我正在尝试通过 CreateProcess() 在 Sublime Text 中打开一个文件，但构建显示错误 [英] I am trying to open a file in Sublime Text through CreateProcess() but the build shows errors

问题描述

STARTUPINFO         siStartupInfo;
PROCESS_INFORMATION piProcessInfo;

memset(&siStartupInfo, 0, sizeof(siStartupInfo));
memset(&piProcessInfo, 0, sizeof(piProcessInfo));

siStartupInfo.cb = sizeof(siStartupInfo);

if (CreateProcess("C:\\Program Files\\SublimeText2\\sublime_text",              
   " source.cpp",                       
    NULL,
    NULL,
    FALSE,
    CREATE_DEFAULT_ERROR_MODE,
    NULL,
    NULL,
    &siStartupInfo,
    &piProcessInfo) == FALSE)


    WaitForSingleObject(piProcessInfo.hProcess, INFINITE);


::CloseHandle(piProcessInfo.hThread);
::CloseHandle(piProcessInfo.hProcess);

我试图通过 CreateProcess 在 Sublime Text 中打开一个文件，但构建显示以下错误:

I am trying to open a file in Sublime Text through CreateProcess but the build shows the following errors:

const char *"类型的参数与LPWSTR"类型的参数不兼容.

argument of type "const char *" is incompatible with parameter of type "LPWSTR".

const char *"类型的参数与LPWCSTR"类型的参数不兼容.

argument of type "const char *" is incompatible with parameter of type "LPWCSTR" .

'BOOL CreateProcessW(LPCWSTR,LPWSTR,LPSECURITY_ATTRIBUTES,LPSECURITY_ATTRIBUTES,BOOL,DWORD,LPVOID,LPCWSTR,LPSTARTUPINFOW,LPPROCESS_INFORMATION)': 无法将参数 1 从 'const char [32]' 转换为 'LPCW>

'BOOL CreateProcessW(LPCWSTR,LPWSTR,LPSECURITY_ATTRIBUTES,LPSECURITY_ATTRIBUTES,BOOL,DWORD,LPVOID,LPCWSTR,LPSTARTUPINFOW,LPPROCESS_INFORMATION)': cannot convert argument 1 from 'const char [32]' to 'LPCWSTR' .

推荐答案

LPWSTR (Long Pointer to Wide STRing) 是 wchar_t*，而不是 char*.您有 3 个选项可以解决问题:

LPWSTR (Long Pointer to Wide STRing) is a wchar_t*, not a char*. You have 3 options to fix the problem:

1. 不要使用 UNICODE #defined 编译.
2. 使用CreateProcessA

3. 更改调用以使用宽字符串常量，并显式调用函数的 W 版本，如下所示:

1. Don't compile with UNICODE #defined.
2. Use CreateProcessA

3. Change the call to use wide string constants, and call the W version of the function explicitly, as in:

CreateProcessW(L"C:\\Program Files\\SublimeText2\\sublime_text", 
              //...

在这三个选项中，您应该使用第三个选项.

Of the three, the third option is the one you should use.
