Flash multi open

some flash Call after the user logs in  SharedObject.getLocal("browserSO");

Put the user KEY Save information to file  browserSO.sol

And keep reading  browserSO.sol file , According to the read KEY And stored in memory after login KEY Compare ,

If it's not the same , It means that the user has opened more , here flash Will automatically exit ....

I know why , See how to solve it

The first thing that comes to mind HOOK CreateFileW Replace file path , In this way, each process saves and reads different files , You can drive more

Do as you say , After replacing the file path , I can't find out ,TrueCreateFileW Calls always return failures , Unknown cause ...

So replacing the file path doesn't work , Then try another way ：

1、HOOK CreateFileW preservation browserSO.sol The handle of

2、HOOK WriteFile Write browserSO.sol Save a copy of the data

3、HOOK ReadFile Back in the HOOK WriteFile The saved browserSO.sol data

This will ensure that each flash Each process reads its own browserSO.sol The file , That is, you can open more ...

The main codes are as follows ：

HANDLE WINAPI MyCreateFileW(
	LPCWSTR lpFileName, 
	DWORD dwDesiredAccess, 
	DWORD dwShareMode, 
	LPSECURITY_ATTRIBUTES lpSecurityAttributes, 
	DWORD dwCreationDisposition, 
	DWORD dwFlagsAndAttributes, 
	HANDLE hTemplateFile)
{
	HANDLE hRet = TrueCreateFileW(
		lpFileName,
		dwDesiredAccess,
		dwShareMode,
		lpSecurityAttributes,
		dwCreationDisposition,
		dwFlagsAndAttributes,
		hTemplateFile);
	

	// flash More open 
	// SharedObject.getLocal("browserSO");
	//  I wanted to replace lpFileName The path of 
	//  Replace lpFileName After the path of , Discovery call TrueCreateFileW Always fail ,
	//  Error code ：3  The system could not find the specified path   The actual path exists , Compare the files you created manually 
	//  Therefore, we can only save the country by curving  
	// 1、 preservation browserSO.sol Handle to the file 
	// 2、WriteFile Copy a copy of data when 
	// 3、ReadFile Shi Ba Zai WriteFile The data copied in is returned to Flash that will do 
	//  namely Flash Write what data   Return the written data when reading data   In this way, you can open more 
	if (wcsstr(lpFileName, L"browserSO.sol") != NULL)
	{
		gBrowserSO = hRet;
		//OutputDebugStringA("MyCreateFileW");
	}

	return hRet;
}

BOOL WINAPI MyWriteFile(
	HANDLE hFile, 
	LPCVOID lpBuffer, 
	DWORD nNumberOfBytesToWrite, 
	LPDWORD lpNumberOfBytesWritten, 
	LPOVERLAPPED lpOverlapped)
{
	if (hFile == gBrowserSO)
	{
		/*char szLog[1024] = { 0 };
		sprintf(szLog, "hook MyWriteFile nNumberOfBytesToWrite=%d", nNumberOfBytesToWrite);
		OutputDebugStringA(szLog);*/

		memcpy(gDataBrowserSO, lpBuffer, nNumberOfBytesToWrite);
		gDataBrowserSOLen = nNumberOfBytesToWrite;
	}

	return TrueWriteFile(hFile, lpBuffer, nNumberOfBytesToWrite, lpNumberOfBytesWritten, lpOverlapped);
}

BOOL WINAPI MyReadFile(
	HANDLE hFile, 
	LPVOID lpBuffer, 
	DWORD nNumberOfBytesToRead, 
	LPDWORD lpNumberOfBytesRead, 
	LPOVERLAPPED lpOverlapped)

	{

		sprintf(szLog, "hook MyReadFile nNumberOfBytesToRead=%d", nNumberOfBytesToRead);
		OutputDebugStringA(szLog);*/

		memcpy(lpBuffer, gDataBrowserSO, gDataBrowserSOLen);
		if (lpNumberOfBytesRead != NULL)
		{

		return TRUE;
	}
