EXE on DOS and win32 pranavamhari4-Jan-04 19:54 pranavamhari 4-Jan-04 19:54  hi, can one write an exe that will run on DOS and windows ? I mean in windows it should be able to show message box, dialogs etc. I am asking this because one program I downloaded from net seems to do this. regards hari Hari Krishnan Re: EXE on DOS and win32 abc8764-Jan-04 20:06 abc876 4-Jan-04 20:06  you can display Message Box and call MFC in Win32 Console Applicationscreated in VC++ Muhammad Shoaib Khan http://geocities.com/lansolution Re: EXE on DOS and win32 Rickard Andersson205-Jan-04 2:55 Rickard Andersson20 5-Jan-04 2:55  That is a Win32 Console Application which you can do GUI in. With DOS applications you can't deal with GUI. Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318 gethostbyname failed in Window XP lauch24-Jan-04 19:34 lauch2 4-Jan-04 19:34  I found that gethostbyname() would be failed if I disconnected the cable from the LAN adapter. However, if I re-connected the cable to the LAN adapter, it worked fine. More info is: If the cable is disconnected from the LAN adapter, ipconfig command will return the following: Ethernet adapter Local Area Connection: Media State . . . . . . . . . . . : Media disconnected Any idea? Thanks in advance, lauch. Re: gethostbyname failed in Window XP Roger Wright4-Jan-04 20:42 Roger Wright 4-Jan-04 20:42  getHostByName() retrieves information from the DNS or WINS server. If you unplug the cable it has nowhere to look for the information.

Re: gethostbyname failed in Window XP lauch24-Jan-04 21:31 lauch2 4-Jan-04 21:31  Thanks, Roger Wright. Then, if I unplug the cable, how can I retrieve the IP address of the local machine? I have used the following ways, but all they are failed: 1. Use API getaddrinfo() 2. Use API GetAdaptersAddresses() 3. Use INTRFC.exe sample, which in turn use the API WSAIoctl(s, SIO_GET_INTERFACE_LIST, NULL, 0, &localAddr, sizeof(localAddr), &bytesReturned, NULL, NULL); In addition, I know the IP addresses are stored in the regitry. However, I want to use other ways to IP addresses if the cable is unpluged. thx, lauch. CPropertySheet failing to create Kibble4-Jan-04 18:41 Kibble 4-Jan-04 18:41  I am having trouble getting a CPropertySheet to not fail create. I've set it up like this example: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_cpropertysheet.3a3a.create.asp The differences are its not in a CView derived class. Does that really cause the Create to fail? It will be a huge pita to derive the outer class from CView. I'm getting Assertion failed in dlgprop.cpp line 201, no other information.

Are there any other (perhaps lower-level) functions that can be used to read data from files? Specifically, I would like to know which function DirectShow uses when playing a WMV file (more percisely - which function the filter DS loads calls). I know that it is not one of the 3 mentioned above...

I want to know what Win32 API functions are there, to read from files. Re: Thanks, but I would like to know which SYSTEM-LEVEL functions jan larsen6-Jan-04 2:00 jan larsen 6-Jan-04 2:00  ReadFile is the most low level API call you cant get for reading directly from a handle, but there is also a more sophisticated way to read a file. You could create a memory mapping of the file and then use any developer tricks you can dream up. An example: If the file is a bitmap file, then you can cast the void * you get from the mapping to a struct BITMAPFILEHEADER *, and then read from the members of that structure.

Any chance that it uses some sort of direct disk access? Or maybe reads the file in a different process and streams the data through COM to my process? Any other ideas? Thanks! Re: Thanks, but I would like to know which SYSTEM-LEVEL functions jan larsen6-Jan-04 21:12 jan larsen 6-Jan-04 21:12  The whole point of DirectX is to be an abstraction layer that hides the awfull truth which is: If a DirectX driver for the given hardware exists, in your case this is the soundboard driver, then the features of that driver is used. If such a driver does not exist, then DirectX will emulate the DirectX functions, using the usual Win32 API calls. So, what you are looking for is not an API call, but a way to access the hardware directly which is not at all like reading a file (unless of course you are used to read files in assembler ). But why not use DirectX then?, if there is a difference in performance compared to the ASM solution, then it is a very small one.
