Origin Version (Select Help-->About Origin): v.7.5853(B853)
Operating System: WindowsXP Pro
Hello,
Code written below was working perfectly for OriginPro 7 SR0, but it does not import file for the current version of Origin (see above). Does anyboly have an idea what might be wrong? It looks like program can not open image file.
CODE:::
BYTE Buffer[5000000];
Dataset ds;
ds.Attach("Curves", 0);
ds.SetSize(40);
for(i=0; i<40; i++)
ds[i]=0.2*i-4;
ds.Detach();
ds.Attach("Curves",1);
ds.SetSize(40);
FileName.Format("c:\\temp\\spectr\\m%d_ori.sf0", FileIndex);
if (!ImageFile.Open(FileName, file::modeRead))
{
ImageFile.Close();
return;
}
ImageFile.Read(Buffer, 5000000);
ImageFile.Close();
for (Point = 0; Point < 1; Point++)
{
for (i=0;i<40;i++)
{
BYTE h, l;
short a;
a = Buffer[i*2*2500 + Point*2]*256 + Buffer[i*2*2500 Point*2 + 1];
ds[i] = a;
}
}

Thank's a lot. file::GetLastError command really helped. |

To find out why the file::Open method failed you need to call the file::GetLastError method. The error codes and descriptions are defined at the top of Origin C's file.h.

Origin Version (Select Help-->About Origin): v.7.5870(B870)
Operating System: WindowsXP Pro
I wrote function for testing whether the file is opening or not, the answer is always "Failed to open file ...". Function OpenFile() was taken from the example.
Complete code:::
#include <Origin.h>
///////////////
int OpenFile(string strFileName);
void LoadSPImage(int FileIndex);
///////////////
file fScan;
string strFileName;
///////////////
int OpenFile(string strName)
{
strFileName = strName;
if( fScan.Open(strFileName, file::modeRead) )
{
printf("Opened file %s\n", strFileName);
return 0;
}
printf("Failed to open file %s\n", strFileName);
return 1;
}
void LoadSPImage(int FileIndex)
{
string FileName;
FileName.Format("c:\\temp\\spectr\\m%d_ori.sf0",FileIndex);
OpenFile(FileName);
fScan.Close();
}
Please tell me why file is failing to open? |

Where is the declaration for ImageFile?
Did the call to ImageFile.Open succeed?
Did the call to ImageFile.Read succeed?
More information is needed to diagnose the problem.
