  • Error occure while validating form input using JQUERY in Firebug

    - by Param-Ganak
    Hello Friends, I have written a custom validation code in JQUERY. which is working fine. I have a login form which have two fields i.e. userid and password. I have written a custom JQUERY code for client side validation for these fields. This custom JQUERY code is working fine and gives me proper error messages as per the situation. But the problem with this code is that when I enter the invalid data in any or both field and press submit button of form then it displays the proper error message but at the same time when I checked it in Firebug it displays following error message when submit button of the form is clicked validate is not defined function onclick(event) { javascript: return validate(); }(click clientX=473, clientY=273) So please tell me where is I am wrong in my Jquery code. Thank You!

  • How can I get type information at runtime from a DMP file in a Windbg extension?

    - by pj4533
    This is related to my previous question, regarding pulling objects from a dmp file. As I mentioned in the previous question, I can successfully pull object out of the dmp file by creating wrapper 'remote' objects. I have implemented several of these so far, and it seems to be working well. However I have run into a snag. In one case, a pointer is stored in a class, say of type 'SomeBaseClass', but that object is actually of the type 'SomeDerivedClass' which derives from 'SomeBaseClass'. For example it would be something like this: MyApplication!SomeObject +0x000 field1 : Ptr32 SomeBaseClass +0x004 field2 : Ptr32 SomeOtherClass +0x008 field3 : Ptr32 SomeOtherClass I need someway to find out what the ACTUAL type of 'field1' is. To be more specific, using example addresses: MyApplication!SomeObject +0x000 field1 : 0cae2e24 SomeBaseClass +0x004 field2 : 0x262c8d3c SomeOtherClass +0x008 field3 : 0x262c8d3c SomeOtherClass 0:000> dt SomeBaseClass 0cae2e24 MyApplication!SomeBaseClass +0x000 __VFN_table : 0x02de89e4 +0x038 basefield1 : (null) +0x03c basefield2 : 3 0:000> dt SomeDerivedClass 0cae2e24 MyApplication!SomeDerivedClass +0x000 __VFN_table : 0x02de89e4 +0x038 basefield1 : (null) +0x03c basefield2 : 3 +0x040 derivedfield1 : 357 +0x044 derivedfield2 : timecode_t When I am in WinDbg, I can do this: dt 0x02de89e4 And it will show the type: 0:000> dt 0x02de89e4 SomeDerivedClass::`vftable' Symbol not found. But how do get that inside an extension? Can I use SearchMemory() to look for 'SomeDerivedClass::`vftable'? If you follow my other question, I need this type information so I know what type of wrapper remote classes to create. I figure it might end up being some sort of case-statement, where I have to match a string to a type? I am ok with that, but I still don't know where I can get that string that represents the type of the object in question (ie SomeObject-field1 in the above example).

  • Is there performance to be gained by moving storage allocation local to a member function to its cla

    - by neuviemeporte
    Suppose I have the following C++ class: class Foo { double bar(double sth); }; double Foo::bar(double sth) { double a,b,c,d,e,f a = b = c = d = e = f = 0; /* do stuff with a..f and sth */ } The function bar() will be called millions of times in a loop. Obviously, each time it's called, the variables a..f have to be allocated. Will I gain any performance by making the variables a..f members of the Foo class and just initializing them at the function's point of entry? On the other hand, the values of a..f will be dereferenced through this-, so I'm wondering if it isn't actually a possible performance degradation. Is there any overhead to accessing a value through a pointer? Thanks!

  • Objective-c garbage collection

    - by Chris
    If garbage collection is not required: - (void) awakeFromNib{ //Create the NSStatusBar and set its length statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength] retain]; ... Do I have to release that? And if I do, would that be in a finalize method or dealloc method? If garbage collection is required, then is the retain call above ignored automatically?

  • Getting the front buffer into a gfx mem surface (Dx9)

    - by lapin
    I'm using DirectX 9 to acquire the frontbuffer. There are a couple of ways I know of to get at the front buffer: GetRenderTargetData() GetFrontBufferData() The MSDN page on both of these API calls state that the data is copied from device memory to system memory. I'd like to copy the front buffer surface directly to another graphics memory surface, as I have other manipulations to perform on the acquired surface before returning it to system memory. I'm creating a D3DUSAGE_DYNAMIC texture (gfx mem texture) and calling GetFrontBufferData() to write the front buffer to my textures surface0. Is this valid? Will the operation remain in gfx memory, or will it need to move to system memory and then back to graphics memory? If this is the case, is what I'm trying to achieve possible?

  • App crashes every second time a tableview row is selected in navigation controller setup

    - by Thaurin
    Disclaimer first: I'm pretty new to Objective-C and the retain model. I've been developing in a garbage collected .NET environment for the last five years, so I've been spoiled. I'm still learning. I'm having my iPhone app crash with EXC_BAD_ACCESS. It happens in a navigtation controller/tableview setup. When I select a row the first time, no problems. It switches in the child controller without problems. I go back and select the same row again. Program then proceeds to crash. Every other row works fine, but every second time a row is accessed, it's a crash. I've pinpointed the location where this happens. The child controller (which is a class that I reuse for every row of the same type) that's being switched into has an array of NSString's representing the rows that will be displayed. I set it before pushing the child viewcontroller. It's there where this apparently happens. I'm having a hard time debugging this problem, still wrestling with xcode and all. I fear there may be some vital information missing here, but maybe there is something you recognize here.

  • Trying to catch integrity error with sqlaclhemey

    - by Lostsoul
    I'm having problems with trying to catch a error. I'm using pyramid/sqlalchemy and made a sign up form with email as the primary key. The problem is when a duplicate email is entered it raises a IntegrityError, so I'm trying to catch that error and provide a message but no matter what I do I can't catch it(the error keeps appearing). try: new_user = Users(email, firstname, lastname, password) DBSession.add(new_user) return HTTPFound(location = request.route_url('new')) except IntegrityError: message1 = "Yikes! Your email already exists in our system. Did you forget your password?" I get the same message when I tried except exc.SQLAlchemyError (although I want to catch specific errors and not a blanket catch all). Is there something wrong with my python syntax? or is there something I need to do special in sqlalchemy to catch it?

  • calling std::cout.rdbuf() produces syntax error

    - by Mikepote
    Maybe I missed something, but I cant figure out why Visual Studio 2008 isn't seeing the rdbuf() procedure. Here is my code: 16. #include "DebugBuffer/BufferedStringBuf.h" 17. 18. BufferedStringBuf debug_buffer(256); 19. std::cout.rdbuf(&debug_buffer); The BufferedStringBuf class is from this page: http://www.devmaster.net/forums/showthread.php?t=7037 Which produces the following error: ...src\main.cpp(19) : error C2143: syntax error : missing ';' before '.' All I want to do is redirect std::cout to the Visual Studio Output window using OutputDebugString()..

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • Compile error on action for iPhone app: "error:expected ')' before ';' token"

    - by Jamis Charles
    I'm working through the tutorials in the "Beginning iPhone Development" book. I'm on chapter 4 and I'm getting the following compile error on the "if (segment == kShowSegmentIndex)" line: error:expected ')' before ';' token Here's my code: - (IBAction)toggleShowHide:(id)sender{ UISegmentedControl *segmentedControl = (UISegmentedControl *)sender; NSInteger segment = segmentedControl.selectedSegmentIndex; if (segment == kShowSegmentIndex) [switchView setHidden:NO]; else [switchView setHidden:YES]; } I've compared it with the code in the book several times and have retyped it. Sounds like this error is caused by improper brace placement. Any thoughts?

  • Could not load file or assembly error even when reference has been removed

    - by twal
    Could not load file or assembly 'Payflow_dotNET_2.0' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) I tried to reference the payflow SDK and got this error.But I am no longer trying to reference it. I have removed all references to this dll. and Now I am just trying to get the project to start in VS but I still get this error. I am not trying to add the dll anymore.If i have removed the reference to this, why am I still getting this error? How can I remove anything else that may still be causing my program to look for this file? Thanks!

  • Can't process UIImage from UIImagePickerController and app crashes..

    - by eimaikala
    Hello guys, I am new to iPhone sdk and can't figure out why my application crashes. In the .h I have: UIImage *myimage; //so as it can be used as global -(IBAction) save; @property (nonatomic, retain) UIImage *myimage; In the .m I have: @synthesize myimage; - (void)viewDidLoad { self.imgPicker = [[UIImagePickerController alloc] init]; self.imgPicker.allowsImageEditing = YES; self.imgPicker.delegate = self; self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { myimage = [[info objectForKey:UIImagePickerControllerOriginalImage]retain]; [picker dismissModalViewControllerAnimated:YES]; } -(IBAction) process{ myimage=[self process:myimage var2:Val2 var3:Val3 var4:Val4]; UIImageWriteToSavedPhotosAlbum(myimage, nil, nil, nil); [myimage release]; } When the button process is clicked, the application crashes and really I have no idea why this happens. When i change it to: -(IBAction) process{ myimage =[UIImage imageNamed:@"im1.jpg"]; myimage=[self process:myimage var2:Val2 var3:Val3 var4:Val4]; UIImageWriteToSavedPhotosAlbum(myimage, nil, nil, nil); [myimage release]; } the process button works perfectly... Any help would be appreciated. Thanks in advance

  • compile error: The import xxxx cannot be resolved

    - by Zachary
    I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

  • Retain cycle on `self` with blocks

    - by Jonathan Sterling
    I'm afraid this question is pretty basic, but I think it's relevant to a lot of Objective-C programmers who are getting into blocks. What I've heard is that since blocks capture local variables referenced within them as const copies, using self within a block can result in a retain cycle, should that block be copied. So, we are supposed to use __block to force the block to deal directly with self instead of having it copied. __block typeof(self) bself = self; [someObject messageWithBlock:^{ [bself doSomething]; }]; instead of just [someObject messageWithBlock:^{ [self doSomething]; }]; What I'd like to know is the following: if this is true, is there a way that I can avoid the ugliness (aside from using GC)?

  • Why does php show error for my SQL query

    - by ZincX
    UPDATE: My mistake - I made a typo. Nevermind this question. I'm using php to update a mysql database. The resultant query I'm using when i print it out on my webpage before executing is as follows: INSERT INTO perch2_content_items (itemOrder, regionID, pageID, itemRev, itemID, itemJSON, itemSearch ) SELECT MAX(itemOrder)+1, 105, 81, 11, 118, 'json', 'search' FROM perch2_content_items WHERE regionID=105 When I copy and paste this query directly into the phpmyadmin SQL interface, it works fine. The table gets updated. However, when I try to execute it using my php code as follows, it throws an error. $insertToPerch = "INSERT INTO perch2_content_items (itemOrder, regionID, pageID, itemRev, itemID, itemJSON, itemSearch ) SELECT MAX(itemOrder)+1, $regionID, $pageID, $regionRev, $newItemID, 'json', 'search' FROM perch2_content_items WHERE regionID=$regionID"; mysql_query(insertToPerch) or die(mysql_error()); The error I'm getting is: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'insertToPerch' at line 1 Can anybody help me figure out why it is failing.

  • Removing DOM event handlers in long-running browser session

    - by Chris Beck
    I have a browser interface with a ul#contacts list on the left and div#contact property panel (email, phone) on the right. Click a contact in the list and my app makes an XHR request to get the contact property HTML fragment and update div#contact.innerHTML. Each contact fragment has an "Edit Contact" link. With JS, I progressively upgrade that link with an event listener that performs an XHR request to replace the static property panel with an in-place edit form. This can happen many times during a single browser session. How should I clean up my "Edit Contact" event listener? Do I need to remove it manually before the form overwrites the property panel? Or is the event listener cleaned up automatically when the contents of div#contact (and the node that I'm listening on) is overwritten? FWIW, I still consider IE6 to be part of my target market.

  • Excel vba: error hiding calculated field in Pivot table

    - by Patrick Honorez
    I have written several Subs to show/hide fields in a PivotTable. Now I am trying to do the same with a calculated field, but I get an error when hiding it. I took my code from the recorder and the recorder's code also halts on the last line. I googled the error message, without serious result. Sub PrRemove() 'remove PR Dim pt As PivotTable Set pt = ActiveSheet.PivotTables("MyPivot") pt.PivotFields("MyField").Orientation = xlHidden '<- here is the error End Sub The same code works fine if MyField is a normal field (not a calculated one). I am using Excel 2007 with SP2. Any clue ?

  • VS 2008 linking error

    I'm using Visual Studio 2008 C++ and working on a dll project.

  • Container for database-like searches

    - by Milan Babuškov
    I'm looking for some STL, boost, or similar container to use the same way indexes are used in databases to search for record using a query like this: select * from table1 where field1 starting with 'X'; or select * from table1 where field1 like 'X%'; I thought about using std::map, but I cannot because I need to search for fields that "start with" some text, and not those that are "equal to". I could create a sorted vector or list and use binary search (breaking the set in 2 in each step by reading the element in the middle and seeing if it's more or less than 'X'), but I wonder if there is some ready-made container I could use without reinventing the wheel?

  • Using CreateFileMapping between to programs - C

    - by Jamie Keeling
    Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

  • C++ -malign-double compiler flag

    - by Martin
    I need some help on compiler flags in c++. I'm using a library that is a port to linux from windows, that has to be compiled with the -malign-double flag, "for Win32 compatibility". It's my understanding that this mean I absolutely have to compile my own code with this flag as well? How about other .so shared libraries, do they have be recompiled with this flag as well? If so, is there any way around this? I'm a linux newbie (and c++), so even though I tried to recompile all the libraries I'm using for my project, it was just too complicated to recursively find the source for all the libraries and the libraries they're dependent on, and recompile everything.
