LScreenCapture::CaptureFromEXE

#include "ltwrappr.h"

virtual L_INT LScreenCapture::CaptureFromEXE(pszFileName, nResType, pResID, bCaptureByIndex, clrBackGnd=RGB(0,0,0))

L_TCHAR * pszFileName;	/* filename to capture from */
L_INT nResType;	/* resource type to capture */
L_TCHAR * pResID;	/* Resource ID to be captured */
L_BOOL bCaptureByIndex;	/* flag that indicates whether pResID is an index or a resource ID */
COLORREF clrBackGnd;	/* background color to be used for icons */

Captures an image from the specified resource, stored in an EXE or DLL, into the associated class object's bitmap.

Parameter	Description
pszFileName	Character string containing the name of the exe (or dll) from which the resource should be captured.
nResType	Specifies the type of resource to capture. Possible values are:
	Value	Meaning
	RESTYPE_BITMAP	capture a bitmap resource
	RESTYPE_ICON	capture an icon resource
	RESTYPE_CURSOR	capture a cursor resource
pResID	Specifies the index of the resource to capture. You can use MAKEINDEX or MAKERESOURCEID macros to convert the resource ids to strings.
bCaptureByIndex	Flag that indicates whether pResID represents an index or a resource ID. Possible values are:
	Value	Meaning
	TRUE	pResID is the index position of the requested resource.
	FALSE	pResID is the resource ID of the requested resource.
clrBackGnd	Background color for icons.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
