Save .ai file as .svg without save as prompt

So here is code snippet to do this. I had to do export file instead of save as.

  AIActionParamValueRef paramValueRef = NULL;

  sAIActionManager->AINewActionParamValue(&paramValueRef);

  ai::UnicodeString name = ai::UnicodeString("C:\\Users\\mypc\\Desktop\\test\\testfile.svg");

  ai::FilePath path(name);

  sAIActionManager->AIActionSetStringUS(paramValueRef, kAIExportDocumentNameKey,path.GetFullPath());

  sAIActionManager->AIActionSetString(paramValueRef, kAIExportDocumentFormatKey, kAISVGFileFormat);

  sAIActionManager->AIActionSetString(paramValueRef, kAIExportDocumentExtensionKey, kAISVGFileFormatExtension);

  sAIActionManager->AIActionSetBoolean(paramValueRef, kAIExportDocumentSaveMultipleArtboardsKey, false);

  sAIActionManager->PlayActionEvent(kAIExportDocumentAction,  kDialogOff,  paramValueRef);

This few methods should help! Using Value parameter block (VPB) - a container for action parameters.

@see AIActionManagerSuite

void ActionHelper::VPB::SetSaveDocumentAsName(const ai::FilePath& name) {     SDK_ASSERT(sAIActionManager);     ASErr result = sAIActionManager->AIActionSetStringUS(this->fActionParamValueRef, kAISaveDocumentAsNameKey,    name.GetFullPath());     aisdk::check_ai_error(result); }

void ActionHelper::VPB::SetSaveDocumentAsGetParams(ASBoolean getParams) {        ASErr result = sAIActionManager->AIActionSetBoolean(this->fActionParamValueRef, kAISaveDocumentAsGetParamsKey, getParams);     aisdk::check_ai_error(result); }

ASErr ActionHelper::SaveDocumentAs(const ai::UnicodeString& name, DocumentActionHelper::VPB& vpb) {     ASErr result = kNoErr;     try {                 ai::FilePath path(name);                vpb.SetSaveDocumentAsName(path);         // Enable dialogs parameter.                vpb.SetSaveDocumentAsGetParams(false);                 ActionDialogStatus dialogStatus = name.empty() ? kDialogOn : kDialogOff;                        result = this->SaveDocumentAs(dialogStatus, vpb);         aisdk::check_ai_error(result);     }     catch (ai::Error& ex) {         result = ex;     }        return result; } ASErr ActionHelper::SaveDocumentAs(ActionDialogStatus dialogStatus, AIActionParamValueRef parameters) {     ASErr result = kNoErr;     try     {         SDK_ASSERT(sAIActionManager);         result = sAIActionManager->PlayActionEvent(kAISaveDocumentAsAction, dialogStatus, parameters);         aisdk::check_ai_error(result);     }     catch (ai::Error& ex)     {         result = ex;     }        return result; }

I have this snippet do exact thing you want. Though it uses extend-script and not c++.

This does not give you save as dialogue.

// Exports current document to dest as an SVG file with specified
// options, dest contains the full path including the file name
function exportFileToSVG (dest) {
if ( app.documents.length > 0 ) {
var exportOptions = new ExportOptionsSVG();
var type = ExportType.SVG;
var fileSpec = new File(dest);
exportOptions.embedRasterImages = true;
exportOptions.embedAllFonts = false;
exportOptions.fontSubsetting = SVGFontSubsetting.GLYPHSUSED;
app.activeDocument.exportFile( fileSpec, type, exportOptions );
}
}

I hope this helps.
