Question:
How do I add a TrueType font to Windows 95 in code?
Answer:
You should copy the file to the Windows\Fonts directory, then add
an entry to the registry key:
"Software\Microsoft\Windows\CurrentVersion\Fonts".
The entry will be the font name and the path (if different than the
Windows\Fonts directory). Once the registry entry is written, you
should make a call to the Windows API function AddFontRecource(),
then broadcast a system-wide WM_FONTCHANGE message. Finally, you
should make a call to the Windows API function RemoveFontRecource(),
to remove the resource lock on the font file, and broadcast a second
system-wide WM_FONTCHANGE message.
Here is an example:
// In the header file use:
// #include
// and
// TRegistry *reg;
NOTE: The WINGDING font is an example.
void __fastcall TForm1::Button1Click(TObject *Sender)
{
bool b = false;
b = CopyFile("C:\\Download\\WingDing.TTF","C:\\WINDOWS\\FONTS\\WingDing.TTF",b);
reg = new TRegistry;
reg->RootKey = HKEY_LOCAL_MACHINE;
reg->LazyWrite = false;
reg->OpenKey("Software\\Microsoft\\Windows\\CurrentVersion\\Fonts", b);
reg->WriteString("WINGDING(TrueType)","WingDing.TTF");
reg->CloseKey();
reg->Free();
AddFontResource("C:\\Windows\\Fonts\\WingDing.TTF");
SendMessage(HWND_BROADCAST, WM_FONTCHANGE, 0, 0);
RemoveFontResource("C:\\Windows\\Fonts\\WingDing.TTF");
SendMessage(HWND_BROADCAST, WM_FONTCHANGE, 0, 0);
}
