I have some code in a label's mousemove event that allows it to be dragged around my form while the left button is held down. While this is happening none of the other controls on the form respond to their own mousemove events as the mouse pointer passes over them. Is it possible to make more than one control respond to mousemove events at the same time?

I have a datagridview which is populated from a database. I have added buttons to this to edit, view, delete. For some reason using the edit button and updating the database my grid fails to respond. I have it set up to display an image based on the row I click on. Before the update this works, after is does not. After the update I run a reload() where I clear out the dataset and repopulate the datagridview. Here is the code I am using for the reload and the update.

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 do we make a visual basic listbox to respond directly when the user clicks on the items in the textbox? (such as making a menu appear or displaying info in a label when the items are clicked)
I have used the SelectedIndexChange event but nothing happens when the listbox items are clicked. The SelectedIndexChange event only seems to work when a button is added. It seems that the button's click event gets the listbox's selectedindex change event to start working. The listbox's textchanged event doesnt seem to work also.
Is there any way to make the listbox respond directly to the user's clicks without the use of button controls?
I am working on a project which will be installed in Embedded pc which won't have mouse and keyboard. Works with touch screen. I have an option in my software to make calls.I need to have an option like Push to talk. When need to talk they need to push the button and when they release they can't talk. Something like walkie talkie concept. The embedded pc where my software will be installed will have touch screen. How can I do this??
I tried to write my code in button click event and when they take out the mouse from the button, I am stopping voice. But, that is not I want. I need to push to talk and release after talk.

View 2 RepliesI have a form with 2 contols that I with to connect by drawing a "wire" on the screen. It goes like this: you mouse down on the first control then move the mouse while holding the mouse button down. When the mouse is over the 2nd control the mouse button is released and the controls are wired.
So I am playing with mouseup, down, move, etc. When the mouse is over the first control I get mouse moves from that control, but when it moves off the events stop, and I get no events from the form even though the mouse is there.
Is there a way to do this? I have seen it done in a Java app. I could brute force it and just draw a box on the form instead of a control, but that sounds like a step back.
Normally the event: PanelTransparentMarquee_MouseUp is only raised when the mouse is within the PanelTransparentMarquee panel. I'd like it raised where ever the mouse is on the screen.So in the load event for the usercontraol containing

PanelTransparentMarquee.Capture =
True
But I still only get the PanelTransparentMarquee_MouseUp event when the mouse is within the PanelTransparentMarquee panel.

I've got a NotifyIcon that signals downloadable application updates. I want the download page to open on a Left Click on the NotifyIcon and on a Left Click on the NotifyIcon balloon (on screen for 10 seconds). However, when I handle the BalloonTipClicked event I can't figure out if it was a Left or a Right click. Thus, while the balloon is still on screen and the user Right clicks on the icon, I get both the popup menu and the download page opening. How do I detect the Right mouse button was used?

View 16 RepliesI'm working on a grid of cells that is something like a DataGridView, but not really. The two are close enough that you can picture a DGV for the purpose of this question. What is actually there (and this is true for actual DGVs) is a set of cells drawn on the screen with a couple scrollbars for vertical and horizontal scrolling which are only drawn if there is too much data to show in the visible cells. There aren't more cells than the ones that are visible, so when you scroll the scroll bar, it looks like new cells are being displayed, but what is actually happening is that the existing cells are just being filled with different data depending on the position of the scrollbar. The key observation is that the set of controls displayed in the grid is always the same (unless the grid is re-sized, but that's not relevant to this issue). The appearance of those controls can change, but the controls themselves do not.
One of the features I am adding is the ability to drag-copy data similar to how Excel works. In my case, if you click on a cell, then drag outward (move the mouse while holding the button down), all the cells in the selection rectangle are tinted green. This works nicely. Some of the cells are enabled, while others are disabled. If the drag selection includes disabled cells, those are not tinted. Only enabled cells can be selected, though a drag can cover disabled cells. The relevant point here is that some cells are enabled and some are disabled.
The feature that I am adding is the ability to do drag selection beyond the visible edge of the grid. The grid is a monthly calendar, and I simply can't get 31 cells onto even a wide-format screen. What I am trying to do is allow the user to do drag-copy onto days that are not currently visible. The way I do this, the user clicks in a cell, then drags out to the border, at which point the grid scrolls (the scrollbars move, and the contents of the cells is updated as a result of the changes to the scrollbar value). This is largely working.
The way I handle the selection is that when the user presses the mouse button while over a cell, a flag is set to indicate that the button was pressed, and the current cell is recorded (so that I know where I started from). MouseMove events are used to figure out what new cells the user has visited, and set the selection area based on whatever is under the rectangle described by the initial click point and the current point. Lastly, when the user releases the mouse button, the MouseUp event initiates the actual copy. At that event, I know that the user is done with that copy action. Therefore, the MouseUp event is kind of critical, and therein lies the problem.
As I mentioned, some of the cells are disabled and some are enabled. Disabled controls don't raise events. If I click on a cell, it HAS to be enabled, but that's fine. The problem is that if I then move the mouse in such a fashion that the grid scrolls such that the cell that I had initially clicked on is no longer enabled, then the cell doesn't raise events any more, and the MouseMove and MouseUp events stop happening.I only see one viable solution, which is to not toggle the enabled state of the grid cells. Instead, I would have to have to add a custom property that would make the control act and look disabled as far as the user was concerned, but it wouldn't be disabled as far as the program was concerned such that it would keep raising mouse events. This would be pretty rough, since I would need to prevent the control from appearing to have focus even though it technically would have focus
How can I use mouse events to move and click my mouse in another window.

I'm trying to make a way to navigate around a custom grid. Basically, I'm implementing the drag-copy feature from Excel. Right now, you click on a cell grid and can drag around the grid. Anything in the drag area gets a green tint. Once you release the mouse button, whatever was in the first cell selected is copied to all the others that are tinted. That works pretty nicely, but it works only for the cells visible on the screen. I can live with that, but decided that if you dragged over the scroll bars or the column or row headers,then the grid should scroll (if there is anywhere to scroll).
That's where the problem arose. It turns out that scrollbars don't raise the MouseMove event (at least not as far as I can see), and the MouseEnter and MouseHover events are not fired as long as the mouse button is held. Interestingly, the MouseLeave event does occur when the mouse button is held, just as the MouseMove event is occuring for all the cells. That's pretty annoying. Why do some mouse events get raised when the mouse button is down while the others don't? Also, I suppose, is there any way around this?
I have set the controls mouse enter and mouse leave events. My problem is that the mouse leave event fires if I mouse over any of the child controls (like the name box for example).What I need is for the mouse leave event to fire when my mouse leaves the entire control, rather than firing when I mouse over any of the child controls. Here are the events as I have them so far:
Private Sub DeliveryControl_MouseEnter(sender As System.Object, e As System.EventArgs) Handles MyBase.MouseEnter
Me.removeImage.Visible = True
End Sub

First, I want to know if the mouse is in some area. Then, I want to check if the mouse holds the left click. I want to check as long as the left button is down, and I want to track the mouse's position. And finally, check when the left button is released.
So, in short, where should I start for tracking mouse events in my form?
