  • How to fix emacs popup dialogs on Mac OS X??

    - by radekg
    Hello emacs gurus, I'm out of ideas here - my emacs crashes when popup dialog is opened. The x-popup-dialog function is probably to blame but I found no workaround to this. My Emacs version is 23.1.1 . Unfortunately some functionality of emacs calls this (e.x. customize asks whether it should save the changes) which causes the crash. Does anybody know how to fix it or disable it?

  • photoshop - How to show the cursor coordinate in selection and dropper

    - by q0987
    I am using Adobe Photoshop CS4 to edit a picture. The problems I have are that I don't know where I can see the mouse cursor coordinate while I move my mouse. Q1 For example, in Paint.Net, whenever I move mouse cursor, I can immediately see the feedback from bottom-right corner (x, y), how can I see such info in photoshop while I use eyedropper function? Q2 For example, when in crop mode, I drag-drop a rectangle but I cannot see the size of the created region of interest? Thank you

  • Does vim have the features to be used as an IDE?

    - by Kuroki Kaze
    I'm learning vim right now as I use it to quickly fix something in files on a server. Recently I've been thinking of switching from my IDE to vim, but I'm interested if all the features I need are in vim or if they can be added with plugins. I develop mainly in PHP and JavaScript. What I'm looking for is: Contextual help(point on function and see its arguments from oxygen docs) Code navigator(list of classes and functions in file to easily move between them)

  • How do I enable PHP apache_request_headers() or change PHP into an apache module

    - by inac
    PHP, WHM, and several other services are already installed on a CentOS x64 server I am trying to migrate data to. Many of my existing PHP scripts are dependent on PHP's apache_request_headers() function, which the current server's PHP configuration does not support. Apparently, compiling PHP as an Apache module is one solution, but are there other ways to enable this (without uninstalling PHP, reinstalling, etc., and all dependent services), perhaps as easy as modifying php.ini, somehow?

  • AIR:- Desktop Application related to Window Component (Need some work around)

    - by Mahesh Parate
    Create custom component which contains Combobox and Datagrid. Application conations two button 1) Same Window and 2) New Window. (Label of two button) When you click on “Same Window” button your custom component should get added dynamically in your application. And when you click on “New Window” button your custom component should get open in different window (it should get shifted from application and should appear in Window component). Issue faced:- Clicking on Combobox, list is not getting open as change event doesn’t get fired in Native Window as it looses reference from main application. Issue with DataGrid in Native window (AIR). • DataGridEvent.COLUMN_STRETCH event get affected if try to open datagrid in Native Window. • DataGridEvent get fired but takes long time or even stuck while column stretch Note: Application is an Desktop Application. Only one instance is created in Application for your custom component to preserve current state on your custom component it can be Style, data, or other subcomponent state of your custom component (as above mentioned 2 component are just sample).

  • Running an executable from PowerShell does not work with spaces in the path

    - by John Hartley
    From the PowerShell prompt: \Windows\system32\mspaint.exe will run Paint. So will Invoke-Expression -command "\Windows\system32\mspaint.exe" but if there is a space in the path PowerShell spits the dummy e.g. Invoke-Expression -command "\install\sub directory\test.bat" Which complains: The term '\install\sub' is not recognized as the name of a cmdlet, function, script file, or operable program. What am I missing?

  • Test of procedure is fine but when called from a menu gives uninitialized errors. C

    - by Delfic
    The language is portuguese, but I think you get the picture. My main calls only the menu function (the function in comment is the test which works). In the menu i introduce the option 1 which calls the same function. But there's something wrong. If i test it solely on the input: (1/1)x^2 //it reads the polinomyal (2/1) //reads the rational and returns 4 (you can guess what it does, calculates the value of an instace of x over a rational) My polinomyals are linear linked lists with a coeficient (rational) and a degree (int) int main () { menu_interactivo (); // instanciacao (); return 0; } void menu_interactivo(void) { int i; do{ printf("1.

  • How to implement Cocoa copyWithZone on derived object in MonoMac C#?

    - by Justin Aquadro
    I'm currently porting a small Winforms-based .NET application to use a native Mac front-end with MonoMac. The application has a TreeControl with icons and text, which does not exist out of the box in Cocoa. So far, I've ported almost all of the ImageAndTextCell code in Apple's DragNDrop example: https://developer.apple.com/library/mac/#samplecode/DragNDropOutlineView/Listings/ImageAndTextCell_m.html#//apple_ref/doc/uid/DTS40008831-ImageAndTextCell_m-DontLinkElementID_6, which is assigned to an NSOutlineView as a custom cell. It seems to be working almost perfectly, except that I have not figured out how to properly port the copyWithZone method. Unfortunately, this means the internal copies that NSOutlineView is making do not have the image field, and it leads to the images briefly vanishing during expand and collapse operations. The objective-c code in question is: - (id)copyWithZone:(NSZone *)zone { ImageAndTextCell *cell = (ImageAndTextCell *)[super copyWithZone:zone]; // The image ivar will be directly copied; we need to retain or copy it. cell->image = [image retain]; return cell; } The first line is what's tripping me up, as MonoMac does not expose a copyWithZone method, and I don't know how to otherwise call it. Update Based on current answers and additional research and testing, I've come up with a variety of models for copying an object. static List<ImageAndTextCell> _refPool = new List<ImageAndTextCell>(); // Method 1 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 2 [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); return cell; } [Export("dealloc")] public void Dealloc () { _refPool.Remove(this); this.Dispose(); } // Method 3 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 4 static IntPtr selRetain = Selector.GetHandle ("retain"); static IntPtr selRetainCount = Selector.GetHandle("retainCount"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone (IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell () { Title = Title, Image = Image, }; _refPool.Add (cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } public void PeriodicCleanup () { List<ImageAndTextCell> markedForDelete = new List<ImageAndTextCell> (); foreach (ImageAndTextCell cell in _refPool) { uint count = Messaging.UInt32_objc_msgSend (cell.Handle, selRetainCount); if (count == 1) markedForDelete.Add (cell); } foreach (ImageAndTextCell cell in markedForDelete) { _refPool.Remove (cell); cell.Dispose (); } } // Method 5 static IntPtr selCopyWithZone = Selector.GetHandle("copyWithZone:"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { IntPtr copyHandle = Messaging.IntPtr_objc_msgSendSuper_IntPtr(SuperHandle, selCopyWithZone, zone); ImageAndTextCell cell = new ImageAndTextCell(copyHandle) { Image = Image, }; _refPool.Add(cell); return cell; } Method 1: Increases the retain count of the unmanaged object. The unmanaged object will persist persist forever (I think? dealloc never called), and the managed object will be harvested early. Seems to be lose-lose all-around, but runs in practice. Method 2: Saves a reference of the managed object. The unmanaged object is left alone, and dealloc appears to be invoked at a reasonable time by the caller. At this point the managed object is released and disposed. This seems reasonable, but on the downside the base type's dealloc won't be run (I think?) Method 3: Increases the retain count and saves a reference. Unmanaged and managed objects leak forever. Method 4: Extends Method 3 by adding a cleanup function that is run periodically (e.g. during Init of each new ImageAndTextCell object). The cleanup function checks the retain counts of the stored objects. A retain count of 1 means the caller has released it, so we should as well. Should eliminate leaking in theory. Method 5: Attempt to invoke the copyWithZone method on the base type, and then construct a new ImageAndTextView object with the resulting handle. Seems to do the right thing (the base data is cloned). Internally, NSObject bumps the retain count on objects constructed like this, so we also use the PeriodicCleanup function to release these objects when they're no longer used. Based on the above, I believe Method 5 is the best approach since it should be the only one that results in a truly correct copy of the base type data, but I don't know if the approach is inherently dangerous (I am also making some assumptions about the underlying implementation of NSObject). So far nothing bad has happened "yet", but if anyone is able to vet my analysis then I would be more confident going forward.

  • 2Wire USB Network Adapter Not Working With Windows 7

    - by Andrew
    I installed Windows 7 on a separate drive, and everything works fine, but I can't get the above network adapter to work properly. It's displayed in Device Manager as a USB device, and I have the driver that makes it function in Vista, but when I run the Driver Wizard and direct it to directory where I have the Vista driver, it almost immediately says "Can't install driver." Is there any work around to this?

  • Looking for a free Morphing - Ageing program for Mac OS X.6.

    - by waszkiewicz
    Hi! I'm looking for a free morphing and/or ageing software for Mac OS X.6, not too hard to use, with the kind of Mac "one click" function, if you know what I mean. Cheap programs are also welcome, I paid for a Photoshop license, so why not another software... My goal is to be able to modify faces, make them look older or younger, add some piercing or other, funny stuff. Thanks for your tipps.
