VS 2008 Seeking - Getting SendInput To Work
Jul 2, 2009
I asked a similiar question in the VB6 forums with some methods I was trying there, but this is a different method that I'm trying in .Net that I cannot get to work. First what I'm trying to do, I play a game that allows attended macroing, so I'm trying to write a program that I can record and playback macros in. I already have the recording down, and I can playback my macros using older API Keybd_Event and Mouse_event, but not in the game. The game recognize all the mouse events, but does not recognize all the keyboard events. (It is a DirectX based game by the way). For example if I record they keystrokes h e l l o and have notepad in focus and play it back it will type hello in notepad, but in the game they keys are not recognized.

I'm writting a "Console Application" using Visual Basic (VB.net) 2008 Express Edition in a Windows XP SP3 environment, and I'm trying to get SendInput to work.
I have been able to get SendKeys working, and I'll use it if I must, but there are some unpleasant control issues. Plus, it's incompatible with Vista, from everything I've heard.
So, I'm including two attachments. The first is a quick-and-dirty working example of SendMessage (actually SendMessageString) which I've used to half-way convince myself that I know how to use the "user32.dll" API's. (For simplicity, I've stripped out all of the error-testing logic.)
The second bit of code is my unsuccessful attempt to get SendInput to send some test keystrokes to Notepad. (I've heard some people say it can't be done in VB.net. Are they right?) To get a clean compile, I had to comment out 'CopyMemory' because how to get it to work. Is it essential to the code?

i am trying to send keystroke using sendinput but it doesnt seem to be sending. I have sendInput declared in user32 class with the input type
dim key as Keys = Keys.A
Dim inputEvents As New USER32.INPUT

[code]....
am i setting the flags wrong to send a key? not 0 then a 2?

I am trying seek by looping thru a table for the closest match to a search item.
The following code works to a degree. It gets me within say 20 records of the target. I think it works somewhat but it may not be at all.
Code:
Private Sub Find_Item_In_Column(ByVal Search_Field As String)
'Pass a field name to do a string search on
Dim Find_Item As String = InputBox("Enter an Image File Name")
[Code]....
I used the data wizard to establish the connection and I am using VB 2008 Express.
In this case the data field will be a file name and it will be unique. Since the search for string will be a partial of what a file name might be. My expectation is that INCR will match the data row and can then be used to position the TrainImageBindingSource. So far it gets me close, but I am wondering if it is really working at all. I would like to arrive at the closest match (up or down one) found.
Can any one see any glaring errors or point me to an example(s) of similar code snippets?

I'm using the following flavor of threading to create n number of worker threads. These threads all have a bit of latency as they interrogate devices that have strict temporal/physical limits.
[Code]...
I'm looking for a pattern that will let me start the worker threads then wait patiently for completion. Sounds simple ("Just raise an event!") but there seem to be timing landmines. Since the completion EventHandler is single threaded, collisions can occur that destroy the EventHandler data.
Is there a straight forward way for 1 of n threads to report an "I'm done" condition?I've literally got lists of these for c++ but vb.net/CLR is giving me brain freeze.

I've been using SQL OleDB commands to grab data from some excel files and it's working well, but I'm having a really hard time finding a good resource for the actual command strings on the web. I figure I must not be using the proper terminology in my searches. Take this line:
Dim da as New OleDb.OleDbDataAdapter("Select * From [" & sheetName & "]", Conn)
My question this morning was: Can I pass a command that will grab all sheets from the excel document instead of just one in particular?

My curse seems to be SendInput... I have tried many sites and code variations and it never works right... it always returns an error. So can someone just whip together a quick class that has 3 public methods, one for keyboard (that takes a Keys data type) one for mouse, and one for Hardware?

I tried this code with windows7 and xp,with 3 different pcs and both with .net4 and .net3.5 and it doesn't work. Basically I want to press the left mouse button. Searching the net I've found that the only decent solution is to use sendinput function, two times (one for click and one for release) the function always returns 0 with an error code "operation completed", but the the click doesn't happen...

I'm using sendinput to send keystrokes to external applications launched from my main application. However , the only way I have been able to get it to work is by focusing the external application then sending input. I want to know how to use sendinput to send keys to a background process without giving it focus.

I am using SendInput to send some keyboard commands to a dialog box. It is already the active foreground window when I call SendInput. I first send "Return" and then a bunch of other stuff. The dialog box opens with a button selected by default, and when manually selecting Enter, the button is clicked on the dialog progresses to the next screen, but my SendInput call doesn't advance the dialog.

I am replacing an AutoHotkey script with a VB.net application. Part of the script involves sending keystrokes to an active application. VB uses SendInput and does send the keystrokes, but the application doesn't "get" them, but when AutoHotkey sends the same key to the same application, it works. I have verified that VB is indeed sending the keys properly. Does anyone know how to imitate the autohotkey Send function?

Iam wanting touse sendinput in a dos or background type app (can be a regular app thats hidden) that emulates mouse clicks and sends mouse moves to another multimouse application. an project that im working on for my school i work at and i need to send the input to it. The overview of the project is i need to have this code be in a service that runs in the background that when a person does a gesture with my kinect code then it clicks the left mouse or sythesis it with sendinput (need mouse up and down sent for this to work). The end programs that receive input are: a program written in the multipoint sdk and mouse mischief. I though about using the default usb mouse driver as an emulated mouse driver to handle the part about creating a usb mouse device that works
since most newer computers are using usb.

I've been working on an auto talker, and so far, no errors. The only issue im having is to make textbox 3 to work with textbox 1 and textbox 2. I'm using Checkboxes, so You must check the ones you want. Like said, 1+3 and 2+3 doesn't work. It will only spam Textbox 1 OR textbox 2. Textbox 3 will not show up.
Heres my code :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If CheckBox1.Checked = True And CheckBox2.Checked = False Then
Timer1.Start()
ElseIf CheckBox1.Checked = False And CheckBox2.Checked = True Then
