PostMessage Mouseclicks - Click Behind The Scenes On "Pandoras Desktop App"
Mar 25, 2010
Ive looked everywhre for an example they all generally don't work. Im trying to click behind the scenes on "Pandoras Desktop App" Its powered by adobe air (i dont know if that makes much of a difference), i can get the hwnd properly, but after that im lost. ive tried Sendmessaging &H201 but it didnt seem to do anything. Also, for most examples they use notepad with the edit class, how would i get classes on pandoras app? or would i just send the mouseclick directly to the parentHwnd?

I 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 know how to send mouse clicks and keystrokes into an application when it is open and active, but this particular application the task is very repetitive and can be done with a script of sorts. What i want is how do i make a program to be able to send inputs (key clicks) into the application when it is minimized (the application minimized that is). doing this minimized would then allow me to do other more important things whilst the vb program is sending instructions into the other app.[code]...

I have some reports and queries that are going to be stored in 2 databases. One database 'client', will house the client specific queries and reports and the other database, 'all', will contain the application along with default reports and queries with the same names. The issue is that the clients will have their own specific queries/reports that when I install a new database to them it will eliminate their custom reports/queries.
What I want to is to be able to import these objects from 'client' every time the user logs in. This will ensure that I always have the correct information for the client.Here is my current code. (I know it may not be the best method but I am open to improvements.):
Private Function Insert()
Dim Custom
Custom = "some file location"[code]......

I have an Argox Barcode Scanner with a USB port, which inputs data like a keyboard wedge. I've tried scanning barcodes with it with notepad open, and it just dumps the values as plain-text into notepad on a new line every time.
I am creating an application which controls some custom electronics, and displays data on-screen at the same time. This application does not have any user-input on the entire form, except for a button which when clicked, takes the user to a login-form, and then onward to an admin control panel to change the way the program behaves. Everything is going to be set up on a PC which behaves like a kiosk, which means there will be no windows interaction by the user, and he will not be allowed any kind of usage on the machine even if he tries to use his keyboard/mouse all he can, except for reading data presented on-screen as interfaced with our custom electronics, or to use the mouse to press the button which invokes the login screen.
Now in this situation, I need to work in a barcode scanner behind the scenes. What I need to do is a user scans a barcode using the reader, and the scanning of the barcode should trigger some code in the background (which does some checking against a database, and then activates something in our electronics, and so on). After the user scans the barcode using the scanner, there is still supposed to be no user-interaction with the program itself.
how I might accomplish this? I have already thought of using a hidden text-box on the form, but that sounds like a temporary work-around rather than a professional solution. Not to mention if the user were to accidentally click anywhere on-screen with the mouse, or click on the login button, it would take focus away from the hidden text-box, and bringing focus back to it each time programatically is quite a task.

I have a timer in winforms that looks for a specific OK dialog on my server (it clicks OK on a third party application that runs out of memory, then restarts it -- there is no other work around). So, when I remote desktop the server and the remote desktop window is active (the actual remote desktop window is active, not the actual window that has the OK that has to be clicked. I can have a window that has nothing to do with the OK, and it works), the program works as it should. It finds the window of the OK, then clicks the OK button fine. When I am not in remote destop, or when the remote desktop window is not active (or selecte) it finds the window and finds the OK button, but cannot click the OK button.

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?

Due to use postmessage tow times, I want add a delay (50) between tow postmessage(), and my timer interval is 1000.
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
If CheckBox10.CheckState = CheckState.Checked Then
st = Int(Val(TextBox17.Text) * 10)

and I konw Thread.Sleep(50) is not good, but how to use timer stop here.

I have an Vb.net application made by a third party , that I need to control using outside resources from a simulated environment and must not interact with the desktop. To simulate inputs that a user would normally input from a special screen with specific keys around it, I've built a test control library to control it and send the form image to a .bmp. The form cannot be visible and showed in taskbar , the bmp output will be displayed by the simulated environment.Using PostMessage and sendKeys work well as long as I don't but ShowInTaskbar = False for the main form. After many read & testing, I have learned enough to try what seems to be the only thing that would work. I've created a form that I setparent using HWND_MESSAGE parameter, this should create a Message-Only Windows, that are supposed to received postMessage, and subclass it's events.msdn.
I can't seem to get it to work, and I was hoping someone could tell me what I'm doing wrong.I have been testing several different ways found through out the web about .net , and short of going into message thread peek and feed(maybe(may be)my last hope), they all seem to work until I take the forms out of the taskbar.[code]

Although there are already a few resources online that address this rough topic, I still haven't found an answer that works for me.I desire to have full communication between my VB.net process and my C++ process. I would like to be able to send a string to and from the C++ process, but for the time being I need to achieve:
Sending a string to the C++ process, and handling it.This creates a few points that I am uncertain on, but I'll try to keep this as simple as possible...using the following function declaration in VB;[code]....
And finally, I used the IPC example here to send the message. This example sends the message using C#, but the concept was all I needed (not to mention that it's a walk in the park to convert such code to VB). Note that in my VB implementation, I didn't need to terminate the string with a null character.

We have a form that is saved to the system tray and can be viewed in one of two ways.One view is like a rectangle and the other view is more of a square. In either case, there is a MaximumSize set on the form. We would like to use WindowState to toggle between the two by allowing the user to click the Maximize / Restore icons in the title bar.The problem is that when the user clicks the Maximize icon, the form jumps to the upper left corner of the screen. This is logical, since a maximized form should be anchored to the upper left. But in our case, the MaximumSize property prevents it from fully maximizing. The actual size is around 800 by 400. If they then click the Restore icon for the second view, it jumps back down to the original location.

First of all, is it even remotely possible to have PostMessage or SendMessage "press keys" inside of a Fullscreen game? I.e. use the Chat? (Requires the user to activate the chat box, type in the message, then send it, which is all done with the keyboard)
I've tried many different ways using WM_KEYDOWN and WM_CHAR, and nothing worked.
[Code]...
I am trying to get it to activate the user's chat by pressing enter, type in the text, then press enter again. Except, I would like for the game to be minimized and allow this to work. Or, if while the game was running in fullscreen, that I was able to use SendMessage or PostMessage to type text into a Command Prompt Window.

I'm trying to send a key stroke to one application, through PostMessage. I am using too Spy++ to try to understand how to send the message, as I do not fully understand its inner workings. In this picture, the first item(selected item) was made with an actual key stroke made by myself. The one with a red elipse around it(below) was made with the following code:
[Code]...
I guess it must have something to do with the last PostMessage() parameter, but I can't figure out how it really works. I can see in the original key stroke the ScanCode = 48, and in mine its 0, and also fExtended is 1 and in mine is 0. How can I make it look the same? edit: Here is the msdn link. [URL].aspx I cannot understand the last parameter's working, if anyone does..

Some of u already know I'm making a 'virtual desktop'- thing.Only one problem. When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.

My application watches two buttons:
1. F11 => my application minimizes and hides another window (windowHandle is its handle), then sends there WM_RBUTTONDOWN (right mouse button click&hold).
2. F12 => my application unhides and restores that window, then sends WM_RBUTTONUP (right mouse button release).
The problem is when I press F11, and then click somewhere (so windowHandle loses focus), the right mouse button releases automatically, but I want it could be released only after I press F12. Here is part of my
Public Sub Tick()
Dim windowHandle As IntPtr = FindWindow(vbNullString, "App")
If GetAsyncKeyState(Keys.F11) Then
[CODE]...
So, is there any way how to not release right mouse button?

I'm working on one of my applications and I'm trying to find a way to use the "Go To Desktop" function that goes directly to the desktop without minimizing any window (This can be achieved by clicking on the Win + D buttons or on the desktop icon in the quick launch toolbar), but how can I activate it using vb? I thought about sending keys but I guess there is more offical ways to do it.
