    <p>I've run into a sticky problem using WMI (via win32com) in Python under Windows 7. I haven't been able to find a resolution for this.</p> <p>Here is my code:</p> <pre><code>from win32com.client import GetObject def get_printers(computer): """ Get a list of printers from the specified computer name. """ wmiservice = GetObject(r"winmgmts:{impersonationLevel=impersonate}!\\" + computer + r"\root\cimv2") return wmiservice.ExecQuery("Select * from Win32_Printer") for printer in get_printers("ps2"): print printer.Name </code></pre> <p>This works great under Windows XP. But fails miserably if I run this under Windows 7:</p> <pre><code>Traceback (most recent call last): File "C:\Python27\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 325, in RunScript exec codeObject in __main__.__dict__ File "C:\Python27\sample\temp2.py", line 8, in &lt;module&gt; for printer in get_printers("ps2"): File "C:\Python27\sample\temp2.py", line 5, in get_printers wmiservice = GetObject(r"winmgmts:{impersonationLevel=impersonate}!\\" + computer + r"\root\cimv2") File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 72, in GetObject return Moniker(Pathname, clsctx) File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 87, in Moniker moniker, i, bindCtx = pythoncom.MkParseDisplayName(Pathname) com_error: (-2147024891, 'Access is denied.', None, None) </code></pre> <p>I tried everything I can think of in Win 7: disabled firewall (no virus scanner), ensured DCOM is enabled, ensured WMI is enabled, and disabled UAC. Any help would be greately appreciated.</p> <p>Note: I'm using Python 2.7.1 with pywin32 build 215, under Windows 7 Ultimate x86 (and Windows XP SP3).</p>

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.
