Detecting Checkbox State In DataGridView?
Feb 3, 2011I 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

Webbrowser Not Detecting Flash Installation
Mar 4, 2009I'm a novice in Visual Basic and I'm currently experimenting with development of a small application that includes webbrowser control. When I tested the browser (actually tested a few of them, not developed by myself) accessing websites using flash content, it always returns message "Flash not installed" and prompts me toh have it installed. I remember IE6 used to have problems of this kind.IE7, FF and other browsers work just fine and detect flash plugin straight away.This is probably a known issue, but I just couldn't find anything on it in these forums.

View 2 RepliesDetecting JavaScript HTML Page Modification In WebBrowser Control
Jul 23, 2010My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]

I don't just want to navigate to the same URL as in the original WebBrowser object, rather I want to repeat the HttpWebRequest.

VS 2010 Detecting Laptop Lid Close
Nov 16, 2011I'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 RepliesVS 2010 Detecting Lid Close Change
Dec 7, 2011I'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 RepliesWebBrowser Control Is In A Wait State : How To Kill The Wait
May 27, 2009While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

VS 2010 - Detecting Mouse / Keypress Input
Dec 5, 2011I 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?

View 3 RepliesReading EXCEL In 2010 Detecting Blank Cells
May 16, 2012My 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?
