I have the following function in my program:
Format(Now(), "yMMdd" & "hhmm")
in 2009 it produces 912311200 for 12/31/2009 12:00
in 2010 it produces 1001011200 for 01/01/2010 12:00
It is giving me a 2 digit year. How do I get a 1 digit year?
Ok so on my project it seems the timer is not working correctly, the interval is set to 5000 (which is 5 seconds... right?) so every 5 seconds it would display a MsgBox telling me the current date/time and then a time in a list.

I'm trying to see if the microphone on a PC is working correctly by utilizing the SpeechRecognitionEngine class.I'm using the following
VB.NET
Dim RecognitionEngine As New SpeechRecognitionEngine(New CultureInfo("en-US"))
'Dim synth As New SpeechSynthesizer
'synth.SpeakAsync("Microphone")
[code]....
When I run this code, the microphone runs until it detects a sound. If the room is silent, it never stops. At least so much as I can tell so far.But I need a way to detect when it can't detect a sound within a specified interval.I looked on MSDN and all I could find was a property called, BabbleTime. I can specify a TimeSpan that will time out the speech recognition, but from that, I can't determine if it was the timeout that caused the code to continue or if it detected sound.
I'm trying to get my decimals to display with four decimal places. The DB rounds my number to 4 decimal places, but it returns the number with trailing 0s (due to the decimal precision of the field), so something like 9.45670000.[code]...
How do I format my decimal, so that the number of decimal places is always four?
I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.

I am at college and am creating an app. however i have two main problems within my app. my app is a pizza app which will allow staff within a pizza shop to send the orders to the kitchen (this is just a listbox).but, the math doesnt work, the correct pricing isnt being displayed in the label for the orders for some reason. I have tried different ways of writing and placing my code but the result is always the same. also, i have five customers per table. if i select all the customers orders and click on send, only customer two's order will be sent. not any of the other customers, but if i just do customer one on its own, it works.

I have a context menu strip associated with a listview. Everything work just fine however one of my menu options on the context menu strip has a pop-out menu (you know, you hover over the selection, and another menu strip expands out).I can seem to get these to work correctly.
Public Sub ReleasedToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReleasedToolStripMenuItem.Click
FileEntries(ListViewSelectedIndex).Status = "Released"
[code]....
So I changed my sub to read as the one VB created, and still didnt work. So I went back to edit the context menu, double clicked "Reserved" menu items, then VB creates a sub w/o the _1 (like I had before).Also the check-box status for these menu items works fine.
I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?
i have a text box that has a max length of 5. when typeing into that text box the character input stops on the 5th character. if i set teh text property to a sting that has more than 5 characters the text box accepts the string. in vb6 i think that the text box would truncate the string to 5 characters.
does anyone know of a way to truncate, or get the text box to only accept the maxlength of the text box
[[code]I have this issue where most of the rows in the table do not fill in the data to textbox2 and any edits made in the text box when this happens do not commit to the underlying datasource.When scrolling down and back up the datarepeater different records seem to be shown each time the data on the left is correct in the standard DGV ... it's just the data repeater that doesn't work.

This is a follow up to another question of mine. The solution I found worked great for every one of the test cases I threw at it, until a case showed up that eluded me the first time around.My goal is to reformat improperly formatted tag attributes using regex (I know, probably not a fool-proof method as I'm finding out, but bear with me).

I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>

When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.
I am trying to display a number, stored in a dataset as a string, as a phone number. I have a label that Binds to a value but doesn't display the format that I passed as an arg:
<asp:Label ID="lbl005108002" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "phone number", "{0:(###) ###-####}") %>'></asp:Label>
As a test I tried to pass the formated string into the dataitem but that didn't work either. Is there something else I need to do in order to use this function?
m_Row("phone number") = String.Format("{0:(###) ###-####}", value)
The value displays in both cases as: 04152543926

View 1 RepliesI have an issue with creating a VB program. I reference files on my computer that are displayed in a webbrowser in the program. The issue comes when I install the program on another computer because of the file path. The program is looking for the files on the computer I created the program on because of the file path, instead of looking for the files within the program resource files.
For example, I created the program on Computer A and referenced File "C:ComputerAMy DocumentsHelp.txt"
Once installed on Computer B, the program doesnt display the image because it's looking for "Computer A" in the file path.How do I correct my programming so that the files are universial and can be found on any computer the program is installed on?

View 4 RepliesI'm in a beginner programming logic and technique class that also teaches us VB, and I'm working on a program that is to simulate total theater revenue, that asks for the number of tickets sold in a particular section and then displays the amount of sales generated from that section. It needs to validate that the total number of tickets sold is not over the maximum seating in that section.[code]
1) I have a warning that "Variable 'section' is used before it has been assigned a value. A null reference exception could result at runtime" in line 18.
2) Regardless of the changes I've made, I always end up getting "0" as my end result. I'm actually supposed to use the toString currency format function when getting my end result, but that was mixing me up so I figured I'd at least make sure the output is correct before I fix that part. I thought I was on the cusp of having this working but I think I'm confusing myself more and more the more I mess with it.
it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!
