With XE 10.1 does anyone get "Cannot assign a TAppearanceObjectItem to a TAppearanceObjectItem" if you have a multidevice application with a listview on it set to dynamic appearance and you then create an Android View from the Master view. I am sure this must be a know issue but I am having trouble finding anything about it. Thanks

I've a problem with TScrollBox not showing scroll bars on OS X, works fine on Windows.

Tried running Samples\Object Pascal\Multi-Device Samples\User Interface\ControlsDesktop\ControlsDemo and get same problem. You may want to modify random position generation on line 353-354 of ctrlsdemofrm.pas to have smaller values, I set them to be 800 and 400.

I'm using RAD Studio 10 Seattle (Recharge)

Anyone else have this problem?

Since 10.1 Berlin when I click on "Menu->Run->Run" or enter a key which I had assigned via GExperts to the "Run"-Command it only functions at the first attempt, if I try it again, the command "build all" was executed instead. This worked in version 10 seattle. I have a project group with about 70 projects in it. Someone has seen this also? Thanks in advance, Harald

I have a calculated field that is editable, when the value changes it updates the underlying database field that it is calculated from, however as soon as I move to another cell (without posting) the value reverts to the old calculated value.  This is understandable, because the calculated field is still showing the previously calculated value.

How do I cause the calculated field to recalculate based on the current (edited) value before the record is posted?

Hi everybody.

I want to print something with Printer of "Microsoft Print to PDF" and file name of "myfile.pdf".  But I do not want to show any dialog box.

/* This is a code displaying PrintDialog and SaveDialog */

if ( PrintDialog->Execute() ) {

    Printer->BeginDoc();

    // some code

    Printer->EndDoc();

}

Is there anybody knows how to do this?

Thanks.

Wie kann ich mit 10.1 Berlin debuggen und nur in meinen eigenen Sourcen bleiben (kein Aufruf/Übergang in VCL/System oder sonstige  Module). Ich bin von DELPHI XE2/3 umgestiegen und habe das Problem, dass ein zeilenweises Debuggen praktisch nicht mehr möglich ist. Ich finde auch keinerlei Einstellungsmöglichkeiten in der IDE oder beim Projekt.

Danke für die Hilfe

I'm currently using XE7, and I have a project group with about a dozen VCL projects in it, some of them rather large.
When I have one of my projects selected as the active project and I click F5 to debug the application after I build the application, the IDE tries to rebuild all of the projects in the group, when it shouldn't be buildingany, since (1) nothing has been modified, and (2) I just built the project I want to debug.
This is causing me to lose quite a bit of time in my code / debug cycle. It is especially troublesome because my applications use compiler variables for conditional compilation and some units have to be rebuilt for specific projects. When the IDE tries to rebuild a project I don't have selected, it fails because a particular unit was not rebuilt. This happens despite the fact I have no inter-project dependencies defined.
I have recently discovered that if I hit F5 within 0.5 seconds after building my project, it runs without further rebuilds. If I wait any longer than that, it tries to rebuild the entire group, errors out because of the conditional compilation issue described above, and I have to start over.
Is this a known issue in XE7? Is it fixed in any later version? Is there anything I can do to fix it in XE7?

Situation: I need to save into the combobox two parameters, a String(user can see) and an int (user can't see).

How can I convert a String/int in TObject or, if it's possible, convert one of my classes(object) in TObject?

I've adapted the macro  EXPORT RELATIONSHIP INFO TO EXCEL v2.BAS in Data Architect - however the Model.Relationships object returns sub-type "relationships" in addition to the actual entity relationships.  I don't want to see these sub-type "relationships" in my list, but there isn't any property I can see that distinguishes sub-type "relationships" from identifying entity relationships.  How can I do this?

Hi, I have a DataSnap Rest Server created with Delphi Berlin and DataSnap Rest Client Module both in a local development without problem. I created one DLL with the wizard for IIS and the server is running and display the methods but when i want to create a DataSnap Rest Client Module with remote server i have a next problem:  

Somebody have a idea how to solve?? Thank´s

I'm developing a web browser with C++Builder 10.0 Seattle that uses a drawer as its master navigation, but the drawer does not overlap the web browser component. I've tried everything but cannot seem to get it working.

Hi,

I'm moving a Delphi application from the BDE to FireDac (and from Delphi 7 to Seattle, but that's another subject). This application uses a MSSSQL database.
I'm facing a problem related to the accentuated characters (like é, ä, â...).
In the BDE then langdriver was set to "Paradox 'intl'" in the native MSSQL driver. 

I don't know to solve this problem. Is there a parameter to adjust in the FDConnection? Or do I need to convert the data?

In RAD Studio 10.1 Berlin quite a few things has changed from previous version. In FMX there are a few previously published events that has now been changed to only be public.

I have a Multi Platform Project that uses a TStringGrid component and the OnDblClick event. When opening this project in Studio 10.1 I get warned that the Property OnDblClick does not exist.

The question is now how I can use the no longer published event?

(I must say that It's hard to understand why they haven't set mouse events to Published anymore. As far as I know most regular PCs and OSX machines doesn't have touch. A true Multi Target Project should be able to target these systems without hassle as they did in Studio 10 Seattle)

I am working on a Delphi program in XE7 that uses three ClientDataSets, each with its own TDBGrid on separate TTabSheets of a TPageControl.  When I use the scroll bars on the TDBGrids to change records I often get stopped with the message " Access violation at address ________ in module 'midas.dll'."  One suggestion on the net was to put "midas" in the USES section of my code, but the same thing happened.  Anyone know what's wrong?

I have a small code like this:

var

  rtv_in, rtv_out: ID3D11RenderTargetView;

  dsv_in, dsv_out: ID3D11DepthStencilView;

begin

  //... some code here to setup rtv_in and dsv_in;

  TCustomDX11Context.SharedContext.OMSetRenderTargetViews(1, rtv_in, dsv_in);

  TCustomDX11Context.SharedContext.OMGetRenderTargetView(1, rtv_out, dsv_out);  

after this line rtv_out and dsv_out returns nil. But if I use some other DirectX translation (other than Winapi.D3D11) with some changes (like using PID3D11RenderTargetView instead and etc); it works fine.

Am I using this wrong or is there a problem in the API translation?

Does anyone have any info on how to implement SCPI commands in Delphi? I need to capture data from a digital multimeter. Thanks.

I'm developing a mobile app using C++ Builder Berlin 10.1 which use a Jar library to scan barcodes. With Java2OP, I obtained a Delphi Bridge File to use the functions of the Jar. I translated it to C++ and include it to my project with the associated Jar. Here are my files:

When I tried to use the functions like this :

    TJATScanLib* scan = new TJATScanLib();
    _di_JATScanLibClass scanner = scan->JavaClass->init();

C++ Builder raised this link error :

Did I use the functions in the wrong way?
