Oct 22, 2010

If i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g

## Convert Binary Numbers To Decimals

Jun 13, 2012

I've used .NET for a long time now but I have come across something I haven't had to do before and I'm struggling to work it out. What I need to do is work with binary numbers and convert them to decimals and vice versa but not necessarily using even numbers e.g. I would like to represent a number between 0 and 2047 which can be represented with 11 binary digits. Plus I want to represent a second number between 0 and 500000 which can be represented with 19 binary digits, and a third number, fourth etc. Then I want to string the whole binary results together and split it in to sections of lets say 5 bits each and convert those back to decimal.

row.Cells(1).Value = Format(row.Cells(1).Value, "{0:D0}") 'I've also tried using {0:C0}
row.Cells(1).Value = row.Cells(1).Value.ToString("\$#,#")

## German Windows Decimals - Reads Some Text From An Access Database?

Feb 14, 2011

I'm having problem with our germany customers whose operating system uses dot as thousand separator and comma as decimal point.I have an application which reads some text from an Access database, parse it into data and display on a datagridview,the program also needs to write the data into another file as input to another application. right now, it seems when my application parses doubles (say 0.2500),germany os will always return everything except the decimal dot(so 0.2500 becomes 2500),and that just messed up the whole process...so my question is, how can we detect the locale of the windows and parse the doubles correctly?

## VB 2010 Express - Remove Or Add Several References

Jan 21, 2011

I have taken my project that seemed to have several bugs in VB2008 Express and upgraded to 2010. I had to remove or add several references again. I don't have any more errors but I have the following 5 warnings that keep me from compiling the build. I was wondering if anyone could give me some suggestions on what these mean or how to take care of the problem. I will list the warnings below. I'm on a Win XP machine with Office 2010 (if that might affect things).

## VS 2010 - Any Way To Remove Illegal XML Characters

Feb 15, 2012

I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the

system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.

temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)

## VS 2010 - Cannot Remove Components With Uninstall

Jul 15, 2010

I don't know what's got into them but they decided to purchase vs2010 pro licenses in my company. Anyway i gave it a quick look and since i don't need to have it installed right now (service pack 1 first, Microsoft anti-bug law) i uninstalled it. The problem i see is that it leaves leftovers everywhere.C++ redist, ado components, sql r2 components etc. These will not be deleted if i just remove vs2010 but will be installed if i install vs2010 full.Anyway i ended up removing them one by one and it took about 30-45 minutes. So has anyone have done a removal? Is this the case? I cannot remove most of the components with one big uninstall?
