Question

我正在尝试设置exe文件的图标。我在网上搜索了很多，但找不到任何有效的方法。我到目前为止找到的代码：

#include <io.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <windows.h>

#pragma pack(push, 2)
typedef struct {
    WORD Reserved1;       // reserved, must be 0
    WORD ResourceType;    // type is 1 for icons
    WORD ImageCount;      // number of icons in structure (1)
    BYTE Width;           // icon width (32)
    BYTE Height;          // icon height (32)
    BYTE Colors;          // colors (0 means more than 8 bits per pixel)
    BYTE Reserved2;       // reserved, must be 0
    WORD Planes;          // color planes
    WORD BitsPerPixel;    // bit depth
    DWORD ImageSize;      // size of structure
    WORD ResourceID;      // resource ID
} GROUPICON;
#pragma pack(pop)

void InjectMainIcon(LPCWSTR Where, LPCSTR What)
{
   HANDLE hWhere = BeginUpdateResource(Where, FALSE);

   char *buffer;    // buffer to store raw icon data
   long buffersize; // length of buffer
   int hFile;       // file handle

   hFile = open(What, O_RDONLY | O_BINARY);
   if (hFile == -1)
      return; // if file doesn't exist, can't be opened etc. 

   // calculate buffer length and load file into buffer
   buffersize = filelength(hFile);
   buffer = (char *)malloc(buffersize);
   read(hFile, buffer, buffersize);
   close(hFile);

   UpdateResource(
      hWhere,  // Handle to executable
      RT_ICON, // Resource type - icon
      MAKEINTRESOURCE(1), // Make the id 1
      MAKELANGID(LANG_ENGLISH, 
                 SUBLANG_DEFAULT), // Default language
      (buffer+22), 
      // skip the first 22 bytes because this is the 
      // icon header&directory entry (if the file 
      // contains multiple images the directory entries
      // will be larger than 22 bytes
      buffersize-22  // length of buffer
     );


   // Again, we use this structure for educational purposes.
   // The icon header and directory entries can be read from 
   // the file.
   GROUPICON grData;

   // This is the header
   grData.Reserved1 = 0;     // reserved, must be 0
   grData.ResourceType = 1;  // type is 1 for icons
   grData.ImageCount = 1;    // number of icons in structure (1)

   // This is the directory entry
   grData.Width = 32;        // icon width (32)
   grData.Height = 32;       // icon height (32)
   grData.Colors = 0;        // colors (256)
   grData.Reserved2 = 0;     // reserved, must be 0
   grData.Planes = 2;        // color planes
   grData.BitsPerPixel = 32; // bit depth
   grData.ImageSize = buffersize - 22; // size of image
   grData.ResourceID = 1;       // resource ID is 1

   UpdateResource(
      hWhere,
      RT_GROUP_ICON,
      // RT_GROUP_ICON resources contain information
      // about stored icons
      L"MAINICON",
      // MAINICON contains information about the
      // application's displayed icon
      MAKELANGID(LANG_ENGLISH, SUBLANG_DEFAULT),
      &grData,
      // Pointer to this structure
      sizeof(GROUPICON)
     );

   delete buffer; // free memory

   // Perform the update, don't discard changes
   EndUpdateResource(hWhere, FALSE);
}

它不会在文件资源管理器中显示图标，因此它不起作用。

当我在Resource hacker中打开exe文件时，只有1个图标资源： Picture

奇怪的是，当我从Resource Hacker手动更改图标时，有8个图标资源：Picture 2

任何帮助将不胜感激。我被困了2-3个小时

像C ++中的Resource Hacker一样，以编程方式更改可执行文件的图标
