• Visual C++ search for value not greater than another in a jagged array of structures

  I was tinkering with the idea of a class that had a reversible memory value array, and its first incarnation was to have for each "location" an array of structures that had values clock k and value v. Is there a way to adapt an array binary search to look at a structure value k which is stored sorted or do I really need to write my own alg for this in function readx: #define AML 0x100 #pragma once ref struct md { unsigned int v ; unsigned long k ;}; ref class rvd { public : rvd( void ); public : unsigned long inc_ks( unsigned int ); public : void dm( unsigned long k0); public : unsigned int readx( int loc, unsigned long k0); public : unsigned int read ...Show All

• Visual Studio 2008 (Pre-release) My MembershipProvider + ReliableSession issue

  I have a service that uses UsernameAuthentication with a MembershipProvider and it also has ReliableSession enabled and OrderedDelivery = true (I’m not sure if OrderedDelivery has anything to do with my problem).   When a valid username/password is sent then everything works great.   The problem is that whenever an INVALID username/password is sent in the message the ValidateUser method in the custom MembershipProvider gets called repeatedly until the clients SendTimout expires, at which time the MessageSecurityException is thrown by the service proxy.   If I disable ReliableSession and then send the invalid username/password in the message then the MessageSecurityException gets thrown immediately by the service proxy as I’ ...Show All

• Visual Basic Refresh the Winows OS from within Visual Basic

  I've made some program in Visual Basic 2005 that works with changing files and folders. After I've finished it, the main problem is to refresh the Windows OS.

• Visual Studio New MPLex and MPPG tools in latest VSIP SDK

  First of all, thank you for finally integrating these important tools into the MPF world. I can finally (hopefully) bring my language tools out of the unmanaged world. I'm running into a few issues, and I couldn't find any documentation on them in the help files. First is that mppg doesn't seem to create an output file, it just spews text to the console. It could be that it is failing silently before it gets to the point where it is supposed to create a file. If I do mppg parser.y > parser.cs, then it spits out a mostly complete cs file. I'm not sure if that is supposed to work that way or not, but MPLex seems to spit out a file without the need for output redirection. So if I bring my parser.cs file into VS, and after I found the ...Show All
