FindResource info  Overview  Group

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

Bitmap resource

RT_CURSOR

Hardware-dependent cursor resource

RT_DIALOG

Dialog box

RT_FONT

Font resource

RT_FONTDIR

Font directory resource

RT_GROUP_CURSOR

Hardware-independent cursor resource

RT_GROUP_ICON

Hardware-independent icon resource

RT_ICON

Hardware-dependent icon resource

RT_MENU

Menu resource

RT_MESSAGETABLE

Message-table entry

RT_RCDATA

Application-defined resource (raw data)

RT_STRING

String-table entry

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 function.

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 and LockResource.

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.
