怎么看都看不懂TRegistry::ReadString(const AnsiString Name)里面的Name的作用.

[wenminghu]

Retrieves a string value from a specified data value associated with the current key.

AnsiString __fastcall ReadString(const AnsiString Name);

Description

Call ReadString to read a string value from a specified data value associated with the current key. Name is the name of the data value to read.

If there is no Registry entry with the specified name, ReadString returns an empty string. If the Registry entry contains something other than a string, an exception is thrown.

Note: ReadString retrieves data stored by either the WriteString or WriteExpandString method.

这段代码又是什么意思呢?

TRegistry *pRegistry = new TRegistry;
pRegistry->RootKey = HKEY_CLASSES_ROOT;

try
{
pRegistry->OpenKeyReadOnly(strFileExtName);
AnsiString strFileType = pRegistry->ReadString("");
pRegistry->CloseKey();
pRegistry->OpenKeyReadOnly(strFileType + "\\DefaultIcon");
strDefaultIcon = Registry->ReadString("").Trim();
pRegistry->CloseKey();
pRegistry->OpenKeyReadOnly(strFileType + "\\shell\\open\\command");
strOpenProgram = pRegistry->ReadString("").Trim();
}
catch(...)
{
}
__finally
{
delete pRegistry;
pRegistry = 0;
}

Name是键的名称。
