View 6 RepliesI have a DGV with a CB column in VS2008. I would like an event when a DGVCB selection is made (without leaving the cell). It will probably have to be a DGV cell or row event but I can't find one that fires as soon as a DGVCB selection is made.

I was thinking get the row index and then the cell index and using that to get the specific cell I need somehow but I do not know how to get the specific cell, so would this be easiest if so what command would I use to get the information from the cell, if not how would a better way to do this be?
I cannot find the way to get the row index if one exists so I am guessing it does not exist with this method so how would I go about getting the information from a specific column of a selected row?

Select Case e.KeyCode[code]....
This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown If e.Modifiers = Keys.Control AndAlso e.KeyCode = Keys.A Then

And whenever I click control-b (on keyboard) it inserts the bold tag twice.why does it do that? i use to have that code in a button, and the keyboard event would lead to button1.performclick but now when putting the button code in the keyboard it adds the tags twice
Im trying to send keys to cod4, Jump (space) works perfectly after i added the keyup after keydown, Before i added Keyup for W (move forward) it would jsut spam and keep running forward, but after i added keyup it doesnt move forward at all, not even a little bit
note: it does send W and space to regular windows,
ElseIf command.Contains("keyboard=space") Then
Call keybd_event(System.Windows.Forms.Keys.Space, 0, 0, 0)
Call keybd_event(System.Windows.Forms.Keys.Space, 0, KEYEVENTF_KEYUP, 0)

Private Declare Sub Keyboard_Event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long) [Code] I know the KeyCode when i call this function. Example 13 is the keycode for "Enter". But it says that theres an error on syntax cause KeyCode is an integer not Byte. What kind of variable does it need there? I mean does it need the keycode (which is a number) or a character e.g. "a"? [Code]
View 2 RepliesI have the following code which I use in another Form and it works perfectly. I copied the same code to another form, changed the controls, keys combinations, etc., but the keyboard shortcuts do nothing at runtime. None of the key combinations work, it throws no Exceptions,I put a MessageBox in the F1 KeyDown conditional, but it doesn't show. That tells me that it's not Handling the KeyDown Event.[code]

So question is how to describe in Visual Basic [Escape_key_was_pressed] function? When user don't hit Escape key, then program must NOT STOP for asking user keypress[Escape_key_press], it must go on with clicking on desktop to the end of program. SteelAce
I've adapted the code from this link to use the WinXP on-screen keyboard (osk) for a touch-screen application written in VB.NET v3.5. The osk fills the bottom half of screen etc. and behaves fine except for one little quirk. If the user clicks or taps anywhere on the 'background' area behind/between the virtual keys (within the main osk window), the color of the area changes to that of the keys when any further key subsequently gets focus. The outline of all keys is then lost because they are visually merged into the osk window background. The osk must then be terminated and re-launched to remove the confusing appearance.
This behaviour only occurs when the osk window is set to the child style (i.e. when the menu is hidden), using the SetWindowLong P/Invoke function - e.g.
SetWindowLong(OskProcess.MainWindowHandle, GWL_STYLE, WS_CHILD)
It's as if the entire area behind the keys is being treated as another key when tapped/clicked, whereupon its color is 'restored' after losing focus.Is there any way to intercept and somehow override the focus event of this osk background area?

View 1 RepliesI have a DataGridView with two columns. One is DataGridViewComboBoxColumn and other is DataGridViewButtonColumn. To capture the button click from the DataGridViewButtonColumn, i have written the CellClick event and it is working fine. However, this is not making my selection from the DataGridViewComboBoxColumn 'smooth'. What i mean is that i have to click on the combo-box twice for it to show the drop-down list. I have noticed that at every click, CellClick is fired. But only after the second click the drop-down pops out. What is the work-around for this?

I have two forms, forms a and b. Each form has a combo box. The user selects an item from form A's combo box and saves their selection to a database by pressing a button. How can I display their combo box selection from form A in form B's combo box on form B's form_load event?
View 1 RepliesI have a ComboBox that is databound to an ObservableCollection of strings. The ComboBox is also editable, so you can either enter in your own value or select one from the list. The issue I'm running into is the index of SelectedItem seems to be the index of the last item you selected when you've entered in your own value in the ComboBox, though it's -1 when you have IsTextSearchEnabled set to true. The problem is, if someone entered their own value and then decide to instead select the item on the ComboBox that had been selected before, the index doesn't change so the SelectionChange event doesn't fire. How could I get an event to fire in this situation?

Currently, when I double click on my current list, even if there isnt an item at the current mouses location, it calls the event and uses the last highlighted item. I know it is possible to fix this by using a selected index change event, but I require the list items to be double clicked

View 1 RepliesI was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?
