VS 2008 Bug With E.Keycode On KeyUp Event Handler
Dec 31, 2009I have this code
If e.KeyCode = Keys.D0 Or e.KeyCode = Keys.D1 Or e.KeyCode = Keys.D2 Or e.KeyCode = Keys.D3 Or e.KeyCode = Keys.D4 Or e.KeyCode = Keys.D5 Or e.KeyCode = Keys.D6 Or e.KeyCode = Keys.D7 Or e.KeyCode = Keys.D8 Or e.KeyCode = Keys.D9 Or e.KeyCode = Keys.Oemplus Then
[Code]....
The output WILL be 189 when I press the - sign. But when I check "Keys.OemMinus" it stands for 189 and when I replace "Keys.OemMinus" with 189 it won't work either!
I checked the Resources file and it's correct. The picture just doesnt change, only shows the last pressed button...

Alpha Numeric Sorting For Binded DataGridView?
Dec 9, 2010I am using VB.NET 2005 and my problem is to sort binded DataGridView using numeric sorting (but for strings). As i understand problem is the same as in:http:[url].......or in http:[url].......My DataGridView.Datasource = DataTable. I want DataGridView to be able sorting numericaly when Column headers are clicked. This common function must be very easy, but unfortunately it is not :(. How can i get write sorting? I don't find answer in internet.Link1 is without explanable and i think it is for unbinded DataGridView and link2 is for for C+ or C#.
Examples:
Real Sorting when clicked on "Ports" header (other columns need write sorting too):
"COM1"
"COM10"[code].....

View 3 RepliesVS 2008 Call KeyUp Event From MouseUp Event For A Textbox?
Aug 16, 2010In VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp
Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp
How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?
Converting Text Containing Alpha-numeric & Special Characters To String Of Only Capital Letters And Numbers
Nov 19, 2011I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.
Get System Wide KeyUp Event?
Jul 15, 2011Currently I am able to see if a key is currently pressed via the GetAsyncKeyState function. Currently I just simply have a timer running in the background that constantly checks if a certain key is pressed in order to run a command. However my issue is if the user holds down the key it will continually run that bit of code over and over per timer tick. Is there a way or another function to detect a keyup or keypress only. This is my current code to detect keys:
Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Windows.Forms.Keys) As Integer Public ReadOnly Property CurrKey(ByVal key As Windows.Forms.Keys) As Boolean
Get Return CBool(GetAsyncKeyState(key))
End Get
End Property

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?
Keyboard Up / Down Event - Error: KeyCode Is An Integer Not Byte

View 8 RepliesPrevent Enter Key Passing Through To The Next Controls Keyup?
May 2, 2012I am working on an application using a form with textbox controls as a menu. Pressing enter while the textbox has focus invokes another form and hides the menu form. The reason for this is a requirement that the mouse must not function at all in thisapplication. Not my idea but it is my job to make it so.The problem I could use some. When the user presses enter on the textbox on the menu form the keypress event is used to invoke the selected data entry form and the menu form is hidden. When the data entry form opens the cursor is supposedto be in the first field on the form but the first controls keyup event triggers and the enter keypress from the menu form is still active so the cursor moves to the second control on the form. Having the enter key move to the next field like tab does is also a requirement.
In the keypress of the textbox on the menu form e.handled is set to True but that does not prevent the passthrough. I realize there are many ways to force this to work as I intend by putting flags and so on in the data entry form but I have many to deal with and would like to find a solution I can apply on the menu form rather then adding code to every data entry form to compensate for .NET deficiencies.

Prevent Texter / PhraseExpress From Causing Misfired KeyUp Events?
Nov 17, 2011I have a VB.NET application. When Texter or PhraseExpress is installed and enabled, the program behaves poorly. Debugging has revealed that at times I can press Enter in a field and no event will be fired (i.e. no breakpoints in the event handlers get hit), then I press it again, and they will be fired twice. (Basically these cycle if I keep pressing enter - one time nothing will happen, the next I get two events, the next keypress does nothing, the next triggers two events, etc.)
Since Enter is used in certain places to trigger searches, or to move between fields for fast data entry using the numeric keypad, this effectively breaks the program in these spots. The problem is highly repeatable - disabling Texter or PhraseExpress causes the program behaves perfectly normally. Enabling them again causes it to break. Note that in both text expansion programs, I have assigned NO events to the Enter key. In fact, with Texter (haven't done this particular test with PE yet), it happens even if NO replacements have been defined at all, simply based on whether Texter is enable or disabled.
