[br]I'm having trouble using the image.import functions (both through Origin C and LabTalk).  The code I use is essentially like what's pasted below (i'm certain there isn't a semantic problem in the code).  The problem is that the images are only successfully imported occaisionally, and after one import fails (no data is copied into the matrix), Origin has to be restarted before an import will succeed.  Half of the time the import will not succeed at all, even after the computer is rebooted.  I've even experienced this without recompiling my code, on different days.  Has anyone experienced a problem like this?

bool import_image(LPCSTR lpcszMatrix, LPCSTR lpcszFile)
{
  Page pg(lpcszMatrix);
  if( !pg || EXIST_MATRIX != pg.GetType() )
    return false;
  string strPage = lpcszMatrix;
  if( !lpcszFile )
    return false;
  using Image = LabTalk.Image;
  Image.FileName$ = lpcszFile;
  int iErr = Image.Import.Matrix(strPage);
  if( iErr )
  {
    printf("Import Error %d\n", iErr);
    return false;
  }
  pg.LT_execute("matrix -ii"); // show matrix as image
  return true;
}

Iris_Bai	Posted - 07/27/2004 : 10:14:43 PM Hi, I cannot reporduce your problem. Using the codes below can import image into matrix successfully each time in 7.5 853. void test() { MatrixPage mp; mp.Create("Origin"); import_image(mp.GetName(), _L("C:\\bs.bmp")); } Iris
