Asc Command Not Working Correctly

Dec 13, 2009

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.

Select Command Not Assigned Correctly

Apr 21, 2012

My SelectCommand.CommandText is:

dtaadpPoints.SelectCommand.CommandText = "SELECT TOP 1 * FROM PointsTrans WHERE UserID=" & UserID & " ORDER BY PointNo DESC"

This should select the top row from the table PointsTrans where the UserId is what has been declared earlier when sorted in descending order.

Asp.net - Update Sql Command Not Executing Correctly From Vb Code

Dec 5, 2011

In my application, I have a call for an update to a table on my database. I know that it is executing because I get a 1 returned when checking the number of rows affected but when I look on the DB the value is not updated - I have refreshed and still no update. Here is the code, taskgrp_template is type bit and taskgrp_id is type integer. Id is also set to the correct value, as the result of my tracepoint - results listed below code.

mycmd.CommandText = "UPDATE p2_taskgroups SET TASKGRP_template = 1 WHERE TASKGRP_ID =" & id
rowsChecked = mycmd.ExecuteNonQuery()

Tracepoint result: the value of id is 55 and the value of templateCheck is 14 the number of rows affected was 1

.net - Creating An (VB) APP And It Isnt Working Correctly?

Apr 11, 2012

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.

ContextMenuStrip Sub-Items Not Working Correctly?

Feb 13, 2009

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.

LINQ To SQL Update Not Working Correctly

May 11, 2009

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?

Text Box Max Length Not Working Correctly?

Mar 16, 2010

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

HTML Tag Replacement Regex Not Quite Working Correctly?

Sep 14, 2009

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).

My functions:

Dim findTags As String = "</?w+((s+w+(s*=s*(?:"".*?""|'.*?'|[^'"">s]+))?)+s*|s*)/?>"

VS 2010 See If The Microphone On A PC Is Working Correctly By Utilizing The SpeechRecognitionEngine Class?

Nov 15, 2011

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.

.net - HTML Input Not Working Correctly With AJAX Update Panels Used Else Where On Page?

May 20, 2010

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>

[code]....

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.

DB/Reporting :: SQL Command Builder Does Not Seem To Be Working

Mar 15, 2012

I'm experimenting with the sql command builder and it seems to do nothing when trying to update existing rows. If I create a new row and then add it then it works fine but I cant seem to update an existing record.

Heres what I have at the moment

Code:
Dim strConnection As String = "Server=myServerSQLExpress;AttachDbFilename=C:databasepath estdb.mdf;" & _
"Database=testdb; Trusted_Connection=False;User Id=sa;Password=test;"

[CODE]...

But I'd really like to find out why its not working when using the command builder. I'm working with VB.net 2010 express and SQL server express.
