• .NET Development Activator.CreateInstance to call COM ActiveX DLL Component

  Hi All, I am trying to call a Delphi COM DLL to create an object within C#, VS 2003. My problem is the following: 1. I am trying to call the DLL from ASP.NET. This dll connects to foxpro tables on a unc. I have implemented impersonation via LOGONUSER and can access the network path from within ASP.NET just fine. My initial prototype had a reference to the above DLL which I then created objects from in the format DLL.CLASS c =new DLL.CLASS(). I think that the DLL is not running under the WindowsIDentity of the user domainname\user so I think it is running out of process.. Is that correct So what I was trying was CoCreateInstance, but had no luck even getting it to work. I see that I can use the ACTIVATOR.CreateINstance and p ...Show All

• Visual FoxPro query and fecth in parallel

  I'm working with Visual FoxPro 6.0 trying to work on two statements in parallel. The connection string is : "DSN=Visual FoxPro DataBase; SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=Machine;Null=Yes; Deleted=Yes;" In the code below I'm processing one query, after it is done I'm opening a new Thread that process some other query on the same table, my problem is that despite the fact I'm working in two Threads it doesn’t work in parallel the function SQLFetch() ends only after the " SelectThread" if over. The output of this program is: [6556] Select Enter [6556] Select Leave [6556] SelectThread Enter [6556] Before SQLFetch [6556] SelectThread Leave [6556] After SQLFetch I'm want to fix this problem so that t ...Show All

• Visual C++ Multiple inheritance and function overloading

  class A { public : int f() { cout<<"A::f()"; } }; class B { public : int f(int i) { cout<<"B::f(int)"; } }; class C : public A, public B { public : int g() { f(); } }; Why does the above program give following error error C2385: ambiguous access of 'f' in 'C' error C3861: 'f': identifier not found, even with argument-dependent lookup Where is the concept of function overloading and method signature go PS: The above program code compiles if you give A::f() inside function g() First of all, you should consider having your base methods declared virtual, for the sake of polymorphism You should declare virtual only those functions that are/sho ...Show All

• Software Development for Windows Vista TextBox in Aero Glass Margin??

  Hello, i'd developed an application in Visual Basic .NET Express and there i have a code, which makes a big margin in aero glass ( DwmExtendFrameIntoClientArea), so... ... now if i have there an textbox or an label or anything that's forecolor or backcolor is black, i cannot see the text, because for this margin, windows means, that black is the full glass effect and white is white and so on... how can i solve this problem, how can i make an label or textbox where my text is really black. I got most of this from a site that I don't remember anymore. You will have to add in some code to alow form dragging.

• Visual Studio Questions about Sandcastle

  I have some questions and observations regarding the July CTP of Sandcastle when using it to generate documentation. The generated CHM file doesn't seem to have an index. There's no Index tab displayed in the viewer. The generated CHM file doesn't seem to have search capability. There's no Search tab displayed in the viewer. When the CHM file is double-clicked to open it for viewing, the right-hand pane of the viewer shows a mostly-blank page with a small warning icon in the upper left-hand corner. This mostly-blank page goes away when any of the entries in the table-of-contents in the left pane are clicked. In the CHM file, the documentation entries for class constructors always seem to have ".ctor" prepended to them. The table ...Show All

• Visual Studio Express Editions Windows Mobile 5

  Is it possible to code for Windows Mobile 5 with the Visual Basic Express edition, as I notice the SDK for WM5 does not mention express, and also there is no "Device" in the Tools>Options menu of Express If not, is there or will there be an Express version of some sort to code for WM5 MatthewGuy wrote: How would you be able to do it in notepad I used to code a lot in notepad before I could afford vb.net 2003 standard :> It was horrible! Basically you just create your classes etc. and throw them at vbc.exe (the visual basic.net compiler) which is shipped with the .NET SDK. I think this is the method that SharpDevelop uses, or maybe they wrote their own compile ...Show All

• SQL Server Basic SQL Execution Question

  I have a table that contains a history of record changes within another table.

• Game Technologies: DirectX, XNA, XACT, etc. What does creators club include right now?

  I'm a little puzzled about what the creators club actually includes, I've checked the FAQs and can't really find an answer. I have however managed to find the following: "The XNA Creators Club is available on Xbox LiveR Marketplace for $49 (U.S.) for a four-month subscription, or $99 (U.S.) for an annual subscription. Both subscriptions provide aspiring game developers with access to thousands of game assets from Microsoft and key partners such as Turbo Squid Inc., as well as white papers, specialized starter kits, samples and technical product support to help turn Your World, Your Game into a reality."

• Visual Studio Express Editions PS

  Maybe it's not C#, but whatever it is, it's not familiar to me. What I want to do is to type in something like "ostream" and have it take me to an appropriate page. I did manage to naviagate to the MSDN help system (although I've already forgotten how I did that). But it did not come up with a search box or a useful index. Things are organized by categories, like input and output. I really am impressed with C++ Express. And the price literally can't be beat. But I must say, for a decade, every time MS improves a product, the help system becomes more difficult to navigate. I certainly don't know of a way to merge the two sets of documentation. It would be nice if you could! There is the online version of the documenta ...Show All

• .NET Development UDP broadcasting from C# to C++

  Hi, I have the following doubts 1) In my project, I have to communicate with more than one hardware board. I need to use UDP broadcasting in C# to find out the IP address and MAC address of all the boards. How do I do it. 2) The board firmware is developed in C++ and the application we are using to broadcast is in C#. Will it affect in any way Thanks for your help If the hardware boards support SNMP (as most network cards and routers etc will) you can broadcast SNMP queries at them. There's an example of such a beast in "C# Network Programming" published by Sybex. I've come across code samples from that book on various Internet sites from time to time. Google C# SNMP ...Show All
