How do I define a data type as an "IMG_ERR"?

Question

For instance
imaq1394ConfigureAcquisitionCW (sessionId As SESSION_ID,
continuous As Long, bufferCount As Long) As IMG_ERR

Answer 1

Hi Timmkish,
Can you run the "Low Level Grab1394.vbp" example (probably in C:\Documents and Settings\All Users\Documents\National Instruments\NI-IMAQ for IEEE-1394\Examples\VB\Low Level Grab1394)? This example References "NI-IMAQ for IEEE 1394" (imaq1394.dll) and sets a variable to IMG_ERR. It also uses imaq1394ConfigureAcquisitionCW.
Just a snippet...
Dim sid As SESSION_ID
Dim errorCode As IMG_ERR
Dim myImage As New CWIMAQImage
Dim BufferNumber As Long
Private Sub GrabButton_Click()
    CWIMAQViewer1.Attach myImage
    errorCode = imaq1394CameraOpen2(CameraName.Text, IMG1394_CAMERA_MODE_CONTROLLER, sid)
    If (errorCode <> IMG1394_ERR_GOOD) Then
        GoTo Error
    End If
    '  Configure a continuous acquisition (continuous = 1)
    '  using 3 hardware buffers (bufferCount = 3).
    errorCode = imaq1394ConfigureAcquisitionCW(sid, 1, 3)
    If (errorCode <> IMG1394_ERR_GOOD) Then
        GoTo Error
    End If
