字符串到LPCWSTR [英] string to LPCWSTR

问题描述

你好，

我正在使用ShellExecute打开具有以下功能的Web浏览器:

hello,

I am using ShellExecute to open a web browser with this function:

#include <windows.h>;


void google(string args)
{
    string URL ("http://www.google.com/search?q=");
    URL.append(args);

    ShellExecute(NULL, L"open", URL, NULL, NULL, SW_SHOWNORMAL);
}


</windows.h>

但我不断收到错误消息:
错误C2664:"ShellExecuteW":无法将参数3从"std :: string"转换为"LPCWSTR""

没有人知道如何将字符串更改为LPCWSTR或解决此问题的方法吗?

thanx

but I keep on getting the error message :
"error C2664: ''ShellExecuteW'' : cannot convert parameter 3 from ''std::string'' to ''LPCWSTR''"

does any one know how to change a string to a LPCWSTR or a way around this problem?

thanx

或者，您也可以使用:ShellExecuteA

or you can use: ShellExecuteA

转换为const char *首先使用.c_str()，然后使用char *加上static_cast，如果需要的话，最后转换为LPCWSTR.您还可以通过使用多字节字符集而不是Unicode来更改所需的类型，并且可以修改您需要转换为的类型.

Convert to const char * first use .c_str(), then char * with static_cast if needed, and finally convert to LPCWSTR if necessary. You also might be able to change the type required by using Multi-Byte Character Set instead of Unicode, and that may modify the type you need to cast to.
