Detecting Mouse Wheel Events When Form Does Not Have Focus In Visual Basic 2010
Aug 11, 2011
I want to make an auto log off feature, I want to detect if there is any user input, and if there isn't the user will be automatically logged off. So I want to know how to detect mouse wheel events when the form doesn't have focus.
how to capture the mouse wheel if the mouse is directly over my control - regardless of what form / control has focus?? - however if another window or control is over the control at the time it won't scroll.
i have use one mdi form and with in i have call form1. in mdi there is menu and text box.when i run program the mouse wheel work in form1. but when i click on text box after it only mouse wheel not work on form1.
The GetAsyncKeyState Api does'nt recognizes the mouse wheel rotation, I see.Is there way to control the mouse wheel rotation (always, not only when the pointer is over a form of mine) with a simple API, without to Hook the mouse?
I display a Chart with several graphic lines on it. What I want to do is draw a line (using the mouse) overtop or below the chart such that it can be seen on the chart. The mouse line draw code is below. What is required is either make the line always be on top or make the chart transparent. I don't know how to do either and I don't know if it is possible in Visual Basic 2010 as it was in VB2.
Private Sub frmComDashBrdGraph_MouseDown(ByVal sender As System.Object, _ ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown If e.Button = Windows.Forms.MouseButtons.Left Then
I have a Richtextbox and I would Like the user of the program to be able to drag and drog the richtextbox in other specified places in the program.
I have this very basic
Private blnLifting As Boolean = False Private Sub richTextBox4_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox4.MouseDown
[Code]....
Firstly its very inaccurate. I want it so the Richtextbox moves with the mouse and not after the mouse. So I want a smooth drag and drog.
So I don't know if this is the wrong code for something that I want perfect like that.
Secondly I dont know if its possible but I would like it so the box can only be dropped in certain area's in my program and if there is a box already occupying that space, It goes back to where it was before.
I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.
how to make a layered form (im a begginer!). I've found something about calling API, but that sounded like old; cant I do this with .Net? If api is necessary, with that hwnd thing, how do I call it? And if you are so kind, is there a way to search for thing only for visual basic .net 2010? Because i dont find a way to practice a strict filter, and visual basic 6, or old visual basic stuff (if not other languages) appear mixed with the program i use.
I have a Booking Form and a Daily Jobs Form. and when the Booking Form TextBoxes And ComboBoxes have been filled with the relevant Data/Text. And when I click the BtnSave I want to UpDate Daily Jobs Form, DataRepeater1 with some of the TextBoxes And ComboBoxes.
With the DataRepeater1 I have Dragged And Dropped some of the TextBoxes and ComboBox From The DataSource Booking Form that I require. But Now This is where I am Stuck. do I write code for DataRepeater1 in the Booking Form Code or Do I write Code in the Daily Jobs Form, DataRepeater1. code.And How would I start the Code. I have looked at some walkthroughs and Video. But i cant seem to adapt the code to my requirements
how do I make a textbox that counts every single mouse click made while the application is open?
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal VKey As Long) As Integer Private Sub WebBrowser1_MouseDown(ByVal Button As Integer) Select Case Button
This is well documented and easy to accomplish in Access, but how does one accomplish this in Visual Basic 2010 on a form designed in Visual Studio that is bound to a SQL Server database?
The idea is to create a combobox that holds 2 columns - a primary key value and a unique value such as a [Company Name] or a [Student Name]. The user would then find the appropriate record within the combobox and the code behind the combobox control would then perform a .findfirst method that would NOT filter out all other records, but would rather use selectedvalue primary key column value to move to the selected record.
I am currently getting into VS 2010 & revisiting VB having been programing in ACCESS & VBA for years. In the Access/VBA environment it is very common to have to find a given record on a given form using this method, but it would appear to be poorly documented if in fact not commonly used in the VB.NET/VS community.

I want to programmatically set the focus to the last row (bottommost, its only one column wide) in the DataGridView control for Visual Basic. How can I do so?
So far, I have tried DGV.Rows.GetLastRow(DataGridViewElementStates.Selected)
without success, though I did not expect that to work. It absolutely must select that last cell. Otherwise, the application is nearly impossible to use!
Here is a screenshot of what I am making with this: [URL]..The "Paste Clipboard Contents" button only pastes into the selected cell, though I guess I could find a workaround.
I am creating an application that creates scripts to move a mouse and to click where a user wishes to via pre-programmed code and to also press keys where required. I have the code to move a mouse and to manually click anywhere. What I am after is to detect when a mouse button is pressed and dragged and when keys are pressed.
I see that there is the following MouseButtons.ToString To detect when a mouse button is pressed, and have it looping in a timer. Is there a better way to do this? I would rather not use a timer. And is there a similar routine to detect which keys are pressed?
Is there any way of detecting the position where the Mouse Button is released during a Drag & Drop operation. I need to know whether the intended Drop position was not reached when the mouse button is released.
I have a vb.net application, and I want to know how to find the coordinates of the pointer (mouse) when it is clicked on the form. Not much else to say, so I'll leave it like that.
I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.
Imports System.Runtime.InteropServices Imports System.Windows.Forms Module Module1 Sub Main() Dim t As New MouseHook
A form's key events will fire when you press a key. Place a control on that form and it won't happen any more because that control has focus. There are exceptions to this however as you will see if you place just a h or v scrollbar on the form. The key event will fire because the scrollbars can't receive focus as is demonstrated by the following
Private Sub ScrollBar1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles VScrollBar1.GotFocus Debug.Print("Scroll GF") End Sub
[code]....
So I've made my own special scrollbar usercontrol and i can't figure out how to have it leave the key events alone. I'm pretty sure that the problem is that my usercontrol can receive focus at the moment.
I found that the way of doing this is "SetStyle(Windows.Forms.ControlStyles.Selectable, False)". I put that in the new event of my usercontrol and now it looks like this:
Public Sub New() ' This call is required by the designer. InitializeComponent()
Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.

i have two Forms. The first one is my Main Form and the second one my Child Form. From the menu in Form1 i open Form2, butnot as ShowDialog(). After showing Form2 this form has the user can do something. But at the same time he is, and he msut due to application function, able to do something in Form1.Basically this works, but the problem is when the user klicks on Form2 on a Button and then he wants to clicks on a Button on Form1 he has to click two times1. time to set the focus for form12. time to click the button
Just a quick question my textbox1.text seems to get focus when I run the APP.how do I cancel any focus to any textbox?I just don't want to select it or anything when I work with it only when the user select or uses it.
I have a mdi form and two child forms ina VB.net application. When i load the mdi both of these child forms are shown, one of the form is in focus while other is not. Now the problem is if i clickon the body of the second form it does not get
