Howdy Folks!

Does anybody know of a way I can identify the current x,y location of the cursor in a Rich Text Box?

(Just for clarity - I'm talking about the text insertion cursor, not the mouse pointer...)

Thanks in advance!

Mojo.

you could do this : Smile | :)

VB:

<font color="blue">Private</font> void richTextBox1_MouseMove(<font color="blue">Object</font> sender,System.Windows.Forms.MouseEventArgs e)
        {
            <font color="blue">Try</font>
            {
                <font color="blue">Char</font> c=new <font color="blue">Char</font>();
                System.Drawing.Point p=new System.Drawing.Point();
                p.X=e.X;<font color="#006400">//current x of cursor In rtf box</font>
                p.Y=e.Y;<font color="#006400">//current y.</font>
                c=richTextBox1.GetCharFromPosition(p);
                this.Text=(Convert.ToString(c));<font color="#006400">//retrieve the character at the current cursor position.</font>
            }
            <font color="blue">Catch</font>
            {
                System.Exception f=new System.Exception();<font color="#006400">//just incase you Try When there</font><font color="darkgreen">'s no text in the richtextbox</font>
                MessageBox.Show(f.Message.ToString());
            }
        }

hope that helps a little.

<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
    {    
    <font color="blue">switch</font>(twins)
    {
    <font color="blue">Case</font> ("twins on the way"):
        MessageBox.Show("for mr and mrs dynamic","twins on the way");
    <font color="blue">break</font>;
    }

Thanks everyone for your help!

I eventually managed to do this using:

pt = rtf.PointToScreen(rtf.GetPositionFromCharIndex(rtf.Text.Length))

Yes, compile your MFC application with /clr and use the #using directive for importing the C# DLL. You'll need to use Managed C++ for calling your C# DLL, but it's not a big deal.

Distributing c# app with ActiveX control

I am building a simple test application in c# that uses the Flash player ActiveX control to display some data.

I have two Classes in c#:

FooWindow.cs
Foo.cs

I then embed the Flash player in my app in visual studio.

When I compile everything, it creates the following files:

AxInterop.ShockwaveFlashObjects.dll
Interop.ShockwaveFlashObjects.dll
stdole.dll
Foo.dll
FooWindow.exe

This all works perfectly on my machine, but when I send it to other people to test, they get various errors. I am sending all of the files. Do I have to do anything special to distribute an app which uses an ActiveX control?

Thanks for any input...

When distributing C# apps, you have to make sure A) They have the .NET framework installed (only newest XP has it installed default), and B) Do they have the right version of .NET installed. I have found that 1.0 and 1.1 executables are not interchangeable (which is a bit dissapointing).

Do your testers have Flash installed on their machines?

Yes. Thus far, I have sent it to three people, and it didn't work for any of them.

They all have the same version of the flash player also.

The solution i am going to tell you is what are you going to do with the source code NOT WITH THE DB, which is a bit more difficut.

let's say n is the number of the columns.

System.datatable newtable = new Syste.Data.DataTable();

string colname;

for(int a=0;i

Process.Start() is what you want. I don't understand what invisible mean. with CTRL+ALT+DEL a user can see any application and any process in his system.

by invisible i mean that the process work at the background.....so the user can't SEE it or INTERACT with it...

You can make a service. It would run all the time in the background.

The way I use it is this:
text = text.Replace([string or char to be replaced], [new string or char]);
