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.

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.

View 1 RepliesI have a button on a form that is supposed to run an executable (compiled Intel Fortran v11) on the click event. Here is the code:
Private Sub RunButton_Click() Handles RunButton.Click
Try
System.Diagnostics.Process.Start("C: estDir estCode.exe")

I'm certain the path is correct and I have verified that running the testCode.exe from the cmd window works as it should (testCode.out file is updated). When I try to run the process via the RunButton it appears to work...no errors are reported or caught. However, the expected output file is not updated indicating testCode.exe did not execute. All of the online support I have researched indicates this should work.

I am using Compact Framework 3.5 on a Symbol MC50.In my Sub Main it first checks to see if a database exists. If it does, it shows a login screen using the following code:
Dim login As frmLogin = New frmLogin()
If login.ShowDialog() = DialogResult.OK Then
Application.Run(New frmMain())
End If
This all works correctly and, when I close frmMain, it exits the application as expected.However, if the database check in Sub Main fails, I call the ShowDialog() method of another form that is used to create and fill the database from a live server. Here is the code for calling this form:
If Not File.Exists(SETTINGS_LOCALDB) Then
databaseExists = False
MessageBox.Show("Local DB does not exist. The database must be created before using the application.")[code].....
All of this code is being hit and frmMain does indeed load. However, when I click the close button in the top right nothing happens, no event occurs. Its as though the Windows events are not occurring.

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?

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 need to send some keys in way like it was sent from keybord
View 1 RepliesI 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...

is there something wrong with this? its not sending the key
Dim inputEvents As New USER32.INPUT
inputEvents.ki.wVk = Convert.ToInt16(key)
inputEvents.ki.wScan = 0
inputEvents.ki.time = 0
inputEvents.ki.dwExtraInfo = IntPtr.Zero

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.
View 1 RepliesI 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?
View 7 RepliesI 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 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

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

View 7 RepliesDLLs in .net are treated differently than in C++ and other programming languages.When you create a class library project in VS (for either VB or C#) you are creating a DLL. In order to call/use that DLL in another project you have to add a reference to your new program.Go to Project > Add Reference..., or right-click on the project that needs to use your DLL, and click "Add Reference...".
After a short wait you should see an Add Reference dialog box.There are several tabs across the top but each of the components that is listed in a tab represents a DLL. If you expand the "Path" column in the .Net tab you will see the DLL location.If your two projects are in the same solution, you should probably go to the Projects tab and add the project that you need.If your dll project is NOT in the same solution as your project that needs to use the dll, then go to the Browse tab and find your compiled DLL from your DLL project. This will add the DLL as a reference to your solution.
