View 19 RepliesI'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 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.

View 2 RepliesIn 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.

View 2 RepliesI 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:

If Me.Page.IsPostBack Then

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:

Or am I missing something here?Is there a way that Code of an Object is executing even when the current Object is Nothing?

View 4 Replies"add controls at runtime" how to add code to the controls. kinda useless with no code, ehh? all results only told me how to add the control, that's it. well, this result is different. i will teach you firstly how to add controls at runtime, then how to apply code to them at runtime
Firstly, add the controls:
[CODE]..............
Now run it. do you have a button on the form? if yes, excellent. if not, you made a mistake. try again now how to add code? you may have noticed that when you double click on any control, it says private sub button1_click(blah, blah, blah) Handles button1.click where it says handles button1.click is what determines when the code executes under what event for what control (in this case the click event for the button1). this won't work when adding code at runtime. did you notice in the above example i added a with event, and addHandler? this is what creates the handler (same as Handles button1.click)
Now we add the code for the runtime control
[CODE].........
Above, the addressOf button1_click tells the program to execute the sub button1_click when the button is clicked on (as determined by .click) but i know what you're thinking! your thinking "why would we even BOTHER doing this at runtime? isn't it easier to do it at design-time in the first place?" yes it is, providing your not writing a plugin. plugins are code based, not GUI (also reffered to as WYSIWYG). to update existing forms using plugins, you need to use this method.
