Re: C# how to keep datetimes independent of regional settings

As Davey says, DateTime.Now just returns a time - it has no format. When you specify the output format, then you can use the current culture, specify a culture, or fix the format so that it is culture invariant.
Have a look here[^] - it shows all the various parts you can use to format your date.

As others have pointed out, a DateTime is a region independent structure already. What you are talking about is using a format converter to control how it is displayed.

Before you look at setting the output of the date to be a particular format, I must ask you to consider how your application is going to be used; people have a specific local regional setting in place and generally expect their dates to be displayed in those formats - this can be critical because it has an effect on the understanding of the date. When I looked at your example, my first thought was that you were talking about the 6th of May because I am based in the UK, by displaying a different regional setting you have skewed my understanding of your data.

Ah, DateTime, a perfect source of confusion around the globe. You might want to read this[^]. It holds some cues, including a reference to the infamous ISO 8601.

Thank you for your response. I have found out the solution .
I am setting my Application Culture at startup

handle of parent window containing windowless content

I want to find the handle of parent window containing windowless content. Example of web page containing windowless content is http://www.metacafe.com. On this site video files is getting played in windowless mode i.e. the player is not a window but just an content embedded in some other window (host/parent window). I want to determine handle of this parent window. contrary to this on youtube, the area on which video runs, is in itself a window.

Using spy++, I can determine the hierarchy of window in the IE window and If i will follow this hierarchy I can reach to the host/parent window on metacafe. But I believe it would only be applicable to metacafe. There must be some site which will host windowless content in different windows hierarchy.

So, please let me know if anyone knows how to get window handle of parent/host window containing/hosting windowless content.

hi,
I have a big problem in building deffrent mode of my application, imagine that we have a project contans of 3 part, for example a,b,c.In part a some codes of b and c must not be compiled in compile time, for this i used #define preproc and now, i need to compile full project by defining a, b or c
there is a command which is csc.exe /define:[a|b|c]
but this command only compiles one file and make exe. Now is there any way to compile a project with defining ? of course not changing source codes!my project considers 1000 source files D'Oh! | :doh:

Don't post the same question in the forums and QA - it duplicates work and annoys people.

You should take a closer look on MSBuild!

You can execute the following command to use your specific #define variable.
For example:

msbuild /t:Rebuild /p:Configuration=Release /p:DefineConstants=YourDefineStatement YourSolution.sln

This will rebuild the specified solution. It will result in a release build with the YourDefineStatement specified as preprocessor define statement.

No, you can compile multiple files or produce a DLL. CSC is called by Visual Studio, so it can compile and produce anything VS can.

How to write this regex?

I know nothing about regex. I want to replace some charaters in a string.They are:

+  -->   {+}
^  -->   {^}
%  -->   {%}
{  -->   {{}
}  -->   {}}

Who can give me the C# code? Thanks in advance.

Why do you have to use a regex? If you're not comfortable writing them and you don't have a complex pattern to parse, then don't bother. You can always use string.Replace instead which would do the job equally well. A lot of times, people are advised to use regular expressions when they don't add value, and it really is a case of using a sledgehammer to crack a nut.

Sometimes though, a regex is the right thing to use. String.Replace in this case is really nasty, partly because there are six cases, but mostly because two of the cases are included in the output of all six... Big Grin | :-D

Perhaps something like this:

string inputText = "+{}^%";

// This is the search string
Regex regex = new Regex("[\\%\\{\\}\\^\\+]",RegexOptions.Compiled);

// This is the replacement string
string regexReplace = "{$&}";

// Replace the matched text in the InputText using the replacement pattern
string result = regex.Replace(inputText,regexReplace);

I tried. But... Laugh | :laugh:

I inputed:

\begin{equation}
y&=x+z;
m&=[s]^2%4
\end{equation}

The result was:

{+}{{}{}}{^}{%}
