Text of one textbox to another program...

[decrypt]

Hi, me and my brother were wondering if it was possible to put text into another program. I'll use netmeeting as an example: The person types in an ip on your form. They click a button and it transmits data to netmeeting and puts it into the box were the ip is supposed to go. Is this possible? (in vb.net)

[NK2000]

yes it is possible but you need the handle for this object

i used such a thing at a tool for a game named Ultima Online

you can find handles with Spy++ but i dont know if they change at each startup

but normally the window name doesnt change so you just have to know how many times you have to send the TAB key (switch to next control in the form) and then just send the string you want to enter

 

UPDATE:

But you definitly have to use the Win32 lib

 

 

good luck :)

 

 

The code is from my first days in windows coding so maybe you find performance improvements..but worked very well at those times :)

Code used at my tool:

 

using System;

using System.Runtime.InteropServices;

 

namespace UO_Build_World_Builder

{

/// <summary>

/// Zusammendfassende Beschreibung für UO.

/// </summary>

public class UO

{

[DllImport("user32.dll",EntryPoint="FindWindow")]

public static extern int FindWindow(string _ClassName, string _WindowName);

[DllImport("user32.dll",EntryPoint="SendMessage")]

public static extern int SendMessage(int _WindowHandler, int _WM_USER, int _data, int _id);

[DllImport("User32.dll")]

public static extern bool SetForegroundWindow(int hWnd);

 

public static int Handle = 0;

 

public static void GetClientHandle()

{

if (UO.FindWindow("Ultima Online",null) > 0)

UO.Handle = UO.FindWindow("Ultima Online",null);

else if (UO.FindWindow("Ultima Online Third Dawn",null) > 0)

UO.Handle = UO.FindWindow("Ultima Online Third Dawn",null);

else

UO.Handle = 0;

}

 

public static void SendToUO(string text, bool command)

{

UO.GetClientHandle();

if (UO.Handle > 0)

{

if (command == true)

text = Core.CommandPrefix + text;

for(int i = 0; i < text.Length; i++)

{

UO.SendMessage(UO.Handle, (int) Message.KeyDown, 69, 1);

UO.SendMessage(UO.Handle, (int) Message.Char, text, 1);

UO.SendMessage(UO.Handle, (int) Message.KeyUp, 69, 1);

}

UO.SendMessage(UO.Handle, (int) Message.Char, (int) Key.Return, 0);

UO.SetForegroundWindow(UO.Handle);

}

else

{

System.Windows.Forms.MessageBox.Show("Ultima Online is NOT started","Error",System.Windows.Forms.MessageBoxButtons.OK,System.Windows.Forms.MessageBoxIcon.Error);

}

 

/*

Core.Parent.Show();

what is spy++?

[NK2000]

one way to open is to start Visual Studio and at the menu Extras you find spy++

 

with spy++ you can get window handles for example and more

important is that you get the windowclass if not then you have to find your window by the titlename of the window

[decrypt]

i can't find the windows extras in v.s... all i can find is external tools in the menu, and that doesn't even contain it...

[samsmithnz]

Try using the Start menu, find Visual Studio .NET, and theres a folder called Visual Studio .NET Tools

[mutant]

Decrypt, if you have VB.NET Standard, it does not come with Spy++.

[decrypt]

yeah that would explain a bit...

[NK2000]

oh i am sorry didnt know that, but if you need any spy++ output data just tell me what to "spy out" and i will provide you with txt and jpg :)

[decrypt]

I found something called "Control Inspector" @ Control Inspector Do you think it's like spy++?

 

Edit: ah ha i found something even better called WinSpy here

 

Edit2: I see how your code works. Do you think that this is possible in vb.net? i think your code is in c#?

it doesnt matter what in c# work it matter what in .net work and since we use same framework.... :D

 

good luck, just look at DllImportAttribute i think it is the same keyword at vb.net it should be also in InteropServices namespace

[NK2000]

this winspy tool looks in some aspects better than spy++

[decrypt]

i found a c# complier... can you tell me how the code works? (comment it perhaps...)

[decrypt]

What part of the code tells the location of the textbox? Also what part defines the message? Edited February 29, 2004 by decrypt
