Declared Variables With SQL Statement?
Aug 20, 2010I have a simple table in an access database that I'm using in a VS2010 project. I have a combobox control that a user can select the horse power of a motor. I then take that selected value from the control and copy it to a string variable called gstrSelectedHP. All I want to do is run a query that will pull up the full load amps of that horse power motor from the table. I have the query already, but I need to somehow put the gstrSelectedHP in the WHERE part of the query so that it only returns that value.

.net - Override Variables Declared In A Class?
Dec 16, 2010I'm trying to create a generic Controller Class for generic events. But these these events still need to access their class variable. So my idea is to create the Base Controller Class with a ModelBaseclass variable as _ClassVar, which is inherited by all of the other class Controller classes will derive from. But I want the derived controller classes to override the _ClassVar with whichever one they need.
I want to do this, so the ControllerBaseClass can have all the generic functions that all the Derived Classes would use.
Model :
Public Class ModelBaseClass
Public Overridable Function Foo() As String
Return "Name"

View 1 RepliesVS2008/VB: Moving Subclass VB Code To Inherited Base Class - Where Should Variables/objects Be Declared
Jun 3, 2009In re-engineering a windows forms application, I find that a lot of code-behind in the various form classes is duplicative and I'm trying to centralize as many procedures as possible into a base class which can be inherited and used by the subclassed forms.
This process seems to be going well and is making the code in my subclasses much simpler and hopefully easier to maintain, but I'm not sure where to draw the line between leaving code in the subclasses and engineering for generic resusability and moving it to the base class.
Specifically, in some subclasses I have code which manipulates variables and objects specific to the subclass, and although I could move the code-behind into the base class, the base class code references specific objects which are needed to compile. For example, each subclass manipulates a databound datagridview and form detail controls which allows the user to select between multi-record and detailed single-record views of a datatable.
In Visual Basic 2008 do I need to declare dummy data objects in the base class so that the base class will compile? Or is there a way to indicate that the data objects will be provided by the subclass?
Public Variables In Module "not Declared" Windows 7 64bit?
Nov 4, 2010I have a VB .net application which works fine on a 32 bit systems. We tried using it on a 64bit Windows 7 system but it failed. So I set up an environment in a VM (windows 7 64bit VS 2005 SP1 all updated) and started debugging there. The problem I come across is, I have a module (Public variables and function declarations from a driver provider FTDI). When a function from module is called the result is saved in a variable also from module. But the problem is the variable is not declared.
View 1 RepliesVariable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared
Aug 24, 2009I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

View 1 RepliesUse A Variable That Has Been Declared In Program In Xslt?
Oct 13, 2011In my xslt file I want to apply templates to the xml but only if an id of that piece of content within the xml matches an id calculated in vb.[code]...
ContentparId is the attribute parId of Content in the xml. I want to compare this with mnPageId which is defined in vb (a foreign reference is passed through and the pageId that matches that foreign reference is returned)
I know the rest of the code does what I want it to do because if I manually change mnPageId for a correct pageId then I get the xml that I want back.
So, is it possible to use a variable that has been declared in vb in xslt?

Set Variables To Nothing At End Of Program?
Dec 5, 2011I had to write a program for my class today(I don't like VB.NET, I like Java though) that created an Exception. Is it good practice to set variables to Nothing at the end of the program? In Java, there is the garbage collector so it will automatically delete variables if they are not used again. I don't know if VB.NET has this so should I keep what I have at the end of my code?

View 1 RepliesArray Of Variables - Put Together A Quick Program For Database
Nov 17, 2009I'm trying to put together a quick program for our database, I haven't touched VB since vb6, and we have 2008 .NET now. my question.
Ideally I'd like to make an array which can hold multiple values...such as

Job[job#].jobsupervisor
So there would be a Job array, and then different values contained within that. I can't seem to make an object or whatever which allows me to hold different variables inside it.
Pass Variables From Php Script To Program Application?
Mar 14, 2012I am developing an VB.NET application that reads data from the serial port and tcp socket, then I'm processing this data and store it in Database server. This application will be started all the time as long as the computer is started. On the server there is installed an apache server with some php scripts representing the "visual interface". From there the users can see the readed data from the VB app. The need is when an event appear in the apache server (such as button pressed), some data to be passed to the running VB app, and eventually trigger an event on it. I've considered some variants like start an timer that reads continuously some tables from the database that the php script writes onto, or read an xml ot text file, but I think that this may slower the communication and it is a source of exceptions or errors.
For example: An user opens a webpage, just to say test.php. On the page there is a button. The user pushes the button. The result of pushing the button has to trigger an event on the VB app and cause sending data trough the serial port or tcp socket. OR - The VB app has a timer that scans for pressing the button on the test.php.

Save Variables To Be Recalled Next Time The Program Runs?
Nov 9, 2009I am creating a very simple game for a project. There is opportunity for bonus marks, and one thing I would like to do is be able to "save" the game. The only thing I need to do is save about 4 variables to be recalled the next time the program runs.
What is the best way to do this?
I have searched Google, and there are ways to link the program to an Access database, but that seams a little extreme. I tried seeing if you can make an XML file to hold them, but I can't really find any good information.
