Need guidance, Thanks Abhishek. Learning is a never ending process of Life. Re: Procedure Entry Point could not be located Tomasz Sowinski13-Sep-02 2:49 Tomasz Sowinski 13-Sep-02 2:49  Module32Next isn't available on NT4. AFAIK, there's no redistributable providing ToolHelp32 functions you could install on NT4. You'll have to use PSAPI instead.

CAsyncSocket is not too good documented for use in multithreading enviroment. I wrote some testing programs, so i found out that all callback functions are called in the same thread, throught message map (correct me if i'm wrong). Here's what i need : Implement communication functions with CAsyncSocket in separate working - non GUI thread. 1. Should I create message map for this thread ? (an how ?) 2. i need sometimes to wait for incoming data. How to implement waiting ? Is it possible to make GetMessage() loop to wait ?? how ? I don;t understand how and where does CAsyncSocket dispatch socket notification messages and translates them to callback. How does this work ? MFC source is too big for studying. Thank you rrrado Re: Please help with CAsyncSocket Rickard Andersson2013-Sep-02 2:59 Rickard Andersson20 13-Sep-02 2:59  I wouldn't use any of the socket classes that MFC has if I were you! I would code it from scratch! But... if you do want to use it, it's up to you! Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!

Re: Please help with CAsyncSocket Anonymous13-Sep-02 17:11 Anonymous 13-Sep-02 17:11  Well, an asynchronous socket concept is thought to run in one thread context by purpose! It has some advantages (for some kind of tasks). If you are sure that a multithreading concept fits better to your task, use a different socket class! For example our loved codeproject provides some kind of (IO completition port?) network classes... check it out: http://www.codeproject.com/internet/ btw Anderson... CAsyncSocket is not perfect implemented (missing asynchronous DNS, no reference buffering), but it's not *that* bad...

My problem is this... I have created a view that has tabs like a property sheet. My View class is derived from TabbedView a class derived from CCtrlView. TabbedView class uses dialog resources to define the contents of a page. Inside a page I create a CRichEditCtrl using the Create member function. The applications scrollbars are created manually in the CMainFrame::OnCreate() member function (without using the ES_CENTER or ES_RIGHT styles) and are positioned using the RecalcLayout() member function. In the CMyView::OnVScroll() handler the contents of the RichEditCtrl are scrolled vertically using the LineScroll member function. The problem is that when trying to use the LineScroll member function to scroll the contents of the RichEditCtrl horizontally in the CMyView::OnHScroll() handler nothing happens. If anybody has a suggestion on what might me wrong he/she is most welcome! Thanks... Re: Scrolling problem! Tomasz Sowinski13-Sep-02 0:42 Tomasz Sowinski 13-Sep-02 0:42  You need to handle scrolling events in the rich edit's parent - probably it's the page window. The parent gets EN_HSCROLL/EN_VSCROLL notifications. Just don't forget about ENM_SCROLL in SetEventMask call.

However, I want to scroll the contents of the RichEditCtrl through the scrollbars in the FrameWindow and not the scrollbars in the RichEditCtrl (when for example it is created with the WM_HSCROLL style). I tried handling the EN_HSCROLL notification but they are issued when a user tries to scroll using the scrollbar in the RIchEditCtrl and not the Frame window. Is this what you had in mind???? (I like the six pack moto but right now I could use a bottle of whiskey...)
