test = rtfStart + root + Separator + deck + rtfEnd;<br />
            richTextBoxBreadCrumbs.Rtf = test;<br />

However this just displays my level names without URL style formatting.

So my question is, can you force a richtextbox to display a string which is not a URL as a URL and if so, what am I doing wrong?

If this can't be done and I have to resort to using a linklabel, is there any way to deduce which part of a link label has been clicked if I just build my breadcrumbs as one long linklabel?

use System.Globalization; namesapce<br />
and check <br />

if(CultureInfo.CurrentCulture.DisplayName=="Latin") //Note Check the exact name of Language it would not be "Latin" in your system<br />
<br />
to get currently istalled cultures name use CultureInfo.InstalledUICulture.DisplayName

I do not think there is a direct way. You can go though the CultureInfo's TextInfo property and get the code page (ANSI, OEM or whatever you like) and try to base it on this. It would probably narrow it down to a few codepages you should "include", but to be honest I am afraid you might as well create a manual list and check the major language name. It should not take toooo long. Smile | :)
