how to use a resource file (txt - tab delimited) as a data source for win32 application
提问by coder
i am working on a win32 app. i am currently using the text file which has tab delimited data as a source. i want to embed this as a resource so that i need not worry about shipping this file along with .exe file.
我正在开发一个 win32 应用程序。我目前正在使用具有制表符分隔数据的文本文件作为源。我想将此作为资源嵌入，这样我就不必担心将此文件与 .exe 文件一起传送。
can anyone tell me how to do it?
谁能告诉我怎么做？

Windows binary can have resources embedded in them. Most resources are of predetermined type (e.g. a menu, an icon or a bitmap) but you can also embed arbitrary binary data (e.g. a text file). The proper syntax is hard to figure out just from reading msdn docs.
Windows 二进制文件中可以嵌入资源。大多数资源都是预先确定的类型（例如菜单、图标或位图），但您也可以嵌入任意二进制数据（例如文本文件）。仅通过阅读 msdn 文档很难找出正确的语法。
This snippet shows how to embed a binary resource from a file.
此代码段展示了如何从文件中嵌入二进制资源。
First you need to define a resource identifier in a header file (e.g. resource.h) that will be used by both C compiler and resource compiler:
首先，您需要在 C 编译器和资源编译器都使用的头文件（例如，resource.h）中定义一个资源标识符：
#define MY_RESOURCE 300
Then you need to add to your resource file (e.g. resource.rc):
然后你需要添加到你的资源文件（例如resource.rc）中：
MY_RESOURCE RCDATA "file-with-data.txt"
And finally, this is how you can get to this data:
最后，这是获取这些数据的方法：
void WorkOnResource(void)
{
HGLOBAL res_handle = NULL;
HRSRC res;
char * res_data;
DWORD res_size;
// NOTE: providing g_hInstance is important, NULL might not work
res = FindResource(g_hInstance, MAKEINTRESOURCE(MY_RESOURCE), RT_RCDATA);
if (!res)
return;
res_handle = LoadResource(NULL, res);
if (!res_handle)
return;
res_data = (char*)LockResource(res_handle);
res_size = SizeofResource(NULL, res);
/* you can now use the resource data */
}

Define the resource ID, add this to the .rc file:
定义资源 ID，将其添加到 .rc 文件中：
ID_CUSTOM1 ANYTHINGGOESHERE "filename.txt"
Read it at runtime with code like this:
在运行时使用如下代码读取它：
HRSRC hRes = FindResource(hInst, MAKEINTRESOURCE(ID_CUSTOM1), L"ANYTHINGGOESHERE");
HGLOBAL hMem = LoadResource(hInst, hRes);
DWORD size = SizeofResource(hInst, hRes);
char* resText = (char*)LockResource(hMem);
char* text = (char*)malloc(size + 1);
memcpy(text, resText, size);
text[size] = 0;
FreeResource(hMem);
// use text...

why not use a header file and put all your data in a static array. That way you don't have to parse a text file or worry about deployment
为什么不使用头文件并将所有数据放在静态数组中。这样您就不必解析文本文件或担心部署

If you are looking for the "correct" way to do this then I would suggest adding your text file as a resource (as a string table or binary) and using LoadString or FindResource to access it.
如果您正在寻找执行此操作的“正确”方法，那么我建议将您的文本文件添加为资源（作为字符串表或二进制文件）并使用 LoadString 或 FindResource 来访问它。

in Visual Studio, you can add text as a resource just like any other resource.
在 Visual Studio 中，您可以像添加任何其他资源一样将文本添加为资源。
In the resource.rc file of your project:
在项目的 resource.rc 文件中：
IDR_MYRESOURCE MYCUSTOMRESOURCETYPE "path_to_file.txt"
in the resource.h file:
在 resource.h 文件中：
#define IDR_MYRESOURCE 104
(or you can add these through the resource editor by selecting "Add Resource", then "New")
（或者您可以通过资源编辑器通过选择“添加资源”，然后“新建”来添加这些）
To load the resource in code:
在代码中加载资源：
HRSRC hRes = FindResource( 0, "#104", "MYCUSTOMRESOURCETYPE" );
HGLOBAL hData = LoadResource( 0, hRes );
LPVOID data = LockResource( hData );
Now data points to the text, and can be casted to string.
现在数据指向文本，并且可以转换为字符串。
