Dynamically change custom print paper in C ++ Builder programming

Dynamically change custom print paper in C Builder programming

Due to the Delphi example in the Internet, I found some examples when I was written in CB.

So I have checked the information yourself, I'm afraid that the netizens also meet this situation when using programming.

I immediately passed.

Void __fastcall tform1 :: bitbtn1click (Tobject * Sender)

{

Char * ADEVICE, * ADRIVER, * APORT

Thandle DeviceMode;

PDeviceMode devmode;

INT Length, Width;

Length = 1400;

Width = 2410; // Setting the size unit of custom paper is 0.1 mm

Adevice = new char [100];

Adriver = new char [100];

Aport = new char [100];

/ / Get the printer

Printer () -> GetPrinter (Adevice, Adriver, Aport, DeviceMode);

// Get a PDEVMODE structure

DEVMODE = (_ DeviceModea *) GlobalLock ((void *) devicemode;

/ / Set the value that can be modified

DMFIELDS = devmode-> DMFIELDS | DM_PAPERSIZE

DMFIELDS = devmode-> dmfields | DM_PAPERLENGTH;

Devmode-> DMfields = devmode-> DMFields | DM_PAPERWIDTH;

/ / Set the value to modify

DEVMODE-> DMPAPERSIZE = DMPAPER_USER; / / Change Paper

DEVMODE-> DMPAPERLENGTH = Length;

DEVMODE-> DMPAPERWIDTH = Width;

// Test print

() -> begindoc ();

TextOut (Printer () -> Handle, 0, 0, "---------------", 17);

PRINTER () -> newPage ();

Textout (Printer () -> Handle, 0, 0, " , 18);

PRINTER () -> newPage ();

PRINTER () -> enddoc ();

}
