I have 2 buttons in my form, one to hibernate the pc, and one to put it to standby. However, when I click standby, the pc hibernates too.I want to disable and re-enable hibernation, but I need to detect whether it is enabled or not, because I don't want to enable it if the user has disabled it.
View 3 RepliesI am writing an application that puts a computer in hibernation mode (Application.SetSuspendState). I have noticed that there exists a specific option that needs to be enabled for the machine to hibernate correctly and that is found in Control Panel--> Power Options --> Hibernate Tab (if this option is not checked then the machine goes into stand by mode rather than hibernate) Is there a way to programmatically check the status of the "Enable Hibernation" check box and check/uncheck it?
View 2 RepliesIt seems I cannot use Regsvr32.exe to register it, or perhaps I am just missing something? I have checked the Register for COM interop option in the project's Build. And the assembly is set its ComVisible to true.

I'm trying to send a file via FTPS. I'm a mid-level VB programmer but I've not dealt with FTPS or SSL before.
Dim thereConnectionString As String = "ftp://" & thereHost & "/%2F/" & therePath & "/" & hereFileName
Try
Dim clsRequest As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create(thereConnectionString), System.Net.FtpWebRequest)

The GetRequestStream is throwing the exception:The remote server returned an error: 234 SSL enabled start the negotiation.
I've asked this before, but it's just not working out in real life. I need to detect which OS is running. Most of them work, but not all. I define my variable:

Surely that isn't correct? these are the actual results from running the code on a machine and reading what it says. From this information, I can't distinguish between Vista and Win2008. How do I do this? What's the difference?
I am trying to writte a windows service that is meant to detect session changes like when the user locks/unlocks the computer or loggin and logoffs.The service works fine in that it starts stops etc with no problem but when it comes to the "OnSessionChange" sub i cant understand why it fails to work.

This kind of goes along with my Shut Down & Restart thread from a few weeks ago, but one of the things I'm wondering is if it's possible to detect if the system has Hibernation enabled, or in the case of Win2k if hibernation is even possible.I already know how to hibernate the computer via the Framework:Application.SetSuspendState(PowerState.Hibernate, True, True)but in my program I would like to provide the hibernate option only if the OS A) is new enough to be able to and B) has it enabled in the user's Power Options in the control panel. I can't seem to find anything via Google and MSDN that leads me in the right direction.

I have a very long running syncronization task that cannot be interrupted by the screen saver or aggressive power saving modes. I want to make a single api call to stop power save mode and then restore it once the task is done.The following code is peaced together from various other posts but it has no effect on XP's power management settings.[code]
View 3 RepliesMy app is running in the tray and I want it to give a reminder to the user its there when they resume from a hibernation, sleep, or from being locked. I know how to handle the popup, but I cant find out anywhere how to detect that 'wake' status from those power saving modes.
View 2 RepliesI have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.
View 7 RepliesAs i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
I need to find an easy way to know if the local machine's 'automatically adjust clock for Daylight Saving Time' option is enabled.

My form height is a 100
If Me.Height = "100" Then
Me.Height = Me.Height + 1
End If
If Me.Height = "500" Then
Me.Height = Me.Height - 1
End If
Now i want it to stop when it hits 500, and then scroll back...
Ive also tried this...it stop at 500, but doesnt scroll back:
If Me.Height >= "100" Then
Me.Height = Me.Height + 1
End If
If Me.Height = "500" Then
Me.Height = Me.Height - 1

View 3 RepliesI'm trying to do MVP where I have a view specific model that the presenter manipulates and the view binds to. There is no other connection between the presenter and view (the view fires off commands to the domain model via a gateway type pattern).
As you can guess, this makes the ability to bind to any property of any object really important.
I'm having trouble finding the correct way to bind to the Enabled property of a ToolStripMenuItem. Most controls have a .DataBindings property, but this one seems to lack it. I haven't found much info online about how to do this. Is it even possible?
I have a situation with several TextBox controls on a WinForm. "Rules" are processed on the Leave event of one TextBox (TextBox1) which can disable or enable the very next textbox in the tab sequence. It appears that if the "rule" disables the next textbox, focus remains on the prior textbox. In this case, the focus is in the wrong place AND, if user clicks "{TAB}" again, no events fire for TextBox1. I am looking for a solution that does NOT require hard-coded knowledge of the tab sequence to make tab navigation (and events) work properly. See small code sample below that demonstrates the problem:
private void textBox1_Leave(object sender, EventArgs e)
{
if (textBox1.Text == "bob") // simulating a "rule"
[code].....
The problem was first identified because of rules triggered in a class entity that was "bound" to the form controls, but data binding does not seem important to the symptoms.Is this a quirk/limitation of the WinForm event model?Rhino907
I'm trying to create a routine in my asp.net's main page that will see if the current user is a member of a Windows domain group. The site is hosted in IIS and is visible through our intranet.

UserName = System.Environment.UserName
If Roles.IsUserInRole(UserName, "MyDomainMyGroup") Then
[Code]....
Problem is, now I'm getting the configuration error 'Default Role Provider could not be found'.
How can I get around this? I just need to see if the current user exists in a specific domain group.
Put a Datagridview on a form, fill it with data. dgv1.enabled = True and dgv1.enabled = False are almost the same look to the eye unlike other controls (textbox,combo, listview, etc ...) where there back color changed to light grey and you can distinguish if that control is enabled or disabled but not for Datagridview.
View 2 RepliesIs there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?

View 1 RepliesI have a Nag Screen that I am creating, and I am wanting to create a delay before the OK button is enabled allowing the user to proceed.
Is it better to use a Timer event or would a 'For I = 1 to 20000"

All this timer would do is Enable the OK button, thats all.
I'm trying to enable tabs funtionality in the WebBrowser control. I have a TabControl hosting WebBrowser controls in each tab. And a multiline enables Textbox to enter the sites. It looks something like this[code]...
It adds the WebBrowser control to the TabControl at the SelectedTab position. Since the default selected tab is the first, it only adds it to the first tab therefore executing only that browser.
I want to know how I can select the next tab from the loop as the SelectedTab so that when the loop runs again and again, it would keep adding WeBrowser controls to each tab.
