I don't get Channel's (TCPChannel, HTTPChannel), is it just a new way of doing Client Server Applications????
Could some one shead some light on this for me... thanks
|
|

TcpChannel and HttpChannel are used for .NET framework's Remoting part. Remoting can be said to be one way of building client server apps, yes. Basically it's a mechanism for client and server to communicate. And they communicate through the channels (tcp or http) with messages passing through various sinks that can be used to encrypt/decrypt or processed in some other way.

I have Master-Detail datagrid. The detail datagrid is embedded in the Master datagrid. In the detail datagrid I want to implement paging ,sorting etc. I have addes the event handlers delegates manually. For some reason the pageindexchanged or sort events for the detail datagrid. Does anyone know of this behaviour? I saw a lot Master-Details datagrids on the internet, nobody seems to have implemented paging-sorting for details grid embedded within a datagrid. thanks

Hello everybody,
Perhaps someone has experienced the same problem as I had:
I have developped an application and this application is a bit complexe to configure: several DBs, some parameters that depends on the system (such as log files path) and so on. These configuration item are stored in the .config file.
Now, I want to distribute my application. So I built a setup project for it. My problem is that the msi file contains my .config parameters which will not work on an other system. The simple solution is to edit manually the config file after install, which is not very convenient.
I was wondering if there is a way to automaticaly add screens in the setup wizard to configure the application and write the config file while installing.
tahnks in advance.

I don't think the setup stuff that comes with VS.NET can do this directly. You would have to create some custom actions which would then do the work of editing the .config file.
Some time last year I tried to create a custom action, but eventually gave up on it. I can't remember what I was trying to do though.

I have .NET 1.0 (v1.0.3705) and .NET 1.1 (v1.1.4322), but my programs use .NET 1.0. I noticed the presence of the FrameworkVersion=v1.0.3705 environment variable on VS.NET command prompt, which I don't know how to change.
How do you make your programs use the .NET 1.1 version?
|
|
|
|
|
Your programs should automatically use the 1.1 version when it is available (unless you specify otherwise in a .config file). But you probably want to compile with 1.1 so you can use the new features as well 
When you installed the SDK, a batch file was installed that sets up the environment variables. On my computer this is at: C:\Program Files\Microsoft.NET\SDK\v1.1\Bin\sdkvars.bat. If you point a shortcut to: %comspec% /k C:\Program Files\Microsoft.NET\SDK\v1.1\Bin\sdkvars.bat then when you open that shortcut you can compile with .NET 1.1.
VS.NET 2002 cannot target 1.1, it was hard coded to target 1.0; so unless someone "patches" it you are stuck with 1.0 for builds through it.

How do you know your apps are using .NET Framework v1.0 and not v1.1?
There is one test I know for sure; With ADO.NET try to use the RowCount</count> property of a <code>SqlDataReader If that works then you are using 1.1 because it is not available in 1.0.
Also that VS.NET cmd prmpt env var: Do you have VS.NET 2003 installed? If not then you have 2002 installed and it will be setup with v1.0.3705 . Once you install 2003 then normally the cmd prmpt in the 2003 folder will be v1.1.

Have you tested this out at all yet performance wise? Just curious because I have not installed 1.1 yet. I wonder who much this effects the performance of the datareader.

I'm currently working on a Softwareproject where it must be possible that two applications could talk togeter (with RPC's and only local). My Project bases on the .NET Framework and I'm new to it (without the .NET Framework i would it implement with COM).
I read on a few Articles that Remoting is the "COM" in the .NET Framework. But theres one thing that bothers me: When I'd like to use Remoting only local, why must I allways declare a port? 
Can I use Remoting without a port or is there any other possibility for implementing RPC's?
Thanks for any help in advance!
And sorry for my bad english... 
Regards Stefan

I downloaded and installed the .NET Framework 1.1. I then downloaded the .NET Framework SDK 1.1 and installed. I then downloaded the SharpDevelop IDE and proceeded to use that.
I tried to create a C# Service. When I tried to compile the template C# Service it creates it informed me that the namespace "Installer" could not be found. I looked this up in the SDK documentation and it said that it was part of System.Configuration.Installer
Everything I read says this is where it is. I can't find this anywhere on my system. It wasn't installed. Does it get installed with something else other than the .NET Framework SDK?
Help please.

OK, I created a new service, compiled it, and it gave the same error. Added this code to the top (w/ the other "using" statements):
using System.Configuration.Install;
Then it compiled correctly.
This declare should be in the template file, but it's not. I shall mention this to the #D team.

That did it. Thanks. Just starting to use .NET and C# finally!  I'll keep in mind that the IDE is a little rough when it comes to certain things and try to learn to type.

Okay the help file says it exists, and the Class Library Referance says it exists, but intellsense can't find it and it creates a compiler error . What am I doing wrong? did I miss a posting and fall off of the bus?

You need to reference the DLL...
In Solution Explorer, Right Click in references and click Add reference.
Add the System.Design.Dll

Righto!
Why is all of the obvious stuff that eludes me?

If I create a stored procedure that uses a temporary table, I cannot get a .NET data adapter to configure correctly for that stored procedure. A workaround is to create a stored procedure with the same data columns, generate a data adapter and dataset, then change the stored procedure called by the data adapter. Is there a better solution to this problem?
Thanx...

I wrote a service that use VB6 MSCOMM32.OCX for serial communication.
I works perfectly on my development machine which has both .NET studio and VB6 installed. But when I bring it over to a computer w/o VB6 installed it doesn't work (i registered MSCOMM32.OCX).
I got the following error: System.InteropService.COMException from the service. The odd thing is that the service monitor tool which is a winform application, which also use MSCOMM32.OCX but has a wrapper class that generated by winform, works perfectly as well.
the Error when I debug it says: Class is not licensed to use
Please help.
Thanks

What was the COM exception?
|
|
|
|
|
The exception was thrown was System.InteropService.COMException, the error message was : class is not licensed for use.
Other than that, it doesn't have any other error. Please note that it works fine on the machine that has both .NET Studio and VB6 installed...but not others.

Is it the lciense file for the OCX. I think the corresponding OCA has something to do with this but what do I know...
|
|
|
|
|
I copied the OCA file with it as well...but nothing works. as I mention, this is odd since the winform version works fine, but the service one doesn't.
|
|
|
|
|
We are having the same problem and have talked with MS. It seems like MSCOMM32.OCX requires some kind of certificate before it can be used, and that certificate is installed when you install VB6.
Our way around it is this:

Hope this helps,
