The UpdateResource function adds, deletes or replaces a resource in an executable file.
hUpdateFile
Specifies an update handle. This handle is returned by the BeginUpdateResource function.
lpszType
Points to a null-terminated string that specifies the resource type to be updated. This parameter may also be an integer value passed to the MAKEINTRESOURCE macro, or one of the predefined resource types shown in the following list:
| Value | Meaning |
| RT_ACCELERATOR | ||
| Accelerator table | ||
| RT_BITMAP | ||
| Bitmap resource | ||
| RT_DIALOG | ||
| Dialog box | ||
| RT_FONT | ||
| Font resource | ||
| RT_FONTDIR | ||
| Font directory resource | ||
| RT_MENU | ||
| Menu resource | ||
| RT_RCDATA | ||
| User-defined resource (raw data) | ||
| RT_STRING | ||
| String-table entry | ||
| RT_MESSAGETABLE | ||
| Message-table entry | ||
| RT_CURSOR | ||
| Hardware-dependent cursor resource | ||
| RT_GROUP_CURSOR | ||
| Hardware-independent cursor resource | ||
| RT_ICON | ||
| Hardware-dependent icon resource | ||
| RT_GROUP_ICON | ||
| Hardware-independent icon resource | ||
| RT_VERSION | ||
| Version resource | ||
lpszName
Points to a null-terminated string that specifies the name of the resource to be updated. This parameter may also be an integer value passed to the MAKEINTRESOURCE macro.
IDLanguage
Specifies the language ID of the resource to be updated.
lpvData
Points to the resource data to be inserted into the executable file. If the resource is one of the predefined types, the data must be valid and properly aligned. Note that this is the raw binary data stored in the executable file, not the data provided by LoadIcon, LoadString, or the other resource-specific load functions. All data that contains strings or text must be in Unicode format; lpvData must not point to ANSI data.
If lpvData is NULL, the specified resource will be deleted from the executable file.
cbData
Specifies the size of the resource data at lpvData.
If the function is successful (the resource was added to, deleted from, or replaced in the executable file) the return value is TRUE. Otherwise, the return value is FALSE. Use the GetLastError function to obtain extended error information.
An application must use the EndUpdateResource function to complete the resource update process.
The UpdateResource function may be used as either a wide-character function (where text arguments must use Unicode) or an ANSI function (where text arguments must use characters from the Windows 3.x character set installed).
