I tried to open test.csv with excell and it is opened just fine. but when I tried to save it again, it seems like excell didn't recognize it as a valid .csv file. it will show save as type as a unicode text (*.txt) file instead of a *.csv file.

VS 2008 Save String As .txt File?
Dec 30, 2009I want to make a program where lets say I have a text box and a button. Every time you click the button, it saves the text in the textbox to text.txt in C:. How would I go about doing that? I have done a tutorial on how to create a word editor where it asks you what and where you want to save the file, but what if I just want it in the same place every time and want it to write all of that text to a text document?
View 11 Replies.net - Assign Value To String?
Apr 29, 2012Consider following code:
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()

Dim S1 As String = "a"
Dim StringFromFile As String = "S1=hello"

Assign Empty String To Property With Value Of Nothing
Jan 5, 2011In 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.
Assign Variable By Name Indirectly As String
Feb 16, 2011Any 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.
C# - Pass In A Property Name As A String And Assign A Value To It?
Aug 9, 2010I'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?

Combo Box Selected Item Is Null - Assign An Empty String To It Instead?
Dec 9, 2011I have a property called ReplacementTo and I set a value to it based on the selecteditem from the combobox, like this:
classEquipmentItem.ReplacementTo = cmbReplcmnt.SelectedItem.ToString
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?
