I am developing a software for tracking the time and attendance for employees. I am learnt the best way for me to be able to capture this information is through the use of a biometric device. But right now my problem is how do i integrate the biometric device in my project. What do i need in order for my Vb.net to be able to recognize the biometric device so that i can record the details captured into the database.

Using the datetime function to determine lapse time. (Subtracting one from another.) Then placing the answer into two text boxes one with the date and one with the time, later to be placed in a database as two seperate fields. Was thinking I could convert the date/time to a string if necessary then use simple stringmanipulation.... however fear it won't be good programming and will effect resources and end program speed.

I want to save datetimepicker value of date and time in two separate text files. Currently, when I select a date from datetimepicker and save it in a text file it saves both date and time as below:
5/11/2011 8:25:06 PM What I would like to happen is as below: Datefile.txt saves 5/11/2011 Timefile.txt saves 8:25:06 PM Alternative solution that can work for me would be, if the time (only the TIME) can be modified after saving as below: saved datetime into text file is 5/11/2011 8:25:06 PM
How can I modify the time only to say 12:00:00 PM. By doing so I would like to keep time as 12:00:00 but date can be changed by the user using the datetime picker.

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

There are two forms. For the form1, the view is 1 textbox and the button. For the button in the form1, when it is click, it will go to the form2 which consists of the datagridview. After select the numbers from the datagridview, it will go back to form1 and display it in the form1 textbox. But I want to separate it with a comma. Here is the code in form2: Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..

I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

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

using VS2008, targetting framework 3.5I have a rather complex UserConrol which does some of its own rendering.I display this UserControl on a form.Opening that form in the Designer creates an instance of the UserControl in the Designer, which tells me a NullReferenceException is occurring in one of my rendering methods.I have attempted to correct this by making alterations to the UserControl's default constructor, but have not found success.

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.
