That's fine, can you give yourself?
LRet=ReadProcessMemory (pHandle, ByVal & amp; H1529BC, lngTouZhuZhuang, 4 & amp; , 0 & amp;)

CodePudding user response:

You don't put the function statement posted, who knows what is this error,

Examples of such as API - Guide, ReadProcessMemory inside the second parameter is declared as ByVal, originally you call that way is right,
