Alpha Numeric Sorting For Binded DataGridView?

Mar 27, 2012I have a vb.net application successfully processing the text in TIF files, but it is ignoring the checkboxes.

Get The App To Accept Numeric And Operator Input While Ignoring All The Alpha Input?
May 10, 2010I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then
Select Case e.KeyCode

I can't get vb to recognize the above code it seems to skip right over it. BTW, is 'Keys.Crsel' the same as the caret '^' symbol?
Numeric Sorting A Datagridview?

View 3 RepliesBound Datagridview Sorting With Numeric Data
Jun 28, 2009I am a programmer from Uruguay. I have read the other similar questions about my problem, but nobody has given the answer I need. I use VB .net 2005 and its datagridview. I bind it to a dataset which is populated with a table of MySql. And when I sort the numeric columns, it sorts them as string, not numbers. I have tried casting the data to integer in the sql statement, but it doesn`t work. I changed the format of the column of the datagridview to single or long but it didn't worked either. I really can't believe it is happening, it is a so common need! I thingk It should be totally automatic.

View 3 RepliesSorting - Combobox - Auto-complete Behavior For Numeric Values?
Feb 21, 2012I have a problem with the auto-complete behaviour of comboboxes in VB.NET (with the .NET framework 2.0).I am using a combobox to type in numeric values, and its DropDown list to suggest possible numeric values. This list is sorted in ascending order, for example {"10","92", "9000", "9001"}.The combobox properties are set as follow:
AutoCompleteMode: SuggestAppend
AutoCompleteSource: ListItems
DropDownStyle: DropDown
Sorted: False
The DropDown list is simply filled like this:
myCombobox.Items.Add("10")
myCombobox.Items.Add("92")
myCombobox.Items.Add("9000")
myCombobox.Items.Add("9001")
When I don't type anything, the order of values of the DropDown list is correct, in original/ascending order. However, when I start typing something, the suggested values in the DropDown list get sorted (alphanumerically): if I type "9", the list of suggestions becomes {"9000", "9001", "92"}.I would like to prevent this behaviour to get the values of the list in the original/ascending order. I can't figure out how...A possible work-around would be to pad with zeroes the values in the list, e.g. {"0010", "0092", "9000", "9001"} but I would like to avoid this.

Wpf - Sorting Observable Collection Incorrectly Sorting?
Aug 20, 2011I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.
The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:

Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?
VS 2008 - Storing / Using Numeric Data

I am a beginner but I also have a basic understanding of quite a few program statements and objects. My Goal: For the sake of simplicity I will use an example. I have a Tetris game, the player loses in the first level earns 25 points they click the save score button. , they play again tomorrow and do 1,000 levels and earn 25,000, now their score is 25,025.
Then they play my blackjack game, they gain 25,025 points when they start automatically from their Tetris game, they earn 25 points in blackjack click a save score button, now they have 25,050. [Thus far I have 2 games, and they both share a score that will need to be added to in the future]
