If the VB 6 app reads data stored in excel format then save the data from the web form with an excel format. Then the VB6 app can show the data given the file.
If I see ur problem correctly

I am sorry for not being clear. I will explain it once again.
I have a VB6 application which has Excel embedded in its Form. Now there is an ASP.NEt application which has a web page with a Save button.
When the user enters data on the Web Page and hits on Save button, 2 Actions has to happen.
1) The data will be saved in Oracle DB
2) The same data needs to be loaded in the Excel present in the VB application.

Action (1) is easy with no problems
Action (2) is my problem as I am not getting the reference of the VB application from C# (2.0)

Please let me know if there is some way to do it.

I am unsure if I understand what you are trying to do. You have a VB6 application which holds the excel stuff. Are you trying to save the data from your ASP application, and then send a message to the VB6 app to read the file after it has been saved? Or are you just saving it, and then letting the user load the data whenever?

start external app, but in a sync way

Hi.

How do you start synchronously an external application?

My program must suspend execution and wait for the external app to close itself and only then resume execution.

Thanks.

Take a look at the Process class.

Yes, I know how to start it using the Process class.

But by default, that starts the external application asynchronously, which is not what I want.

Hello,

Have you had a look at the "WaitForExit()" method of the process class?
Or do you mean something completely different?

All the best,

Martin

As Martin# stated below, I was thinking you could WaitForExit() from the Process class. I didn't notice you wanted to run the process synchronously, despite being in bold Smile | :)

I am unsure if the process can be ran synchronously.

That's what the select did. I thnk you need to add .Value or something like that.

I think it has to be dataset.tables[0].rows[0].ToString();

Also, not more than 4 threads down you have the EXACT same thread, with answeres in it for you. Why did you start a new one, people can still see that. It just makes you look impatient and rude. Read the forum rules

Rows is the collection of all rows in your datatable. The first [0] is the row specifier. So lets say you have

Justin Perez
Lourens G
Titus Perez

Rows[0] Will return the first Row, containing Justin Perez. The second specifier is for which column you would like to retrieve. So Rows[0][1] Will return Perez. First row, Second column.

Messaging between objects?

Hi,
I have this simple board game, has a form object which holds all other objects in it, the board being one of the objects added as a control to the form. Now I want to let the form know when something specific happens on the board (to adjust the score label which is on the form as a control as well).

Thanx
