I'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 have been trying to use vb2008 to automatically update CustomDocumentProperties fields that I have set up within a pro-forma document. I can load the Word application and word document without problems.I want to update the CustomDocumentProperties fields with data read from a dB. To do this I am assuming that I need to iterate through the CustomDocumentProperties fields within the word document and when one is "found" that matches the data I wish to merge then assign the dB value to the field.The problem is that I am getting an exception error when I try to reference the document customdocumentproperties
"Error : Unable to cast the COM object of type 'System._ComObject' to interface type 'Microsoft.Office.Interop.Word.CustomProperties'. ...... "
my code looks like;
Dim WordApp As Word._Application
Dim odoc As Word._Document
Dim BContinue As Boolean = True

View 8 RepliesI'm trying to send some words to an application I'm running (exe file, no webpage). To do this I run my vb program and minimize it, so that the application I want to send the words to have focus.Now I've tried sendkeys, but it seems sendkeys only sends my first word and does nothing with the other words. The code below is called 4 times by the main form
If i > 3 Then i = 0
i = i + 1
If i = 1 Then verhaal ="some text 1"[code]....
but this throws in a overflowexception was unhandled error at the apiSendMessage(hWnd, WM_SETTEXT, 0, "Hello") line.I've tried several things but I can't figure it out how to send multiple words to the application without problems .
I am using SendMessageTimeout to send messages (IPC) to talk between applications ... works fine in vb... but i am trying to build a vb.net implementation to talk between existing vb6 apps and .net ones...
So far i can successfully send data from vb.net to vb6 using:
vb
Dim b = System.Text.UnicodeEncoding.ASCII.GetBytes(Command)
Dim Data As New COPYDATASTRUCT
Data.dwData = New IntPtr
Data.cdData = UBound(b) + 1

Type.GetTypeFromProgID("Word.Application") returns nothing
View 2 RepliesI would like to get the x, y position from the Params when the WM_LBUTTONDOWN is sent in vb.net.I got this to make the param but how do I get the position from it.
IntPtr lParam = (IntPtr)((y << 16) | x);
My function:
Protected Overrides Sub WndProc(ByRef m As Message)
Select Case m.Msg
Case WM_LBUTTONDOWN

Update: I just tried this and it works perfectly.
Dim pos As New System.Drawing.Point(CInt(m.LParam))
Private Const WM_KEYDOWN = &H100
Private Const WM_KEYUP = &H101
Private Const VK_BACKSPACE = &H8
[code].....
I have this code:
Private Const MOUSEEVENTF_LEFTDOWN = &H2
Private Const MOUSEEVENTF_LEFTUP = &H4
Dim WindowHandle As Long = FindWindow(vbNullString, "Ultima Online")
SendMessage(WindowHandle, MOUSEEVENTF_LEFTDOWN, 0, 0)
SendMessage(WindowHandle, MOUSEEVENTF_LEFTUP, 0, 0)
I know it is getting the windowhandle fine, because I made a conditional statment that pops up a messagebox if windowhandle = 0 The problem is that it is not sending the mouse click to the window.

Damned. Is there a managed code somewhere in vb.net where mortals can simulate key presses?
Is there an e-book or book somewhere about it?

View 2 RepliesI use keybd_event and mouse_event to simulate keypresses. I want taht to still work when the user is switch (Xp supports several users as we know).
Well, it doesn't.
I've heard sendmessage is more reliable,.
I manage to simulate click easily.
SimulateClick2 = SendMessage(hwnd, BM_CLICK, 0, 0)
Now, how to do so to simulate keypresses?
Can anyone give me a SendMessage/PostMessage Example? I want to make SendMessage/PostMessage work like SendKeys, except instead of sending keys to the app in focus, it will send keys to a certain app. I've looked at a lot of examples that use notepad, but they all need to use "find" the "EDIT" thing. I dont want that. Is there any other way?

I am Automating IBM iSeries Emulators using VB.net, created GUI that embeds the external iSeries Emulator Window in a WindowsForm Panel using the "SetParent" API .. To communicate with the iSeries Window I use the SendMessage API to send Key's to the Screen.

I developed a little app which uses SendMessage function to turn off monitor. My friend asked me whether using the app regularly will harm his monitor. He had some issues with his mother board when he used a similar app. Is there any harm (for hardware) in using the function to do things like these?
View 1 RepliesI am launching an external that brings up a window that is split into two frames. I am able to get the handle of the frame and what I want to do is click inside the frame in a certain area.
For example, if I open "System Information" by launching msinfo32.exe, how would I click on Internet Settings in the left window pane? I don't need the exact coordinates, just an explanation of how it can be done using SendMessage or PostMessage.
I've tried things like:
PostMessage(sideWnd, WM_LBUTTONDOWN, 200, 1200)
PostMessage(sideWnd, WM_LBUTTONUP, 200, 1200)
I wasn't sure if the end two numbers would be coordinates, but if they are, I've tried different numbers and can't seem to get it to click anything other than the first item in the list of the left window frame.
I need an API for sendmessage and sendmessagetimeout for my VB .net application. I have searched quite a bit, and everything I find doesn't seem to work: either the message just doesnt seem to be sent, or the message appears to be sent with the msg parameter always 0, and the wparam setting as what I enter for the msg setting. Pinvoke's also always seems to throw an AccessViolationException for I have no idea what reason. I tried playing around with maybe just where I put the variable, but unsurprisingly, there is not a simple logical switch of the variables.I have tried pinvoke's:
