I decided to try the Code Analysis tool that came with VB2010 (at some levels). It produced LOTS of fascinating comments. Many of the comments make no sense, such as one about not disposing of a type on all paths when there is only one path that ends with an explicit call to object.Dispose. I think the analysis engine is looking at some of the calls, but they all return to the caller properly.
When running code analysis on my project, I receive the following message:
CA1051 : Microsoft.Design : Because field 'ClassName.VarName' is visible outside of its declaring type, change its accessibility to private and add a property, with the same accessibility as the field has currently, to provide access to it.
Public VarName As String to this:Public Property VarName As String
I don't understand why the Property keyword is so important in this particular case. Can anyone provide an explanation as to why changing this member to a Property makes a significant difference to code analysis?
Does anyone found good working QR Code library over the net? I already downloaded couple but both of them had errors once VS2010 tried to upgrade the version from .NET 2 to 4.

If you want to create a commercial application and sell it, what is the correct way to obtain a copyright or trademark to the program and its functionality (if you can even do that) If I wanted to give to a potential client to demo, I want to cover myself in case it gets in the wrong hands (read "another developer") Is it as simple as saying "Copyright so and so" in the App Settings?
Is it possible to set a form Topmost setting only for one commercial program?Say my program is A and commercial program is B... I want Topmost setting for program A will only work when I working on program B, and when I switch to other program than program B the Topmost setting for program A back to false.
I'm writing a VB.NET app that will control a commercial backup product. One of the things I need to do is loop through all existing jobs and look at the source drive. I am able to do this in VBScript very simply like this:
[Code]...
However nothing I try in VB.NET works. I'm pretty sure it has to do with the fact that the com functions are returning variant data types and arrays (specifically GetVolumes). I have tried using string arrays, object arrays, and even wrapping the return value in a VariantWrapper and I always get errors such as "not implemented" or "the parameter is incorrect." If anyone is bored and wants to write some code I'll gladly give it a shot and report back.

I am currently writing a program in Visual Basic 2008 express edition to read and write to tags on an Omron PLC. I am using the DeviceXPlorer OPC Server V4.1.1.1 program to connect to the Omron PLC. I have made two programs, one is a form program which works fine, two is a windows service program where it does not let me connect to the OPC Server. The connection code is identical, the only difference is the windows service code is called by a timer. The timer works fines and jumps into the connection code, but stops at the line
Where can I get a free code signing certificate for signing my applications? Ascertia used to give them out for free but apparently they don't anymore.
I'm a rookie in Visual Basics 2008 and i am trying to make a program to communicate and read tags from an Omron PLC. I am trying to connect to the PLC via devicexplorer opc server, because it can let me read DInts and Reals from the PLC tags. I have referenced Microsoft ActiveX Datas Objects 2.5 Library and OPC DA Automation Wrapper 2.02. I have made some code which connects to the PLC "in a form", but I cannot use the same code and connect through as a Windows Service program.Here is my code,
Public Sub OpcConnect(ByRef Items() As String, ByVal PLCType As Integer) Dim j As Integer Dim TempSvrHandles As Array[code].....
Note: this code is run in a timer on the windows service, it connects properly to the "RSLinx OPC Server", but "Takebishi. Dxp.1" (devicexplorer shortcut) exits the sub routine at MyServer.Connect(PLCServer) ' connect to the opc server.
I'm reading data from the microphone and want to perform some analysis on it. I'm attempting to generate a spectrum analyser something like this:
What I have at the moment is this:My understanding is that I need to perform a Fourier analysis - a Fast Fourier Transform ? - to extract the component frequencies and their amplitudes.
Can someone confirm my understanding is correct and exactly what type of Fourier transform I need to apply?
At the moment, I'm getting frames containing 4k samples from the mic (using NAudio). The buffer I've got is 16bits/sample (Signed Short). For reference, the above plot shows approx half a frame I'm coding in VB so any .Net libraries/examples (preferably on NuGet) would be of most use. I believe implementations vary considerably so the less I have to massage my data, the better.
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
I'm using VB 2005, and am hoping to have streaming video to my application with some sort of video analysis. Right now as a test, I have an axWindowsMediaPlayer control playing a video from a URL. I'm figuring I need to be able to detect the colors of the pixels in the video for simple analysis, but I haven't been able to do this yet. I've been able to view the pixel colors in every area of the screen except for the media player window (just shows up black, as if you were to make a screenshot of the media player video). Is this at all possible to do?
Is it possible to consume a web service via code and not the normal way? Reason I ask is my app makes a decision on which of two web services it needs to connect to at run time, and I need to be able to do this with changing it at design time.
I want to make a program that will ask the user to enter the service reference URL in the text box then click a button to add the service reference. how to add and remove a service reference?
I intend to choose developing a Web Content Management System using asp.net with VB.net 2008 but I'm not sure about how long it takes to program such system. Is 4 months enough for developing such system? This 4 months is the duration of this semester and Includes about two months for analysis and design and the rest is left for implementation.
I have been tasked with getting a asp.net (vb.net) talking to an analysis services engine on our production servers. The web server is a separate machine from the web server.The web server runs as the IUSR_ user.The application (of course) works on the development machine which has both IIS and Analysis services on it.The problem I see appears to be a permissions error (returned in the browser by the asp.net app):An existing connection was forcibly closed by the remote host ....
it is described in a similar post here: http:[url]......I am not a system admin, nor am I an expert in analysis services (why have I been tasked with this you ask? because other people haven't been able to get it working and it has fallen on me). I have tried creating and adding the user (IUSR_) to the sql server and added that user to the role. While that worked on my local machine, it did not work in our production environment where the sql and web servers are separate.
With this assignment, you are provided with an incomplete object-oriented implementation of the GAME MANIA software system based on Visual Basic 2008. The specification and the subsequent modelling are explained in a case study titled Game Mania: GAME AND GAME CONSOLE RENTAL STORE.
An implementation of the following classes are made available as the basis of your development work:
Note that the user interface provided is very basic. You need to change it, as you feel appropriate so that it will reflect the required functionality. For example, in the present implementation version, no provisions were made in the user interface for querying and handling fines associated with late returns.Providing this aspect in the user interface might be necessary as part of handling renting of games and game consoles.
I have a website where people do the data entry. I have data stored in SQL server.Now I need to push the data to 3rd party to do some analysis work.What are my options to do this kind of job?
I'm working in VB.Net and I'm trying to make a piece of code more generic.In fact, there's a big Select Case statement that build a ProxyServer based on a value passed in parameter (a string).
Select Case _strNteraHL7 Case Constantes.NomPRPMIN306010 strUrl = ObtenirUrl("ProviderDetailsQuery", _strVersion, _strEnvir, True, _blnSimulCAIS, _blnSimulPDS, _blnSimulPDSSIIR, _blnSimulPDSInteg)
[code]....
or something similar, so I can remove all those big switch cases, that repeat the same thing 30 times.objWsHL7 being an object or type "object" at compiling.Again, in another switch case statement,
objMsgHL7Out = _objWsHL7.ProviderDetailsQuery(_objMsgIn) objMsgHL7Out is a System.ServiceModel.Channels.Message _objMsgIn is a System.ServiceModel.Channels.Message _objWsHL7 is an Object
Need to use the create method of the AX 2009 ReturnOrderInService web service in a vb.NET aspx page to create an RMA in AX.The code I've written below creates the RMA in AX, but doesn't show the line details in the AX RMA form, even though the records are in SalesTable and SalesLine.Is a record needed in InventTrans or is there a missing InventRefId value somewhere?[code]
What I'm trying to do is monitor a file and if it exists then then copy it's contents to a database, then delete the file. Currently it only adds the data one time and does not delete the file.why it will not keep adding the data or deleting the file?
I did a search on the internet but came up with very limited results. I'm using asp/vb and need to create a n application that does the following steps:
1. User defines web service URLs to WSDL pages .. populated in combo drop down (already coded) 2. User selects web service - Clicks Connect 3. User is prompted for any input fields the web service requests. 4. Output (in XML) is displayed after input fields are populated.
I know how to reference web services in the development environment, and use them... but have no idea how to dynamically create them and show the input fields requested.
