Assume an application uses the Dim SalesArray(1 to 10) As Integer instruction to declare an array named SalesArray. The array contains 10 sales amounts. When the user clicks the DisplayAverage button on the form, he or she should calculate and display the average sales in currency format. The code for the DisplayAverage button doesn't work. Fix it.

View 20 RepliesI am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

View 4 RepliesI am working on an app and I am a bit confused w/ threading. I understand the point of threading but I am not getting when to use a background worker thread vs. a standard thread vs. a thread pool. Can someone shed some light on when to use which? Right now, I am trying code an app that does stuff initially in a sequential order and then eventually must thread (otherwise it takes forever). The problem I am having w/ the sequential stuff (and threading later) is that I need a button to be able to stop execution of code. [Code]
I did the background worker on this first sequential operation because when I tried w/ out it, the text box didn't update at all until the web page contents were retrieved. Basically, the text box change of "Starting." doesn't show up until the web page is finished processing even though the assignment to the text box happens before that code.
Is there any way to stop the execution of the code that's under a button if for example a certain condition is met?

I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
View 12 RepliesI need to pass the values that I generate from SQL queries back to my VB code-behind window so I can apply a bunch of program functions to them. The queries work like a charm, and look something like:
SELECT Max(Number) FROM .dbo[00Masterlist] WHERE (County) = @County
and then in the next screen of the "Configure Data Source" tool I set up the WHERE and all is well.However, this information is only the beginning of my obligation to the project.It will display just fine in any data view I choose, but that's not what I want it for.I want to code with it from there. I've tried setting up the SQL as a string variable in the VB, but it reads the string as a literal set of characters instead of as SQL.I've tried stealing it from the form it prints to in a querystring, but that got really really messy.
Why Wont This Code Work?

I have a form in VB.net. When the applications runs it populates the data on a datagrid from the database. Then I have an export to excel button which when clicked creates a spreadsheet and dumps all the data in it. Nice!!!Now, what I want to do is have another button to auto email the work to my Boss. The work should be presented to him in a spreadsheet form, therefore I reckon after the export will be ideal or any ideas will be handy
View 2 Repliesthis is the second time I have had the same problem come up so maybe some of you have had the same issue. I have a form that has only a text box a list box and a button. The list box is loaded with part numbers from a database, the text box is used to search for a part number and the button is to accept the selected part and close the form.
