Pass Parameter to an Application

[mahmood]

Hi everybody...

I want to develop an application using VB.NET..
my application will run from another application developed using oracle forms...
my application should recieve username, password , and other information from the other application..
the problem is how to recieve these information as parameters?

I assume you want to create a .NET application with a .exe extension (a true application not a component).

I dont know much about running external apps from Oracle forms, but I presume you have to execute the application by its name. If this is the case then you can use normal command line parameters.

Eg. "C:\myapp.exe param1=value1 param2=value2"

You can access the parameters using "Microsoft.VisualBasic.Command".

You will need to parse the string to get the parameter values.

When you find the solution, please post the code required to call the application from Oracle Forms. I am maintaining old Oracle Forms 3, so I am interested to see how its done now days.

The application must have Sub Main() method as entry point of the application with paramters (I think it's the same as in C# app) .

Yes. It's an awful idea to use the Compability namespace one when you can use a builtin one

I do not think you need a Sub Main i could be wrong but in vb 6 you could call Command anywhere.

How will the syntax look like then ?

[Tewl]

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        MsgBox(Microsoft.VisualBasic.Command())
    End Sub

Ok , can you pass argus to the formload event in commandline ,like this:
myapp.exe helloworld
?

That's not the point. The point is if you have a built-in way in .NET framework why in the world would you use the compability namespace?

[Tewl]

I import Microsoft.VisualBasic for many things such as left and right why would it matter.

[PT Exorcist]

I really don't get why would you still want Left() and Right() functions in VB.NET. You have .Substring() method that does what you need, if yo uwant Left()/Right() you could even implement it in a class made by your own(though i NEVER really needed it, i find the .Substring() method way best) removing the Compability namespace depency. Sure it is in .net framework but until when? And having in consideration that all that's there exists in equal or similar way in the .net framework I think it's a shame to use it :S

[Tewl]

I suppose. I don't use vb .net much anyway, I prefer C#

[Pirate]

if (YouHaveTo()) 
{
Use ("Microsoft.VisualBasic.dll")
}else{
Use ("string methods")
}

You can use Environment.GetCommandLineArgs()

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  Dim UserName As String = Environment.GetCommandLineArgs(1)
  Dim Password As String = Environment.GetCommandLineArgs(2)
  etc.
