Use the class library project.

Add the project that creates the DLL as a reference to the project that contains the .aspx files.

Alternatively, if the DLL exists outside the solution. Use the add reference dialog to find the created DLL.

Upcoming events:
* Glasgow: Mock Objects, SQL Server CLR Integration, Reporting Services, db4o, Dependency Injection with Spring ...
* Reading: Developer Day 5

Ready to Give up - Your help will be much appreciated.

There is no code to give you a sample of. It is all in the settings and project types you choose in Visual Studio.

To create a basic DLL, create a project of type Class Library.

To use that DLL in another project in the same solution use "Add Reference..." (right click on the project in the solution explorer to get that) and choose the project from the dialog box.

I think ASP.NET projects are slightly different, but off the top of my head I don't recall what you need to do.

So its i C# forum Smile | :)

I think you are asking about creating dll of WEB APPLICATION
By Publiching the WEB application you can create a precompile resources
What you want to do by creatng the dll of WEb application ?
Any other dll can be used in your application by simply clicking right click and
Add referennce then add your dll by browsing your machine

Thanks and Regards

Hi Razanabanu,
here is the code structure that is to be used to create your own dll file.

using System;
//other references

namespace sampledll
{
public class dllfile
{
public static void <function_name>()
{
// your code goes here
}
}
}

for example if this files name is dllfile.cs

then use the following compilation format

>csc /t:library dllfile.cs

this would generate dllfile.dll

Important point to be noted
1. dont use main function. a dll file should not have an entry point.
2. always use public static attributes for the functions.

If you can DREAM it
you can DO it

That is bollox!

You can put what ever interfaces, classes, structs, etc. you want in there. You are not limited to static methods. You do not have to call your class after the DLL name.

I have 3 classes Screen.cs having 3 fields and properties only, screenDb.cs having methods to communicate with database and ScreenService.cs which is the business layer. In ScreenService.cs class i have a method

public void AddScreen(int screen_id, string screen_name, int screen_capacity)
{
sdb.InsertScreen(screen_id, screen_name, screen_capacity);
}
but my requirement is to provide the arguments as objects of screen class...

need help..

plz.. Unsure | :~

You haven't shown what Screen.cs looks like so I'm going to guess.

public void AddScreen(int screen_id, string screen_name, int screen_capacity)
{
    Screen screen = new Screen(screen_id, screen_name, screen_capacity);
    sdb.InsertScreen(screen);
}

and ScreenDb.cs will have to change its InsertScreen method to look like this:

public void InsertScreen(Screen screen)
{
    // Do what is needed with screen and its parameters.
}

However, since you've not provided what all the relevant existins code is, this is just a best guess.

my screen.cs class is like:

using System;
using System.Collections.Generic;
using System.Text;

namespace Screen
{
public class Screen
{
int screen_id;
string screen_name;
int screen_capacity;

public Screen(int ScreenId, string ScreenName, int ScreenCapacity)
{

screen_id = ScreenId;

screen_name = ScreenName;

screen_capacity = ScreenCapacity;

}

public int ScreenId
{
get { return screen_id; }
set { screen_id = value; }
}

public string ScreenName
{
get { return screen_name; }
set { screen_name = value; }
}

public int ScreenCapacity
{
get { return screen_capacity; }
set { screen_capacity = value; }
}
}
}

and the method in ScreenDb class is:

public void InsertScreen(int ScreenId, string ScreenName, int ScreenCapacity)
{
DbCommand cmd = db.GetStoredProcCommand("insertscreen");
db.AddInParameter(cmd, "@sid", DbType.Int32, ScreenId);
db.AddInParameter(cmd, "@sname", DbType.String, ScreenName);
db.AddInParameter(cmd, "@sc", DbType.Int32, ScreenCapacity);
cmd.ExecuteScalar();
}

my requirement is writing a method that will call Insert screen method with arguments as object of screen clas

public void InsertScreen(Screen screen)

    string ScreenName = screen.ScreenName;
    int ScreenCapacity = screen.ScreenCapacity;
    // The rest of the method is as before...
}

I am using MsEnterprise block to communicate with database. But confused where to store the connection string if it is in app.config then how to access app .config and how to store the connection string.

need help

Re: enterprise Block

There is an Enterprise Library Configuration tool that comes with the Enterprise Library. Open the app.config file in the configuration tool and it will make the changes for you. If you prefer later you can edit it by hand.
