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
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.
View 1 RepliesMVC3 VB.NET application. I have the below section of code in a function. This code is supposed to only fire if the handout1 is not nothing. But for some reason it is going into the then block when the handout1 is nothing in the database... I have tried a hundred different ways of checking but it is still trying to run that line of code even when there is nothing to assign to it....

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 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?
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?
[[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.

I have an AsynchFileUpload on my page and for some reason when I try to use it to save the file to the server it falls.

It seems that the filename is being lost somewhere after the button is clicked, or just never stored

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 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.
what is the code for finding the shortest,average and longest sentence form the text box

Description] "Every hundred years, the dark vampire known as Dracula resurrects and terrorizes the land. A vampire hunter named Simon Belmont bravely ventures into the Count's mansion in order to defeat him. Along the way he'll have to defeat skeletons, bats, fishmen, medusa heads and other evil creatures.Castlevania is a side-scrolling platform action game. The player taking the role of Simon Belmont is able to jump and crack his whip directly in front of him. Power-ups can be obtained by defeating enemies or by whipping candles that appear in the castle. One such power-up increases the power and length of Simon's whip. Different weapons can be gathered which consume hearts when used, these hearts can also be collected from monsters and candles. Additionally, some walls will hide secrets such as the health-restorative turkey or the Double and Triple shot abilities for the weapons Simon has collected. At the end of each section of the castle is a boss, which must be defeated. Progression through the castle eventually leads to a confrontation with Count Dracula himself."

Is there any function similar to string range in vb.net 2.0? What I am try to achieve here is to extract some text from a string with unknown length. eg. given string = text text text mytext1 text text text text mytext2 text text text text expected string = mytext1 text text text text mytext2 So I have the indexes for "mytext1" and "mytext2". I am looking for a way to get the text that wrapped in between those two strings or indexes.
