Why not use a MaskedTextBox?
|

You can set up an event handler for keypress event to check whether the key that was pressed is digit or not. Depending on that you can ignore the key if it isn't a digit or a backspace

Showing dynamic images in crystal reports would be a hectic problem. Passing image name and showing it over there is not possible. One option would be storing image in database as BLOB. Crystal reports having capability to render this BLOB data. But for this you need to switch your DB to SQL Server.

My application will generate a word document as report. The application created Word Application and Document objects.
When users click on Close or the "X" icon on the up right corner. The application will intercept word DocumentBeforeCloseEvent, to ask users Save, No or Cancel to the document changes. Everything works fine except when users click on "Cancel", Word still displays it's own Dialog for users to select Yes, No or Cancel for saving the document changes.
Is there anyway to prevent this Word dialog because my application already process uses decision?
Here is part of the code:
Word_DocumentBeforeClose is used to process users decision.
The last part of If in else is to process when Cancel is clicked.

Hey,
I'm having some problems starting a command-line program using Process.Start(). I pass it the filename and arguments, and it runs the program, but instantly crashes and a "Program has stopped working" error comes up. I can't figure out what is wrong. The program runs fine from the command line and when I use a shortcut, and Process.Start() runs other programs fine. Can anyone tell me what is wrong?
For reference, I am running this in Vista.

As per my experience you have problem in passing arguments.
Try without argument passing, and change the way to pass arguments.
Hope you will find solution.
I have tried to give hint to your problem.

Well classical problems like this are solved by using unmanaged code equivilant to the System.Diagnostics namespace from the win32 api.

I inherited a program that takes data from a csv file and inserts it into a database.
The data is in the following format:
8/20/2007 12:14:21 PM,HDFM,"Nick Yockell","Nate Wittrock",239-850-3931,239-850-2514,"Used 2004 Harley Davidson ","bought bike
CUSTOMER WANTS TO BRING HIS YAMAHA R6 IN TO TRADE AND SEE HOW MUCH PAYMENTS WOULD BE.
",Deliver,aa32ed31-f0c8-4f43-a7d4-830d9f29edcd
For some reason the function that saves the data to the database is having a problem with the customer phone number (5th column).
The database column is a varchar(50) - the same as the customer business phone number.
If the customer home phone contains anything other that digits it cannot be saved to the database.
However, the customer business phone can contain anything and gets saved just fine.
Is there anything in the two functions that could be causing this ?

Shouldn't you then have the phone numbers wrapped around quotations as well? Seems like most of your other fields are.

Is it possible to get sound data from the microphone? Everyone keeps telling me to go for SAPI, but I'm not doing speech recognition. I'm looking for a way to get data like the sound data in a .WAV file. I need to get the sound, like the Sound Recorder program that comes with Windows. Any suggestions?

You have to save the source control name when you are showing the context menu in variable and use that value to proceed the context menu command.
