Some Code Not Executing From Inside EventHandler?

Feb 19, 2008

I'm having a really weird problem with my current project in Visual Basic 2005.To make a long story short, I have an EventHandler subroutine (Clock1_tick) which triggers on the Elapsed event of a Timer (Clock1). Some, but not all, of the code within the subroutine executes correctly. Some of it doesn't execute at all, even though the debugger shows that each line of code is being read.

The overall details of the program aren't really important, but within the program I have a VB class file which can be instanced via the "New" keyword and contains a series of functions, subroutines, and properties... a typical class file. The class file is for managing sound channels..The frmMain includes a status bar with a label to display the program's current status. It also includes a public sub which recieves a string and sets the text of the status bar:

Stopping While Executing A Block Of Code

Oct 10, 2010

I'm trying to replace text using this method:

Add each characted to a String list (List(Of String)), execute the replace function for every type of character (for example: Text = Text.Replace("A", "0AA") Text = Text.Replace("a", "1AB")), but there's a problem: it replaces the text, but it replaces those replaced characters too, so when I replace "A", it will result something like this: "0AAB AAA 0AB"... (a long text)), and then add the characters to the result string

how make the application stop and start the replacing of the next character

I'm trying to use this code block:

Dim ReturnedString As String = GivenText
Dim ListToEncode As New List(Of String)
Dim curr As Integer = 0

VS 2008 Code Not Executing In Right Order?

May 13, 2009

i seem to be having issues with my simple count down project. The count down work how I want it, there is also a pic of a rocket that move up when the count down button (Button4 - the form was set up in class as a quick example, so there was no need to name the buttons) is pressed. The problem is that the count down "10....1...Blast Off" shows after the rocket has moved up, I want the countdown text to show, then the rocket to move.The countdown is outputted to a ListBox.Here is my code thus far: (I have re-worked is a bit, starting to look messy)

I am not sure if I should be doing it as a function, that was just one of my attempts to get it to output everything in the right 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

Code Executing To Fast For Lbl Text Change?

Aug 23, 2011

When you click a button on my form, it opens a folder dialog box & gets the selected path, then changes a label's text to state that it's starting to process the directory then it goes ahead & opens a new streamwriter & continues on into my other sub for listing directories..roblem is the label isn't changing before it does it's processing, I figure that is because it's processing to fast to actually display the text. Even if processing the directory takes a minute or more the label won't ever change, which should have happened before it started processing the directory.

Executing A Sql Command - Number Of Values Provided Must Be Equal To The Number Of Placeholders In Query?

Aug 11, 2010

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET

Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:

Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})

Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

Disabling Button Before Executing VB Code To Prevent Duplicate Records?

Feb 15, 2012

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases.After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:

On page load:
If Me.Page.IsPostBack Then
'lblDetails.Text = "disabled"

[code]....

I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:

Code:
<script type="text/javascript">
disableSubmit(frm) {

Parameterized Query : Works With Execute Query But Not In Code?

Oct 22, 2009

I have created a parameterized query in my tableadapter. Here is the SQL:

SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....

When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:

Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....

why the query works in the Query Builder but not in the code?
