I want to append string in front.
'For example
Dim value As String = "a"
'I want to append the 'value' string so that it prints the below:
' gfedcba
I found the below thread which tells the solution for my problem: [URL]
But I was wondering if there is way to achieve the same result using "&" instead of "+" ?

I had a textbox and I could append strings to it.But now I create a string like this:
Dim str As String = New String("")
And I want to append to it other strings. But there is no function for doing so. What am I doing wrong?
{"status":"OK","data":[{"service":"hotfile","sid":"alcva","filename":"Cash.2008.x264.utkuemre.part1.rar"},
I need to convert the string above into - bearing in mind the string is not constant [URL]
So in this example it would be [URL]
What is the code that will extract only these pieces of this information?

I am building an equation parser, it takes the equation
"( 3456 + 321 * X ) / 45"
For example. As I couldn't find a direct solution to parse this equation, I split the equation and started implementing the operations 1 by 1 until I stuck with the execution order of the arithmetic operators (as the multiplication should be performed before the addition). So I am trying now to avoid this and try to parse the full equation. Is there a way to convert the string "+" to + for example?

Given a string as a form of input (parsed from an input file) which represents a number and a mathematical operator (<, >, <=, >=, !, !=, and a few others), what is a really fastefficient way to chop off that operator, compare it to a list of valid operators, and then set an "operator" variable to a state (i.e., Enum) representing the identified operator, then return just the number (as a string)?I'm open to various ideas and implementations.I've tried several (about 6-7) myself, and find I'm not really satisfied with the speedThe fastest so far is a For Each loop that walks my list of "valid operators", and compares that operator's string representation against the chopped off bit from the numeric string. I determine the amount to chop off by the length of each valid operator in the valid list.
Here's a code example of the fastest implementation. Assume input like <378 and a valid ops list of <, >, !, or >=79 and a valid ops list of <=, >=:

View 4 RepliesI am writing a library in VB.NET in which I have added, among others, a class originally written in C# but converted into VB.NET.

I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.
I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...

I have the following query
Dim get_rmf_2 = From rmf In t_rmf _
Where rmf!NIVP = nivp_rap
When i run it i get an error :
Operator '=' is not defined for type 'DBNull' and string "test".
I suspect this is because the column "NIVP" in the datatable contains null values, I've tried yhe same thing without null values and it works.So how can i make this work ? ; the column "NIVP" really has a row "test" , and a normal SQL query works fine.
