I can't understand why it's not clear for you. I just want to modify that code to work on Windows 7 too. If you know the answer please let me know. If you don't know the answer just ignore it.

"doesn't work" does not convey any information, that is the problem with your post. What is happening? the program refuses to launch? it throws an exception? it exits without any message? the computer explodes? or what?

"doctor, it hurts" cannot be turned into an effective diagnosis.

Identify the part that's failing and try and write a replacement for it.

I have developed one GUI in vb.net but now I want to use C as backend code along with MySql as database.
Is it possible to create such a application.

I have been using C and MySql under Fedora and I have my GUI ready in vb.net. Can you tell me how can I communicate these thing together?

For ex. I have add button on front end, when I click add button, and instead of defining functionality in vb.net I want to send input to C function and then C function will execute and return output.

Using a variety of techniques. What's the VB.NET GUI running on, is it a Windows system, or is it running on the same Fedora-machine?

Easiest way to have them communicate would be over web-services.

You can also export your C classes in such a way that VB.net can use them like you would API calls. I did this on a shell I developed so that I could get the sytem tray icons. Search google for "Use C++ DLL in VB.net". Another option is to use WndProc messages between the two applications. That's the way I would go personally. The concept you'll want to research is "inter-process communication".

Hello All,

I was wondering if there is a snippet that allows your program to follow out programming when it is terminated through task manager or similar tool. For example (Not valid code):

Private Sub OnTerminate() Handles Form1

Wondering if there is such a thing you could implement into your application Smile | :)

Simple Thanks and Regards,

There's no such thing.

Task Manager tries to shut down your app nicely, by sending a message to it exactly like the user closed the main window.

If the app doesn't respond in time, the app is stopped completely and all memory for it freed. Your code never gets a chance to respond to anything as it's not running anymore.

The original app could simply be halted by Windows, being unloaded from memory without any warning. A simple solution would be a watchdog-application; write an app that starts your original app, and have it check from time to time whether it's still alive.

Hello, I would like to as you if there is a way I can perform a reverse IP domain lookup (get all the domains of the websites that are hosted on that server) using vb.net

Something like this: http://www.yougetsignal.com/tools/web-sites-on-web-server/[^]

It would be awesome if you could provide me with the source code.

Regards,

You should start with the hardware you're going to be controlling and it's specifications and documentation. You're also going to have to learn G-Code, what each instruction means, how to parse it and translate that to motion of the tool head, ...

Judging by your question history, this project is WAY over your head right now.

Thanks for the reply , i did study G-Codes, The only thing making me confused is weather to do it in vb or C.

Here is a quick / rough way that I would count the characters in a string

Dim s As Char() = TextBox1.Text.ToCharArray
Dim p As New Dictionary(Of Char, integer)

For Each chars As Char In s
    'ignore the spaces
    If Not chars = " " Then
        'count the occurances of the character
        Dim i As Integer = s.Count(Function(r) r = chars)

        'if the letter is not in the dictonary
        If Not p.ContainsKey(chars) = True Then
            p.Add(chars, i)
        End If
    End If
Next
