can anyone help explain what might happen to a .NET application if file system crash? Simply put, should the apps pop up warning/error reminding that file system is carshed? How does your apps deal with file system crash?
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.

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.
I do I get description from Public Enum?
Public Enum API
''' Using Google API
<description("google api")=""> Google
''' Using Yahoo API
<description("yahoo api")=""> Yahoo
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 AsNew Process
Dim StartInfo AsNew System.Diagnostics.ProcessStartInfo
PublicSub Audio128(ByVal MyPathandFilename AsString, ByVal MyFileName AsString)
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
