In above workflow i’m adding a sign image to pdf it works fine, but I wants to capture the (error msg / sucess code) from exe file & save it in variable.
I attached Workflow & code file above can anybody suggest me changes in it?
Hi @pravin_bindage ,
If you want to capture the Error which might happen in the
Invoke Code activity, then you would have to Enclose the Statements in a
Try Catch Block and in the Catch you would need to assign the Exception variable outside of the activity using an out argument :
Try Process.Start("http://www.microsoft.com") Catch ex As Exception out_Exception = ex End Try
out_Exception is a
System.Exception type argument which has a direction
I used invoke to run exe file. If error is in exe file execution then what can we do?
Can you check the following sample? This output stabdard output and standard error of the process.
Dim p As New Process() p.StartInfo.FileName = System.IO.Path.Combine(System.Environment.GetEnvironmentVariable("USERPROFILE"),"AppData\Local\Programs\UiPath\Studio\UiPath.LicenseTool.exe") p.StartInfo.Arguments = "info" p.StartInfo.UseShellExecute = False p.StartInfo.RedirectStandardOutput = True p.StartInfo.RedirectStandardError=True p.Start() stdout = p.StandardOutput.ReadToEnd() stderr = p.StandardError.ReadToEnd() p.WaitForExit() p.Close()

Dim process As New Process() process.StartInfo.FileName = Chr(34) + ExePath + Chr(34) process.StartInfo.Arguments = Chr(34) + InputFile + Chr(34) process.StartInfo.RedirectStandardOutput = True process.StartInfo.RedirectStandardError = True process.StartInfo.UseShellExecute = False process.Start() process.WaitForExit() Dim exitCode As Integer = process.ExitCode Dim outputMessage As String = process.StandardOutput.ReadToEnd() Dim errorMessage As String = process.StandardError.ReadToEnd() If exitCode = 0 Then ' Successful execution ' Store outputMessage in outputVariable outputVariable = outputMessage Else ' Error occurred ' Store errorMessage in errorVariable errorVariable = errorMessage End If
Done with this code now it capturing error
