将负CString转换为DWORD [英] Converting negative CString to DWORD

问题描述

CString sHandle;
DWORD ClientHandle;

sHandle = _T("134");
CStringA pszCharacterString (sHandle);
ClientHandle = atoi(pszCharacterString); //client handle is 134

一切正常.但要这样:

This is working fine. But for this:

CString sHandle;
DWORD ClientHandle;

sHandle = _T("-134"); //a negative sign at front
CStringA pszCharacterString (sHandle);
ClientHandle = atoi(pszCharacterString); //this fails, client handle is 424967162

我如何实现它以使CString _T(-134")转换为DWord

How do i implement it for CString _T("-134") to convert to DWord

推荐答案

DWORD是 unsigned .因此424967162是(DWORD)(int)(-134)

另请参见: Two's Complement [

DWORDs are unsigned. so 424967162 is (DWORD)(int)(-134)

ClientHandle的类型为DWORD，这是无符号数字.只需使用从atoi()返回的int.

ClientHandle is of type DWORD which is an unsigned number. Just use an int as returned from atoi().
