FindResource
The FindResource
function determines the location of a resource with the specified type and name
in the specified module.
HRSRC FindResource(
HMODULE hModule, |
// resource-module
handle |
LPCTSTR lpName, |
// pointer to
resource name |
LPCTSTR lpType |
// pointer to
resource type |
); |
|
Parameters
hModule
A handle to
the module whose executable file contains the resource.
A value of
NULL specifies the module handle associated with the image file that the
operating system used to create the current process.
lpName
Specifies the
name of the resource. For more information, see the Remarks section.
lpType
Specifies the
resource type. For more information, see the Remarks section. For standard
resource types, this parameter can be one of the following values:
Value |
Meaning |
RT_ACCELERATOR |
Accelerator
table |
RT_ANICURSOR |
Animated
cursor |
RT_ANIICON |
Animated
icon |
RT_BITMAP |

RT_CURSOR |
Hardware-dependent
cursor resource |
RT_DIALOG |

RT_FONT |

RT_FONTDIR |

RT_GROUP_CURSOR |
Hardware-independent
cursor resource |
RT_GROUP_ICON |

RT_ICON |
Hardware-dependent

RT_MENU |
Menu

RT_MESSAGETABLE |
Message-table

RT_RCDATA |
Application-defined
resource (raw data) |
RT_STRING |
String-table

RT_VERSION |
Version
resource |
Return Values
If the
function succeeds, the return value is a handle to the specified resource s
info block. To obtain a handle to the resource, pass this handle to the LoadResource
If the
function fails, the return value is NULL. To get extended error information,
call GetLastError
Remarks
If the
high-order word of the lpName or lpType parameter is zero, the
low-order word specifies the integer identifier of the name or type of the
given resource. Otherwise, those parameters are long pointers to
null-terminated strings. If the first character of the string is a pound sign
(#), the remaining characters represent a decimal number that specifies the
integer identifier of the resource s name or type. For example, the string
#258 represents the integer identifier 258.
An application
should reduce the amount of memory required for the resources by referring to
them by integer identifier instead of by name.
An
application can use FindResource to find any type of resource, but this
function should be used only if the application must access the binary resource
data when making subsequent calls to LoadLibrary
To use a
resource immediately, an application should use one of the following
resource-specific functions to find and load the resources in one call:
Function |
Action |
FormatMessage |
Loads and
formats a message-table entry. |
LoadAccelerators |
Loads an
accelerator table. |
LoadBitmap |
Loads a
bitmap resource. |
LoadCursor |
Loads a
cursor resource. |
LoadIcon |
Loads an
icon resource. |
LoadMenu |
Loads a
menu resource. |
LoadString |
Loads a
string-table entry. |
For example,
an application can use the LoadIcon function to load an icon for display
on the screen. However, the application should use FindResource and LoadResource
if it is loading the icon to copy its data to another application.
