I'm new to visual basic. I'm trying to execute `.exe` file from VB. But I'm not getting the output. My `.exe` is having command line args. Following is my code

```
Private Sub Command1_Click()

    Shell "D:\FEP\extractFEPData.exe data.txt", vbNormalFocus

End Sub

```

In cmd prompt If I give command `extractFEPData.exe data.txt` It is parsing the file. But in VB after clicking command button nothing happens. 

Please help me.
