Download Heap allocation class File #9482. It has NumToLong method you can use.

oHeap = NEWOBJECT("heap", "clsheap.fxp")
lcRect = ;
	oHeap.NumToLonf(10) + ;
	oHeap.NumToLonf(0) + ;
	oHeap.NumToLonf(100) + ;
	oHeap.NumToLonf(100) 
...
oHeap = Null

This class has also some other usefull features for Windows API programming in VFP.

>Hi to all
>
>I am using a dll (_ISource30.dll) from www.smalleranimals.com. One of the functions of this DLL is to write text on an image.
>
>A number of parameters are passed to the function. One of them is by reference and consist of 4 values (bounding rectangle for the text). The only way according to me is to pass them as values within an array. I cant get the function to draw text. The developers assured me that it is working.
