I have a listbox displaying sql results in a loop. Let's say I want to select one of those results and click a delete button. I have the button and box setup displaying the results just fine, I just do not have the functionality. How would I do that?
View 18 RepliesI'm making a program when the user clicks the button it displays the number of rolls it took to get snake eyes ( 1 on each dice) I have randomized it and in the Do loop it calculates until it gets the right code. I just need some help with the code that will display in a listbox the results that didn't get picked for snake eyes.

I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code. I have tried to adapt the code I had to insert data into my database, just changing the SQL sintaxa and some other bits, but it is not working yet. Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:
Public Class Form2
Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click
Dim str_search As String = txt_search.Text
Dim str_dob As String = txt_dob.Text

I am writing a VB.NET Windows Application which takes numeric user-input and performs a complicated calculation, yielding many numeric output variables. Previously, I wrote a similar program in VB6, which output the results to a rich text box using fixed-width font in order to organize data in columns and used asterisks to delineate table areas and section borders. I then used the printer object for printing the output. This method was very archaic and difficult to modify when changes were necessary.

which usually contains: 4 so when i loop out the names, it loops the 4 results, 4 times, instead of just showing me the names 4 times so i can then store them

So that works, but how do I display multiple things, CustomerID & CustomerName on the same line?
I can't get it going, it only puts my CustomerName under the ID
So, I'm working on a custom LitBox that accepts custom items. needed the item collection to be more than just strings, I needed to be able to store avalue to display in the listbox and an associated value (Property: Text) that holds an index value (Property: Tag) of DataTable I'm working with.I have created the new item (iListBoxItem) and the collection (iListBoxItemCollection) and have modified everything so that I can do normal Collection type methods (Add, InsertAt, RemoveAt, etc) to this collection.

I am building an application that will run through various tasks like database backup, zipping some other files and so on.I have the progress bar figured out for each individual task and I have all my tasks working.I am trying to build an interface to display to the user to show them the progress of the entire run.I was thinking like a list box or other object where I could put a green checkbox image or red x image as each tasks runs and is a success or failure.
View 1 Repliesi'm working with a sql (2005) database and using visual studio 2010. I've created a system where one of the forms is a find/search form. A user can enter in for example, a customerID and once they click on "find/search" the customerID will be searched in the database and if found, all relevant information about the customer will be retrieved and displayed in another form (find/search results page). I realise that this can be done using an SQL statement like follows
searchStr = "SELECT * FROM Customer WHERE CustomerID LIKE CIDTextBox.Text%"
What i'm unsure about is how to execute this SQL statement once the "find/search" button has been clicked and how to display the founded results in another form.
So I have coded connection to database and query but when I push button nothing happens. So my question is how can I fix that Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have to write a program that allows a user to input DVD info such as DVD Name, Year produced, Running Time, and Rating. The user then clicks a menu item "New" to save that info to a file. Then the next time the user inputs new DVD info it has to append the new data to the same file. (I got this far and everything is working writing and appending data)Next the year has to be able to search by DVD Video name and it has to print the info in the text boxes on the form, if not found then a messagebox should say not found. When I use the sub procedure that I have created to search the record it always comes back as record not found although the record in in the file.

The assignment called for a VB.Net (not web based) program that would accept user input for the loan amount, interest rate, and term of loan, and display the monthly payment of the loan then list the loan balance and interest paid over the term of the loan. the list will be longer than the screen so use loops to display a partial list, hesitate, and then display more of the list. So, I did exactly that and the program works fine. However, after submitting this program for grading, The instructor for the class tells me, "One thing you should work on is not using a timer to pause.
You should not use a scroll bar either." He says I should work on loading the results into an array or use a loop with a counter that can be used to display a given number of results with a more results button for displaying more (but without a scroll bar?). Like I said, this program works fine and I am not asking anyone for any specific code (some sort of example would be great but not necessary) What I am asking for is an explanation of how I would go about loading results into an array to be used for displaying just partial results at a time in some way other than I used here: [Code]

I am currently having a headache on how to solve this problem that i am facing.here is the situation:I have a combobox and a list box on the main form. The combobox will get the data from the ms access database.In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987
So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown.
