How do I check if a Unicode directory exists on Windows in Perl? -


I have to check whether a Unicode directory exists in Perl or not. I am using Windows XP and Perl Camelbox 5.10.0.

If I try to create a directory (such as Sinn has suggested here), which is already present, the program ends.

Unfortunately if (! -d $ dir_name) {# directory build $ dir_name} does not recognize the Unicode directory or I'm doing something completely stupid, I checked it Before trying to encode the name of the directory, but the result is the same.

How do I check for the existence of a Unicode directory?

While answering your first question, I forgot that it provides a decent interface I I will go and answer However, for your immediate problem, what you need to do is do not automatically die when the CreateDirectory call fails, but to check if the error code is 0xb7 ( ERROR_ALREADY_EXISTS ), then you go on your way to your delightful path. The problem is that it is difficult to go on your happiness.

When you have a Unicode file name, the solution is to use the solution Win32 :: GetANSIPath using the Perl function (just keep an eye on the full length of the path): 

  #! Use / usr / bin / perl strict; Use warnings; Use utf8; Use Encoded QW (encode); Use the file: Slurp; File :: spec :: functions use qw (catfile); Win32; Use Win32 :: API; Continuous ERROR_ALREADY_EXISTS = & gt; Use 0xb7; My $ dir_name = 'Wilgorad'; Unless (Win32 :: CreateDirectory ($ dir_name)) {my $ err = $ ^ E; If ($ err == ERROR_ALREADY_EXISTS) {Warning "directory exists, there is no problem \ n"; } And {die Win32 :: FormatMessage ($ ^ E); }} My $ ansi_path = Win32 :: GetANSIPathName ($ dir_name); Warning "$ ansi_path \ n";

Oh, and, good luck to delete that directory.

In a serious vein, however, the entire Windows Unicode file operation is a bit of a mess of things. / P>

As far as I understand these things, if you want to work with the path of the Unicode character to use the pell function like open , then you have to type the ANSI path Example: 

  My $ file = catfile ($ dir_name, 'test.txt'); Open my $ FH, '& gt;', $ file or die '' can not create $ file: $! ";

will fail 

  My $ file = catfile ($ ansi_path, 'test.txt'); Open my $ FH; 'gt; ; '$ File or die' 'can not create $ file: $! ";

will be successful (at least on my system) if you are going to use Win32 API functions to deal only with files (and your case may be easy) You do not need the ANSI path. There is a bunch of modules to assist you in later times.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
