Swatch Programming

Question

I have written an file format plug-in for custom files produced by a bespoke design package. This works fine but find I just can't add, change, delete or in any other way affect the document swatch. I want to delete the current colours and add my own colours which are contained in my custom file (Colours and descripions). I've tried everything but it seems like the swatch isn't loaded or something similar when my file imports - but I'm probably missing something obvious!
Can someone please tell me how to load a set of colours into the swatch when I load my custom file and/or provide some sample code.
I'm using Illustrator CS2 with Windows XP...and MS Visual Studio 2005
Thanks in anticipation!

Just started w/ CS3 SDK (beta) This is just test code but it does seem to work.
// these look like the working color space selection profiles
AIColorProfile rgb, cmyk, gray;
Error = sAIDocument->GetDocumentProfiles(&rgb, &cmyk, &gray);
// only one is valid
ai::UnicodeString name;
if (rgb)
Error = sAIOverrideColorConversion->GetProfileName(rgb, name);
else if (cmyk)
Error = sAIOverrideColorConversion->GetProfileName(cmyk, name);
else
Error = sAIOverrideColorConversion->GetProfileName(gray, name);
string s = name.as_Roman();
short colorModel;
Error = sAIDocument->GetDocumentColorModel(&colorModel);
// attempt to find a color in the swatch palette and if I find it get it's color values
ai::UnicodeString colorName("Atomic Red GCS-293");
AICustomColorHandle colorHandle;
AICustomColor color;
// find our color name in the doc's swatch
Error = sCustomColor->GetCustomColorByName(colorName, &colorHandle);
if (Error == 0)
// found it, get it's color
Error = sCustomColor->GetCustomColor(colorHandle, &color);
else
// din't not find it, create a color
color.c.rgb.red = 0.7685;
color.c.rgb.green = 0.051;
color.c.rgb.blue = 0.051;
color.flag = kCustomSpotColor;
color.kind = kCustomThreeColor;
Error = sCustomColor->NewCustomColor(&color, colorName, &colorHandle);
AIDocumentHandle document = NULL;
Error = sAIDocument->GetDocument(&document);
AISwatchListRef swatchList;
Error = sSwatchList->GetSwatchList(document, &swatchList);
AISwatchRef swatch = NULL;
swatch = sSwatchList->GetSwatchByName(swatchList, colorName);
if ( !swatch )
swatch = sSwatchList->InsertNthSwatch(swatchList, -1);
if ( swatch )
Error = sSwatchList->SetSwatchName(swatch, colorName);
int cCount;
AIColor aiColor;
aiColor.kind = kCustomColor;
aiColor.c.c.tint = 0.0f;
aiColor.c.c.color = colorHandle;
Error = sSwatchList->SetAIColor(swatch, &aiColor);
cCount = sSwatchList->CountSwatches(swatchList);
cCount++;
Hope this helps
