How To Sort Number Correct In A DataGridVeiw
Oct 13, 2011
I have an DataGridWeiw as an result table for a little racing game.The grid is sorting itself everytime a new value is added in a "points" column using the following code. TableDG.Sort(Column2, System.ComponentModel.ListSortDirection.Descending)
And it works fine as long as "points" not exeed 9. eg: I want the datagrid to sort "10" or above as greater than 9. Not putting the "10" or above last in the list?How can i do that?
And is there any way to get rid of the "grey" marked first row?

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

Basically what's happening is that the XML nodes themselves aren't changing position. So I figured my XSLT was missing something.[code]...

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 am exporting a datagridveiw to excel, this works fine. As of now there are columns and headers that i needed to add to the excel data that did not exist in the datagridveiw. This also works fine, the data is held in cells a2:f2, now i want to take this data in these columns and filldown to the last filled row of the excel sheet. In this example lets say i have 49 rows of information, i want to take a2:f2 and copy it down to the 49 row of the excel form. Below is the entire code of the export process, i have noted where i need this code to go with , i am not sure if i should just use a for loop, which i have tried to no avail.

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.

I am having issues getting my application to display the correct number of asterisks per store. Also, I cannot figure out how to get each store to display in the list box.
' BarChart: Chapter 5 #6
' Program Discription: This application prompts the user to enter today's sales
' for five stores. The program then displays a bar graph comparing each store's
' sales. The bar graph is made up of asterisks in a list box. Each asterisk
' represents $100 in sales.

Ok here goes my stab in the dark again: I would like to be able to insert a number in to a list box in the correct order, at the moment the number gets put at the end, but the list box starts negative and then gets larger and the values that will be added are within the range already there, My guess would be some sort of sort function?
listbox1.items.add"inorder"(textbox1.text)orlistbox1.items.sort.add(textbox1.text)
i have seen addrange as a function. can you also tell me if i am starting to think like a VB ((novice) programmer?

I've created code that generates a random number and validates the users guess to see if its correct. I think the code is good but i'm not 100% sure. I need to add additional pieces to the code and i'm not sure where or how to do it. allow the user 10 guesses. after 10 guesses disable the ability to make more guesses if the 10th guess is wrong count each guess entered & display the count as it increments display each guess along with its returned messaeg into a list box. when the user gets correct answer provide a box to allow them to play again. Re-initialize variables back to their starting status.
a. If the user correctly guesses the number in less than 5 guesses display "Either you know the secret or you got lucky!" in a message box. b. If the user correctly guesses the number in 5, 6, or 7 guesses, display "Ah Ha! Do you know the secret?" in a message box. c. If the number of guesses is 8 to 10, then display "Try to do better next time." d. If the number of guesses exceeds 10, then display "You have taken too many guesses."

I've got a number of columns the user can sort by (Name, County, Active) and that's easy but messy. Looks something like this...
Select Case e.SortExpression
Case "Name"
If (isDescending) Then
[CODE]...
What I would LIKE to do, is something more ... like this
Private Function SortThatList(ByVal listOfStuff As List(Of Stuff), ByVal isDescending As Boolean, ByVal expression As Func(Of Stuff)) As List(Of Stuff)
If (isDescending) Then
[CODE]...
But it doesn't like the datatype (Of TKey) ... I've tired Func(Of stuff, boolean) (got something in c# that works nicely like that) but can't seem to get this one to do what I want.What's the magic syntax?

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.
