How to make Cocoa document package type with it's extension hidden by default? -


I am creating a cacao application which uses a document package (bundle) because I have specified an extension And the searcher now recognizes the document as a document with extensions. But the extension of the folder is still displayed, and I want to hide it by default (like the application bundle) is there an alternative to doing this?

you -setAttributes: ofItemAtPath: error: the method of NSFileManager can set the file attributes of any file. In this situation, you want to set the value of the NSFileExtensionHidden key.

To apply this to your saved document, you can cancel the -writeToURL: ofType: error: in your NSDcast subclass and more Then set the file extension to hide after the document is saved: 

  - writeToURL: (NSURL *) absoluteURL ofType: (NSString *) typeName error: (NSError **) Out Error {// to save the call file if (! [Super writeToURL: absoluteURL type: typeName error: outError]) do not return; // Get the path of the saved file NSString * filePath = [absoluteURL path]; // File extension hidden attribute in the name of the NSDictionary * fileAttrs = [Object with NSDictionary Dictionary: [NSNumber Number Vithubles: Yes] for: NSFileExtensionHard]; If (! [NSFileManager default manager] setAttributes: fileAttrs ofItemAtPath: filePath error: outError]) {return; } Yes return; }

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...
