I am using a BaseFile to create presets for my plugin.  The plugin writes all of the AM descriptions to a file and calls those from the file when a preset is loaded.  This works great unless I use a LONG or dropdown box.   When I try to call the long from the file I get nothing.  Here's the code I am using to write to the file and read from the file.

WRITING TO THE BASEFILE

  
  
  //Open the BaseFile for writing.  
  bf->Open(file, FILEOPEN_WRITE, FILEDIALOG_IGNOREOPEN, BYTEORDER_INTEL, MACTYPE_CINEMA, MACCREATOR_CINEMA);  
  
  
//Rotation Direction  
      if (bc->GetLong(PLANETX_GENERAL_ROTATION_DIRECTION) == PLANETX_GENERAL_ROTATION_CLOCKWISE)  
      {  
          bf->WriteLong(bc->GetLong(PLANETX_GENERAL_ROTATION_CLOCKWISE));  
      }  
      else  
      {  
          bf->WriteLong(bc->GetLong(PLANETX_GENERAL_ROTATION_COUNTER_CLOCKWISE));  
      }  

READING THE BASEFILE

  
  
//Open the BaseFile for Reading.  
  
 bf->Open(file, FILEOPEN_READ, FILEDIALOG_IGNOREOPEN, BYTEORDER_INTEL, MACTYPE_CINEMA, MACCREATOR_CINEMA);  
  
//Rotation Direction  
LONG rotdir;  
bf->ReadLong(&rotdir);  
bc->SetLong(PLANETX_GENERAL_ROTATION_DIRECTION, enrot);  

Any reason why it wouldn't read the data stored in the LONG that holds the dropdown box options.  ?  Am I using it wrong?

Thanks,

Shawn

Also..  How would I store the information in a gradient in the BaseFile?

Thanks,

This doesn't work because PLANETX_GENERAL_ROTATION_CLOCKWISE is not an element in the description, it's one of the options in the dropdown. Therefore it can't be accessed through the base container and written to the file, which means it can't be read back, either. Do:

bf->WriteLong(bc->GetLong(PLANETX_GENERAL_ROTATION_DIRECTION));

instead and it should be okay.

Can't help with the gradient, I'm afraid!

btw IO solved the gradient problem ...

save to file.

  
  
//Atmosphere Color

      LONG knotCount = atmColor->GetKnotCount();  
      bf->WriteLong(knotCount);  
  
      for(int i = 0; i < knotCount; i++){  
          GradientKnot knot = atmColor->GetKnot(i);  
          bf->WriteLVector(knot.col);  
          bf->WriteLReal(knot.pos);  
      }  
  
      //Transparency Color  
      Gradient *atmtColor =(Gradient* )bc->GetCustomDataType(PLANETX_ATMOSPHERE_TRANSPARENCY, CUSTOMDATATYPE_GRADIENT);

Looking again at the read method for the setting, you're reading into a variable called rotdir, but storing the variable named enrot into the base container.
