I am developing an application that reads an MDI applications child window and grabs the information from a control such as a textbox or listbox. I have tried to use Findwindow in order to accomplish this. I have gotten all the way to the control, but once I get there it returns blank. Can anyone point me in the right direction to accomplish this.I am able to read the window title and get the control title but when I send a message to the window it returns 0. Now I am just experimenting so I have no concrete code, but here is a snippet. [code]
View 1 RepliesI'm trying to teach myself to use SendMessage to manipulate other windows and have been reading as much as possible on the net to understand how to do this. I've come upon a problem though that I have been unable to find an answer for on the net. Currently I'm attempting to read text from another window. I am under the impression that I use FindWindowEx to dig into a target window's handle and find the controls in the form, although I still haven't been able to do it successfully. I read somewhere that I use Spy++ to find the names of the classes I am searching for with FindWindowEx, and that once I have the handle of the specific control containing the text I use SendMessage to send it a WM_GETTEXT message. The problem I'm having is that for the lParam MSDN says that SendMessage needs a "Buffer", and I'm not sure how to use one of those. I tried using the type Buffer, but that didn't seem to work. Is buffer a euphamism for a certain variable type? I tried using IntPtr as well but the returned IntPtr was always IntPtr.Zero...
So basically my questions are:
1. How exactly can I use FindWindowEx to locate a control's handle? I'm having trouble getting it to work, but I'm probably just not understanding how it functions.
2. What is the variable type for the "buffer" required in lParam of the WM_GETTEXT SendMessage?
I am trying to figure out how to make my program copy text from another applications screen. For example if I wanted to copy the text from an AIM chatbox I imagine it would be simple but cannot find anything on this, interacting with other applications is a next concept for me
View 1 RepliesI'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.

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 have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

View 13 RepliesI am trying to find all text from a slightly older application. The thing is, the old scripit from windows NT finds the text I need no problem, but I cant seem to get it myself.
I find the main window, and cycle through its children, but must be looking at something wrong. I am missing 2 things: The title of the app has the name, and then some status information, the status information does not show up on the window title info. The text in the application itself does not reveal itself to me either
Here is a code snippet of how I try to get the info out:
Private Sub gettext(ByVal hd As IntPtr)
Dim Hwnd As IntPtr = hd
'Alloc memory for the buffer that recieves the text

View 5 RepliesI searched the forums to look for an answer and I found several good exemples, but unfortunately, none worked for me..I want to make a little program to read an Edit field on another window. I understand the basic. I need to get the handle of the main window (using FindWindow) and then find the handle of the Edit field (Using FindWindowEx). So far, so good... I think I managed to get those two correctly doing:
Declare Auto Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal strClassName As String, ByVal strWindowText As String) As Long Declare Auto Function FindWindowEx Lib "user32" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Dim hWindow, hText As Long
hWindow = FindWindow("", "Text")
hText = FindWindowEx(hWindow, 0, "Edit", vbNullString)
(Yes the window title is Text :P). Ok now when I do a MsgBox(hText) it does show a long number (not 0) so I believe it found the Edit field (but I'm not so sure on how to verify if it's the right number... tried Spy++ with no luck).Now, this is where I'm stuck. I know I have to use SendMessage() with WM_GETTEXTLENGTH and WM_GETTEXT which I tried maybe in 100 different ways and none of them worked. I either got an OverflowException or my String would stay empty.

Is what I tried after researching how to get clean text on an aero window, but it is still not nice looking.
I am trying to grab what appears to be text of a label from a different process so I can show what it says in my own program using pre-recorded audio files, basically trying to read the programs text to the user, one of the things im missing is reading a label, it appears to be easy to read the Edit control/textbox you can type into & other things but I cant seem to find out reading this label.
