ClickOnce or your install program are the best way to do this. Otherwise, you need a patcher program that runs and overwrites your exe.

sorry, Sir what is clickonce?
|
|
|
|

The best way is publichingg your application with clickonce.
After completing development your application right click on your Windows application and select publish.
After that all you have to do is put published files to a location such as web site, ftp or file share that users may access.
To install users may open publish.htm and click install or double click the .application file at the root.

what does it mean by clickonce? Is this a software?

Sir,
How about this scenario, i have one main big application under that i have application service, web services and plugins that are all .exe and installed in client server. If i have update on my domain server for one of my .EXE file, does the main app need to be updated also o can i just update the .EXE file.

My app has a number of projects in it. They all use the same namespace (ClientServerTimesheet).
I need to print some grids, so I have added Printing.DataGridViewPrintProvider to the solution, without changing its namespace.
In the client part I have added a reference to it and I can print. But I have a problem with the height of the first row and so I want to look at the array of row heights.
I have a project Globals, with a class Lookup. Lookup contains a public static array of float rowHeights.
In DataGridViewPrintProvider I have added a reference to Globals.
In DataGridViewPrintProvider I use the line
global::ClientServerTimesheet.Lookup.rowHeights[row.Index] = GridView.Rows[row.Index].RowHeight(g);
but it won't build, saying that Globals does not have a strong name.
I supect that what I actually need is to qualify the above line better, or do I really need to create a strong name for Globals? Not sure how to do that with C# 2008 Express

What Exception are you getting?
Nothing you've said would seem to indicate a problem.
I've never found a need for global:: and I don't think it's required here. Are you somehow confusing it with your Globals project?

I just put the global in to see if it helped.
No exception - compile error: Assembly generation failed -- Referenced assembly 'Globals' does not have a strong name : Printing.DataGridViewPrint
But Code Completion worked when entering the line. And other places in my code I can access variables and constants in Lookup (although I don't need the ClientServerTimesheet. as they are in the same namespace.)
I renamed he project that contains Lookup to SolutionGlobals as well as its Assembly Name and the compile error follows the change.!!
If I comment out the line code compiles and runs.
I checked the Build Order and Dependencies. Printer.DataGrisViewPrintProvider is only dependant on SolutionGlobals (Lookup) which is compiled first, and only the client is dependant on it, and client is compiled later in the order.

Hmmm, well there are situations where an assembly needs a strong name. And as I recall, a strong-named assembly must refer to only strong-named assemblies. So, basically, if any of your assemblies will be strong-named they all must be. I use one strong name file thingy for all the projects in my solutions and that takes care of it.

After giving all 17 projects a strong name it now compiles!!

Hi Friend,

Are you using outlook InterOp services. If so, the API will be different in outlook2003 and outlook2007.

The error means what it says. Your column is of the text type, not nvarchar.

In Microsoft SQL Server (and probably any other RDBMS that supports transactions), TRANSACTION is a reserved keyword.
Change your SQL to read
INSERT INTO TransactionType([Transaction],Description,Category,Active)
VALUES(@Transaction,@Description,@Category,@Active) The square brackets indicate a name rather than a keyword.

THANK U VERY MUCH ITS WORKS

The error is telling you that you have a problem with your SQL being sent to the database, not with your C# code.
Transaction is a reserved word. Try surrounding it with square brackets [Transaction]

I have a telnet server that runs scripts. I have a command called
files_download "path\filename.zip"
All this does is send a file from the telnet server to the terminal program. I'm trying to use fdsz and gsz File Transfer protocols to send these files. When I run it. The fdsz or gsz starts. I keep getting port not detected. Well I even tried fdsz port 23 sz %1 and I still get the same error
Can some one tell me what I'm doing wrong and how to fix this.
Thanks
Joe
