Program That Will Go To A Web Site And Pull Out A Specific Piece Of Data
Jan 19, 2011
I want to build a VB program that will go to a web site and pull out a specific piece of data.I am using VB Express 2010 not sure if it belongs in this .net forum.I am successfully getting to the website using WebBrowser.navigate()The data is provided to me in XML format and I am told that it is ready to be retrieved. They tell me to use XML Parser.When I go to their web site I see the data I need to pull out there is a column with tags in front of each piece, the piece I need is between <Vr0> and </Vr0>.I have no resources other than the net currently I do have a dummies book ordered but will be at least next week (at the earliest) before my first book arrives.Can you explain how I can sort through the data and pull out the data in XML format on a web site?
I'm basically trying to do a small report card project. I only need to pull 5 Students with each student having 5 Test Scores a piece. The full Code of what I have for the submit button is below. I have actually 3 questions.
1. I always seem to have trouble with them unless I initialize them when I dim them. Is there a better way than below
2. The below code works really well for Student 1 and all 5 test scores. Rather than do that code 5 times though, what is the best way for me to basically state that IF dblStudent1(intMax) = 4 Then Change dblStudent1(intMax) to dblStudent2(intMax) etc.
3. Would this be better suited towards a multidimensional array ?
Private Sub btnEnterGrades_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterGrades.Click
Dim strStudentNames() As String = {" ", " ", " ", " ", " "} ' Holds the 5 Students Names Dim intMax As Integer = (4) ' Place Holder for Student Number
I am trying to work with an access database. If this line pulls data from a dataset and puts it into a textbox: TextBox1.Text = Me.A_DataSet.a_Table.Rows(0).Item(0).ToString How would I pull the field name? For Example, in this database I have 3 fields:
I would like to search a webpage for a value in the left column of a table, then pull the value from the right column as my result. In a Visual Basic Forms Application.
the data is listed in a table, for example...
abc 123 def 234 ghi 345 jkl 456
and if i just want the value of ghi ( I know "ghi", but i want the goal of the code to find the "345")
When i publish my program i choose to let the application check for updates via a website and if their is one update automatically when the program starts. Is their a way were on the main user form i can make it so that the user can change the update site with out me building the program again with the new site. I want to do this becuase the site i use goes down alot so when i changed the update url no one was able to download the update for the new update server.
my situation is this; I have a search button which searches records with Surnames, when two or more records have the same surname, the first record appears and 4 navigational buttons appear, they are 'Go back to first record' (btnFirst), 'go back one' (btnPrevious), 'go forward one' (btnNext) and 'go to the last one (btnLast)'. All of these work properly except for 'go back one' (btnPrevious). When I click this and the record is currently the first one, the program crashes. Its probably a very elementary mistake but I can't figure it out. Here is the code for btnPrevious
Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
Public Class Form1 Dim word Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
How can i get the value accumulated from the date i select from datetimepicker1 to datetimepicker2 in vb.net and mysql? the value here refers to the daily sales and i need to find the total sales between the range dates that i choose..
I am trying to import a text file into a data table using VB.NET. I need to loop thru each line of the text file and put certain elements of that line in a new row of the data table. The line may contain 50 elements, but I only need to get 15 of them. The very first line is a header row, which contains "File Name", "Object Name", "Object Weight", etc. The trick is the element locations move from file to file. For example, "File Name" element may be located at 0 in one file and then 15 in the next file. I need to find the exact location of my desired elements and save them to a variable. Then use that variable to locate the exact piece of data in the text file line to place in my new row.
The code below obviously doesn't work, but it kind of illustrates what I need to have done.
Try With dt .Columns.Add("fltObjectWeight", Type.GetType("System.Double")) .Columns.Add("vchObjectName", Type.GetType("System.String"))

I have a database called "IMYS" and a "Customers" table in it. What I want to do is: Define a variable like "Last_Name" and retrieve last names of customers one by one. I've tried this before (and, it doesn't work for me):

I have two comboboxes and a listBox to display data from several databases. The whole process should be that after an option is selected in the first comboBox, the second comboBox and the listBox are populated. So for example, I could select a Company from the first comboBox, and the second conboBox will be populated with all it's locations while the listBox will first display the location of the headquarters(default location). But the user can then select a different location from the second comboBox if they want to and the listBox will then display the location of that newly selected office location.how do I dynamically pull these data from various databases cause all the companies will have their information in separate DB's. My challenge is how to dynamically pull these data from the various DB's to populate these 3 controls.
My program pulls a weeks worth of records at a time and filters it into daily columns on a form, the problem is that there are ~80 fields to be filled in this manner and as far as i know each one has to be check for null before it can be filled. Could someone tell me if there is a faster way to do this? Below is my current code for one set of fields.
Private Sub cboDigit_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboDigit.SelectedIndexChanged, cboOffice.SelectedIndexChanged, dtEndDate.ValueChanged, dtStartDate.ValueChanged

I'm having a problem to pull data from MS Access to my combobox. I know how to search one data using another data (e.g: using IC num to search name) but this time I just want to pull the data (e.g: name) that has several rows to my combobox. I think the method is the same but don't know where to change it.
Then when I added new names to the combobox, want to save it to my database, can each name be saved in different rows? I added the names to the combobox 1st, after that then I saved it. [code]...
