    <p>I am writing some javascript to be executed by the Windows Scripting Host, and I need to be able to read the shared file counts from the registry for certain specific DLLs. The registry key and values look like this:</p> <pre> [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls] "C:\\Program Files\\Common Files\\ACME Corp\\AcmeUtil.dll"=dword:00000002 "C:\\Program Files\\Common Files\\ACME Corp\\SuperEdit.ocx"=dword:00000001 </pre> <p>I am attempting to use the <a href="http://msdn.microsoft.com/en-us/library/x05fawxd(VS.85).aspx" rel="nofollow noreferrer">WshShell.RegRead</a> method to do this, but it doesn't seem to work. I think the problem is that this method only takes a single parameter which is the concatenated key path and value name for the value to be retrieved. Since the value name in this case is itself a path, the method thinks it is part of the key. Is there any way to get this method to recognize the value name for what it is?</p> <p>Here is the code that demonstrates the problem:</p> <pre> var shell = WScript.CreateObject("WScript.Shell"); var keyPath = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\SharedDlls\\"; var valName = "C:\\Program Files\\Common Files\\ACME Corp\\AcmeUtil.dll"; WScript.Echo("count = " + shell.RegRead(keyPath + valName)); </pre> <p>The error I am seeing is:</p> <pre>WshShell.RegRead: Invalid root in registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls\C:\Program Files\Common Files\ACME Corp\AcmeUtil.dll" </pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
