That is a bit of redundancy.

You could, but you may run into versioning nightmares.

You could, but someone could look into the code and try to hack a workaround.

Call .Net 2005 DLL in .Net 2003

I am not 100% sure. It is something that does vary from software shop to software shop.

Why would you want to use it in 1.1 when you could code it in 2.0 and have all the advantages of the extra features and better IDE?

You'll need to install the .Net 2.0 framework anyway so why not just use that?

I have some applications which is already developed in Framework 1.1 and as of now its not posible to move to Framework 2.0.

Have you tried running the solution from 1.1 through the converter to make it 2.0?

The simple answer is you can't. C# 2.0 (from VS 2005) uses .NET 2.0 while VB.NET 2003 uses .NET 1.1. These are different runtimes and are not compatible with each other. Beyond that, you can't have one application that loads two different versions of the runtime.

As a hack you could load it as an out of process COM server, but it's bad and wrong, just upgrade the damn app already :P it'll be worth it in the long run. There were very few breaking changes between 1.1 and 2.0 so theres not much excuse for not upgrading.

Thanks to All of you.

After doing lot of R&D and Spending lot of time on it, finally I come to the decision that I will upgrade existing applications to Framework 2.0. Frown | :(

Thanks Again.

I have a GUI utility and it connects to a sql server 2005 database. All of the connection code has been generated by the IDE.

I have 2 databases one for produciton and one for development. How can I switch the connection string? I am currently doing it in the Settings.Designer.cs file and checking for

#if DEBUG
//use the dev server
#else
//use the prod server
#endif

however everytime i alter the settings.settings file the IDE rewrites the Settings.Designer.cs file.

this is how the code currently works:

currently when i start my application the connection string is initialized like this:
this is called:
internal System.Data.SqlClient.SqlConnection Connection {
get {
if ((this._connection == null)) {
this.InitConnection();
}
return this._connection;
}
which calls this:
private void InitConnection() {
this._connection = new System.Data.SqlClient.SqlConnection();
this._connection.ConnectionString = global::DGView2.Properties.Settings.Default.ProdConnectionString;
}
which calls this:
public string ProdConnectionString {
get {
return ((string)(this["ProdConnectionString "]));
}
}

app.config file:

<connectionStrings>
<add name="DGView2.Properties.Settings.ProdConnectionString"
connectionString="Data Source=localhost;Initial Catalog=MyDatabase;Integrated Security=True"
providerName="System.Data.SqlClient"
<add name="DGView2.Properties.Settings.DevConnectionString" connectionString="Data Source=localhost\DEV;Initial Catalog=MyDatabase;Integrated Security=True" />

</connectionStrings>

I guess part of the problem is that this line of code:

this._connection.ConnectionString = global::DGView2.Properties.Settings.Default.ProdConnectionString;

is always calling: public string ProdConnectionString

so in my Settings.Designer.cs file I have set it up this way:

public string ProdConnectionString {
#if DEBUG
get { return ((string)(this["DevConnectionString"]));}
#else
get { return ((string)(this["ProdConnectionString"]));}
#endif
}

I am not convinced that this is the best way to do it. The ideal situation I think would be to use the desired property based on DEBUG or RELEASE in the call to the connection string:

#if DEBUG
this._connection.ConnectionString = global::DGView2.Properties.Settings.Default.DevConnectionString;
#else
this._connection.ConnectionString = global::DGView2.Properties.Settings.Default.ProdConnectionString;

#endif

however there are just to many instances of this therefore making it less efficient.

any suggestions?

thx

You may need to look in the App.Config file...

The normal way of doing this is to just use one setting. You change the config file, so that you have a debug version and a release version.

Deja View - the feeling that you've seen this post before.

I second what Pete said - use one setting, called ConnectionString and edit the file depending on whether you want it to work on Dev or Prod.

Not sure, but as an observation, I wouldn't have the password out in plaintext when you have your program go live Smile | :)
