Do not use such a confusing naming of your variables! When I read Item**s**, I expect some kind of a collection/array. And better use a Class instead of a Structure. In your ChangeItem function, you must retrieve the item from the listview, and then change its properties.

Same way as a UserControl? The example on MSDN[^] uses a Button from WPF, so I assume it's not limited to UserControls. Bastard Programmer from Hell :suss: If you can't read my code, try converting it here[^]

Check this article out ... I think you should be using a different method to manipulate the Access data. I have been using the System.Data.OleDb classes for MS-Access and they work fine. http://msdn.microsoft.com/en-us/library/ms971491.aspx[^] Remeber to vote.

I want to run any action given by user. Not only resize image.

SYSTEM/Hardware/USB -HUD devices reveals the identity. Use this ID to communicate via USB. Interesting Velleman project K8055_VB communicates with an experimenting board, has VB source. Uses C-DLL, however which does not reveal code. VB-source to locate, open-close, read write USB devices in VB is out there too. :cool:

Good Alternative.

It's working. thanks a lot. :)

That depends on the SQL query you used to get the data. Let's see it. Chances are, you're probably not using a LEFT OUTER JOIN to get all the records on the Customer side of the join. BTW, this has nothing to do with VB.NET... A guide to posting questions on CodeProject[^] Dave Kreskowiak

All you're doing is converting the new keycode to an Integer and passing the new value to the CallNextHookEx function. Seriously, why is this so hard? A guide to posting questions on CodeProject[^] Dave Kreskowiak

Thank you so much. Now i can understand it

Yes, this is possible in most circumstances. The first problem is in identifying which window you care about. Multiple applications can have text selected at the same time. You can make clever use of FindWindow() and FindWindowEx() to get a handle to the window in question. The second problem is in identifying the GUI element on that window that might have text that you are interested in. This is actually a much more complicated problem since the GUI element could be any sort of object, nested anywhere on the window. You could use GetWindow() to help with this. The third problem is telling what text is selected within that GUI element. The way you do this depends on the GUI element in question. In a few cases, it may not even be possible. I'm not really sure where I would begin to try to crack that nut. There are a ton of useful API calls that you can use at http://msdn.microsoft.com/en-us/library/ff468919%28v=VS.85%29.aspx[^] You might almost be better off thinking about this problem differently. You could, for example, set up some global system hooks to capture the relevant mouse and keyboard events that occur when text is selected. Then, you would have immediate and direct insight into the objects with which you were dealing. Read this article for an idea of where to start with that approach: Global System Hooks in .NET[^] Good luck.

I once heard tell of a tale where this magical genie could answer all your questions by providing you "links" to different "sites" with vast amounts of writing in a strange language called "HTML". That writing would have all of the information you could possibly desire. Sounded strange to me. "links"? like in a chain? "sites"? is that like it would magically take you to Abu Dhabi somehow using that chain? And "HTML" sounds like alien talk to me. I wish I could find that genie. Apparently there were two of them...one named "Larry Page" and one named "Sergey Brin".

It's message is "Cross-thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on." You can achieve this very easily using the background worker class (http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.aspx[^]). Just enable progress change and supports cancellation on the background worker object. Then, in the Do_Work sub, report progress, and you can easily update your progressbar in the progresschanged event. Hope this helps. He who goes for revenge must first dig two graves.

You still struggling with this one? When you say insert method presumably you are executing a method to insert the data into the database. If you want to undo that insert it is called a delete. The data has been written to the database, unless you write code in the undo event to delete the record then how do you expect to achieve this. Never having used the undo method I am guessing here but I would assume the undo method implements a short term cache in the local memory with the ability to step through a list of changes, restoring each subsequent change to the text property of the control. Nothing to do with insert! Never underestimate the power of human stupidity RAH

It helps to read the documentation on the TextBox class. Undo has already been implemented. CanUndo tells you if the last operation the user did in the TextBox can be undone or not. It does NOT enable or disable the Undo functionality of the TextBox. In whatever code you have that lets the user command an undo, you have to check the CanUndo property of the TextBox and then, if true, call the Undo method of the TextBox. You would also look into calling the ClearUndo method if appropriate in your situation.

Char.ConvertToUtf32. That gives it back as an integer, then just format it.

The KeyPress event passses a KeyPressEventArgs which holds the KeyChar, i.e. the char that the user intends when he types a key or key combination that produces some text. This is the event you should use to consume text input. The KeyDown and KeyUp events also fire for key actions that don't produce visible text, such as the control key. They hold a KeyEventArgs that has all possible information about a key and the key modifiers. These are the events you could use to filter keyboard input. BTW: Control.ModifierKeys is always up to date, but seldom needed. PS: is something wrong with the documentation? did Google break down?
