2010- Sorting A Set Of Labels Against The Previous Set In Order To Check The Answer And Accuracy?
Apr 23, 2012
I have a program which is made with 12 labels, the first set of six are randomly generated and the second set are values obtained from the first set and the user has to choose in ascending order the numbers on the first set.The values chosen will be trasferred to the second set and then with a "check" button that set of labels have to be rearranged and compared to the user input.If the user for example manage to choose the right order, he will obtained a 6 of 6 and he will recieve a message.My problem is on the rearrage and compare part.
The code I made is very simple but is not working, basically it only check if the next value is smaller that the previous and changed its back color according to the case.
Here the code:
'check button
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim Score As Integer
Score = 1
[code]....
I would like to have a correct rearrange of the numbers and introduce a message according to the accuracy of the user.

I have a list of strings lets say the items are like this:
item_1
item_2
item_4
item_10
item_8
item_11
If I do list.sort() I get the following
item_1
item_10
item_11
item_2
item_4
item_8
Somehow I need to get these in order numerically but I am dealing with strings not numbers.

i have a windows form application with a textbox and 2 listboxes on it. The program is designed where i type in a filename in the textbox and the contents of the file appear in the listboxes. In the the first listbox the names of the students and their grades appear in the listbox. In the second listbox each of the students last name and their overall grade appear in the listbox. What i need now is a sorting algorithm that will sort the students to appear in descending order so the the student with the highest grade will appear first and the student with the lowest grade will appear last.

This is similar to How to keep the order of elements in hashtable, except for .NET. Is there any Hashtable or Dictionary in .NET that allows you to access it's .Index property for the entry in the order in which it was added to the collection?

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

I'm writing a financial calculator. I know that my calculations are more precise when Decimal format is used. But when I calculate 314/365, the answer given by VB is 0.8602814581, where as the real answer is 0.8602739726. This ends up affecting my calculations quite a bit.

I have a form that has a large number of labels. Is there a way I can move the focus from label to label. After I move the focus I'll check if the name of the label has a certain string in it. If it does then I'll leave the focus at that label. If it doesn't I'll move the focus to the next label and check if that label name has the string in it. I just need to know how to move the focus from label to label. I was trying SelectNextControl without success. Maybe I can tab programmatically to the next label but I don't know how to do that.

I recently started wondering about how Microsoft would go about checking the text and checking its color, word order (spell check), etc. and I was trying to think of how they would do it if they were forced to write something, like Word or the text editor in Visual Studio, in Visual Basic.NET. Ways that I thought of could be using an array, setting a string to a word in that array, and check if that word is in the text. However, after I tried it, I realized I had to set the .SelectionStart property to zero, which got annoying if the document was long. Also, with arrays, though I could store the strings in a text file and read from that, I was limited to the number of items I could have, and I'm sure it would get frustrating if I added or subtracted a word (then having to back in the code and replace all of the instances of that array.)
Then I started thinking about streams. Though I have not tried them yet, I would imagine that if they had to be used, the problem of speed would come up again. But what if the stream only checked say 30 characters before and after the current selection start? Well, that would solve the speed problem, but it would bring up another. Every time the caret position changed, (if we were checking for color changing) we would be limited to those 60 characters. Say the word is "hello". What if "hello" began 31 characters behind the current SelectionStart? "h" would remain the same color, but "ello" would turn the default color (this is because we would have to reset the color everytime just in case the user changed a certain word.)
