问题 In older version of Borland C++Builder you used the Console Wizard to start off a Win32 program. That is now gone from XE5! How do I start?? 回答1: The wizard you are looking for is located at: File > New > Other ... > C++Builder Projects > Console Application However, the wizard dialog has been broken since XE2 and is still not fixed in the latest version (XE7 at the time of this writing). The dialog has a drop-down list to select a "Target Framework". If you set this to "None", you may get

I added following code in FormShow() of the TFormStart TFormStart::FormShow(TObject *Sender) { if (useOther) { FormOther

问题 I've dynamically linked libhunspell.dll (HunSpell) to my application. It works, but there is a dumb problem which I don't know why it happens. Even before I use LoadLibrary("path\\to\\libhunspell.dll"); to load it and use it, on the start of the application it attempts to load the library by itself. If I place the libhunspell.dll into the path where my main executable resides, it can load it, otherwise it reports an error, immediately after starting the application - This application has

To get the app back to work, plus remove the class declaration of the component is still necessary delete the WebFunctions.obj file. Note: Any declarations in .cpp file,

问题 I have an iOS static library (.a & .h file) and would like to know how to implement it into a C++ Builder project. The documentation cover's how to import a Java library in some detail but does not touch on a third party iOS library at all. Nor are there any blog posts or video's from Embarcadero about doing so. The closest post I have found is: Checking for an internet connection on mobile devices with Delphi XE5 However, it is not clear how to link in the .a file and then how to access the
