i need a program that when I press a button on the form, it will display the system time continuously in a text box. I know i need a loop to do this but what I have keeps freezing my program. Heres what I have:
Sub getTime()
Dim currentTime As System.DateTime = System.DateTime.Now
Dim x As Integer = 1
[code]....
I need to be able to display 60 * x. X is going to be the time between hitting a Stat button and a Stop button in seconds. I need this to be shown until it is stopped. So i was thinking something like txtBox1.text = 60*time, but I do not know if that is correct and I do not know how to get that time. Also I am not sure how to continuously update the text box.

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.

I'm looking for an example in VB.NET of a continuously scrolling form. This would be similar to a continuous form in Access but with a major difference in that when you scroll it the whole thing moves up or down instead of the data jumping up or down to the next section. If you are not familiar with Acces, this would be a form that lists data down the form in sections, one per record, in other words, like a bunch of forms strung one after the other. When you scroll down, the record at the top gradually disappears and is replaced with a new one at the bottom.
This needs to be a form with controls, not a datagridview.Right now, I'm trying to find an example of this. I tried searching for one and couldn't find one. Does anyone know of an example of a continuoulsy scrolling multi-record form where the whole form moves in VB.NET?

View 3 RepliesI have finished constructing my form and have completed my code. I have built the project with no errors, warnings or messages. None of my code is flagged up as erroneous. Yet when I try and run my app to test it, the form does not display at all!! It did, but it doesn't anymore. The only thing I have added to my form since it did display correctly is a couple of Month Calender controls and a couple of buttons, with a piece of code behind each control.
I have not altered any properties for the actual form itself..
does anybody know how to get the datagridview to display just the time in instead of the date and time. I am tied to a downtime tracking database that has a separate date and time field. when I try to display/edit them the datagridview box refuses to leave the date out of the time and keeps appending 12/30/99 to the time field. I have spent the last 6 hours on msdn trying to find a solution and none of them seem to work. why did they put auto-formatting in a control without any way of defeating it? anyways, is there some way of displaying the long time (23:00:00) not 11:00 pm in the datagridview without it appending a date to the field just because the data type is date?
