Testing For Month Equals Zero With The Values Returned By An SQL Query?
Aug 3, 2011
I'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.

I want to be able to see if the values a user inputs into 2 textboxs equals the values assigned to a picture. I put these values in the picture's name and tag. Also the picturebox is getting the image from a random function correlating to an imagelist. How would i go about thisI thought of maybe using a checkbox and coding
If picturebox1.image.tag = ("12") _
and textbox1.text = 1 _
and textbox2.text = 2 Then
checkbox1.checked = true
unfortunatly when i debug it says the picturebox1.image.tag = Nothing

I implemented a PagedModel class to wrap around IEnumerable to provide paging data for grids in my MVC app.I used Resharper's auto-generated Equality code telling it to check the data, total rows, page number, and page size fields.[code]I found the call to Equals(other._ModelData, _ModelData) peculiar, as AFAIK, this checks that it is the same object rather than that the contained items are the same. Because my tests were failing anyways, I went ahead and changed it to other._ModelData.Equals(_ModelData) with no success. Then I reflected into it at debug time and found that other._ ModelData.GetType().GetMethod("Equals",{GetType(Object)}).DeclaringType was Object! Obviously, that would result in the failed comparison.I came up with a solution to create a EnumerableEquals method which compares every item in the two enumerables to confirm the are the same, but it seems sloppy. Is there anything I can do to use the normal .Equals method? [code]

I am creating an xml file with LINQ as follows...
Public Sub CreateXml()
Dim db As New MDataContext
Dim Customers = <gallery columns="3" rows="3">

Could i mix local values with the ones returned from the LINQ query...Something like the following?
Public Sub CreateXml(ByVal **Col** As String, ByVal **Row** As String)
Dim db As New MDataContext
Dim Customers = <gallery columns="& **Col** &" rows="& **Row** &">

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.

When Creating a query using the sear Criteria Builder. I keep getting the error:
"The schema returned by the new query differs from the base query".
I know this means that the error is due to the query attempting to return too little columns. I have 3 rows in a table but I want to display one. I am currently using a list box what alternative is there.

When i parse some html and get the fields i need using regex, the first 4 fields returned are fields i don't need, so essentially i need all fields returned after the 4th one.
vb.net '// First piece of data we want...
Dim stringID As New Regex("(?<=><optionvalue="").*?(?="">)", _
RegexOptions.IgnoreCase Or RegexOptions.Singleline)
Dim stringsMatched As MatchCollection = stringID.Matches(stringClean)
[CODE]...
Is there a way i can blank out the first 4 fields returned?

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?

I have a List<Object> where Object contains Name, Month, Type, Value.
is it possible to sum all the Value based on type, and then based on month?
I am using .NET 3.0 in VB.NET I was doing withe like 4 For loops, but its taking a while to run.
For clarification, I have something like this:
Name | Month | Type | Value
-----------------------------
hello | Jan | A | 1
hello | Jan | A | 2
hello | Jan | B | 2

I am trying to find a way to use a month calendar control as an object data source, such that when end user selects a given date, or a date range (1 week max), it will supply the date range criteria for an access query, and the results will wind up displaying in a data grid view below the month calendar. I am having a really hard time..
how to write the date criteria into the access query for something like this

The exception message I am receiving is this... "Year, Month, and Day parameters describe an un-representable DateTime."
Now I've traced my values being passed and everything is correct. Values loops through 1 to 12 but still I continue to receive an exception. Only way I can avoid this is by throwing a Try, Catch statement around where I'm passing over the value.
Here's my code..
001 Dim Calendar(11) As AppointmentBookControl.AppointmentBookControlMonthlyOverviewCalendarControl
002
[Code]....
Line '011 .Month = i+1' is where the problem is located. The values for (i+1) maintain within the bounds of 1 through 12..

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 want my game to tick over month by month at a set interval. I would use the timer control to get the interval. But how can I pause it? Say if one "month" is 5 minutes in my game and user hits pause. I would disable the timer but then when they unpause the game the timer would start from 0 again. This would make a "month" 9 minutes if a user paused the game in the 4th minute.

Right now I have an array that is unparsed. One of its elements goes something like this:
"Blah, 555-5555"
So it's a name and a telephone number separated by a comma. The instructions I have tell me to use a query to put the information in the array into a data grid view in two columns, one for the name and one for the telephone number. I don't know how to isolate each inside a query.

I am trying to use Linq to Xml to query attribute values that will be used to populate a combo box. My xml looks like this:
<Records>
<Record id="1">
<LogoPositioning>
<Brand id="26">
<Xpos>100</Xpos>
<Ypos>200</Ypos>
[Code] .....
My issue is with getting the attribute values. I tried this:
For
Each xattr
As
XAttribute
In
attr
cboBrandChoice.Items.Add(test.Value)
Next
However, I keep getting the following error:
{"Unable to cast object of type '<GetAttributes>d__8' to type 'System.Xml.Linq.XAttribute'."}
I'm new to using Linq so this error isn't making a whole lot of sense to me.

I want to check some values in a sql db without populating controls. I can select the row i want, but for some reason my mind then hits a blank, maybe its because its monday.I want to check a few bit fields in the row and if 1 - do something, if 0 do something else. In this case depending on which bit fields are set to what, id like to enable/disable various controls on my form.
Heres the code i got so far, but as i said then i drew a blank, and i may be going about this completely wrong:Dim SQLcon As New SqlConnection("server=DEVSERVERDEVSQL;" & _
"integrated security=sspi;database=WDA_SQL")
Dim SQLqry As New SqlCommand("SELECT * FROM Users WHERE (Username = @Username) AND (Password = @Password)", SQLcon)
SQLqry.Parameters.AddWithValue("@Username", UsernameTSlbl.Text)
