The code looks right, but will NOT work in an ASP.NET page. VB.NET code runs server-side and will launch this calculator on the server, NOT the client side. The calculator will also NOT show on the servers desktop because it's being launched from a Service.

Hi,
I used to be able to set DirectoryInfo to a path greater than 256 characters in VS2003 by using the GetShortPathName functuon but since I updated my code in VS2005 DirectoryInfo sees the path as the full length not the short path. It throws a PathTooLongException.
Does anyone know how I can get around this?
Example:
'ReallyLongPath is over 300 charactes long.
Dim ReallyLongPath as string = "D:\LongFolder\LogSubFolder\etc..."
Dim di As DirectoryInfo = New DirectoryInfo(GetShortPathName(ReallyLongPath))

That trick isn't going to work. One of the first things the constructor for the DirectoryInfo object does, in .NET 2.0, is convert the path you give it to a normalized form. That means converting it to it's Full Path specification. The limit on that returned (internally used) path is 260 characters.
No matter what, it's NEVER a good idea to use paths that long, for any reason. Not because of compatibility issues with the .NET Framework, but because of the same issues with other software, like BackupExec. Keep your paths under 260 characters if you want to avoid future problems.

I understand the reasons for keeping the paths to a decent lenth but I currently have a machine that has paths that go much deeper than 260 characters and the shortpath trick used to work fine with the drirectoryinfo object in .Net 1.x. Is there no way around this in .Net 2.0?
Thanks.

Nope. Like I said, the first thing the DirectoryInfo object does is normalize the path to its full length, so you can't use it for what you're doing.
You can try to use the the static methods (Directory class, not DirectoryInfo) and try to use the return path from GetShortPathName as the directory to search. But, I'm seeing code in there that looks like it might also normalize the path too, though it might not.

You'll have to ask this in the ASP.NET or Web Development Forums. THis will require client-side JavaScript. You can't do it using VB.NET on the server-side.

hi,
i have added a button in windows datagrid. it works fine when i load the grid first time and click the button. but if i reload the datagrid again on some event and i click the button, its click handler is called twice.
if i again load the grid then the click handler is called thrice.
how can i correct this ?
i want to call the button's click handler only once like in normal application.

Somewhere in your code you used AddHandler to wire up the Click events of the button. Before you reload the data into the grid, use RemoveHandler to unwire those buttons before you destroy them.

or you can use module level boolean variable to check wether the button is already clicked

I have an array of objects. Each object refers to an mp3 file as follows:
mp3file.Title
mp3file.Artst
mp3file.Album
mp3file.TrackNumber
My question is, how can I sort the array by a specific item of the object, eg. Sorted by Artist, sorted by Album etc.

Make a custom comparer for your class, and use that in a call to Array.Sort.

It's amazing to see how much work some people will go through just to avoid a little bit of work.

Thanks for the quick reply.
You say, 'Make a custom comparer for the class'. I'm fairly new to VB.net and don't quite understand what you mean. Please could you explain a little more.
Thanks again
