• Convert Justified Paragraph To Image

  - by rsrobbins

  I need to convert a paragraph of text into an image. Converting the text into an image is no problem. I have the code to do that. But the text must be shown as a paragraph with each line centered. That is a problem! Currently I can convert the text into a left justified paragraph because there are carriage returns in the text string. I suppose it could be center justified with spaces in the string but it would be hard to calculate the required spaces. There must be an easier way. What I need is some way to format the text into a paragraph and then convert it back into a string, preserving spaces. This needs to be done in VB.NET for an ASP.NET web application. Any ideas? I could get the paragraph justified in Rich Text Format but I don't know if it can be converted back into a string, preserving spaces. Creating a PDF is another possibility. The image created from the text needs to be 300 DPI with a transparent background. I'm using the DrawString method of a Graphics object to create the image.

• How can I use a meter-style progress bar?

  - by Yadyn

  In Vista/7, the Windows Explorer shell window makes use of a special kind of static progress bar to display hard drive space. With default styles, this bar is blue colored and non-animated. It also turns red colored when it gets close to being full (low disk space). Using messaging, I can tell the Windows Forms ProgressBar control to update its state to Paused and Error (yellow and red colored, respectively), which works fine, but these are still specific to progress. In the Windows User Experience Guidelines, it specifically points out this "meter" variant of the Progress Bar: This pattern isn't a progress bar, but it is implemented using the progress bar control. Meters have a distinct look to differentiate them from true progress bars. They say it "is implemented using the progress bar control", so... how? What message could I send to the control to have it behave this way? I've seen that you can send messages for setting the bar color, but the documentation says these calls are ignored when visual styles are enabled. Nothing else in the Windows API documentation for raw ProgressBar controls seemed to suggest a way to do this. Am I just stuck making a custom drawn bar? I'd really like to utilize the OS whenever possible so that the application will appear consistent throughout different OS versions. I realize that pre-Vista versions probably won't support this, though. I'm looking for a Windows Forms solution, but I wonder if it is even exposed at all via Win32 API.

• Learning PHP - start out using a framework or no?

  - by Kevin Torrent

  I've noticed a lot of jobs in my area for PHP. I've never used PHP before, and figure if I can get more opportunities if I pick it up then it might be a good idea. The problem is that PHP without any framework is ugly and 99% of the time really bad code. All the tutorials and books I've seen are really lousy - it never shows any kind of good programming practice but always the quick and dirty kind of way of doing things. I'm afraid that trying to learn PHP this way will just imprint these bad practices in my head and make me waste time later trying to unlearn them. I've used C# in the past so I'm familiar with OOP and software design patterns and similar. Should I be trying to learn PHP by using one of the better known frameworks for it? I've looked at CakePHP, Symfony and the Zend Framework so far; Zend seems to be the most flexible without being too constraining like Cake and Symfony (although Symfony seemed less constraining than CakePHP which is trying too hard to be Ruby on Rails), but many tutorials for Zend I've seen assume you already know PHP and want to learn to use the framework. What would be my best opportunity for learning PHP, but learning GOOD PHP that uses real software engineering techniques instead of spaghetti code? It seems all the PHP books and resources either assume you are just using raw PHP and therefore showcase bade practices, or that you already know PHP and therefore don't even touch on parts of the language.

• iOS 7: Best way to implement an textview that presents previous input but is easy to clear

  - by Frank R.

  I'm porting a Mac app to the iPhone and I've run into an unexpected problem. On the Mac there's a text field that is automatically pre-selected (= first responder) when a dialog shows up. The text field shows the text you entered in the field the last time and the text is pre-selected so that if you just start typing it gets cleared away. If you want to edit the existing text instead you just hit the forwards or backwards arrow. On the iPhone this behavior seems very hard to implement. The text view shows up with the old text and I can even get it to pre-select but whatever I do the result is not quite right. When I use [aTextView setMarkedText: myText selectedRange: newRange]; the text does show up as marked and if I just start typing the old text goes away. However there's no equivalent to the cursor keys on iOS, so I cannot NOT erase the text.. which is hardly the point. What kind of iOS idiom would be appropriate for giving the option to either edit or overwrite existing text? Best regards, Frank

• PyGTK: Manually render an existing widget at a given Rectangle? (TextView in a custom CellRenderer)

  - by NicDumZ

  Hello! I am trying to draw a TextView into the cell of a TreeView. (Why? I would like to have custom tags on text, so they can be clickable and trigger different actions/popup menus depending on where user clicks). I have been trying to write a customized CellRenderer for this purpose, but so far I failed because I find it extremely difficult to find generic documentation on rendering design in gtk. More than an answer at the specific question (that might be hard/not doable, and I'm not expecting you to do everything for me), I am first looking for documentation on how a widget is rendered, to understand how one is supposed to implement a CellRenderer. Can you share any link that explains, either for gtk or for pygtk, the rendering mechanism? More specifically: size allocation mechanism (should I say protocol?). I understand that a window has a defined size, and then queries its children, saying "my size is w x h, what would be your ideal size, buddy?", and then sometimes shrinks children when all children cant fit together at their ideal sizes. Any specific documentation on that, and on particular on when this happens during rendering? How are rendered "builtin" widgets? What kind of methods do they call on Widget base class? On the parent Window? When? Do they use pango.Layout? can you manually draw a TextView onto a pango.Layout object? This link gives an interesting example showing how you can draw content in a pango.Layout object and use it in a CellRenderer. I guess that I could adapt it if only I understood how TextView widget are rendered. Or perhaps, to put it more simply: given an existing widget instance, how does one render it at a specific gdk.Rectangle? Thanks a lot.

• C# comparing two files regex problem.

  - by Mike

  Hi everyone, what I'm trying to do is open a huge list of files (about 40k records, and match them on a line in a file that contains 2 millions records. And if my line from file A matches a line in file B write out that line. File A contains a bunch of files without extensions and file B contains full file paths including extensions. i'm using this but i cant get it to go... string alphaFilePath = (@"C:\Documents and Settings\g\Desktop\Arrp\Find\natst_ready.txt"); List<string> alphaFileContent = new List<string>(); using (FileStream fs = new FileStream(alphaFilePath, FileMode.Open)) using (StreamReader rdr = new StreamReader(fs)) { while (!rdr.EndOfStream) { alphaFileContent.Add(rdr.ReadLine()); } } string betaFilePath = @"C:\Documents and Settings\g\Desktop\Arryup\Find\eble.txt"; StringBuilder sb = new StringBuilder(); using (FileStream fs = new FileStream(betaFilePath, FileMode.Open)) using (StreamReader rdr = new StreamReader(fs)) { while (!rdr.EndOfStream) { string betaFileLine = rdr.ReadLine(); string matchup = Regex.Match(alphaFileContent, @"(\\)(\\)(\\)(\\)(\\)(\\)(\\)(\\)(.*)(\.)").Groups[9].Value; if (alphaFileContent.Equals(matchup)) { File.AppendAllText(@"C:\array_tech.txt", betaFileLine); } } } This doesnt work because the alphafilecontent is a single line only and i'm having a hard time figuring out how to get my regex to work on the file that contains all the file paths (Betafilepath) here is a sample of the beta file path. C:\arres_i\Grn\Ora\SEC\DBZ_EX1\Nes\001\DZO-EX00001.txt Here is the line i'm trying to compare from my alpha DZO-EX00001

• Can I create an application using SlimDX relying on the DirectX DLLs already bundled with Vista/Win7

  - by norheim.se

  I'm working on a .NET application that requires the use of accelerated graphics, currently DirectX 9.0c. The software is quite graphics intensive and must, in addition, be launchable from a CD or by ClickOnce without the user requiring administrator's permissions. I currently use SlimDX, which works great featurewise, but the users are getting rather annoyed by having to install the DirectX redistributable. Especially since this does require elevated permissions. It is rather hard to explain to them why the version of DirectX already bundled with their OS is not sufficient. After all - DirectX 9.0c has been around since 2004, and I'm not using any new fancy features. The ability to deliver an application that "just works" in Vista or Windows 7, without any particular additional prerequisites would be a huge advantage. Therefore: Is there any way I can build an application using DirectX 9.0c based on SlimDX, that relies only on the libraries provided in the standard Windows Vista/Win7 installation? That is - without requiring the additional DirectX redistributable to be installed? If not - is there any other managed (and preferably not abandoned) DirectX wrapper that can serve this purpose? Thanks in advance!

• Getting empty update rectangle in OnPaint after calling InvalidateRect on a layered window

  - by Shawn

  I'm trying to figure out why I've been getting an empty update rectangle when I call InvalidateRect on a transparent window. The idea is that I've drawn something on the window (it gets temporarily switched to have an alpha of 1/255 for the drawing), and then I switch it to full transparent mode (i.e. alpha of 0) in order to interact with the desktop & to be able to move the drawing around the screen on top of the desktop. When I try to move the drawing, I get its bounding rectangle & use it to call InvalidateRect, as such: InvalidateRect(m_hTarget, &winRect, FALSE); I've confirmed that the winRect is indeed correct, and that m_hTarget is the correct window & that its rectangle fully encompasses winRect. I get into the OnPaint handler in the class corresponding to m_hTarget, which is derived from a CWnd. In there, I create a CPaintDC, but when I try to access the update rectangle (dcPaint.m_ps.rcPaint) it's always empty. This rectangle gets passed to a function that determines if we need to update the screen (by using UpdateLayeredWindow in the case of a transparent window). If I hard-code a non-empty rectangle in here, the remaining code works correctly & I am able to move the drawing around the screen. I tried changing the 'FALSE' parameter to 'TRUE' in InvalidateRect, with no effect. I also tried using a standard CDC, and then using BeginPaint/EndPaint method in my OnPaint handler, just to ensure that CPaintDC wasn't doing something odd ... but I got the same results. The code that I'm using was originally designed for opaque windows. If m_hTarget corresponds to an opaque window, the same set of function calls results in the correct (i.e. non-empty) rectangle being passed to OnPaint. Once the window is layered, though, it doesn't seem to work right.

• Recover lost code from compiled apk

  - by AlexRamallo

  I have an issue here..and its making me really nervous. I was working on this game, and it was going great, so I took a copy of it on my laptop to work do some work while away from my computer. long story short, hard-drive failure + poor back ups led to me losing a very important class. Is there a way to decompile the apk to retrieve the bit of code that was lost? It isn't overly complicated or sophisticated, its just that its impossible to re-write it without reading every. single. line. of. code. in the entire application since it initializes a LOT of classes and loads a bunch of stuff in a specific way. With a quick google search I was able to find apktool, which decompiles it into a bunch of .smali files, which I don't think were designed for human reading. All I need to recover is one very big method in the class. I found the smali file that contains it and I think I found the line where it starts. something like .method public declared-synchronized load(Lcom/X/X/game/X;)I Anyone help would be appreciated since I would have to scrap the entire game without this method.

• File.Replace throwing IOException

  - by WebDevHobo

  I have an app that can make modify images. In some cases, this makes the filesize smaller, in some cases bigger. The program doesn't have an option to "not replace the file if result has a bigger filesize". So I wrote a little C# app to try and solve this. Instead of overwriting the files, I make the app write the result to a folder under the current one and name that folder Test. The C# app I wrote compares grabs the contents of both folders and puts the full path to the file(s) in two List objects. I then compare and replace. The replacing isn't working however. I get the following IOException: Unable to remove the file to be replaced The location is on an external hard-drive, on which I have full rights. Now, I know I can just do File.Delete and File.Move in that order, but this exception has gotten me interested in why this particular setup wont work. Here's the source code: http://pastebin.com/4Vq82Umu And yes, the file specified as last argument of the Replace function does exist.

• How to catch unintentional function interpositioning?

  - by SiegeX

  Reading through my book Expert C Programming, I came across the chapter on function interpositioning and how it can lead to some serious hard to find bugs if done unintentionally. The example given in the book is the following: my_source.c mktemp() { ... } main() { mktemp(); getwd(); } libc mktemp(){ ... } getwd(){ ...; mktemp(); ... } According to the book, what happens in main() is that mktemp() (a standard C library function) is interposed by the implementation in my_source.c. Although having main() call my implementation of mktemp() is intended behavior, having getwd() (another C library function) also call my implementation of mktemp() is not. Apparently, this example was a real life bug that existed in SunOS 4.0.3's version of lpr. The book goes on to explain the fix was to add the keyword static to the definition of mktemp() in my_source.c; although changing the name altogether should have fixed this problem as well. This chapter leaves me with some unresolved questions that I hope you guys could answer: Does GCC have a way to warn about function interposition? We certainly don't ever intend on this happening and I'd like to know about it if it does. Should our software group adopt the practice of putting the keyword static in front of all functions that we don't want to be exposed? Can interposition happen with functions introduced by static libraries? Thanks for the help. EDIT I should note that my question is not just aimed at interposing over standard C library functions, but also functions contained in other libraries, perhaps 3rd party, perhaps ones created in-house. Essentially, I want to catch any instance of interpositioning regardless of where the interposed function resides.

• Big-O for GPS data

  - by HH

  A non-critical GPS module use lists because it needs to be modifiable, new routes added, new distances calculated, continuos comparisons. Well so I thought but my team member wrote something I am very hard to get into. His pseudo code int k =0; a[][] <- create mapModuleNearbyDotList -array //CPU O(n) for(j = 1 to n) // O(nlog(m)) for(i =1 to n) for(k = 1 to n) if(dot is nearby) adj[i][j]=min(adj[i][j], adj[i][k] + adj[k][j]); His ideas transformations of lists to tables His worst case time complexity is O(n^3), where n is number of elements in his so-called table. Exception to the last point with Finite structure: O(mlog(n)) where n is number of vertices and m is an arbitrary constants Questions about his ideas why to waste resources to transform constantly-modified lists to table? Fast? only point where I to some extent agree but cannot understand the same upper limits n for each for-loops -- perhaps he supposed it circular why does the code take O(mlog(n)) to proceed in time as finite structure? The term finite may be wrong, explicit?

• Atomic operations on several transactionless external systems

  - by simendsjo

  Say you have an application connecting 3 different external systems. You need to update something in all 3. In case of a failure, you need to roll back the operations. This is not a hard thing to implement, but say operation 3 fails, and when rolling back, the rollback for operation 1 fails! Now the first external system is in an invalid state... I'm thinking a possible solution is to shut down the application and forcing a manual fix of the external system, but then again... It might already have used this information (and perhaps that's why it failed), or we might not have sufficient access. Or it might not even be a good way to rollback the action! Are there some good ways of handling such cases? EDIT: Some application details.. It's a multi user web application. Most of the work is done with scheduled jobs (through Quartz.Net), so most operations is run in it's own thread. Some user actions should trigger jobs that update several systems though. The external systems are somewhat unstable. I Was thinking of changing the application to use the Command and Unit Of Work pattern

• Will a Ph. D. in Computer Science help?

  - by Francisco Garcia

  I am close to my 30s and still learning about programming and software engineering. Like most people who like their profession I truly believe that I should aim to improve and keep updated. One of the things I do is reading technical papers from professional publications (IEEE and ACM) but I admit there are very good bloggers out there too. Lately I started to think (should I say realize?) that Ph. D people actually are expected to expand constantly their knowledge, but little is expected from lower classes once they know enough This made me think that maybe having a Ph. D will help to have more... respect? but I also believe that I am already getting old for that. Futhermore I see many master and doctor programs that does not seem to add any value over hard experience and self learning. I belive that a degree in computer science, althought not necessary, can lay out a good base for programming work. However: What can a Ph. D. degree give you that you cannot learn on your own? (if you are not into something VERY specific and want to work in a non academic environment)

• Where should global Application Settings be stored on Windows 7?

  - by Kerido

  Hi everybody, I'm working hard on making my product work seamlessly on Windows 7. The problem is that there is a small set of global (not user-specific) application settings that all users should be able to change. On previous versions I used HKLM\Software\__Company__\__Product__ for that purpose. This allowed Power Users and Administrators to modify the Registry Key and everything worked correctly. Now that Windows Vista and Windows 7 have this UAC feature, by default, even an Administrator cannot access the Key for writing without elevation. A stupid solution would, of course, mean adding requireAdministrator option into the application manifest. But this is really unprofessional since the product itself is extremely far from administration-related tasks. So I need to stay with asInvoker. Another solution could mean programmatic elevation during moments when write access to the Registry Key is required. Let alone the fact that I don't know how to implement that, it's pretty awkward also. It interferes with normal user experience so much that I would hardly consider it an option. What I know should be relatively easy to accomplish is adding write access to the specified Registry Key during installation. I created a separate question for that. This also very similar to accessing a shared file for storing the settings. My feeling is that there must be a way to accomplish what I need, in a way that is secure, straightforward and compatible with all OS'es. Any ideas?

• Maintenance tool for Application Database

  - by Thierry

  Hello ! Does anybody know about a good tool which help maintaining the database of an application ? I'm working on an application which uses a database (Microsoft Sql Server). When a development requires to change something in the database (e.g., structure, data migration...), we create a script (Transact-SQL script) and add it into our revision control tool (subversion - that tool also contains our code). Each script must add a line in a log table to keep a trace of all the scripts that have been ran into a database. In order to build a database for our application, one needs to run all scripts ordered by their creation date. I'm not really happy with this technique notably because it make application migration a bit hard. If we want to install a new version of the application somewhere, e.g., migrate from version 1.3 to 2.1, we must get all the scripts between these two versions. Then run them and ensure that everything is done in a transaction... For sure we could built home-made tools to help but I wonder if some tools already exists to do that kind of job.

  hi, I pieced together the script below from various tutorials, examples, etc... Right now the script currently: Saves Id, Name, Url with a "|" delimiter to a text file Db like: 1|John|http://www.john.com| 2|Mark|http://www.mark.com| 3|Fred|http://www.fred.com| But I'm having a hard time trying to make the "UPDATE" and "DELETE" buttons work. Can someone please post code which will: let me update/save any changed data for that row (for UPDATE button) let me delete that row (for DELETE button) PLEASE copy n paste the code below and try for yourself. I would like to keep the output format of the script below too. thanks D- $file = "data.txt"; $name = $_POST['name']; $url = $_POST['url']; $data = file('data.txt'); $i = 1; foreach ($data as $line) { $line = explode('|', $line); $i++; } if (isset($_POST['submits'])) { $fp = fopen($file, "a+"); fwrite($fp, $i."|".$name."|".$url."|\n"); fclose($fp); } ?

• How slow are bit fields in C++

  - by Shane MacLaughlin

  I have a C++ application that includes a number of structures with manually controlled bit fields, something like #define FLAG1 0x0001 #define FLAG2 0x0002 #define FLAG3 0x0004 class MyClass { ' ' unsigned Flags; int IsFlag1Set() { return Flags & FLAG1; } void SetFlag1Set() { Flags |= FLAG1; } void ResetFlag1() { Flags &= 0xffffffff ^ FLAG1; } ' ' }; For obvious reasons I'd like to change this to use bit fields, something like class MyClass { ' ' struct Flags { unsigned Flag1:1; unsigned Flag2:1; unsigned Flag3:1; }; ' ' }; The one concern I have with making this switch is that I've come across a number of references on this site stating how slow bit fields are in C++. My assumption is that they are still faster than the manual code shown above, but is there any hard reference material covering the speed implications of using bit fields on various platforms, specifically 32bit and 64bit windows. The application deals with huge amounts of data in memory and must be both fast and memory efficient, which could well be why it was written this way in the first place.

• Reverse-projection 2D points into 3D

  - by ehsan baghaki

  Suppose we have a 3d Space with a plane on it with an arbitary equation : ax+by+cz+d=0 now suppose that we pick 3 random points on that plane: (x0,y0,z0) (x1,y1,z1) (x1,y1,z1) now i have a different point of view(camera) for this plane. i mean i have a different camera that will look at this plane from a different point of view. From that camera point of view these points have different locations. for example (x0,y0,z0) will be (x0',y0') and (x1,y1,z1) will be (x1',y1') and (x2,y2,z2) will be (x2',y2') from the new camera point of view. So here is my a little hard question! I want to pick a point for example (X,Y) from the new camera point of view and tell where it will be on that plane. All i know is that 3 points and their locations on 3d space and their projection locations on the new camera view. Do you know the coefficients of the plane-equation and the camera positions (along with the projection), or do you only have the six points? - Nils i know the location of first 3 points. therefore we can calculate the coefficients of the plane. so we know exactly where the plane is from (0,0,0) point of view. and then we have the camera that can only see the points! So the only thing that camera sees is 3 points and also it knows their locations in 3d space (and for sure their locations on 2d camera view plane). and after all i want to look at camera view, pick a point (for example (x1,y1)) and tell where is that point on that plane. (for sure this (X,Y,Z) point should fit on the plane equation). Also i know nothing about the camera location.

• "Function object is unsubscriptable" in basic integer to string mapping function

  - by IanWhalen

  I'm trying to write a function to return the word string of any number less than 1000. Everytime I run my code at the interactive prompt it appears to work without issue but when I try to import wordify and run it with a test number higher than 20 it fails as "TypeError: 'function' object is unsubscriptable". Based on the error message, it seems the issue is when it tries to index numString (for example trying to extract the number 4 out of the test case of n = 24) and the compiler thinks numString is a function instead of a string. since the first line of the function is me defining numString as a string of the variable n, I'm not really sure why that is. Any help in getting around this error, or even just help in explaining why I'm seeing it, would be awesome. def wordify(n): # Convert n to a string to parse out ones, tens and hundreds later. numString = str(n) # N less than 20 is hard-coded. if n < 21: return numToWordMap(n) # N between 21 and 99 parses ones and tens then concatenates. elif n < 100: onesNum = numString[-1] ones = numToWordMap(int(onesNum)) tensNum = numString[-2] tens = numToWordMap(int(tensNum)*10) return tens+ones else: # TODO pass def numToWordMap(num): mapping = { 0:"", 1:"one", 2:"two", 3:"three", 4:"four", 5:"five", 6:"six", 7:"seven", 8:"eight", 9:"nine", 10:"ten", 11:"eleven", 12:"twelve", 13:"thirteen", 14:"fourteen", 15:"fifteen", 16:"sixteen", 17:"seventeen", 18:"eighteen", 19:"nineteen", 20:"twenty", 30:"thirty", 40:"fourty", 50:"fifty", 60:"sixty", 70:"seventy", 80:"eighty", 90:"ninety", 100:"onehundred", 200:"twohundred", 300:"threehundred", 400:"fourhundred", 500:"fivehundred", 600:"sixhundred", 700:"sevenhundred", 800:"eighthundred", 900:"ninehundred", } return mapping[num] if __name__ == '__main__': pass

• How to speed up a slow UPDATE query

  - by Mike Christensen

  I have the following UPDATE query: UPDATE Indexer.Pages SET LastError=NULL where LastError is not null; Right now, this query takes about 93 minutes to complete. I'd like to find ways to make this a bit faster. The Indexer.Pages table has around 506,000 rows, and about 490,000 of them contain a value for LastError, so I doubt I can take advantage of any indexes here. The table (when uncompressed) has about 46 gigs of data in it, however the majority of that data is in a text field called html. I believe simply loading and unloading that many pages is causing the slowdown. One idea would be to make a new table with just the Id and the html field, and keep Indexer.Pages as small as possible. However, testing this theory would be a decent amount of work since I actually don't have the hard disk space to create a copy of the table. I'd have to copy it over to another machine, drop the table, then copy the data back which would probably take all evening. Ideas? I'm using Postgres 9.0.0. UPDATE: Here's the schema: CREATE TABLE indexer.pages ( id uuid NOT NULL, url character varying(1024) NOT NULL, firstcrawled timestamp with time zone NOT NULL, lastcrawled timestamp with time zone NOT NULL, recipeid uuid, html text NOT NULL, lasterror character varying(1024), missingings smallint, CONSTRAINT pages_pkey PRIMARY KEY (id ), CONSTRAINT indexer_pages_uniqueurl UNIQUE (url ) ); I also have two indexes: CREATE INDEX idx_indexer_pages_missingings ON indexer.pages USING btree (missingings ) WHERE missingings > 0; and CREATE INDEX idx_indexer_pages_null ON indexer.pages USING btree (recipeid ) WHERE NULL::boolean; There are no triggers on this table, and there is one other table that has a FK constraint on Pages.PageId.

• Loading city/state from SQL Server to Google Maps?

  - by knawlejj

  I'm trying to make a small application that takes a city & state and geocodes that address to a lat/long location. Right now I am utilizing Google Map's API, ColdFusion, and SQL Server. Basically the city and state fields are in a database table and I want to take those locations and get marker put on a Google Map showing where they are. This is my code to do the geocoding, and viewing the source of the page shows that it is correctly looping through my query and placing a location ("Omaha, NE") in the address field, but no marker, or map for that matter, is showing up on the page: function codeAddress() { <cfloop query="GetLocations"> var address = document.getElementById(<cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput>).value; if (geocoder) { geocoder.geocode( {<cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput>: address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location, title: <cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput> }); } else { alert("Geocode was not successful for the following reason: " + status); } }); } </cfloop> } And here is the code to initialize the map: var geocoder; var map; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.4167,-90.4290); var myOptions = { zoom: 5, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } var marker = new google.maps.Marker({ position: latlng, map: map, title: "Test" }); map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } I do have a map working that uses lat/long that was hard coded into the database table, but I want to be able to just use the city/state and convert that to a lat/long. Any suggestions or direction? Storing the lat/long in the database is also possible, but I don't know how to do that within SQL.

• Hide All But First Matching Element

  - by Batfan

  I am using jquery to sort through multiple paragraphs. Currently I have it set to show only paragraphs that start with a current letter. But now, I would like to consolidate further. If the text between the paragraph tags has multiple instances, I would like all but the first hidden. This is what I have so far but, it is not working. var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ jQuery(this).addClass('current-series'); jQuery(this).html(letter + '<span class="hidden">'+jQuery(this).text().slice(1)+ '</span>'); } else{ jQuery(this).hide();} }) } Update: Sorry guys, I know this is kind of hard to explain. Here's a basic example: The selected letter is B The values returned are: Ball Ball Ball Boy Brain Bat Bat Each of these values is in a paragraph tag. Is there a way to consolidate to this? Ball Boy Brain Bat

• How to combine these two PHP arrays ?

  - by Annan

  I have two arrays in php that are part of an image management system. weighted_images A multidimensional array. Each sub array is an associative array with keys of 'weight' (for ordering by) and 'id' (the id of the image). array( 156 => array('weight'=>1, 'id'=>156), 784 => array('weight'=>-2, 'id'=>784), ) images This array is user input. It's an array of image ids. array(784, 346, 748) I want to combine them in to a single array of ids ordered by the weight of the image. If an image doesn't have a weight append to the end. It's not a particularly hard problem however my solution is far from elegant and can't help thinking that there must be a better way to do this. $t_images = array(); foreach ($weighted_images as $wi) { if ( in_array($wi['id'], $images) ) { $t_images[$wi['weight']] = $wi['id']; } } foreach ($images as $image) { if ( !$weighted_images[$image] ) { $t_images[] = $image; } } $images = $t_images; Question: Is there a better way to do this?

• Why would the same web form control render different "onclick" logic based on the page structure?

  - by zk812

  It was hard to title this question. :) I have a user control that is used to display a list of lookup items in my database and a delete button for each item (Editor User Control below). The delete button has an onClientClick event used to display a confirmation dialog in JavaScript. On page one, the confirmation pops up and functions correctly. The overall structure is: Master Page Page Editor User Control List of items with delete button On page two, the confirmation pops up but regardless of the answer, the page posts back anyway. The structure of this page is: Master Page Page User Control Editor User Control List of items with delete button For some reason, this makes a difference in how the delete button is rendered. Page one: <input type="image" name="ctl00...RequestTypesDataList$ctl01$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(1);" /> Page two: <input type="image" name="ctl00...RequestTypesDataList$ctl07$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(2);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$ContentPlaceHolder1$RequestCreator1$RequestTypeEditor1$RequestTypesDataList$ctl07$ctl01&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" /> Does anyone know why page two renders WebForm_DoPostBackWithOptions after my JS check? It's causing the postback regardless of the confirmation choice.
