I did a Google on that problem and I only found a few references, if it was fixed by a service pack or whatever I've not found anything about it. But, like I said, I haven't seen mine do it.
I do have server 2003 all up-to-date.
here's a reference to that problem:

I didn't say the extension had to be installed on the client.
You really don't have a choice here. The FileSystemWatcher class only triggers events well after they have occured, not during the occurance. It also gets slower and slower at triggering events the bigger the directory tree you want to it monitor. Try having it monitor your entire C: drive and watch what happens...
Now, you CAN put a stub in place of the file, but when the client double clicks the file, it's the CLIENT that runs the stub code, not the server. Since the client knows nothing of the tape backup system and will most likely NOT have rights to it at all, you've got a huge problem. This is only solvable by code running on the server and the only time this code will get executed is when the file system get an Open request and follows the installed chain of extensions.

I found an article that talked about HSM reparse point. It deletes the content of a file and creates a reparse point(stub) in it's place. When the application opens the stub it does not know any different. Are you familiar with this and how to create it in code?

Reparse Points[^]
Yes, I'm familiar with the concepts. No, I haven't written any code for it.
What you're looking for is the Windows Installable File System (IFS) Kit. It has everything needed to write a reparse point filter driver for NTFS. Since your writing a kernel mode driver, you really can't use VB.NET or any of the managed languages to do it. It is HIGHLY (can't stress this enough!) recommended to use C++ to write this...

You can get the data from an image, just specify the format. Then you can encrypt that, if you like.

Singapore? What are you doing in Singapore?
Vacation? Please tell me you're not on CodeProject in the middle of a vacation?

There are examples of using Regular Expressions all over the 'net for validating the format of an email address. An example of which you can find here[^] on CodeProject.

Hi to all.
Please help me. I have to connect an autorefractor machine with my medical software so that the readings directly comes into my software and get stored in my database. i donot know where to start can anybody give me a hint. my platform is visual basic 6. and mysql .
any help will be highly appreciated.
thanks

I may be able to give you a hand.
Normally, the data is aquired thru the PC's serial port to the autorefractor own PC software.
You'll need to specify the brand and model of the autorefractor and if or what software you have for it, And I'll see what I can dig up about it.

Thanks very much for replying me. I want to know that the interface will be provided by the brand or i have to code it. should i ask about it to some of the vendors . will they know anything about it.
|
|
|
|
|
I would amagine that if they are good vendors, not just salesmen, that they would know.
Otherwise, I would get the Information on the specific model right from the manafacturer.
decoding serial data is not hard if you know the format of the data.
but if they provide the software interface you may just need to import it into your software.

Have you tried the Manufacturer?, by the way what brand and model is it, maybe I can help find it...

These are the brands Humphrey,goldman,Zeiss, .Thanks a lot for helping me so much. i think i can atleast see the way to go as i was totaly in dark before this.
thanks

aparently Zeiss and Humphrey are the same company
here is a link to the software for them:
http://168.143.167.66/humphrey/HFA12_5Letter.html
I'll search around and see what else I can find

woop's the other link may be wrong, it's for the field one... here is the link to the autorefractor you must register apparently..
http://168.143.167.66/

Looks like goldman only makes the lenses,
I would download their software and check it out, see how it stores the data and go from there.
Let me know if you need some more help.

Hi,
not sure if the subject is really clear but anyway, what I am trying to do is to create a generic data adapter for the different datasets I am using, I don't like all the code .net crestes to add the parameters to the data adapter. In order to do this I read the necessary columns from the tables in the datasets as I or .net defined them on design time. In my procedures I change the columns of my datatables, so in order to creaste the update command parameters I need to get back to the original dataset. As I don't know how to get the original settings out of the current dataset I decided to Dim a new dataset, just for the sstructure, which is the same Type as the current dataset. This works OK if I know at design time what kind of dataset I need to expect, but then durign development you need to go back and update some kind of Select case statement every time you add a new dataset to your project. I have been trying with Ctype and gettype statements but I do not succeed. Guess it is straight forward and I am just missing at least one thing.
Any suggestions?
Public Sub dsAction(ByVal dsOrig As DataSet)
' Dim Audit1 As clAudit
Dim strSQL As String
Dim tb As DataTable
Dim cl As DataColumn
Dim intCount As Integer
Dim strSQLUpd As String
Dim strSQLUpdWhere As String
Dim strSQLIns As String
Dim strSQLInsVal As String
'Dim strSQLDel As String
Dim Newdataset As New dataset
Dim ts As Type
'Audit1 = New clAudit
!! THIS line does not work
dataset = CType(Newdataset,gettype(dsorig.gettype.fullname))
Try
'Open the connection.
'Me.OleGenCon.Open()
For Each tb In Newdataset.Tables
Dim OleDaA As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter
Dim OleDUpdA As OleDb.OleDbCommand = New OleDb.OleDbCommand
Dim OleDInsA As OleDb.OleDbCommand = New OleDb.OleDbCommand
strSQLIns = "INSERT INTO " & tb.TableName & "("
strSQLUpd = "UPDATE " & tb.TableName & " SET "
'strSQLDel = "DELETE FROM " & tb.TableName & " WHERE (GEN_ID = ?)"
For Each cl In tb.Columns
OleDaA.TableMappings(0).ColumnMappings.Add(cl.ColumnName, cl.ColumnName)
If Not cl.ColumnName = "TABLE_ID" Then
If intCount > 0 Then
strSQLIns = strSQLIns & ", "
strSQLUpd = strSQLUpd & ", "
End If
Think, try, think, think, try, think, think, think, try, ASK, think, try, advance on step and start over...
