• Register new memer for vBulletin via Mobile API

  - by Nikolay Stariradeff

  I'm trying to use the vBulletin REST Mobile API to simply register. The sourced are installed on my local machine and according the documentation https://www.vbulletin.com/forum/content.php/393-User-Registration-Process-Mobile-API This procedure should not be so hard, especially without humanity and COPPA authentication. However I've stacked! The method definition describes "addnewmember" clear, so I've generated a test link, which should do the job. https://www.vbulletin.com/forum/content.php/365-User-Related-Methods The link is: .../forum/api.php?&api_m=register_addmember&api_c=1&api_s=76ec9eec61e7fdfef2f3feee28d5f392&api_sig=8fe54313b333cc0fef4ddd8e398b5c80&api_v=6&agree=1&username=testuser&email=XXXXXX%40gmail.com&emailconfirm=XXXXX%40gmail.com&password=12345678&passwordconfirm=12345678 As a response I get: register_not_agreed The Docs: register_not_agreed The agree parameter should be set to 1. Which is also clear - agree parameter was not there. Here comes the funny part - In the API-Log I can see that the 'agree' parameter is correctly passed *1 test_client Gast 13:23, 18.06.2012 register_addmember Array ( [api_m] = register_addmember [api_c] = 1 [api_s] = 76ec9eec61e7fdfef2f3feee28d5f392 [api_sig] = 8fe54313b333cc0fef4ddd8e398b5c80 [api_v] = 6 [agree] = 1 [username] = testuser [email] = ....* Is there anybody with experience with the Mobile API that could help?

• Carriage Return\Line feed in Java

  - by Manu

  Guys, i have created text file in unix enviroment using java code. For writing the text file i am using java.io.FileWriter and BufferedWriter. and for newline after each row i am using bw.newLine() method. (where bw is object of BufferedWriter ) and sending that text file by attaching in mail from unix environment itself (automated that using unix commands). My issue is, after i download the text file from mail in windows system, if i opened that text file the data's are not properly aligned. newline() character is not working i think so. I want same text file alignment as it is in unix environment, if i opened the text file in windows environment also. How to resolve the problem.Please help ASAP. Thanks for your help in advance. pasting my java code here for your reference..(running java code in unix environment) File f = new File(strFileGenLoc); BufferedWriter bw = new BufferedWriter(new FileWriter(f, false)); rs = stmt.executeQuery("select * from jpdata"); while ( rs.next() ) { bw.write(rs.getString(1)==null? "":rs.getString(1)); bw.newLine(); }

• PHP's openssl_sign generates different signature than SSCrypto's sign

  - by pascalj

  I'm writing an OS X client for a software that is written in PHP. This software uses a simple RPC interface to receive and execute commands. The RPC client has to sign the commands he sends to ensure that no MITM can modify any of them. However, as the server was not accepting the signatures I sent from my OS X client, I started investigating and found out that PHP's openssl_sign function generates a different signature for a given private key/data combination than the Objective-C SSCrypto framework (which is only a wrapper for the openssl lib): SSCrypto *crypto = [[SSCrypto alloc] initWithPrivateKey:self.localPrivKey]; NSData *shaed = [self sha1:@"hello"]; [crypto setClearTextWithData:shaed]; NSData *data = [crypto sign]; generates a signature like CtbkSxvqNZ+mAN... The PHP code openssl_sign("hello", $signature, $privateKey); generates a signature like 6u0d2qjFiMbZ+... (For my certain key, of course. base64 encoded) I'm not quite shure why this is happening and I unsuccessfully experimented with different hash-algorithms. As the PHP documentation states SHA1 is used by default. So why do these two functions generate different signatures and how can I get my Objective-C part to generate a signature that PHPs openssl_verify will accept? Note: I double checked that the keys and the data is correct!

• Can I get debug symbols for flash player? Or any other way to get support for flash?

  - by Tim

  The company I am working for has a flash component (using flex and cs4) that crashes intermittently in chrome, FF and IE. (so far only win32 platforms) I submitted a bug report to Adobe but have not heard anything back from them. Their support process seems like a black hole. WE can get a dump from Flash using these steps but after submitting the bug we got no help at all. We loaded this into MS visual studio but can;t get decent stack information because there are no symbols for the flash stuff. Microsoft and other companies provide symbols to help with debugging and we would like to get that from adobe. Is there any way to make progress on this? Does anyone know where to get flash symbols or how else we can make progress? It is hard to debug the process if the container just dies. the binary is flash10c.ocx I just spent a painful hour on the phone with adobe folks - and the final answer from one of them (I spoke to about 8 people) was that they do not have a per incident purchase plan for developer support for flash. I find that hard to believe. Does anyone know how to get support for Flash?

• How to use Java on Google App Engine without exceeding minute quotas?

  - by Geo

  A very simple java code inside a doGet() servlet is getting more than a second of cpu time on GAE. I have read some quota related documentation and apparently I am not doing anything wrong. //Request the user Agent info String userAgent = req.getHeader("User-Agent"); I wanted to know what was using the CPU the most, I use a google help recommendation. //The two lines below will get the CPU before requesting User-Agent Information QuotaService qs = QuotaServiceFactory.getQuotaService(); long start = qs.getCpuTimeInMegaCycles(); //Request the user Agent info String userAgent = req.getHeader("User-Agent"); //The three lines below will get the CPU after requesting User-Agent Information // and informed it to the application log. long end = qs.getCpuTimeInMegaCycles(); double cpuSeconds = qs.convertMegacyclesToCpuSeconds(end - start); log.warning("CPU Seconds on geting User Agent: " + cpuSeconds); The only thing that the code above tells me is that inspecting the header will use more than a second (1000ms) of cpu time, which for Google is a warning on the log panel. That seems to be a very simple request and still is using more than a second of cpu. What I am missing?

• Properly maintain sorted state of Array/Set

  - by Jeff

  I'm trying to get data out of my MOC and then create some new objects based on those objects, and put it all back together, while keeping my sort state. The securities come out of the MOC in proper order. And everything seems to be fine until I do the assignment to the game at the bottom from setWithArray. The documentation says that setWithArray removed the duplicate objects, if there are any. I'm wonder if that's messing up my data, but I don't see a good alternative. The data is ultimately being pulled out into a UITableView. When I add items to the game manually, then they stay sorted, so I don't think the breaking of the sort is beyond the scope of what I've included here. NSError *error; NSArray *allTheSecurities = [managedObjectContext executeFetchRequest:request error:&error]; if (allTheSecurities == nil) { // Handle the error. } [request release]; /**/ NSLog( @"Enumerate..." ); NSEnumerator *enumerator = [allTheSecurities objectEnumerator]; id anObject; NSMutableArray *portfolioStocks = [[NSMutableArray alloc] init]; while (anObject = [enumerator nextObject]) { NSLog( @"Iteration... %@", [anObject name] ); NSLog( @"Build a stock..." ); PortfolioStocks *this_stock = (PortfolioStocks *)[NSEntityDescription insertNewObjectForEntityForName:@"PortfolioStocks" inManagedObjectContext:context]; NSLog( @"Set a value..." ); [this_stock setSecurity:(Security *)anObject]; [this_stock setQuantity:[NSNumber numberWithInt:0]]; NSLog( @"Add to portfolioStocks..." ); [portfolioStocks addObject:this_stock]; } //Sorted properly up to here! NSLog( @"Add to portfolio..." ); [game setPortfolio:[NSSet setWithArray:portfolioStocks]]; // <-- This is where it's not sorted anymore.

• Unable to use certain Fonts programatically in ASP.Net

  - by TooFat

  I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

• Standard and reliable mouse-reporting with GLUT

  - by Victor

  Hello! I'm trying to use GLUT (freeglut) in my OpenGL application, and I need to register some callbacks for mouse wheel events. I managed to dig out a fairly undocumented function: api documentation But the man page and the API entry for this function both state the same thing: Note: Due to lack of information about the mouse, it is impossible to implement this correctly on X at this time. Use of this function limits the portability of your application. (This feature does work on X, just not reliably.) You are encouraged to use the standard, reliable mouse-button reporting, rather than wheel events. Fair enough, but how do I use this standard, reliable mouse-reporting? And how do I know which is the standard? Do I just use glutMouseFunc() and use button values like 4 and 5 for the scroll up and down values respectively, say if 1, 2 and 3 are the left, middle and right buttons? Is this the reliable method? Bonus question: it seems the `xev' tool is reporting different values for my buttons. My mouse buttons are numbered from 1 to 5 with xev, but glut is reporting buttons from 0 to 4, i.e. an off-by-one. Is this common?

• How do I search & replace all occurrences of a string in a ms word doc with python?

  - by Mark

  Hello there, I am pretty stumped at the moment. Based on http://stackoverflow.com/questions/1045628/can-i-use-win32-com-to-replace-text-inside-a-word-document I was able to code a simple template system that generates word docs out of a template word doc (in Python). My problem is that text in "Text Fields" is not find that way. Even in Word itself there is no option to search everything - you actually have to choose between "Main Document" and "Text Fields". Being new to the Windows world I tried to browse the VBA docs for it but found no help (probably due to "text field" being a very common term). word.Documents.Open(f) wdFindContinue = 1 wdReplaceAll = 2 find_str = '\{\{(*)\}\}' find = word.Selection.Find find.Execute(find_str, False, False, True, False, False, \ True, wdFindContinue, False, False, False) while find.Found: t = word.Selection.Text.__str__() r = process_placeholder(t, answer_data, question_data) if type(r) == dict: errors.append(r) else: find.Execute(t, False, True, False, False, False, \ True, False, False, r, wdReplaceAll) This is the relevant portion of my code. I was able to get around all problems by myself by now (hint: if you want to replace strings with more than 256 chars, you have to do it via clipboard, etc ...) Hope, someone can help me.

• Basic question on retain/release semantics from Apple's reference library

  - by davetron5000

  I have done Objective-C way back when, and have recently (i.e. just now) read the documentation on Apple's site regarding the use of retain and release. However, there is a bit of code in their Creating an iPhone Application page that has me a bit confused: - (void)setUpPlacardView { // Create the placard view -- it calculates its own frame based on its image. PlacardView *aPlacardView = [[PlacardView alloc] init]; self.placardView = aPlacardView; [aPlacardView release]; // What effect does this have on self.placardView?! placardView.center = self.center; [self addSubview:placardView]; } Not seeing the entire class, it seems that self.placardView is also a PlacardView * and the assignment of it to aPlacardView doesn't seem to indicate it will retain a reference to it. So, it appears to me that the line I've commented ([aPlacardView release];) could result in aPlacardView having a retain count of 0 and thus being deallocated. Since self.placardView points to it, wouldn't that now point at deallocated memory and cause a problem?

• When and why can sprintf fail?

  - by Srekel

  I'm using swprintf to build a string into a buffer (using a loop among other things). const int MaxStringLengthPerCharacter = 10 + 1; wchar_t* pTmp = pBuffer; for ( size_t i = 0; i < nNumPlayers ; ++i) { const int nPlayerId = GetPlayer(i); const int nWritten = swprintf(pTmp, MaxStringLengthPerCharacter, TEXT("%d,"), nPlayerId); assert(nWritten >= 0 ); pTmp += nWritten; } *pTaskPlayers = '\0'; If during testing the assert never hits, can I be sure that it will never hit in live code? That is, do I need to check if nWritten < 0 and handle that, or can I safely assume that there won't be a problem? Under which circumstances can it return -1? The documentation more or less just states "If the function fails". In one place I've read that it will fail if it can't match the arguments (i.e. the formatting string to the varargs) but that doesn't worry me. I'm also not worried about buffer overrun in this case - I know the buffer is big enough.

• Is the Java classpath final after JVM startup?

  - by Jens

  Hi, I have read a lot about the Java class loading process lately. Often I came across texts that claimed that it is not possible to add classes to the classpath during runtime and load them without class loader hackery (URLClassLoaders etc.) As far as I know classes are loaded dynamically. That means their bytecode representation is only loaded and transformed to a java.lang.Class object when needed. So shouldn't it be possible to add a JAR or *.class file to the classpath after the JVM started and load those classes, provided they haven't been loaded yet? (To be clear: In this case the classpath is simple folder on the filesystem. "Adding a JAR or *.class file" simply means dropping them in this folder.) And if not, does that mean that the classpath is searched on JVM startup and all fully qualified names of the found classes are cached in an internal "list"? It would be nice of you if you could point me to some sources in your answers. Preferably the offical SUN documentation: Sun JVM Spec. I have read the spec but could not find anything about the classpath and if it's finalized on JVM startup. P.s. This is a theoretical question. I just want to know if it is possible. There is nothing practical I want to achieve. There is just my thirst for knowledge :)

• Low Level Console Input

  - by Soulseekah

  I'm trying to send commands to to the input of a cmd.exe application using the low level read/write console functions. I have no trouble reading the text (scraping) using the ReadConsole...() and WriteConsole() functions after having attached to the process console, but I've not figured out how to write for example "dir" and have the console interpret it as a sent command. Here's a bit of my code: CreateProcess(NULL, "cmd.exe", NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi); AttachConsole(pi.dwProcessId); strcpy(buffer, "dir"); WriteConsole(GetStdHandle(STD_INPUT_HANDLE), buffer, strlen(buffer), &charRead, NULL); STARTUPINFO attributes of the process are all set to zero, except, of course, the .cb attribute. Nothing changes on the screen, however I'm getting an Error 6: Invalid Handle returned from WriteConsole to STD_INPUT_HANDLE. If I write to (STD_OUTPUT_HANDLE) I do get my dir written on the screen, but nothing of course happens. I'm guessing SetConsoleMode() might be of help, but I've tried many mode combinations, nothing helped. I've also created a quick console application that waits for input (scanf()) and echoes back whatever goes in, didn't work. I've also tried typing into the scanf() promp and then peek into the input buffer using PeekConsoleInput(), returns 0, but the INPUT_RECORD array is empty. I'm aware that there is another way around this using WriteConsoleInput() to directly inject INPUT_RECORD structured events into the console, but this would be way too long, I'll have to send each keypress into it. I hope the question is clear. Please let me know if you need any further information. Thanks for your help.

• Eclipse PDT "tips" ?

  - by Pascal MARTIN

  Hi ! (Yes, this is a quite opened and general and subjective question -- it's by design, cause I want tips you think are great !) I'm using Eclipse PDT 2.1 to work in PHP, either for small and/or big projects -- I've been doing so for quite some times, now, actually (since before 1.0 stable, if I remember well)... I was wondering if any of you did know "tips" to be more efficient. Let met explain more in details : I know about things like plugins like Aptana (better editor for JS/CSS), Subversive (for SVN access), RSE, Filesync, integrating Xdebug's debugger, ... What I mean by "tips" is more some little things you discovered one day and since use all the time -- and allow you to be more efficient in your PHP projects. Some examples of "tips" that come to my mind, and that already know and use : ctrl+space to open the list of suggestions for functions / variables names ctrl+shift+R (navigate > open resource) to open a popup which show only files which names contain what you type ; ie, quick opening of files this one might be the perfect example : I know this one is not often known by coworkers and they find it as useful as I do ; so, I guess there might be lots of other things like this one I don't know myself ^^ ctrl+M to switch to full-screen view for the editor (instead of double-click on tabs bar) shift+F2 while on a function name, to open it's page if the PHP manual in a browser Attention Mac Users use Command instead Control. I guess you get the point ; but I'm really open to any suggestion (be it eclipse-related in general, of more PHP/PDT-specific) that can help be be more efficient :-) Anyway, thanks in advance for your help !

• How would I find all sets of N single-digit, non-repeating numbers that add up to a given sum in PHP

  - by TerranRich

  Let's say I want to find all sets of 5 single-digit, non-repeating numbers that add up to 30... I'd end up with [9,8,7,5,1], [9,8,7,4,2], [9,8,6,4,3], [9,8,6,5,2], [9,7,6,5,3], and [8,7,6,5,4]. Each of those sets contains 5 non-repeating digits that add up to 30, the given sum. Any help would be greatly appreciated. Even just a starting point for me to use would be awesome. I came up with one method, which seems like a long way of going about it: get all unique 5-digit numbers (12345, 12346, 12347, etc.), add up the digits, and see if it equals the given sum (e.g. 30). If it does, add it to the list of possible matching sets. I'm doing this for a personal project, which will help me in solving Kakuro puzzles without actually solving the whole thing at once. Yeah, it may be cheating, but it's... it's not THAT bad... :P

• Axis2 SOAP Envelope Header Information

  - by BigZig

  I'm consuming a web service that places an authentication token in the SOAP envelope header. It appears (through looking at the samples that came with the WS WSDL) that if the stub is generated in .NET, this header information is exposed through a member variable in the stub class. However, when I generate my Axis2 java stub using WSDL2Java it doesn't appear to be exposed anywhere. What is the correct way to extract this information from the SOAP envelope header? WSDL: http://www.vbar.com/zangelo/SecurityService.wsdl C# Sample: using System; using SignInSample.Security; // web service using SignInSample.Document; // web service namespace SignInSample { class SignInSampleClass { [STAThread] static void Main(string[] args) { // login to the Vault and set up the document service SecurityService secSvc = new SecurityService(); secSvc.Url = "http://localhost/AutodeskDM/Services/SecurityService.asmx"; secSvc.SecurityHeaderValue = new SignInSample.Security.SecurityHeader(); secSvc.SignIn("Administrator", "", "Vault"); DocumentServiceWse docSvc = new DocumentServiceWse(); docSvc.Url = "http://localhost/AutodeskDM/Services/DocumentService.asmx"; docSvc.SecurityHeaderValue = new SignInSample.Document.SecurityHeader(); docSvc.SecurityHeaderValue.Ticket = secSvc.SecurityHeaderValue.Ticket; docSvc.SecurityHeaderValue.UserId = secSvc.SecurityHeaderValue.UserId; } } } The sample illustrates what I'd like to do. Notice how the secSvc instance has a SecurityHeaderValue member variable that is populated after a successful secSvc.SignIn() invocation. Here's some relevant API documentation regarding the SignIn method: Although there is no return value, a successful sign in will populate the SecurityHeaderValue of the security service. The SecurityHeaderValue information is then used for other web service calls.

• Distinct Value Array for View Controller Index Using Core Data

  - by b.dot

  Hi, I'm trying to create an index representing the first letter value of each record in a Core Data store to be used in a table view controller. I'm using a snippet of the code from Apple's documentation. I would simply like to produce an array or dictionary of distinct values as the result. My store already has the character defined within each record object. Questions: 1) I'm having a problem understanding NSDictionaryResultType. Where does the resulting dictionary object get received so that I can assign it's keys to the view controller? The code seems to only return an array. 2) If I include the line containing NSDictionaryResultType, I get no returns. 3) I realize that I could do this in a loop, but I'm hoping this will work. Thanks! NSEntityDescription *entity = [NSEntityDescription entityForName:@"People" inManagedObjectContext:managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:entity]; [request setResultType:NSDictionaryResultType]; // This line causes no no results. [request setReturnsDistinctResults:YES]; [request setPropertiesToFetch :[NSArray arrayWithObject:@"alphabetIndex"]]; NSError *error; NSArray *objects = [managedObjectContext executeFetchRequest:request error:&error];

• Intermittent Issue Writing to Google Appengine Datastore

  - by user242153

  Hi, I have a functioning app and recently have had intermittent problems writing to the datastore. I did not make any relevant code changes, however in the last few days my attempts to write to the datastore sometimes work and sometimes don't. I am trying to save an object that is in a many to one relationship with an existing persisted parent. So, the logic works like this: 1) Parent pulled from the datastore 2) Child created / instantiated using constructor 3) Parent.addSingleChild(child); // the "addSingleChild" method just adds the object argument to the collection of children 4) child.setParent(Parent); // sets the Parent object to the parent field I am using transactions as explained in the documentation ending with "finally {if (tx.isActive()) {tx.rollback(); } }" When the servlet is called, the parent is called from the datastore and the child object is created and added to the many to one mapping to the pre-existing parent. The child should automatically be persisted, since the parent is already persistent, and the child is added to the collection of children that map to the parent. And it worked this way in the past. However, to be sure, i did add a pm.makePersistent(child). Doesn't seem to help, still have the intermittent problem. Any suggestions would be appreciated, and if you need to see the actual code I can post. Thanks

• PreparedStatement question in Java against Oracle.

  - by fardon57

  Hi everyone, I'm working on the modification of some code to use preparedStatement instead of normal Statement, for security and performance reason. Our application is currently storing information into an embedded derby database, but we are going to move soon to Oracle. I've found two things that I need your help guys about Oracle and Prepared Statement : 1- I've found this document saying that Oracle doesn't handle bind parameters into IN clauses, so we cannot supply a query like : Select pokemon from pokemonTable where capacity in (?,?,?,?) Is that true ? Is there any workaround ? ... Why ? 2- We have some fields which are of type TIMESTAMP. So with our actual Statement, the query looks like this : Select raichu from pokemonTable where evolution = TO_TIMESTAMP('2500-12-31 00:00:00.000', 'YYYY-MM-DD HH24:MI:SS.FF') What should be done for a prepared Statement ? Should I put into the array of parameters : 2500-12-31 or TO_TIMESTAMP('2500-12-31 00:00:00.000', 'YYYY-MM-DD HH24:MI:SS.FF') ? Thanks for your help, I hope my questions are clear ! Regards,

• Sort command not working as expected

  - by user964689

  If anybody can help me to write a loop to iterate over files in a folder it would save me a huge amount of time. I think it must be quite a simple solution ,but I currently don't know how to nest a loop within a loop. So far I have this script: cd /folderlocation/ for i in `</textfile_containing_lines_to_iterate_through` do #size=`echo $i | perl -nE '/:([\d-]+)/ && say abs(eval $1)'` #echo "$size" zcat dataset | head -n 18 > temp"$i".vcf tabix dataset $i >> temp"$i".vcf vcftools --window-pi 1000000 --vcf temp10individuals"$i".vcf >> run_summary.txt cat out.windowed.pi >> outputfile_2 #rm temp* done grep -v "PI" outputfile_2 > outputfile rm outputfile_2 I need to expand this so that the script will run multiple times, through all of the 'textfiles_containing_lines_to_iterate_through'. Currently I change the name of the textfile manually each time and re-run the script. So I'd need a loop that does this for file in folder, and also that uses the name of the file as part of the outputfile name so that I can match an output file to an inputfile. Any help would be really useful and greatly appreciated! Many thanks in advance.

• URL protocol handler shell execute problem

  - by Chuck

  Hi, I'm working on a small hobby web site where I'm able to launch a local app with certain arguments based on links. Setting up a protocol wasn't difficult, as described in http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx, but I have one dilemma: Let's say the protocol is: foo:127.0.0.1:1111, so a link like href="foo:127.0.0.1:1111" would launch an app like: bar.exe "%1". Since I don't have any control over bar.exe (if I had, then it would be no problem to just parse it, obviously), I need some help parsing %1. bar.exe will launch correctly if it's run as bar.exe 127.0.0.1:1111, but not if it's run as bar.exe foo:127.0.0.1:1111. So I guess my question is... is there ANY way to tell the registry to pass on not %1, but a trimmed %1? (Thinking in terms of regexp where you have match[0] = all of the matched, match[1] = first capture in the matched text). I can solve it by having a .bat instead of .exe, but as I would like to make it as easy as possible for the user to use, I would LOVE it if I could handle it all stricly in registry. Any help is greatly appreciated! Chuck

• Make Errors: Missing Includes in C++ Script?

  - by Abs

  Hello all, I just got help in how to compile this script a few mintues ago on SO but I have managed to get errors. I am only a beginner in C++ and have no idea what the below erros means or how to fix it. This is the script in question. I have read the comments from some users suggesting they changed the #include parts but it seems to be exactly what the script has, see this comment. [root@localhost wkthumb]# qmake-qt4 && make g++ -c -pipe -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/qt4/mkspecs/linux-g++ -I. -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include -I. -I. -I. -o main.o main.cpp main.cpp:5:20: error: QWebView: No such file or directory main.cpp:6:21: error: QWebFrame: No such file or directory main.cpp:8: error: expected constructor, destructor, or type conversion before ‘*’ token main.cpp:11: error: ‘QWebView’ has not been declared main.cpp: In function ‘void loadFinished(bool)’: main.cpp:18: error: ‘view’ was not declared in this scope main.cpp:18: error: ‘QWebSettings’ has not been declared main.cpp:19: error: ‘QWebSettings’ has not been declared main.cpp:20: error: ‘QWebSettings’ has not been declared main.cpp: In function ‘int main(int, char**)’: main.cpp:42: error: ‘view’ was not declared in this scope main.cpp:42: error: expected type-specifier before ‘QWebView’ main.cpp:42: error: expected `;' before ‘QWebView’ make: *** [main.o] Error 1 I have the web kit on my Fedora Core 10 machine: qt-4.5.3-9.fc10.i386 qt-devel-4.5.3-9.fc10.i386 Thanks all for any help

• Stopping/Removing an embedded player.

  - by Rajat

  Hi, I am working on a webpage where i have to include an embedded video.The video is hosted on some other domain.I am able to embed the video and autoplay once the web page is loaded.However i have a requirement where i have to remove the div displaying the video once it is played , and in place of the video i have to now display some text. The problem is i am able to do autoplay by the autostart variable in the embed tag...but how do i know that the video has ended.The hosting company only provides an embed tag and they donot have any player apis to use. One way (or rather a workaround) that i feel is to start a eventlistener in the background and see for the total time of the video and when that time is reached remove the content.But the problem is what if the user pauses the video, then also the div would be deleted. I am new to flash.Are there some standard variables or actions that we can pass as flashvars to a swf file to stop a running player or to know the state of the player (Note we are only getting an embed tag from the video hosting site so we donot own that code and they donot have much documenation to help me out with the code). Thanks for your help.

• Updating an application OTA

  - by Bostjan

  I'm developing an application that will be available from a website (market probably as well). The problem I'm having at the moment is how to handle the updates to the app. I know how to check the version against the current one and I know if I need to update it. Question is...how? Is there a way I can download an APK from the website and start the install process? The user will have to confirm of course, but I just want to be able to start it for him. At the moment I'm doing this: private void doUpgrade() { // TODO Auto-generated method stub Builder builder = new AlertDialog.Builder(this); builder.setTitle(getString(R.string.upgrade)); builder.setIcon(R.drawable.help); builder.setMessage(getString(R.string.needUpgrade)); builder.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Map<String, String> data = new HashMap<String, String>(); try { HttpResponse re = Registration.doPost("http://www.android-town.com/appRelease/AndroidTown.apk",data); int statusCode = re.getStatusLine().getStatusCode(); closeApp(); } catch (ClientProtocolException e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show(); closeApp(); } catch (IOException e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show(); closeApp(); } } }); builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub dialog.cancel(); closeApp(); } }); builder.show(); } But it doesn't really do anything...should I open a webView with the URL? A new runnable thread? Any other way? Please help :) Cheers
