I am using vb2010 and the like @lastname +'%' to try and create a search query. It seems to work until I try the test query which brings up nothing within the test query window. Sometimes it even seems to wipe out the data I have put in for testing. I did get it to work once in one project.

View 13 RepliesI'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?
View 4 RepliesI've got the hang of using dates now, but I haven't learned how to test multiple results of a query. I can return a value from a query, but I'm unsure how to return many without putting them into a data grid view or an object on the form. (In Visual Basic)I have to check when a particular investment needs to be bought or sold, there will be more than one in almost every case. I've got the function to find out the interval between the months, checking if the asset is bought or sold in month x, but I'm unsure how to test it against multiple assets at once - nor do I know the best way to do so.

View 1 RepliesI'm trying to draw some text using GDI (i.e. using a graphics object). It is done using the basic method of creating a path, adding a string to it and using a brush to fill it.
The only tricky part is that I need to apply a soft edge wipe to it. To describe what I'm trying to do better, I've uploaded an example done in photoshop: [URL]
What is the best way of achieving this? I need to be able to control the mask that is creating the soft edge - i.e. the position of the gradient, the width of the gradient etc.
Ideally I'd like to do it using the graphics object and not dipping into .dlls - but at the end of the day I'll do whatever it takes!!
I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following:
IUtilisateur
IGroupe
IUniteOrganisation
These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc.Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more.

I have used a data repeater and linked it with the data source. The program lists all the names of clients from the database with an ID number and also a URL.My first question is how can i make the url that is displayed as a link label, link to the default browser when clicked. I normally use the Shell("c:/program files/internet explorer/iexplore.exe "URL HERE") command but i'm not sure how to make this work with the data repeater?
My second question is to do with starting services, i need to take the ID number from the current data repeater record and then place it within a service name, for example if the service was callled Client_** the two ** represent the client ID. This then needs to start the service when button is clicked on the current record on the data repeater.
My third and final question is how to query a field in a current record of a data repeater, for example if i wanted to query a field called ID for that current record shown, is there a function i need to use to call the information?
I have a combobox that I am populating with the contents of a dataset (from an access database). The field that it is showing has lots of values that repeat. I want to remove the repeats of the data so that only unique records are shown in the combo box. I imagine this can be done with the SQL for the data adaptor? I tried: "SELECT type FROM products GROUP BY type" and "SELECT DISTINCT type FROM products" but both still showed the repeating records.

View 1 RepliesLet me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.

I have the following code that needs to connect to my four spreadsheets for FileName(). I havent built the loop yet for the other three, but I am so used to working with a variable. Is this the best way (datatable) to get a single cell from a spreadsheet and if so how do I view the data once it is in the datatable? Ideally I would like myDataArray(3) to hold the 4 cell values. Please help. I am stuck. I want to be able to get the cell value $K2 form each sheet without invoking Excel. I think I am close, but dont know how to get the data from the table. These four cell values will be displayed and then emailed to our Country Director.

View 5 RepliesI have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
Here is the code:
Function getData(ByVal id As String)

What i want to do is use specific rows from a table in a database and input the individual rows each in its own textbox.
