【方法】获取字符串资源中某个字符串的长度的方法

Floor 1 巨大八爪鱼 6/20/16 21:00
#include <stdio.h>
#include <Windows.h>
#include "resource.h"

int main(void)
{
    HINSTANCE hInst = GetModuleHandle(NULL);
    LPWSTR p = NULL;
    LoadStringW(hInst, IDS_STRING101, (LPWSTR)&p, 0);
    printf("长度为: %d\n", wcslen(p));
}

nBufferMax [in]
Type: int
The size of the buffer, in characters. The string is truncated and null-terminated if it is longer than the number of characters specified. If this parameter is 0, then lpBuffer receives a read-only pointer to the resource itself.

最后一个参数设为0,可以获得指向字符串资源的原始指针。
只针对LoadStringW函数有效,LoadStringA不行。因为字符串资源里面只有Unicode版本的内容,没有ANSI版本的内容。自然就不存在指向ANSI版本内容的指针。
