• Windows Search Technologies Writing Isearch Protocol and IURL Accessor

  Hello, I'm a Software Developer (Trainee). I'm entrusted for "Incorporating Windows Desktop Search with the facility to index and crawl URLs". I found it really difficult, since am a fresher. I don't have much knowledge of these. Anyhow, I found stuffs like Isearch Protocol, IURLAccessor, IFilter, etc that'll fulfill my requirements. But, still I don't have idea, how to use these stuffs. Can anyone help me out. It's urgent... Regards, Vikas Kumar Hello Vikas, You can crawl the intranet using existing options in WDS. You'll have to right click on the spyglass in the system tray and then select options. Once there, click on the indexing section in the left navigation pane. From there, select Custom, click ...Show All

• .NET Development Asking too much of Visual Basic Or The .Net environment??

  We have been putting together a SMTP Filter in .net (using vb) which seems to be out of the scope of what the .net framework can support in terms of performance. The application its self is very basic really, all it does is listen on port 25 for new connections, for every new connection it receives it makes a second connection to our Exchange server. It then passes the messages it receives from the client to exchange and anything from exchange back to the client. which works perfectly. What it also does is save the contents of the E-Mail in to a string builder so we can rip it apart to scan/save the E-Mail into a database. This is where the problem lies. When we have detected the SMTP client it sending the body it will append t ...Show All

• SQL Server sql server 2005 - CTE vs Table variables

  Hi, What is the difference between CTE and table variables. I read that CTE is used so that the tables do not get persisted in the database. Do the table variables have the same efficiency i.e. not persisted in the database. Can you throw some light over here if you understand the two concepts clearly please Thanks Hi, A Common Table Expression (CTE) is a temporary, named result set. Once created, a CTE can then be used in subsequent statements in the same SQL batch. This provides two benefits. First, it allows queries to be written in a more clear and concise manner. Second, because CTEs can refer to themselves, they allow the creation of recursive queries. In previous versions of SQL Server, sto ...Show All

• Visual C++ Single vs Multiple dlls

  Hi, I am building an ATL COM DLL component. There are many functions to be exported (around 100). I want to ask about the performance gain/loss in case I build a single DLL exporting all functions or in other case build multiple dlls. Thanks & Regards, Omer Javed If all functions are used in the same client, it is better to keep them in one Dll. Loading one large library to memory is faster than loading number of small libraries. ...Show All

• SQL Server Setting Local Report Data Source

  I am a college professor and am updating my undergraduate database course to use Reporting Services as the reporting tool. The student labs cannot run IIS so I assume that using server-based reports is out and am looking at using local reports and the VB ReportViewer control. For several reasons (waaayyy too long to list here) I do not wish to use the drag-and-drop datasets that seem to be the core of the ADO.Net 2005 architecture. Instead I prefer to create connections, commands, and datasets in code and to set data binding and manage data updates in code. All command objects map to SQL Server stored procedures. I need to be able to do the same thing with reporting services local reports but have run into a brick wall in getting the ...Show All

• Smart Device Development Visual Studio 2005 and Mobile 5.0

  Hi there, i've installed "Windows Mobile 5.0 Pocket PC SDK.msi", and supposely it would include some sort of plugins for VS2005. However, in VS, on smart device's projects, i only have: - pocket pc 2003 - smartphone 2003 - windows CE 5.0 Also, on "Device Emulator Manager", i also only see these emulators... Do i need to install something else Tnks Nelson, should installation indeed run without problems we would not be having this little chat and you would be using templates and emulators just fine, right So obviously installation was not OK even though it did not hang. That’s because your anti-malware silently blocks the script instead of ...Show All

• Visual Studio Express Editions Runtime requirements for published application

  Hi! I am a newbie to VB.net and I am currently busy working on one of my first projects. As I am nearing the end, a few questions have dawned on me. One of them is what the requirements are when I want to distribute one of my applications. I have used a few .NET references in my application, therefore: is it neccessary for the user to install the complete .NET framework 2.0 for the application to work properly Is there perhaps a smaller, "run-time" package (or something like that), that I can include with my application Thanks Johannes j_o_h_a_n_n_e_s wrote: Is it legal to distribute the package with the software Yes, Completely legal ...hence the name "redistributable" ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render to texture and Volume Textures

  Hi, I would like to know whether Direct3D can perform render to texture to a "slice" of a volume texture. Its just like binding an slice of a 3DTexture to a frameBuffer Object in OpenGL. Is it possible Thank you. Yes. Are you actually sure you can bind a 3D texture as a valid target for a framebuffer object I know the extension states this but I was under the impression it was dropped. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problem with running XNA-Applications

  I have a problem. I can't start XNA-Applications on my second PC, although I had installed there the XNA Framework Redistributable and .Net 2.0. On my first computer (where I had installed the XNA GameStudio Express), all XNA-Applications run. (Boths PCs have the same DirectX-Version.) Perhaps I had forgotten something, but I don't know what. Thanks for any help (and sorry for my bad english). SteveKr Yes, I could do this. But each application (xna-apps from other peoples too) don't run. So I think, it's not a problem from my own games.
