How to use resource files

Here's how to compile the cursor and sound as a resource into an executable file, and how to use it.

The first step: Build an rc file.

For example: Zpg.rc, the contents are as follows:

Demhint WAVE D:\Zpg2000\Res\DemHint.wav

Printtype BITMAP D:\Zpg2000\Res\PrintType.bmp

Arrowdown BITMAP D:\Zpg2000\Res\ArrowDown.bmp

Arrowup BITMAP D:\Zpg2000\Res\ArrowUp.bmp

ZoomIn CURSOR D:\Zpg2000\Res\ZoomIn.cur

Zoomout CURSOR D:\Zpg2000\Res\ZoomOut.cur

One of the first behavior resource names, the second behavior resource type, and the third behavior is a filename that exists.

Step two: Compile this file.

>BRCC32 zpg.rc

BRCC32.exe in the/borland/c++ builder6/bin/directory,

Compiled into a resource file Zpg.res

Step three: Declare the use of resources in the program

Add the #pragma resource "*.DFM" statement to the cells in your program that you want to use these resources

#pragma resource "zpg.res"

Sometimes you need to add #pragma package (smart_init)

or add to the project Master CPP file

Useres ("Zpg.res");

How do you finally invoke this resource? See:

Call Bitmap:

Graphics::tbitmap *pbitmap=new Graphics::tbitmap;

Pbitmap->loadfromresourcename ((unsigned int) hinstance, "Printtype");

Play Sound:

PlaySound ("Demhint", Hinstance,snd_resource);

To change the cursor:

Screen->cursors[crzoomin]=loadcursor (hinstance, "zoomin");

Crzoomin is a custom cursor constant that is customarily a >0 number, whereas a system-defined general <0

Paintbox->cursor= (tcursor) crzoomin;

Application->processmessages (); Make sure the cursor changes immediately

Attention:

Resource files are only useful at design time, and when compiled, the resources are compiled into executables, so the program is distributed without having to carry resource files.
