• .NET Development HttpFileXfer failure

  I haven't exhausted all options yet to find out why it is not working but decided to post this question anyway. I am playing with HttpFileXfer which is one of the projects in DeliverySmartClient as part of the directory HTTP Communication Sample which in turn is a part of .NET Compact Framework Samples that I downloaded from MS websites. I've got two computers with Win2K on each. I am the administrator on both. They are physically separated by about three city blocks. I am trying to run a C# sample not VB. I think I followed all the instructions of the readme file. I set up the virtual web directories recommended on both computers. ...Show All

• Software Development for Windows Vista Calling CreateProcessAsUser() from service

  According to some MS documents (e.g. http://www.microsoft.com/whdc/system/vista/services.mspx), it should be possible to use CreateProcessAsUser() API in a Vista service to create a process in user session. I am trying to achive this, but the function returns error code 1307 (ERROR_INVALID_OWNER) = "This security ID may not be assigned as the owner of this object." Does it work for somebody Many thanks in advance. The same code works for us on Vista as on XP, etc. The service is running as the Local System. 1. use WTSGetActiveConsoleSessionId to get the ID of the current active Windows session ...Show All

• Visual C++ ambiguous symbol

  Trying to compile a C++ WinForms Winsock related project with /clr option I get a few errors after adding #include <winsock2.h> statement. The reference is to a different header file: servprov.h . There is no direct reference in any of my files to this header. I verified it with quick find command. There is no reference to it in winsock2.h either. I do not know where the reference is coming from. Thus my first question is this: how come I get errors (8 total) from a header file that is not a part of my project explicitly. As far as I could determine, serprov.h is being referred via #include <servprov.h> in four other header ...Show All

• Visual Studio Problem with Class Designer and Pages and Controls

  I'm trying to create a class model for some pages and controls in my website.  However when I drag any of them to the class diagram I get an error "Some of the selected types cannot be added to the class diagram.  From a previous post there was a comment saying you cannot model these types. Is this still true, and if so does anyone know of a work around    I also tried reverse engineering to Visio, but the model only shows the true classes, again  not the pages or controls.  We used the reverse engineering alot in VS 2003 to show class diagrams, and the sequence diagrams for our more complex processes.
