The VB.NET program often gets stuck during readings.

hi：

I use E5052B and use a network cable link.（TCPIP0::192.168.1.231::inst0::INSTR）

This program is often stuck. And no error.

Private Sub E5_btnJTE_Click(sender As Object, e As EventArgs) Handles E5_btnJTE.Click
status = viVPrintf(vi, ":CALCulate:PN1:TRACe1:FUNCtion:INTegral:DATA?" + vbCrLf, 0)
status = viVScanf(vi, "%t", strRes) 
Dim outtext() As String = Split（strRes， ","）

Dim show_str As String = “”
show_str += outtext(4) + vbCrLf

VI_txtfinal.Text = VI_txtfinal.Text & show_str

End Sub

The program has stopped working

Hi xiao,

In order to better troubleshoot this question, I'd like to know what version of Visual Studio and Measurement studio you are using, as well as a screenshot of the error you are getting. Also, when during execution does the program stop? I'd like you to debug the code and step through it to see where the failure occurs. Also it will be much easier to troubleshoot if you could attach a copy of your code to your next response, since it will give us better insight than a small code snippet

thanks

I have found a solution.Add an if statement

If status = VI_SUCCESS Then

Dim outtext() As String = Split（strRes， ","）

Dim show_str As String = “”
show_str += outtext(4) + vbCrLf

VI_txtfinal.Text = VI_txtfinal.Text & show_str

End If

in debug mode show：

error occurred in document statechange handler

The value returned is -1073740940 (0xc0000374).
