In ISWE 2.03, I was able to export the bitmap used by the other dialogs, then add a bitmap control and reference this bitmap.
In ISDev 7.0. the standard dialogs seem to have two overlapping text boxes; the text value of one of them reads something like "@10550, 10551;1;0;;0,128,128"
I tried duplicating this, but it displays the literal text, not a bitmap. I can't use the bitmap I was using in the ISWE, because it is a different bitmap; besides the overall look, the dimensions appear to be different.
Any pointers in the right direction will be appreciated...
