为什么不成功？帮帮忙。(25分)

我在MSDN上找到有关资源替换的源代码，将它翻译成Delphi，但是无法成功。
不知道是哪里有问题？各位帮帮忙看看，谢谢了。
====Delphi============================================================
function MakeLangID(PrimaryLanguage,SubLanguage : word) : DWord;

下面是C的源代码：

BOOL result;
// Load the .EXE file that contains the dialog box you want to copy.
hExe = LoadLibrary("hand.exe");
if (hExe == NULL)
{
ErrorHandler("Could not load exe.");
}

// Locate the dialog box resource in the .EXE file.
hRes = FindResource(hExe, "AboutBox", RT_DIALOG);
if (hRes == NULL)
{
ErrorHandler("Could not locate dialog box.");
}

// Load the dialog box into global memory.
hResLoad = LoadResource(hExe, hRes);
if (hResLoad == NULL)
{
ErrorHandler("Could not load dialog box.");
}

// Lock the dialog box into global memory.
lpResLock = LockResource(hResLoad);
if (lpResLock == NULL)
{
ErrorHandler("Could not lock dialog box.");
}

// Open the file to which you want to add the dialog box resource.
hUpdateRes = BeginUpdateResource("foot.exe", FALSE);
if (hUpdateRes == NULL)
{
ErrorHandler("Could not open file for writing.");
}

// Add the dialog box resource to the update list.
result = UpdateResource(hUpdateRes, // update resource handle
RT_DIALOG, // change dialog box resource
"AboutBox", // dialog box name
MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), // neutral language
lpResLock, // ptr to resource info
SizeofResource(hExe, hRes)); // size of resource info.
if (result == FALSE)
{
ErrorHandler("Could not add resource.");
}

// Write changes to FOOT.EXE and then close it.
if (!EndUpdateResource(hUpdateRes, FALSE))
{
ErrorHandler("Could not write changes to file.");
}

// Clean up.
if (!FreeLibrary(hExe))
{
ErrorHandler("Could not free executable.");
}

What is the error code or error message!

varphone,没有错误信息，只是功能没有实现，无法替换图标

varphone，
程序执行到hUpdateRes:= BeginUpdateResource('d:/P.exe', FALSE);这一行，无法得到
正确的句柄。为什么？

What is your platform!
To use BeginUpdateResource() must in WinNT or Win2000 or WinXp!

varphone，
我用的是Windows Me。
那有没有别的办法实现我要的功能呢？

delphi与vc的资源保存方式是不同的，不知有没有关系！！？？
