Hi,
One of the users of my application is complaining that he can't open the application.
He gave me the debug output of the crashed application...unfortunately I'm not an expert and have difficulties to manage it...would you please give me some help and help me understand why the application is crashing on his system?
Thanks!!!

The most important part - as far as I am concerned.
Always deploy the PDB file with the application - this way you will get a decent stacktrace where it should tell you the exact line number on which the exception occured.
If you can do it re-deploy the application with the PDB file and get the user to do whatever they were doing previously to crash the application then post the results here and we may be able to help direct you to where to look.

You seem to be missing the most important part - the actual error message.

I have a Application In Vb.Net .I am Developing This Application on Microsoft Visual Studio 2008 , VB.NET, Sql Server 2005 , Crystal Report.
And That Application Have Registration Form . Now My Question Is
This Application is Installed On 5 different Computer In a Network . At the Mean time all 5 users
are Open Registration form Then They click on Save button on same time . I Have a table registration , and that has a column (code) that is primary key. whenever they want to save the record only one user can get save the record . all 4 users are rollback the transaction because of primary key violation error. Therefor i want to generate code on a queue basis .. where user can wait to get a Unique Code of that Record and i dont want to users request to rollback ...

Is the primary Key something generated by them?
does the primary key have a certain construction?

Yes Primary Key Is Generated By Our Store Procedure
Yes
|
|
|
|
|
But does it use some sort of business logic to create it?
i.e. (made up example)
Username = simonwhale
date registered = 30/09/13
primarykey = SE300913
or is it a incremented key?

|

ya also used business logic
i.e 2010090001
WHERE 2010 IS YEAR 09 IS MONTH 0001 IS INCREMENTED KEY
But in case of multiple user are click on save button that time generate primary key duplicate error
i want to response that request one by one by queue manner

There's your problem. Your key generation is not unique enough.
I would have a read of this and see if it helps you

That was a good hunt, but sounds like you shot the wrong one; sounds more like a concurrency problem than "not being unique enough". The sequence would be unique "enough", but concurrency-problems (a non-atomic operation) might cause the same number to be presented again.

I would like to know if anyone can give me an example of how to copy text underneath an external program's context menu.
I am playing around with code for basic mouse gestures. When I perform, for example an upwards movement with the right mouse button held in, my program send Ctrl+C to copy whatever is selected when I release the right mouse button. However, lets say I am trying to copy text selected in notepad, If I release the right mouse button over the notepad window, notepad pops up its context menu before my copy command can execute.
You can simulate this by selecting text in notepad, right click and while the contect menu is showing, try pressing ctrl+c.
I am looking for a way to copy what is selected in the foreground window without having to close the context menu. The reason I don't want to close the context menu is that at times you might actually need it, like when you right-click and drag a file in explorer. If my program would esc the context menu then explorer won't pop up a context menu to move or copy the file to where you dragged it.
I hope this makes sense.
Anyone?

With the context menu open, moving the pointer to "copy" does the same thing ... what is on clipboard ... arghh (brain frozen)
What are you trying to do? Better question, what VB.NET tools do you have available to you to use as a programming platform?
Are you refering to some sort of macro recorder by any chance. Recording mouse movement and behavioral clicks based upon what's on the screen for playback as a mouse behavior repeat in an overlay scenario?
There's this:

I can't programatically move the pointer as not all programs context menus will have the copy command at the same place.
What do you mean what VB.net tools do I have? I use visual studio 2012

"Underneath"?
What is underneath? Some sort of new technical term for "directly south"? I'm sorry, that was too facetious. Can't help you.

sorry, english is not my first language. I meant whatever is selected under the context menu

You cannot capture text just by moving the mouse over a window that belongs to a different application. As soon as you do that all mouse messages will be sent to the owner of that window, which in this case, is Notepad.

thanks to everybody who replied. I found a solution to the problem

would you share it with us?

I ended using a global mouse hook to perform (and draw) mouse gestures. That way I can call my own procedures when the right mouse button down/up event is fired

Hi everyone, I'm in need of a bit of guidance. I'm working on a little weather app and I'm got it all pretty much done. The app gets the local weather by zip code which the user inputs into a textbox. What I would like to do is have the app check the submitted zip code against a list of valid zip codes. Now, I have the list of zip codes and there are honestly more than I thought(approx. 43,180). I tried to hard code a string array with the zip codes but that caused visual studio to get too sluggish to use. Does anyone have any ideas on how I could check the users zip against the list of zip codes, or could you point me in the right direction? Thanks for any and all help.
Oh yeah, I forgot to mention I'm using vb.net.

Database to hold the data and possibly a ComboBox or TextBox, using AutoComplete, depending on your requirements.
