putfile() not working?

[Nigel Gomm]

if putfile() and commondialog.showsave() start objecting that the filename doesn't exist

it's because the built-in anti-ransomware feature in windows control panel is switched on (for that folder).

(please don't ask how long it took me to connect the two).

Nigel, could you explain this in a little more detail please. In particular, what is the anti-ransomeware feature? Excuse my ignorance, but I didn't know such a feature existed.

Mike,

go to windows control panel, virus and threat protection.... and near the bottom is Ransomware Protection.

With that switched on PUTFILE() was giving this message when i selected a filename that didn't already exist.

If i selected a filename that did exist it then didn't get overwritten by, for instance, STRTOFILE() - but there was no error message.

I only saw it do that in a compiled .exe. Worked fine from the VFP IDE command window which still confuses me.

In control panel you are able to select folders to protect and apps that can bypass this protection; first attempt at 'whitelisting' my .exe didn't work though.

I only tripped over this in the middle of doing something else and will have to find time to re-visit. But thought it worth posting asap.

p.s.
the common dialog .showsave() behaved as if both OFN_OVERWRITEPROMPT (0x00000002) and OFN_PATHMUSTEXIST (0x00000800) are set even though .flags = 0.

Thanks for the clarification, Nigel. It took me a while to find the ransomware protection (possibly because of some non-standard security settings). I'll investigate further.
