以下是用ODK获取DSN的代码
LPCTSTR GetDSN(int dsnType)
{
HANDLE hDSN = NULL; //declare date source handle
DM_PROJECT_INFO Info;
char prjName[_MAX_PATH+1];
DM_DIRECTORY_INFO dmDirInfo;
CMN_ERROR Error;
char File_path[100];
char DSNRC[100];
char DSNRT[100];
BOOL ret;
char szText[255];

DMGetRuntimeProject(prjName,_MAX_PATH,&Error);
memset(&Info, 0, sizeof(DM_PROJECT_INFO));
memset(&Error,0,sizeof(CMN_ERROR));
ret = DMGetProjectInformation ( prjName, &Info, &Error);
if(FALSE == ret) {goto over;}
else
{
sprintf(DSNRC, "%s",Info.szDSNName);
sprintf(DSNRT, "%sR",Info.szDSNName);
}
over:;
if (dsnType==0) return DSNRC;
if (dsnType==1) return DSNRT;
}
