}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
catch (...)
{
try
{
throw Exception("");
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
}
if(g_bIsRunAgain)
{
AnsiString strPath;
STARTUPINFO StartInfo;
PROCESS_INFORMATION procStruct;
memset(&StartInfo, 0, sizeof(STARTUPINFO));
StartInfo.cb = sizeof(STARTUPINFO);
strPath = Application->ExeName;
if(!::CreateProcess(
(LPCTSTR) strPath.c_str(),
NULL,
