Dim S1 As String = "a"
'this is the string in a file
Dim StringFromFile As String = "S1=hello"
[code]....
how to assign value to S1?I have declared a string named S1. Now I want to assign new value to S1. The new string value is stored in a file using following format: [variable name][= as separator][string value]. How do I assign the value to S1 after retrieving the string variable name and value that stored in a file?
NOTE:
temp(0) = "S1"
temp(1) = "hello"
It should be noted that the string with the data comes from a file that may change from time to time! When the file changes, I want the variables to change as well.
Further clarification I need a piece of code that when processing a string like this "S1=hello", the code will first find a declared variable (i.e. S1), and then assign the S1 variable with "hello" string. The "=" just acted as separator for variable name and variable value.
UPDATE:
My attempt to use Mathias Lykkegaard Lorenzen's EDIT 2 example but failed with "NullReferenceException" on this line "Field.SetValue(Me, VariableValue)". Please help me fix the problem. Following is my code based on Mathias Lykkegaard Lorenzen's EDIT 2 example:
Public Sub Ask()
Try
Dim S1 As String = "a"
Dim StringFromFile As String = "S1=hello"
Dim code As String code= " <meta http-equiv="Content-Type" content="text/html; charset=windows-1254"> "
i think i am getting this error because of double Quotation marks "character constant must contain exactly one character."how can i assign it to a string?
In my EF4 EntityModel I have an entity named Users. Users have the common UserName and Password string fields. If I do something like this
Dim u as new USERS U.UserName = String.Empty Then U.UserName are still Nothing.
But if I Do Something like this Dim u as new USERS u.UserName = "A" u.UserName = String.Empty Then U.UserName take String.Empty as value without problem.
The reason is the way that EF4 generate the UserName Property Public Property UserName() As Global.System.String Get Return _UserName End Get [Code] .....
I do not want to make two assignations every time I want to set string.empty to a property with a nothing value, and I do not want to remember that I must do it in this way everytime, because I'm pretty sure that I will forget it and then I will introduce bugs in the code. I just want to assign the empty.string value to a property and the property take "" as value.
Any way to attempt to assign a variable within a data class or structure when I have the variable name as a string. Where would this be useful? Let's say I have a data class that exactly mirrors the columns of a table in a SQL database. This lets programmers easily interact with table row data as it gets passed around as an actual, specific object since Intellisense can enumerate the variables for them, etc.
However, populating such an object is tedious and repetitive--the programmer who creates the new object has to one by one match up all the members when reading from the SQL data adapter. It would be nice if they could somehow enumerate all the variables in that class and attempt to auto-assign the values from the database instead of having to build a custom population method for each new data class. A person could create a hash table or tree or something that pairs member names with actual objects.
I'm setting up a simple helper class to hold some data from a file I'm parsing. The names of the properties match the names of values that I expect to find in the file. I'd like to add a method called AddPropertyValue to my class so that I can assign a value to a property without explicitly calling it by name.The method would look like this:
//C# public void AddPropertyValue(string propertyName, string propertyValue) { //code to assign the property value based on propertyName } 'VB.NET'
[Code]...
Is this possible without having to test for each individual property name against the supplied propertyName?
I want to be able to read in/assign a string but not have any of its characters within delimit anything....For example, how the ' "" ' is used to represent one ' " '
Now I can't use cmbReplcmnt.Text because what I actually need is the value of that SelectedItem
So problem is, if the user leaves the combobox as blank, it throws a null exception.I decided to use the IIf function then:classEquipmentItem.ReplacementTo = IIf(IsNothing(cmbReplcmnt.SelectedItem.ToString), classEquipmentItem.ReplacementTo = "", cmbReplcmnt.SelectedItem.ToString)
Unfortunately I still get the error I tried using a Try-Catch for it and it worked, but I don't want to rely on the Try-Catch, so I was wondering is there a another way to work this through?
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?

Does Visual Basic arrays have the possibility to assign values in one line?i.e. No need to have a loop to assign a value for the whole array.for example,
Dim Array1 (1000) As Integer = 478 Dim Array2 (1000, 1000) As Integer = 852
this means that all values of array1 will be 478 and the other is 852.
I have a label, lblmessage, which I want to assign 4 different values. It should show up like this:
[Code]...
I know this: lblmessage.text = "5" and to assign it another value lblmessage.text = lblmessage.text + "4". This just puts them next to each other, but how can I get them to show up underneath each other?

I've been making this BlackJack program for a school project
I have 52 image files, labelled from '_1' to '_52' in my resources folder, each number corresponds to a card.
My question is, how do I get a picture box to assign the correct resource according to a variable
So, say I have
"pictDealerCard1" -> picture box which displays the first of the dealers card DealerCard1 = 37 -> random number generated through INT(RND() * 52) and resource '_37'

I have an application in VB.Net that displays the results of a math operation to a listbox. For example I have the 12345 + 12345 = 24690. What I'm trying to do is to have the first 2 numbers (12345 and 12345) copied to 2 different textboxes when listbox item is selected. Here's the code I have so far:
'Make sure that we have a selected item before continuing If listBox1.SelectedIndex = -1 Then Return
[Code]....
During runtime it only works with index 1 when it gets selected. I have 10 records being displayed (0 to 9). None of other indexes are being shown at the textboxes.
I am experiencing aproblem in my VB.NET App. The salary form is a databound form in my app to a linq data source. There are several text boxes to enter and calculate different salary fields. e.g. Basic Salary, Budgetary Allowance and Adjusted Basic Salary...
all the above three controls are bound to the datasource. now on the Leave events of the Basic Salary and Budgetary Allowance there is a function to calculate Adjusted basic salary.
The problem is i dont see the calculated amount in the adjusted basic salary but i see only the underlying data in the database instead of the programmatically calculated amount.
