chrome extension create window: alwaysOnTop - google-chrome-extension

According to that API definition:
https://developer.chrome.com/extensions/windows.html#type-Window
window has a (new) property called 'alwaysOnTop' (As I understand, it means that even if the user clicked somewhere else on the screen, this window sticks to the front, like 'chat for google' does).
I can't get how to create a window which has this property (chrome.window.create() doesn't contain it among the parameters it gets). I've tried several ways, like using the function that create gets and other options, but none worked. The console messages didn't help me to figure out what the right way is.
Could someone please post a short example that demonstrate a creation of such a window ?

alwaysOnTop is not a valid argument for chrome.windows.create.
Indeed, it is mentioned in the documentation, but listened under the Window type, which describes an object which is passed to many of the chrome.windows API method callbacks.
Compare chrome.windows.create#createData and the Window type's properties.

MFC SDI Application, how to change caption of menu item?

The whole day I am trying to solve this simple issue, but without any success.
I found a lot of hints in internet, but seems, that none of them is valid for my problem.
My issue is quite simple: I want to change the caption of a menue item while runtime
But it seems, that all solutions I found are very specific.
My requirements are this:
- it is a MFC application (VS2010)
- It is a SDI application, not MDI
- I want to change the caption of a main menu item (like "File"), not an entry of a submenue.
Because of main entry item, there is no ID for the menu item. Therefore solutions with ON_UPDATE_COMMAND_UI will not work!
My problems are:
- either the code I tried, is generating an assertion or exception
- or the function call returns with false
- or the function seems to work well, but I do not see any result (the caption is still unchanged)
Maybe I am using the wrong functions, or the wrong place for calling the functions.
Has anybody an example, which would work within my application pre-conditions?
Many, many thanks!
Richard
Windows cleverly hides the function to modify a menu under the arcane name of ModifyMenu. I hate it when they do things like that. Really makes me wish for Linux/Unix, with nice clear names like shmdt and mvwaddchnstr. Anyway, getting off my soap box for the moment, you'd call it something like this:
GetParentFrame()->GetMenu()->ModifyMenuW(1, MF_BYPOSITION, 0, L"New Item");
GetParentFrame()->Invalidate();

How To Make Page To Interact With Background Page?

My Chrome extension has a background page that execute script on current tab.
The script change elements on current tab by adding code to existing elements to call function 'myFunction' defined at background page when 'onClick' events occur.
The problem is that exception is thrown that 'myFunction' is not defined on current tab.
what is the best way to enable this interaction? to enable current page to go to function defined on background page?
Thanks in advance!
The background page is executed in an independent context, and thus its functions can't be directly executed in the currently opened tab.
What you need is a content script executed on all the tabs, that then communicates with the background page, using the message passing mechanism.
Without more information, it's difficult to help you more.
As mentioned in the first answer, "Without more information, it's difficult to help you more.", but for your second question it sounds like what you need is a reference to the function defined in your background page. This can be achieved with the getBackgroundPage function. The code looks like this;
var bgPage = chrome.extension.getBackgroundPage();
bgPage.myFunction();

calling validation on tab click ( jQuery-Validation-Engine )

I have set up the jQuery-Validation-Engine addon (https://github.com/posabsolute/jQuery-Validation-Engine) and it works great on the submit button.
However, since i invoked a tab-based interface, it doesn't really bring the user back to the proper tab with the error fields.
As a work around, i've decided its better to validate each tab when leaving to the next one (as it is a step-wise tab) so that the button click at the end will only 'really' need to correct any errors on the currently displayed tab.
I'm using a simple anchor to call some div swaps (using negative margins for content off-page).
I'd like to invoke the validation method to this as well.
Documentation says it can only be attached to a form element.
Any ideas?
Update- i ditched the tab idea and am now using one big form so this no longer really applies.
No support led to going after a different approach. No longer needed.

Core data dirty flag not being set

I have a core data document based cocoa app that is working well except for one slightly odd problem.
For some reason, if I make a change to any of my fields the menu/window don't seem to recognize it - ie. the red close button doesn't get the black 'dirty' indicator and the File/Save menu item isn't enabled. However, if I attempt to close the application (via command-Q), I do get the popup asking me if I want to save my changes.
It seems that the document's dirty flag is being set, but the window/menu items aren't reacting to it. I am curious as to where I might look to see why this might be the case. I suspect that it may have something to do with my window not knowing about my ManagedObjectContext...
The only slightly atypical behaviour is that my document's makeWindowControllers method has been overridden and I am adding my window controllers using a call to my document's [self addWindowController:xxx] method. My window controllers subclass from NSWindowController so I had to add my own instance variable to each window controller to hold the ManagedObjectContext, but I suspect that this isn't getting passed to the window/menu. Not sure what the normal pattern is here...
Anyway, any thoughts would be much appreciated. Thanks
From the description it sounds like your UI elements are not actually bound to the document itself. If so, then the UI elements are not observing the document and are not reacting to changes in the document. Check the bindings.
Thanks in part to TechZen, and also re-reading my own question (in particular, where I said "I suspect that it may have something to do with my window not knowing about my ManagedObjectContext") I started to look at the bindings for my WindowController subclass.
As it turned out, I hadn't bound the window outlet for the File's Owner to my actual NSWindow. As soon as I did that, the black dirty dot and the window's menus started behaving correctly.

in-place message in MFC?

Hi
If any one knows how to use in-place warning message in MFC could you share info.
Is there a way to use it or is there any control we can use directly in mfc.
In-Place warning message: A warning message with appropriate icon along with warning message, will be displayed with in the same dialog.
I found some info about in-place message in msdn
InPlace message in msdn glossary
Different messages
Please share information.

From your comment, it appears that you're referring to this as an in-place message:
Ironically, of course, that's labeled as the incorrect example on the MSDN page that you link to. It's specifically recommended that you provide more specific advice, such as securing the projector with a password so that the presentation is not visible to unintended viewers. Putting that aside, however...
This is quite easy to implement in MFC. It's done simply with two STATIC controls, one on the left that displays an icon (in this case, a warning triangle) and the longer one on the right that displays static text (the warning message itself). If you're using the dialog editor to create your window, it's a simple matter of dragging the two controls to the dialog window and arranging them accordingly. There isn't a single control that encapsulates this functionality, but it's silly to expect that there would be, considering that doing it with two separate static controls is already so straightforward.
To load built-in icons such as the warning triangle shown above, you can use the LoadStandardIcon function and specify IDI_WARNING as the icon name. The complete list of values is available here. Obviously you can load any icon of your choosing as well; just add it to your project's resources.
Since you will presumably want to display the warning message only when it's applicable, you will need to programmatically hide and show the two controls depending on action taken by the user in your dialog. The standard ShowWindow member function makes this a trivial task. Call it on the two static controls, passing SW_SHOW as its argument if you want the warning message to be visible. Otherwise, you can specify SW_HIDE to hide the control.
As an alternative to what you are trying to do; you could place your message in a dialog:
int nResult = AfxMessageBox("Save changes to Current Job?", MB_YESNO);
if (nResult == IDYES)
{
OnFileSave();
}
