My need is that i should be watching a particular location on the client machine which i can do it through FileSystemWatcher then without any user interventin it should transfer file from that location to the server.

I have to use a window service for that in which i can use either FTP or Bits or any other.

Can I use web service also?

I think that web service needs to be called through a web page. You cannot call a web service just by connecting to internet?

Correct me if I am wrong.

In this case, I would probably use BIS to do the transfer. It has a couple of advantages:
1. BITS transfers files in the background so foreground applications don't take a performance hit.
2. If other applications need more network bandwidth, BITS detects this and backs off on its use of the network.
3. If the user shuts down the machine, BITS will pickup the file transfers from where they left off. You don't need a continuous network connection to stay up for the entire file transfer.

I would not recommend using a web service to upload the file for just theses reasons. I would probably still use either FTP or HTTP server to upload the files to. When the transfer is completed (BITS does support notifications like this), then you could probably call a web service on that server to look at the file.

Just make sure you upload the file first, THEN notify the server that its there. What's the point in notifying the server of a file that you haven't uploaded yet?

Thanx, I have tried looking for some tutorial on BITS but haven't find which can help me in developing the project. If you can provide me the link of some tutorial which can assist me in application development.

Other thing is does BITS has an authentication mechanisim like FTP.

I have read on the Microsoft site that the message storage capacity of MSMQ is 1.6 gb and can be extended upto 3 gb. If this is true then using MSMQ for Distributed env is not suited.

Can you suggest some fail-safe messaging technology just like MSMQ but without the Storage capacity limitation

What on earth do you mean? What can you possibly be sending that's going to take up that much space?

Messaging is for sending application messages, not monsterous libaries of information!

I am not sending earth, But earth people would be sending millions of record every day which can vary from few kb's to 3-4 mb's. How much scalable you can make it that is the question?

Dave Kreskowiak8-Jul-05 12:04

Very scalable. And if your going to have that kind of traffic, you would be wise to have multiple MSMQ servers running to handle the load, especially if one goes down for any reason.

Thanx and we can check in bits the transfer status, it is in the BITS link you provided.

How to change a file content?

Why are you posting this across the site ? Why not go back to whereever this person helped you, and respond to them there, so they get an email notification ?

I want to open a text file and change some content.
For example, find a string 'aaa' and replace it with 'bbb'.
How to locate the 'aaa' and change?
Input,write command do not locate the file pointer.

Re: How to change a file content?

Christian Graus4-Jul-05 17:34

You can't. Not quite like that. You need to load the entire file, make your changes in memory, then copy the new file over the old one.

Printing TextBox Text

Anonymous4-Jul-05 10:20

Hi all,

Is there a easy way in .NET to print the contents of a TextBox? Or must you create a PrintDocument?

If a PrintDocument must be used, how do you handle lines that are longer than the page width? Is there a way to find out the maximum number of characters allowed on a line in a PrintDocument?

Any help would be much appreciated. Thanks!

Thanks for the link.

I have been there prior to posting here and have tested their sample, but this does not handle word wrap properly.

Any other suggestions?

Anonymous5-Jul-05 15:43

<br />
Dim f as System.IO.StreamWriter = New System.IO.StreamWriter("C:\file.txt")<br />
f.Write(TextBox.Text)<br />
f.Close()<br />
Shell("Notepad.exe /p C:\file.txt", AppWinStyle.NormalFocus)<br />
System.IO.File.Delete("C:\file.txt")<br />

Not the most elegant way, but it works for me.

how to do VB6 and serial ports abow COM16

6-Jul-05 4:35

I was actually thinking of doing something like this, Thanks. Smile | :)

But is there some command-line arugment to allow the print dialog to show up? I know that the user may not use their default printer, so a print dialog would be really useful.

Any ideas?

Im now using mscomm in a VB6 project but as I understand this component does not support ports abow com16. If USB BT, IR and serial dongles is used ports easily starts getting numbers abow 16.

What is the fix or solution to this problem?

If there is no solutions for mscomm suggestions to other components with a word about own experience would be great, comersial or free.

In VB6, there isn't a fix. You'll have to find a COM-based SerialPort control that supports this. I don't know of any.

Nothing, but he DOES have a link to a Russian casino type site, from the look of it. Hence my comment.
