Application Which Communicate With One Data Logger Unit (temperature Monitoring Unit)
Jul 21, 2010
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 will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.

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.

I have a project to do in Visual Basic.My problem is that the outcome is always wrong (ex. instead of 2011 it gives 2000). And i cannot set as Desired unit the Inch(1) or feet(3), it gives the Infinity error. And if i put as Original and Desired unit the inch(1), the outcome is "Not a Number".[code]

I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?

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.

Public Sub CheckOutputFileInfo()
ReportPath = "D:temp est.txt"

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......

I 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 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.

I 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.

Private Sub txtbox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtbox1.enter

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.

Is 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.

I want to include an optional parameter in a function statement that is of the type Unit. For example:

Optional parameters require a default value, but I cannot figure out how to set a default value for a Unit type.

I 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.

I have a constructor that looks like this:
Public Sub New()
MyBase.New()
ws.Url = My.Settings.WebServiceURL
End Sub
(ws is private)
Is there any point in unit testing this?
The class did not previously have this constructor.

Usually when you add one (in Visual Basic), it pops up a message asking if you want to enable an option that lets the test access things like private methods etc.
However, I am editing a solution that does not have this enabled. I'd like to enable it so my unit tests will work, but I can't find the setting.
Can anyone tell me how to enable it after the project has been created?
