C++ Builder: String MyString; What does it initialise to at declaration?

$
0
0

Trivial I know but:

I have got into the habit of using

// I use the following to ensure an empty string value...

String MyString = "";


But if I do not set an initial value, does String automatically create an empty string?

// Not setting an initial value, so is it filled with random stuff or empty?

String MyString;

Or does it do random (and often dangerous) like

// Using int without a default

int MyInt;

Yet

// Using int with a default causes a compiler warning that the value is never used!

int MyInt = 0;

Error when deploying an iOS ipa

We've been having an exorbitant number of issues trying to deploy an app for iOS. We were able to successfully create a build in September, but needed to make some adjustments for IPv6 compatibility. Now when we try to create an iOS Application Store/Release deployment, we get the following returned in the Messages window:

[PAClient Error] Error: E0776 2017-10-27 15:14:03.181 xcodebuild[1216:81669] [MT] IDEDistribution: -[IDEDistributionLogging _createLoggingBundleAtPath:]: Created bundle at path '/var/folders/d_/1k9k2tf93qn6mxc0v0g4y0440000gn/T/GQMobile_2017-10-27_15-14-03.180.xcdistributionlogs'.

No ipa file is generated on the Windows machine running Delphi Tokyo 10.2 Version 25.0.27659.1188, and the ipa file that is output into the PAServer\scratch-dir\[user]-[mac profile] directory on our Mac is not usable as a deployment build (the XCode Application Loader won't recognize it as a viable ipa). We are currently using XCode 9.0 Beta 5 (9M202q) on the Mac. We could really use some help getting this issue resolved. Our Android build went out a month ago just fine, but we've been struggling to get the iOS build out.

A question for converting existing projects.

Hi,

I am working for a major Software house which is developing executables for win64 platform for the last few years.

We now have about 400 executables with Delphi (Pascal) and we need to make them a little bit more attractive (modernize them) and make them available via the Internet using any browser that supports html.

Our program is a suite, we are working with Delphi Tokyo 10.2

We are not seeking for magical solutions, we know that we need to re-write part of our code but I was hoping that you give us some light or any ideas for which path we can follow to make this happen.

I am at your disposal for any further information you may need.

Regards

Problems with creating Firemonkey Style

Hello to all,

I'm trying to create a style for the Fmx :: TListBoxItem class.  I have inserted a rectangle as a base (ListArtItemsRecBase) to get the effect you see in the figure.

But doing so I blocked the events associated with the TListbox that will contain these items

If ListArtItemsRecBase.visible = false is all working properly.

How can I reactivate events without disabling ListArtItemsRecBase?

Thank you all for the help

Tokyo 10.2 Android edit box problem when displaying virtual keyboard

$

Since upgrading from XE10 to XE10.2 I have a problem that all my edit boxes in my app no longer move above the virtual keyboard.

However, on iOS it works just fine!

I'm using the code to move the vertical scroll box up to display the edit box just above the keyboard.

I will be trying to reinstall XE10 to make sure that I'm not shipping out an inferior product on Google's Play store.

Am I the only one who is having this problem? Does anyone know what to do?

Iot.Family.BluetoothLE.pas -- Can't debug IoT BLE

$
0
0

The LifeTrak sample for LifeTrak can't detect/discover the Lifetrak device even with it paired.

For this (or any similar BLE) application, Iot.Family.BluetoothLE.pas is needed to debug with any hope of completing a real application.

Iot.Family.BluetoothLE.pas is not provided in version 10.2 so there is little hope of making progress with BLE IoT development.

Is there an update (or other) support coming to make it possible to debug these BLE/IoT samples and other applications ?

Lack of working cross platform IDE -- BT, BLE , No support after being promised there would be support post 10.2

$

Our projects have been stuck for months, not even a reply to email requests for status update. Waiting for working bluetooth  so we can integrate sensors and other external devices using BT and/or BLE. And all of this after conference call where support was promised. Is this product dead as a cross platform solution ? Is it just there is no support for bluetooth external device ? Did the new Android multiple active apps updates totally break the graphics framework  and the product is dead ? The lack of progress and support makes it look like this is the end of the line for this environment as a useful tool. Is anyone able to interface or use generic BT or BLE devices using Delphi 10.2 ?   While the ability to do rapid UI is interesting, it is very limiting to not be able to use BT without extensive work around or limited functionality. If you need to have a professional Android UI and low level interfaces what IDE supports rapid product development so you can actually deploy products ?    Accept As Answer

Detecting Callstate on phone

$

Hi

A customer needs to see if an employee is busy on the phone (IOS/Android) before trying to call them.

I am looking for a way to monitor callstates on a device, and have tried the example in the Delphi Cookbook by Daniele Teti and also this example:

http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Mobile_Tutorial:_Using_the_Phone_Dialer_on_Mobile_Devices_(iOS_and_Android)

However, none of them works, at least not on my Samsung S7 phone, I can get carrier information end more, but no callstates.

Have anybody gotten the example to work, or have other suggestions on how I can solve this problem?
