I have a string like "pen pencil table desktop watch" I have to format it like "penPencilTableDesktopWatch" ..... like convert to camel casing. Is there any method of string or string builder in which I can do it in one line ? ... (without splitting and formatting each string and concatenating.)
View 4 RepliesI have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
[code]....
Is there any specific reason why camel casing examples often start with a lower case letter?
E.G:Dim btnSave As New Button
'as compared to.>>
Dim BtnSave As New Button
Is it to make a distinction between the ( object / variable ) and its TYPE?
Why then does the IDE not add items starting with a lower case letter if lowercase initial lettering is more common or more accepted?
Anyone know of a nice efficient function that could convert, for example:
HelloWorld --> Hello World
helloWorld --> Hello World
Hello_World --> Hello World
hello_World --> Hello World
It would be nice to be able to handle all these situations.
Preferably in in VB.Net, or C#.
Dim a As String = ""
Dim x As Integer = 0
Dim y As String = ""

I have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?
View 2 RepliesI have a filename in a string. I want to split the given string into 2 (1 is filename without extension, 2 is only extension) strings. Then add _dev to the end of first string and concatenate with 2nd one.
ex: Dim name as string="abc.txt"
Dim finalName as string
The finalName should be like this "abc_dev.txt"
I am supporting an application, which uses lots of String concatenations and I believe this is the cause of a memory leak which eventually causes an OutOfMemory exception. Please have a look at the code below:
Public Sub ConcatenateString() As String Dim Test1 As String
Test1 = "Hello"
Test1=Test1 & "my"
Test1=Test1 & "name"
[code]....
I believe there are nine Strings in memory at line ten as String is an immutable object, but only one reference to the String Test1 that contains: "Hello my name is Joe Blogs what is yours?". My question is; are all of these Strings picked up by the garbage collector when they go out of scope? i.e. when the sub routine finishes running. I seem to have a memory leak and am thinking that I should really be using a StringBuilder object.

Is there a way to use [string].Join to concatenate html stings including spaces? I want to join html strings with a special character so I can pass them as an array to javascript from the code behind.
Dim Array(100)

ArrayString = [String].Join(",", Array)
This works great if each item in Array is one word only, but what if each item in Array contains spaces?
I am using the contains method to look through an array to find matches, however I notice that when I use it it is case sensitive. Is there another method I can use to do a case insensitive search or some way to modify the contains method to search case insensitively? [code]
View 3 RepliesI was debugging one of the applications I work on and came across an interesting issue. For those unfamiliar with VB.NET, variable names are case insensitive. Therefore,
Dim foo As Integer
FOO = 5
System.Console.WriteLine(foO)
[Code]....
Variable names in VB.NET are typically case insensitive. The GetProperty method on Type seems to be case sensitive when it comes to the property name. Is there a way to call this method "VB.NET style" and ignore case? Or am I SOL here and need to apply a C# mentality and worry about casing?
am using VB.NET 2008 and am a complete beginner. am writing a programme that requires the user to select a number from a NumericUpDown control and the number selected will enable the equivalent number of GroupBoxes on a form following a click event.

think that the argument to be passed to the method or sub will be the Case condition but how do I return the corresponding code to enable the GroupBoxes? I have the same issue with resetting all my textboxes to some default text then the user activates more then one event.
I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.

I have an app that deals with currency. For display purposes I use the nifty VB FormatCurrency function which will format based on the OS's region setting. So, if in France you might get 123,45 where in the US you would get 123.45. To perform calculation on these amounts I use CDec() to convert to decimal.
My problem is that when I convert the Decimal to a String using toString() it formats according to the currently set region. I need to be able to always convert the decimal into a String representation for the US, i.e. with decimal points. I thought I would be able to do something similar to this:
.toString("#0.00")
