ScriptGetFBlockStatus Method - intrepidcs API
C/C++ declare - VB.NET declare - C# declare - Parameters - Return Values - Remarks - C/C++ example - VB.NET example - C# example

This method returns the run status of a specified function block within a script on a neoVI device.

C/C++ Declare

int _stdcall icsneoScriptGetFBlockStatus(void * hObject,  unsigned int iFunctionBlockIndex, int *piStatus);


Visual Basic .NET Declare

Public Declare Function icsneoScriptGetFBlockStatus Lib "icsneo40.dll" (ByVal hObject As IntPtr, ByVal fb_index As UInt32, ByRef piRunStatus As Int32) As Int32

C# Declare

[DllImport("icsneo40.dll")]
public static extern Int32 icsneoScriptGetFBlockStatus(IntPtr hObject, UInt32 fb_index, ref Int32 piRunStatus);

Parameters

hObject
    [in] Specifies the driver object created by OpenNeoDevice.

iFunctionBlockIndex
   [in] The index value of the function block to start

piStatus
   [out] 0 = stopped 1 = running

Return Values

1 if the function succeeded. 0 if it failed for any reason. GetLastAPIError must be called to obtain the specific error. The errors that can be generated by this function are:

NEOVI_ERROR_DLL_NEOVI_NO_RESPONSE = 75
NEOVI_ERROR_DLL_SCRIPT_INVALID_FUNCBLOCK_INDEX = 219
NEOVI_ERROR_DLL_SCRIPT_NO_SCRIPT_RUNNING = 226

Remarks

The script containing the specified function block must have been successfully downloaded to the neoVI using ScriptLoadScript. Execution of the script must have been started by using ScriptStartScript. The valid index values for function blocks within a script can be found in the cmvspy.vs3cmb.h file (Produced by Vehicle Spy. Please see Vehicle Spy documentation).

Examples

C/C++ Example:

int iRetVal;
int iRunStatus;
unsigned long lLastErrNum;

iRetVal = icsneoScriptGetFBlockStatus(hObject, Function_Block_1, &iRunStatus);
if(iRetVal == 0)
{
    printf("\nFailed to check function block status);
}
else
{
    printf("\nFunction block status = %s\r\n", iRunStatus == 0 ? "Stopped" : "Running");
}


C# Example:

Int32 iResult;
Int32 iStatus=0;

//Get Status of Function Block in CoreMini
iResult = icsNeoDll.icsneoScriptGetFBlockStatus(m_hObject, Convert.ToUInt32(cboFBToChange.SelectedIndex), ref iStatus);

if(iResult == 0)
{
    lblFBStatus.Text = "Failed to get CoreMini Status";
}
else
{
    switch(iStatus)
    {
        case (int)ScriptStates.SCRIPT_STATUS_RUNNING:
            lblFBStatus.Text = "CoreMini Function Block Running";
            break;
        case (int)ScriptStates.SCRIPT_STATUS_STOPPED:
            lblFBStatus.Text = "CoreMini Function Block Stopped";
            break;
        default:
            lblFBStatus.Text = "Unhandled State";
            break;
    }
}


Visual Basic .NET Example:

Dim iResult As Int32
Dim iStatus As Int32

'//Get Status of Function Block in CoreMini
iResult = icsneoScriptGetFBlockStatus(m_hObject, Convert.ToUInt32(cboFBToChange.SelectedIndex), iStatus)

If iResult = 0 Then
    lblFBStatus.Text = "Failed to get CoreMini Status"
Else
    Select Case iStatus
        Case SCRIPT_STATUS_RUNNING
            lblFBStatus.Text = "CoreMini Function Block Running"
        Case SCRIPT_STATUS_STOPPED
            lblFBStatus.Text = "CoreMini Function Block Stopped"
        Case Else
            lblFBStatus.Text = "Unhandled State"
    End Select
End If
