I was investigating on Google wether there was any sort of code that would return the current state of a laptop's 'lid'. I need to be able to find the state of the lid and be able to execute code before the defined event in Windows Power Management is executed.I have come across ExCreateCallback and stuff on MSDN however I wouldn't have the faintest on how to implement it into VB.
View 4 RepliesIs there a way to detect when a laptop is docked or undocked? I know how to get the "dock" status of a laptop using GetCurrentHwProfile. So is there some type of event raised when a laptop gets docked/undocked that we can catch? I did do something similar in the past for the detection of USB devices using a ManagementEventWatcher ...
View 2 RepliesI'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.

I'm trying to track down a problem on our test environment. Previously it was set to use InProc Session State Type, but I've added in the SQLServer type for one specific Web App. I did this because we use the SQLServer type in our production environment and I want our test env to match as closely as possible.
However, after changing it to SQLServer I do not get any errors when trying to store unserializable data in session like I would expect. It works just fine, even though I would think it shouldn't. I'm a relative newbie when it comes to configuring this, but from the various tutorials I googled, I thought I covered all the bases.I was wondering if there's any code snippets to verify which session state type an application is actively using.
In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another
View 5 RepliesI have a code snippet that I want to run when the app is closing. So, I used FormCLosing event. But now i wanna place a confirmation message for exiting. Like, if the user clicks the Exit(X) button, there'll be a prompt, if he clicks NO, then the app will not close and revert to previous state. Now I find that hard to achieve using FormClosing event. because it'll get executed no matter what button the user clicks.

View 7 RepliesWhen you you right click on a textbox the context menu is automatically open.
I have put a textbox inside a relatively complex user defined user control.
The annoing thing is that when I try to open the context menu with a rightclick the context menu is open but it shuts down soon after.
I tried to see if the mousedown or mouseUp of my (preview and not) usercontrol could interfere with this but i did not find anything.
Is there any trick that I can use to see what forces my context menu to close soon after is open?
Is there something in Vb2008 that allows me to see the steps widthout using breackpoints

View 4 RepliesUsing VS 2005 and SQL Express 2005. This WinForm application runs fine on 5 out of 6 stand alone computers that is it installed on. The 6th computer is slightly older running XP sp2.As I understand it, using DbDataAdapter will perform the open, close and dispose functions for you. Therefore, Pooling should not be an issue. I am thinking that the default 15 second time out setting may be the cause?? There is some MultiThreading that will also use DbDataAdapters in the same manner but only 3-4 would be firing at the same time.The connection string is Data Source=(local)DataBase;Initial Catalog=Code;Integrated Security=True The command which throws the exception is If CodeDataAdapter.Fill(CodeDataSet.CodeTable) > 0 Then...So I am thinking that adding Connect Timeout = 60 to the connection string even though the 15 second default seems like a lifetime. Could this 15 seconds be eaten up if some other process or application takes over?
View 3 RepliesObjective : Time how long a user has been on the internet. I have never delved this deep into Visual Studio. I am suing Visual Basic 2010 Express. Please move it if you need to.
I want to have a program - that will detect running processes. If Internet Explorere EXE or Chrome or FireFox exe or any other browser is installed - as soon as that process starts the timer will appear.
When those processes are closed by the user the timer stops counting. This is possible but i dont know how. But i only want it to time just one internet process because timing them all when they are openend up at different times could cause bugs. Unless on the time form you have 1 timer for IE, 1 for FFox, 1 for Chrome 1 for Opera..

View 8 RepliesI have some code that loops in the background of a form and triggers action if the form is active (this is in a mdi forms application). I use the following to check this:
vb.net
Dim frmActive As Form
frmActive = Me.MdiParent.ActiveMdiChild
If frmActive.Name = Me.Name Then
'Do work
End if
The problem comes when that form starts another form running in dialog mode i.e. form.showdialog. I need the above code not to run while this is the case, but it still returns true when the dialog form is active and the other form is in the background.
Is there any way to detect whether a dialog is open in an mdi environment?
