View 7 RepliesI'd like to know how to sort an array that has entries with numbers after text.
I have a list of four entries:

I am new to using VB2010 (and coding in general). Also brand new to these forums . Okay so I am making a program that: allows the user enter the number of customers served for each of 12 months into an array. The application should calculate and display the following statistics: total number of customers for the year, the average monthly number of customers, and the months with the highest and lowest numbers of customers. Use inputBox to get user input. Do not accept non-numeric or negative numbers.
The problem that I am having is that I do not know how to display which was the best and worst month. I imagine I need something that targets the highest/lowest number and finds the text in the corresponding index but I'm not sure how to do this.
I don't know if I worded this properly, but I have a mdb query that I display in a Datagrid on my form. The first column is TransactionNumber, which is the primary key and a running total (ex. RackingTransactionKey=RackingTransactionKey + 1). What I need to do is when the form is opened, find the highest (last) TransactionNumber from the query or Datagrid and assign it to a variable (RackingTransactionKey), so I can can update it (+1), therefore generating a unique number so I can add data to the query.

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
I got 2 LABELS and ONE BUTTON... when i press the button, it fills both labels with a random number from 1 - 6.ild like to do it like this... you press the button then a little prograss bar starts running for 3 or 4 seconds... and THEN after it reached the bars max i want it to show the numbers in the Labels...
the second thing is...i want to make 2 checkboxes next to the labels... if you mark the first checkbox, next to the first label... and the outcome is that the number of the first label is BIGGER then the other one.. you should get some kind of a msgbox.. i know how to make a msg box... but i dont know the code for vb to check if label1 is > or < than label2....
