带有错误字符串的 NSIS 插件

问题描述

我尝试用 C++ 开发一个 NSIS 插件.

I've tried to develop an NSIS Plugin in C++.

这是我从 NSIS 设置信息的方法:

Here is my method to set informations from NSIS:

void __declspec(dllexport) SetCredentials(HWND hWndParent, int string_size, TCHAR *variables, stack_t **stacktop, extra_parameters *extra) {
    EXDLL_INIT();

    server      = getuservariable(INST_0);
    port        = myatou(getuservariable(INST_1));
    database    = getuservariable(INST_2);
    username    = getuservariable(INST_3);
    password    = getuservariable(INST_4);

    MessageBox(hWndParent, server, L"Info", MB_OK); // Here is the problem
    setuservariable(INST_0, server);
}

示例:

OutFile "Example.exe"
BrandingText " "

Section
   MySQL::SetCredentials "localhost" 3306 "banananode" "root" ""
   Pop $0
   MessageBox MB_OK "Server: $0" ; Returns the server value...
SectionEnd

问题是，当我尝试打印 server 变量时，将显示中文字符，而不是正确的文本:

The Problem is, when i try to print out the server variable, chinese characters will be shown, not the correct text:

当我用 setuservariable(INST_0, server); 返回值时，NSIS 将正确显示它:

When i return the value with setuservariable(INST_0, server);, NSIS will be display it correctly:

你能告诉我，怎么了?我试图用 pluginapi-x86-ansi.lib 和 pluginapi-x86-unicode.lib 构建结果 .dll 但结果是一样的...

Can you tell me, whats wrong?I've tried to build the resulted .dll with pluginapi-x86-ansi.lib and pluginapi-x86-unicode.lib but the result is the same...

推荐答案

ANSI 字符解释为 Unicode (UTF-16LE) 倾向于中国人.

ANSI characters interpreted as Unicode (UTF-16LE) tends to look Chinese.

创建 Unicode 插件时，您需要:

When you create a Unicode plug-in you need to:

• 确保 UNICODE 和 _UNICODE 在您的项目/.C 文件中定义.
• 与 pluginapi-x86-unicode.lib 链接
• 将 Unicode True 添加到您的 .NSI
• 将插件放入\NSIS\x86-unicode

• Make sure UNICODE and _UNICODE is defined in your project/.C files.
• Link with pluginapi-x86-unicode.lib
• Add Unicode True to your .NSI
• Place the plug-in in \NSIS\x86-unicode

就您而言，您很可能忘记了 Unicode True.返回值是有效的，因为您实际上从未更改过 server 的内存，它仍然是相同的输入字符串.

In your case you most likely forgot about Unicode True. Returning the value works because you never actually changed the memory of server, it is still the same input string.
