我为我的应用程序编写了一个C ++安装程序引导程序(硬盘要求,因为我需要完全控制文件的格式)。现在我想弄清楚如何以最少的开销将我的MSI嵌入到我的引导程序EXE中。我的所有搜索都向我显示了反向(如何在MSI中嵌入EXE)。
此安装程序必须脱机工作,因此我无法让我的引导程序只下载该文件。
我当然可以将它作为字节流嵌入到我的源文件中,但这会对文件大小造成大量开销。

将数据作为资源嵌入二进制文件并将其解压缩是相当常见的。这种事情:

以下是如何提取数据的示例。
#include "stdafx.h"
#include "resource.h"
#include <iostream>
#include <fstream>
#include <iterator>
#include <vector>
#include <Windows.h>
#include <shellapi.h>
using namespace std;
void extract_bin_resource(std::wstring strCustomResName, int nResourceId, std::string strOutputPath)
{
HGLOBAL hResourceLoaded; // handle to loaded resource
HRSRC hRes; // handle/ptr to res. info.
char *lpResLock; // pointer to resource data
DWORD dwSizeRes;
std::string strOutputLocation;
std::string strAppLocation;
hRes = FindResource(NULL, MAKEINTRESOURCE(nResourceId), strCustomResName.c_str());
hResourceLoaded = LoadResource(NULL, hRes);
lpResLock = (char *)LockResource(hResourceLoaded);
dwSizeRes = SizeofResource(NULL, hRes);
std::ofstream outputFile(strOutputPath.c_str(), std::ios::binary);
outputFile.write((const char *)lpResLock, dwSizeRes);
outputFile.close();
}
int CALLBACK WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
// Extract the bundled installer
extract_bin_resource(L"MSI", IDR_MSI1, "installer.msi");
// Execute the installer
SHELLEXECUTEINFO ShExecInfo = { 0 };
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = L"msiexec.exe";
ShExecInfo.lpParameters = L"/i installer.msi";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess, INFINITE);
// Delete the installer
DeleteFile(L"installer.msi");
return 0;
}
