Scroll The Text Inside The Label For Anything That Is Longer Than The Label Width?

Apr 5, 2009

I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.

Sub f1timer2tick()
Dim g As Graphics = f1l2.CreateGraphics
Dim s As SizeF
If f1l2.Text.Length > 19 Then

Setting Text Of Label Added At Runtime?

Apr 18, 2011

I've added some Labels to a form at runtime using this

vb.net
Dim x As Integer = 25
For i As Integer = 1 To word.Length

[Code]....

Now, I would like to add text to one of them, but I'm not sure how. I thought by setting .Name I would simply be able to write something like lbl4.text ="A". But, of course, because the Label has not been created yet, this is not possible.

Also, I'm not even sure if .Name is working the way I think it is. I was hoping that it would name each Label consecutively: lbl1, lbl2, lbl3, lbl4...etc.

Am I naming the Labels properly? And how would I add text to one of these Labels?

Multithreading: Reading/setting Variables, And Passing Variables?

Mar 8, 2011

Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.

Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?

Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?

Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

Setting Variables To Store User Setting For Applications

Feb 13, 2012

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

VS 2005 - Localization In Windows Application - Label Which Text Is Merged With Some Variables Or Object Properties

I've implemented the localization in my windows application with no problem for the label or command button which have a fixed text.

So, how can I set (if it's possible) the localization for these labels? I've this kind of assignment in modules and not in the form. It's possible to set a resources file also for modules?

VB 2008 Why Are Static Variables Set Equal To 0 In The Declaration When 0 Would Be The Default Value Of The Numeric Variable

Why are static variables set equal to 0 in the declaration when 0 would be the default value of the numeric variable anyway when it's first declared? Not including the "=0" in the static declaration seems to work with no problem.

I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages.

For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then

.net - LINQ-to-XML Selecting Tags Inside The Root?

May 12, 2012

I'm trying to learn the query structure. I have the following XML:

<?xml version="1.0" encoding="utf-8"?>
<list>
<item>
<due>07 May 2012</due>

And I'm trying to delete <item> elements with a query:

Dim DeleteItems = From e In Root.Elements("list") Where e.Element("name").Value = Text

However it isn't working. I think it's trying to select tags called <item> in the file's root, however it needs to be selecting <item> tags in the <list> element - which I don't know how to do.

Setting Parameter Values To Equal DataColumn Values?

Apr 23, 2011

I'm trying to assign some parameters for a stored procedure with some values that are stored in a data table. in the code, I can set the parameter values to the data table, and give a column header or index without issue, but when it tries to execute at runtime it bombs out.the error I get is a variation on "Failed to Convert Parameter Value from a DataColumn to a String" depending on exactly how I try to assign the value.the data types are all correct elsewhere in the code.

my code for this bit is

Try
ConnectionAttempt.Open()
Try
With NewYearCommand_Dates

[code]....

other things I've tried to get this to work are all variations on the .Value=dates bit, such as

.Value=dates(0) (so using column index)
.Value=dates.columns(0) (again using column index)

I've also tried declaring variables, and setting their values to the values in the columns, but the code returns an error saying that "Value of type 'System.Data.DataColumn' cannot be converted to string".I should point out that i'm doing this for 3 tables at once in this sub, 2 of them will only have a single row of data, but the third has an indeterminate number of rows.I'm afraid I don't know what else to do. I'm lead to believe by my mate and my lecturer that this should work, and of course it will work, but the evidence says otherwise.

Setting Variables To Use As File Names?

Sep 10, 2009

We have this current VBA program to help us with AutoCAD via the use of a template excel sheet.The setup we have created works well; however occasionally we have two drawings per folder, which often results in, two templates excel sheets of the same name, one overwriting the other. how I can set the active drawing name in a variable that our program uses to check for, then if not present that it creates a copy of out template and then saves it as the active drawings file name which was set as the variable

This would allow our program to locate the associated excel sheet by name then save it by the unique drawing name and prevent existing excel files being overwritten if in the same folder.

;===CODE STARTS HERE===
Option Explicit
Private Objexcel As Excel.Application
Private ObjWorkbook As Workbook

Quick Technique Of Setting / Saving Variables

Dec 26, 2011

I know this is a VB.Net messageboard, but it can work with in all languages. Is there a quick way to complete a line (sample code):
//Setting variables set 1
a = e;
b = f;
c = g;
d = h;
.....

//Saving changes set 2
e = a;
f = b;
g = c;
h = d;
without having to type everything out...A technique using EXCEL or Notepad....Find and Replace. This would save a lot of time coding and becomes pain in the butt when you working with many variables.
