Function Reference


Determines the location of a resource with the specified type and name in the specified module

#include <WinAPIRes.au3>
_WinAPI_FindResource ( $hInstance, $sType, $sName )


$hInstance Handle to the module whose executable file contains the resource.
A value of 0 specifies the module handle associated with the image file that the operating system used to create the current process.
$sType The type of the resource. This parameter can be string or integer value.
$sName The name of the resource. This parameter can be string or integer value.

Return Value

Success: Handle to the specified resource's information block.
To obtain a handle to the resource, pass this handle to the _WinAPI_LoadResource() function.
Failure: 0, call _WinAPI_GetLastError() to get extended error information.


If the first character of the string of the $sName or $sType parameter 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.

To reduce the amount of memory required for a resource, an application should refer to it by integer identifier instead of by name.

An application can use _WinAPI_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 _WinAPI_LockResource().
