I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.

View 7 RepliesI'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:
CreateString += TextBox1.Text + TextBox2.Text + TextBox3.Text... (etc)
I have thought about creating a For Next loop which would go something like:
For i As Integer = 0 To intNoTextBoxes
CreateString += TextBox(i).Text
Next
But this really doesn't work. I also found something saying that something similar to this would work:
For i As Integer = 0 To intNoTextBoxes
CreateString += Me.Controls.Item("TextBox" & i.ToString).Text
Next
But that didn't work either.

How do I convert from a string to an integer? Here's what I tried:
Price = CInt(Int(txtPrice.Text))
I took out the Int and I still got an exception.
I know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....
Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:
Select Case (nRecordType)
Case "01"
...
Case "02"[code].....
Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.
Edit 2:This is what I've done now and I think it should work:
Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....
I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.

I am working on a form of copy protection for some software i am developing. In order to generate a unique license for a machine i am aquiring information about the hardware the software is running on. For this task i aquire the 'BIOS version' of the machine using the Win32 libaries. As the BIOS version format can vary from machine to machine i need to be able to convert a string value to a integer so i can perform a mathmatical calculation on it.
A typical BIOS version output may look like 'GBT42302e31' for eg once all the spaces and characters are removed. However this output can change dramatically between motherboard manufacturers.How do i convert the value 'GBT42302e31' to a integer like '5356243' for eg so i can then perform a calculation or hexidecimal conversion on it?.
I have tried the following and they all fail with numerous conversion errors:Cint Convert.ToInt64()
I want to take each character in a string and multiply it by 7 then 3 then 1. And then loop back to 7 etc. This is what I got but it doesn't work
For Each ch As Char In row("SCAN2").ToString
product = Convert.ToInt64(ch) * 7
Next
Lets say the first character is 8. It should be 8 * 7 = 56
but I get 392.
