将WORD内容保存为BMP

准备工作

ClassWizeard->AddClass->From TypeLibrary 选择OFFICE安装目录下的msword.olb  导入_Application，_Document,Documents,Paragraphs,Range

第一步将WORD内容复制到剪贴板

BOOL CWordToJPG::CopyWordToClipboard(LPCTSTR lpszFileName)
{
	COleVariant vTrue(( short )TRUE), vFalse(( short )FALSE), vOpt(( long )DISP_E_PARAMNOTFOUND, VT_ERROR); 

	_Application wordApp = ((CMakeQLibExApp *)AfxGetApp())->GetWordApplication();
	//BOOL bRet = wordApp.CreateDispatch(_T("Word.Application"));

	Documents docs = wordApp.GetDocuments();
	
	COleVariant FileName(lpszFileName);	
	_Document tempDoc = docs.Open(FileName,vFalse,vTrue,vFalse,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt,vOpt); 
	
	Paragraphs tempPgs = tempDoc.GetParagraphs();
	Range aRange = tempDoc.Range(vOpt,vOpt);
	aRange.Copy();


	aRange.ReleaseDispatch();


	tempPgs.ReleaseDispatch();

	tempDoc.Close(vOpt,vOpt,vOpt);
	tempDoc.ReleaseDispatch();

	docs.ReleaseDispatch();


	return TRUE;
