• Visual C# Constructor on type 'MYCLASS' not found.

  I have 7 classes.. Some of them inherited from non serializable object , some of other inherited from 3rd party components. All of my classes have got [Serializable] attribute , ISerilazable interface and ClassName( SerializationInfo info, StreamingContext context) Most of them have got List of the other as property . Altough everything fine I got error like that " Constructor on type 'myclass' not found." I couldnt understand why Thx for advices.. I think that when you iterate through the types via reflection each type must implement a default constructor (without parameters). Stay cheerful, Dave ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed Direct3D 10

  Since XNA only supports DirectX 9.0 Where is Managed Direct3D 10 I hope there will be Managed wrapper for Direct3D 10 thanks Michael, it’s good to have an official word about managed Direct3D 10. As I have written before something with official support from Microsoft will always better than my own one man show. But as long as you don’t write a fully managed runtime that talk direct to the driver (I thought about this too) I believe you couldn’t be much faster than my wrapper. Maybe if you have access to a better C++/CLR compiler that allows you to use less expensive managed to unmanaged calls. If the last rumors are true the D3D10 hardware problem should be solved in the next f ...Show All

• Visual Studio Team System Using VSS in VB6 After Installing MSSCCI for TFS

  This afternoon I installed MSSCCI for TFS so that I could begin using Team Foundation Server with VB6. Now when I open an old project that is maintained using Visual SourceSafe VB6 seems to be trying to use TFS instead of VSS for that project's source control. Is there a way to have access to both in VB6 or at least can I get VSS back long enough to convert the old projects Thank you for your help in advance. Jeff Q It did help! Thank you for responding so quickly. I put the commands in the blog you sent me to in a couple of command files on my desktop and it is now easy to switch back and forth!

• Windows Forms How to find the handle for SendMessage(windowHandle, WM_RBUTTONDOWN, 0, 0);

  I'm trying to simulate a right click on the window that is currently active. I can get the following code to work using windows forms by declaring the handle as this.handle or textbox1.handle SendMessage(this.handle, WM_RBUTTONDOWN, 0, 0); SendMessage(textbox1.handle, WM_RBUTTONDOWN, 0, 0); I've also tried using IntPtr windowHandle = FindWindow(null, _windowName); to obtain the handle of a specific handle but this does not work either. What I'm attempting to do..... 1.) Run a windows form app 2.) Click a button which instantiates a timer class which executes the SendMessage function listed above. 3.) Make an applications (notepad for instance) and execute a right click in Notepad. Any ideas on what I'm doing wrong to obtain or execute t ...Show All

• Windows Forms Can ObjectDataSource attributes be used in Winform?

  Hello, I have developed a Data access Layer for my project. I have read how to create a layer using the ObjectDataSource Attributes. Now every article I have read have shown ObjectDataSource Attributes being used in Asp 2.0. Can I use them in Winform in anyway It is a bit confusing. The SqlDataSource and ObjectDataSource are used by Asp.Net. Instead in Winforms you use a BindingSource and Databinding; however you can bind your bindingsource to an ObjectDataSource (not quite the same as the ASP.Net thing). In VS IDE, open the Data Sources tab and click "Add New Data Source", choose object and select the Data Access layer component you wish to use. Drag the newly added component from the Data S ...Show All

• Visual C++ use templated base class declared in 1 C++/CLI assembly in another C++/CLI assembly?

  Hi, In C++/CLI, is it possible to take a template base class declared and defined in one assembly and use it as a base class in another assembly If so, how IOW: assemblyA: template < typename T > public ref class Wrapper : PtrWrapper< T > { protected: Wrapper( T* pObj ) : PtrWrapper<T>( pObj ) { // do something } ~Wrapper( void ) {} }; assemblyB: public ref class Batch : public CoreAPI::Wrapper< cBatch > { }; where T is an UNmanaged type (and cBatch is also). Both assemblies are DLLs, and both are CPP/CLI, if that matters. Wrapper is being successfully used as a base for many classes in AssemblyA. I can't get this to work. If I just have a reference in B to A, ...Show All
