怎样将CString字符串转化为PUSHORT和PULONG类型？

[hit1106]

我用GetDlgItemText(IDC_EDIT,Iohex);获取字符串后
再转成PUSHORT PULONG UCHAR USHORT ULONG这些形式，才能在函数中引用
比如CH367mReadIoByte(
ULONG iIndex,
PVOID iADDR,
PUCHAR oByte)函数中就需要将获取的字符串转化为PUCHAR，才能在函数中引用

(PUCHAR)CString1

CString::operator LPCTSTR operator LPCTSTR ( ) const; Return Value A character pointer to the string’s data. Remarks This useful casting operator provides an efficient method to access the null-terminated C string contained in a CString object. No characters are copied; only a pointer is returned. Be careful with this operator. If you change a CString object after you have obtained the character pointer, you may cause a reallocation of memory that invalidates the pointer.

那怎么将CString类型转化为PUSHORT呢？

[赵4老师]

#ifdef _UNICODE
 (PUSHORT)CString1
#else
 (PUCHAR)CString1
#endif
//或者干脆
(LPCTSTR)CString1

[赵4老师]

#include <afxdisp.h>
#include <windows.h>
#include <stdio.h>
int main() {
    CString cs;
    ULONG ul;

    cs="123";
    if (1==sscanf(cs,"%lu",&ul)) {
        printf("CString [%s] to ULONG is [%lu]\n",cs,ul);
    } else {
        printf("CString [%s] to ULONG fail!\n",cs);
    }

    cs="abc";
    if (1==sscanf(cs,"%lu",&ul)) {
        printf("CString [%s] to ULONG is [%lu]\n",cs,ul);
    } else {
        printf("CString [%s] to ULONG fail!\n",cs);
    }

    return 0;
}
//CString [123] to ULONG is [123]
//CString [abc] to ULONG fail!
//

怎么将CString类型转换为ULONG类型呢？

引用 3 楼 zhao4zhong1 的回复:

#ifdef _UNICODE
 (PUSHORT)CString1
#else
 (PUCHAR)CString1
#endif
//或者干脆
(LPCTSTR)CString1

你好！请问怎么将CString类型转换为ULONG类型呢？
