• Smart Device Development Compact framework version of: [ClassInterface(ClassInterfaceType.AutoDual)]

  What's the compact framework version of [ ClassInterface ( ClassInterfaceType .AutoDual)]. I'm trying to port this http://www.codeproject.com/cs/miscctrl/exposingdotnetcontrols.asp df=100&forumid=2373&exp=0&select=1359005 to the compact framework 2.0. Well .Net Compact Framework doesn't support class interfaces (we only support the 'None' option in that enumeration). To get the equivalent behavior you would need to define an interface exposed to COM that has all the public methods and properties of your class and then make your object implement that interface. Of course thats missing ...Show All

• Windows Forms Profiles failing to update a Click Once application

  The scenario: We have a Click Once application deployed to 70+ machines. This deployment site has been active since mid November 2005. There are multiple profiles on these machines totaling easily 140 profiles. There are profiles on each machine that are used more often than others. We push patches to the deployment site regularly, sometimes multiple patches in a day. The application checks on startup for patches. Typically a profile is logged in once a day. So the possibility exists that a profile may be logged in while multiple patches are pushed. The problem: Recently it was determined that three profiles, two on o ...Show All

• Visual C++ VS2005 Linker /ENTRY

  We have a bunch of legacy DLL code which uses makefiles to build. The DLLs all use /ENTRY:SomeOtherName rather than the default and I've encountered a problem in VS2005. If I put the /ENTRY switch on the linker command line in the makefile, it doesn't seem to work - when I attempt to load the DLL via LoadLibraryEx(), I get an entry point not found error (0x7f). If, however, I put the /ENTRY switch in the LINK environment variable, the DLL loads without problems. What's up with that I believe the LINK environment variable gets added at the start of the linker command. Could it be that you are addin ...Show All
