vc这句代码在PB中怎么写
VC:
extern int WINAPI MXLoadFeatureFromFile(char* strFeatureName,unsigned char*FeatureBuf);

CString sFilePath;//./
unsigned char TempletInfo[10000*256];
while (bWorking)
{
ret = MXLoadFeatureFromFile((char*)(LPCSTR)sFilePath,&TempletInfo[i*256]);//./
}


PB:
Function int MXLoadFeatureFromFile(string strFeatureName,ref string FeatureBuf) Library 'MXOTDLL.dll'

string ls_FilePath,ls_FeatureBuf
ls_FeatureBuf = space(256 * 10000)

问：上面VC的循环部分，PB怎么写，谢谢
