When I setup the event using DDay.ical I can successfully send the events to a user's outlook. The problem arises when multiple events are setup at the same time. When this happens all emails are updates to the original task, not new tasks.
I tried adding a name to the event using the .Name property, which results in the event email being an unsupported calendar invite.

View 2 RepliesI am trying to calculate the time difference between two points in time. I am using: Environment.TickCount.I set a long variable to the Environment.TickCount and then a second long variable to Environment.TickCount at a later point in time. I then subtract the second long variable from the first long variable, yet an incorrect difference is returned.

I have a value which is milliseconds, I did some experimenting, and with my very limited math skill I came up with this:
Dim val = _Memory.ReadValueFromAddress(hProcess, timer_addr, 4)
Dim seconds = val / 60 Mod 60
Dim minutes = val / 60 / 60
I don't even know what will happen when the hour counts down,
I'm new to VB and I'm so confused when using DateTimePicker. To be more specific, I have 2 inputs and two of them are Booking Start Time (BST) & Booking End Time (BET) (using DateTimePicker and set them as Time ). I should allow users to choose any time (including Minutes and Seconds)for BST (just need before than now) and BET. BET must be greater than BST at least ONE minute, but still also ensure it less than now (else it should appear a message box to tell specific problem). Then,system will calculate how long it is.

I am sure there is a better cleaner way to do this but again I am just starting to feel VB.Anyway, what I am trying to do is get the calculations to work in real time, the form loads with the default radio selection and when the user click the controls, the prices starts to change like add and subtracts.Using the button is also an issue since the increment on the check boxes goes up by one even when the user click on another radio button.[code]
View 14 RepliesIm using the express edition of VB.Net to do my project. I have several threads in my program which run fine. However, im stuck at this problem. I have a button in my form, which if I click I will call ThreadA (works fine), If i keep it pressed for more than 2 sec i need to call ThreadB (doesnt work), and if the time is more than 2 min, i need to stop and send a msg to the user. I have tried the timer to calculate the elapsed time, so the tick function would call the thread. BUT this doesnt work... Im not sure what do to.
View 2 RepliesI made a sort of downloader program in Visual Basic 2010, and it downloads okey. It reports the full size of the file, and how much that has been downloaded right now and the percentage.
But, a function that i am missing is to show the user how much time is left on the current downloading. I have searched for it, but i couldn't find any solution that would work.I should also mention that i use a webclient for the actual downloading part.
I've written a lot of code in VB6 and VBA but for some reason, I can't get my head around how to do it in VB 2008 Express.I'm trying to write a program that takes the time distance from an earlier time to a later time, in minutes maybe or even seconds, and use that value to calculate a percentage for a progressbar control.since I'll have multiple events, I will need multiple progress bars. I've figured out how to dynamically add them to a form, and how to update them via a timer. Even learned how to assign an event handler and how to target a progress bar in the array. All is good there but...Well... the parameters for each instance are start time and end time. With those two values, I'm hoping I can calculate where I am between those two points and feed that value to the appropriate progress bar. I just can't seem to figure out how to calculate time values from an input from say, a text box.
I have a text box for each instance for start time, something basic like "11:42 pm" and end time in the same format. Once the timer is started, I want to be able to calculate how far I am from the start time, how far to the end time, and use that to feed the progress bar as to the percentage of completion.Again, I figured out how to add a set amount of controls at run time as per the instances of timers. Of course, I'm only using one timer control to update the form, but using it to process the information and update the progress bars.Later on, I want to use a database to draw the timer data from, but for now, I need to get past this simple hurdle.I THOUGHT TimeSerial would do it for me... going back to my VBA work, you had one timeserial, and another, and you could use the result of one minus the other and then format the result. Even use that number to figure out hours, minutes, seconds. I can't seem to figure out how to do that with Visual Basic 2008 Express.
