The way to do this that isn't insane, is to dynamically load the dll locally and jsut write code that checks the server for a new version and installs it if it exists.

If I understood right, I should write a small application that running on each one of the local computers and check for new version of dll and if there are new version of dll I have to copy them to the local client pc?

If yes, this is a big project because we have a lot of application and a lot of dll and a lot of computers in our factory.

I thought that instead of using the dll from Local pc, the program will use the dll from its location on the net. And after upgrading it, the program will use thi last upgrade one. Can it be done in this way?

No, you can't. Apart from any other considerations, you want one PC to run all the code for all the computers in your factory ?

It's really not much work at all. It's boilerplate code, you write it once and reuse. Hell, just deploy with clickonce and set it for automatic updates.

Thank you all for your fast replies.

How can I set a program for automatic updates? Do you mean from windows schedule?

Only if you wrote both programs. WM_COPYDATA is one way to do it.

If they are both .NET programs, you can probably decompile the program, change it and recompile. Otherwise, you probably can't do it at all.

Good Morning All

I have been Building my applications in Tiers and they are working well. i have a Question. the 3 Tier Applications after Compilation will be DLLs now, in my Case when ever i install the Application in my Clients Computer,, my DLL's (Layers). So all the DLL's are in the Same machine and my Users are not many so that doesnt accect the Perfomance of my Application. So i would like to how can i take one Layer and take it to another Server and and another Layer(DLL) to another server, so that when the number of users Grow the perfomance will still be good, and how will the other layer know the location of the other layer if they are separated, is that achieved through code and how.

Thanks

You would do this by writing code to communicate between layers over the network. Odds are, the speed of network traffic will negate any benefits you may hope for.

Hi: Does anyone know, or have code, to color the Windows XP taskbar Confused | :confused:

. I know some of the Windows Blinds software does this; but, then both I and the end user would need the software installed.

I sometimes make themes and would like to coordinate the taskbar color with the wallpaper Wink | ;)

.

And a small program just to do this (and have it reversable by running a second time would be what I want).

If I knew where this item was in Windows I have someone who might be able to help.

thanks, Harry Dead | X|

You do this with WMI. The processor Id is a better candidate IMO.

Hi all,

I wanted to write an application, that could scan a receipt and read the items bought. Each item is in a list and can be edited before saved. The line on the receipt right before what items that were bought will have "Items Bought". I heard that I may have to use OCR to recognize the items. Can anyone help? If I need to buy a third party OCR, then please recommend one not so expensive with a great success rate.

You 'may' have to use OCR ? There's really no other way to do it. I'd recommend the Atalasoft libraries, they have OCR, and all the libraries I have used of theirs have been great.

Hi there
i'm making a very simple downloader in vb.net to download images from a certain server.
just by entering the url of the html file, download location of the images are obtained through some regEx. (and some user inputs)

there are couple of image sizes named accordingly. some images don't have bigger sizes though.
if small image = image001s.jpg
if large image = image001l.jpg
if gigantic image = image001g.jpg
and so on.

the problem is I don't want to have to download the html file to see if a link to bigger size exists.
I just want to check if it exists on the server and if possible i'd like to get the size of the file.
so i just would like my program to return and error or do nothing if bigger sized image doesn't exists.

for example:
I open up example page: http://www.mywebsite.com/2008/03/12/article555.htm
I can see that there are 10 image thumbnails in the htm page named:

http://images.mywebsite.com/2008/03/12/555/image001s.jpg
http://images.mywebsite.com/2008/03/12/555/image001l.jpg

http://images.mywebsite.com/2008/03/12/555/image002s.jpg

http://images.mywebsite.com/2008/03/12/555/image003s.jpg
http://images.mywebsite.com/2008/03/12/555/image003l.jpg
http://images.mywebsite.com/2008/03/12/555/image003g.jpg

so image 1 only has small & large, image 2 only small, and image 3 all sizes.

I want to download the biggest images..
any help?

Hello, I am new to VB.Net and require some help?
I am trying to write a program which reads various text files (depending on if a tick box is checked)and combines them in a ComboBox. However I would also like to be able to set the colour from each of the text files? How do I do this?
This is the code I am using to read and combine the text in a comboBox

Dim QNLDef As New System.IO.StreamReader("C:\QNL\QNLDef.txt")
Do Until QNLDef.EndOfStream
Me.ComboBox1.Items.Add(QNLDef.ReadLine)
Loop
QNLDef.Close()

Dim BradyList As New System.IO.StreamReader("C:\QNL\QNLBrady.txt")
Do Until BradyList.EndOfStream
Me.ComboBox1.Items.Add(BradyList.ReadLine)
Loop
BradyList.Close()

Any help would be appreciated.
Thanks, James.
