How To Truncate An Array

Sep 3, 2009

is there a simple way to truncate an array ? Something like placing an end characted in the array which would signify its end ?

Basically I have two arrays of slightly different sizes and I want to shorten them so they both have the same size. The end data I am truncating I don't need.

Truncate String Value To 17 Characters Only?

May 19, 2010

how to truncate my string value to 17 characters only.

in my program, the acceptable number of characters for First Name is 17. Characters more than 17 should be truncated but it may cut words in the middle. I need to make the length max 17 characters, but, if it cuts a word, it should also remove this half-word completely.

Truncate The Beginning Of A Log File In .NET?

Feb 24, 2010

I have an VB.NET app that writes the status to a log file in text format. Over time, the file is getting large and I wanted to know if there is an efficient way to truncate the beginning of the file.

To make things easier, I am looking to specify a file size (say 2-3 mb) and I am writing the log using a StreamWriter:

Using strm As New IO.StreamWriter(filelocation.log, True)
strm.WriteLine("msg to write")
strm.Close()
End Using

I thought about using the strm.BaseStream.Length to determine how much of the file to cut off, but by using the .SetLength it would cut from the end - not the desired result.

VS 2008 : Don't Use Int() To Truncate Numbers

Oct 4, 2009

I've been using it and even saw a method in a MSDN search given that suggests that it should be used but have found that there are defects using it. An example of problem occurring.

Dim db As Double
db = Int(10.12 * 100) / 100

db should be equal to 10.12 but the result you get will be 10.11. In the above example nothing is being truncated. If you added some digits right of the 2 it would give a good result. But if you're using a variable and it sometimes is equal to 10.12 or 9.12 etc. then a problem would occur. Also if 10.12 was replaced with 10.03 you'd get a result of 10.02. 10.04 gives a result of 10.03. 10.2 gives a result of 10.19. I'm now using code such as what is seen below instead of using Int() :

bd = Decimal.Truncate(CDec(10.12 * 100)) / 100

You could declare bd as a Decimal and then you wouldn't have to use CDec(). If I try Int(1012) the result is 1012 but Int(10.12 * 100) will give 1011. Pretty weird in my opinion.

Loop Does Not Truncate Into A Two Decimal Place Holder

Feb 14, 2012

I wrote a loop that posted an accrued principal cycle to a listbox for a period of 10 years (10 loop cycles). The problem is: not only does the amount of the principal reconfigure for each loop cycle, but it does not truncate into a two decimal place holder as it should. I would like to use the ("F2") but I am not sure where to put it within the code. Here is what I have for the Calculate button event handler.

VS 2010 Truncate Charachters HEX Data Stream (Serial)?

Instead it will put the the whole steam in the textbox and it will be in decimal format, not hex.

Implement WCF In VB?

Apr 5, 2012

We have a vb.net application where we have implemented multithreading. We determined that we need to either implement .net remoting or WCF. After researching remoting in .NET on MSDN, Microsoft considers remoting legacy for .NET framework 4.0 and recommends using WCF instead. My question is: can we implement WCF functionality into our VB.NET application or do we need to rewrite the app from the ground up in WCF?

C# - How To Implement Tracing In .net

Aug 7, 2009

I am implementing a tracing mechanism myself. Now what I'd like to know is what is the best way to implement this mechanism(I mean, the architecture).[code]But then I saw there is an TraceListener class that let's me implement Write and WriteLine methods. The big drawback is that both those methods allow only strings as arguments, and I'd want to be able to send a lot more info than strings. What should I do? Maybe my first ideia is the best?I do know there are a lot of tracing mechanisms like PostSharp and so, I'm just doing this for learning purposes!
