I need to know how create a number that increases every time my main form is loaded. This would go in succession. So the first time after putting this code in it would show the number 1. The second time I open my main form it would show a number 2, and so on.
View 2 RepliesI'm writing a program for my algebra students to practice integers.Stuff like....
3-6
-4 + (-5)
3(-4)
-15 � 3
etc.
I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.
In VB if you prompt the user for a number between 1-20, then a word, how do you get a text box to show the word the same number of time as the number selected using loops?... Ex: please select a number: 4 / select a word: cat....the text box should display ::: catcatcatcat ........

Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

I'm thinking maybe I could make a new button based on some settings in the VB thing, but that seems rather inconvenient. I was also wondering if anybody knew how to get the icons from shortcuts or the rest to use those as display pictures. "Victory is difficult to see beyond the devestation incurred in its pursuit."

Hi!
Last time this forum was the most helpful in solving my problems in vb 2005?This time I am writing a "lottery number picking" program. The program randomly picks 7 numbers from 39, with pre defined conditions on the strength of statistical data, and writes the possible combinations in a text file. It works fine, BUT- the program generates number of combinations I tell it to generate. With other words it works like
For i = 0 to 1000
generate_number()
Next i
So this way I get 1000 combinations. how can I make the program generate all the possible combinations by itself?For example:
Do while (not reached the last combination)
generate_number()
Loop
While I don't know exactly how many combinations there are, I have a slight problem knowing which the "last" combination is.
How would i get the primary key id number from a Table WITHOUT making a second trip to the database in LINQ To SQL?
right now, i submit the data to a table, and make another trip to figure out what id was assigned to the new field (in an auto increment id field). I want to do this in LINQ To SQL and not in Raw SQL (I no longer use Raw SQL).
also, seond part of my question is: i am always careful to know the id of a user thats online because i'd rather call their information in various tables using their id as opposed to using a guid or a username, which are all long strings... i do this because i think that SQL Server doing a numeric compare is much (tentative use of the word 'much') more efficient than doing a username (string) or even a guid (very long string) compare.
im making a random number guessing game type thing, i have the main thing done, but I was just wondering, how could I get it to show the integer rndnumber in the message box that comes up?

View 15 RepliesI have a form (FRMQUESTIONNAIRE). It contains, a listview table, a panel and picturebox, 2 combobox, 10 questions with 5 radio buttons each question ( A survey),A log number id (I just used Label in here) and 2 buttons ( save and skip).
Problem: When I click one item in listview table, the picture captured realted to the item click in listview table will be shown in panel beside it. However, the problem start to happen when the log ID is not appear accordingly based on user selection on listview table.
What I reckon start of the problem: - Previously The listview table(listview1) in frmquestionnaire was in frmqlist(another form). But to suit user requirement, it has to combined with frmquestionnaire. In frmqlist, I use a label Image. This form contains the similar details in frmquestionanire except there are no 2 combobox, 10 questions with 5 radio buttons each question ( A survey),A log number id (I just used Label in here) and 2 buttons ( save and skip) But it have a button(Proceed to survey). Having said that, when user click an item in listview(Frmqlist), the picture will be shown beside it. User will click button proceed to survey and frmquestionnaire will pop up. Here, It shows the correct Log ID based on user selection in frmqlist.
But now....
I have combine everything in frmquestionnaire. I am facing as the LOG ID is not showing according to the selection. As a result, I can't save the questionnaire answer as well as this log will be used to save in database.
