  • Import OLE Object from Access to MySQL

    - by SecretDeveloper
    I have a table in an access table which contains Product entries, one of the columns has a jpg image stored as an OLE Object. I am trying to import this table to MySQL but nothing seems to work. I have tried the MySQL migration tool but that has a known issue with Access and OLE Objects. (The issue being it doesnt work and leaves the fields blank) I also tried the suggestion on this site and while the data is imported it seems as though the image is getting corrupted in the transfer. When i try to preview the image i just get a binary view, if i save it on disk as a jpg image and try to open it i get an error stating the image is corrupt. The images in Access are fine and can be previewed. Access is storing the data as an OLE Object and when i import it to MySql it is saved in a MediumBlob field. Has anyone had this issue before and how did they resolve it ?

  • Are these AVAudioSettings right?

    - by Dyldo42
    self.recordSettings = [NSMutableDictionary dictionary]; [recordSettings setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey]; [recordSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; [recordSettings setValue:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey]; recordSettings is declared in my view's header file and initialised in its viewDidLoad method. For some reason, everything is working in the simulator, but on a device, the [recorder record] method is returning NO. The only theory I have is that something in the recordSettings isn't compatible with an actual device. Any ideas?

  • Android: Context menu doesn't show up for ListView with members defined by LinearLayout?

    - by RandomEngy
    I've got a ListActivity and ListView and I've bound some data to it. The data shows up fine, and I've also registered a context menu for the view. When I display the list items as just a simple TextView, it works fine: <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> However when I try something a bit more complex, like show the name and a CheckBox, the menu never shows up: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <CheckBox android:id="@+id/namecheckbox" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> Can long-presses work on more complex elements? I'm building on 2.1.

  • How can I keep a WPF Image from blocking if the ImageSource references an unreachable Url?

    - by Corey O'Brien
    I'm writing a WPF application and trying to bind an image to my view model with the following XAML: <Image Source="{Binding Author.IconUrl, IsAsync=True}" /> The problem is that the image URLs are defined by users and can often refer to images hosted on intranet web servers. When the WPF application is run remotely, it locks up while trying to resolve the images that are now unreachable. I thought the "IsAsync" binding property would cause the load to happen in the background, but it appears that the DNS resolution may still happen in the main thread? What can I do to keep my app from locking, even if the images are unreachable? Thanks, Corey

  • Is it possible to get an NSView to pass rightMouseDown: to the next responder without subclassing?

    - by Benedict Cohen
    I have a view which contains a few subviews: mainView subViewA subViewB SubViewC mainView is an NSView constructed from a nib and is controlled with an NSViewController subclass. The subviews are standard views such as NSTextField and NSImageView and are configured to be non-editable. I want mainView to receive rightMouseDown: even when the event is triggered in one of the subviews. The default implementation of rightMouseDown: in NSResponder passes the event to the next responder, but NSView changes the default behaviour and does not pass it to the next responder. I could subclass all of the subviews but this doesn't seem like a very elegant or maintainable solution. How can I get the subviews to pass rightMouseDown: messages to the next responder without subclassing all of the subviews?

  • Symfony app - how to add calculated fields to Propel objects?

    - by Thomas Kohl
    What is the best way of working with calculated fields of Propel objects? Say I have an object "Customer" that has a corresponding table "customers" and each column corresponds to an attribute of my object. What I would like to do is: add a calculated attribute "Number of completed orders" to my object when using it on View A but not on Views B and C. The calculated attribute is a COUNT() of "Order" objects linked to my "Customer" object via ID. What I can do now is to first select all Customer objects, then iteratively count Orders for all of them, but I'd think doing it in a single query would improve performance. But I cannot properly "hydrate" my Propel object since it does not contain the definition of the calculated field(s). How would you approach it?

  • ASP.Net: User controls added to placeholder dynamically cannot retrieve values.

    - by Steve Horn
    I am adding some user controls dynamically to a PlaceHolder server control. My user control consists of some labels and some textbox controls. When I submit the form and try to view the contents of the textboxes (within each user control) on the server, they are empty. When the postback completes, the textboxes have the data that I entered prior to postback. This tells me that the text in the boxes are being retained through ViewState. I just don't know why I can't find them when I'm debugging. Can someone please tell me why I would not be seeing the data the user entered on the server? Thanks for any help.

  • UILabel background color not updating in UITableView

    - by Joey
    I'm having a perplexing problem with a simple UILabel I put on a cell in a UITableView. I enter a separate view after tapping on a row, like many UITableViews. In there, I update the cell so that when I return to the rows, it should be updated, with this: MyTableViewCell* cell = (MyTableViewCell*) [mTableView cellForRowAtIndexPath: [NSIndexPath indexPathForRow:mActiveRow inSection:0]]; cell.myLabel.text = @"New Value"; // updated text cell.myLabel.backgroundColor = [UIColor greenColor]; // updated color When I return, though, only the text is updated, not the color. When I scroll the row off the screen and return it refreshes properly via another path of code that has exactly the same code. Could there be some trigger to refresh specifically the background color of the UILabel? I'm not sure why the text will refresh but the color won't.

  • Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

    - by user1656286
    I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.

  • Get a image from a uiview

    - by Monobono
    Hi I want to perform a shrink animation on a UITableVIew. I experimented a bit and found out that the animation runs much faster when I shrink a UIImageView with an image of the current state of the tableview instead of shrinking the table view itself. I grabbed the image in a method in my main viewcontroller prior to the animation: UIGraphicsBeginImageContext(mainTableView.bounds.size); [resizeContainer.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); Works like a charm, at least almost. On very rare occasions I get weird graphic glitches, where the UIImage starts to overlap a toolbar that lies underneath it. I just want to make sure that I am getting the image in the right way. I am laking the necessary understand of GraphicContexts to be sure about it. To cut a long story short, is my code correct? Thx

    Hey guys, I'm using Jquery UI sortable in my current project to make boxes drag and drop-able into new columns. It works in all modern browsers apart from ie7, in which you can drag and drop, but when you drop, it completely ruins the content of the box you're dropping. I've sat and looked at this for ages and have no clue what the problem is. Do any of you have any idea? Here's a demo of what's going on. View it in ie7.

  • RoR Devise: Sign in with username OR email

    - by Patrick Oscity
    Whats the best way to enable users to log in with their email address OR their username? I am using warden + devise for authentication. I think it probably won't be too hard to do it but i guess i need some advice here on where to put all the stuff that is needed. Perhaps devise devise already provides this feature? like in the config/initializers/devise.rb you would write: config.authentication_keys = [ :email, :username ] To require both username AND email for signing in. But i really want to have only one field for both username and email and require only one of them. I'll just visualize that with some ASCII art, it should look something like this in the view: Username or Email: [____________________] Password: [____________________] [Sign In]

I'm pretty sure the answer contains "memory management" but I can't get the point... @interface RootViewController : UIViewController { NSTimer *timer; } -(void)changeView:(NSTimer*)theTimer; @property(nonatomic,retain) NSTimer *timer; ... @implementation RootViewController @synthesize timer; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[self navigationController] setNavigationBarHidden:YES]; timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(changeView:) userInfo:nil repeats:NO]; } -(void)changeView:(NSTimer*)theTimer { NSLog(@"timer fired"); //Crash here, but only if called using a timer [[self navigationController] pushViewController:list animated:YES]; }

  • ASP.NET GridView and UpdatePanel

    - by Echilon
    I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.
