Yes I had the class on both sides, but I've done some reading on msdn and found that serializing an object records the assembly name to deserialize it again, which is why I was having the error, since it was going from Server to Client assemblies, so I've put the request/response objects in a shared .dll file to resolve the problem. seems to work fine 
Thanks for replying

Is there any way to use a class from a dll? or do i have to use a StructLayout?
|

On C#, AFAIK, it would be too much trouble. The easiest way would be using Managed C++ and writing a simple wrapper __gc class, which would be easily callable from C# and can natively call your dll. You can find some samples for that on the Web.
You can do it on anything you choose - from .bat to .net - A customer

could you give me a little more direction on where exactly to find a decent example?

I'm looking for a simple way to lauch Windows Explorer from C# and have it open up to a given folder. What I DONT want is to have a black command prompt window to flash up on the screen briefly while it executes a command line (I really hate that, and it confuses users).
I've looked through some WMI articles, but they seem overly complex for what I'm trying to do. Any suggestions?

hi,
anyone can give me some tutorials about the deployment tools in Visual Studio .NET?
i seems able to do more than my current understanding.
would anyone give me some help on that?
thanks,
jim

Don't worry, you are not alone. While there are some tutorials on MSDN, and VS.NET is a damn good environment, the VS.NET deployment tools suck (they are confuse, unstable and unreliable), that's why you are lost. I'm yet to find a good deployment solution for .NET.

Hi,
I recently had to build a installation program to install my application and I tried to do it using the "Deployment" project in Visual Studio.Net. After much research and help from the folks on this message board I was able to build the installation package.
There are 2 things to be done:
1. Create a new project of type "Deployment" and add all the components of your application to this project. You can specify the folders they need to be on the target computer, the icons/shortcuts on the desktop, the item in the Start->Program Menu, etc.
On building this project it will generate a .wsi file, a setup.exe along with other files. All the files generated in the Debug directory constitute the installation package.
The above package will run perfectly on any computer as long as it has .NET framework installed on it. If not then you have do the second thing.
2. Download the BootStrapper sample from the following link:
http://www.microsoft.com/downloads/details.aspx?FamilyId=BF253CFD-1EFC-4FC5-BA7E-6A6F21403495&displaylang=en
Its in unmanaged C++. Build it and it will generate a setup.exe. It also has a settings.ini file.
Copy the setup.exe and settings.ini into a folder, say, myfolder. Then copy the .wsi generated in step 1 above into myfolder. Then copy the dotnetfx.exe (the .net framework installer) into myfolder.
The dotnetfx.exe can be downloaded from here:
http://www.microsoft.com/downloads/details.aspx?FamilyId=D7158DEE-A83F-4E21-B05A-009D06457787&displaylang=en
All files in myfolder now constitute your new installation package. This installation will first check if .NET is installed or not on the target computer, if not, then it will silently install it and then it will install your application.
I hope this helps.

oh! really thanks! i have tried what you said... but, i need to do a bit more such as install mysql, startup mysql service... i am thinking to make a executable to do this and use a batch file to run it.
let me make such a "not so elegrant solution" first and see if my boss accept. otherwise, ask him to buy a deployment tools.
indeed, i don't know why detecting framework existance is so important but not included in the deployment tools.

Could you give us a small piece of code of what you are trying to do?

Hi,
I can't seem to locate a message box function for Web Based C#. Does anyone know how to do this, or have a Message Box control that I can add to my toolbox?
Thanks,
Glenn

There are no server controls for messageboxes in Web Apps. The closest you can do is use the alert() javascript in the client-side scripting

I have about 40 different dialogs that I would like to convert to a Form, because they are easier to work with and I don't have to write Win32 code to support them.
Does anyone know how to convert dialog boxes to C# Forms?
Thanks,

I have a fairly large application that I want to add a web interface to. The application is designed as a two layer application. The user interface and the so called API, which does all the work.
I would like to be able to call the API which is written in pure C with no operating system dependencies except for telecommunications.
I have tried to add a reference in VS.NET to the API's .DLL but it doesn't allow me to.
Is there an easy way to do this with out converting the entire application to C#? For fun, I tried to compile it using VS.NET 1.1 as a C++ application and the 1st program out of about 200 gave me 100+ errors.
Converting it to compile under VS.NET C++ I thought would be easy, but would take too long. Anyone have any ideas??
Oh BTW, my compiler that I'm currently using for my C development is Watcom 10.6B. I know its old and unsupported but I understand it. I'm trying to learn VS.NET...
Thanks,
Glenn

You could try using P/Invoke, which would involve some [DllImport] usage. P/Invoke[^]

So, ehr...
..hope you won't think that this question is in the wrong forum, but..
You remember all the good'ol'SQL APIs like SQLConnect, SQLFetch, ... ?
How can I access those from a C# app?
I've tried to use the System.Data.SqlClient namespace stuff,
but that is targetted for SQL Server DBs,
and I am just trying to do something more ODBC-oriented (i.e. that would
work with other DBMS as well).
To be specific: I really, really, **really** need to
execute an SQL<foo> call (rather than using Data Sets, and such).
Is it possible in C#, or should I just go back to C++ ?
Suggestions anyone?
Thanks in advance,
F.O.R.

1. System.Data.OleDbClient
2. SqlConnection,SqlCommand and OleDbConnection,OleDbCommand can execute SQL statements. You can use an OleDbDataReader (SQlDataReader if MSSQL) to retun records in a fast forwar-only cursor and do as you wish with the data. xxxCommand and xxxConnection can also execute quries that have no return data or onlay a single scalar value.

Thanks Rob,
but that's not exactly what I was looking for.
I suspect I'll end up moving to C++ one way or the other
Thanks again,

Look at the System.Data.Odbc (only in 1.1) and System.Data.OleDb namespaces for setting up connections and executing commands etc.
The OdbcCommand and OleDbCommand objects both have the ExecuteNonQuery method (and more) to execute SQL statements without involving DataSet and DataTable objects...
|
|
|
|
|
Hmmm...
..I didn't know that 1.1 had an Odbc namespace!
I'll take a look, thanks
