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 1 RepliesMy 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]

How can I detect the click event of the close (X) button at the top right corner of the control box of a form/window? Please note, I don't want to know about CloseReason, FormClosing, FormClosed or stuffs like these, unless they are inevitable. I exactly want to detect if the user clicked the X button of the form.

View 1 RepliesFirstly I apologize as my question may seems repeated to you. But I am sure the details will not. I am writing a VBScript in VB.Net to automate some operation in SAP. The script is recorded from SAP. All I need to do is to put this script under a button click event on vb.net. I have done this far. But get stuck at one point. While doing the execution of the script, SAP displays a Message Box with two button labeled "Redetermine" & "Cancel" and I have to Click on "Redetermine" button to make the script run further.
The number of appearance of this message box is not fixed. Some times it appears twice and some times more than twice. My question is "How can I detect the Message Box from my VB.Net application and automatically click on the "Redetermine" button if the message box appears"?
detecting the string between 2 characters, EG " is the starting character anything the user types is the string" is the ending character
like this:
" <user text> "

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?

My 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?

I 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.
