Read Text From An External Applications Textbox?
Sep 27, 2011
I am trying to extend some features of a external programm that is not able to use plugins or something. So I have to write my own app that reads the text from a textbox from this external application and trigger some own actions.
By using the FindWindow API in user32.dll I allready catched up the handle for the external application. But now I am kind of stuck. By using Spy++ from the Visual Studio Tools I got the information that the class name from the control I would like to read from is "WindowsForms10.EDIT.app.0.218f99c", but there are several of them. Additionally every time the external app starts it creates a new control id for the textbox I want to read.

I like to read text from another application's buttons, labels and textboxes with the help of "SendMessage". I've tried so many different code examples, but nothing worked. Maybe somebody of you has a small VB.Net-Example on your harddrive and explain it a bit to me.

removing the title bar of external applications.
I want the affected application no to have the title bar.. you know, with the app name, the mini, grow, and X button.
The reason I want to do this, is because my program docks external programs into a picturebox, but when I use this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Handle As Integer
[Code].....

I am using VS 2010 to create a Mac OSX like dock application.Everything has worked great apart from one of the key features of the dock! So what I want is:When the user clicks the minimize but on any (including external application) it minimize to the dock I have created rather than the windows Task-bar.

I would like to know how to write a "Console application" in dll form for a patch installer so that I could call it from the installers and find out the installation of a program.I have created a VB.NET class project and checked the COM Interoperation or sort of on project's property, build section.Now the main thing is on receiving parameters and returning the value. (I try to do this DLL as "all-in-one" DLL because this application is part of a bigger suite family, which means there are few others applications that requires the similar approach, and I want to avoid to re-write a dll for each application, and their respective versions.)

Whats up all I've recently been working with the MDI options in vb.net but I have a question. Is there away to open external applications inside of the MDI application. What I mean is Taking command prompt for example and opening it withing my MDI app. It only shows the file in my app and not on the taskbar. Can I do it or no?

I am developing an application which launch an external windows app, ei called APL.exe Also, this APL.exe launch two console utils, ie. named CON1.exe and CON2.exe I would like to know if is there any way, after APL.exe has died, of killing CON1.exe and CON2.exe, because there is a small possibility that they will not died completly after APL.exe has exited.Also there is another requirement. My final app version could be executed twice in the same machine, so there could be two instances of CON1.exe and CON2.exe, and because this I need a way to kill them not by process name, but knowing which of them has been launched by my current application instance.

Trying to emulate a typing application that when typing data in a WPF form, the info gets transferred to another application, such as notepad, word, etc. My first attempt involved using the .Sendkeys method but it doesn't seem to be repeatable 100% of the time. I initially had a button that when pressed would transfer data from a WPF app field to an open notepad app. Again, if I pressed it several times in a row, it would be hit or miss. It's like it hangs up and then after enough time, I try again and it works. I really need it to be 100%. Is there a fix for this method or should I take on a different approach? It would be ideal if I could go from notepad, word, etc. back to the WPF form as well, but I thought I would get one way working first.

I have a situation where I have a vb.net program that uses two connection strings. This program will be used on multiple web servers on multiple domains and the only difference for any of them is the two connection strings.What would be the best solution to read in these connection strings from a file separate from my actual .vb code?
Ideally I want to be able to drop the .vb and the connection string file into its own folder on any number of asp.net websites and not update anything else (for example add any connections to the web.config or anything) than the external file containing the connection strings, I assume something like xml would suffice?

I'm having difficulty figuring out how to run different programs with my VB program. Using Excel and other MS office programs is easy enough since I just add in the relevant COMs, but I can't for the life of me find out how to run other programs. I promise I spent many hours searching before bothering you kind folks here! I'd think this is a common issue so maybe I haven't been searching for the right thing.how to write code that will control and read data from applications.I know you can do "Process.Start" to open any application, and it looks like there are ways to determine the controls available on an open application, but I can't figure out how to do it. Is this possible? Or do I have to import a .dll file for every program I want to control? Or are both possible?

I am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.

I am using Visual Basic 2008 Express Edition. Some of the programs I am writing make extensive use of External files (saved games, data, item lists, etc.) I could use an easy way to get these files to ride allong during deployment (cd mostly). adding them to the resources works for some static pictures, but custom structures into lists of info to read and write from are beond that features abilities, same with the settings feature. I have found in other help referance to "MageUI.exe" so is downloading a .net SDK my solution or is there a better trick I can use?

Essentially what I would like to do is press a button, this then triggers a code to focus on a certain program, focus on a certain textbox and input the text from the clipboard not via pasting.
Now I have been able to achieve all of the above fairly easily except for one crucial component, focusing on the desired component. This program is essentially to automate some data entering for users via hotkeys, therefore I can't simply simulate tabs as it will not always be in the same position. So now comes the question, how do I focus on specific textboxes/controls in other programs?
I've been able to find huge walls of code with no explanation beyond "this is a concept". However no documentation or relevant examples.

I'm trying to retrieve the text from an external text control. I'm able to do this successfully in vb6, but now that I'm trying to make a go of .net I'm having trouble writing this particular piece of code in .net without errors.
My code is thus:
Dim TheText As String, TxtLen As Long
TxtLen = SendMessageLong(txtcontrolclass, WM_GETTEXTLENGTH, 0&, 0&)
TheText = String(TxtLen + 1, " ")
[Code]....
I also noticed that my use of String( and Left( in the above code are also underlined and telling me that they cant be used as written.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

how to redirect outputs from console to a window form text box,but the console application I'm using is always running real time, thus my .net application hangs until I close the program that is read real time.The code displays the application to a 2nd form with a textbox multi line. Until I close that my entire program hangs and the console application monitored runs.
How do I code it to:
1. Run real time without hanging the entire program.
2. the console app must run at all times. (figured how to hide/ and no window created for it)
Sub Console()
Form2.Show()
Dim myCon As New Process
myCon.StartInfo.UseShellExecute = False

I've got a problem to make two applications to send text-data between themselves.
The message is transmited without any problems, the awnser is received too. But, there is a lot of a "New line" char in the end of the string send/received on each side. I guess it's because of i'm readeing the full buffer; i've tried to remove all Chr(10) and Chr(13); I also tried to trim the string, but it didn't worked.
Here the code I use :
Client Side :
Dim cl As New TcpClient
cl.Connect("127.0.0.1", 2000)
Dim str As NetworkStream = cl.GetStream
[Code]....
UTF8 works on 4 bytes, and when I read the stream and I put it into a buffer, if there is no char, the 4 bytes stay on a 0 value.
