Hook Into The Mouse Click On A Command Button?
Feb 24, 2011
I need to write an application that can validate wether or not a proper process was followed based on information that was entered into another .NET appliction. Basically, I need to be able to intercept a mouse click on a button in another application so that instead of submitting the data it triggers my validation code then cancel the action if need be.
We do not have the code to the other application. I have everything I need perform the validation. The only thing I don't know how to do is intercept the mouse click on the button control of the other application. Can some one show me how this is done?

I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.

I am writing an Automation program to control an MS Acces applcation. Here is the sequence of events:
- Load MS Access Database (Done)
- Load an MS Access form (Done)
- Take dates from Main.VB and populate 2 fields in MS Access form (done)
- Load another MS Access form called Stage_2 (Done)
- Load a file name into a filed in the Stage_2 form (Done)
- Do a click event in MS Access linked to a button called Pre_Stage_copy on Stage_2 form (How do I do these?)
- Do a click event in MS Access linked to a button called Pre_Stage_import on Stage_2 form (How do I do these?)

I have a form that is displayed, not by ShowDialog, but by setting its visible property to true. This is so it behaves like a dropdown.The form installs a mouse hook, using SetWindowsHookEx(WH_MOUSE, ...).
I detect if the mouse is clicked outside of the dropdown and if so, return 1 in my HookProc method and close the dropdown.The strange thing is, if I click outside of my drop down on to a textbox, the textbox still receives the mouse click, after my dropdown closes, even though it's been handled by my HookProc method.It gets stranger... If I click on a label or button, they do not receive the mouse click, as expected, after the drop down closes!

Using VB 2010, is it possible to capture all mouse clicks and determine what was clicked?We're trying to develop a small utility that will pop up context based menus to fill in application forms and common strings for terminal sessions.Basically, whenever I middle click I want my app to determine if the window was an occurance of PuTTY. If so, check the titlebar for certain strings and send keystrokes to that window based on the titlebar text.If VB 2010 can't do this, what should I be looking for? Will VB6 apps do the job? Will they work on a Windows 7 PC?

I have a form, that acts like a drop-down, that I display non-modal. I attach a mouse hook to the form to determine when the mouse is clicked out of it, so that I know to close it - by setting Visible = False.
Because I want the HookProc to handle the last click, I can't dispose the Hook or my Dropdown until I'm sure that my event handler has returned to the HookProc.[code]...

I need to visually moves the cursor using keyboard keys.
1) I need to get the mouse to where the button is
2) Simulate the mouse movement to the button from whereever it is
3) and simulate a button click.
Only after I select a button I can start drawing on my form. I have a code here, when I hold the Ctrl key and press the arrow keys, the mouse will start drawing straight lines. But what happen when I need to use controls like buttons, comboboxes etc.?

I'm using code from here - [URL]. And I'm getting the old
A call to PInvoke function 'EliteSwitch!EliteSwitch.MouseHook::CallNextHookEx' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Error on this line
Return CallNextHookEx(MouseHook, nCode, wParam, lParam)
I've tried changing variable types but I can't get it.

It was pretty simple in VB6 to invoke the 'click' event of a command button (i.e.; btnNext_Click). I am having difficulty trying to do the same think in VS2008.
I am getting errors at line btnNext_Click(): Error1Argument not specified for parameter 'e' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
Error2Argument not specified for parameter 'sender' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.

I looked at "How do I place an image with a mouse-click in Javascript?" but it had a small snippet of Java; immensely larger than my knowledge of Java. And that is the closest I've come to finding an answer in the past week. Here's what I would like to do (don't know if its even possible):
I have a panel and a toolstrip with 3 buttons. Each button represents a different image. I want to click on a button (once) and then move into the panel and everytime I click the mouse button it drops the image where ever I clicked. This only ends when either I click back on the same button or one of the other buttons. I do not want to drag an image into the panel each time. In other words the button stays depressed and the event/action stays active.

Is it possible with API to see what file is being clicked on with the mouse globally?
Ex: On desktop(or anywhere), mouse clicks a folder/file. <The below part would be easy,considering I would already have the above> Usage - A label generates the folder name/file name.
I thought maybe that the DragQueryFile Function would suffice. But, I think that is geared towards a drag and drop operation from with in a .net form.

I have a problem. When I play a wav file using winmm, as soon as I click on a different command button on the form, the audio playback stops. How do I make sure the wav files are allowed to play in their entirety even when focus is moved to another control?

I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part.
I am using the (I assume pretty widely used) following code for Global Hooking of the mouse.

I am trying to write a program using Visual Basic 2008 Express Edition that will automaticlay generate multiple Command Buttons that have different Texts and perform different commands.For example I want to generate Button_1 and Button_2 where Button_1 when clicked enters the value "1" into a textbox and Button_2 enters the value "2" into the same textbox.I know this can be simple done by using the designer and wirting the code in the Button_1_Click, but what I want to eventually achieve is for various buttons to be generated across different Tabs in a TabControl.So far I can create a button on a windows form using code, but the button has no purpose so command is assigned to it. The code i've used is listed below:

I have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.

Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.

I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.

Im using Visual Basic 2008 Express..Is there a way to disable mouse click for a while in Visual Basic 2008, I mean if mouse was clicked more than 1 time in very short time to click only once? -- I need it because my mouse became like crazy one.. when I click once it may clicks twice or more.so until I buy another one, I'd like to filter click, to allow only one click and to block another clicks that were made in last second.
