How to get the signer's company name from a memory signed file data?

[EDN Admin]

I use the CryptQueryObject function to get <span lang="EN-US" style="font-size:10.5pt; font-family:Calibri,sans-serif HCRYPTMSG*
<span lang="EN-US" style="font-size:10.5pt; font-family:Calibri,sans-serif phMsg.
The dwObjectType is CERT_QUERY_OBJECT_BLOB and the pvObject is a CERT_BLOB<span lang="EN-US" style="font-size:10.5pt; font-family:Calibri,sans-serif (set the memory data point and size) pointer.It can work
<span id="x_result_box" lang="en <span>in windows7, but has problem in Vista. In Vista, it will return 0x80092009 error code(<span lang="EN-US" style="font-size:10.5pt; font-family:Calibri,sans-serif "cannot find the requested object").

Any suggestions? thanks all.
