VS 2005 Converting A String Value To A Number?
Aug 11, 2009
[URL]..From the above link,i studied about the conversion.But i have a confusion:Whats the difference between the following two?CInt(myString) VB Only. This function converts the expression to an integer. A run-time exception is generated if the conversion fails.
Convert.ToInt32(myString) This function converts the expression to an integer. A run-time exception is generated if the conversion fails.
When should i use the first one and when to use the second one?

I'm having trouble getting information from a webpage. I've managed to collect a specific string from the webpage, and I want to convert it into a number, but the problem is, is the number is into the thousands, and it can't convert right normally. How could I convert the string, to a number, minus the comma(s)?

I'm converting some php code that tries to get a string to a length that is divisible by a certain number, say 10. To do so it appends "�" to the string to make up for the difference. In other words, it does something like:
dim difference as integer = 10 - (str.Length Mod 10)
for i as integer = 1 to difference
str += "�"
next
But the problem for me is that "�", which is the ascii code for the null character, is two strings and I don't believe that when VB loops over resultant string it will view that as one character. what could I append the string with to retain the expected behavior?

I understand the concept of bytes and declaring variables to save on processing space. I understand that the max value that can be stored in a byte is 255. I cannot seem to wrap my head around my current issue. I don't have much experience working with byte manipulation.

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
I haven't got the code, however I got the physical part of the program done with a label called Numeric Number and another called Roman Numeral, with text boxs next to each label. I also have a button called "convert" so when you enter a numeric number in, it'll convert it to a roman numeral. I need it to only convert from 1 to 10, but not accept a number less than 1 or more than 10.

Anyone know how to do it...?Below is the coding I'd done, but I don't know how to do the increment part. Anyone know what coding I need to add?

I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]

I was directed to update an old VB6 dll to VB .net as we are moving away from COM objects. The dll contains one function that does a bunch of high math calculations. I opened up a new class project in VS 2005, Imported System.Math, and then basically copied the function code from the VB6 project into the new class. When compiling, I made the assemble COM-Visible and also checked the Register for COM Interop in the project properties. I then copied the dll and tlb files to Windows/system32 and tried to register using Regasm.exe.
Even though I'm using the correct version for .Net 2, I still get error RegAsm : error RA0000 : Failed to load 'C:WINDOWSsystem32eagetairmiles.dll' because it is not a valid .NET assembly. When attempting to add a reference to it in my new .Net project, I see it in the COM tab - but in the location it was developed in, and I receive the following error: Converting the type library to a .Net assembly failed. Type library mydllname was exported from a CLR assembly and cannot be re-imported as a CLR assembly.

I'm having an issue with my base conversion program. It seems to have a problem converting from base36 to base10 properly. After debugging all night, I've found that it's one certain function that's not working properly. The function seems to convert every last test number correctly, until I start getting into 11-digit numbers in base36. I have the max digits allowable for base36 set to 12 (so as not to exceed the base10 18-quintillion or so that an unsigned long can hold). I'm starting to think the issue is with VB and not with my code.The function as I've written it is below (DIGITS is a global const string ="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ", and itr is a global integer used throughout the code for iteration):
'-----------------
Public Function FromBase10(ByVal iValue As ULong, ByVal cBase As ULong) As String
Dim remaining As ULong = iValue

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
