Hi All,
I am using FileSystemWatcher for checking the files in drive("C:\"). and add those files who are adding in "c:\"Drive to copy in "D:\".
It's working normally but when i try to copy file which size is large. then the error is generated file not found.
So How to check file is in progress of Coping.
Thanks
If you can think then I Can.

What's the error message?

File system wather shows that the file is added and at that time i try to start copy of that file.
Then following error message is displayed while the file is large.
The process cannot access the file 'E:\test.dat' because it is being used by another process.
If you can think then I Can.

You are getting the error because the file is still open/being written too, therefore your program cannot gain access.
What you need to do is keep checking the state of the file until it has been released and the perform whatever tasks you need for example :-
Dim OK As Boolean
Do
Try
'Open file and perform tasks here
OK = True
Catch
OK = False
End Try
Until OK

Thanks for reply,
I have already using it.But it creates problem while File Can't Copy or Cancelation of Copy.
Because Do While Loop Not Found status of File.
If you can think then I Can.

You have to make the loop try to open the file for exclusive read. If not, you sleep for a couple of seconds, then do it again. When you get the file opened, close it. Then you should be able to use the File.Copy method to copy your file.
The FileSystemWatcher told you that a new filename appeared in the directory, not that the file was completely written.

OK. Where are you uploading to ? Is this a web app ? What is the issue ?

What is your connection string ? If the DB will be local, use localhost, not the machine name.

Check your Database field which you R Trying to insert null value is not a required filed in that table, and it's not a *NOT NULL* Field.

Don't think Access'97 supports null strings.

VB6 and Access 97? Why are you developing in dead software/languages?

If the field is able to store NULL values, then you should also use the NULL in your insert statement:
insert into table (field, field, ...) values ('value', null, ...
|
|
|
|
|
In the design of the Access database table in question, ensure that the field is set to 'Allow Zero Length' and that it is not 'Required'.

Hello There,
I am developing a POS Application in vb.net and using Firebird 2.01 as Database. the only problem i have there is when the connections to Firebird increase...The Client Software starts FREEZING...mostly when updating a table [Stock]. Can anybody help.

Sounds like the software is freezing because of issues with the DB. Perhaps if you do your updates on another thread, or get a better database ?
