The SPS WeblogMicrosoft Programming TechnologiesPE Files, UAC, Reg-Free COM, and Other Crazy Stuff - Part 5- September 28, 2007 Access Tokens The MSDN describes an access token as follows: "An access token contains the security information for a logon session. The system creates an access token when a user logs on, and every process executed on behalf of the user has a copy of the token. The token identifies the user, the user's groups, and the user's privileges. The system uses the token to control access to securable objects and to control the ability of the user to perform various system-related operations on the..http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,7da838af-e7e1-45a9-a474-e7f8a339... PE Files, UAC, Reg-Free COM, and Other Crazy Stuff - Part 4- September 25, 2007 COM Elevation The code at the bottom of this blog post provides a Function called CreateObjectElevated which is provided as a compliment to Visual FoxPro's CreateObject, CreateObjectEx, and NewObject functions. What it does that those other 3 functions can't do is provide for COM elevation. Basically COM elevation provides the ability for an application running under a limited user account (LUA) to instantiate a COM class (OLEPublic) that requires a higher level of permissions in order to do..http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,0d08c7d7-5d50-4b3e-9fcd-e1097534... PE Files, UAC, Reg-Free COM, and Other Crazy Stuff - Part 3- September 25, 2007 Getting Typelib Information In Part 2 of this series some of you may have wondered how it was that you only had to send in the name of the COM server and all of the OLEPublic classes as well as their progids and clsids would be added to the application manifest XML. Well, that was facilitated by using the TLI.TypeLibInfo class (part of the typinf32.dll). I thought it might be useful to post a short blog entry that gave you some code so that you could explore this object and what it provides...http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,80565cb6-4b46-4dd0-b203-1f28987c... PE Files, UAC, Reg-Free COM, and Other Crazy Stuff - Part 2- September 25, 2007 Last Time In part 1 of this series I covered generally what I am going to show and also gave some brief information regarding the PE format. At the end I provided some code that would allow a Visual FoxPro developer to step through some of the PE structures and data. In this blog entry I'm going to show you how you can edit the application manifest in a PE File and how that can facilitate elevated execution permissions in Vista UAC and Reg-Free COM. Application Manifests in Visual...http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,a7469c56-d058-41cd-b345-82a8121e... PE Files, UAC, Reg-Free COM, and Other Crazy Stuff - Part 1- September 25, 2007 I Feel Your Pain In an August 14th blog posting, Lisa Slater Nicholls bemoans the fact that the Vista Toolkit portion of Sedna doesn't include any Vista User Account Control stuff. To that I say, "I couldn't agree with you more Lisa!". Now, as many of you know I am the developer that has been doing the work for Microsoft on the Vista Toolkit. While I would like you to try and remember that I didn't set the priorities for the Vista Toolkit or make the final decisions about what was in or out of.http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,e7782545-c3cc-4b78-9005-ce769669... VFPCompression Update - Fixes, UNC Pathing, and Callbacks- September 6, 2007 VFPCompression Update This update contains numerous fixes (unfortunately I didn't keep track, I just fixed anything and everything anyone mentioned to me). The library now allows the use of UNC paths, and it also contains a new callbackevent feature that allows a user-defined functionproceduremethod to be hooked into the Zip and Unzip routines. In so doing the developer can monitor open, close, and even the number of bytes being read or written as the zip functions are called (see...http://www.sweetpotatosoftware.com/SPSBlog/PermaLink,guid,07ed8874-8781-4e76-878b-92b3f4cf... |
