• An analog of String.Join(string, string[]) for IEnumerable<T>

  - by abatishchev

  class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

• How do I call functions of an object inside the same object?

  - by Roly

  I have the following Javascript code add_num = { f: function(html, num) { alert(this.page); }, page : function() { return parseInt(this.gup('page')); }, gup : function(name) { name = name.replace(/[\[]/,'\\\[').replace(/[\]]/,'\\\]'); var regex = new RegExp('[\\?&]'+name+'=([^&#]*)'); var results = regex.exec(window.location.href); if(results == null) return ''; else return results[1]; } } But when I call add_num.f() what I get from alert() is the actual code of page. That is, it returns function() { return parseInt(this.gup('page')); } I was expecting a numeric value and not any code at all.

• Post/Redirect/Get Pattern and Sticky Forms

  - by Scott Christopherson

  I'm using the Post/Redirect/Get pattern on a form of mine. I've never used this approach before and I'm trying to figure something out: Normally, I always just displayed the posted form again when there were validation errors and displayed POST values in the form (sticky form). However with the PRG pattern, the form is displayed after a redirect, so there aren't any POST values. So my question is, how can I implement the PRG pattern and still have sticky forms?

• Hibernate proxy serialization and receive on client side.

  - by Bubba88

  I lack understanding of how does the generated proxy class object (CGLib enhanced POJO) is transferred to the remote client and still pertains its ability to generate Lazy Init. Exceptions. Does that mean that there is some kind of contract that all the transferred objects of some kind of class (a proxy) will be reinstantiated as proxies again? Where does the client obtain those generated classes? Sorry, but I totally do not understand.

• TAPI lineGetAddressID() fails with LINEERR_INVALADDRESS

  - by PaulH

  I have a windows mobile 6 application using TAPI 2.0. lineGetAddressID() is needed to get the address identifier used by several calls in the telephone api, but I can't get it to work. I have tried the following to no avail: HLINE line; // valid handle from lineOpen(); DWORD addr_id = 0; result = ::lineGetAddressID( line, &addr_id, LINEADDRESSMODE_DIALABLEADDR, L"1234", 5 ); result = ::lineGetAddressID( line, &addr_id, LINEADDRESSMODE_DIALABLEADDR, L"5551234", 8 ); result = ::lineGetAddressID( line, &addr_id, LINEADDRESSMODE_DIALABLEADDR, L"1115551234", 11 ); result = ::lineGetAddressID( line, &addr_id, LINEADDRESSMODE_DIALABLEADDR, L"11115551234", 12 ); All of them return LINEERR_INVALADDRESS. Can anybody point out what I may be doing wrong? As a side question, how can I programmaticly get the address? It appears in the LINEADDRESSCAPS structure returned by lineGetAddressCaps(), but that requires an address identifier (which would need to come from lineGetAddressID(), which requires an address...). Note: I realize I could use 0 as the address ID and it will probably work, but I have no guarantee it will work for every platform. I would like to get this solved 'right'. Thanks, PaulH

• Datetime NOW PHP mysql (+ PDO variant)

  - by Chris

  Thanks for looking. All helpful answers/comments are up voted. In php, you can use NOW() like this: mysql_query("INSERT INTO tablename (id, value, time_created) VALUES ('{$id}', '{$value}', NOW())"); How can I do the same thing in PDO. When I bind like this, I get an error: $stmt->bindParam(':time_added', NOW(), PDO::PARAM_STR); Is it the PDO:PARAM_STR?

• Why would latency suddenly go up when crossing networks?

  - by geoffreyf67

  I'm looking at the latency from my machine to a world of warcraft server. Every hop while I am in Comcast's network is sub 15ms. Then it hits ATT and goes to 60-70MS for the rest. Why would it suddenly jump from 15 to 60 considering it's still in the same city? Is there anything I can do about it? G-Man

• Vibrations when exploding/repacking movie

  - by Stefano Borini

  Please bear with me, I know that what I'm doing can sound strange, but I can guarantee there's a very good reason for that. I took a movie with my camera, as avi. I imported the movie into iMovie and then exploded the single frames as PNG. Then I repacked these frames into mov using the following code movie, error = QTMovie.alloc().initToWritableFile_error_(out_path, None) mt = QTMakeTime(v, scale) attrib = {QTAddImageCodecType: "jpeg"} for path in png_paths: image = NSImage.alloc().initWithContentsOfFile_(path) movie.addImage_forDuration_withAttributes_(image, mt, attrib) movie.updateMovieFile() The resulting mov works, but it looks like the frames are "nervous" and shaky when compared to the original avi, which appears smoother. The size of the two files is approximately the same, and both the export and repacking occurred at 30 fps. The pics also appear to be aligned, so it's not due to accidental shift of the frames. My question is: by knowing the file formats and the process I performed, what is the probable cause of such result ? How can I fix it ?

• Is there a redraw-event for HTML5's canvas element?

  - by valmar

  As the title says, I need a notification when the content of a canvas element was redrawn. Is this possible? If not, a notification when the whole page was redrawn would also be ok (reDRAWN not reLOADED!). The reason why I need this is that I want to get the current FPS of an animation running inside a canvas.
