for example, a designated folder got changed, not able to write into it, the system shall pop up error message, right? so I have to make specific error exception/message for this kind of case, otherwise the system just gave general error message, am I right?
As the inability to save to a certain location is a predictable exception (e.g. the user attempts to save into the Windows folder on Windows 7 when running with normal permissions), it's always a good idea to protect against this type of exception.

can anyone help explain what might happen to a .NET application if file system
In general - no.
How does your apps deal with file system crash?
Whatever the business requirements suggest and reasonable extrapolation from that.
For example I don't try to do anything at all about the file system filling up for a server. Can it happen? Yes. If it does what can I do? Nothing. I do however expect that any reasonable operations setup would take into account file system monitoring.
As another example if I can't read a configuration file that the server requires on start up then besides logging an error I can do one of the following
- Start with default values.
- Exit the server.
The choice depends on what was supposed to be in the configuration file that I was reading.
(Note that a logging solution MUST be implemented such that a logging failure does not stop the application from running.)
A stand alone user application should probably do something different. If it cannot read/write to the fle system then it should report that to the user.
Just a guess: The backslash/left-angle-bracket combination may be confusing the parser. The backslash character is sometimes used to "escape" the following character. If this is happening, it may not be recognizing the left-angle bracket or the end tag.
Dim myprocess As New Process
Dim StartInfo As New System.Diagnostics.ProcessStartInfo
Public Sub Audio128(ByVal MyPathandFilename As String, ByVal MyFileName As String)
StartInfo.FileName = MyProgram.exe
StartInfo.RedirectStandardInput = True
StartInfo.RedirectStandardOutput = True
StartInfo.UseShellExecute = False 'required to redirect
myprocess.StartInfo = StartInfo
The script works fine but the prompt is displayed while the program EXE works.
Is possible to hide it?
Thanks in advance
In my asp.net dynamic data project I want toread an excel file using suitable Microsoft technology (Not Excel). Someone said their was a server side tool for this? I want toread the first few columns of data from a table?
Any suggestions or directions onwhereto go?
It depends on the version of Excel format the file is saved in. If it's in 2003 and below, it's a multiple stream binary file that will be just about impossible to decipher. If it's 2007 and above, it'll be a .ZIP format file with multiple XML files inside of it. Again, a royal pain to decipher without the SDK. Seriously, save yourself MONTHS of work and use the Visual Studio Tools for Office to do this.
I neglected to include my DB creation script in my Git repo to bring it home for some weekend get-ahead work. Now I thought the lauded 'Generate Database from Model' feature would be my saviour here, but it's useless. It uses the entity set names to generate table names, so where all my original table names were singular, the generated ones are plural.
Some wag at StackOverflow suggested making all the entity set names singular but all I can think of is somehow extracting all original table names, generating the script, then doing a marathon search and replace. Any suggestions on how I could do this? Any other suggestions?
Disclaimer: This is a duplicate of my StackOverflow question here.
