I'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 ........
I am doing this for a class and my brain has locked up. Prob. just over thinking it though. Thanks in advance for any help!
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.
I wrote a function to format numbers like this: 123456100,12 -> 123.456.100,12 (I have a function too, which converts numbers from this strings).Now, I have a dgv and a column with these numbers (or rather strings). The sort mode is set to automatic. If I sort the column, it doesn't work, because the values are not really numbers, but strings. But I get the same result (the sorting doesn't work), if I use the formatnumber function (this returns strings too).
I could use the programmatic sort mode and before sorting I format the strings to numbers, then sort the column, and then format the numbers like above. But this is a bit slow (the dgv has appr. 800 rows), and in this case, I haven't an arrow next to the column header text.is it possible to sort the column like a normal number-column with automatic sortmode?
I have form 1 (User Details) and form 2 (Transport Usage). Now in form 1 there is a textbox which shows the user's ID and when i click a button that links form 1 (user details) to form 2 (transport usage) i want another textbox in form 2 to have the same user ID as in form 1. (the user ID always changes)

is it possible to make something that can show the number of active applications? For example some code that say: Label1.Text = Number of running applications
I 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.
Does anyone have a 1 to n thread example in which n threads are created dynamically? There are a number of examples that show a definite number of threads, and some that imply n threads by using a tcp ip listener or a file system listener. However, I'm looking for a 1 to n created in response to a dynamic requirements, provided purely by and for my program.Essentially, my requirement is to be scalable. 1 to n threads based on application throughput should make this pretty easy to satisfy.
so below is my code. I am trying to get the autonumber generated in newdb into txtcallid field. the error i get is that the field is not unique. What i am trying to do is to get the form to fill the db witha new blank record, assign the auto number and then display that number with the blank record info in my form. I will be making it so that the data must be changed before saving so that the form will not be blank save for when it is loaded.
