Re: Detect FIREWIRE Device ksrameshkanth12-Jul-07 21:43 ksrameshkanth 12-Jul-07 21:43  Hi, I am not sure about FIREWIRE, But generally device detect can be found by using the message ON_WM_DEVICECHANGE(). Also refer the following link http://www.codeproject.com/system/HwDetect.asp Regards, Rameshkanth BORN TO WIN need a similar function as "getchar()" bloodwinner10-Jul-07 22:01 bloodwinner 10-Jul-07 22:01  if I am using getchar(), then the execution of the program will stop here if no input is given. could someone help me figure out if there is another way? Aim: while any input is given, save it to a variable, if not, keep on executing program without stop. I have used multithread, but it did not work well when I put it running at background. I am using C Re: need a similar function as "getchar()" InOut.NET10-Jul-07 22:18 InOut.NET 10-Jul-07 22:18  I don't think there is a function that 'does not wait for input'. Re: need a similar function as "getchar()" bloodwinner10-Jul-07 22:31 bloodwinner 10-Jul-07 22:31  not necessarily a single function, but with the usage: keep program running, while accept the input if any Re: need a similar function as "getchar()" CPallini10-Jul-07 22:38 CPallini 10-Jul-07 22:38  What about multithreading? If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile. Re: need a similar function as "getchar()" bloodwinner10-Jul-07 22:48 bloodwinner 10-Jul-07 22:48  I had been used multithread, and it works strange. It works fine when I run the program at foreground, the first thread keeps running while the second thread waiting for input. But it does not work well when I run it at background. Without any inputs, both the first and second threads will stop. Only after I manually switching it back to run at foreground, then the first thread runs again. So I really want to find something similar and simpler than the mulithread way.

Re: need a similar function as "getchar()" Russell'10-Jul-07 22:45 Russell' 10-Jul-07 22:45  I think you can use feof (I think it works also on stdin) to know if the keyboard buffer is empty, elseway get the char with getchar. In this way you don't lock the program to wait a new key.

I assume you can establish a pipe interface with STDIN and then use select to monitor your fd. you can put select in a while loop to monitor the fds continuously and maybe fork() this function if you want control back... Conversion of base64 encoded data into CBitmap Vikhyat Karumanchi10-Jul-07 21:53 Vikhyat Karumanchi 10-Jul-07 21:53  Hello all, I want to convert base64 encoded data into a CBitmap. Here's my code fragment. The image is coming like an x-ray. It is not a monochrome bitmap. BYTE _ICONDATA[2500]; CString pICON = _TEMP->_ICON; int len = 1080; BOOL p = Base64Decode (_bstr_t(pICON), lstrlen (_TEMP->_ICON), _ICONDATA, &len); pIcon.CreateBitmap (16, 16, 1, 32, NULL); DWORD x = pIcon.SetBitmapBits (len, _ICONDATA); Please help!!
