• .NET Development .Net 2.0 InvalidCastException when passing COM invisible object in COM event

  Hi, In .Net 2.0 I'm getting InvalidCastException "Specified cast is not valid" when I'm passing ComUnvisible object to event as parameter of type Interface. The case is: I have a .Net class as COM object that is consumed by unmanaged client.

• Visual C++ Overriding OnFileSave()

  Hi, I am trying to override CDocument::OnFileSave() in my application. This is what happens when the save button is clicked: - Control goes to CDocument::OnFileSave in doccore.cpp - From there it goes to DoFileSave() - From there it goes to DoSave(NULL) I would want the Savedialog to be displayed in my application and let the user choose where to save and the name to save. I have this class CHDUDoc.cpp and I have this method which tries to override OnFileSave(). I just have these lines of code in my method, BOOL CHDUDoc::OnFileSave() { AfxMessageBox(_T("Right here")); //OnSaveDocument(lpszPathName); return TRUE; } But this method never gets triggered, instead it always goes to the doccore.cpp file. Thanks for your time!! ...Show All

• SQL Server Change the date format of a smalldatetime column.

  Hello people. Please, is there any way to change the date format of a smalldatetime column of a table in SQL Server Express What I mean is that the default date format for a column which type is smalldatetime is "MM/dd/yyyy" but I'm developing a localized application and the date format that I would like to use is "dd/MM/yyyy", so I would like to know is if there any way to change this. I know that I could write some code in my application in order to do the conversion, but I would like to avoid this because I'm using the databinding property of the control and if I have to write a piece of code in order to do the conversion, I will loose this functionality. I'm currently using WindowsXP SP2, SQL Server Expr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed vs Unmanaged, Primitive design and .NET

  I actually have three separate questions here. Please bear with me. Managed vs Unmanaged I searched several post and didn't find the answer I was looking for. Simply put, if you are designing a 3D game engine that needs to push 30+ frames a second, would you even consider using a managed language It seems to me that when the garbage collector kicks in your frame rate will/may plummet. What is the concensus on using managed vs unmanaged code in a game engine Primitive Design I have built a rudimentary 3D engine using good OOD where the primitives (points, polygons, lines, etc.) provide methods for their management and transformations. If I have a model with 100,000 points, each point carries the overhead of the virtual function table and ...Show All

• Visual C++ How do you create a pointer to class funcitons (not members)?

  Hey, I was jsut wondering, how do you create a pointer to a function that is a member of a class Note that I don't want to make a pointer to member, I just want to be able to do something like this: class ClassA { public: void SayHello() { MessageBox(0, "Hello", "", 0); } }; int main() { ClassA a; void (*ptr)() = a.SayHello; // this would be how i would suspect it to be done ptr(); } How do I acomplish this This would work if the class function is static. The problem is that your pointer knows naothing about the object you want to use. Hopefuly I didn't made a syntax error... (the syntax is horrible) class ClassA { public: void SayHello() { MessageBox(0, "Hello", "", 0); } ...Show All
