Is there an event that fires in vb.net just before a contextMenuStrip appears when the user right clicks on a control? I need to be able to control the content of the contextMenuStrip just prior to the menu strip appearing. Basically I want to be able to change the content of the contextMenuStrip just before it appears.

I have a contextmenustrip containing a datetimepicker. Now the problem is that when I choose another date in the datetimepicker the event for that goes through without a problem BUT the event causes the contextmenustrip to go away. The problem is the contextmenustrip must stay shown. I solved the issue with contextmenustrip.show on the end of the event, this works but this has one big disadvantage. I loose all information about the sourcecontrol of the contextmenustrip, and this can't happen.A monthcalendar lets the contextmenustrip stay after his event, but a monthcalendar is too big what cause my menu to be clumsy.
View 2 RepliesI have single ContextMenuStrip attached to more controls.In use the Opening event of ContextMenuStrip to filter/disable some context entries.In this case the property ContexteMenuStrip.SourceControl is set correctly.The problem I have is on the Click event of a ToolStripMenuItem. This item is inside a ToolStripDropDown. I get the parent item with code:
Dim tsmi As ToolStripMenuItem = DirectCast(DirectCast(DirectCast(sender, ToolStripMenuItem).Owner, ToolStripDropDown).OwnerItem, ToolStripMenuItem)

How do you deactivate the ContextMenuStrip when you right click your mouse. Because I have a checkbox that the ContextMenuStrip will not display if it is not check.. If it is check, the ContextMenuStrip will be activate again.

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 solution in Vb.NET 2008 windows Form with ToolStripMenuItems, but I need to implement menu navigation without any mouse intervention.I only found mouse events In ToolStripMenuItems, MenuStrip, etc.All MenuStrip and ToolStripMenuItems are created programatically, reading user permissions from Database, then add a handler to manage the events, but the client don't want mouse interaction, he wants only keyboard inputs only ![code]

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?

View 3 RepliesI have a windows form that can search for data and the results are results are returned in a Datagridview. The Datagridview is bound to a custom datatable object. On the CellDoubleClick and CellContentDoubleClick events, a new form is supposed to open which will display the results of that row. What I am noticing is that the datagridview doesn't always fire when I immediately double-click on a particular row. It would appear that I have to first click on the row to "select" it, then double-click the row so the event will fire. Is there a way to remove this intermediate "select" step? Is there a property in the Datagridview that needs to be activated so the double-click events will fire right away? Does something possibly need to be done in another DatagridView event?

View 11 RepliesI have multiple textboxes which I want them to perform the same thing upon clicking them. By default I can use the handles textbox1.click for 1 single textbox as shown below but I am not sure how to do handle multiples of them.

View 4 RepliesIs it possible to have multiple click events for a button based on the button text? In other words, if I change the button text can i create a new click event based on that text but use the same button?
for example:
button1.text starts as "steel"
button2.text starts as "brass"
If I click button1 then the text would change to:
button1.text="Stainless"
button2.text="Cold rolled"
If I click button1 again a string would then be added to a textbox and the process would start over again. can I have a different click event or would I need to put an If/Then or Select/Case in the sub to handle this? I have 10 buttons I would need to do this with and each needing at least 3 different choices for each depending on the previous button press.

Attaching code to buttons when they're clicked is easy when they're static buttons on the form; just double click the button on the form designer and add code to the event.
I have a series of buttons that are generated in a control array, so they're generated in a class, and in the form there are no buttons until runtime.
So newbie question with a probably simple answer...how do I enter code for the click event for buttons that aren't there until they're instantiated as a class at runtime?
what are some helpfull source codes to set button click events and to use them to open uther programs .
View 1 RepliesMy program's code is getting a bit jumbled with all the subroutines for button clicks, etc. I want to move them into a more manageable set of modules, but I get the following compile error:

Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
For each event. Clearly I have to define a WithEvents variable, but I have no idea how or where to.
My problem is: i can't enable the mouse events like click under my custon control.this control is a simple container, with a image and a label.

In my application, every time a button is pressed a complex interface is built, it requires few seconds to be built.All works well till someone press the button too quickly and the application lag behind.Is there a way to read how manu times a button has been pressed so I can jump to build the last interface number equivalet to the sum of the last few click avaoind to try to build the interfaces in the middle.
View 7 RepliesI am trying to put a new face on an old C program. The C program is, of course, unmanaged code, designed smartly to separate the number crunching and the interface, and the interface I'm trying to replace is X windowing. The graphics part is where it gets a little hairy, because the C is going to need to continue to draw in my new interface, based on the data the program produces. Even if I want to duplicate that data in .NET so that the .NET side can handle all of the drawing, the fact remains I'm going to need to operate on the graphics window in some fashion from C.
I gather that handles have a lot to do with the bare Win32 graphic operations. Is such a similar handle provided to, say, a PictureBox element in .NET? And if so, is it the kind of handle I can use in the unmanaged code without an issue?
I have tried and tried and tried to google for the solution for weeks now, and all I come up with are either C++ solutions (using object-oriented GDI+) or some sort of extension to the C language.
Alternatively, is there a way I can have .NET create a handle specifically for this purpose of having C draw it?
To sum it up, I am using Visual Basic .NET 2008 and a C DLL (also compiled in VS2008), so far in the little testing I've done, I've been able to marshal complex structures to and fro, but I am not sure how exactly I'd let C do any drawing on the .NET form, if that was even possible.

View 1 RepliesAnyways, after thorough researching as much about context menu, I have tried to do a left and right click context menu, including the events that will happen by opening the context menu. I wanted this to happen on a specific place, not the form itself (In this case, a picture).The left click context menu works fine, but when I try a right click context menu, the left click context menu will pop-up as soon as I release the right click button.[code]By using this code, I have a small nuisance of the right click event, where when released, it also uses the left click event. Any ideas of how to, well, stop it opening the left click menu when I release the right click button?Alternatively, I was thinking of using a mouse hover event to replace the right click event, but I'm not that advanced of a programmer.
