hi,
i often have "Problem" with BMP as Resource under Fivewin (work with Xbase++ and HMG)
now i have figure out that those BMP have no DPI Setting (most i "save" from Windows PAINT)
when change to 96 x 96 DPI and "save" it work with Fivewin without Problem
but i have to change it manual using InfanView ...
Question : is there a API Way to change DPI of BMP

Thanks for sending the bmp files.
This is the way we can use these bmp files directly or as resource as it is, without any modifications.

RCDATA is 10
For AlphaBitmaps we have to use RCDATA. (better 10)
If your resource compiler complains that BITMAP file is not of a valid format, then change BITMAP to 10 (RCDATA) and try again.
When we specify RCDATA (10), the resource compiler reads the file and stores the contents as a string,
When FWH reads the resource, what all it gets is a string, which can be a pure text or binary data.
FWH ReadImage function checks if the data is a binary data and then if it is an image type and then what image type it is (bmp,ico,cur,jpeg,png,tiff,etc) and then reads it as an image and converts into hBitmap (in some cases it can be meta or other types.) We just leave all that headache to FWH and get back hBitmap (or pImage) or nil.
