Convert String Variable to an Integer?
I tried this[code]...
I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).
Ive got a few strings stored inside a string array, and i need to copy each string element into the integer variable on each iteration.how i would convert it? tried
CInt(stringArr(lc))
but got errors?
Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]
View 2 RepliesI'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
View 3 RepliesSay that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

I am developing an app which allows a user to send emails.I am using a multiline text box for the user to capture data, but when I convert it to a string it does not pick up a new paragraph.How would I insert a <br> & </br> for a new line within a string variable?
View 6 RepliesTo be honest I am fairly new at VB as a language, and I just came across a problem that I can't figure out. I have a feeling it's something simple...but here it goes.I created a set of string variable on my first form as follows:
Dim strpro1 As String = txtpro1.Text
Dim strpro2 As String = txtpro2.Text
Dim strpro3 As String = txtpro3.Text
Dim strpro4 As String = txtpro4.Text
Dim strpro5 As String = txtpro5.Text
I set strpro1 as a global variable in my module:Module Module1 Public strpro1
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?

I'm trying to make a program that can export my schedule into a CSV file to upload on to google calender.I need to extract some text within a textbox control. I'll show you an example.This is the text in the textbox:
Quote:
Monday, 10 January, 2011
09:45 - 18:00
Phone Work09:45 - 12:15
[code]....
I need to get just the date and times from this list, and put them in variables. so that I'll end up with:
1) A string with a value as a date, which would be "10 January, 2011" for example: strDate1 would have the value of "10 January, 2011"
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

I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.

View 4 RepliesIs it possible to make a variable hold a reference to an integer instead of copying its value when using integerVariable = integerValue ?
View 2 RepliesI have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.
Is there a way of testing to see if a number variable is an integer, or a decimal?
View 8 RepliesI want to assign the value of the integer returned from the InStr method to a variable. So, If TextBox2.Text = "The Apple Pie" And TextBox1.Text = "App", I want the integer returned, which in this case would be 5, put into a variable, lets say its called 'VarString'.
So VarString (would) = 5.

I am a .net beginner trying to make a crossover from vb6. I am trying to copy bytes of integer to a variable but I am getting this error msg. PInvokeStackImbalance was detected
A call to PInvoke function 'Tutorial_Class Dog!WindowsApplication1.ModAPIFunc::CopyMemory' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature.

I know vb.net does not include pointers like C language. but I am trying do populate an simple integer array with variable of the same type for example :
dim variable1 as integer = -1
dim variable2 as integer = -1
dim intArray() as integer = {variable1,variable2}

it is a very simplyfied verson of what I want to do.I want to change the value of ma variables with my array referencing them with an index as if my variables were pointers of integer in c++ for example so that normally after the example, both variable should hold the number 3 instead of the number -1?
