C++ ~ App Destructor cause build error?
Hi all
I downloaded a code example:
https://github.com/BlackBerry/presentations/tree/master/2012-BlackBerryJam-Americas/JAM09/BaDumTss
You will notice in the files app.cpp and app.h, the following lines in bold.
App.cpp
SoundPartyApp::SoundPartyApp() { // create the qml etc. mSoundManager = new SoundManager("sounds/"); } SoundPartyApp::~SoundPartyApp() { // Destroy the sound manager. delete mSoundManager; }
App.h
class SoundPartyApp: public QObject { Q_OBJECT public: // This is our constructor to setup our badumtss2 application SoundPartyApp(); // This is our destructor that frees the memory of the sound manager ~SoundPartyApp(); // more stuff here etc private: // The sound manager SoundManager *mSoundManager; };
I understand that this is with the old code, c ++. The new app.hpp which I use in Beta 3, so has a different 'virtual' destructor:
class SoundPartyApp : public QObject { Q_OBJECT public: SoundPartyApp(bb::cascades::Application *app); virtual ~SoundPartyApp() {} // etc }
The (new) ~ virtual SoundPartyApp() seems to conflict with the app.cpp function.
Do not know why.
I put comment function and now it works... but I guess now I'm not unallocating correctly the soundmanager of memory.
I can't seem to find useful discussions on how to get Beta 2 ~ beta3 destructive functions.
Any ideas?
If you want to move the main application code, just that:
virtual ~SoundPartyApp();
And then in the main application do all you need to do:
SoundPartyApp::~SoundPartyApp() { // do some important cleanup delete mSoundManager; }

Hello
I use LV 8.6 and Application Builder. My Labview vi uses some third party vi to control a linear motor. The vi works well not respected. Can I complie an exe without errors, but when I run the exe, (on the same PC), I get the below error. (Connect.vi is the third party VI used to start communication with the motor). In this case with my vi and vi example of a third. I also have an exe from one of the vi from the engine supplier that works.
On the error, I don't know why he mentioned NEITHER-488, I've never used (I don't think) so why it causes an error?
Thank you

help please...Hmm, that's strange. This means that the PER_PHONES_PK wrong a primary key constraint (it's the slightest error in the package per_phn_shd constraint_error procedure).
I don't know what could be wrong with that. The PER_PHONES_S sequence might have been rebuild or reset somehow?

Build error cannot find the distribution under construction
I had a similar problem like this thread.
http://forums.NI.com/T5/LabVIEW/build-error-can-t-find-distribution-being-built/TD-p/1462842/page/2
My old guard Installer and ask for copy of the installation is finish. Quite annoying because it takes so long to get there. Any advice would be appreciated. I've attached a screenshot of my error message.
You created this problem by running a build already install on your development computer. If you are distributing drivers with your installer you should NEVER run the installation program on the machine on which you build.
Here's what happens:
All software shops NOR where it was installed since in the Windows registry. When you initially installed it note where you install (DVD, network drive, etc.).
When you build an installer in TestStand will prompt for this location if it cannot find the original installation files (that is, if you take the DVD from the drive disconnected from the PC from the network, etc.)
What happened on this PC is you have to build a Setup program, and then you run this installer on the PC, and because the pilots were already present it replaced the path stored in the registry with the path where your Installer (e.g.) was C:\Temp\long path)
I'm guessing that you have now deleted this former Installer. That means that you have to re - run installers for ALL the software to, OR that you have installed on this machine so the registry is updated to point to the path of DVD or the network path.

Windows Live Photo Gallery causes the error Code: 0 x 80010108
I have a desktop XPS 8500 running Windows 7. Love it except for one thing: Windows Live Photo Gallery causes the error Code: 0 x 80010108. Yes, I x it down and go ahead and use my computer but like it to stop. I have google code and there are a number of fixes called there for him - even though they claim. But I was reluctant to download anything on sites I don't necessarily trust OR conform to change my registry to fix it. Can someone recommend a cure to my problem? I have confidence in this forum for more than 12 years and feel that you will not recommend something that might get me in trouble.
Thank you

Hi Bessie,
Thanks for the reply. I suggest you to uninstall Windows Live Essentials from the computer and update to the latest version. You can download it from the link http://bit.ly/GQ9tPI . Please disconnect all the external devices connected to the computer (printers, external hard drives, flash drives) and do not have any CD/DVD in the drive while following the steps.
Answer please if you have any questions.
