Date Comparison Not Returning Correct Results?
Mar 5, 2011
I am pulling a date value from my database:
Dim qfresho = From p In dbConfig.Configs _
Where p.Description = "FROD" _
Select p.dateValue
Dim qfreshc = From p In dbConfig.Configs _
Where p.Description = "FRCD" _
Select p.dateValue
Then comparing these date values to the current date:
[Code] .....
But for some reason its always returning the Else condition - even though the values in the database should make the query true. I'm guessing for some reason its not pulling the results as a date?

Ok simply my code doesnt want to output the correct number. I'm working on the project euler probems to expand my knowledge in VB.net and the current question I am working on is asking to work with triangle numbers. while researching I found that a triangle number can be calculated by using the formula:

I have a filtered bindingsource bound to a datagrid. The datagrid fills and displays the data correctly based on the filter criteria.
The problem comes when I try to access the data directly from the program. It returns data, but only as if the filter wasn't there at all. [code]...

I have a DataSet where I need to filter the collection where one of the date columns is not null.
How do you term this in LINQ?
This is what I have so far but there is a compiler error on the w.CompletedDate field in the Where clause.
Dim completed = From ins In InspectionDataset.Inspection.AsEnumerable _
Where (Function(w) w.CompletedDate IsNot Nothing) _
Order By ins.Field(Of DateTime)("UpdatedDate")
I have also tried it the below way but the compiler will not allow the DBNull comparison.
Dim completed = From ins In Inspection.AsEnumerable _
Where ins.Field(Of DateTime)("CompletedDate") <> DBNull.Value _
Order By ins.Field(Of DateTime)("UpdatedDate")

I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.Current Occupancy < Max Occupancy Available Flag is Checked I know this should return results but it keeps returning an empty set.Code is below
[code]...
UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.

We are noticing this occurs BOTH in javascript and in VB.net 2.0. So basically both in server side and client side code. Basically if you run this equation 975328 - 153279.43 you get the following answer 822048.57000000007. However, if you run 975328 - 153279.4, 975328 - 153279.433, or 975328 - 153279.5 everything is returned correctly. WHY the system calcuates the 975328 - 153279.43 with an answer with 11 decimal places? Not to mention adding the 7 in the 11th decimal place, thus making the equation answer incorrect.Of course I know I can trim, set the answer to appropiate decimal places, etc., etc.the above is proven by just entering the equation into the immidiate window, thus ellimnating varibables such as object types, etc., etc.

I'm doing some XLINQ in VB for work. I basically need to pull some values from a small chunk of XML as listed here:
<?xml version="1.0" encoding="utf-8"?>
<Fields>
<typeQtyRadioButtonList>1</typeQtyRadioButtonList>
<cmbQtyCheck>Reject</cmbQtyCheck>
[code]....
... Leaving out the implementation of the For Each loop....So I have stuck a break point on the for each and the collection has no elements in it.

I'm working in visual studio 2005 and developing a windows form that has a datagridview on it.
One of the cells is a Calendar Column type (custom made). I pulled the code for it off the internet - it basically allows the user to select the date from a small calendar.
When the date is changed, it gets the correct value and it also saves into the database with the correct value.
The problem is that it doesn't load onto the grid with the correct value. In fact, no matter what date I enter in, it always displays it as 1 day earlier. e.g. If I saved it to the database as 4/19/2012, it displays it as 4/18/2012.
I verified that there's no other column in the query that retrieves the data for the grid that contains the value it's displaying.

I have been having an issue with returning records from a SQLServer database where the date the record was created is between 2 user specified dates. When I populate the DataGridView with the results, they are incorrect and do not follow any recognisable pattern.
For example, if I specify the dates 05/05/2010 and 12/05/2010 I get the attached data in the DataGridView.
Code:
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
'Clear the DataGridView

I have a GridView which is showing results and from which I am deleting a result using the auto-created delete link. My code behind to remove the row and associated info. is:
Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
' The deletion of the individual row is automatically handled by the GridView.
Dim dbDelete As New pbu_housingEntities
' Remove individual from the bed.

It seems that it is not able to grab the row that is being deleted, so it is always giving me a "Object reference not set to an instance of an object" error.

Im currently working on an n-layer application that does alot of database work.90% of all database queries are updates, and inserts and I want to be able to view the results of my query in the presentation layer.I was thinking of creating a QueryResult class that has a few properties like QuerySuccessful (boolean), Message (string) - holds success or error message, and optional field to hold any additional data that may need to be passed back to the presentation layer.So I guess my question is, am I going about this the correct way by creating a QueryResult class, and passing that back up through the layers to my PL?

I have a problem which I have tried to solve in several ways, and by searching the Internet for various terms, searching through books and Visual Basic instructional videos, but none have yielded the correct results. My goal is as follows:
1. Create a Database listing job names, job numbers, and a link to the file about the job.
2. Create a form with 2 text boxes, a search button, a box to display results, and a preview panel.
The two above steps have been completed. The following is where I get stuck
3. I want to search for either the job name, and/or the job number, have VB search through the database and return the results in the results box.
4. On clicking on one of the results in the result box, the preview panel will show a preview of the file.
Notes:
i) The files being linked top are Microsoft Excel files.
ii) The box I have used for the results currently is a listbox, though I've no idea if this is the correct choice for what I want to do.
iii) The database I created is an *.xml database created in Visual Basic. I am a fair beginner to VB, learning as I go, but I'm stumped as to how to achieve this so any pointers on how to achieve points 3 or 4

I have been taking a class in Visual Basic and am currently working on my final project which I am having some trouble with. I am using Visual Basic 2010 express The project is to create an application that will store data in a text file, specifically, Last Name, First Name, Customer Number, Address, City, State, ZIP Code, Telephone Number, Account Balance, and Date of Last Payment. I have gotten everything done except the ability to search the file by Last Name or Customer Number. I have no idea how to go about this? I was thinking of ways to use indexof or Readline to be able to search the data, but I'm not familiar enough with the code to come up with a good solution. Below is a picture of how my form looks..As you can see, I'm currently using 2 separate forms to get the data from the user. Here is the code for Form1 which is the "Customer Accounts" form in the picture.
Imports System.IO
Public Class Form1
Public customerFile As StreamWriter ' Object variable
Public customerFile1 As StreamReader ' Object variable
Public strFile As String
[Code]...
There isn't enough room to post the code for my secondary form, but you get the idea. I would like to be able to enter a search term in the textbox on the bottom right of the form, and either search the data as its displayed in the listbox, or search the actual file? I was thinking that the results would be displayed in a messagebox?

I have a Search web reference (from a Search Server 2010 express install) in a vb.net application that is utilizing the QueryService Class to search a production Sharepoint foundation 2010 site.At a previous point in time, we had created a proof of concept on an entirely test system that has since been turfed. From my recollection on this test system when documents were uploaded as a specific site content type (that inherits from document) and metadata was provided, we could search for specific metadata by making managed properties for each, and search results would be returned as documents (with the isdocument flag set to true). Viewing the document then became simple, as we could simply use the filename and path to display the stored file.Now we are developing a production system and we have encountered a new behavior, where these results now are returned as aspx results such as
[URL]
This of course makes it terribly difficult to locate and view the document, we can extract the Title which will then give us the name of the file with no extension, but that hardly helps, as the FileExtension data is aspx, not the documents file extension, so we don't have a full filename. We could display the page returned as a result, but would much prefer the document itself.
I've made a test document library, with just bare bones setup, (not using the site content type, or site columns) and uploaded some documents on the same site, and they are returned in the same fashion, so I don't believe the document library, or content type are the issue.
With a fairly limited understanding of both Sharepoint and Search Server, I don't know if this is a setup issue with the search service itself, with the site configuration, or with the querypacket I am sending. We also have a third party application (Knowledgelake) installed on the server that ties into sharepoint which could have changed configuration somewhere as well?
I don't think the query packet has changed since it was working in the proof of concept, other than the custom data column names. I will provide it here in case there is something glaringly obvious to an external reader.
<QueryPacket xmlns='urn:Microsoft.Search.Query.Document'>"
<Query>
<SupportedFormats>
<Format>urn:Microsoft.Search.Response</Format>

I am working on a business related program, so I need to know if system date is correct -synced- with remote server. How do you do that in vb .NET winforms?
P.S: In addition, is there any way to raise some event when system clock changed to prevent hacks? I don't want users to change local date after logging in their account.

I need to return the exact difference between two dates in the form of a string. If the dates are 01-FEB-2012 and 01-FEB-2014, the function should return "2 years" If the dates are 01-FEB-2012 and 01-MAR-2014, the function should return "25 months". If the difference is not in exact years or months, it should return the difference in days. I do not want to use DateDiff from the Visual Basic namespace so the code is portable to C#.

not like this 2009/02/02
not like this 02/Jun/2015
not like this 02/abc/2010

Private Sub txtHireDate_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtHireDate.Validated
Dim dateString As String = txtHireDate.Text
Dim formats As String = "MM/dd/yyyy"

I have an SQL Database which has some end dates. I have used this little statement to make sure that the dates come out of the database in the right format
Execute("Set dateformat dmy")
And I use the below statement to enter the data in to a datatable and, with the above command, when I go to look at the data in datatable visualiser the dates seem to be in the correct dd/MM/yyyy format
"SELECT CID, expdate FROM Traineecerts WHERE iscurrent = 1"
Now when i try d1 = row("expdate") the format changes to the american MM/dd/yyyy format
Please note d1 refers to a variable with the type of date. Even if I format the dates after using d1 = format(row("expdate"),"dd/MM/yyyy") they don't change unless I make d1 a string. Is this normal?
