I just want to inquire if it's possible to create a program that can lock not only the application but the whole system(PC)? What I want is that, if my application wasn't used within a specified time frame, it will automatically olock the whole computer and it can only be unlocked by a password.
View 8 RepliesI have a weired problem. I developed a multithreaded WinForm application using VB.Net, and SQL Server 2008. The application works perfectly fine if I am using Visual Studio IDE to run the same. But, if I run the exe file created by VS the application hangs in case I lock my system and again relogin. The memory usage is same as it was before locking the system. CPU usage is also 0% or by max 2%. All threads are also exited after finishing there designated tasks.The application also uses threading but all threads are exited after there designated tasks. I confirmed this using various tools.[code]
View 5 RepliesI am trying to create an icon in the system tray as status for num-lock, caps-lock, and scroll-lock, because my keyboard that came with my computer does not have status lights on the keyboard, and only on the system tray.
The program however that came with it, does not like to work when I have some games open and stuff, it works usually in IE, and most other programs, but some programs just seem to interfere with it.
I have made a new program on a 1 mili-second timer for the 3 and it seems to work just fine in the application, I was wondering now if I could move that over to the system tray and make it look like the one that came with computer, it has 3 different icons, and the icon changes for on/off and has a tooltip status change on mouse-over showing status of on/off.

View 7 Repliesi want to implement in a program. I'm not asking for code just some advice and maybe a link or 3 to useful pages on the internet.I want to create a plugin system for an application that i want to make. The idea for the plugin system is based on the following...
1-Some graphics editing programs have what i think is called a filter/effects chain. its where you make a list of filters and settings that the program runs to edit the image.
2-In yahoo pipes you take small parts and use them to complete tasks for you mashup (like pulling all the images returned in a search and displaying them).
The system i want advice on is basically a plugin chain system modeled after these 2 idea's where the user selects plugin's and forms a chain out of them.for instance if i wanted to display a picture then i would form a chain of plugins like this
legend:[(inputs)what it does(outputs)]
[show open dialog plugin(output filepath)] -> [(filepath input)open picture plugin(output bitmap object)]->[(input bitmap object)Display a picture plugin(make a form for display)]
The code for the task's will of course be in the plugin's.The problem is i have never done any plugin system before. the hardest part i need help with is getting the plugin's loaded and sending the output's to each other. Also another problem i think is that the plugin's could be for anything (parsing text, displaying a picture, opening a url, downloading a file, etc, etc)Again I'm not asking for code just advice and some useful links to information.

View 4 RepliesI have a school project due in January to make a program in vb. The problem i'm encountering is making the actual login system. I only started using vb last year and that was purely console applications. So I am completely new to forms and I don't know ANYTHING...
The login system should be complex to an extent that it shouldn't just be a simple if statement. I have to make it so that users can create an account and that username and login will save somewhere where no one can access but vb can read from and to that directory.[code]...
I'm wanting to develop what I perceive to be a pretty simple application. I want something that runs in the system tray that tests for the presence of a particular file on a network drive. If the file does not exist, the icon in the system tray is a green circle (like a traffic light).If the file DOES exist, then the system tray icon is a yellow circle (caution), until the user clicks it (the yellow system tray icon), and a record is written to another file, then the system tray icon changes to a red (stop) circle until that first file we tested for is gone.I'd also like to create "balloon messages" to go with the changes in the system tray icon.

View 2 RepliesCan anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.

View 3 RepliesI need to create a notification system for my application that will alert the user once new items have been sent to their queue, which is made of up database entries. The latter part of this question may need to be asked in the database forum, but I guess we'll figure that out First, since I haven't created anything like this before, I need some direction on what the best possible solution would be.The notification system should always be running and work independently of the main app. With this requirement, I thought a Windows Service would be best.
The notification itself will just be a quick form that alerts the user. I'm sure most of that will be fairly easy to create. The only issue I'm wondering about is how to constantly check the database and determine a new record has been inserted.Would a windows service have a timer or something that allows me to constantly check?If it does, how would I determine a new record has been inserted?

View 2 Replies1. I have to create a file. 2. Then I want to write a string into the text file.
I can do part 1 no problem with: File.Create(strFilePath) But when I try part 2 to write to the file it won't allow this as it's still being used:
sw = File.AppendText(strFileName)
sw.WriteLine(strCode)
sw.Flush()
sw.Close()
My code in part 2 works fine on a file that hasn't just been created.
How do I release the file from the File object?
There doesn't seem to be a .close or .flush option.
