Question

VC2010调用是控件DLL 接口，这个调用过程和AutoCAD Arx开发是一样的。

命令函数实现：

.h文件：

class CTestCommands
{
static void TextToCurve();
}

.cpp文件：

void CTestCommands::TextToCurve()
{
	ads_name entName;
	ads_point pt;
	if(acedEntSel(_T("选择需要编辑的文字:"),entName,pt) != RTNORM)
	{
		return;
	}
	AcDbObjectId objId;
	if(acdbGetObjectId(objId,entName) != Acad::eOk)
		return;

	AcDbObjectPointerspText(objId,AcDb::kForWrite);
	if(spText.openStatus() != Acad::eOk)
		return;


	McDbVoidPtrArray aryCurve ;
	if(!MxDraw::TextToCurves(spText.object(),aryCurve) )
		return;

	for(int i = 0; i < aryCurve.length();i++)
	{
		McDbEntity* pEntity = (McDbEntity* )aryCurve[i];

		MrxDbgUtils::addToCurrentSpaceAndClose(pEntity);
	}
	spText->erase();
}

注册一个命令：

acedRegCmds->addCommand(_T("SysCmd"), _T("TextToCurve"), _T("TextToCurve"), 1, TextToCurve);

执行命令：

acDocManager->sendStringToExecute(MxDraw::GetDatabase(m_hDrawOcx)->GetDocument()
		,_T("TextToCurve") );
