Re: Embarcadero CoCreateInstance exception 0x40000015

This is a VC project but the code in the renderer.cpp might be informative.

Re: Embarcadero CoCreateInstance exception 0x40000015

You only need to call CoInitialize(NULL); once, like when your form loads the
first time...as long as you have not called CoUninitilize(); it should stay ok.

You probably should call CoUninitialize(); as your program closes.

Re: Embarcadero CoCreateInstance exception 0x40000015

Been years since i worked with COM but you may need to add

CoInitialize(NULL);

at the top of the code

Re: Win64 Sstand alone SQLite

Have you tried it without setting these setting to false to see if it makes a difference?

C++ Linker Link with Dynamic RTL = false
Runtime Packages - Link with runtime packages = false

Re: C++Builder IDE maximize

Arrange your IDE however you like, then click the "Save current desktop" button on the toolbar.
Name it something like "Default Layout 1" and then it will start up as you have set it. Note that
i am using older XE5 version but i assume the later versions have this also.

You make a new package in c++ and add the pas to it and install it as a item in your tool palette.

Re: Form not displaying correctly on Laptop

I tried this component and it works well. I do not know if it will work the way you want it to but it seems as it would. Just follow the instructions once you have made it into a package for install to your tool palette. If your form is sizeable with the mouse it should do what you need it to. https...

Re: Form not displaying correctly on Laptop

I had this problem once myself, the only option you have is to make your form smaller
if you have a laptop with an unusual resolution....as far as i know.

Re: [Android]BASS

Have you tried using

BASS_ChannelSetAttribute(str, BASS_ATTRIB_VOL, float(TrackVol->Position / 100.0));

or whatever version of that call that android uses.

BASS_SetVolume() changes the OS volume.
