Hello all I'm new to doc/view architechture. I want to create a simple text editor which have to enable me to enter text, open files, edit,cut and copy. I'm using MFC AppWizard and accepting the defaults. It's creating a basic skeleton and when I ran it it show's up a simple editor, but when I open a file it's not showing the contents. Similarly its not allowing me to enter anything. When creating the application if I change the base class of myview to CEditView then I'm able to do all the above operations. But I want to implement all the functionality just by deriving from CView. Can anyone help me in this regard? Any example code or article which explains how to do will be of great help. Thank you very much for your help. Hari.

Hello all How do one can detect whether a particular port is a serial port or virtual com port created for bluetooth? In the case of win2000 and winXP under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM ports are listed as /device/serial0 // serial port /device/Btport1 // bluetooth virtual com port So in the case of win2000 and winXP, I've no problem in distinguishing a serial port from virtual bluetooth port. But in the case of win98 and winMe all the ports are listed as COM1 COM2 .. and so on. so how do I make an application to recognize bluetooth ports on all the windows platforms? If anyone know how to do it please help me. many thanks for your help. Hari.

Hello all I'm programming windows systray and want to put an icon in the sytray which can popup balloon tooltips. I'm using win2000 with visual studio6. The problem is the header file "shellapi.h" which I've seems like it doesn't support balloon tooltips. Here's the NOTIFYICONDATA structure I find in the hearder file typedef struct _NOTIFYICONDATAA { DWORD cbSize; HWND hWnd; UINT uID; UINT uFlags; UINT uCallbackMessage; HICON hIcon; CHAR szTip[64]; } NOTIFYICONDATAA, *PNOTIFYICONDATAA; This structure doesn't have the members like "szInfo" which has to be used to popup balloon tooltip. I refer to microsoft docs where it says version>5 is needed, when I check my shell32.dll version it shows as >5. Do I need to have new header file? If yes, where can I download from? Can any one help me? Many thanks for your help Hari.

Hello all I'm getting this error in my code and my stack trace is the following . _NMSG_WRITE(10) line 221 abort() line 44 + 7 bytes AILERONPUSH! terminate(void) + 111 bytes AILERONPUSH! _CxxUnhandledExceptionFilter(struct _EXCEPTION_POINTERS *) + 46 bytes KERNEL32! 77eab45f() KERNEL32! 77e8b2eb() it's saying that "user breakpoint reached at xxxxx". I'm having an application in which I've one parent thread and 5 child threads. parent thread read records from database and assign them one by one to child threads for processing. I'm maintaining a queue which contains handles to child threads. Queue will be empty when all the threads are assigned a record and at this point parent thread will wait. once each thread finishes it's job it will put it's handle in queue so that parent can assign him the next record. I'm experiencing the above error only if the no. of records to be processed are more than no. of threads( In this case threads will be used repetitively by parent thread depending upon their availablility in queue). Can any one help me resolve this error? It'll be of great help if anyone can give me insight into situation's that cause the above error. Thanks for your help Hari.
