如何单步执行外部程序

for c++builder,用于VC应该把消息框改一下就可以了

void contour(void){

char ln[100];

int Make;

char str[100]="";

char *tip="不能执行：";

sprintf(ln,"%s\\%s",GetCurrentDir(),"watson.exe");

char path[100];

sprintf(path,"%s",GetCurrentDir());

chdir(path);

//ShowMessage(ln);

STARTUPINFO startinfo;

PROCESS_INFORMATION procInfo;

strcat(str,tip);

strcat(str, ln);

GetStartupInfo(&startinfo);

startinfo.dwFlags =STARTF_USESHOWWINDOW;

startinfo.wShowWindow=SW_HIDE ;

Make=CreateProcess(NULL,ln,NULL,NULL,false,0,NULL,NULL,&startinfo,&procInfo);

if (!Make)

{

MessageBox(NULL, str, "提示", MB_OK);

}

WaitForSingleObject(procInfo.hProcess, INFINITE);

}
