把资源编译进EXE之（二）打造定制的资源编译器

之前分析了Qt Rcc 资源编译的实现，那么接下来就利用已有的代码，制作一个我们需要的资源编译器吧。

新建一个控制台工程，名为SimpleRcc，首先移植出关键函数：

void printAsciiHex(quint8 c,string& sOut){quint8 cc[5];cc[0] = '0';cc[1] = 'x';cc[2] = '0';cc[3] = '\0';cc[4] = '\0';if (c < 16) {cc[2] = (digits[c]);}else {cc[2] = (digits[c >> 4]);cc[3] = (digits[c & 0xf]);}static UInt64 iii = 0;//printf("%s,", cc);if (iii != 0)sOut += ",";sOut += (char*)cc;//strcat(pNewData,(char*)cc);if (iii % 16 == 0 && iii != 0){//printf("\n");//strcat(pNewData,"\r\n");sOut += "\n";}iii++;}

很明显，将char字符转为Ascii，然后保存进std::string中。

当然，这还不够，下面列出完整的代码，关键代码都有了，不再说细节：

// SimpleRcc.cpp : 定义控制台应用程序的入口点。#include "stdafx.h"#include <STDIO.H>#include <STDLIB.H>#include <string.h>#include <Shlwapi.h>#include <string>using namespace std;typedef signed char qint8;         /* 8 bit signed */typedef unsigned char quint8;      /* 8 bit unsigned */typedef __int64 Int64;typedef unsigned __int64 UInt64;const char * const digits = "0123456789abcdef";void printAsciiHex(quint8 c, string& sOut);int _tmain(int argc, _TCHAR* argv[]){printf("本程序将二进制文件或文本文件编译成16进制字节数组，以便静态编译到程序内部\n");char sInPutFileNames[500];printf("请输入要编译的文件名称:\n");scanf("%s", sInPutFileNames);char sCurrentDir[MAX_PATH];GetCurrentDirectoryA(MAX_PATH, sCurrentDir);strcat(sCurrentDir, "\\");strcat(sCurrentDir, sInPutFileNames);if (!PathFileExistsA(sCurrentDir)){printf("文件不存在\n");return 0;}FILE* fp = fopen(sCurrentDir, "rb");if (fp == NULL){printf("打开文件失败\n");return 0;}fseek(fp, SEEK_SET, SEEK_END);long iFileLen = ftell(fp);fseek(fp, SEEK_SET, SEEK_SET);char* data = new char[iFileLen];fread(data, 1, iFileLen, fp);fclose(fp);char sVarName[MAX_PATH];char delims[] = ".";char *result = NULL;result = strtok(sInPutFileNames, delims);while (result != NULL){strcpy(sVarName, result);break;result = strtok(NULL, delims);}string sOut = "unsigned long resource_data_";sOut += sVarName;sOut += "_length = ";char sDataLen[100];_itoa(iFileLen, sDataLen, 10);sOut += sDataLen;sOut += ";\r\nstatic const unsigned char resource_data_";sOut += sVarName;sOut += "[] = {\n";for (int i = 0; i<iFileLen; i++){printAsciiHex(data[i], sOut);}//printf("}\n");sOut += "\r\n};\r\n";char sOutFileName[MAX_PATH];strcpy(sOutFileName, sVarName);strcat(sOutFileName, "_out.cpp");FILE* fpNew = fopen(sOutFileName, "w");if (fpNew == NULL){printf("无法写入文件:%s\n", sOutFileName);goto POS_end;}fwrite(sOut.c_str(), 1, sOut.length(), fpNew);fclose(fpNew);POS_end:delete []data;printf("处理完成\n");return 0;}void printAsciiHex(quint8 c,string& sOut){quint8 cc[5];cc[0] = '0';cc[1] = 'x';cc[2] = '0';cc[3] = '\0';cc[4] = '\0';if (c < 16) {cc[2] = (digits[c]);}else {cc[2] = (digits[c >> 4]);cc[3] = (digits[c & 0xf]);}static UInt64 iii = 0;//printf("%s,", cc);if (iii != 0)sOut += ",";sOut += (char*)cc;//strcat(pNewData,(char*)cc);if (iii % 16 == 0 && iii != 0){//printf("\n");//strcat(pNewData,"\r\n");sOut += "\n";}iii++;}

我用VS2013编译通过，下面测试编译一个png图片到EXE中，

运行SimpleRcc.exe，输入11.png，则对应生成了一个11_out.cpp，

下面我用利用这个11_out.cpp，把png编译进exe中去。

新建控制台程序，把11_out.cpp添加到项目中，main.cpp代码如下：

#include <iostream>#include <windows.h>#include <string>#include "11_out.cpp"using namespace std;int main(){    printf("--begin\n");    printf("--resource_data_11_length:%d\n",resource_data_11_length);    FILE* fp = fopen("out.png","wb");    if(fp == NULL)    {        printf("open fail\n");        return 0;    }    fwrite(resource_data_11,1,resource_data_11_length,fp);    fclose(fp);    printf("--end\n");    return 0;}

运行生成的exe文件（main_bcc.exe），可以看到，一运行，便生成了out.png，打开此png一看，也是正确的。
