Click Within A Window Using SendMessage Or PostMessage
Dec 23, 2008
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 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 am trying to write a small plugin for eventghost for one of my software (audio player). EventGhost can send SendMessage or PostMessage messages to control other apps. How can I receive such messages in a VB.NET app?
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?
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 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]
how to properly use the "SendMessage" and "PostMessage" API's. I'm trying to make a simple program that will draw a picture, in the background, in Microsoft Paint.how to "Move the Mouse" and "Hold/Click the Mouse" in the application without having to actually "Do it"
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?
Example I would want my program. To press a button on a window. Like notepad.exe I already know how to get the window handel and call gettext or send. To the edit textbox. But how would a preform a click event? I think its called child class? Say I wanted to click the fille button. How would I start ? I know how to get the name threw spy++ but am not sure how to sendmessage to the button.
I am trying to SendMessage to an app called 'Signal threads' - a test app which sends out a message called TV1_Threads, and listens for a reply. I have shown the values of each variable in the commented areas.
I just bought a nice G15 Gaming Keyboard. It has a nice LCD screen with media keys (Play, Stop, Next, Previous etc,).Anyway, I managed to intercept the original functions to WMP of it (By Global Hotkeying them).Now, I have to send mouse clicks to my own Music Player (Playa!TraX, it isn't my creation) on a specific coord.This is the code i have, it finds the window, and says it clicks, but nothing happens, what am I doing wrong?
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal Hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
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 want to click the button using the "SendMessage" API. On the picture, there all of informations about button. show me an example on how could I click that button? Whole thing with "FindWindowEx" confuses me.
How exactly would I use PostMessage and PeekMessage? I'm trying to make a Client/Server type of program. The server program will send a message to the Client and the client will do a set of commands when it gets that message.
VB express 2008 .net 3.5 or .net 4.0 VB express 2010?I have written application to convert RTF to HTML. The main Purpose of the application is to copy VS code to the clipboard and covert it then put it back into the clipboard as a HTML Document so that it can be pasted into a HTML document such as Windows Live Mail. I found that code copied and pasted is spaced out in in the wrong positions.
The applications works perfect with no bugs so far. I then asked Myself how to go about doing the copy with the least amount of operator interaction. So I added an Icon to the Icon Tray with a right click menu to use to convert once the Rich Text Format was copied to the clipboard. This works fine except you have Five steps, Select the text, Copy to clipboard, Right Click the icon, Select the Converter and Paste. The normal is three steps.
To this the best solution is to add a context menu item to the active form such as the RTF editor or window. So that when you select the Rich Text to copy and right click on the form to bring up that menu then to Just Select the menu Item such as "Copy RT and Convert" I searched and found about 544000 Items and tried to restrict down to no avail. I read until I finally gave up. I did not find any code examples of this. Almost every thing I found related to the web or some other explicit document like Excel and not to the Various windows that could be active with RT in it.
how do you add a context menu item to the context menu of an active rich text format window such as WordPad or VB?I have test in my application that tests to see if it is a RTF in the clipboard so if it is not the converter does nothing.

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)
[code]....
and I konw Thread.Sleep(50) is not good, but how to use timer stop here.
I've done some research and still cannot find a working solution. I am basically setting the foreground window with AppActivate to Google Chrome. This works fine. Then I set the cursor location to a specific point. Fortunately, the last step of this process is to send a left mouse click but the code below occurs with an exception and does not execute:
Public Declare Auto Function SetCursorPos Lib "User32.dll" (ByVal X As Integer, ByVal Y As Integer) As Long Public Declare Auto Function GetCursorPos Lib "User32.dll" (ByRef lpPoint As Point) As Long
I was wondering, how you click a button, on a pop up window?
For example, in my webbrowser1 control, i browse to a page, click a button, in turn it pops up a smaller window, that has a button i want to click on. How do i target that pop up window?
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.
How can I detect the click event of the close (X) button at the top right corner of the control box of a form/window? Please note, I don't want to know about CloseReason, FormClosing, FormClosed or stuffs like these, unless they are inevitable. I exactly want to detect if the user clicked the X button of the form.
