View 10 RepliesI'm looking for visual basic.net code (for visual basic express) to take automatic screenshots (timeout=60 seconds) for application testing. But every code has a lot of bugs:For example: [URL]Errors like:
Error 1 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.
Error 2 'Private Sub InitializeComponent()' has multiple definitions with identical signatures.
Error 3 'components' is already declared as 'Private components As System.ComponentModel.IContainer' in this class.
I 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 don't know much about C# so therefore I have used online C# to VB.NET-converters. Now I am stuck with some code which I believe the online-converter was not able to "translate" properly.
When running the code I get the following error:
System.IndexOutOfRangeException was unhandled
Message="IndexOutOfRangeException"
StackTrace:
at System.String.get_Chars()
[Code]...
a simple question. Given the following code:
Public Class MyClass
Private WithEvents pPerClass As PersistableClass
Public Overridable Property PerClass() As PersistableClass
Get
Return pPerClass
[Code]...
the first being a duplication of the second key, strangely obtained from a private field.
If you remove the WithEvents keyword, the pPerClass_PersistableClassID key is not created.
I am new to EF but it seems to me a strange behaviour.

View 5 RepliesWhat i'm trying to do is compute whether an integer number is prime or not. The program performs this analysis for all odd numbers from 3 up to an input integer limit, for example 100. If the integer in the range 3 to limit is prime, a message stating so is printed. Otherwise, a message is printed that lists at least one other integer divisor. The output for each analyzed number consumes one line of text.
A sample output is shown below:
Limit is 100:
Number 3: is prime
Number 5: is prime
Number 7: is prime
[CODE]...
I understand I need to use loops, boolean functions, vbmath(), strings and multi-line out via concatenation. So I can put this is words how I think it should be done but not so great putting the code together
Test all integers up to the SQRT of the number (100)
limit = math.sqrt(100) + 1
Followed by 1 For statement
For c = 0 to 100 step 2?
And an If statement
If ......
result = false
this function enables you to calculate a full arithmetic calculation , as 5*(3+2)+6 , but : it's limited with (+,-,*,/) signs . is there any way to add a support for the another signs (like : !,sin,cos,tan,root,^,log and another signs) to give the user the ability to calculate a full calculation including the other signs which cannot be calculated within the compute.datatable function ?
