I am trying to detect when the user selects a checkbox on the new line of a datagridview
I am using the following code but it doesn't detect the new line has been selected. When running debug IsNewRow shows as FALSE
Private Sub DataGridView1_CellContentClick(sender As System.Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

I try to detect when the mouse is over a curve in zedgraph, I am capable of doing it if the mouse is over a point of the curve, but the problem is when the curve has no points in that region,let me show you an example:
Curve is defined by 2 points: [X=0;Y=10] -- [X=1000;Y=10]
If mouse is at point [X=500;Y=10] it is over the curve, but not over any point so i cannot detect it.Is there any event which gets fired when mouse is over line but not necessarily over a point?
I have searched for this, and not been able to find any examples where someone has done this. I'm trying to add a new line into the cell of a DataGridView so the text appears on 2 lines (of the same cell). Here's some code to explain what i'm doing:
Dim DS As New DataSet("aa")
Dim tbl As DataTable = DS.Tables.Add("bb")
Dim xRow2 As DataRow = tbl.NewRow()

I am building an application where on a form is a datagridview and textboxes. The dgv and tb are bound to the same table. I am using the dgv to have an overview of the records and the tb I use for editing. Selecting a record programmatically in the dgv is no problem, but the textboxes have to be filled with the same record. Here I have added my code to this far.
If OuderID <> 0 Then
'select the row
For i As Integer = 0 To dgvOuders.RowCount - 1
If dgvOuders.Rows(i).Cells(0).Value = OuderID Then
[CODE]...
I am stuck right now. I want to add (on the dotted line) an performclick action, but a dgv doesn't have a performclick action.
I have a DataGridView control in a .Net application that contains a checkbox column. I would like for the user to be able to edit the checkboxes. The issue that I am running into is that I cannot detect the state of the checkbox after the user checks it.
If the checkbox was originally checked, then it will return checked as soon as the DataGridViewCheckBoxCell gets focus. But, if I click on the checkbox again and unchecks it, then it still returns checked. From that point on, it will always return checked regardless of the actual state of the checkbox until it looses focus and gains it again.
Likewise, if the checkbox was originally unchecked, then when it gets focus it will return unchecked in the click event regardless of what the state of the checkbox actually is.
Here is my code.
Private Sub grdTemplates_CellContentClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles grdTemplates.CellContentClick

I have implemented tab control on an existing form by using form designer and copying button from an existing vb application. my goal is to run a piece of code when a button on a tab page is sellected. How do I go about implementing this? I can detect in the code which tab page was selected but not that the button on the page is sellected.

View 6 RepliesI have a program which when a button is clicked on a form sends the form to the back, so that Notepad can open on top, then it opens up notepad

Now what I want to do is to detect when the notepad has been closed then I can bring the form back to the front and I just do not know which commands to use for this to detect a program outside of VS 2010.
I've been searching this for quite a while now, but I've come up with very little so far. I need to figure out how to determine when a laptop lid has been closed so an execute an action when this occurs. But the power settings will be setup to where the laptop does not go into sleep or hibernate mode.
View 5 RepliesI've been attempting to determine if a notebook's lid has been closed when the power setting is set to "Do Nothing."I was able to get this to work by trapping the WM_POWERBROADCAST message, but it would only work when the computer when to sleep. I've tested this on many different notebooks and the results vary. Even when changing the power settings correctly, the results were fairly inconsistent.So I posted this question in General Developer and penegate offered a possible solution.[code] I'm thinking that maybe the message I'm trapping isn't correct, but I'm not 100% sure. When I Google that message, nothing comes up. Two links appear. The one on VBF and some German site. Nothing's on MSDN.

View 6 RepliesI am creating an application that creates scripts to move a mouse and to click where a user wishes to via pre-programmed code and to also press keys where required. I have the code to move a mouse and to manually click anywhere. What I am after is to detect when a mouse button is pressed and dragged and when keys are pressed.
I see that there is the following
MouseButtons.ToString
To detect when a mouse button is pressed, and have it looping in a timer. Is there a better way to do this? I would rather not use a timer. And is there a similar routine to detect which keys are pressed?
I'm trying to detect the Printscreen keypress with the use of a timer. I can't useform1_keyup/down as the focus isn't always on the form.
View 4 RepliesMy Visual Basic .Net 2010 application reads data from an EXCEL spreadsheet which will be generated by my "customers". The responses to Alkis last year (23 July 2011) has been a big help and got me over a hump in my application. Now I am down to the last issue - how do I detect a blank cell? Valid data is numeric, starts at a fixed cell (A5 to be specific), and will be continuous until it ends with blank cells. While blank cells appear to print a "zero", when I try to use zero as an end criteria I get a 'System.InvalidCastException'. When I put in a specific end value (-1) in the last cell all works fine but that, of course, is an invitation to a user error.What is the difference between "Value" and "Value2" and where might I find documentation that explains the difference?

View 8 RepliesI need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.
