Hi all. How do i add several EXISTING bmp files (which i have on
my hard disk) into resource file named "MyResources.res" using
the Builder C++ 4.0 Image Editor? I searched in all the options
of the Image Editor and i did not find any way to add existing
bitmaps into the resource file, i also wasn't able to copy-paste
my bitmaps into the resource. Can someone please help me and
tell me how to do that?

Thanks!
Ulla

You can't using the image editor. Instead, create a MyResources.rc file
with the declarations of your bitmaps and then compile that file into a
..res file using brcc32.exe.

something like:

..rc
#define ID_BMP1 1001
#define ID_BMP2 1002
...

ID_BMP1 BITMAP "Bitmap1.bmp"
ID_BMP2 BITMAP "Bitmap2.bmp"
...

Then compile into a .res

brcc32 -32 MyResources.rc

Thanks Michel, that is exactly what i did at last, and it's
working very well, i used the instructions from this page:

http://www.bcbdev.com/faqs/faq52.htm

which is very similar to what you asked me to do.

But now i have some "small" problems -

On my form i having TImage which have it's 'Stretch' set to
'true', when i use this code then everything is good and i
can i see the whole image on the diaplay -

Image1->Picture->Bitmap->LoadFromResourceID( (int)HInstance, ID_BITMAP1 );

But if i use this code then i see on the display only pasr of
the image (the upper left side of it) -

Graphics::TBitmap *TestBmp = new Graphics::TBitmap();
TestBmp->LoadFromResourceID( (int)HInstance, ID_BITMAP1 );
Image1->Canvas->Draw( 0, 0, TestBmp );

Why?

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Also i don't understand why when i use this code there are so
many flickerings on the display -

Graphics::TBitmap *TestBmp = new Graphics::TBitmap();

for ( int i = 0; i < 2000; i++ )
{
TestBmp->LoadFromResourceID( (int)HInstance, ID_BITMAP1 );
Image1->Canvas->Draw( 0, 0, TestBmp );
Application->ProcessMessages();
TestBmp->LoadFromResourceID( (int)HInstance, ID_BITMAP2 );
Image1->Canvas->Draw( 0, 0, TestBmp );
Application->ProcessMessages();
}

What do i do to stop them?

Thanks!
Ulla

The Stretch property will only have influence during the
load of a file, not while drawing on the canvas.

Application->ProcessMessages();
TestBmp->LoadFromResourceID( (int)HInstance, ID_BITMAP2 );
Image1->Canvas->Draw( 0, 0, TestBmp );
Application->ProcessMessages();
}

First you could change that to:

Graphics::TBitmap1 *TestBmp = new Graphics::TBitmap();
Graphics::TBitmap2 *TestBmp = new Graphics::TBitmap();

TestBmp1->LoadFromResourceID( (int)HInstance, ID_BITMAP1 );
TestBmp2->LoadFromResourceID( (int)HInstance, ID_BITMAP2 );

for ( int i = 0; i < 2000; i++ )
{
Image1->Canvas->Draw( 0, 0, TestBmp1 );
Application->ProcessMessages();
Image1->Canvas->Draw( 0, 0, TestBmp2 );
Application->ProcessMessages();
}

delete TestBmp1;
delete TestBmp2;

You could also try:

for ( int i = 0; i < 20; i++ )
{
Image1->Canvas->Draw( 0, 0, TestBmp1 );
Image1->Update();
Sleep(150);
Image1->Canvas->Draw( 0, 0, TestBmp2 );
Image1->Update();
Sleep(150);
}

Both don't flicker here.

I tested your both your examples and i can see lot of flickers
in the two of them, in your second example i removed the Sleep
command and did the loop untill 2,000 becouse i don't want
any delays in the display, i need it for a fast graphics at
real-time. When i say Flickering i mean that the switch between
the two images in not smooth, is not plane, when i run this code
i see lot of bright lines comming very fast up and down on the
image, i have 2 bmp files with a blue background, the first have
one red ball at one corner of the image, and the other have a
yellow ball on another corner, when i switch this images very
fast i expect to see one single smooth blue background with 2
balls in it's 2 corners, when i run it the blue background looks
very smooth and nice but the balls are flickering a lot and have
many bright lines running on them.

Thanks, Ulla
