  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • Example: Objective C method alongside a php method

    - by Nic Hubbard
    I am very used to javascript and php programing, and I just jumped into programing Objective C. After working with it for a few weeks, the methods still confused me, as to how it is passing params, and how the methods are named. Since I am used to php, I am used to seeing: function myFunc($param1, $param2, $param3, $param4) { return FALSE; } Could someone show me how this would be written in Objective C, so that I can get used to writing methods that have parameters?

  • Django : debugging templatetags

    - by interstar
    How on earth do people debug Django templatetags? I created one, based on a working example, my new tag looks the same to me as the existing one. But I just get a 'my_lib' is not a valid tag library: Could not load template library from django.templatetags.my_lib, No module named my_lib I know that this is probably because of something failing when defining the lib. But how do I see what's going on? What do you use to debug this situation?

  • UITableView not getting populated

    - by jayshree430
    Hi. I have a peculiar problem. I created a normal Objective c class called SampleTable. I then extended UITableView instead of NSObject. Then in the initWithFrame constructor i initialized the table. I also made a NSMutableArray object for the datasource. I also conformed UITableViewDelegate and UITableViewDatasource. I have overridden the necessary methods also. Now i made an object of this class in another class, and added the object as a subview. The tableView is getting drawn according to the CGRectMake() coordinates i gave to the initWithFrame constructor. But it is not getting populated with the data. I dnt know what the problem is . Can plz someone help me. SampleTable.h #import @interface SampleTable : UITableView { NSMutableArray *ItemArray; } @property (nonatomic,retain) NSMutableArray *ItemArray; -(NSMutableArray *) displayItemArray; @end SampleTable.m #import "SampleTable.h" @implementation SampleTable @synthesize ItemArray; -(id)initWithFrame:(CGRect)frm { [super initWithFrame:frm]; self.delegate=self; self.dataSource=self; [self reloadData]; return self; } -(NSMutableArray *) displayItemArray { if(ItemArray==nil) { ItemArray=[[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",nil]; } return ItemArray; } (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [ItemArray count]; } (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell= [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell==nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell autorelease]; } NSString *temp=[self.ItemArray objectAtIndex:indexPath.row]; cell.textLabel.text = temp; return cell; } (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"didselect"); } -(void) dealloc { [ItemArray release]; [super dealloc]; } @end

  • SharpZip escape filename

    - by mr.moses
    I'm using SharpZipLib to create a zip file with an html page and images. If the html file has a / in the name, it creates a folder (which messes up the image paths). Example: If the html file should be named Web/Design.html the zip file will contain a Web folder with a Design.html file in it. I've tried escaping / by replacing / with // or \/ but nothing has worked so far.

  • decrypt an encrypted value ?

    - by jim
    I have an old Paradox database (I can convert it to Access 2007) which contains more then 200,000 records. This database has two columns: the first one is named "Word" and the second one is named "Mean". It is a dictionary database and my client wants to convert this old database to ASP.NET and SQL. However, we don't know what key or method is used to encrypt or encode the "Mean" column which is in the Unicode format. The software itself has been written in Delphi 7 and we don't have the source code. My client only knows the credentials for logging in to database. The problem is decoding the Mean column. What I do have is the compiled windows application and the Paradox database. This software can decode the "Mean" column for each "Word" so the method and/or key is in its own compiled code(.exe) or one of the files in its directory. For example, we know that in the following row the "Zymurgy" exactly means "???? ??? ????? ?? ???? ????, ????? ?????" since the application translates it like that. Here is what the record looks like when I open the database in Access: Word Mean Zymurgy 5OBnGguKPdDAd7L2lnvd9Lnf1mdd2zDBQRxngsCuirK5h91sVmy0kpRcue/+ql9ORmP99Mn/QZ4= Therefore we're trying to discover how the value in the Mean column is converted to "???? ??? ????? ?? ???? ????, ????? ?????". I think the "Mean" column value in above row is encoded in Base64 string format, but decoding the Base64 string does not yet result in the expected text. The extensions for files in the win app directory are dll, CCC, DAT, exe (other than the main app file), SYS, FAM, MB, PX, TV, VAL. Any kind of help is appreciated. Additional information: guys! the creators are not that stupid to save the values only in encoded form. they're definitely encrypted them. so i guess we have to look for the key.

  • MKMapView Not Loading When Called on an NSThread?

    - by Chris
    I am creating a MKMapView in a method named "generateMap". From inside viewDidLoad, this works: [self generateMap]; but this causes the map to quickly load and then disappear, leaving only the blank grey grid: [NSThread detachNewThreadSelector:@selector(spinTheSpinner) toTarget:self withObject:nil]; Any ideas why this might be happening when I call the method through a thread?

  • Naming lossless more appropriate

    - by LarsOn
    Starting just discussing the naming first ignoring tech details, lossless is a negative and double negative word for one good reason should get named more appropriate: Lossless also matches nothing. When naming like all intact or likewise matches something in a manner more physical like sounds are. Then more technically stated that a copy might contain more information than the original. Does method as such have a name, if so what do I refer to, can we name it if you please or just discuss related handling.

    Can a compound key be set as a primary key to another table? For instance i have the tables: Books -with Primary Key:Product_ID Client -with Primary key: Client_ID Clients_Books -with Compound Primary Key:Product_Id and Client_ID I want to set this compound Primary key from Clients_Books as a Primary Key to another table named: Order_Details. But I don't want to use the Product_ID and the Client_ID from the Books, Clients tables. Does this make sense? All opinions more than welcome.

  • Scrapy domain_name for spider

    - by Zeynel
    From the Scrapy tutorial: domain_name: identifies the Spider. It must be unique, that is, you can’t set the same domain name for different Spiders. Does this mean that domain_name must be a valid domain name, like domain_name = 'example.com' Or can I name domain_name = 'ex1' The problem is I had a spider that worked with domain name domain_name = 'whitecase.com' Now I created a new spider as an instance of CrawlSpider and named it domain_name = 'wc2' but I am getting the error "could not find spider for domain "wc2""

  • XML to be validated against multiple xsd schemas

    - by Michael Rusch
    I'm writing the xsd and the code to validate, so I have great control here. I would like to have an upload facility that adds stuff to my application based on an xml file. One part of the xml file should be validated against different schemas based on one of the values in the other part of it. Here's an example to illustrate: <foo> <name>Harold</name> <bar>Alpha</bar> <baz>Mercury</baz> <!-- ... more general info that applies to all foos ... --> <bar-config> <!-- the content here is specific to the bar named "Alpha" --> </bar-config> <baz-config> <!-- the content here is specific to the baz named "Mercury" --> </baz> </foo> In this case, there is some controlled vocabulary for the content of <bar>, and I can handle that part just fine. Then, based on the bar value, the appropriate xml schema should be used to validate the content of bar-config. Similarly for baz and baz-config. The code doing the parsing/validation is written in Java. Not sure how language-dependent the solution will be. Ideally, the solution would permit the xml author to declare the appropriate schema locations and what-not so that s/he could get the xml validated on the fly in a sufficiently smart editor. Also, the possible values for <bar> and <baz> are orthogonal, so I don't want to do this by extension for every possible bar/baz combo. What I mean is, if there are 24 possible bar values/schemas and 8 possible baz values/schemas, I want to be able to write 1 + 24 + 8 = 33 total schemas, instead of 1 * 24 * 8 = 192 total schemas. Also, I'd prefer to NOT break out the bar-config and baz-config into separate xml files if possible. I realize that might make all the problems much easier, as each xml file would have a single schema, but I'm trying to see if there is a good single-xml-file solution.

  • C++ Pointers, objects, etc

    - by Zeee
    It may be a bit confusing, but... Let's say I have a vector type in a class to store objects, something like vector, and I have methods on my class that will later return Operators from this vector. Now if any of my methods receives an Operator, will I have any trouble to insert it directly into the vector? Or should I use the copy constructor to create a new Operator and put this new one on the vector?

  • StructureMap Autowiring with two different instances of the same interface

    - by Lambda
    For the last two days, i tried my best to learn something about StructureMap, using an old project of mine as an concrete implementation example. I tried to simplify my question as much as possible. While i will post my examples in vb.net, answers with examples in C# are also okay. The project includes an interfaces called IDatabase which connects itself to a Database. The important part looks like this. Public Interface IDatabase Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean ReadOnly Property ConnectionOpen As Boolean [... more functions...] End Interface Public Class MSSQLConnection Implements IDatabase Public Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean Implements IDatabase.Connect [... Implementation ...] End Function [... more implementations...] End Class ConnectionSettings is a structure that has all the information needed to connect to a Database. I want to open the Database Connection once and use it for every single connection in the project, so i register a instance in the ObjectFactory. dim foo = ObjectFactory.GetInstance(Of MSSQLConnection)() dim bar as ConnectionSettings foo.connect(bar) ObjectFactory.Configure(Sub(x) x.For(Of IDatabase).Use(foo)) Up until this part, everything works like a charm. Now, i get to a point where i hav e classes that need an additional instance of IDatabase because they connect to a second database. Public Class ExampleClass Public Sub New(ByVal SameOldDatabase as IDatabase, ByVal NewDatabase as IDatabase) [...] Magic happens here [...] End Sub End Class I want this second IDatabase to behave much like the first one. I want it to use a concrete, single instance and want to connect it to a different database invoking Connect with a different ConnectionSettings. The problem is: While i'm pretty sure it's somewhow possible, (my initial idea was registering ExampleClass with alternative constructor arguments), i actually want to do it without registering ExampleClass. This probably involves more configuration, but i have no idea how to do it. So, basically, it comes down to this question: How do i configurate the ObjectFactory in a way that the autowiring always invokes the constructor with object Database1 for the first IDatabase parameter and object Database2 for the second one (if there is one?)

What does that mean?

  • What should I do or don't do to avoid Delphi "push dword" bug.

    - by Maksee
    I found that Delphi 5 generates invalid assembly code in specific cases. I can't understand in what cases in general. The example below produces access violation since a very strange optimization occurs. For a byte in a record or array Delphi generates push dword [...], pop ebx, mov .., bl that works correctly if there are data after this byte (we need at least three to push dword correctly), but fails if the data is inaccessible. I emulated the strict boundaries here with win32 Virtual* functions Specifically the error occurs when the last byte from the block accessed inside FeedBytesToClass procedure. And if I try to change something like using data array instead of object property of remove actionFlag variable, Delphi generates correct assembly instructions. const BlockSize = 4096; type TSomeClass = class private fBytes: PByteArray; public property Bytes: PByteArray read fBytes; constructor Create; destructor Destroy;override; end; constructor TSomeClass.Create; begin inherited Create; GetMem(fBytes, BlockSize); end; destructor TSomeClass.Destroy; begin FreeMem(fBytes); inherited; end; procedure FeedBytesToClass(SrcDataBytes: PByteArray; Count: integer); var j: integer; Ofs: integer; actionFlag: boolean; AClass: TSomeClass; begin AClass:=TSomeClass.Create; try actionFlag:=true; for j:=0 to Count-1 do begin Ofs:=j; if actionFlag then begin AClass.Bytes[Ofs]:=SrcDataBytes[j]; end; end; finally AClass.Free; end; end; procedure TForm31.Button1Click(Sender: TObject); var SrcDataBytes: PByteArray; begin SrcDataBytes:=VirtualAlloc(Nil, BlockSize, MEM_COMMIT, PAGE_READWRITE); try if VirtualLock(SrcDataBytes, BlockSize) then try FeedBytesToClass(SrcDataBytes, BlockSize); finally VirtualUnLock(SrcDataBytes, BlockSize); end; finally VirtualFree(SrcDataBytes, MEM_DECOMMIT, BlockSize); end; end; Initially the error occured when I used access to RGB data of bitmap bits, but the code there is too complex so I narrowed it to this fragment. So the question is what is here so specific that makes Delphi produce push,pop,mov optimization. I need to know this in order to avoid such side effects in general.

  • Singleton: How should it be used

    - by Loki Astari
    Edit: From another question I provided an answer that has links to a lot of questions/answers about singeltons: More info about singletons here: So I have read the thread Singletons: good design or a crutch? And the argument still rages. I see Singletons as a Design Pattern (good and bad). The problem with Singleton is not the Pattern but rather the users (sorry everybody). Everybody and their father thinks they can implement one correctly (and from the many interviews I have done, most people can't). Also because everybody thinks they can implement a correct Singleton they abuse the Pattern and use it in situations that are not appropriate (replacing global variables with Singletons!). So the main questions that need to be answered are: When should you use a Singleton How do you implement a Singleton correctly My hope for this article is that we can collect together in a single place (rather than having to google and search multiple sites) an authoritative source of when (and then how) to use a Singleton correctly. Also appropriate would be a list of Anti-Usages and common bad implementations explaining why they fail to work and for good implementations their weaknesses. So get the ball rolling: I will hold my hand up and say this is what I use but probably has problems. I like "Scott Myers" handling of the subject in his books "Effective C++" Good Situations to use Singletons (not many): Logging frameworks Thread recycling pools /* * C++ Singleton * Limitation: Single Threaded Design * See: http://www.aristeia.com/Papers/DDJ_Jul_Aug_2004_revised.pdf * For problems associated with locking in multi threaded applications * * Limitation: * If you use this Singleton (A) within a destructor of another Singleton (B) * This Singleton (A) must be fully constructed before the constructor of (B) * is called. */ class MySingleton { private: // Private Constructor MySingleton(); // Stop the compiler generating methods of copy the object MySingleton(MySingleton const& copy); // Not Implemented MySingleton& operator=(MySingleton const& copy); // Not Implemented public: static MySingleton& getInstance() { // The only instance // Guaranteed to be lazy initialized // Guaranteed that it will be destroyed correctly static MySingleton instance; return instance; } }; OK. Lets get some criticism and other implementations together. :-)
