• Calling "function" on control

  - by Sascha

  Hi, I'm using MVVM in my WPF project. Now I want to display a subwindow when someone presses a button. To achieve this classically I would call the Show() method. What I want now, to keep my application clear, is to bind the button to the Show() function of the subwindow. As the button click (menu click, whatever) is not always allowed I wrote a custom command that evaluates if the command can be executed. However, I did not found a clue how to call the function of that control in a clean way. Is this the point to do some classic style (code in the frontend)? -sa

• WPF Binding Question - Change Label Text based on Modifier Key Control

  - by Chuck Savage

  I have a context menu, that I'd like to change the Header based on whether the Control Key is pressed or not. Right now I have, <MenuItem Header="Send To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> I'd like based on the Control Key being down to be, <MenuItem Header="Move To"> <MenuItem ... /> <MenuItem ... /> </MenuItem> All I really need to do is change the Header text, because inside the code I know how to check for the Modifier key being Control.

• jQuery form wizard - named anchor links

  - by Jackson

  Hi Team, Using: http://home.aland.net/sundman/ to split a complex form in to 4 steps. As well as as the 'next, back and submit' form buttons, I have created a menu above the form: step 1, step 2, step 3, step 4 linking to the hash tags #: #, #1, #2, #3 so the visitor can decide which step they want to view / edit. This works fine in firefox, but in IE and Chrome it does not seem to work. Anyone have experience with hte jQuery history plugin that can tell me the best way to accomplish this? I would like to link to the form but it is in a password protected area and subject to our NDA. If need be I could try and replicate the issue with a form on our server and link here. Thanks, Jack

• Javascript window.onunload fires off after Page_Load

  - by gnomixa

  I have noticed that window.onunload event fires off AFTER page_load event which makes no sense. This behaviour is creating an issue for me - in my unonload I clear the session, so if the Page_Load first BEFORE onunload, there are errors on the page displayed. I would expect the javascript onunload to fire BEFORE Page_Load....is that the correct assumption? TO CLARIFY: Let's assume I am on page test.aspx, then I click on the link that goes to the same page (say I click on a menu), what I observe is that Page_Load fires first, then onunload fires off. Makes no sense at all.

• Lotus Notes - Fails to move inbox article to subfolder

  - by Klaptrap

  Lotus Notes 8.5 - yuck! User is trying to move an email from the Inbox into a subfolder and is using the menu option (not dragging & dropping) the email simply fails to move. It just appears again in the inbox. Drag and drop has the same effect! I have checked that it is a failure to move and not just a copy/delete issue. I am not a Notes adminstrator, being more of a MS Exchange administrator by career path and have no idea what to be looking for.

• Android SDK and AVD manager will not run from Eclipse after upgrade to SDK 5 and ADT 0.9.6

  - by user303944

  Using Windows 7, 64 bit system. Prior to upgrade I was able to run "Android SDK and AVD manager" from Eclipse via a tool bar icon and menu option, both of which still exist. However now nothing happens when I try to run the manager. As a result I can't start an emulator from within Eclipse. When I use Eclipse to run an Android app, the first emulator I installed is automatically started. Using Windows Explorer, I can still run the manager from the SDK directory in which the update was applied (the update didn't change the location of the SDK). If I run the manager and start multiple emulators and then Run an app from Eclipse, it sees the emulators and allows me to choose one as before. This is a satisfactory work-around, but it would be nice if the manager were fully integrated into Eclipse as it was before.

• Silverlight like login/register control in WPF

  - by user293545

  If you have created a silverlight business application you will see that in the top righthand corner on the menu is a login hyperlink. Pressing it opens up a childwindow that displays a login control, within that control is another hyperlink that says "Register" if you press it, it flips the control 180 degrees around from the login control to the register control. I really like this type of animation and want to do something similar in WPF for a project I am working on. However I am not sure how to do it, has anyone done this or knows where I can find some more information on how to achieve it? Thank you

  Hi everyone, i'm trying to realize non-editable QTableView with widgets in cells that should contain clickable listed text. With following code i'm setting widget in definite cell: view = QTableView() label = QLabel( <some html text> ) ... view.setIndexWidget(index, label) I used html to make label's text clickable, but links became blue with underline and moreover by clicking on it with right mouse button appears popup menu with "Copy Link Locaion" option, where i wanted to place some hidden information instead of url and of course do not let user see this info.

Can you advice what should i use for this purpose? Thank you in advance Serge

• Using mergedModelFromBundles: and versioning (CoreData)

  - by charlax

  Hi everybody, I'm trying to use the migration feature in CoreData. I've followed the Apple Documentation. I have a problem in the following method: /** Returns the managed object model for the application. If the model doesn't already exist, it is created by merging all of the models found in the application bundle. */ - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel != nil) { return managedObjectModel; } /* * NSInvalidArgumentException', reason: '*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil' * 2010-02-17 16:27:15.338 Patrimoine[3037:207] */ managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; return managedObjectModel; } It appears that there is the same problem on http://iphonedevelopment.blogspot.com/2009/09/core-data-migration-problems.html Yet I did choose the method Apple suggests, by using the menu option "Add Model Version". Do you have any idea?

• Is there any JavaScript Library to intelligently truncate strings?

  - by j0ker

  I need to truncate strings in a side menu to make the fit into a div without a linebreak. The divs have a fixed width. I'm looking for a library to do that for me. If a string is too long to fit into the div, it should be truncated like: <div>This string is too long</div> == <div>This string is...ong</div> As you can see, the string is not only truncated by an ellipsis but the last three letters are also visible. This is meant to increase readability. The truncation should not care about spaces. Does anyone know of a library that includes such functionality? We're mainly using jQuery throughout the project. Thanks in advance!

• iPad UIViewController loads as portrait when device is in landscape

  - by jud

  I have an application with 3 view controllers. They are all have shouldAutoRotateToInterfaceOrientation returning YES. The first two, my main menu and my submenu both autorotate just fine. The third viewcontroller, which programatically loads a UIImageView from a jpg file in the program's bundle, will only display in portrait. In the viewcontroller containing the image, i have this: NSString *imageName = [NSString stringWithFormat:@"%@-00%d.jpg",setPrefix,imageNumber]; UIImageView *pictureView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]]; pictureView.frame = CGRectMake(0, 0, 1024, 768); [self.view addSubview:pictureView]; and again, I have shouldAutoRotateToInterfaceOrientation returning YES for all orientations. My image shows up, but is sideways, and the 0,0,1024,768 values I used to make my rectangle start from the top right corner going down, instead of starting at the top left and going across (holding in landscape). Am I missing a parameter I need to set in order to ensure the imageview shows up in landscape instead of portrait?

• Detecting your application's install path in Java?

  - by Danny King

  Hi, I have made a small application in Java and I would like to make a windows installer for it using the Nullsoft Scriptable Install System (http://nsis.sourceforge.net/Main_Page). The application I made needs to save user preferences somewhere and it currently saves it in the user's home directory (e.g. c:\Users\danny or /home/users/danny). However if the windows installer installs the application to e.g. c:\Program Files\whatever\ I should probably save the preferences file there too, right? How would I detect that directory path in Java? What would be a good cross-platform approach to this without losing the benefits of a windows uninstaller for windows users e.g. start menu icons, installer option, etc? Should I just continue saving my preferences in the user's home path and clutter it up? Thanks very much,

• Splitting up/merging windows in WPF

  - by drasto

  I'm new to WPF but I need to implement following functionality: I have a window that contains one Grid (might be changed to stack panel or something else). In that Grid I have 2 columns, each of them contains another Grid. Lets call them gridFirst and gridSecond. There is also GridSplitter in first column allowing to resize the columns. I want to provide a button that will allow to separate gridFirst from this window and display it "as it is" in another window. How do I do that? It would be nice if the new window had a same menu as the original window without me having to copy-paste (that not a good coding practise) all its code to the new window. Thanks for answers

• Select a subset of foreign key elements in inlineformset_factory in Django

  - by Enis Afgan

  Hello, I have a model with two foreign keys: class Model1(models.Model): model_a = models.ForeignKey(ModelA) model_b = models.ForeignKey(ModelB) value = models.IntegerField() Then, I create an inline formset class, like so: an_inline_formset = inlineformset_factory(ModelA, Model1, fk_name="model_a") and then instantiate it, like so: a_formset = an_inline_formset(request.POST, instance=model_A_object) Once this formset gets rendered in a template/page, there is ChoiceField associated with the model_b field. The problem I'm having is that the elements in the resulting drop down menu include all of the elements found in ModelB table. I need to select a subset of those based on some criteria from ModelB. At the same time, I need to keep the reference to the instance of model_A_object when instantiating inlineformset_factory and, therefore, I can't just use this example. Any suggestions?

• speed up a sql query to mysql?

  - by fayer

  in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!
