  • Using resources with the same name in Xcode

    - by Roberto
    Is there a way to add multiple resources with the same name to an Xcode project and have 1 of them take priority over the others? Example: I added 2 files, both called icon.png, to an Xcode project. They are on different folders in the file system (Folder1/icon.png and Folder2/icon.png) and on different groups in Xcode. Is there a way to tell Xcode to have Folder2/icon.png take priority over Folder1/icon.png? And if only 1 icon.png exists, then use that one. Thanks. EDIT (2010-12-23): You can have multiple files with the same name in an Xcode project even if they are not in separate folder references, but they are in separate groups. Once compiled, the app bundle (which will be flat with no folders in it), will only have one copy of the file (icon.png). How do you pick which copy of the file to use? I was told that you can do this for BlackBerry. It works something like this: The compiler will go down the list of files in the project and start adding them to the app bundle. If it sees a duplicate, it will overwrite it (or not), so the files at the bottom (or at the top) will have higher precedence and will be the final bundle.

  • .NET Application with SQL Server CE Database

    - by blu
    I just started using SQL Server CE 3.5 in my WinForms Application (C# in VS 2008 SP1). I've noticed a couple of interesting things I'd like some input on: 1. Copying of sdf file to bin My sdf file is located inside of an Infrastructure project that houses my repository implementations. When the application is first debugged the sdf was copied to debug\bin. This is where all future reads/writes operate. At some point when this is deployed the file will go into a data folder using Click Once, but during development where should I be putting this sdf? Is having it in the bin typical, or are there any other recommendations? 2. Updating sdf It appears that writing to the sdf file does not immediately update the database. I am using Linq-to-SQL and am calling SubmitChanges, but on read the values are not returned. However if I close the application and re-open it the added value is there. Is there an additional flush step I need to take? What is causing this, file locking, buffering, something else? Update 3. Unit Tests I have an MS test project, and the sdf file is not being copied to the correct output directory. I have the settings: Build Action: Content Copy to Output Directory: Copy Always The message is: System.Data.SqlServerCe.SqlCeException: The database file cannot be found. Check the path to the database. I appreciate any guidance on these questions, thanks. If there is a tutorial other than what is on MSDN that you know about that would be great too. Working with CE is proving to be a difficult task and I welcome any help I can find.

  • VisualSVN How to roll back the revision number ?

    - by Ita
    The company I work in has suffered a major server failure. During this failure the SVN Repository was lost. But there is still hope ! We have an old backup of the repository which I've managed to successfully restore using VisualSVN. The problem I'm facing now is that I can't update / commit pre-failure checkedout folders. The reason for this problem is that for instance: a local folder has a revision number of 2361, while the repository itself holds a revision number of 2290, which is older. Is there a way to deal with this issue ? Can I some how change the revision numbers on either the local copy or the server copy? A few points: I'm using TortoiseSVN 1.6.6. I can checkout folders from the repo and the connection is active. I've picked one of my folders and used the Relocate option on it. This helped me see that there is something wrong with the revision number I've experimented a bit with the merge option but this lead me now where special. (I'm open for suggestions ) Thank you for your time, Ita

  • Vector does reallocation on every push_back

    - by Amrish
    IDE - Visual Studio 2008, Visual C++ I have a custom class Class1 with a copy constructor to it. I also have a vector Data is inserted using the following code Class1* objClass1; vector<Class1> vClass1; for(int i=0;i<1000;i++) { objClass1 = new Class1(); vClass1.push_back(*objClass1); delete objClass1; } Now on every insert, the vector gets re-allocated and all the existing contents are copied to new locations. For example, if the vector has 5 elements and if I insert the 6th one, the previous 5 elements along with the new one gets copied to a new location (I figured it out by adding log statements in the copy constructors.) On using reserve(), this however does not happen as expected! I have the following questions Is it mandatory to always use the reserve statement? Does vector does a reallocation every time I do a push_back; or does it happen because I am debugging?

  • jQuery remove SELECT options based on another SELECT selected on change and on load

    - by John Sieber
    I'm using the following jQuery code to remove options from a select and it is working well. But instead of it only executing when the theOption2 select is changed I would also like it to work when the page is loaded depending on the selected item that is selected. I tried using the a copy of the script and changing the .change to .load and also tried using (window).load without the desired results. Essentially, I need the script to execute on change of the Options1 and on the loading of the page. Any help with this would be greatly appreciated. <script type="text/javascript"> $(document).ready(function() { //copy the second select, so we can easily reset it var selectClone = $('#theOptions2').clone(); $('#theOptions1').change(function() { var val = parseInt($(this).val()); //reset the second select on each change $('#theOptions2').html(selectClone.html()) switch(val) { //if 2 is selected remove C case 2 : $('#theOptions2').find('option:contains(c)').remove();break; //if 3 is selected remove A case 3 : $('#theOptions2').find('option:contains(a)').remove();break; } }); }); </script> <select id="theOptions1"> <option value="1">1</option> <option value="2" selected="selected">2</option> <option value="3">3</option> </select> <br /> <select id="theOptions2"> <option>a</option> <option>b</option> <option>c</option> </select>

  • Micrsoft Silverlight 3 cannot create service reference to localhost:port

    - by Monte
    Windows Server 2003 (IIS 6) Visual Studio 2008 .NET FrameWork 3.5 SP1 I am a .NET developer for a living and I have over 40 hours in the problem Project type = "Silverlight Navigation Application", "APS.NET Web Site" (when I tried it as "ASP.NET Web Application Project" I could not copy it to the production web site - well I could copy it but I could not make it run) Created a service.cs on the .Web side of the application. Created a reference to that service.cs on the Silverlight side. For a time all is good as I can reference the service as localhost:port (e.g. localhost:1374) in Visual Studio and debug both Silverlight side and service.cs To access the application in production mode (from IE) I update the service refrence and replace localhost:port with the IP address. The problem with the IP address is I cannot debug the service.cs so I have to change it back to localhost:port to debug. Now to the problem. After a period of time localhost:port just plain breaks. I get an error message no service at the other end Yes I know the port can change - that is not the problem - the port on the service side just plain breaks! For example from Visual Studio from the Silverlight side of the project right click "Service Reference", "Add Service Reverence". It finds 1 service in the application on a port. But when I click that service under "Services:" in the modal dialog box "Add Service Reference" I get an error: There was an error downloading 'http://localhost:1377/SehaleCSS.Web/Service.svc'. The request failed with the error message: -- Could not load file or assembly 'App_Web_tipnndfq, If I go back to the IP address the service is repsponding (with the right answer) The service just plain goes a while responding to localhost:port and then fails Even making NO change to service.cs it go a while then fails as a localhost:port It is not IIS environmental as I can go back to a prior saved version of the code and it works Something is happening that the .web side of the application is failing. It still works as an IP and it still exposes itself as a localhost:port but it fails to properly repsonde as a localhost:port.

  • Send Automated Email through Windows Service that has an embedded image using C#

    - by Refracted Paladin
    I already have a C# windows service that we use internally to monitor a directory on our network and when it detects a change sends off an email using our internal SMTP server to the specified groups of people. Now I need to embedd an image in that automated email. I understand that I need to create an AlternateView and a Linked Resource and use the Linked Resource's cID in the AlternateView, correct. What I do not understand is where do I put the image? Should I add it to my service project and set Copy to Output Directory = Copy Always? If so, how would I then access when creating my LinkedResource? Also, where do I put the image on the Server hosting the Service? Here is what I have so far but it doesn't seem to work. I don't get any errors, that I am aware of, but I do not get an email either. I am guessing it is looking for the image but that I do not have it in the correct location. // This event is called when an object(file,folder) is created in the srcPath void WatcherCreated(object source , FileSystemEventArgs e) { var folderName = e.Name; var folderPath = e.FullPath; MailMessage mail = new MailMessage(); mail.From = new MailAddress("[email protected]"); mail.To.Add("[email protected]"); mail.Subject = "New Enrollment for " + folderName; AlternateView plainView = AlternateView.CreateAlternateViewFromString("This is the plain text view", null, "text/html"); AlternateView htmlView = AlternateView.CreateAlternateViewFromString("Here is an embedded image. <img src=cid:enrollProcessID>", null, "text/html"); LinkedResource imageResourceLink = new LinkedResource("EnrollmentProcess.jpg") {ContentId = "enrollProcessID"}; htmlView.LinkedResources.Add(imageResourceLink); mail.AlternateViews.Add(plainView); mail.AlternateViews.Add(htmlView); var smtp = new SmtpClient("internalSMTP"); smtp.Send(mail); }

  • local vs core contoller

    - by latvian
    Hi, I am adding new column and action in the local admin app/code/local/Mage/Adminhtml/Block/Catalog/Product/Grid.php which works fine, however. The local controller/app/code/local/Mage/Adminhtml/Block/Catalog/Product.php is not being used or is not overloading the admin one /app/code/core/Mage/Adminhtml/Block/Catalog/Product.php. This is almost fresh install of Magento 1.4.0.1. I am the only one working, so i know it is not overloaded by some custom controller. I have disabled all custom modules. I have rolled back most of my changes. I have checked /etc/Modules/Mage_Catalog.xml. Refreshed cache all possible ways, loged in and out. Nothing....still using the core contoller copy. why? How do you troubleshoot, meaning, at what moment magento decides using between core or local copies? ...its even more strange because it does not parse local Adminhtml config.xml but uses local Adminthml copy of Blocks. Any pointer would help. I would like to keep everything in local code. Thank You, Margots

  • FileSystemWatcher Work is Done?

    - by Snowy
    I setup a FsWatcher on a local filesystem directory. I only want to know when files are added to the directory so they can be moved to another filesystem. I seem to be able to detect when the first file is in, but actually I want to know when all files from a given copy operation are done. If I used Windows Explorer to copy files from one directory to another, Explorer would tell me that there are n seconds left in the transfer, so while there is some activity for the begin-transfer and end-transfer for each file, it appears that there is something for the begin-transfer and end-transfer for all files. I wonder if there is something similar that I can do just with the .NET Framework. I would like to know when "all" files are in and not just a single file in a "transaction". If there is nothing baked in, maybe I should come up with some kind of waiting/countering in order to only do my activity when a job is "done". Not sure if I'm making 100% sense on this one, please anyone comment. Thanks.

  • pointer, malloc and char in C

    - by user2534078
    im trying to copy a const char array to some place in the memory and point to it . lets say im defining this var under the main prog : char *p = NULL; and sending it to a function with a string : myFunc(&p, "Hello"); now i want that at the end of this function the pointer will point to the letter H but if i puts() it, it will print Hello . here is what i tried to do : void myFunc(char** ptr , const char strng[] ) { *ptr=(char *) malloc(sizeof(strng)); char * tmp=*ptr; int i=0; while (1) { *ptr[i]=strng[i]; if (strng[i]=='\0') break; i++; } *ptr=tmp; } i know its a rubbish now, but i would like to understand how to do it right, my idea was to allocate the needed memory, copy a char and move forward with the pointer, etc.. also i tried to make the ptr argument byreferenec (like &ptr) but with no success due to a problem with the lvalue and rvalue . the only thing is changeable for me is the function, and i would like not to use strings, but chars as this is and exercise . thanks for any help in advance.

  • compact XSLT code to drop N number of tags if all are null.

    This is my input xml: <root> <node1/> <node2/> <node3/> <node4/> <othertags/> </root> The output must be: <root> <othertags/> </root> if any of the 4 nodes isn't null then none of the tags must be dropped. example: <root> <node1/> <node2/> <node3/> <node4>sample_text</node4> <othertags/> </root> Then the output must be same as input xml. <root> <node1/> <node2/> <node3/> <node4>sample_text</node4> <othertags/> </root> This is the XSL code I have designed :: <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="/root/node1[.='' and ../node2/.='' and ../node3/.='' and ../node4/.=''] |/root/node2[.='' and ../node1/.='' and ../node3/.='' and ../node4/.=''] |/root/node3[.='' and ../node1/.='' and ../node2/.='' and ../node4/.=''] |/root/node4[.='' and ../node1/.='' and ../node2/.='' and ../node3/.='']"/> As you can see the code requires more effort and becomes more bulky as the number of nodes increase. Is there any alternative way to overcome this bottleneck?

  • Subversion unable to merge changes when using Dreamweaver

    - by neilc
    I've got a project running and we're using SVN as the version control. There are 3 devs on it. Dev1 = OSX + Textmate Dev2 = Windows 7 + Dreamweaver (plus tortoise svn) Dev3 = OSX + Coda Case 1 (expected): Dev1 and dev3 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev3 updates their copy. signup.php is merged as expected. All good. Case 2 (not expected): Dev1 and dev2 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev2 updates their copy. signup.php is always in conflict even though different parts of the file are worked on. This is not the expected behaviour experienced by dev1 and dev3. This works boths ways and each time dev1 updates dev2's changes he gets conflicts too. But never with dev3. Could this be down the way Dreamweaver is saving files ? Perhaps character encoding. We are all working in UTF8. These constant and unnecessary conflicts are becoming a massive distraction. Help !

  • Deleting from 2 arrays of dictionaries

    - by Matt Winters
    I have an array of dictionaries loaded from a plist (below) called arrayHistory. <plist version="1.0"> <array> <dict> <key>item</key> <string>1</string> <key>result</key> <string>8.1</string> <key>date</key> <date>2009-12-15T19:36:59Z</date> </dict> ... </array> </plist> I filter this array based on 'item' so that a second array, arrayHistoryDetail has the same structure as arrayHistory but only contains e.g. 'item's equal to '1'. These detail items are successfully displayed in a tableView. I then want to select an item from the tableView, and delete it from the tableView data source, arrayHistoryDetail (line 2 in the code below) - works, then I want to delete the item from the tableView itself (line 3 in the code below) - also works. My problem is that I also need to delete it from the original arrayHistory, so I tried the following: created a temporary dictionary as an ivar: NSMutableDictionary *tempDict; @property (nonatomic, retain) NSMutableDictionary *tempDict; Then my thinking was to make a copy in line 1 and remove it from the original array in line 4. 1 tempDict = [arrayHistoryDetail objectAtIndex: indexPath.row]; 2 [arrayHistoryDetail removeObjectAtIndex: indexPath.row]; 3 [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 4 [arrayHistory removeObject:tempDict]; Didn't work. Could someone please guide me in the right direction. I'm thinking that tempDict is a pointer and that removeObject needs a copy? I don't know. Thanks.

  • Extra NotifyIcon shown in system tray

    - by Kettch19
    I'm having an issue with an app where my NotifyIcon displays an extra icon. The steps to reproduce it are easy, but the problem is that the extra icon shows up after any of the actual codebehind we've added fires. Put simply, clicking a button triggers execution of method FooBar() which runs all the way through fine but its primary duty is to fire a backgroundworker to log into another of our apps. It only appears if this particular button is clicked. Strangely enough, we have a WndProc method override and if I step through until the extra NotifyIcon appears, it always appears during this method so something else beyond the codebehind must be triggering the behavior. Our WndProc method is currently (although I don't think it's caused by the WndProc): Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) 'Check for WM_COPYDATA message from other app or drag/drop action and handle message If m.Msg = NativeMethods.WM_COPYDATA Then ' get the standard message structure from lparam Dim CD As NativeMethods.COPYDATASTRUCT = m.GetLParam(GetType(NativeMethods.COPYDATASTRUCT)) 'setup byte array Dim B(CD.cbData) As Byte 'copy data from memory into array Runtime.InteropServices.Marshal.Copy(New IntPtr(CD.lpData), B, 0, CD.cbData) 'Get message as string and process ProcessWMCopyData(System.Text.Encoding.Default.GetString(B)) 'empty array Erase B 'set message result to 'true', meaning message handled m.Result = New IntPtr(1) End If 'pass on result and all messages not handled by this app MyBase.WndProc(m) End Sub The only place in the code where the NotifyIcon in question is manipulated at all is in the following event handler (again, don't think this is the culprit, but just for more info): Private Sub TrayIcon_MouseDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TrayIcon.MouseDoubleClick If Me.Visible Then Me.Hide() Else PositionBottomRight() Me.Show() End If End Sub The backgroundworker's DoWork is as follows (just a class call to log in to our other app, but again just for info): Private Sub LoginBackgroundWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles LoginBackgroundWorker.DoWork Settings.IsLoggedIn = _wdService.LogOn(Settings.UserName, Settings.Password) End Sub Does anyone else have ideas on what might be causing this or how to possibly further debug this? I've been banging my head on this without seeing a pattern so another set of eyes would be extremely appreciated. :) I've posted this on MSDN winforms forums as well and have had no luck there so far either.

  • pass a pointer of a class

    - by small_potato
    Say I have Class1 and Class2 and I want a shallow copy constructor for Class1. Class1 has a member variable, which is a pointer pointing to a Class2 instance. Also I have to be able to change the Class2 ptr is pointing at. in header file: class Class1 { Class2* ptr; ... } in source file: Class1::Class1() { ptr = new Class2(); } ...... Class2* Class1::Exchange(Class2* newClass2) { Class2* temp; ptr = newClass2; return temp; } ...... Now say Class1 original; Class1 shallowCopy(original); Class2* newClass2 = new Class2(); Class2* oldClass2; oldClass2 = orignal.Exchange(newClass2); delete oldClass2; now I want is associate original.ptr with shallowCopy.ptr, when I implement the shallow copy constructor, how do I make sure these two pointer always point at the same Class2? I mean in the class above, the oldClass2 is deleted, so ptr of shallowCopy is pointing at nothing. If I don't delete oldClass2, ptrs of original and shallowCopy are pointing at different Class2 instance.

  • subversion: how to manage tweaked files

    - by punk4funk
    Our group is considering moving to SVN. But, I can't seem to find a way to do the following: I need to make minor tweaks locally to about 20 files in the repository w/o having SVN consider them "changed" and included in the commit. (Changes like communication time-outs and logging levels.) Ideally I would want to merge the tweaked files to newer versions in the repository. (Keeping the tweaked local file up-to-date with committed changes form other users.) I can't imagine we're unique in wanting/needing this. Are there best practices around this type of use case? One thing I'm considering is putting all the tweaked files into a branched "tweaked" working copy. Then merging my tweaked files into my "official" working copy. Then using a script, which compares the "tweaked" and "official" working copies, to update my ignore list. The script would also un-ignore and alert me to any files that had tweaks and other changes that, presumably, needed to be committed to the repository. This seems kinda hacky and I can't imagine there's not a better way.

  • Cocoa Drag and Drop, reading back the data. [Newbie]

    - by kodai
    Ok, I have a NSOutlineView set up, and I want it to capture PDF's if a pdf is dragged into the NSOutlineView. My first question, I have the following code: [outlineView registerForDraggedTypes:[NSArray arrayWithObjects:NSStringPboardType, NSFilenamesPboardType, nil]]; In all the apple Docs and examples I've seen I've also seen something like MySupportedType being an object registered for dragging. What does this mean? Do I change the code to be: [outlineView registerForDraggedTypes:[NSArray arrayWithObjects:@"pdf", NSStringPboardType, NSFilenamesPboardType, nil]]; Currently I have it set up to recognize drag and drop, and I can even make it spit out the URL of the dragged file once the drag is accepted, however, this leads me to my second question. I want to keep a copy of those PDF's app side. I suppose, and correct me if I'm wrong, that the best way to do this is to grab the data off the clipboard, save it in some persistant store, and that's that. (as apposed to using some sort of copy command and literally copying the file to the app director.) That being said, I'm not sure how to do that. I've the code: - (BOOL)outlineView:(NSOutlineView *)ov acceptDrop:(id <NSDraggingInfo>)info item:(id)item childIndex:(NSInteger)childIndex { NSPasteboard *pboard = [info draggingPasteboard]; NSURL *fileURL; if ( [[pboard types] containsObject:NSURLPboardType] ) { fileURL = [NSURL URLFromPasteboard:pboard]; // Perform operation using the file’s URL } NSData *data = [pboard dataForType:@"NSPasteboardTypePDF"]; But this never actually gets any data. Like I said before, it does get the URL, just not the data. Does anyone have any advise on how to get this going? Thanks so much!

  • C++ STL question related to insert iterators and overloaded operators

    - by rshepherd
    #include <list> #include <set> #include <iterator> #include <algorithm> using namespace std; class MyContainer { public: string value; MyContainer& operator=(const string& s) { this->value = s; return *this; } }; int main() { list<string> strings; strings.push_back("0"); strings.push_back("1"); strings.push_back("2"); set<MyContainer> containers; copy(strings.begin(), strings.end(), inserter(containers, containers.end())); } The preceeding code does not compile. In standard C++ fashion the error output is verbose and difficult to understand. The key part seems to be this... /usr/include/c++/4.4/bits/stl_algobase.h:313: error: no match for ‘operator=’ in ‘__result.std::insert_iterator::operator* [with _Container = std::set, std::allocator ]() = __first.std::_List_iterator::operator* [with _Tp = std::basic_string, std::allocator ]()’ ...which I interpet to mean that the assignment operator needed is not defined. I took a look at the source code for insert_iterator and noted that it has overloaded the assignment operator. The copy algorithm must uses the insert iterators overloaded assignment operator to do its work(?). I guess that because my input iterator is on a container of strings and my output iterator is on a container of MyContainers that the overloaded insert_iterator assignment operator can no longer work. This is my best guess, but I am probably wrong. So, why exactly does this not work and how can I accomplish what I am trying to do?

  • localhost + staging + production environments?

    - by Kentor
    Hello, I have a website say www.livesite.com which is currently running. I have been developing a new version of the website on my local machine with http://localhost and then committing my changes with svn to www.testsite.com where I would test the site on the livesite.com server but under another domain (its the same environment as the live site but under a different domain). Now I am ready to release the new version to livesite.com. Doing it the first time is easy, I could just copy & paste everything from testsite.com to livesite.com (not sure its the best way to do it). I want to keep testsite.com as a testing site where I would push updates, test them and once satisfied move to livesite.com but I am not sure how to do that after the new site is launched.. I don't think copy pasting the whole directory is the right way of doing it and it will break the operations of current users on the livesite.com. I also want to keep my svn history on testsite.com. What is the correct way of doing this with SVN ? Thank you so much!

  • Web scrapping from a Google Chrome extension

    - by limoragni
    I've started to develop a Chrome extension to navigate and prform actions on a website. Until now the extension is able to receive a couple of parameters and check a set of radio-buttons, fill in a few inputs of a form and then submit it. What I want to do now is to repeat the process, but I'm stuck when the page is reloaded. And I don't know how can I do to make the script reacts to the finish of the request. The workflow I want to achieve is the following (is for automaticly copying a certain object): Popup side Enter the number of the Master object to copy Enter the base name of the copies (example Mod, so the I can iterate and add mod1, mod2, modn) Enter the number of copies Background side Select master Select standard options Fill in inputs Submit form Wait for the page to complete the request and continue to the next copy. (here I need help) The problem is on the repetition, the rest is taking care of. I assume that must be a way of dealing with requests. Any ideas? By the way I'm doing it all with the extension and tabs methods of google chrome plus javascript and jquery.

  • What is the fastest way to insert 100 000 records from one database to another?

    - by Pentium10
    I have a mobile application. My client has a large data set ~100.000 records. It's updated frequently. When we sync we need to copy from one database to another. I have attached the second database to the main, and run an insert into table select * from sync.table. This is extremely slow, it takes about 10 minutes I think. I noticed that the journal file gets increased step by step. How can I speed this up? EDITED 1 I have indexes off, and I have journal off. Using insert into table select * from sync.table it still takes 10 minutes. EDITED 2 If I run a query like select id,invitem,invid,cost from inventory where itemtype = 1 order by invitem limit 50 it takes 15-20 seconds. The table schema is: CREATE TABLE inventory ('id' INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, 'serverid' INTEGER NOT NULL DEFAULT 0, 'itemtype' INTEGER NOT NULL DEFAULT 0, 'invitem' VARCHAR, 'instock' FLOAT NOT NULL DEFAULT 0, 'cost' FLOAT NOT NULL DEFAULT 0, 'invid' VARCHAR, 'categoryid' INTEGER DEFAULT 0, 'pdacategoryid' INTEGER DEFAULT 0, 'notes' VARCHAR, 'threshold' INTEGER NOT NULL DEFAULT 0, 'ordered' INTEGER NOT NULL DEFAULT 0, 'supplier' VARCHAR, 'markup' FLOAT NOT NULL DEFAULT 0, 'taxfree' INTEGER NOT NULL DEFAULT 0, 'dirty' INTEGER NOT NULL DEFAULT 1, 'username' VARCHAR, 'version' INTEGER NOT NULL DEFAULT 15 ) Indexes are created like CREATE INDEX idx_inventory_categoryid ON inventory (pdacategoryid); CREATE INDEX idx_inventory_invitem ON inventory (invitem); CREATE INDEX idx_inventory_itemtype ON inventory (itemtype); I am wondering, the insert into ... select * from isn't the fastest built-in way to do massive data copy? EDITED 3 SQLite is serverless, so please stop voting a particular answer, because that is not the answer I'm sure.

  • MySQL Datefields: duplicate or calculate?

    - by Konerak
    We are using a table with a structure imposed upon us more than 10 years ago. We are allowed to add columns, but urged not to change existing columns. Certain columns are meant to represent dates, but are put in different format. Amongst others: * CHAR(6): YYMMDD * CHAR(6): DDMMYY * CHAR(8): YYYYMMDD * CHAR(8): DDMMYYYY * DATE * DATETIME Since we now would like to do some more complex queries, using advanced date functions, my manager proposed to d*uplicate those problem columns* to a proper FORMATTED_OLDCOLUMNNAME column using a DATE or DATETIME format. Is this the way to go? Couldn't we just use the STR_TO_DATE function each time we accessed the columns? To avoid every query having to copy-paste the function, I could still work with a view or a stored procedure, but duplicating data to avoid recalculation sounds wrong. Solutions I see (I guess I prefer 2.2.1) 1. Physically duplicate columns 1.1 In the same table 1.1.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.1.2 Maintained by a trigger on each modification 1.2 In a separate table 1.2.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.2.2 Maintained by a trigger on each modification 2. On-demand transformation 2.1 Each query has to perform the transformation 2.1.1 Using copy-paste in the source code 2.1.2 Using a library 2.1.3 Using a STORED PROCEDURE 2.2 A view performs the transformation 2.2.1 A separate table replacing the entire table 2.2.2 A separate table just adding the date-fields for the primary keys Am I right to say it's better to recalculate than to store? And would a view be a good solution?

  • C++ STL question related to insert iterators and sets

    - by rshepherd
    #include #include #include #include using namespace std; class MyContainer { public: string value; MyContainer& operator=(const string& s) { this->value = s; return *this; } }; int main() { list<string> strings; strings.push_back("0"); strings.push_back("1"); strings.push_back("2"); set<MyContainer> containers; copy(strings.begin(), strings.end(), inserter(containers, containers.end())); } The preceeding code does not compile. In typical STL style the error output is verbose and difficult to understand. The key part seems to be this... /usr/include/c++/4.4/bits/stl_algobase.h:313: error: no match for ‘operator=’ in ‘__result.std::insert_iterator::operator* [with _Container = std::set, std::allocator ]() = __first.std::_List_iterator::operator* [with _Tp = std::basic_string, std::allocator ]()’ ...which I interpet to mean that the assignment operator needed is not defined. I took a look at the source code for insert_iterator and noted that it has overloaded the assignment operator. The copy algorithm must uses the insert iterators overloaded assignment operator to do its work(?). I guess that because my input iterator is on a container of strings and my output iterator is on a container of MyContainers that the overloaded insert_iterator assignment operator can no longer work. This is my best guess, but I am probably wrong. So, why exactly does this not work and how can I accomplish what I am trying to do?
