VS 2010 Number Base Conversion?

May 13, 2010

I have been using this code for a long time now and it has always been accurate. I recently tried to convert a large string from one base to another and some weird stuff happens.

When I convert from base 36 to base 10, the result is accurate. When I convert the result back to base 36, it becomes inaccurate.

Decimal To Alphanumeric Number Base Converter Library In Program?

Mar 16, 2012

I'm looking for a decimal to alphanumeric number base converter library in Visual Basic that does not use recursion. [url]...

which includes a demo app but discovered that it uses recursion. The problem with it using recursion became apparent when I attempted to integrate the library into my own Visual Studio Express 2010 Visual Basic project: I got a stack overflow exception.

Now I could consider increasing the size memory allocated for the stack but it might be hard to determine what this would be, given that the recursion depth might vary depending on the value to be converted.

VS 2008 Win 7 - Built With Several Functions?

May 14, 2010

i have an application that's in development, but some modules of the application are already built, so the application it's installed in several computers. In my code, i call an external class that i built with several functions that i use in multiple applications, in this class i have a small piece of code that checks in the network (internal), if a new version of the application (Msi File), of the current application it's available, and if it's available, it runs the Msi file.

msiexec /package MSIPackage.msi That worked fine in windows XP, but now some machines have been upgraded to windows 7, and the user need other credentials to run the package. (Elevate Privileges). Other problem it's that in my application i create several folders in the installation and the user doesn't get any permissions to write in the folders.For example i have one Log folder, and i can't write any logs to it.

Linq And SQL Metadata Built In Functions?

Jan 13, 2011

So I wanted to check when last a table was changed, and I basically came up with this query:

SELECT DB_name(database_id) as [Database],OBJECT_NAME(object_id ,database_id) AS DatabaseName, last_user_update
FROM sys.dm_db_index_usage_stats
where DB_name(database_id) = 'Database Name'

Now what I want to do is put this in my code using LINQ. I have added the view to my datacontext and all that good stuff, but I don't really know how to do the SQL built in functions DB_Name and OBJECT_Name. I realise that I could do some sort of join to get the values for the id's instead, but I don't know which views I can find the database name and object name in.

Is there a linq equivalent to these functions? Alternatively, what are the system tables/views I need to look at to convert these ID's into their respective names?

Base Class With Shared Fields And Functions Good Design ?

Apr 22, 2010

I've got a BaseDataClass with shared fields and functions

CODE:

I have several classes that derive from this base class. The derived classes have all Shared functions that can be called directly from the BLL with no instantiation. The functions in these derived classes call the base Init(), call their specific stored procs, call the base CleanAll() and then return the results.

So if I have 5 derived classes with 10 functions each, totaling 50 possible function calls, since they are all Shared, the CLR only calls one at a time, right? All calls are queued to wait until each Shared function completes.

Is there a better design with having Shared functions in your DAL and still have base class functions? Or since I have a base class, is it better to move towards instance methods within the DAL?

.net - Getting Base Field Type When Databinding To A Decimal (or Object) Property?

May 28, 2012

I've got a custom NumericEditor control that has a nullable Decimal property called Value. When I bind a data field to Value, I'd like to retrieve the underlying Type of the data that's bound, so that I can restrict the use of decimal places if the source field is an integral data type.I figure I'd have to do this in the BindingContextChanged event, but how do I get the Type of the data field from the binding itself? My Google-Fu is failing me at the moment.

In short, I'm looking for something like the GetValueType method mentioned in the following question: Simple databinding - How to handle bound field/property change. Winforms, .Net I imagine this method would also be handy if the Value property was an Object.

Decimal To Binary Conversion?

Mar 6, 2010

I write a program to convert Decimal numbers to Binary numbers. It is working well. But I want to control the bits. i.e - We can write 31 as a) 11111 or b) 011111. When I run my program it displays 11111. I want to take input bit from a text box and display it like 0011111 or 011111 or what ever bit I input. How can I do that ?

Private Sub DecToBin()
Dim i As Integer = txtDec.Text
Dim binary As String = Convert.ToString(i, 2)

Conversion To Integer, Decimal, Double

Jun 9, 2011

So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))

Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.

Double To Decimal Conversion Error

Feb 11, 2009

I am writing a program that asks the user for their name and the number of pieces they completed. The employees are paid more depending on the amount of pieces they have completed(i.e. <200 = .50 per piece, 200 to 399 = .55 per piece, etc.). I have to display the amount earned when the user enters the info and hits the calculate button. I have to use Select Case.

I was thinking this would be an easy program but I keep getting an error for each Case saying "Option Strict On disallows implicit conversions from 'Double' to 'Decimal'. I don't understand why it thinks it is a double. It says I can correct this problem by adding "Cdec" before each equation(i.e.
