I am trying to create an application that logs off a computer. I want it to check for mouse movement. If the mouse hasn't been moved in a certain amount of time then log off. I created an application for a form that if the mouse isn't moved in the form in 5 seconds the application closes. The reason I am trying to create this is because I work for the board of education and we have a problem with the teachers not logging off. The students get on there computers and mess stuff up. So my questions are:
1.) Is there a way to record mouse movements in windows instead of just the form? tutorials/info?
2.) Is there a way to execute a command like you would in a command prompt? For example if you type in shutdown -r it will restart the computer. tutorials/info?
3.) I do not want an interface for this just an icon in the task bar and for it to start on bootup. tutorials/info? When it reaches the time I want it to pop up with a form and say logging off in however many seconds and then logoff.
I have a bound windows form with a bindingnavigator control. I want to add save and new record commands to a menustrip. How do I code the menustrip selections?
I am trying to create a update application for Windows CE.
It will go out on the net to my site and see if there is any new updates but I am having a problem doing that.
Firstly it is working fine if I create it using a 'Windows Application' but as soon as I Copy + Paste the code to my 'Windows CE' app (smart device, windows CE) it comes up with an error.
I am using .net framework 2.0.0 and vb.net 2008
Here is the code which I am using:
Code: Function DownloadFile(ByVal sURL As String, ByVal pProgress As ProgressBar, ByVal Filename As String, ByVal Prefix As String, ByVal Rename As Boolean) As Boolean Dim wRemote As System.Net.HttpWebRequest
I know there are many posts about updating an application with UAC turned on. We have a huge application and our own update program for updating that. We don't want to use the UserAppData area to install our exes. We do mostly custom programming so updates are a part of like for us. My question is: If we get our update program digitally signed can the standard user with UAC turned on accept those changes without administrator privileges and can that be done to a VB6 executable.
I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.
What are the best practices to develop a software in such a way that I can release updates, I mean I can release an update which replace the existing executable but in case I have added some new references (dlls) to the project this won't work ? Is there any way I can do it without running an MSI?
I am having an application in both windows and web domains.The web part of it have only limited features compared to it's windows counterpart.But for my case (an appointment fixing module which is done using both domains),I want both databases to update with the other database.
Is it possibel to use update panels and update progress controls in windows application or is that reserved for web apps only. I am looking at applying some progress controls (like a spinning wheeel etc) when loading a crystal report that take about 30+ seconds.
I have seen this happen before but am not sure how I resolved it in the past. On runtime the controls of my form change from the windows 7/vista format to an older version format as shown in the attached image.
How to display the controls in the format on the left (new windows format)
During the first form_load a thread is created from a function of second class(hb) which constantly works and changes the status of parameters i.e enabling or disabling some buttons on GUI of form1 But it is not happening.Problem is the [code]...

I have two, soon to be many spreadsheet files. There are cell references between the files which need to be updated. I would write this in a excel macro but these spreadsheets are design tables for Solidworks, a CAD system and it does not allow macro enabled workbooks. So what I would like to do is push a button and open all of the spreadsheets, accept the update workbook prompt then save and close the files.
I've seen a similar command developed by someone using the Soildworks API but updating design tables in solidworks takes ALOT of time to run compared to just opening and closing spreadsheets.I am using Visual Studio 2010 Beta 2 along with Excel 2010 Beta 2 (I like to have the new things)
I want to take the values from textboxes on a windows form and then update the values in the sql server database...I want to update only those fields for which a value has been entered by the user and leave the database fields as it is (no change or updation) for which the textboxes are left empty by the user.....I opted for sql command and then i couldn't find out How can I generate the query dynamically for such a situation??? Like I intialize the string by str= " Update Bookings set " and then how i can alter it by considering the textbox values that have been changed....I couldn't find the way...I need shortest and optimized code for this situation....
I'd like to write a simple Windows form that will make it easy to record a voice message before uploading it to a remote web server and sending the URL to the recipient(s):
[URL]
Currently, the user has to use Sound Record to record the message, use an FTP client to upload it to a web server, and finally, use an e-mail client to send the URL. I'd like to combine those three features into one.
I have a VB.Net project that I am running from a local server and I need to use the credentials the user is currently logged in with to upload a file to a folder I create on a SharePoint site on the same domain. I can get it to upload if I specify the credentials but it will not work with system.net.credentialcache.defaultcredentials. It just gives me 3 empty strings and I get a 401 unauthorized error. I have seen a few threads that say you cannot use it with Windows Forms Applications. Is this true? Here is my code:
I Have one Windows Application in which i have one MDI Form (Say App1). And I too have another Windows Application in which I have a Child Form (Say App2). So now i want to Call App2 from App1 .. And want to Display App2 form As MDIChild in App1 MDI Form . I am Able to open the Form of App2 , But how to set It As App1' Child .
I have a console application code below. I am trying to convert this to a windows based form application but I don't know where to start. This code asks you to input a website and then it gives you the IP address for that particular website the user enters. All the code works fine but I want this in a windows form application.
using System; using System.Net; using System.Net.Sockets; class GTest
I am creating a program that interacts with another program and I would like to "inject" my program into this program as an MDI Child window. Is this even possible, and if so can it be done in VB.NET? What kind of pitfalls are associated with doing this?
I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I want to take the values from textboxes on a windows form and then update the values in the sql server database...I want to update only those fields for which a value has been entered by the user and leave the fields for which the textboxes are left empty by the user.....How can I generate the query dynamically for such a situation???
Edit:
I haven't yet coded for the update option...Here is my insertion code and i wanted to implement the update feature the same way just couldn't figure out how i can generate the query dynamically....It's a Booking System application
With the following code i am able to update record in the first row. Can some tell me what i have to replace in this code to update a record for a selected row. I have a field "Sr_No" with primary key.[code]...
I have a form with a list that shows information from a database. I want the list the update in run time (or almost real time) every time something changes in the database. These are the three ways I can think of to accomplish this:Set up a timer on the client to check every few seconds: I know how to do this now, but it would involve making and closing a new connection to the database hundreds of times an hour, regardless of whether there was any change Build something sort of like a TCP/IP chat server, and every time a program updates the database it would also send a message to the TCP/IP server, which in turn would send a message to the client's form: I have no idea how to do this right now Create a web service that returns the date and time of when the last time the table was changed, and the client would compare that time to the last time the client updated: I could figure out how to build a web service, but I don't how to do this without making a connection to the database anyway The second option doesn't seem like it would be very reliable, and the first seems like it would consume more resources than necessary. Is there some way to tell the client every time there is a change in the database without making a connection every few seconds, or is it not that big of a deal to make that many connections to a database?
