• Drag and drop an image from desktop to a web text editor (implementation in javascript)

  - by fatmatto

  I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

• How to read in a negative double with scanf() in C

  - by rize

  I'm learning basics of C and writing a simple first order equation solver. I want the input to be exactly ax+b=c or ax-b=c, where a, b, c are double type. I'm employing scanf() to read in user input and to check if it's of the correct form. However, if I enter a negative double, -4.6 say, as the "a" in the equation, scanf() won't read the a,b,c correctly. I'm using %lf inside scanf(). How do I read a negative double, then? Many thanks. My code: if (scanf("%lfx+%lf=%lf", &a, &b, &c)) more code If I use as the input "-6.2x+3.4=-5.9", the value 3.4 will be assinged to variable a, while b and c remain as they were and "more code" is run.

• How to enable other languages for MailChimp List Subscribe Plugin?

  - by Lenin

  I have translated the MailChimp provided MailChimp List Subscribe Form plugin for wordpress. I used poEdit to edit. At wp-config.php I have language set as ar_SA. Which works for the themes I have used in two Bilingual sites. But the mo file had to be renamed to ar.mo I got two problems: While updating the catalog poEdit crashes. But I could save the .po and generated .mo successfully. The translated .mo doesn't appear for the confirmation success or error messages through the Ajax calls which its supposed to.

• Using now() in a <asp:textbox>

  - by Anthony

  Can anyone help. I am using a formview in VS 2005. I have different elements in my form databound to a database and I am performing an INSERT SQL statement. No problem. The problem is that I am trying to enter the current date into the SQL statement and I am having a problem. I can add <%now()% to the "Text" property of the asp:Textbox. But when I do, then I can't bind the textbox to a specific database column. How do I do both???? I can do this: <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("Initiate_Date") %>' ></asp:TextBox> Or this: <asp:TextBox ID="TextBox2" runat="server" Text='<%# now() %>' ></asp:TextBox> But I don't know how to do both.

• textbox disappears in paging - php

  - by fusion

  i'm calling the search.php page via ajax to search.html. the problem is, since i've implemented paging, the textbox with the search keyword from search.html 'disappears' when the user clicks the 'Next' button [because the page goes to search.php which has no textbox element] i'd like the textbox with the search keyword to be there, when the user goes through the records via paging. how'd i achieve this? search.html: <body> <form name="myform" class="wrapper"> <input type="text" name="q" onkeyup="showPage();" class="txt_search"/> <input type="button" name="button" onclick="showPage();" class="button"/> <p> <div id="txtHint"></div> <div id="page"></div> </form> </body> search.php [the relevant part]: $self = $_SERVER['PHP_SELF']; $limit = 5; //Number of results per page $numpages=ceil($totalrows/$limit); $query = $query."

• PHP Redirect one page to another server without showing URL

  - by gav

  Having just written the title for this question I am aware of how dodgy it sounds! I am writing a back end for storing volunteer information for some friends, they have their own website to which I can add a volunteer.php page. What I want is for that page to redirect to a page on my server showing the form for the users to fill in, I would prefer the ugly URL of my site not to show. Is there an easy way to do this? Load the page inside the remotely hosted page somehow? Thanks, Gav

• Help Writing Input Data to Database With Wordpress Plugin

• Why is passing a string literal into a char* arguament only sometimes a compiler error?

  - by Brian Postow

  I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0.

• Delphi for PHP - location of source

  - by Holgerwa

  I just installed Delphi for PHP to get an idea on how it works and have created a simple app with a button that puts a text into a listbox when it is clicked. The app works if I copy all required files to my webserver and run it from there. It also works if I save the project in the standard path: "c:\documents and settings\username\My Documents\Delphi for PHP Projects" But if I save the project in another directory, the ButtonClick event is not fired when the application runs from there. I've put a breakpoint in the event to see if it stops there but it doesn't. The OnShow event of the form works as usual. It really seems to be the path where the project is located to make it either work or not. As I said, I have no experience with Delphi for PHP so far, it is probably just a simple solution that I don't see...

• Displaying list of objects as single column in a bound gridview (Winforms)?

  - by Carrie Nelson

  I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification". In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer). So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column. So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?

• Aggregate functions in ANSI SQL

  - by morpheous

  I want to use multiple aggregate functions in a query. All the examples i have seem on aggregate functions however, are trivial. Typically, they are of the form: SELECT field1,agg_func1, agg_func2 GROUP BY SOME_COLUMNS HAVING agg_func1 OP SOME_SCALAR Where: OP: is a boolean operator (e.g. <, = etc) SOME_SCALAR: is a scalar (i.e. a constant number) What I want to know is if it is possible to write (IN ANSI SQL) queries like: SELECT field1,agg_func1, agg_func2, agg_func3 GROUP BY SOME_COLUMNS HAVING (agg_func1 OP1 agg_func2) OP2 (agg_func2 OP3 agg_func3) Where: OP[N] are boolean operators or ANSI SQL clause operators like 'BETWEEN', 'LIKE', 'IN' etc. Also, assuming this is possible (I have not seen any documentation saying otherwise) are there any efficiency/performance considerations (i.e. penalties) when the HAVING clause consists of a boolean expression combining the output of the aggregate functions - instead of the normal comparison of the output of the aggregate with a constant number (e.g. min('salary') 100 ) - which is often used in the most banal examples involving aggregate functions?

• Microsoft Office Access error

  - by CREFLY

  Hi All While I am running on MS Access myapplication.mdb, I am always getting this error "Microsoft Office Access Has encountered a problem and needs to close. We are sorry for the inconvenience, send error to report , don't send...". I tried to create a new application.mdb then to import the database, the form and the modules but I couldn't because I'm getting the same error while I'm importing most of the modules. P.S.: I'm trying to import the modules one by one but for the majority of the modules I encounter this error. I tried to open an old version of myapplication.mdb then to import the updated modules but just when I selected the damaged application to import the updated module I got this famous error directly... Any help will be highly appreciated...

• Convert String value format of YYYYMMDDHHMMSS to C# DateTime

  - by SARAVAN

  I have a need to convert a string value in the form "YYYYMMDDHHMMSS" to a DateTime. But not sure on how, may be a DateTime.Tryparse can be used to make this happen. Or is there any other way to do it. I can do this using some string operations to take "YYYYMMDD" alone, convert to a datetime and then add HH, MM, SS separately to that DateTime. But is there any DateTime.TryParse() methods that I can use in one line to convert a "YYYYMMDDHHMMSS" format string value to a DateTime value?

• How to programatically create and read WEP/EAP WiFi configurations in Android?

  - by Als

  How to programatically create and read WEP/EAP WiFi configurations in Android? I have seen a number of people struggling on this very question on various forums and all across the community. I know this is not that straight forward(especially EAP) to figure out because When I wanted to acheive the same I too struggled quite a lot.Well, all the hard work of code analysis and searching various implementations on the internet done with I was finally able to acheive the goal. All the credit goes to number of open source projects and their developers. I would like to share this knowledge with all, Since SO encourages this: "It's also perfectly fine to ask and answer your own question, as long as you pretend you're on Jeopardy: phrase it in the form of a question."

• Will Django user permissions work for models with inline tabular forms of other models?

  - by stinkypyper

  I am setting up DJango admin to make a model editable. On the same page I have tabular inline of a child model. Everything works as expected. Now I want to restrict permission on the tabular inline child form. Specifically remove update and delete permissions on it. I have tried removing the permissions for the admin user using the 'user permissions' of that user. However, it does not work. Does DJango respect the user permissions in regards to inline model forms?

• NET Framework Validation Library

  - by Kane

  As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

• Which Happens First? Anyone Know Exactly How The Apache Server Will Handle This Request?

  - by user310594

  Hello, To keep things simple, please allow the "assumption" that some code requires the use of a full URL, even though the domain is on the same server, i.e. a simple file path cannot be used. TCP/IP?? Question: If a form action target = "http://this-full-URL.com/postdata" (for example) and that URL is also on the same server, then which happens first? A) Data is sent "out onto the web", and then returns to the same server, or B) Before sending any (possibly sensitive) data, the server (Linux, Apache, PHP), first "discovers" the target address is local, so (clearly) no data is sent over the net? Thank you.

• How to change the text color of a QxtLabel

  - by dwj

  I'm checking out libqxt (an extension library for Qt) and cannot change the text color of a QxTLabel; it's driving me nuts. QxTLabel extends QFrame. QFrame doesn't know anything about text. I tried changing the palette via the Form Editor but that didn't appear to do anything either. I also tried to change the style sheet but, again, QFrame doesn't know about text and QxTLabel isn't giving anything up either. Nothing is jumping out at me from the full member list for QxTLabel either. Thoughts?

• dynamically updating a datagrid from a XML file c# 3.5

  - by Farstucker

  I have a datagrid that is populated via XML file when the form loads. Everything is working great but I would like the datagrid to update dynamically when a new order is received (Separate class receives a data stream and updates the file). Im looking for suggestions on how this should be done. (ie using a timer update every second, or monitor the file using FileSystemWatcher.. etc) Since where here, I might as well mention that in order to update the datagrid Im clearing the whole data set and Re-reading the file using: DataSet.Clear(); DataSet.ReadXml("file.xml"); dataGridView1.DataSource = DataSet; if this is not the proper approach, please offer any alternate suggestions.

• Function for averages of tuples in a dictionary

  - by Billy Mann

  I have a string, dictionary in the form: ('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0), "puppy's": (9.0, 1.0), 'head': (6.0, 1.0)}) Each parentheses is a tuple which corresponds to (score, standard deviation). I'm taking the average of just the first integer in each tuple. I've tried this: def score(string, d): for word in d: (score, std) = d[word] d[word]=float(score),float(std) if word in string: word = string.lower() number = len(string) return sum([v[0] for v in d.values()]) / float(len(d)) if len(string) == 0: return 0 When I run: print score('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0), "puppy's": (9.0, 1.0), 'head': (6.0, 1.0)}) I should get 5.5 but instead I'm getting 5.875. Can't figure out what in my function is not allowing me to get the correct answer.
