在Embarcadero RAD Studio XE中使用Visual Studio DLL吗? [英] Using Visual Studio DLL in Embarcadero RAD Studio XE?

问题描述

我打算在Embarcadero RAD Studio XE的VCL Form C ++项目中添加拼写检查器功能.

I'm intending to add a spellchecker feature into a VCL Form C++ project in Embarcadero RAD Studio XE.

到目前为止，按照

So far, I succeeded in creating an application that uses hunspell in Visual Studio 2012 following the steps in C++ - Using HunSpell 1.3.2 with Visual Studio 2010. Therefore my first approach was to reuse the .dll created with the VS compiler in RAD Studio.

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;


// dll path
const wchar_t* library = L"libhunspell.dll";

//  hunspell constructor
extern "C" __declspec(dllimport) hunspell_initialize(char const * aff,char const * dic);

//adds a word to the loaded dictionary
extern "C" __declspec(dllimport) int add(char const *) ;


//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
    : TForm(Owner)
{
    HINSTANCE load;
    try
    { load = LoadLibrary(library); }
    catch(Exception &e)
    { ShowMessage(e.Message); }
    if (load)
    {
        ShowMessage("Library Loaded!");

        hunspell_initialize("de_DE.aff","de_DE.dic");
        add("myword");
    }
    else {ShowMessage ("Library hasn't loaded!");}



}

我可以加载库，但是链接器无法解析外部函数.

I can load the library, however the linker is unable to resolve the external functions.

我的第二种方法是导入hunspell源代码并包含"hunspell.hxx".但是我在文件"csuitl.hxx"中得到了声明语法错误

My second approach was to import the hunspell source code and include "hunspell.hxx". However I get a declaration syntax error in the file "csuitl.hxx"

代码段:

// default flags
#define DEFAULTFLAGS   65510
#define FORBIDDENWORD  65510
#define ONLYUPCASEFLAG 65511

// fopen or optional _wfopen to fix long pathname problem of WIN32
LIBHUNSPELL_DLL_EXPORTED FILE * myfopen(const char * path, const char * mode); // << error line

// convert UTF-16 characters to UTF-8
LIBHUNSPELL_DLL_EXPORTED char * u16_u8(char * dest, int size, const w_char * src, int srclen);

// convert UTF-8 characters to UTF-16
LIBHUNSPELL_DLL_EXPORTED int u8_u16(w_char * dest, int size, const char * src);

我想知道，是否缺少将hunspell包含到我的项目中的简单方法，因为它是一种广泛使用的工具.任何帮助表示赞赏:)

I'm wondering, if I'm missing a simple way to include hunspell into my project since it's a widely used tool. Any help is appreciated :)

推荐答案

好吧，如果有人尝试在Embarcadero RAD Studio XE中使用hunspell，或者通常想知道如何使用Embarcadero内部由Visual Studio创建的DLLRAD Studio XE，我终于找到了解决方案.

Well, if anyone ever tries to use hunspell in Embarcadero RAD Studio XE, or generally wants to know how to use a DLL that was created by Visual Studio inside Embarcadero RAD Studio XE, I finally found a solution.

命令行提示符:

implib -a hunspell.lib hunspell.dll

创建一个LIB文件，该文件可以添加到项目中.要查找功能原型，可以通过以下方式创建文本文件:

creates a LIB file which can be added to the project. To look up function prototypes, you can create a text file by:

tdump -ee -m hunspell.dll > out.txt

最后，可以通过以下方式导入功能:

Finally, functions can be imported by:

extern "C" __declspec(dllimport) [return type] [function name] ([function parameters]);
