In any case to have an onLoad function in qml appending NavigationPane?

I'm new to Blackberry 10 dev. So I was wondering what is the best way to do that I get no clear answer dev documentation.

What I want is to start a separate view in my application from a navigation screen. The new page will then create an http request and update the UI based on the output.

The best way seems to use the NavigationPane and add view qml. But how do I invoke a C++ function when placed on the stack? Something similar to android onActivityCreated() in Fragments. There are the docs for example Http, but the program started the HTTP from the legacy of the QObject constructor. How I have a function that is executed as the new qml is added to the navigation as a stack

 // navigationpane.qml

NavigationPane {
    id: navigationPane
    Page {
        Container {
            Label {
                text: "First page"
            }
        }

        actions: [
            ActionItem {
                title: "Next page"
                ActionBar.placement: ActionBarPlacement.OnBar
                onTriggered: {
                    var page = pageDefinition.createObject();
                    navigationPane.push(page);
                }

                attachedObjects: ComponentDefinition {
                    id: pageDefinition;
                    source: "secondpage.qml"
                }
            }
        ]
    }
    onPopTransitionEnded: { page.destroy(); }
}

Most of the QML objects have a creationCompleted signal, so you can set an onCreationCompleted: {...} to do what I think that you ask for.

Note that it runs only when the thing is first created, well... If you reuse (hide but not destroy it, and the later make visible again) you'll need something else. Some components have relevant signals for this (for example onOpened, I think, for dialogue) but for others, you need make your own signal (which is trivial to do well).

Gmail said "some important features may not work in this version of your browser, if you have been directed to the basic HTML version. Upgrade to a modern, like Google Chrome browser. Try the standard version in any case. "

When I visit Gmail using Firefox version 8.0 (running w7) I get this message: "important features may not work in this version of your browser, if you have been directed to the basic HTML version. Upgrade to a modern, like Google Chrome browser. Try the standard version in any case. "

When I click "Try Standard Version Anyway" it works, but for some reason, Gmail is say that Firefox 8.0 is not a modern browser. Also, whenever I visit Gmail, he returned to the basic HTML version... ba.

It seems that Google is trying to make you switch to Chrome. I would stick with Firefox, but Gmail is an important part of my browsing...

I found the solution... browsing around, I found this link:

When to call DSDisposeHandle when you have a DLL function acting as a dynamic data DS source extensible?

Hello

I have a dynamic function DLL acting as a data source within a LabVIEW application (see attachment) - I use DSNewHandle to dynamically allocate an array 2D handle storage via the Manager memory LV for arrays of arbitrary in application size data. I had assumed that these blocks of memory would be willing (Magic) when appropriate by the LabVIEW built in blocks that are sitting downstream, however, is not the case for treatment and the system LabVIEW memory usage continues to increase until you quit LabVIEW environment (not just if the offending application is stopped or closed).

So my question is how and where to mop up the table used for buffers in the treatment of the application of the chain and how do I know when the buffers are really exhausted and not be re-used downstream (for instance two 2D paintings are first grouped into a 2D complex table by the re + im at the operator complex labview - is data memory out of this totally different stage of entries or is - a) modified version of the entry tables - if they are totally different and 2D to entry tables are not wired in all other blocks why the operator not have input data banks?)

Maybe Im going to this topic in the wrong direction have the DLL data source dynamically allocates space data tables? Any advice would be welcome

Concerning

Steve

So instead of doing:

DLLEXPORT int32_t DataGetFloatDll(... , Array2DFloat ***p_samples_2d_i, ...)
{
    ...

    if ( p_samples_2d_i )
    {        // *p_samples_2d_i can be non NULL, because of performance optimization where LabVIEW will pass in the same handle        // that you returned in a previous call from this function, unless some other LabVIEW diagram took ownership of the handle.        // Your C code can't really take ownership of the handle, it owns the handle for the duration of the function call and either        // has to pass it back or deallocate it (and if you deallocate it you better NULL out the handle before returning from the        // function or return a different newly allocated handle. A NULL handle for an array is valid and treated as empty array.
        *p_samples_2d_i = (Array2DFloat **) DSNewHandle( ( sizeof(int32_t) * 2 ) + ( sizeof(float) * channel_count * sample_count ) );

        // Generally you should first try to insert the data into the array before adjusting the size        // the most safe would be to adjust the size after filling in the data if the array gets bigger in respect to the passed in array        // and do the opposite if the adjusted handle happened to get smaller. This is only really important though if your C code can        // bail out of the code path because of error conditions between adjusting the handle size and adjusting the array sizes.        // You should definitely avoid to return from this function with the array dimensions indicating a bigger size than what the        // handle really is allocated for, which can happen if the array was resized to a smaller size and you then return because of errors        // before adjusting the dimension sizes in the array.         ........        (**p_samples_2d_i)->Rows = channel_count;
        (**p_samples_2d_i)->Columns = sample_count;
    }

    ...}

You should do:

DLLEXPORT int32_t DataGetFloatDll(... , Array2DFloat ***p_samples_2d_i, ...)
{
    ...
    MgErr err = NumericArrayResize(fS /* array of singles */, 2 /* number of dims */, (UHandle*)p_samples_2d_i, channel_count * sample_count);
    if (!err)
    {        // Fill in the data somehow
       .....       

        // Adjust the dimension sizes        (**p_samples_2d_i)->Rows = channel_count;
        (**p_samples_2d_i)->Columns = sample_count;
    }

    ...}

How to replace a bad IDE disk with a USB Flash drive system - and have all the functionality of XP Pro SP3

How to replace a bad IDE disk with a USB Flash drive system - and have all the functionality of XP Pro SP3

Given a PC without hard disk...

How can you use a flash drive instead?

So, indeed, the USB key works as an SSD...

I saw online options that gives partial functionality of the system... and an option that is more than $100 (more than the system's worth)...

None of these options are acceptable in the circumstances.

It is an effort to create a machine for a particular use, built from a recycled pc for which hard drive was removed and destroyed by the original owner...

The criterion is that it must work just like it was a mechanical drive running xp pro sp3 with all updates, etc...

Thanks for any help.

You can not install XP on a Flash as his unsupported drive. Your only two options are a traditional hard drive or Solid State Drive (SSD).

In any case to stop WMP using identification tags and simply use file names?

I do not use DVD or CD more - for the most part, torn from my PC and streaming via WMP on my PS3/TV

Only problem I have, is that I used the folder & file naming to organize all my media

in fact I only use the view file on WMP

but uses WMP ID tags where date and/or filename if not - that seems messy

In any case to stop WMP using identification tags and simply use file names?

Or at least WMP can be used to remove unwanted tags - mainly video?

I tried to remove them one at a time that "seems" to work until I have re-catalog and tags miraculously reappear?

Tri-pour those who have the same problem - I used Windows to remove the ID tags

Open the window containing the media files > search * to reveal all the files (save you open folders one at a time)

Folder view > Details

Right-click on the column details bar / > more >

Add the 'title' column (this will display the titles (tags) > OK)

Sort by title window will consolidate all the videos that have set the title/tags

Select all video files with titles

Right click > properties > Details >

Choose "Remove properties and personal information" > OK

Choose "remove after this file properties.

Check "Title" (multiple values) - careful not to tick/delete other important tags

Ok

Take a few minutes depending on the number of files

Sorted

WMP shows now all my media by filename

Try installing Acrobat Pro XI and the installer says I already have a more functional version installed. What I installed is XI Acrobat Standard, but I want to install Acrobat Pro 11. I owe unitstall Standard for install Pro?

I try to install Acrobat Pro XI, but the installer says I already have a more functional version installed. What is installed on my PC is Acrobat XI Standard, which I don't consider to be a more functional version. What I actually need to uninstall the version Standard in order to be able to install the Pro version?

Ugh! I have PitStop Pro 12 installed in Acrobat Standard XI as a 3rd party plug-ins. Do you know by chance that will survive the uninstalling XI standard and installed in XI Pro?

If this isn't the case, then I have to turn off before the Standard uninstall, reinstall it after the installation of Pro and then re-enable it.

Even though I hate the answer you provided, thank you to answer and do it very quickly.

In any case about 512GB cap on virtual disks? / DRS issue?

Hi all
My first question is this:
I have a San with about 1.7 TB Free however when I go to create virtual disks for one of my Vm It CAPS he died in 512 GB of space, is anyway around this hairstyle? other then extended partitions within windows using with 2 VMDK?
My second question is when you have activated DRS, but value manual for all your machines, there is in any case to prevent it from asking which server you want to start the virtual machine on every time you have to start the virtual machine. Even when I have the virtual machine created on one of the ESX servers in the cluster and go to start from this server, he always asks what server I wish on the VM with.

(1) Yes, but not after you create the file system on the LUN - choose a new size of block to the VMFS is a destructive operation.

(2) it is normal, expected behavior. His request because potentially the best server to start the virtual machine on may not be the current.

My folders disappeared when 10.6.8 OS10.11.3. In any case, to get this stuff back in folders rather than a long list of files?

Where they disappeared?

Some changes that may be what you watch:
- All of my files - this is the search folder that searches all your files in your home and presents them in one place. They were not moved, they are displayed just like they are.
- Framed by default - the sidebar returns the values by default for all folders that you placed there will need to be added again.
Your files are stored inside your folder into subfolders such as Documents, movies, pictures, etc. They are all should still be there. You can add one of these folders to the sidebar by dragging them there, or you can use the tab of the sidebar in the Finder preferences.

You can access your file in the Finder with cmd-shift-h (menu go).

Microsoft had a band, probably not my music a little... In any case, it is the second shortcut of Microsoft which is supposed to take me to the "Windows 7 Compatibility Center.

I won't be here but Microsoft seems very happy sending me on the prosecution of the wild goose, and here I landed! I didn't even know that Microsoft had a band, probably not my music a little... In any case, it is the second shortcut of Microsoft which is supposed to take me to the "Windows 7 Compatibility Center. The first, in the Windows help sent me to http://windows.microsoft.com/en-us/windows/support#1TC=windows-7. Not a mention of the word "compatibility" on the page anywhere. Then, enter 'compatibility' in the search for support and here is the result, looks promising. https://www.microsoft.com/en-us/search/result.aspx?q=compatibility. But no, I click on the first result that says Microsoft compatibility Center. Even what seems to be the correct web address, microsoft.com /compatibility and it takes me here http://www.microsoft.com/microsoft-band/en-us/support/hardware/microsoft-band-system-requirements. I give up!

Hi André,.

Please keep us updated.

Unfortunately, the center of compatibility Windows has actually retired. To find out if any program that works with Windows 10 or not, you can check with the developer to program on the compatibility of its operating system. In addition, when you migrate to Windows 10 from a previous version of Windows, you are informed about programs that may not work with Windows 10. However, you can try to install these programs in compatibility mode and check.

Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.
