Show An Explanation And For The Addition And Subtraction - Show It On A Number Line

Mar 7, 2010

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.

Calculator - 2 Textboxes Where The 2 Numbers (or Values Go For Addition And Subtraction)

Aug 12, 2011

I have made my calculator and it has 2 textboxes where the 2 numbers (or values go for addition and subtraction) are input and a label where the answer appears. There is other things on the page such as quit, clear etc thats all done but i have one query. I noticed while testing a problem occurs when only one number or value is put into a textbox and a command is hit. For example. one textbox (txtnumber1) has one number in it then i hit multiply and it says the error of course because its not programmed to deal with this (or divide by 0 of course) so i was wondering how i could make so when this happens a MsgBox appears saying a value must be in both boxes or when divded by zero is says something similar.

The line of code:

Private Sub blah blah blah...

If txtnumber1.Text = False Then MsgBox("Please Input Valid Value")

End Sub

I however have not been able to make it work.

Unable To Show Correct Log Id Number?

Feb 15, 2011

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.
