  • UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

    - by Jesse Grosjean
    Edit Reposting... I accidentally marked my previous question as "commuity wiki" and didn't realize that answers to wiki posts don't generate reputation. I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the UIAlertView the cut/copy/paste popup menu will show in UITextField that's been added to the UIAlertView. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again next time I show the UIAlertView (new instance) unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

  • Trying to exclude certain extensions doing a recursive copy (MSBuild)

    - by Kragen
    I'm trying to use MSBuild to read in a list of files from a text file, and then perform a recursive copy, copying the contents of those directories files to some staging area, while excluding certain extensions (e.g. .tmp files) I've managed to do most of the above quite easily using CreateItem and the MSBuild copy task, whatever I do the CreateItem task just ignores my Exclude parameter: <PropertyGroup> <RootFolder>c:\temp</RootFolder> <ExcludeFilter>*.tmp</ExcludeFilter> <StagingDirectory>staging</StagingDirectory> </PropertyGroup> <ItemGroup> <InputFile Include="MyFile.txt" /> </ItemGroup> <Target Name="Build"> <ReadLinesFromFile File="@(InputFile)"> <Output ItemName="AllFolders" TaskParameter="Lines" /> </ReadLinesFromFile> <CreateItem Include="$(RootFolder)\%(AllFolders.RelativeDir)**" Exclude="$(ExcludeFilter)"> <Output ItemName="AllFiles" TaskParameter="Include" /> </CreateItem> <Copy SourceFiles="@(AllFiles)" DestinationFolder="$(StagingDirectory)\%(RecursiveDir)" Example contents of 'MyFile.txt': somedirectory\ someotherdirectory\ (I.e. the paths are relative to $(RootFolder) - mention this because I read somewhere that it might be relevant) I've tried loads of different combinations of Exclude filters, but I never seem to be able to get it to correctly exclude my .tmp files - is there any way of doing this with MSBuild without resorting to xcopy?

  • Copy folders when copying list items from source to destination

    - by iHeartDucks
    Hi, This is my code to copy files in a list from source to destination. Using the code below I am only able to copy files but not folders. Any ideas on how can I copy the folders and the files within those folders? using (SPSite objSite = new SPSite(URL)) { using (SPWeb objWeb = objSite.OpenWeb()) { SPList objSourceList = null; SPList objDestinationList = null; try { objSourceList = objWeb.Lists["Source"]; } catch(Exception ex) { Console.WriteLine("Error opening source list"); Console.WriteLine(ex.Message); } try { objDestinationList = objWeb.Lists["Destination"]; } catch (Exception ex) { Console.WriteLine("Error opening destination list"); Console.WriteLine(ex.Message); } string ItemURL = string.Empty; if (objSourceList != null && objDestinationList != null) { foreach (SPListItem objSourceItem in objSourceList.Items) { ItemURL = string.Format(@"{0}/Destination/{1}", objDestinationList.ParentWeb.Url, objSourceItem.Name); objSourceItem.CopyTo(ItemURL); objSourceItem.UnlinkFromCopySource(); } } } } Thanks

  • Copy whole SQL Server database into JSON from Python

    - by Oli
    I facing an atypical conversion problem. About a decade ago I coded up a large site in ASP. Over the years this turned into ASP.NET but kept the same database. I've just re-done the site in Django and I've copied all the core data but before I cancel my account with the host, I need to make sure I've got a long-term backup of the data so if it turns out I'm missing something, I can copy it from a local copy. To complicate matters, I no longer have Windows. I moved to Ubuntu on all my machines some time back. I could ask the host to send me a backup but having no access to a machine with MSSQL, I wouldn't be able to use that if I needed to. So I'm looking for something that does: db = {} for table in database: db[table.name] = [row for row in table] And then I could serialize db off somewhere for later consumption... But how do I do the table iteration? Is there an easier way to do all of this? Can MSSQL do a cross-platform SQLDump (inc data)? For previous MSSQL I've used pymssql but I don't know how to iterate the tables and copy rows (ideally with column headers so I can tell what the data is). I'm not looking for much code but I need a poke in the right direction.

  • Copy an entity in Google App Engine datastore in Python without knowing property names at 'compile'

    - by Gordon Worley
    In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in. How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else. ETA: Well, I tried it out and I did run into problems. I would like to make my copy in such a way that I don't have to know the names of the properties when I write the code. My thinking was to do this: #theThing = a particular entity we pull from the datastore with model Thing copyThing = Thing(user = user) for thingProperty in theThing.properties(): copyThing.__setattr__(thingProperty[0], thingProperty[1]) This executes without any errors... until I try to pull copyThing from the datastore, at which point I discover that all of the properties are set to None (with the exception of the user and key, obviously). So clearly this code is doing something, since it's replacing the defaults with None (all of the properties have a default value set), but not at all what I want. Suggestions?

  • Plist won't copy to documents directory

    - by John
    I have a plist file in my resources group in xcode. I am trying to copy this into my documents directory on app launch. I am using the following code (taken from a sqlite tutorial): BOOL success; NSError *error; NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *filePath = [documentsDirectory stringByAppendingString:@"ActiveFeedsPlist.plist"]; success = [fileManager fileExistsAtPath:filePath]; if (success) return; NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingFormat:@"ActiveFeedsPlist.plist"]; success = [fileManager copyItemAtPath:path toPath:filePath error:&error]; if (!success) { NSAssert1(0, @"Failed to copy Plist. Error %@", [error localizedDescription]); } I am given the error " * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to copy Plist. Error Operation could not be completed. No such file or directory'" in the console however. Any idea what is wrong? Thanks

  • Using shared_ptr to implement RCU (read-copy-update)?

    - by yongsun
    I'm very interested in the user-space RCU (read-copy-update), and trying to simulate one via tr1::shared_ptr, here is the code, while I'm really a newbie in concurrent programming, would some experts help me to review? The basic idea is, reader calls get_reading_copy() to gain the pointer of current protected data (let's say it's generation one, or G1). writer calls get_updating_copy() to gain a copy of the G1 (let's say it's G2), and only one writer is allowed to enter the critical section. After the updating is done, writer calls update() to do a swap, and make the m_data_ptr pointing to data G2. The ongoing readers and the writer now hold the shared_ptr of G1, and either a reader or a writer will eventually deallocate the G1 data. Any new readers would get the pointer to G2, and a new writer would get the copy of G2 (let's say G3). It's possible the G1 is not released yet, so multiple generations of data my co-exists. template <typename T> class rcu_protected { public: typedef T type; typedef std::tr1::shared_ptr<type> rcu_pointer; rcu_protected() : m_data_ptr (new type()) {} rcu_pointer get_reading_copy () { spin_until_eq (m_is_swapping, 0); return m_data_ptr; } rcu_pointer get_updating_copy () { spin_until_eq (m_is_swapping, 0); while (!CAS (m_is_writing, 0, 1)) {/* do sleep for back-off when exceeding maximum retry times */} rcu_pointer new_data_ptr(new type(*m_data_ptr)); // as spin_until_eq does not have memory barrier protection, // we need to place a read barrier to protect the loading of // new_data_ptr not to be re-ordered before its construction _ReadBarrier(); return new_data_ptr; } void update (rcu_pointer new_data_ptr) { while (!CAS (m_is_swapping, 0, 1)) {} m_data_ptr.swap (new_data_ptr); // as spin_until_eq does not have memory barrier protection, // we need to place a write barrier to protect the assignments of // m_is_writing/m_is_swapping be re-ordered bofore the swapping _WriteBarrier(); m_is_writing = 0; m_is_swapping = 0; } private: volatile long m_is_writing; volatile long m_is_swapping; rcu_pointer m_data_ptr; };

  • Copy constructor called even when returning by reference?

    - by Johnyy
    Hi, I am testing the return of local objects by reference. My original test went well but something else happens unexpected. #include <iostream> using namespace std; class MyInt { public: MyInt(int i){ value = new int(i); } ~MyInt(){ delete value; } int getValue(){ return *value; } MyInt(const MyInt &b){ cout<<"Copy"<<endl; } private: int* value; }; MyInt& returnref(){ MyInt a(10); cout<<"Returning from returnref()"<<endl; return a; } int main(){ MyInt a = returnref(); cout<<a.getValue()<<endl; return 0; } My console prints "Returning from ..." then "Copy" then a random value. My understanding of pass by reference is that it does not need to make any copy. Why is it not doing what I expected?

  • Secure Copy File from remote server via scp and os module in Python

    - by user1063572
    I'm pretty new to Python and programming. I'm trying to copy a file between two computers via a python script. However the code os.system("ssh " + hostname + " scp " + filepath + " " + user + "@" + localhost + ":" cwd) won't work. I think it needs a password, as descriped in How do I copy a file to a remote server in python using scp or ssh?. I didn't get any error logs, the file just won't show in my current working directory. However every other command with os.system("ssh " + hostname + "command") or os.popen("ssh " + hostname + "command") does work. - command = e.g. ls When I try ssh hostname scp file user@local:directory in the commandline it works without entering a password. I tried to combine os.popen commands with getpass and pxssh module to establish a ssh connection to the remote server and use it to send commands directly (I only tested it for an easy command): import pxssh import getpass ssh = pxssh.pxssh() ssh.force_password = True hostname = raw_input("Hostname: ") user = raw_input("Username: ") password = getpass.getpass("Password: ") ssh.login(hostname, user, password) test = os.popen("hostname") print test But I'm not able to put commands through to the remote server (print test shows, that hostname = local and not the remote server), however I'm sure, the conection is established. I thought it would be easier to establish a connection than always use "ssh " + hostname in the bash commands. I also tried some of the workarounds in How do I copy a file to a remote server in python using scp or ssh?, but I must admit due to lack of expirience I didn't get them to work. Thanks a lot for helping me.

  • extending the delphi TEditCopy action to also copy listbox items to clipboard

    - by PA
    I have a form with most of its functionality implemented using standard TAction. I have a menu, a toolbar, and some toobuttons. I have implemented clipboard copy/paste with no code at all, just using TEditCopy and TEditPaste actions. It works perfect in the TEdit and TMemo boxes I have. Now, I want it to work with TListBox, too. Specifically, I want to be able to copy the selected list item in a TListBox using the very same menuitems, key shortcuts and toolbuttons. So, I believe I will need to extend the TEditCopy Action. But it doesn't seem very straight forward to me. In particular, the TEditAction checks for the focused control to be a TCustomEdit control, which a TListBox it is not. I am a little affraid that it will be just too much work. The obvious alternative is to just forget about the standard actions and implement the copy to clipbard in the OnExecute method of a generic TAction. But, before giving up, do you have some idea, hint or trick that would help me extend the standard TEditCopy action?

  • Copy existing XML, duplicate element and modify

    - by Robert
    Hi, I have a tricky XSL problem at the moment. I need to copy the existing XML, copy a certain element (plus its child elements) and modify the value of two child-elements. The modifications are: divide value of the 'value' element by 110 and edit the value of the 'type' element from 'normal' to 'discount'. This is currently what I have: Current XML: <dataset> <data> <prices> <price> <value>50.00</value> <type>normal</type> </price> </prices> </data> </dataset> Expected result <dataset> <data> <prices> <price> <value>50.00</value> <type>normal</type> </price> <price> <value>45.00</value> <type>discount</type> </price> </prices> </data> </dataset> Any takers? I've gotten as far as copying the desired 'price' element using copy-of, but I'm stuck as to how to modify it next.

  • svn copy causes "...(403 Forbidden) in reponse to PROPFIND", other actions work

    - by Hops
    Just for a short bit of background, the reason I'm tracking this particular subversion oddity down is because I found it troubleshooting our new Maven setup (specifically the release plugin). release:prepare gives me the same error buried in a stack trace. Executing this command... svn copy http://[server]/svn/tran1/myproject/trunk http://[server]/svn/tran1/myproject/tags/testtag ...gives me the following error: svn: Server sent unexpected return value (403 Forbidden) in response to PROPFIND request for '/svn/tran1' I thought this might be an authentication issue, but I'm able to do pretty much every other subversion thing I can think of. Checkout, add, commit and update all work from the command line. And here's where it gets really weird... I can create branches using Eclipse's Subclipse plugin. This might not be all that strange if Eclipse isn't actually doing an svn copy. tran1 also has a sibling subversion repository next to it. The copy command works fine there. The URL it's trying to get permission for also looks wrong. It's asking about /svn/tran1, when the permissions are set up one level deeper /svn/tran1/myproject/ Any ideas what might be causing my error? Thanks.

  • Failing to use Array.Copy() in my WPF App

    - by Steven Wilson
    I am a C++ developer and recently started working on WPF. Well I am using Array.Copy() in my app and looks like I am not able to completely get the desired result. I had done in my C++ app as follows: static const signed char version[40] = { 'A', 'U', 'D', 'I', 'E', 'N', 'C', 'E', // name 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , // reserved, firmware size 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , // board number 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , // variant, version, serial 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 // date code, reserved }; unsigned char sendBuf[256] = {}; int memloc = 0; sendBuf[memloc++] = 0; sendBuf[memloc++] = 0; // fill in the audience header memcpy(sendBuf+memloc, version, 8); // the first 8 bytes memloc += 16; // the 8 copied, plus 8 reserved bytes I did the similar operation in my WPF (C#) app as follows: Byte[] sendBuf = new Byte[256]; char[] version = { 'A', 'U', 'D', 'I', 'E', 'N', 'C', 'E', // name '0', '0', '0', '0', '0', '0', '0', '0' , // reserved, firmware size '0', '0', '0', '0', '0', '0', '0', '0' , // board number '0', '0', '0', '0', '0', '0', '0', '0' , // variant, version, serial '0', '0', '0', '0', '0', '0', '0', '0' // date code, reserved }; // fill in the address to write to -- 0 sendBuf[memloc++] = 0; sendBuf[memloc++] = 0; // fill in the audience header Array.Copy(sendBuf + memloc, version, 8); // the first 8 bytes memloc += 16; But it throws me an error at Array.Copy(sendBuf + memloc, version, 8); as Operator '+' cannot be applied to operands of type 'byte[]' and 'int'. How can achieve this???? :) please help :)

  • How to copy depth buffer to CPU memory in DirectX?

    - by Ashwin
    I have code in OpenGL that uses glReadPixels to copy the depth buffer to a CPU memory buffer: glReadPixels(0, 0, w, h, GL_DEPTH_COMPONENT, GL_FLOAT, dbuf); How do I achieve the same in DirectX? I have looked at a similar question which gives the solution to copy the RGB buffer. I've tried to write similar code to copy the depth buffer: IDirect3DSurface9* d3dSurface; d3dDevice->GetDepthStencilSurface(&d3dSurface); D3DSURFACE_DESC d3dSurfaceDesc; d3dSurface->GetDesc(&d3dSurfaceDesc); IDirect3DSurface9* d3dOffSurface; d3dDevice->CreateOffscreenPlainSurface( d3dSurfaceDesc.Width, d3dSurfaceDesc.Height, D3DFMT_D32F_LOCKABLE, D3DPOOL_SCRATCH, &d3dOffSurface, NULL); // FAILS: D3DERR_INVALIDCALL D3DXLoadSurfaceFromSurface( d3dOffSurface, NULL, NULL, d3dSurface, NULL, NULL, D3DX_FILTER_NONE, 0); // Copy from offscreen surface to CPU memory ... The code fails on the call to D3DXLoadSurfaceFromSurface. It returns the error value D3DERR_INVALIDCALL. What is wrong with my code?

  • STL vector reserve() and copy()

    - by natersoz
    Greetings, I am trying to perform a copy from one vector (vec1) to another vector (vec2) using the following 2 abbreviated lines of code (full test app follows): vec2.reserve( vec1.size() ); copy(vec1.begin(), vec1.end(), vec2.begin()); While the call to vec2 sets the capacity of vector vec2, the copying of data to vec2 seems to not fill in the values from vec1 to vec2. Replacing the copy() function with calls to push_back() works as expected. What am I missing here? Thanks for your help. vectest.cpp test program followed by resulting output follows. Compiler: gcc 3.4.4 on cygwin. Nat /** * vectest.cpp */ #include <iostream> #include <vector> using namespace std; int main() { vector<int> vec1; vector<int> vec2; vec1.push_back(1); vec1.push_back(2); vec1.push_back(3); vec1.push_back(4); vec1.push_back(5); vec1.push_back(6); vec1.push_back(7); vec2.reserve( vec1.size() ); copy(vec1.begin(), vec1.end(), vec2.begin()); cout << "vec1.size() = " << vec1.size() << endl; cout << "vec1.capacity() = " << vec1.capacity() << endl; cout << "vec1: "; for( vector<int>::const_iterator iter = vec1.begin(); iter < vec1.end(); ++iter ) { cout << *iter << " "; } cout << endl; cout << "vec2.size() = " << vec2.size() << endl; cout << "vec2.capacity() = " << vec2.capacity() << endl; cout << "vec2: "; for( vector<int>::const_iterator iter = vec2.begin(); iter < vec2.end(); ++iter ) { cout << *iter << endl; } cout << endl; } output: vec1.size() = 7 vec1.capacity() = 8 vec1: 1 2 3 4 5 6 7 vec2.size() = 0 vec2.capacity() = 7 vec2:

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • How do I use text in one cell to trigger row to be copied on another sheet in Excel?

    - by Brian Eby
    I provide all of the cut lists for our cabinet manufacturing in Excel. I tally all parts for the entire job on the first worksheet in an Excel file, and then filter the rows based on the "Material" column, and manually copy/paste each row in to its own material-specific worksheet (example: I filter "Materials" column for "Maple Ply", and then copy all "Maple Ply" rows to the "Maple Ply" worksheet). Then the material specific worksheets are sent to the shop floor for cutting. This is time consuming, and if I need to change any data in the first page, I have to go and manually update the copied row in its material-specific page. Is there any way to make each material page "look" for its material, and automatically populate itself with any row that has the appropriate material in the material column (example: any time I enter "Maple Ply" in the material column of sheet one, that row is automatically copied to the "Maple Ply" worksheet)? If so, could this link be dynamic, rather than just a copy, so that if I change a cell in a particular row on sheet one, that data is also updated on the material-specific worksheet copy? Thank you, Brian

  • Java: Copying an exe-file and launching afterwards fails

    - by Philip
    Hi, I want to copy an existing .exe-file from one directory to another and launch it afterwards with Java. Like this: FileIO.copy( new File( sourceFile ), new File( targetFile ) ); System.out.println( "Existing: " + new File( targetFile ).exists() ); System.out.println( "Launching " + targetFile ); String cmd[] = { targetFile }; Process p = Runtime.getRuntime().exec( cmd ); p.waitFor(); System.out.println( "Result: " + p.exitValue() ); The output is like this: Existing: true Launching C:\test\Launcher.new.exe Result: 2 So Java says that the file is valid and existing, but Windows just can't launch the process because it thinks the file is not there. The pathes are absolute and with backslashes. I also have all permissions on the files so I'm allowed to execute them. The Launcher.new.exe is generated by Launch4j, so it's more or less standalone. At least it doesn't depend on DLLs in the same folder. But strange: It works when I copy and launch the notepad.exe. One more strange thing: If I don't copy the file by Java but by hand, the launching also fails with the same error. OS is Vista with SP1. Any clue?

  • Is there any way to do an emacs-like yank in vim?

    - by Jason Baker
    In emacs, yanking works something like this: if you delete something, it can be yanked back into another position. In other words, emacs's yank is sort of like cut and paste. On the other hand, it seems like vim's yank is like copy and paste: I can yank something and then paste it elsewhere, but the original text is still there. Is there any way to cut the text rather than just copying it in vim?

  • Batch change modified/created dates?

    - by Billiam
    I recently bought new hard drives for my NAS. This means that I'm copying all the data off the NAS, upgrading it, and then moving the data back. I've gotten as far as copying the data from the NAS, but every file's modified/created date has been changed to when it was copied (today). Is there a way, keeping in mind that I have the original data, to batch update the modified/created dates on the copied files without having to copy them over again (we're talking over a terabyte of data)?
