Format Time In Label From Textbox
Mar 2, 2010
I want to convert a military time was is in a textbox and convert it into a label with a standard 12hr time with a.m. and p.m.
Ex:
textbox -> label
0500 -> 5:00 am
HTML
Private Sub btnFormat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFormat.Click
lblStart.Text = Format(txtStart.Text), "hh:nn")
lblEnd.Text = Format(txtEnd.Text), "hh:nn")
End Sub
Everywhere I look they keep saying to use the format() function but maybe I am missing something.

We are designing the GUI of a microwave where a user can hit the numeric buttons 0-9 and create the time they want their item to cook. I have everything complete and ready to be submitted, but the only thing left is getting the label that displays the entered time to look like it is in a clock format.
Right now you enter the digits and it puts them like this: 95959
I am trying to get it to always enter it like this: 9:59:59

This is in Visual Basic Express 2008
I'm trying to create a textbox that'll only accept a value in the 24 hour format (i.e. "18:00" or "1800"). I've been reading up on the FormatDateTime Function but I don't know whether thats appropiate...
Also, how do I set a textbox to be fixed with two decimal places? On VB6 I could do this in properties, but I can't find an option ni Visual Basic Express 2008.

I have a textbox that will be used to type a specific time into. What i want to do is for the textbox to automatically have or produce a colon.
For example when typing in 1245 i want it to automatically appear as 12:45.
I have tried my hand at format() and .ToString but to no avail really.

i have several masked textbox connected to mysql database through a website i made, and what i'm trying to do is have these masked textbox automatically change the format what the user inputs to "hh:mm tt" so if the user inputs 6 or 600 or 6p it will automatically change it to the format to 6:00 PM.I know that i will have to use the Validated event and I've tried the Format(maskedtextbox1,"hh:mm tt") but can't seem to work. I would rather not use datetimepicker because i dont want the user have the option of using the dropdown.

I have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?

I'm returning a database query into a List object and using that list object to fill the X and Y axes of my chart as seen below. (_runData is a "List(of DatabaseTableName)" style Object filled with the results of my query.
Primary_Chart.Series(0).Points.DataBindXY(_runData, "DateTime", _runData, "UPPER_PRESSURE")
My Datetime field is returning as a Serial Number (i.e. 40116.76111) so I want to format the X Axis to display the field more readably. Enter my problem code.

There is a varchar column in the database table in this format of military time 1230 or 1750 or 1320 and that field get populated into a gridview in asp. I need to convert that string to standard time. I have tried the DateFormatString and nothing seems to work.
the asp is
<asp:BoundColumn DataField="ScanTime" SortExpression="ScanTime" ReadOnly="True"
HeaderText="Scan Time" DataFormatString="{0:hh}:{0:mm} {tt}">
<ItemStyle Width="80px"></ItemStyle>
</asp:BoundColumn>
that DateFormatString causes Input string was not in a correct format. error.
I have tried combinations of hh:mm and things like that but since its a varchar I think its failing
