I built a program using MFC AppWizard(EXE), when i try to use the Global Object theApp in the Document Class it gives me an error Undeclared identifier. how can i solve this. NOTE: when i include the .CPP file that containing the decleraion it works but this is wrong i should not include a CPP file Thank you all, Best Regards Mohammad Zakarni Re: theApp error Pavel Klocek19-Oct-02 22:32 Pavel Klocek 19-Oct-02 22:32  theApp is defined locally in cpp file of your CWinApp derived class. Use AfxGetApp() instead. Pavel Sonork 100.15206 Re: theApp error mzakarni19-Oct-02 23:12 mzakarni 19-Oct-02 23:12  Thank you...

How to write code to do that? Thank you. Re: How to write data in exist text file? tongc19-Oct-02 14:50 tongc 19-Oct-02 14:50  You can use CreateFileMapping() method or the ReadFile functionalities from Win32 API. Read more in MSDN!!! Re: How to write data in exist text file? Nish Nishant19-Oct-02 17:08 Nish Nishant 19-Oct-02 17:08  You can use the CFile class. Open the file in read mode[CFile::modeRead], seek to the end [CFile::SeekToEnd], and write your new stuff[CFile::Write].

Abin19-Oct-02 13:54 Abin 19-Oct-02 13:54  Is there a function in standard C++ library that converts a valid hexadecimal string into an integer? For example: char sz[] = "0xffff"; // or without the "0x" sign<br /> DWORD dwDec = SomeFunc(sz); // now value of dwDec is 65535 Of course this can easily be done by writing a function by myself but I'm just asking...

How shall I call Stepit to reflect this progress? Some of the functions belong to other classes, not my View class. Re: progressctrl question Max Santos19-Oct-02 16:22 Max Santos 19-Oct-02 16:22  if you have time consuming functions , its good to put them in a new thread maybe you need to send a WM_PAINT or call the RedrawWindow of the progress control in order to reflect the changes made by the StepIt(), because if you have a very time consuming function in the main thread, the CPU will not process the windows messages until that function returns (i think) _______________________________ Portal Imoguia       Software Imoguia MSN:maxsnts@hotmail.com Re: progressctrl question Michael Dunn19-Oct-02 18:11 Michael Dunn 19-Oct-02 18:11  Actually, WM_PAINT is a message you never send yourself. RedrawWindow() is the correct way to make a window repaint. --Mike-- "I'd rather you just give me a fish today, because even if you teach me how to fish, I won't do it.

My app uses both. Can I distribute my app without these two and assume the user will have it automaticall? Thanks Re: can we assume this? Le centriste19-Oct-02 16:14 Le centriste 19-Oct-02 16:14  I don't think you need the .tlb file. These files are needed at compile-time, isn't? If I'm wrong, please enlighten me Michel It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to. - TreeBeard Re: can we assume this? ns21-Oct-02 3:00 ns 21-Oct-02 3:00  I was using the Visual Basic packager and it included the tlb, so I really dont know... Appreciate your help, ns Re: can we assume this? Max Santos19-Oct-02 16:29 Max Santos 19-Oct-02 16:29  no, its not a good idea to assume that the client have msadox.dll _______________________________ Portal Imoguia       Software Imoguia MSN:maxsnts@hotmail.com
