GroupBox_Enter Reports Previous GroupBox As Having Focus When Using Tab - Works Ok With Mouse Clicks
Mar 6, 2012
I have 3 group boxes on a form. Each group box contains a single Button and several RadioButtons - each RadioButton has an associated TextBox control. Changing RadioButton in a given GroupBox enables or disables the associated TextBox control in that GroupBox. There is also a RichTextBox on the form and the contents of the RichTextBox change depending on which GroupBox contains the active control.
I am trying to use the GroupBox_Enter event to cause the RichTextBox content to be updated. When the user uses a mouse click to move to a new GroupBox the RichTextBox changes as expected (desired) but if the user tabs from the last control in the prior GroupBox to the first control in the new GroupBox it doesn't, it gets stuck one GroupBox behind. This is the code:

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.

I have a form with few text boxes and other control on it like button etc. On click of a button on form i do some validation (like x = 2) if yes then it gives warning message and i want to give the focus back to the previous control (the control which was having focus before clicking button). I tried following on click of button
dim prevcntrl as control = asctivecontrol
if x = 2 then
Magbox("not valid")
activecontrol = prevcntrl

In VS2010 I'm encountering a PInvokeStackImbalance error when I call an unmanaged C function that takes a string argument. This only happens in VS2010 (works fine in earlier versions of vs). I know the MDA is more strict in VS2010 but I can't seem to figure out what the actual problem is.

If a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _
Handles DataGridViewPayments.CellValidating
[Code].....
Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.

I need to detect whenever user clicks the mouse, no matter what form is selected at the given time.
I know that detected keypresses globally can be done through a Keyboard hook so I assume that i am going to need some sort of Mouse Hook.

I have an application in Visual Basic Express 2008 that just has a Windows Media Player control on a blank form. In order to prevent the user from double clicking which would result in the media player full screening, I want to disable both right and left mouse clicks on the form and Windows Media Player control. Any suggestions?

I use pictureboxes on my GUI for click controls. The associated function will be executed whenever user clicks the picturebox control.
My question is that, how do I discard(not just suppress) a control click (message) for a period of time (i.e. during the function execution).
I simple just want the click messages made during the function execution discarded by VB.

hello,
i'm trying to build a application for my buddy who plays online games and has asked for a simple program to click the mouse button within his game that he plays for a certain amount of time with a certain duration between. my questions comes ( and i searched but didnt find much useful information for .net framework anyway) about how to detect a combination of keystrokes to start an action and further more to send a click event to the game that should be main focus. i'd also appreciate any tutorials on sending information to other forms controls etc.
thank you for any help

How would I make my VB Program detect mouse clicks? I want the code in a timer. So if I turn the timer on, my program will detect a Mouse click and then do the rest of the Timer code. And after the timer code is done, I want it to do it again until the timer is closed. So if the timer is on, every time I click the mouse, (anywhere on screen) it will do the rest of timer code.

How would I go about saving a persons mouse click. Here is how I would like my program to work: They open my program. They go into their program they want to record mouse clicks on, and they press F9. They click however many times, and it records each mouse click. They press F10 to stop recording. They can choose the delay, in milliseconds, between each mouse click. They get the data in a text box. They can save this info in a text file and use it alter if they want to, to play it back.

I have scoured the net for help with this problem of temporarily disabling mouse clicks on a VB Net form and have not been able to find a solution that works.
I'd like to prevent users form clicking on a form when i'm doing some background processing. To me it sounds simple in theory but apparently its not.

I have a process that takes 3 seconds which needs to be run when someone clicks or mouse-up on a specific date on the monthly calendar. However, I do not want the process to run as one moves from month to month by clicking on the arrow keys.
I have tried the date-change and mouse-up events and both of these fire when I move between the months.

I am new to VB.net, i did a course in it about 5 years ago, and could do simple programs, but lost most of my knowledge, because i have not used it in such a long time, now i want to do something and cant seem to get it right, i have this game that i a play online, and i have a few accounts for it, so i would like to make a account logger, wher the usernames and passwords will be saved in a text file, and then i just open the vb program, select the username and the vb program will automatically set focus to the game window (which is windowed, not full screen).
Problem is just, the game client has 4 buttons, New Account, Play Game, About and Credits, i want to get a way for the VB program to set focus to the program(bring it to front, and then move the mouse to the coordinates of the play game button, goto coordinates of the username text box, click and write the username, same for password and then move to login button coordinates and click logon, wait a sec or two and move to either character 1, 2, 3's login button and click)
