Hi All

We are developing a new project in C# and it is being migrated from VB6 which uses client server technology with SQL server 2k.
I am developing a DLL which gives data a part of the VB6 application to the new new c# project developed (bridge kind of stuff that links these two application which retrieves data from SQL server and give it to vb6 dll)

I wanted to know what is the best method of giving back the results (in the form of recordsets/xml or whatever) from the dll to c# program Confused | :confused:

Kindly help Eek! | :eek:

Thanks

Siva

XML, because a dataset can import it.

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

C# and Windows'98

I’m new in all this, but tell me – I develop an application in C# - is it possible to run this application under
Windows 98 or Millenium? What shall I do or where can I read about this?
Thanks!

Yes, so long as it has the .NET framework installed. You can only develop under an NT based OS though, that means W2000 or XP.

Christian, I don't want to be bothersome, but do they really need the whole .NET Framework? Smile | :)

Don't they only need the .NET redistributable files (20mb)in able to run C# apps? Smile | :)

This has been discussed many times before, but. Because he was newbie I wanted to say this. Hope you understand my point, Christian.

Also I've read that you *can* develop on win98 with C# because the redistibuteable comes with the C# compiler. Allthough I've never used it like this...

Which compiler?
If you mean csc you can use it on Win98, but the Visual Studio .NET is only a NT capable IDE as Christian said.

actually yes that is the the compiler but I fail to see where he said anything about Visual Studio .NET Poke tongue | ;-P

as far as I know http://www.icsharpcode.net/OpenSource/SD/default.asp[^]should run on win98...

That is an IDE. Not a compiler. I don't think there is more than the csc compiler for C#....

Sure here is a quick example:

string sql;
sql = GetSearchString();<font color=green>  //function that creates my SQL statement</font>
try
{
	string myConnString = "Provider=Microsoft.Jet.OLEDB.4.0;" 
         +  "Data Source=" + @"C:\Documents and Settings\User\Desktop\phonebook\phonebook.mdb";
	OleDbConnection myConnection = new OleDbConnection(myConnString);
	myConnection.Open();
	OleDbCommand myCommand = new OleDbCommand();
	myCommand.Connection = myConnection;
	myCommand.CommandText = sql;
	OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(myCommand);
	DataSet myDataSet = new DataSet();
	myDataAdapter.Fill(myDataSet);
	this.dataGrid1.DataSource = myDataSet;
	this.dataGrid1.Visible = true;
	myConnection.Close();
}
catch(Exception err)
{
	MessageBox.Show("An error has occured\n\n" + err.Message + "\n" + err.Source + "\n", "Phone Book Error");
}

Hope this helps. Smile | :)

C# Office Addins

Can anybody please help on a problem I am having?

My problem is that I need to be able to get the name of the application that my AddIn has been loaded into (Word, Excel etc.). I assume I use the application object that gets passed into the OnConnection method, but I am unsure how to get the reference to the "Name" property.

Does anybody have any samples or references that might help me in my endeavours?

Have a look at my website: http://www.chrisormerod.cjb.net

Hi Chris,

There are lot of references / articles on msdn on how to go about writing addins using managed code.
For starting take a look at this

Also have a look at this [^]
article, which might help you with your specific problem.
Hope this helps.
