• Visual Studio Express Editions Databases (lots of 'em!)

  Hi there, I am new at Visual Basic Express, and am in the process of planning a Visual Basic Application. The project will rely on a a database - I am uncertain on a number of things. The data will need to be accessible in the office of the company - I was thinking of either on their NAS, or hosted on the Web. a) Which is better -Microsoft SQL Server or Microsoft Access I know that if I pick Microsoft Access, I can upload it onto a host no problem, and also put it on the NAS. If I was to use SQL server, would I only have to place the mdf file on the NAS b) Is it possible ...Show All

• Visual Basic About foreign characters

  I am reading characters from a file (file paths) into my visual basic program. My system (XP) understands the characters but when brought into .net, they are ignored and i get the following message "could not find a part of the path." These characters are Swedish. Is there anyway read these characters. The problem is the encoding I'm not sure how your reading the text from the file. If your reading the text in VB 2005 then something like Dim s as string = My.Computer.FileSystem.ReadAllText("c:\foo.txt", System.Text.Encoding.Unicode) otherwise Dim s As String = System.IO.File.R ...Show All

• Visual C++ Visual C++ compiles much slower on dual core processor

  The Background:  I recently upgraded from a 2GHz AMD Athlon machine to a 3.2GHz Pentium D dual core processor, thinking that my Visual C++ (.NET 2003) compile times would decrease significantly.  In fact, it went the other way round.  One of my library projects requires 11 minutes to compile on the AMD machine, but takes 25 minutes on the dual core machine.  My entire set of projects compiles in about 4 hours on the AMD machine, but in 8.5 hours on the dual core.  The same slowdown occurs with the .NET 2002 version and VC6.  I am awaiting delivery of Visual Studio .NET 2005 (apparently Progra ...Show All

• Visual C++ array of class objects

  Hello all. I am new to C++ and I just have a couple questions. Im working on a version of the game of life which can be found here ... First off, I am reading a file which contains 1's and 0's, creating an object for each 1 or 0, and then putting all of the objects into an array. I think I have that working but this is where I am getting lost.. I already have a method from when I did this same project but didnt use objects (just the integers). I have a method called 'play' which has two parameters: the array and the size of the array. I cannot figure out how to pass the array of objects into the method. Someone told me what the method header ...Show All

• Visual Studio Team System Schema-independent repository backup

  Some source control products support schema-independent transparent dumps of all revisions in the database, opening up the possibility of salvaging critical data in the event of unrecoverable database corruption.  Furthermore, if incremental dumps are supported (i.e. all revisions that were checked in since the last backed-up revision), and if dump files can be replayed into an empty repository to restore a working database, a very powerful recovery mechanism results. Are there plans to provide similar functionality for Team Foundation Server   If not, what are the existing plans fo ...Show All

• Visual C# Unable to load class library

  I wrote a managed wrapper in C++/CLI and compiled it under AMD64. Now I wrote a client in C++/CLI too and this works well. Trying to do the same in C# I got everything to compile but when I run it it says: Unhandled Exception: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E) at MyClass.Main() This is weird though. I compiled the C# file for 'anycpu' but trying to set the platform to x64 did not do any difference. The class library is even located in the same directory.  It was compiled using the RC:         csc /out:test_cs.exe tes ...Show All

  Hi, I am very new to SSRS and wanna know some very important things to begin reporting in it. I am developing an ASP.NET application where we report using datagrids. i now want to convert those reports to SSRS Reporting. but the problem is that all the queries of those reports are dynamically formed based on the querystring parametrs that the ASPX page recieves.It is something of this sort.... stringbuilder.append("Select ..... from ......"); stringbuilder.append("where ...."); if (request.querystring["id"]==1) { stringbuilder.append("and id = ... and name =...."); } stringbuilder.append(" and lastname like '%d'"); It is of this sort. so y ...Show All

  I'd like to obtain the local machine's serial number using .NET 2.0.  Does anyone have any sample code I've used WMI a little in VBScript over the years but each time I have to refer back to a sample to remember all the little tricks to getting it to work.  Whenever I need a script however I turn to TechNet's Script Center.  This site already has a bunch of scripts, a script writing tool and great support for using WMI and scripting in general.  The following section of the site provides information and example scripts on how to obtain hardware information such as processor and BIOS info ...Show All

• Visual C# Attribute refuses cast

  Hi! Edited to rephrase question: The following code is driving me nuts! I am trying to read the IDEiconAttribute   from each class (e.g. ConsoleInput ) in a library. But, I cannot access the attribute (object) I retrieve as my IDEiconAttribute  , so I can't call the IDEiconAttribute. Icon property. It refuses to be cast to IDEiconAttribute , even though when I print out the type, the type is IDEClassLibraryNS. IDEiconAttribute. In fact, I get the bizzare message "cannot cast IDEClassLibraryNS. IDEiconAttribute to IDEClassLibraryNS. IDEiconAttribute". Why does this work (in my case)     obj ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. HLSL shader: texture lookup with "indirect addressing"

  Hi all, I wrote an HLSL shader which reads one texture and uses the result as the texture coordinates of a second texture lookup (some sort of "indirect addressing"). However, the second texture lookup always returns 0; when I use constant values everything works fine. Can anyone explain this behavior I tested everything else, the problem must be due to the shader itself. I can reproduce the problem with any shader version from ps_2_0 to ps_3_0.. Thanks for your help! void F_indirect( in float4 wpos : POSITION, in float2 inCoord : TEXCOORD0, out float4 color0 : COLOR0, uniform sampler2D FPE0, uniform ...Show All
