  • Excel 2007 - "The macro may not be available in this workbook" Error

    - by Psycho Bob
    We use an Excel sheet that has been protected to prevent modification of it from end users. All in all they are only able to edit certain tabs to add information that will then be used to generate information on other tabs using equations and such. On the tab with the equations, a button is present called "Prep for Internal Hard Copy Print." This button runs a macro that selects the information on the tab, unprotects it, then sends a print job to the user's default printer that contains the unprotected content. Normally this works like a champ. This time around, however, the macro is throwing the following error: Cannot run the macro "FILENAME.xlsx'!MacroName'. The macro may not be available in this workbook or all macros may be disabled. As far as I can tell, the macros are still present within the workbook. This sheet is normally a .xlsm though the user saved it with a different filename as a .xlsx. Also, the macros appear only as MacroName in the .xlsm file and not "FILENAME.xlsx'!MacroName' as it does in the .xlsx. Finally, when I open the .xlsm it asks if I want to enable the macro content while the .xlsx does not prompt for this. Can anyone tell me what's going on with this sheet or know of a way that I can get the macros working in the .xlsx without having to start over with a different sheet?

  • How can I create/update an XML node that may or may not exist?

    - by ScottBai
    Is there a method available (i.e. without me creating my own recursive method), for a given xpath (or other method of identifying the hierarchical position) to create/update an XML node, where the node would be created if it does not exist? This would need to create the parent node if it does not exist as well. I do have an XSD which includes all possible nodes. i.e. Before: <employee> <name>John Smith</name> </employee> Would like to call something like this: CoolXmlUpdateMethod("/employee/address/city", "Los Angeles"); After: <employee> <name>John Smith</name> <address> <city>Los Angeles</city> </address> </employee> Or even a method to create a node, given an xpath, wherein it will recursively create the parent node(s) if they do not exist? As far as the application (if it matters), this is taking an existing XML doc that contains only populated nodes, and adding data to it from another system. The new data may or may not already have values populated in the source XML. Surely this is not an uncommon scenario?

  • Vaadin - GWT error "module xxx may need to be recompiled

    - by John Leonard
    I'm ramping up on Vaadin and I'm getting this javascript alert whenever I try and run the demo apps. GWT module 'com.vaadin.terminal.gwt.DefaultWidgetSet' may need to be recompiled I've tried cleaning the project to no avail. As I said, I'm ramping up so I'm sure there's some simple step I'm missing or a concept I haven't grasped.

  • Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.iAndAp

    - by Nicsoft
    Hello, I'm having this annoyning problem giving this message in the console: Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.iAndApp.BlockPop. When trying to Build and Run, the application builds fine. The simulator starts but doesn't start the application. However, it manages to do something since the icon for the app is installed in the simulator. I have been searching to find the answer and tried a couple of things, none that worked. This happens for both new and old projects. I.e. when I create a new project I will receive the same error message. I've tried several projects of which all get the same error, so it's not related to the code (and successful builds proves it). Among other things I have updated to xCode 3.2.2. in order to try to solve the problem. Using Mac OSX 10.6.3.

  • Method may fail to close stream on exception

    - by 01
    I get the critical error with finbugs The method creates an IO stream object, does not assign it to any fields, pass it to other methods, or return it, and does not appear to close it on all possible exception paths out of the method. This may result in a file descriptor leak. It is generally a good idea to use a finally block to ensure that streams are closed. try { ... stdError = new BufferedReader(new InputStreamReader(p.getErrorStream())); ... } catch (IOException e) { throw new RuntimeException(e); } finally { try { if (stdInput != null) { stdInput.close(); } if (stdError != null) { stdError.close(); } } catch (IOException e) { throw new RuntimeException(e); } } do i need to close also InputStreamReader or p.getErrorStream(it returns InputStream) ??

  • Clearing "may not respond" warnings for UIView and UIViewController

    - by user284681
    In an iPad app, I'm using a custom subclass of UIView with UIViewController. Here's the view header: @interface pdfView : UIView { CGPDFDocumentRef doc; } -(void)setDoc:(CGPDFDocumentRef)newDoc; @end And here's the controller header: @interface iPadPDFTestViewController : UIViewController { CGPDFDocumentRef doc; } - (void)loadPDF; @end Part of the controller implementation: - (void)viewDidLoad { [super viewDidLoad]; [self loadPDF]; [self.view setDoc:doc]; } In Interface Builder, I've set the view object to use the class pdfView. At compilation, [self.view setDoc:doc]; gives the warning "'UIView' may not respond to '--setDoc'." I'm guessing that this warning appears because the compiler thinks it's looking at UIView (which does not implement the setDoc method) instead of pdfView. But why does it think that? And how can I tell it what class it's really looking at, so as to clear the warning?

  • Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

    - by brad
    I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?

  • NSNotification center may not respond to -object ?

    - by blackkettle
    Hi, I'm trying to make simple use of the NSNotification center inside my iPhone application, but I seem to be doing something wrong in this case. I was under the impression that it was possible to retrieve an object associated with a particular message, or at least a reference to the object, but using the following example code I'm getting a warning, "NSNotification center may not respond to -object" - (void)addNewBookmark:(NSNotificationCenter *)notification { Bookmark *newBookMark = (Bookmark *)[notification object]; //Do some stuff with the bookmark object } Indeed, when I compile and run the code, basically nothing I try to do with the contents of the object actually gets carried out - it's simply ignored. The post code is as follows, - (IBAction)save:(id) sender{ //Sending the message with the related object [[NSNotificationCenter defaultCenter] postNotificationName:@"addNewBookmark" object:bookmark]; } and the bookmark object itself is just a dictionary. I also tried using the "userInfo" argument and passing the bookmark object through that, but the result was the same. How should I be doing this? What am I doing wrong?

  • Efficient JSON encoding for data that may be binary, but is often text

    - by Evgeny
    I need to send a JSON packet across the wire with the contents of an arbitrary file. This may be a binary file (like a ZIP file), but most often it will be plain ASCII text. I'm currently using base64 encoding, which handles all files, but it increases the size of the data significantly - even if the file is ASCII to begin with. Is there a more efficient way I can encode the data, other than manually checking for any non-ASCII characters and then deciding whether or not to base64-encode it? I'm currently writing this in Python, but will probably need to do the same in Java, C# and C++, so an easily portable solution would be preferable.

  • Scala: "Parameter type in structural refinement may not refer to an abstract type defined outside th

    - by raichoo
    Hi, I'm having a problem with scala generics. While the first function I defined here seems to be perfectly ok, the compiler complains about the second definition with: error: Parameter type in structural refinement may not refer to an abstract type defined outside that refinement def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { ^ What am I doing wrong here? trait Lifter[C[_]] { implicit def liftToMonad[A](c: C[A]) = new { def >>=[B](f: A => C[B])(implicit m: Monad[C]): C[B] = { m >>= (c, f) } def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { m >> a } } } IMPORTANT: This is NOT a question about Monads, it's a question about scala polymorphism in general.

  • Warning of "Control may reach end of non-void function"

    - by Cloud_cal
    I ran a C++ program in Xcode, and encountered a warning of "Control may reach end of non-void function". Here is the code: Node* search(Node* head, int x) { if(!head) return NULL; else if(x == head->key) return head; else if(x < head->key) search(head->lchild, x); else search(head->rchild, x); } I got the same warning when compiling it in Linux, but got the correct result. But in Xcode, the result was wrong. By the way, I got the correct answer and no warning in Visual Studio.

  • Why does ruby-debug say 'Saved frames may be incomplete'

    From time-to-time I get this when a breakpoint is triggered. It looks like stack frames aren't getting saved so I can't step back through the call stack - a real pain.

  • xcode may not respond to warning

    - by Frames84
    Hi all, Can't seem to get rid of a warning. The warning is: 'UIImage' may not respond to '-scaleToSize' above the @implmentation MyViewController I have this @implementation: @implementation UIImage (scale) -(UIImage*)scaleToSize:(CGSize)size { UIGraphicsBeginImageContext(size); [self drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* scaledImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return scaledImage; } @end Then I have MyViewController implementation @implementation TodayNewsTableViewController @synthesize dataList; ...... - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MainNewsCellIdentifier = @"MainNewsCellIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: MainNewsCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier: MainNewsCellIdentifier] autorelease]; } NSUInteger row = [indexPath row]; NSDictionary *stream = (NSDictionary *) [dataList objectAtIndex:row]; NSString *title = [stream valueForKey:@"title"]; if( !

  • How I May Have Taken A Wrong Path in Programming

    - by Ygam
    I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

  • Designing model/database for distance between any two locations (that may change)

    - by Yo Ludke
    We should create a web app which has a number of events each with a location (created as user-generated content, so the number of events will be increasingly large). The distance between any events should be available, for example to determine the top 5 closest events and such things. Users may change the locations of events. How should one design the database/model for this (in a scalable way)? I was thinking of doing it with a "distance table" (like so http://www.deutschland-tourist.info/images/entfernungstabelle.gif). Then every time, if a location changes, one row and one column have to be recalculated (this should be done with a delayed job, because it is not important to have the changes instantly). Possible problems in Scaling: Database to large (n² items for n events), too much calculation to be done. For example we should see if this is okay for 10.000 users. If each has created just one event, then this would be 100 million integers... Do you think this would be a good way to do it efficiently? How could one realize such a distance table with an rails model? Is it possible with a SQL databse? Would you start other approaches?

  • May volatile be in user defined types to help writing thread-safe code

    - by David Rodríguez - dribeas
    I know, it has been made quite clear in a couple of questions/answers before, that volatile is related to the visible state of the c++ memory model and not to multithreading. On the other hand, this article by Alexandrescu uses the volatile keyword not as a runtime feature but rather as a compile time check to force the compiler into failing to accept code that could be not thread safe. In the article the keyword is used more like a required_thread_safety tag than the actual intended use of volatile. Is this (ab)use of volatile appropriate? What possible gotchas may be hidden in the approach? The first thing that comes to mind is added confusion: volatile is not related to thread safety, but by lack of a better tool I could accept it. Basic simplification of the article: If you declare a variable volatile, only volatile member methods can be called on it, so the compiler will block calling code to other methods. Declaring an std::vector instance as volatile will block all uses of the class. Adding a wrapper in the shape of a locking pointer that performs a const_cast to release the volatile requirement, any access through the locking pointer will be allowed. Stealing from the article: template <typename T> class LockingPtr { public: // Constructors/destructors LockingPtr(volatile T& obj, Mutex& mtx) : pObj_(const_cast<T*>(&obj)), pMtx_(&mtx) { mtx.Lock(); } ~LockingPtr() { pMtx_->Unlock(); } // Pointer behavior T& operator*() { return *pObj_; } T* operator->() { return pObj_; } private: T* pObj_; Mutex* pMtx_; LockingPtr(const LockingPtr&); LockingPtr& operator=(const LockingPtr&); }; class SyncBuf { public: void Thread1() { LockingPtr<BufT> lpBuf(buffer_, mtx_); BufT::iterator i = lpBuf->begin(); for (; i != lpBuf->end(); ++i) { // ... use *i ... } } void Thread2(); private: typedef vector<char> BufT; volatile BufT buffer_; Mutex mtx_; // controls access to buffer_ };
