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)
[Code]...
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.

One button is checked server connection, other should execute query for server table.Connection code is working, as I have set two messages, and getting successfull message. Second code is not working, as nothing happened when press button. Sql statement is very simple, and it works if I run it manually.[code]

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:

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

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

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.

I would like to ask some questions related some functions i want to make in my program:
1. I am using this function in order to get a the item code from the database Long.Parse(myReader(0)).ToString("2200000000000") the result i get is: 2200000059091. The form that i want the resultset is
22 (fix value) + item code (6 characters right justified) + 00000 (fix value) 2205909100000 how should i change my code to obtain this result?
2. The programs every time it runs creates a text file which i also attached it plu1.txt, when i try to open it with notepad i see all the lines justified, on the other hand when i open the text file with Wordpad or ConTEXT the lines are not fixed, others are longer others are shorter? What should i change in my code in order to have every line fixed lenght... The code i am using is the following
Dim myReader As SqlDataReader = myCMD.ExecuteReader()
Dim fNextResult As Boolean = True
Using myWriter As IO.StreamWriter = New IO.StreamWriter("c:everest
[CODE]...
3. third and last question is that my program every time it ends show up a pop up menu which says "Text is created." Instead of this i would like to create a file lets say log.txt and every time the program runs, it will overwrite on the log.txt file a line like this: system date + Text is created + with X lines (where X are the lines of the text plu1.txt) ex. 26-10-2009 14:56 Text file created with 15 lines

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) {

I would like to execute an external program within powerpoint after the presentation has loaded so i can see if its working. In short my overall objective is to execute the external program which will open up the command prompt and use the sendkeys method to sendkeys to command prompt which help it to run a script at the correct time (which is after presentation is loaded).

In ASP.Net Web Forms there are cases that I've come across that create order dependent code. As an obvious code smell I'm looking for solutions to solve this problem.
A pseudo-code example would be: Calling Code :: Page.aspx
protected void Page_Load(...) {
var control = LoadControl("ControlX.ascx");
// Ugly since the control's constructor is not used by LoadControl
control.SetDependencies(...);
[Code]...
LoadControl has two signatures, the one used above accepts a string for the control classes physical location and correctly creates the child controls. Whereas the second signature accepts the control class as a class type, and any parameters for the constructor, however the child controls are not created as detailed in TRULY Understanding Dynamic Controls.
So how can I eliminate this order dependency in the cleanest way? My first thought is that if I dynamically created the child controls in ControlX, but then that can be cumbersome for larger controls.

I am working on an application that requires buttons and links to be added during run time, it's a bit like a flow chart. The buttons are used to display information similar to a multi line text box, but I also use the click, double click and mouse events for these buttons. The links are drawn as label controls. My problem is that I want to control the format order of these controls with the buttons always being on the top layer and the labels one layer back so that when labels are added they aways pass behind the buttons. If this was done at design time it is very easy to use the menu Format > Order to get overlapping controls displayed the way I want. But, the controls placed on the form at run time do not have a Format or Order property.

I am working with a datagridview and 2 text boxes.TextBox 1 is for entering time of the day and TextBox2 is for entering time duration in that order. After TextBox2 looses focus I am converting the times into index numbers in my DGV1 and filling the selected indexed rows with some data. The data then is checked and if there are issues message is display prompting the user to correct it. However, all my codes for checking the data and selecting options are in the DataGridView1 event handler:
Private Sub Datagridview1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MouseUp
Is there a way to execute one Subroutine from another Sub. Sort of simulating a mouseup click programmatically ? Correction: there are 7 sets of those TextBoxes representing 7 days of the week. I am trying to avoid duplicating all that error handling codes in all 14 boxes. I have read that MouseEventArgs are protected so it may not be easy.
