• Visual Basic What is the difference between OCXs and DLLs ?

  Hello, I wanted to add Windows Media Player to my application but when adding reference to the project, I found there was two Windows Media Player controls : WMP.DLL and MSDXM.OCX. I am currently using the DLL but I would like to know what is the difference between the two controls as they seem to be the same. Is there anyone to be preferred Thank you Oh okay, I remember these was coding differences but I couldn't tell. But are there any differences when compiling, like does the app will need runtime files or is it managed (automatic) Thanks. ...Show All

Kaos wrote: I want to add days to a date, but I dont want to count the saturdays or sundays, or party days, how can I do that Thanks for all the help. As Stephen says, there's nothing intrinsic in the framework or the Base Class Library to do what you want. But, it's already been done many times. For example: Calculate Number of Working Days . ...Show All

• .NET Development Modify System.Exception in SetILFunctionBody

  I am wondering if I can get some help on this. We have working "Proxy" that is invoked via insertion into methods and gathers all the calling arguments, etc. and passes to a handler. We are using the SetILFunctionBody during JIT compilation. It works fine for 1.1, but in 2.0 ONLY works when using LoaderOptimization other than SingleHost when hooking corlib methods such as the System.Exception .ctor. We are hooking many methods - all NON core methods work well. I have come to the conclusion that it has to do with Domain Neutrality of mscorlib (only) being in the shared domain. So, my questions are this: Other than the LoaderOptimizationAttribute OR the args to the CorRuntimeBindEx to load the CLR - how can one override the Loade ...Show All

• SQL Server Closing a conversation later on and Microsoft Service Broker Interface (sample)

  In a messaging application, a client sends a message to the server. The server uses Service Broker Interface, and is CLR based. On the server, the message has a life cycle - going throughout multiple transitions until is final (Pending, In Transit, Delivered, TimedOut, Undeliverable). As the server receives the message, it sends back to the client a reply status message of In Transit. It does so using the same message’s conversation. It also saves – along with the message – its conversation handle. The dialog is not closed. After a while, the server may decide that the message has gotten to a final state (Delivered or TimedOut). I would like at that time to send a reply status message (Final State) back to the client and also close th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Could C# be the future of gaming?

  Since XNA is using C#, and is is a more intuitive language than C++, is it possible that in the future that C# will dominate, espessially in AAA titles. Could XNA be ushering a new way of programming in the main stream Hi Jeff, As some one who is a partner in a company (and lead developer) that produces enterprise high performance security applications, many of them in C#, I think you will be very surprised what you can do with C#. I develop in C++, C++/CLI (.net C++) and C#. C# is my favorite by far. While it certainly takes a lot of care and research to get the "barn burning" speed you can truly get out of C#. Once you know what to avoid and how to write performance critical apps in C#, you will only go back when you ...Show All

• Windows Forms Hey Moderator

  Anybody know how to set up a gridview so that each column header has an up and down arrow that when clicked would sort that column in that direction I have seen tons of examples of a single image to indicate which direction the current column is being sorted on, but why do that and possibly have to click a column header twice to sort in the desired direction when you can just have an up and down arrow image for each column that reacts to the click event by sorting in that direction It's nice that you have a data controls section, but this topic is not about windows based programming, it is about ASP.Net applications in C# ...Show All

• Smart Device Development Cab installation failures due to signed files

  Hi. I have a Smart Device CAB file targeted for WM5 Smartphone. I'm using Visual Studio 2005 to build it. For my executables/dlls, I'm signing the files using the SDK developer certificate. When I'm installing on an actual phone or on the emulator, I will sometimes get errors on the signed files. Usually, they happen on the same files but not on all the signed files. I think it is more likely to happen on a file that self-registers. The problem goes away when I reinstall with a rebuilt file that is not signed. In setup.log under \Application Data\Volatile, I will get something like this: <characteristic type="fsbraille.dll" translation="install"> <characteristic-error type="Extract"> <pa ...Show All
