Count How Many Times A Certain Item Appears In The DataGridView?

Nov 23, 2011

In my DataGridView, there is a column for names of machines in the database and I want to count how many machines of each time I have. I have set aside 1 text box with 1 label for each time of machine and in the text box, I want to display how many machines of that type are in the DataGridView?For example, I have 50 records and 30 of those records use machine "80ER" while 12 use "90E" and 8 of them are "PM100". I'd like the 80ER text box to show 30, 90E text box to show 12, and PM100 text box to show 8.

Count The Number Of Times That A String Appears In Another String?

Jul 15, 2009

How do I count the number of times that a string appears in another string. I know this code:

If odocument.ToString.Contains("window.alert") Then
pops = pops + 1
End If

But that will just see if the desired string contains "window.Alert" once, rather than how many times it does contain it.

Click Item In DataGridView And Text Appears In Text Box?

Nov 28, 2009

I have a datagridview which is populated with information from a database. I would like it so that when I click on one of the items in the table, the information appears in the text box, or other suitable tool.

The VB output is an EPG (electronic program guide), that has a list of programs and the channels/time etc. So when you click on the program such as 'The News,' the data from the database such as 'Description' will appear in the textbox.

Client That Appears Same Number Of Times As There Are Keywords

Dec 13, 2011

I know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.

Number Of Times A Character Appears In A String?

How can I count the amount of times a character appears in a string?

The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.

I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:

Count Number Of Times A Textbox Was Used?

Apr 10, 2011

This text book i have is not very good at all. the exercise's at the end of each chapter ask u to code projects without first covering the basic of what u will need do to code them. (Programming in Visual Basic 2008 Julia Case Bradley + Aninta C. Millspaugh)

Design and code a project to calculate the amount due and provide a summaray of rentals. All movies rent for $1.00 and all customers receive a %10 discount. The form should contain input for the member number and the number of movies rented. INside a groupbox display the rental amount, the 10 percent discount, and the amount due. inside a second groupbox, display the number of customers served and the total rental income.(afterdiscount).Include buttons for Calculate, clear, print and exit. The clear button clears the information for the current rental but does not clear the sumarry information. A print button allows the user to print the form. Do not allow bad input data to cancel the program; instead display a message to the user.[code]...

Bound ListBox Item Count Changed Event

Feb 22, 2011

I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?
