Extracting A Range Of Data For Time?
Apr 12, 2012
I am looking to pull a specific time of data from my sql Data Base, Is this correct or is there a different way to do it?
Dim sqlShift As String = "SELECT * FROM ShiftTasks WHERE Shift=@Shift, Time>=@Time1 and Time<=@Time2 ORDER BY [Shift], [Time], [Priority] DESC"
Using Con As New SqlConnection(ConnectionString)
[code]....
I found it, Needed to replace the , in the SQLShift String with an and
Dim sqlShift As String = "SELECT * FROM ShiftTasks WHERE Shift=@Shift and Time>=@Time1 and Time<=@Time2 ORDER BY [Shift], [Time], [Priority] DESC"

PUBLT 167_89 656 PB -38321.478 6807.984 657 PB DAUD 200005041 278.271074.5150 69.4035 08370074.1830 69.2755 083800254.1925290.4620083900254.5615291.010008400008390098.2710 74.3630 20.3943

I am exporting data from an sql table to an excel spreadsheet in Visual Studio 2008. There is a field that is date/time that I only need the time part of (hh:mm). I am using the Convert command to do this, but I am getting the error 'Undefined function Convert in your expression'. Is there another function I should be using? Or am I missing and Import command at the top?Here is the code (field TimeofFall is the one I am having trouble with):

We have a Try/Catch block of code in our web application to trap a certain exception. What we want to do with this exception depends on the current time. If it is between 4:30PM and 3:00AM we will want to send an email, otherwise we will throw the exception.

Here is what I did.
1. Went to data source window and clicked "add new data connection"
2. Choose Data Base clicked next
3. Clicked Create Typed UserInformation as the name
4. Next.... Under Data set name I typed UserInformation again
Does naming the database and the data set the same cause problems?
5. Created New Table called users for UserInformation Database.
6. I added the following Columns: FirstName, LastName, Address, and Phone
7. Edited the table to add a couple of people. Tom/Franks/108 blah street/5555555 and Bill/West/109 blah street/5555555.
8. I also reconfigured the data connection in the data source window to show the users table.
I have four labels on my form, a text box, and a button.
I want to be able to search the database by last name for what the user typed into the textbox when they click the button.
I know this is probably easy for all of you but I am still trying to get used to using databases.

I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work. When the application is run, the .txt file is created, but is blank and I get a pop-up that shows the following, "trying to access email in outlook do you want to allow this?". The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.

Im trying to extract predominately table data from a PDF file, however, I would also like the option to extract image files (such as graphs, etc) as well.Is it possible to extract data from PDF files using a VB.Net application? Im trying to get this process as automated as possible, so Im trying not to use 3rd party applications such as pdf file convertors or in-line pdf readers.
Are there any free, or relatively cheap PDF data capture API's/code snipets that I can use to import data from a PDF file? Another option is to export PDF data/images into an excel spreadsheet. Is there a .Net tool that will allow this?

All I've been able to do is create the form. We have to get information off of a website and load certain information back into the textboxes on our form.
Assignment 6 - Text Parsing Many applications require you to extract information from a block of text. We will be using this heavily in the project. This project is designed to give you some practice extracting information out of text files. You will need to open up a file, search the file for some specific content, and then copy that content and place it on screen.
Go to Jobs.com and select a state that starts with the same letter as your last name (if there is no state that starts with the same letter, use the second letter, then the third letter, etc.). For example if my name was 'John Byway', since there was no B or Y, I would pick a state starting with W - either Washington, West Virginia, Wisconsin, or Wyoming.
The idea is you want to extract all the jobs information out of the page. We want to put the jobs names in a combo box, so the use can pick any of the jobs. Ideally, this would also show the information about each job. You don't need to do that. However, you do need to extract the information and put it on the screen (When you load the next job, the old job information will be lost, and you will be left with the information about the last job loaded)
Tasks
1. Go to the above address, view the source in the browser, copy and paste it into a text file. You do not need to access the Source of the web page within your application.(in IE go to View / Source; In FireFox go to View / Page Source)
3. Extract each job title and place the name in the Combo box.
4. Find and extract the following fields. Note, some jobs may not list all of these. In that case, get as many as are presented.
a. Date
b. Title of job
c. Company
d. Location
[code].....
Indicate on screen how many jobs you found. Note, you only need to look on the first page of jobs?

I have a .trx file (a unit test result file) which is just xml inside and I want to read the file compare a few of the tags and change them as necessary and save the file again.
I found that VB.NET has a few tools to help so the first thing I do is load the document into an xml document which seems to work fine but I can't access any of the data I need. Right now I'm trying to access the attributes of the counters tag and change them after rerunning some of the tests.
this loads the file:
Dim Doc As XmlDocument = New XmlDocument
Doc.load("testFile.trx")

I have a csv file with 48 columns of data. I need to open this file, place it into a data structure and then search that data and present it in a DataRepeater. So far I have successfully used CSVReader to extract the data and bind it to myDataRepeater. However I am now struggling to place the data in a table so that I can filter the results. I do not want to use SQL or any other database.
So far, this is working in returning all records:
Private Sub BindCsv()
' open the file "data.csv" which is a CSV file with headers"
Dim dirInfo As New DirectoryInfo(Server.MapPath("~/ftp/"))
Dim fileLocation As String = dirInfo.ToString & "data.txt"
