Execute .exe in SSRS Report - sql

Question

i want to execute a .exe in a SSRS Report from Microsoft Dynamics AX.
I tried so far to realize that over Custom Code and a Textfield with following Expression: =Code.StartProcess("test")
Public Function StartProcess(ByVal s As String) As String
Dim pHelp As New ProcessStartInfo
pHelp.FileName = "test.bat"
pHelp.Arguments = s
pHelp.UseShellExecute = True
pHelp.WindowStyle = ProcessWindowStyle.Normal
Dim proc As Process = Process.Start(pHelp)
Return "it works"
End Function
I get the error ":StartProcess is invalid. InvalidIdentifier"
As second try i use this:
="javascript:void(window.open('file://AX2012R2A/Share/batch.exe'))"
in an action expression.
This trial opened in the report the following message by clicking on the image:
My problem is now that I have to pass a parameter to the batch and then it doesn't work.
Have you any idea to help me?

Answer 1

I have solved my Problem.
As first step I mentioned, that also simple methods like:
Public Function StartProcess(ByVal s As String) As String
Return "it works"
End Function
brought the error: ":StartProcess is invalid. InvalidIdentifier"
As second step i found this link:

(perhabs you have to expand all messages).
As last step i have to create a Datamethod and then call it in an expression and it works.
The code in the datamethod isn't in VB.Net but in C#.
How this works, can you see here (Youtube)
Thank you all for your help.
