My main form has a timer that monitors idle time in my app: no mouse movements and no clicks.If the idle time reached 3 seconds, in *this example below*, then I want to show frmRestart, which will call the UnloadAllFormsExcept(Me) function from frmMain.When three idle seconds are reached, frmRepeat starts to show on the screen but never does!! I just see the border of the form and nothing else. My mouse goes into "thinking" mode forever.[code]
way to reset a timer if there is form activity so it will not expire until the mouse has been at rest for 2 minutes.
This timer runs for 120000 milliseconds usually, and sometimes it lapses (and logs you out) when you are in the middle of editing. Sometimes 2 minutes is not enough time to do all the edits. So I wish to reset the remaining interval as long as there is mouse activity. But I am not sure the best method to do this?
I have found the mousemove event but to me this seems like it's going to fire way too often and tax the resources if I preform operations here, maybe not? Is there a better way to get this functionality?
I want this functionality so that if someone starts editing on the UI and walks off/gets distracted it will lock the grids back so that some other user can't come dork things up.
Is there a command in vb that can be used to pause a routine to give time for the form to show before the routine starts as my routine is running and completing before my form shows up?
I'm making an application in which I'm implementing auto-monitor turn off when system is idle, i.e. when user is not interacting with the system. [URL]it does provides the componenent to know when system is idle. But when I include:
Public WM_SYSCOMMAND As Integer = &H112 Public SC_MONITORPOWER As Integer = &Hf170 <DllImport("user32.dll")> _
[code]....
It shows this error: Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on.
I would like to get the idle time of my winforms application (not the system). This will enable me to update the database to show which users are online/offline amongst other things.
I need to get the sytem idle time.It must be developed in vc++ and the code should not use hooks is there any possible way of getting SystemIdleTime from taskmanager
Windows resets the IDLE time every time the user touches the keyboard or the mouse. My application needs to reset the IDLE time at specific moments, but how to do this programmatically.
The following does NOT reset the IDLE time using VB, C# or QT4. - Programmatic mouse movement / click. - Programmatic keystroke. Somehow Windows knows these actions are simulated. How can I reset the IDLE time?
i have a combobox that has 3 cases. case "0" opens a dialog saying, "Not a valid choice"but case "1" and case"2" open up there own separate forms. (FormMain and Form3)How do i make it so if Form3 is open FormMain Can not be opened, And a messagebox appear saying so. I do not just want the ".hide" function. I already have that set.I have tried a few differant things, none of which worked. And i tried them in the formload and in the combobox selected index
My Project having form-1 & form-2. Project starts with Form-1.From the form-1, button1 - click() I want to close the form1 and from2.showform2.show showing form2, but the form-1 is also still opened. How to close form-1?I tried from Form-1 as me.close(). then Form-2 is not showing.So how to close form-1 at the time of form2.show?
I have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _ Public Property DataEntryRole() As UserRole.PossibleRoles Get Return mDataEntryRole End Get
[Code]...
When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.
The first column in my Data Grid is actually not my first column. It has an arrow pointed to the first row and then the last row has an asterisk by it. Is there anyway to make this column not show every time my form loads?
Adding How would you detect if the user is using the computer? I want a program to detect if the user is using the computer (i.e. mouse and keyboard movements), and if the user doesn't type or move the mouse for a specific amount of time, it executes a command. Normally I would do this with the Application.Idle, but I want it to be detected throughout the system. Any starters?
New to VB.NET Programming. Im trying to set the dates pickable on a Date Time Picker to the current day and onwards, i do not want someone to be able to chose DateToBeShipped to yesterday for example.
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
Basically i'm trying making a task manager program for myself. I want to know how I can display a message box and or play a sound when system time = time displayed in listview. I have used a dropdown box for the user to select which option they would like to select - sound or message box to popup. The data for the task will be stored in a listview box. I want it so that when the date and the time is = to the date and time set for the reminder the action will follow.Here is my code so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim notext As String = "" If TextBox1.Text = notext Then[code]....
How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing
I'm trying to create a way for the User of my application to Log Off, Shutdown, or Restart the PC.
The idea is that User can more quickly access these options from my application and if they choose, force these actions instead of waiting for the OS to respond.
Here's how I'm trying to do it:
CODE:
Log Off works just fine. It's shutdown and restart that doesn't work. From the research that I've done, the Consts seem fine and the function obviously works correctly because Log Off works. I am running the application as an administrator, so that should affect it.
I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
I have to create this program for school to restart a bootcamped mac back onto mac from windows with an application made in visual basic.So I need my computer to restart which I have successfully completed. Now I just want to find out how to get the application to make my computer restart on the Mac Partition ( E: ).
Below is my timer code, click the buttons it start and stops.
What I want to do is retreive a elapsed time from a db say 01:40:00
and make the timer start from that value as opposed to starting over again if the application crahes. how to set the saved time and start from that point.
Public Class Form1 Private stopwatch As New Stopwatch Private Sub counter_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles counter.Tick
I use this to delete cookies System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2") works fine I checked the folder myself it deletes all .txt files.
But here Is the problem lets say I log into hotmail, Clicked the button to Clear my cookies. And navigate to log in page again, It will navigate me straight to inbox just as if I have cookies but the folder doesn't have .txt cookies file. just (index.dat). Is this means we must restart the program to this to take effect? (Works if you restart it) If so, how can I turn off webbrowser1 for a sec and turn it back? or something like that just to make sure it takes effect without me reopening the program.
