I have a little problem, and that is sending richedit streams to another external richedit control, It seems that by sending streams it adds unseen unidentifyed charactors along with formatted code from the original richedit to the external richedit control, this results in problems in the external richedit control, because this richedit control is actually a Richedit20A box that send formatted chat text to a chat client, the client wont accept it because of unknowen charactors, I have tryed using trim function before sending the string into a stream and it makes no diffrence, So my question is ... Is there another way to send formatted text from a TRichEdit control to an…

Its nice to see since I posted some source codes people find it useful, I have held of with posting source codes because I did'nt feel My skills was upto the standards of this forum, I have learnt a lot from this forum in the past 2 years So I want to give back what I have learnt as a thank you to the Snd community.

Masm + Vc + Qword == &$#!"
by Killboy- 1 reply
- 4.8k views
Heya I just tried coding something in C++ which exports a function in a dll that takes an ULONGLONG param. Now I was trying to create a MASM inc file for the prototypes. The problem is that if I use Function PROTO STDCALL Value : QWORD it seems to swap the lo and hi values. This seems to be a problem with C++ where the low part of the qword is located at [offset] and the high part at [offset+4]. (Offset being the address of the qword) AFAIK it's the other way around in MASM so I was looking for a data type that would behave the same... Instead of having to use: Function PROTO STDCALL ValueLow : DWORD, ValueHigh : DWORD Or am I wrong and MASM does it the same wa…
