I have several sets of similar objects (labels, progress bars) on a form in Visual Basic 2010 on Windows. In my code, I have collections that contain data, which needs to be pushed into the value/text property of each.
I would like to get a solution similar to PHP in that I can assign values somewhat like:
For ID as Integer from 0 to count(collectionExample)
lblExample{ID}.Text=collectionExample(variableID)
...and as such to loop through so each of the different lblExample's were updated to their corresponding value.
The issue I have come to is that I cannot seem to reference an object on the form using a variable. I have also tried using something like
CallByName("lblExample" + variableID, "Text", CallType.Set, exampleCollection(variableID))... however I still can't combine the string and variable to reference the object.
Any solutions on referring to objects in VB2010 by combining a string prefix and a variable string identifier, similar to PHP's $variable{$variable} approach?
Edit: Windows Platform
For I = 0 To 10
If Items.Count = 0 Then Exit For
Dim T As New Thread(AddressOf Thread)
T.Start(New Object() {"Test", "Test"})

I am not sure if this makes sense or not,but I need to process raw text(without any encoding?) that I retrieved from a file recovery application "PhotoRec"
With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.Here is what I am using to process the file:
[code]...
I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "currentbyte".So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

View 7 RepliesI'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?
Going from VB6 to VB10 I find VB10 has much easier ways of doing things, like getting command line arguments, getting all subfolders, etc, the hardest part is knowing what commands to use. Is there a better way to detect if a string ends with certain text? I'm doing it like this....

I'm outputting a number of variables to a text file and each field needs to be in a specific place.For example:I have a string that is varying in length, but will never be more than 5 characters. The string has to end on the 8th character of the line. Is there a way to write the string to ensure that the string ends at a specific place on the line, regardless of the length?

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?
I'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?

2) A start time, for example: strStartTime1 would have the value of 9:45
3) An end time, for example strEndTime1 would have the value of 18:00
