• .NET Development Reading any file format with FileStream

  I want to be able to send ANY type of file (Text, .Doc, .Zip,. Etc.) with sockets. Everything seems to be going as planned, except when I read the file, the bytes are little bit different. How can I correctly read (ANY) file, for transferring over sockets Real Line 1 of File: +o[C€‥46( § cgZ C)E xn[y"QO Cp After reading with code below: +o[C (46( ,' cgZ6C)K xn["QS Cp It seems I am reading the file wrong. Only a few characters are not being read correctly. Here is the basic code for reading the file: fs = File.OpenRead(@"c:\mailroot\MENU.pdf"); br = new BinaryReader(fs); byte [] currentBuffer = new byte [1019]; currentBuffer = br.ReadBytes(currentBuffer.Length-5); Logger.Log(Encoding.ASCII.GetS ...Show All

• Windows Search Technologies Vista 64 and Searching

  It appears that the 64bit version of Vista 64 build 5472 has limited searching facilities. OneNote 2007 for example appears not be be indexed at all even in the application. Searching is important to me so I want to get a bit of a feeling whether I should drop down to 32 bit version Is 64 Bit Vista development going to behind the 32 bit version in areas for some time Agent86oz, Let me check with the OneNote team and see if I can get more information. I know that OneNote developed a specific IFilter to work with the search features in Vista and I'll have to see if development on that IFilter differs between 32 and 64 bit.

• Visual C# Variant in C# ?

  I’m coding in C# and I am working with a COM object that I earlier in C++ made this call: COleVariant varBeforeEnd(DISP_E_MEMBERNOTFOUND, VT_ERROR); hresult = pTemp->Add(knownObject, &varBeforeEnd ); How do I make the call in C# The IDE in VisualStudio say that the Add(…) function should have parameters like this: Add(KownObject, ref object); Any tip what to do with the second parameter I’ve tried to block some primitive types like int and bool to an object, but I only get exceptions… All tips are welcomed! Have you tried the IntPtr type it has been designed specifically for interop. ...Show All

• SQL Server convert word doc to pdf

  I have to convert word doc to pdf file use asp net. I think maybe it possible make report in the report services, and then save them in pdf format. but I dont know if I can make report from doc file. and also if I can get the url of the file by query string. Is it possible thanks! Do you have static Word documents that need 1-time conversion, or do you have Word documents that represent report styles or definitions that you want to export to PDF regularly with different data In the first case, I'd say RS is not the right tool. In the second case, I think you'll get good results by designing the report definition from scratch using Report Designer, using the Word documents as prototypes. ...Show All

• SQL Server Cannot open user default database. Login failed.

  Hi I am developing an asp.net application in Visual Studio 2005. The application was displaying in the web browser as expected but now i get the following error appear. Server Error in '/EMPRINT_STREETSIGNS1' Application. The server stores the information of your database. The server is defined (as of definition in SQL Server) as a SQL Server instance. if you have problems connecting to one server (instance), because either the database does not exists (or you have no permissions with the user to access it) and you change the server (instance) name to another server (instance) you probably have the database installed on the latter one. So if you want to use the first instance you will also have to install the database on this machine and ...Show All

• Software Development for Windows Vista Video with SideShow

  Is it possible (or realistic) to run full speed streaming video of any kind with a sideshow gadget on an aux display What you are describing is possible, but there are a few considerations to take into account: The most taxing gadget that has been released to date is the Windows Media Player gadget. The now playing page in the WMP gadget is updated once a second to reflect the current track progress of the currently playing track. We have found that all of the Windows SideShow devices we have now can handle this scenario. With that being said, the way you would write a gadget to do what you describe would be by sending all of the images of the tachometer to the device (say 10 or so images), each wit ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All
