FindResource (Compact 2013)
3/28/2014
This function determines the location of a resource with the specified type and name in the specified module.
Syntax
HRSRC FindResource(
HMODULE hModule,
LPCWSTR lpName,
LPCWSTR lpType
);
Parameters
- hModule
Handle to the module whose executable file contains the resource. In Windows Embedded Compact, this cannot be set to NULL.
- lpName
Pointer to the name of the resource. For more information, see the Remarks section.
lpType
Pointer to the resource type. For more information, see the Remarks section. For standard resource types, this parameter can be one of the following values.Value
Description
RT_ACCELERATOR
Accelerator table
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 Value
A handle to the specified resource's info block indicates success. To obtain a handle to the resource, pass this handle to the LoadResource function. NULL indicates failure. 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.
The lpName parameter does not support the resource ID zero - that is, FindResource(h, 0 ,t) will not work as expected.
An application should reduce the amount of memory required for the resources by referring to them by integer identifier instead of by name.
When you are finished using an accelerator table, bitmap, cursor, icon, or menu, you can release its associated memory by calling one of the functions in the following table.

The system automatically deletes these resources when the process that created them terminates, however, calling the appropriate function saves memory and decreases the size of the process's working set.
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 |
Description |
|---|---|
Loads and formats a message-table entry. |
|
Loads an accelerator table. |
|
Loads a bitmap resource. |
|
Loads a cursor resource. |
|
Loads an icon resource. |
|
Loads a menu resource. |
|
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.
String resources are stored in sections of up to 16 strings per section. The strings in each section are stored as a sequence of counted (not null-terminated) Unicode strings. The LoadString function will extract the string resource from its corresponding section.
