• Carl Bruneau Hot Key function for whole program

  Hi all Are there any good examples for a hot key class. I would like to implement hot key functionallity for the whole application I am creating standard text when user presses ALT or CTRL + F-key. Any links / urls you know of Lars E Thanks. That was great! But how do i get the keystate for onther keys accept Control, Shift and F. Where can i find the keystate for every funtion-key Thanks again. Lars E. The easiest way is to specify the same key-handler to every textbox you want it to work for. The alternative is to have a "windows wide" hotkey set, then apply it as it works, searching for the active control to put your text into, which I don't think you would like to do. ...Show All

• claydevin Control.OnMouseHover event

  I am writing a custom control that inherits directly from Control. While doing this I was overriding the default behavior of the OnMouseHover method in order to raise an event that I wanted to happen each time the mouse stopped moving. I ended up scrapping this after a while though because the behavior of the MouseHover event was not what I expected. What I expected was, each time the mouse is moved there would be a timer that is restarted and waits a set amount of time before it raises an event. I figured the amount of time it would wait would probably be the value stored in System.Windows.Forms.SystemInformation.MouseHoverTime. But when I would test my mouse hover events that were based on the default behavior I would only get i ...Show All

• Vasile Strange behavior with Navigation in BindingSource

  Hi, I got a problem. I have a BindingSource, connecting at my database to show me the data in my program, so I added 4 buttons to navigate, and I navigate using MoveFirst(), MoveNext(), MovePrevious and MoveLast, but what I noticed is that sometimes the method don't work as expected, this happens more when I edit some field. I don’t know what is happening but let's say that I have 6 items, so I edit item number 5, everything works fine and my database gets updated, but when I click the button to call the MoveNext() for example the field that is shown is not the right one, it goes to the item number 3 for example, so I need to click at MoveLast, and then everything comes back to normal. If I don't click at MoveLast it simple doesn't work ...Show All

• Nep23 Floating tool window

  I'm looking for a way to implement a C# form which hovers in the same manor as a C# floating toolbar, but my hovering form will never be docked. I'm hoping not to use the Interop functionality and do it all in .NET. For instance the Solution Explorer window in Visual Studio .NET if it is not docked to the IDE will hover/float above the IDE so the end user will always see it while Visual Studio .NET maintains focus. Once Visual Studio .NET loses focus to another application (for instance the standard windows calculator application) the other application window/windows will be on top and be able to hide the Solution Explorer window. I've tried using the TopMost property of a form but this is not a solution since it will keep my tool wi ...Show All
