View 3 Replies.net - C# DataGridView Capturing Deleted Row?
Jun 16, 2010I am using a DataGridView, which is bound to a dataset. There is a bindingNavigator as well.
when a user deletes a row by clicking "bindingNavigatorDeleteItem" button, I am trying to get the row being deleted.
private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
{
int crow = gridEventType.CurrentCell.RowIndex;
but it returns the newly selected row AFTER deletion of a selected row.
so, If I have two rows
0
1
2
and I delete 2
crow is 1, not 2.
Am I missing something here?
2. How do I know whether certain rows are modified in datagridview?
.net - Capturing Error Events?
Feb 9, 2012I was creating some complex applications in Visual Basic .NET 2008 and since they are in the testing phase right now, people manage to find an error or two every so often that causes the program to crash. The problem is that there is a tracking piece to it that logs who is currently using the programs. When a user logs in, it logs that they are currently logged in, and if the form close event is fired, the log is deleted to show that they have closed it.
Now my problem comes whenever the form crashes from an error since it won't trigger the close event and therefore makes the log become inaccurate. My question is if it is possible to capture any error that the form would have in the form of an event?

Capturing And Using Keypress Events
Apr 30, 2010I am trying to modifying the "Math Quiz" tutorial to be more user friendly.
The initial tutorial does not consider the users efforts to answer the math problems as quickly as possible.
The problem is that you must use the mouse or tab key rather than the "enter" key to move to the next control after answering. I believe using the "Enter key to be much more intuitive.
Therefore, I wish to modify the program to either:
1. Check the KeyPress event of the NumberUpDown controls to watch for the "Enter" key to be pressed, and if it is, check to ensure that the current NumberUpDown control is not empty (= Nothing) and if both are True, to then TAB to the next control in the TAB order; OR
2. Uses the PreviewKeyDown event to transpose the "Enter" into a "Tab" automatically so the application will then TAB to the next control in the TAB order.
With all of the new changes to VB 2010 from the last version I actually used professionally (VB6), things are REALLY different, so I no longer know how to accomplish this same task in the new manner. especially if it contains working CODE, because I have always learned better the first time from an example. here is my version of the tutorial Code:
'--- Create a Random object to generate random numbers.
Private objRandomValue As New Random
'--- The Integers will store the numbers for the
' addition problem.

Still Image Capturing Using A WEBCAM
May 28, 2007I would really like to get some VB.net program code for still image capturing using a Webcam.I've searched the web for quite a while now but did not get any codes. Currently i have a code for capturing video. In that code an image can be captured, but only with 640 X 480 resolution (Maximum Video resolution for my web camera). The WM_CAP_DLG_VIDEOFORMAT dialog box only allows the resolution to be set up to 640 X 480.

Add The Mouse When Capturing The Screen Or Monitor?
Jul 18, 2012I'm just wondering if it's possible to add the mouse when capturing the screen or monitor in vb.net?
because I'm doing a project that would record the screen and I'm actually successfull doing that by capturing the screen and include it in a timer, but my only problem is the mouse or the cursor isn't showing.
below is my sample code.

View 5 RepliesCapturing (and Canceling) A Minimize Event In .NET?
Nov 21, 2010I'd like to start by saying that simply though searching, DreamInCode has taught me alot about VB.NET. In fact, I would imagine without DIC as a resource, I probably wouldn't have been able to move forward and learn most of what I know now, just because I got stuck on some things here and there.Anyway, I searched around for information regarding how to "capture" a minimize event in VB.NET. I am working on the GUI for an application that I would like to have minimize to the system tray. Currently, instead of accomplishing this with the minimize function, I do it on the FormClosing event like this:
Private Sub MainFrm_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
'Cancel the attempt.
[code]....
That code works, and upon making the form visible again with Me.Visible = True the form is restored to its original position. However, prior to the form being hidden, the window manager draws a minimize and restore effect before eventually hiding it. Any change to the WindowState _after_ hiding the form does not appear to have any effect, so when the form is unhidden it is still minimized.is there a way to capture Minimize events, and when captured, is it possible to cancel them in a manner similar to what I did with the FormClosing event?

Capturing Screenshots As A Windows Service?
Jul 29, 2009Basically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically.
The timer is working fine and I have tested this.
The purpose of the service is to monitor the desktop over night when the user is logged off, by capturing screenshots and saving them to file. This is so admin can be alarmed about security breaches etc.
The problem is is that I have not found a way to capture desktop screenshots as a windows service (or otherwise) while the windows logon screen is active (i.e: when the user locks the computer). I have used google extensively but to no avail
