my Vb 2010 midterm project is due a 8am ( > 2 hours). I have coded almost everything I need. Just before I was about to submit this, I noticed in the instructions that hours needs to be included as well. I have been trying to do this for about 2hrs now, and just can't seem to get it right.
[Code]....
Title says it all, I get a format exception saying that the input was not in the correct format.
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If Integer.Parse(TimerBox1.Text) > 0 Then

What I need to do to make this code work for hours as well?[code]...
View 6 RepliesThis is what I have so far.

The first part (Label 1 + Timer 1) works fine and it counts seconds but I want it to count minutes and hours too.
I am working on code for a countdown timer, where 2 labels (Minutes label = label6 and Seconds label = label7). I have tried for a long time to try and get this to work, and it has to be "Hours:Minute" format. I will add below the awful start I have made
If Label7.Text = "1" Then
Label6.Text = (Label6.Text) - Val(1)
ElseIf Label7.Text = "1" Then
Label7.Text = "59"
[Code] .....
There is lots of bugs, such as the last minute is cut out, and it is just buggy, the user must be able to select a time/duration for the timer to work, and also this must be able to change every time the time reaches 00:00.
I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.
View 2 RepliesI have 4 textboxes Hours, Minutes,Seconds,Milliseconds. When textboxes values are set the count down begins. So far everything works except the milliseconds
Timer1.Tick
Timer1.interval = 100

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 4 RepliesI'm creating a microwave oven and I'm in need of assistance if anyone is out there? I have 2 problems : my buttons dont work and I believe it's because I have two of the same name variable in local and global scope because the local one hides the global one in its scope. You have two variables called timeIs. My output is lblOut, everytime I try to change the names they underline in blue so I can't even check the start button. And also DisplayTime() to print 0 because it deals with its local variable.
Public Class frmMicrowaveThree
' contains time entered as a String
Private timeIs As String = ""
[code]....
The user can choose it, like this.
Dom = Sunday
Seg = Monday
...
Sex = Friday
...
So the user will choose the days and the hours for my program open and execute the progress that I programed on the button START, so how to make it start on the days/hours that user wants? Btw the program will stay on the Notification area.
Here's the
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Hours >= 1)
If CanTest Then
[code]....
However, when I change it to 65 minutes instead of 1 hour, it acts up. The time until next question starts going up instead of down... The only thing I changed is 1 hour to 65 minutes:
CanTest = CanTest OrElse (DateTime.Now.Subtract(LastTest).Minutes >= 65)
If CanTest Then
If InputBox(Question(Cur), "Question #" & cur.ToString("###,##0")) = Answer(Cur) Then
[code]....
i am working on a microwave app its very important anyways ill give up what code ive got so far and such but when i try to run it i get this error message: Visual Studio cannot start debugging because the debug target Microwave.exe is missing Please build the project and retry or set the OutputPath and AssemblyName properties appropriately to point at correct location for the target assembly.

I have created a 7 day timer in a VB form that is to be part of a larger project. It has 14 date time pickers set to hours and minutes only in 24 hour format (1 on and 1 off per day), 7 checkboxes, 7 radio buttons, 2 textboxes to display day of the week and current time and a few buttons. As a standalone project, this works well
View 6 Repliesthis is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

Has anyone else had issues with Visual Basic 2010?My visual basic program has been running fine for months but recently every time I try and load a project (any project) the program freezes, then I have to close it down and reload, every time I load Visual basic for the second time I get the following error:
HTML
An error was encountered while opening associated documents the last time this solution was loaded. Document load is being skipped during this solution load in order to avoid that error.Plus when trying to run a project in debug it takes ages to load (around 5 minutes) this has only started happening recently, projects were loading in seconds.
A colleague has written a useful tool. He wrote it as a standalone tool, but it works even better as an includable dll, though it needs a bit of other functionality for it to be a really good drop-in component. What I am wondering is whether a project can be compiled as both an exe and as a dll?
There are alternatives, such as having a dll version and an exe version, since the dll version needs to include a few different methods that the exe version doesn't need, but this alternative sucks, since it would mean changing two sets of code.
Another alternative is to build the dll, then change the exe to be a project that references the dll....and does nothing other than calling one method in the dll. That kind of sucks, too, but not as bad.
I want to be able to use his module in some of my programs, and it really should be built as a component rather than a standalone app, but I want to know whether there are other options that I haven't considered.

I require the Login button on the User app to be enabled at a certain time during the day, and the Admin will specify the time. How do I go about achieving this? I have a database as wellDo I save the time in the Database that the Admin enters, and then retrieve the time from the database when the User app is running and compare the clock time on the User app to the time from the database (I will retrieve the time when the User app starts)
View 9 RepliesI have a sub routine that connects to a database. If the database is unavailable it takes about 45 seconds to timeout, even though I used connect timeout=10 in the connection string.
So I figured I would try using a timer. This is how I have it
Private Sub SQLConn()
Timer.start()
SQL.Open()
Timer.stop()
Private Sub Timer2_Tick
(this is where I need to put a command to stop the sub SQLConn)
I have the timer set at 10 seconds. Unless there is a better way to do this what command can I use to stop the connection or the sub?

I have a VB.NET project in Visual Studio 2010 for an Excel Add-In.I use the "My" namespace,and in general it seems that the "My Project" folder contains configuration information about the project.My problem is that I need to change the name of this folder, because my version manager system won't accept spaces in file or folder names.Edit: There is a hacky way to do it, by renaming the folder and changing all references in the .vbproj file.However, the may work for a command line generation, but it won't work the next time the project will be opened in Visual Studio. The IDE will create a new "My Project" folder, and complain that it can't find the settings in it.
