问题 When using VirtualStringTree to add accessibility support it is required to include the unit VirtualTrees.Accessibility in the uses section. This works in Delphi. The equivalent of this in C++ Builder would be to include the #include "VirtualTrees.Accessibility.hpp" . But including the include file doesn't have any effect. I've traced the problem to the VirtualTrees.Accessibility.pas file and it executes a few lines of code to register the default accessibility provider in Delphi while this

问题 Now that the Microsoft Chromium Edge is final, is it possible to use it in Delphi or C++ Builder? As I understand it is based on a WebView2 component. Is there a component such as TWebView2 or will Embarcadero provide one? Is there an example how to host WebView2 in Delphi / C++ Builder? Is it enough to install the latest Edge version so the app can utilize it? There was an example for the older version - EdgeHTML - here: Using WebView (EdgeHTML) in Delphi / C++ Builder 回答1: You can use

问题 I'm maintaining the VirtualTreeView component for Delphi and C++Builder. With Delphi everything is okay but when I compile the packages with the C++Builder the code in the initialization part in the Delphi units is not called. Any ideas? 回答1: When a Delphi unit's initialization / finalization sections are not being called in a C++Builder project, it usually means the Delphi unit is not being linked into the final executable, typically because the C++ code is not directly referencing any code

问题 I have a pretty abnormal(IMHO) error that it's being raised whenever I try do a request to a SOAP service: Unmarshalling Error: unexpected element (uri:"http://www.domain.com/ws/servicename/", local:"dummyArg"). Expected elements are <{}dummyArg> The method that I'm calling has is defined as: function GetData(const dummyArg: WideString): Array_Of_Data; stdcall; I have little experience with SOAP therefore I'm this [ ] close to lose my mind, I couldn't find any useful information on this. Feel

问题 I am using C++ Builder to create a VCL form application. Right now I have a TFrame containing a bunch of components and it looks like this... I also have a button call "Add". Basically every time I press that Add button on the form, a new TFrame is added to it and below the previous one making something that looks like a table. And in order to add duplicates I have to rename the TFrame each time before it is created. int __fastcall TForm1::AddMapCells(void) { Num++; TFrame1 * MyFrame = new

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Here 'free' means no need to buy any license. As I know VCL comes from Borland C++ Builder which is a commercial IDE. MFC belongs to Microsoft Visual Studio. If I didn't buy any license of BCB or MSVS, could I complie the header files of those two libs and link them to my own application(free app, no commercial

问题 I'm new to using RAD Studio as I currently have to use it for this current project. What I am trying to do is call functions defined in a DLL file which I generated in Visual Studio in a RAD Studio C++ project . Following the advice from this question below Using Visual Studio DLL in Embarcadero RAD Studio XE? I have converted the C++ DLL file I have generated from Visual Studio to a supported file for RAD studio using their command: mkexp pub-sub-sample.a pub-sub-sample.dll I can verify that

问题 I am trying to pack some structs with Borland C++Builder (XE6) (in the future: bcc). I am using a library which uses the following construct to create structs: #ifdef _MSC_VER #define PACKED_BEGIN __pragma(pack(push, 1)) #define PACKED #define PACKED_END __pragma(pack(pop)) #elif defined(__GNUC__) #define PACKED_BEGIN #define PACKED __attribute__((__packed__)) #define PACKED_END #endif PACKED_BEGIN struct PACKED { short someSampleShort; char sampleByte; int sampleInteger; } structType_t;

问题 I have a TImage on a form in FMX (FireMonkey). I want to load a bitmap into the TImage at runtime, where the bitmap should have a transparent background defined by the first pixel's color in the bitmap. This color might be different from bitmap to bitmap. I know how to do this at design time, by using the MultiResBitmap editor for a TImage. However, I can't find any examples of how to do this at runtime. Do I have to do this manually (get the color of the first pixel in the bitmap, then
