Multiple Times To Test It Out Sometimes Adding Code And/or Changing It?
Jun 6, 2012I have written a program and have used it (in debug mode) multiple times to test it out sometimes adding code and/or changing it. After a while any code I wrote or new buttons or features I added to the form would not appear while debugging. I don't know what circumstances led to this.
The only solution I found was to rewrite my code from scratch, however, the problem came back after a while. I don't know what is going on and I can't move on without starting all over again.
VS 2010 Looping Code X Number Of Times?
Apr 3, 2011Okay, so basically I'm trying to have my application randomly select items from a (multiselect) listbox. I want the user to enter the amount of items they would like randomly selected and it should all happen at the same time. I have the random shuffle down but it only selects one song each time you click the button. How can I loop this code as many times as the user specifies in the textbox?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
Dim shuffle As New Random
Main.songlist.SelectedIndex = shuffle.Next(0, Main.songlist.Items.Count - 1)

Reuse Code Multiple Times?
Nov 13, 2010How can I tell something to use a code without completely adding it in that sub again? I have some code that will be used alot within my program. I could write a DLL, but I don't know how to use those!
Here is my code:
Dim str1 As String = System.IO.File.ReadAllText(Me.OpenFileDialog1.FileName)
Dim s2 As String = str1.Replace(".[1gs5]", "a")
s2 = s2.Replace(".[u775]", "b")

Saving Code To Reference Multiple Times?
Jan 10, 2011I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something

Looping Arraylist Adding To Textbox
May 19, 2009I'm trying to do is take each item from an arraylist, that is populated through a structure read from textfiles, then loop through them adding each result from the arraylist to a new line in a textbox. What I'm getting is that it's adding only the last item to the textbox rather than listing them, yes I have multiline set to true. Because of the potential size of the arraylist I have it running in a background worker. Once it's complete then I'm trying to populate the textbox. All the code is working fine to that point it's just populating the textbox correctly is my problem.[code]I've tried adding vbnewline, vbcrlf, cblf at the end of the statement as well as placing the text statement in both the runworkercompleted sub as well as in the delegate with the same result.

VS 2005 Reading Lines Of A File, Adding Them To Listbox, And Then Looping?
May 17, 2009I have a form with a listbox. I'm adding items to the listbox through a file that I saved.

Looping Through CheckBoxes To Get Values To Send To Another Page
Aug 10, 2011I'm trying to loop through a bunch of checkboxes I have created on my aspx page. I would like to get all the values, and parse them to a string to send to another page as post variables. This is what i have so far:
aspx page:
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox0" runat="server" /> Name</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox1" runat="server" /> Training Year</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox2" runat="server" /> Continuity Clinic</div>
etc...
aspx.vb file:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Submit.Click
Dim targetURL As String
targetURL = "report.aspx?"
' This is the part i can't figure out.
' For Each checkbox on page
'if checkbox is checked
'targetURL &= checkboxid & "=true&"
End Sub
My goal is to build another page that will then check these values using Querystring variable, and build a listview out of them. (a report page, that basically lets the user select checkboxes of the columns they want to see on the report).
Looping Through DataTables And Appending Values To A String
Apr 24, 2012I have been out of the VB game for awhile and am now trying to catch up to VB.NET. I know my current solution probably has a more efficient way of doing what I want, such as using LINQ or something. But, I am start at the bottom and working my way up. I essence I have 1 table controlling which columns get added to a working string, that I will eventually export into a text file. My first table has 3 columns(ID, String, Processed). The ID is the index or primary key and the string is the data I need, and Processed tells me if I have extracted that string yet or not( 0 for no and 1 for yes)...
My main problem is checking values in table 1 where I need to add the string. Of course my problem might be deeper in how I am even returning the values from the datatables.

Word 2007 Adding Adding Values To Combo List Box
Jun 7, 2011I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?

Looping A Collection Into Multiple New Filenames - How To Speed Up
Apr 6, 2010i have the following snippet of
For Each tempstring In SourceDataCollection
LineToFieldsTemp = Split(tempstring, ",")
LineStringWithoutFirstEntry = "" 'reset the linestring
For i = 1 To UBound(LineToFieldsTemp)
[code]....
essentially what i'm doing is to read through each item in a collection of comma separated variable strings. the first variable in each string is appended to a master filename and becomes the NEW filename to which the entire string will be appended. this is a way to split a CSV file into multiple files using the first variable in that string.
the trouble is that this is doing a LOT of writes to potentially a LOT of files, the IO is taking forever. is there a way to buffer this data until the end, then write it to a disk? be aware, the filenames and total number of files to be created is UNKNOWN at the begining of the loop. it just creates a new file each time a unique first column ID is discovered.
Threading: Multiple Looping Threads Where They're Guaranteed To Run?
Jul 12, 2011When the program starts, it checks for the amount of threads the user wants to use to download files with. The threads are then created. When the user chooses a file to download, the threads begin grabbing the file until it's fully downloaded.The problem is, some threads stall right from the start, & just sit there doing nothing.The global work variable is Sync-Locked, then quickly released by each instance, & to my eyes, there is nothing wrong.They are all instances of the same class, & do the exact same thing, so why is it that some run, & others don't?VB.NET is the programming language. They are looping Background workers.I would really like to know why some run, & others don't.btw... they have quick non-blocking sleeps, as well as blocking sleeps to allow others the chance to run (proprietary non-blocking DLL).So all i'm left to think on is that Microsoft's process queuing has some type of bug going on in there someplace....or is there a way to do multiple looping threads where they're guaranteed to run?
View 2 Replies.net - Singleton Initialized Multiple Times
Jun 27, 2012So I took this from an example. GetInstance() is called from hundred different places in my program, and when I debug, the line "Prog = New Program" keeps getting hit for each of those calls. Which I thought was exactly what should NOT happen.. Or do I have some fundamental misunderstanding?
[Code]....
It seems the "New" sub triggers a number of calls to Program.GetInstance, before the first one completes. This is due to me earlier having lots of shared public objects in this class, which are no longer shared since the class was made singleton. And these objects, when initialized, calls the Program class for reference to other of it's objects.
