Personally, I am very happy to see developers from all over the world being paid properly for their skill and efforts. I am all in favor of bounties. I do not think people should be paid by personal relationships that they can establish locally, but for its technical competence above . However, personal relationships may prevail and the choice rests with a local programmer. In this case, no much can be said, except the recommendation to form a team with local staff to win your prize.

Hi guys

got a issue where i need to be able to hook into the windows message que so i can trap messages like WM_GRAPHCHANGED etc as i have ported a media player writen around directshow in delphi over to lazarus 64 bit , i would normally use something like Allocatehwnd(procname) to do this bit i can see that for AllocateHWND & DeallocHWND have stubs and are not supported.

I have tried the CreateWindowEX and it doesnt work i get an exception when i try to use it ( this has a callback function to pass messages to your procedure...)

any one got a simple idea how to get this working

I have noticed that on interfaces for win32 the widget seems to have it there but i cant call it from my unit.

for all those who didnt reply i found the simple answer was to do this put the following in front of my calls to AllocateHWND and DeAllocateHWND TWin32WidgetSet(WidgetSet).

Now it works !!!
