This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?

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.
View 2 RepliesI need to draw lines each time a mouse moves over teh form....
currently i use the Mouse_Move( ) event, this caputures my mouse moves. and it creats lines. But i need to draw those lines on to the form.
This lines are not drawn when form_laod() fires that will trigger OnPaint(). Te lines must be drawn to the form when the mouse moves over the form.
How do i do this? I currently know how to capture the points evenry time mouse moves but i dont know how to draw the lines each time mouse moves. this is because im in dount of the event that i have to use.
My main form is a tabbed control with 2 tabs. The first tab is has two listview controls which display information about the current machine. The second tab contains a treeview control and two listview controls. This tab recreates the device manager in windows. I created a Machine class to gather the information about the machine that I want to display to the user. When I call the Display() Method from my form's load event everything appears to be fine the first tab's information is displayed in the listview controls.
Here's the kicker, when I click to the device manager tab there's nothing there. The LoadTree() procedure never fires. This code works, I've seen my device tree display a thousand times in the past. When I comment out the call to Machine.Display() my device tree reappears no problem. The code compiles fine no errors. I know the problem has to be in my Machine class but I have no idea what could cause this kind of response. I've never seen a program compile clean and then refuse to fire a procedure call but not produce some kind of runtime error.
I have a unique challenge that I just cannot seem to get by...I have a form with a series of listboxes that allows the user to rename items in the listbox (I probably should be using a listview control instead). When the user right-clicks and selects rename from the context menu I show a simple form with two labels & text boxes showing the selected list box item in one textbox...the other is blank waiting for the user to enter a new name. What I'd like to do is when the user closes the rename form, the information is passed back to the calling form and a listbox refresh method is fired to show the changed name. Couple question:
First, is there an easier method to implement the renaming concept in a listbox (probably should be using a list view) i.e., have I overcomplicated things?

View 2 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.

This is what I'm looking for however, paired with the ability to simulate the click while not being on that form. I believe this would require the coordinates to be relative to the form itself also. I'm not sure if this is all possible in Visual Basic, however I've seen it utilized in Actionscript and Java.

I'm working on a custom scroll bar. When dragging the slider, things work smoothing with what I have... that is if the users movements are smooth and slow-ish. When moving quickly the mouse move event doesn't seem to fire as accurately as I had hoped.. I attempted using the up and down buttons enter event for re positioning or "resetting" the slider whenragging is activated but still those events don't even fire when the mouse move event is firing. So I believe I hit a barrier of my .Net knowledge and hope someone here knows a way around this little issue.
