php - Which characters should I escape/sanitize for file names? -

-

I have to clear some data that will be used in file names. Some data contains empty space and ampersands character What is a function that should be used in a file name (or path) to save or secure the appropriate data? I did not find anyone in the PHP manual's 'Filesystem Function' section.

So, suppose I have to write my function, which characters do I need to escape (or change)?

If you have an opportunity to store the original name in the database, then I will create a file with just a random hash (mt_rand () / Md5 / SHA1). The advantage will be that you do not rely on the underlying OS (character / path length), value or length of user input, and additional file names can be estimated. Probably Base 64 encoding is also an option.

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view.

How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

java - django-like frameworks? -

-
Hi, I've been working with Django for a few months and it's really helpful i just like java or c # Is there a similar framework for other programming languages? The problem I have with Digengo is finding a server to host this project because support servers are more expensive and are hard to find. In Django, I find the following items useful: Object-Relational Mapper, Admin Interface URL Management. Thank you! Because of the hosting aspect, I suggest if you are looking for only one option That you are easily looking for suitable hosting, the way you like it. If you are looking for a good Django host, then I highly recommend it. If they are not your cup of tea, check out, which has a great list of good Django hosts.
