I've seen that by specifying a '/e' on the command line of regedit.exe that it export the entire HKEY_LOCAL_MACHINE to a text file you specify.  Is it possible to export only part of the key to a file?  If so, how?

I should have been more specific.  I'm trying to do this without user interaction, from a C++ program.

When you have to write small WIN32 program. Enumerate all registry keys in selected branch ( from command line) and write it to file.

I know how to do this with a recurvise scan & write, and I've even done this, but it has some limitation.  For example there are a dozen or so different types of registry keys:
   Binary
   ResourceList
   ResourceDecriptor
   ResourceRequirmentsList
   multipleString
   UnexpandedString
   DoubleWord
   String
   DoubleWordBigEndian
   SymbolicLink
   None
   and possibly more to come.

I have only found the format of serveral of these, but not all.
Unless I can be sure that I cover ALL CASES, I would rather use regedit, which is 100% guarentied to work, assuming that I can custom tailor the branch to be exported.

Below is the text copied from WIndows95 Resource Kit:

regedit [/L:system] [/R:user] file1.reg, file1a.reg...
regedit [/L:system] [/R:user] /e file3.reg [regkey]
regedit [/L:system] [/R:user] /c file2.reg

Parameter      Description
/L:system      Specifies the location of SYSTEM.DAT.
/R:user      Specifies the location of USER.DAT.
file1.reg      Specifies one or more .REG files to import into the Registry.
/e file3.reg      Specifies the filename to which the Registry should be exported.
regkey      Optionally, specifies the starting Registry key from which to export a portion of the Registry. If no value is specified, regedit /e exports the entire Registry.
/c file2.reg      Specifies the .REG file to use to replace the entire contents of the Registry.
Caution  Use the regedit /c option with extreme care, and only when you are sure that the specified .REG file contains a complete image of the Registry.

Here's my example:

regedit /e "c:\program files\1.reg" "HKEY_CURRENT_USER\Software\Microsoft\Microsoft Help Workshop"

Thank you!  I thought I had already tried that combination, but I guess not...
