i am creating an Alarm clock application that requires user input to deactivate the alarm. However is there away i can display the inputbox for a limited time only say ( 1min) if no user input is entered after that time then the input box is closed. [Code]
View 2 RepliesI have an assignment that asks me to:
1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?

The goal -- use VB.Net to write a windows forms application that responds to a limited set of voice commands after the user says a keyword, (such as "Wake Up"). I have the following code I am using from another site but I am getting an error I do not understand (nor do several others who posted comments at the same site.)

If I had any understanding of how to create a grammer file I MIGHT be able to avoid this error completely, since I am only interested in a few voice commands (maybe 30), not the whole 60,000 word dictionary.

Dows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.

I caused the VB.NET2008 IDE to do something extremely odd and unintentional with some code I was writing. As some of you know, I mostly write programs for industrial equipment. On one of our products, I needed to make certain forms automatically close after a timeout period. To do this, I began programming a usercontrol with a Timer on it (interval = 1000) and a ProgressBar. Timer.Enabled was set to the Enabled event so I could toggle it. When the control counted to it's timeout period, it would call Me.ParentForm.Close
So I build my project, and drop it on a form in the IDE and I see it begins counting! Huh... I had no idea timers were active in the IDE. I wonder what happens when it hit's it's trigger? I figure probably nothing since Me.ParentForm was actually the designer. When it triggered, the whole IDE crashes without save. I tried it twice now. Here's my

I am trying to create what I am sure is a simple program to add hours to convert UTC time. I want to type in a UTC time and have it convert for every state in Australia. [Code] Now that works fine however when the conversion goes past "midnight" it then shows the date and time. I have tried about 50 different things but cannot get it to remove the date when the converted time passes midnight. [Code] The string was not recognized as a valid DateTime. There is an unknown word starting at index 18.

This works perfectly, but every first time the app start and I open the second form, on my primary screen (right side) I see the border of the second form. When I click the button again, the form is hidden, and when I click it again, it appears again but then the border is gone.

We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?

View 3 RepliesWe need to put a firewall in between our servers and a couple of clients. To do this we need to limit the number DCOM ports available so that we know what ports to open on the firewall.The question I have is do we need to limit the number of ports on all the machines inside the firewall as well as outside. This would cause an issue as we have lots of machines which would need to be modified.If DCOM has the intelligence to negotiate on port 135 which port is available on both machines which need to communicate, we will only need to modify the 2 machines on the outside of the firewall.

View 12 RepliesI am using a panel control in vb.net (2010) to build a timeline of images. These are very small images (320x180) and I am running into a limit of 240. While the panel does not complain when I add more - it will only scroll to the 240th one.[code]...
I am counting on some of the built-in functionality of the panel in autoscroll mode (being able to bring any of the thumbnails into view), etc. I am certainly not averse to purchasing a third party control for this. I really need to be able to display 1000 or more thumbnails!
I was reading an interesting article here and it made an interesting point about the 'case' statement in vb.net vs the 'switch' statement in C#, which I've pasted below:The following Visual Basic Select Case statement can't be represented in C# with a single switch statement:
Dim Condition As Integer = 55
Select Case Condition
Case 1, 3 To 5, 10, 12, 14, Is > 50
[code]....
I've always found the switch statement in C#, with dropthrough and consequentrequirements for a break in each case, to be a bit unwieldy. Is there any reason they haven't enhanced the switch command to allow these situations? W
EDIT AFTER CLOSE: I'm surprised this was closed, really. With the number of extension methods and helper classes I've found online for other things, I thought an enhanced 'case' would be a good chance. I somewhat hoped a luminary such as Jon Skeet may have commented on the background reasoning, rather than the individuals below who've obviously thought 'religious debate' as soon as more than one language is mentioned.
I want to create a dial which is basically a circle that I can drag around in a circular motion. Ive looked at using the code in an earlier post which allows you to drag items around a screen but I cant figure out how to confine the movement so it only allows the user to drag this circle around in a circular motion. Any coordinate altering I do just looks snappy.
