how to use scroll bar in pictur box
Piyush Vardhan Singh

You'd have to write the code yourself to make the scrollbar have the right extent, and to move the image. IMO you're better off just drawing the image in your paint event, it makes scrolling easier to control.

good day everyone,
i hope you can again help me with this:
code :
dim strVal() as string
dim sVal as string = "a-b-c" - this can be changeable
dim result as string = ""
dim xCnt as integer
strVal = split(sVal, "-")
for xCnt = 0 to strVal -1
result & = strVal(xCnt)
next
first run : result = abc
second run: result = abcabc <<-- this is the problem
the code above runs smoothly, and no errors:
but for the second runtime of the code above it does not clear the previous "strVal" value / results.
how to clear the first result value of "strVal" ?
thank you in advance, your help are highly appreciated.
links/code are most highly appreciated thank you...
start a new beginning in every ending; thats what life for......

Start with result = string.Empty at the top of the loop.
You can't clear an array, it is a fixed size object.

Dear Friends,
I am trying to run an VB.NET 2003 project in 2005. After the successful conversion, If I run the project it is showing the below error.
"Visual studio cannot start debugging because the debug target "c:\.... project.exe" is missing. Please build the project and retry, or set the output path and Assembly name properties appropriately to point at the correct location for the target assembly"
Please help to avoid this error
Regards
Azeem

What you need is some code to read and write to a database - sorry but no one here is going to do all you work for you - buy a book. Amazon sell books - please dont let your next post be "Help needed using amzon to buy book".

If you were to spend a few mintues on google you would have found:
http://www.w3schools.com/sql/default.asp
and would have solved it in less than the time it has taken to wait for a reply.

Look I am not going to rise to the bait and start arguing. If you need to update a table you use the update SQL command with the columns you would like to update and the clause for which rows you would like to update (if not all).
I suggested you buy a book because if you are working on databases and struggle with the simple things (thats not a dig - every one starts somewhere) then it would be a wise idea to read up on the topic - that way you will be better equipped to make informed decisions about the best way to work with your tables and it will also benefit you in the long term.
As for nervous - I am not sure where you got that from - the only thing I am nervous about is that they let people like you near databases.

Your subject line said you had a "problem about Autonum", but you failed to describe what that problem was.
