Does anyone have a nice sample of a unit convertor handling multiple unit types that I can integrate in my application? I have found this one, but it is only handling one type of unit. For example I want to convert weight as well as volume from and to imperial units.
View 8 Repliesi am new to VB and am trying to make a metric to imoerial unit converter in VB 2008. I have created a form with 2 list box's with MM, CM, KM etc ....... and the other Inches Miles etc I have added 2lables with convert from and convert to and also 2 blank text box's the first one to choose the number i would like to convert and another to show the converted unit, I have also added a convert button.I am really struggling to find the correct code to make this work.
View 2 RepliesI'm a bit new to these forums but anyways let me get to the point. I'm trying to make a Unit Conversion Program on VB 08 and I am trying to make it so I don't use too many radio buttons, however I may use it if there is no other option. And I also have to make the program do it both ways
For Example I want to convert Fahrenheit to Celsius and Celsius to Fahrenheit in the same textbox or some sort of box.
I have written one application which communicate with one data logger unit (temperature monitoring unit) and download records after some interval. Unit continuously send current temperature which I have to show on screen and after each one hour I have to download log (all records saved inside unit at max 1024) from unit.
Now problem is after downloading log, application get hang or what we called working in background and resume after some time. If I pause debugger in visual studio 2008 it show control at application start (sub main) with message as "application will resume here after completing execution of current function". There is nothing in output window. So how can i trace is there any events got spool or what actually application doing in background.
I am attempting to make a unit converter that converts between km, m, cm, miles, yards, feet, and inches. I have a textbox that is used to input the value to convert followed by a space and the units (i.e., 56 km) and a second textbox where the user types what unit they want to convert to (i.e., cm). When converting, the output will be displayed in the second textbox. (I know this is complicated, but this is the way it is to be done). I am doing this using sub and function procedures and If blocks and Select Case blocks (i.e., keeping it as simple as possible).

I'm running some unit tests for a large VB.Net application I help maintain and am running into problems with tests timing out. The test run is set up so that there's no timeout limit on the overall test run, but a limit of 2 minutes per individual test. However, a couple of the tests take a lot longer than this to run, so we tried adding the timeout attribute to the test's declaration, i.e
<TestMethod(), Timeout(15 * 60 * 1000)> Public Sub DoSomething()
for a 15 minute timeout. However, the 2 minute timeout set in the test run properties seems to be taking precedence, even though it says that the timeout attribute should override it.
I am trying to create a unit test similar to how I would have done one in C# but am struggling with the lambdas in vb. Bascially I am trying to mock a class and then create a stub and return. In C# I would have done something like;
MockedPersonRepository
.Stub(x => x.Find(id))
.Return(person)

What code can you use to get the unit in a currency?
For example in 10,340.55 there is:
10 units for a thousand.
3 units for hundreds
4 units of tens.
1 fifty cent
1 five cent.
I tried to make an unit test for this method which is pretty simple only add an object into the data base and if it works well returns true

I have been assigned a task of exploring unit testing using tools available in the market.My question is how do i write an API that would help in writing unit test cases.Example i can use nunit to write something like this to check whether file exists in the given location.
<Test()> _
Public Sub CheckOutputFileInfo()
ReportPath = "D:temp est.txt"
[code].....
So when that code run the program don't switch.Say I want to
Open a file
Write something
Close a file
Way when I open a file, another thread want to open that same file. That means open a file get executed twice.
When i perform unit testing on routines, using the unit testing framwork provided by VSTS, i need to get a output of the unit test and result on to a document (documentation). how do i do i do this?

In the project that i;m currently working on i;m not allowed to touch GUI for anyreason that includes program testing. I'm in bit of s frustration becuase prior to this all must application were developed and tested using GUI. Typicvally it wold take a me a week to develop an app now it taking more than that. Especially the TDD with Unit testing. The documentation kills more time too......
View 4 RepliesI really like the moq mocking framework. I've used it on several projects. Unfortunately, one of my customers is demanding we use VB.Net. Not my preference, but hey, .Net is .Net, right?I've heard that moq has some trouble with VB. Is this true? Is so, what sorts of trouble? I would expect it to work fine given the language agnostic nature of .Net.
Should I look into using some other mocking framework for use with VB?
I have a unit test project and a project A that refers to the dll B. When make changes to the dll B and build my solution again I get an error meassage: could not load dll B or one of it's dependencies when i try to run the test project. The dll B does not exists in the references of the test project.
View 11 RepliesI want to know is their a way to display the imaginary unit i. For example when I calculate the square root of -25, I want the program to display the answer 5i instead of NaN (Not a Number). So is their a way to display imaginary numbers and even complex numbers in visual basic 2008.
View 8 RepliesI created some string resources in My.Resources. I want to use those resources in my unit tests.How do I expose these resources to my unit test project?I tried simply setting the Access Modifier to "Public" for the resources. This made it so that I can compile the code, but it is ignoring the culture setting.
Bo.My.Resources.Culture = New CultureInfo("en-GB", False)
LocaleTest(Bo.My.Resources.Yes, "Yea")
I am writing a test unit (in MSTest) that consumes an XML file located in the testing project. I have this (solution name is BusinessLogic, project name is BusinessLogicTest):
Public TestContext As TestContext
<TestMethod()>
<DeploymentItem("BusinessLogic.BusinessLogicTestTestData.xml")>
<DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML",
"|DataDirectory|TestData.xml", "Row", DataAccessMethod.Sequential)> _
Public Sub ConvertIntToRoman_DataDrivenTest
[Code] .....
However, when I run the test I get an error: The unit test adapter failed to connect to the data source or to read the data. I belive it's something to do with my DeploymentItem and/or DataSource, however, I cannot find an example (in VB) that works anywhere.
Doing some homework on unit testing and in all honestly i just don't get why i get this error.
i got a simple method that select all text when tab and testing if the actually textbox1 is selected. I just don't get why i'm getting a nullReferenceException at target.txtbox1_Enter(sender, e)
Private Sub txtbox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtbox1.enter
Dim txtBox As TextBox

I've read about creating factories, and unit testing driven development and how it actually saves you time during the debug phase of development. I'm using some libraries for an entity framework (Entity Spaces, since we are not on dot-net 4.0 yet)
Since getting started seems to be the hardest part for me to wrap my brain around, How would I create a factory for an object that is unit testable on a simple method like so?
[Code]...
However when I call video, its giving me "possible null reference exceptions" errors, and indeed its throwing a null reference. If my constructor is declared public and shared, and is creating a new object, then returning it, why is it giving me null exceptions?
I'm wanting to create a load of unit tests to make sure my stored procedures are working, but i'm failing (i'm new to tests in visual studio).Basically I want to do the following:
<testclass()>
Dim myglobalvariable as integer
<testmethod()>
[code]....
The problem is because the tests don't run sequentially, tests 2 and 3 fail because the global variable isn't set.
Can anyone point me towards a complete scenario using MSTest,vb.net, with or without mocks,MVP (supervising controller)

how to convert a metric unit to standard. I will be converting Feet/Inches to Meters/Centimeters and vise versa as well as pounds/ounces to kilograms/grams and vise versa. I can input the values into my Textbox to where it reads " x'y" ," however, when I go to code the Convert button (the same button has to be used for all conversions) how to separate out the text and then perform the conversion.
View 7 RepliesIs there currently any possible way to report progress of my unit test? I have a test that could take up to a hour, and I don't want to sit there not knowing what % it is done with. I have tried writing with debug.print and trace.writeline, neither of which seem to work.
View 1 RepliesI want to include an optional parameter in a function statement that is of the type Unit. For example:
Public Shared Function NewTable(Optional ByVal TableWidth As Unit) As Table
Optional parameters require a default value, but I cannot figure out how to set a default value for a Unit type.
I would like to prevent all subsequent unit tests from running when certain conditions are met in a unit test. Is this possible in Visual Studio 2005?
View 2 RepliesI am having a problem with a unit test I have created. First time doing this so I am not sure why I am getting this error [code]Test method ETDS_Unit_Tests.LoginTest.ValidateUserNameTest threw exception: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server).This is the same connection that my software is using, and the software runs fine, only the unit test is failing. What I am doing wrong? It Seems to fail one time for each datarow in the table.Also, I am using a Linq Query in the method that I being tested. I believe that this may be what is causing my error.
