Description
This method loads a bitmap from the return value of a codeblock. The codeblock return value must be a string that contains a valid bitmap. The bitmap returned from the codeblock must also contain a BITMAPFILEHEADER structure or it is ignored.
The BITMAPFILEHEADER structure is a standard Windows structure. Please refer to the Windows SDK reference for more information.
Due to the 64K size limit of strings in a 16 bit application, the size of a bitmap loaded via this method must be less than 64K when using the RP2/16 runtime.
Example
// Load a bitmap from a codeblock
// that references a DBF field
bCodeBlock:={|| mytable->bmpfield}
