• Visual Studio Express Editions System Volume Control

  Please can someone help me with Windows system volume! I have built an app that contains a slider control for which i would like to able to control Windows system volume from.  I have found some stuff on the net but it all seems to deal with the wave output instead of the volume control. I am coding in CSharp.  I thought these types of things were suppose to be easy in .net Thanks for any help in advance   Mark http://www.mp3car.com/vbulletin/archive/index.php/t-44148.html ...Show All

• Visual C# Overloading = operator

  Is it possible to use = operator to copy one object to another much like in C++ (using already created copy constructor), so if I write MyObject A = new MyObject(); MyObject B = A; A and B wouldn't point to same object but actually point to two different objects (that have the same state, but are infact different). I understand that it cannot be done OOTB because overload of = must be static method, but I'm interested is there any workaround solution that still allows usage of = operator. Thanks in advance! In C# (or .NET), you cannot overload assignment operators. I think this ...Show All

• Visual C++ using ATL macro to change LPSTR to LPCWSTR

  Hello, I'm making a 3D game and realized I would have to face many problems and maybe trying to "reinvent the wheel" on my own, if I wanted to implement SETTINGS -(for graphics mode) in my game. So I am going for DXUT framework or engine by Dx team or what it is called to simplify my life. But I am facing some problems, because it is using UNICODE and I need to change LPSTR to LPCWSTR so I use macro A2W(lpstr) and include this for it #include <AtlBase.h> #include <AtlConv.h> But then I have a compile error: fatal error C1189:#error : Need to include strsafe.h after tchar.h bec ...Show All

  In an EventHandlingScopeActivity, how can I do a finally block For example, what is the equivalent of this try { DoWork1(); DoWork2(); ... } catch (Exception1 ex1) { HandleEx1(); throw; } catch (Exception2 ex2) { HandleEx2(); throw; } finally { DoSomething(); } Thanks in advance We have no official "finally" solution OOB, though there is an easy, generic way to achieve it through a custom activity: Implement a custom activity that allows one activity as a child and one activity as a finally block.

• Visual Studio Express Editions High Speed Timers

  Hi I'm developping an Data Aquisition Program, to read a bunch of digital sensors. My problem: the main module, needs to read 32 sensors (I can read a byte at once, so It can be done in 4 steps) in a timebase of about 0,3 to 0,7 ms (miliseconds). Can it be done in VB.Net Express I already saw a post to a 10 ms timer, still ... it takes too long to read all the entries from the Digital Aquisition Board. Note: the Board is an Advantech PCI-1756 (32 I/O channels), and it has 2 entries that can generate an interrupt if 1 is present. Still, my problem is how to handle the information at such High Speed. Thank you for your time, and ...Show All

• Visual Studio Team System More on my question...Resolve Bugs automatically.

  Hi, How are Bugs added   I can run a test and add them manually by right-clicking on the test result and adding or associating the result with a Bug Work Item.  However, I would like to know whether Bugs are ever automatically added, and if so, how one can configure this process.  E.g. I see that MSF Agile comes with a few pre-added bugs - I suppose they were automatically added by the Build process. Bugs won't be added during ad hoc builds by the developer while s/he is developing, I suppose. Are they added automatically during a Team Build Are bugs ever automatically added, and if so, how Kind Regards ...Show All

• Software Development for Windows Vista Change delay Activity of State Machine Workflow dynamically

  Hi I have following problem. My state machine workflow contains a state in which three EventDriven activities are contained. One of them contains a DelayActivity, to escalated the Workflow if a certain amount of time is exceeded. I would like to disable the EventDriven Activity or the Delay activity. No matter which. I just want to disable the whole delay process. I would also like to enable it again, if certain properties get set in the meantime. So I would like to enable and disable a EventDrivenActivity (or the Delay Activity) during Runtime, because the information is not at hand before. I would also like to set the TimeoutDurat ...Show All
