how to change the default PC soundcard settings when i have two soundcards in PC max_xiayi31-Aug-04 23:16 max_xiayi 31-Aug-04 23:16  I know how to change it by manually changing the control pad settings. But what i want to know is change the settings in my programm.How? please contact: max_xiayi@hotmail.com extract specific data from file M_A31-Aug-04 23:10 M_A 31-Aug-04 23:10  Hi I have a problem where I want to retrieve data from an ASCII file(containing grid points) an sort it into another file(in this case VTK file format). The thing is that my source file contains alot of text and I want to be able to jump to a certain place for instance "Number of points = ". I have not found a suitable way to adress this problem. I know how to go to a certain position using the usuall operators fstream and so on where I only can go to a specif position. I have looked around but found nothing. Would be grateful for any help! /M Re: extract specific data from file Maruf Maniruzzaman1-Sep-04 0:02 Maruf Maniruzzaman 1-Sep-04 0:02  Why you've not given the input file format? If you provide think it will be easier to answer your question. Tomorrow is a blank page Let me know if I am wrong with the information above Re: extract specific data from file M_A1-Sep-04 0:23 M_A 1-Sep-04 0:23  Thanks for pointing that out Manir. The file is from a preprocessor called NASTRAN(Fintite Element calculations on mesh). It's a file in ASCII format called f06. Re: extract specific data from file Maruf Maniruzzaman1-Sep-04 1:57 Maruf Maniruzzaman 1-Sep-04 1:57  I am not sure if I really have understood your problem. But if you are trying to go to a location containing a predefined string you can use Knuth-Moris-Patt method to find it from a stream. Tomorrow is a blank page Please let me know if I am wrong with above information Detecting COM ports Cedric Moonen31-Aug-04 22:27 Cedric Moonen 31-Aug-04 22:27  Hello ! I need to know all the available COM ports on my computer. How can I do that ? Is it a function for doing that ? Thanks Re: Detecting COM ports ThatsAlok31-Aug-04 22:44 ThatsAlok 31-Aug-04 22:44  here is small code snippet,i found it from CSerrailPort clas at CP // prepare port strings sprintf(szPort, "COM%d", portnr); sprintf(szBaud, "baud=%d parity=%c data=%d stop=%d", 19200, 'N', 8,1); // get a handle to the port m_hComm = CreateFile(szPort, // communication port string (COMX) GENERIC_READ | GENERIC_WRITE, // read/write types 0, // comm devices must be opened with exclusive access NULL, // no security attributes OPEN_EXISTING, // comm devices must use OPEN_EXISTING FILE_FLAG_OVERLAPPED, // Async I/O 0); // template must be 0 for comm devices if (m_hComm == INVALID_HANDLE_VALUE) { // port not found delete [] szPort; delete [] szBaud; return FALSE; } ----------------------------- "I Think It will Work" Formerly Known As "Alok The Programmer" at CP ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: Detecting COM ports Cedric Moonen31-Aug-04 22:47 Cedric Moonen 31-Aug-04 22:47  Hi ! Thanks for your response but this is not what I'm looking for. I don't want to open every port to test if it exists. I'm lloking for a function (or maybe something in the registry ?) that gives me all the ports available on my machine. Re: Detecting COM ports Nicholas Cardi1-Sep-04 3:45 Nicholas Cardi 1-Sep-04 3:45  You can detect all installed com ports by looking in the registry under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM" Forever Developing Re: Detecting COM ports Antony M Kancidrowski1-Sep-04 3:25 Antony M Kancidrowski 1-Sep-04 3:25  Not sure if this will help but if you look in the registry HKLM\SYSTEM\CurrentControlSet\Services\Serial\Enum Gives a list of serial devices and a count!?

Muse on it further, I shall return! - David Williams (Little Britain) Re: Detecting COM ports Cedric Moonen1-Sep-04 3:40 Cedric Moonen 1-Sep-04 3:40  I think I've found another key that may help me: HKEY_LOCAL_MACHINE\Hardware\deviceMap\SerialCOMM and there is a list of (I think) all the serial port of my machine (virtual or not). Do you think this is a valid key (present on all computers) ? Know, I want to retrieve the names (COM1, COM3, ...) but I don't know how to do this ? I can retrieve the number of 'values' but how can I retrive their values (I don't know the names of these keys...) Any idea ? Thanks Re: Detecting COM ports Nicholas Cardi1-Sep-04 3:53 Nicholas Cardi 1-Sep-04 3:53  You can enumerate the registry by using RegEnumValue Check you local MSDN help files for more info Forever Developing Re: Detecting COM ports Cedric Moonen1-Sep-04 4:05 Cedric Moonen 1-Sep-04 4:05  Ok thanks, I will take a look. This is the first time I use the registry so if you can point me to an article or something that describes how to use it correctly that would be nice (In the MSDN, there is no doc about that, just the different functions and what they do ) Re: Detecting COM ports Nicholas Cardi1-Sep-04 5:34 Nicholas Cardi 1-Sep-04 5:34  Here is a code project artical on the subject http://www.codeproject.com/useritems/serial_portsenum_fifo.asp Forever Developing Re: Detecting COM ports Antony M Kancidrowski1-Sep-04 4:53 Antony M Kancidrowski 1-Sep-04 4:53  Yup, they are available on Win2003, XP and W2K at least. It appears that the names of the keys will be \Device\Serial<n> where <n> is a number from 0 upwards! If you read the number of devices from the Enum of the serial section (as i described above) then you could loop round reading the device map names as you have found (altering <n> for each iteration of the loop).

Re: Global &amp; Static global wb31-Aug-04 20:54 wb 31-Aug-04 20:54  hm.. as I remember, if you use static on a global variable, it is only visible in this single cpp file for the linker. Re: Global &amp; Static global Lim Bio Liong31-Aug-04 20:50 Lim Bio Liong 31-Aug-04 20:50  Hello Vikrams, A global variable and a static global variable are both global variables. That is, they are not defined in the context of any C++ class. Examples : int g_int = 0; static int g_static_int = 0; The difference between a global variable and a static global variable is that the global variable can be accessed in any CPP file while the static global variable can only be accessed within the CPP file in which it is defined. Example : source1.cpp : int g_int = 0; static int g_static_int = 0; void func1() { ... g_int = 20; // OK ! ... } void func2() { ... g_static_int = 35; // OK ! ... } source2.cpp : extern int g_int; extern int g_static_int; void func3() { ... g_int = 81; // OK ! ... } void func4() { ... g_static_int = 19; // Not OK ! You will get a linking error. ... } -Bio. Re: Global &amp; Static global vikramlinux31-Aug-04 23:20 vikramlinux 31-Aug-04 23:20  Well.. I got it. Thanx a lot.

Re: what are the video Streaming rates/ frequencies of Direct Show Jon Hulatt31-Aug-04 23:03 Jon Hulatt 31-Aug-04 23:03  Query the output pin on the source filter you're using, to find out what media type it is using. It's all in the DirectShow documentation. Jon #include <beer.h> How to move internet explorer toolbar, address bar and links bar Dan Neilsen31-Aug-04 19:56 Dan Neilsen 31-Aug-04 19:56  Hi All, What I am trying to do is, when a button is pressed in my application, it opens a browser that looks very similiar to the Windows XP F11 Theatre view except that it has the menu and the status bar would be down the bottom. To this end I thought I would a IWebBrowser2 object, find the applicable toolbars in the rebar control and move them to where I want them to go. Here is what I have so far: HRESULT hr = CoCreateInstance(CLSID_InternetExplorer, NULL, CLSCTX_LOCAL_SERVER, IID_IWebBrowser2, (void**)&m_pWebBrowser2); hr = m_pWebBrowser2->QueryInterface(IID_IWebBrowserApp,(void**)&m_pIEApp); long hIE; // get a window handle so we can resize and show the browser window. hr = m_pWebBrowser2->get_HWND(&hIE); hr = m_pWebBrowser2->put_AddressBar(true); hr = m_pWebBrowser2->put_StatusBar(true); hr = m_pWebBrowser2->put_MenuBar(true); hr = m_pWebBrowser2->put_ToolBar(true); // use CWnd to make showing the window etc easy m_wndWebBrowser.Attach((HWND)hIE); m_wndWebBrowser.ShowWindow(SW_SHOWMAXIMIZED); //REBAR CONTROL //Find Rebar Control CWnd* workerWnd; CWnd* rebarWnd; bool foundPersonalBar = false; long childcount = 0; UINT searchState = GW_CHILD; while(!foundPersonalBar) { workerWnd = m_wndWebBrowser.GetWindow(searchState); searchState = GW_HWNDNEXT; childcount = workerWnd->GetWindowedChildCount(); if(childcount != 1) continue; rebarWnd = workerWnd->GetTopWindow(); if(!rebarWnd) continue; childcount = rebarWnd->GetWindowedChildCount(); if(childcount <= 3) continue; foundPersonalBar = true; } At this point rebarWnd is the rebar that I need (ie. the parent to the toolbar, menubar, etc) but I am not sure where to go from here. The problems I am finding are: - I cannot determine which of the child toolbars is the address bar, which is the menu bar, etc, etc - How to move them This will probably be a very easy thing to do but I am fairly inexperienced in this kind of programming. Any help would be appreciated. How do I detect resource leakage? YunYan31-Aug-04 18:23 YunYan 31-Aug-04 18:23  I have a program with multiple doc/view in order to read STL files. If I just open the file and then close the file again and again, I can’t open any window finally, even opening a pop-up menu in another process is unavailable. I think that there must be a resource leakage, but I don’t know how to detect a resource leakage. Thanks for your help! Re: How do I detect resource leakage? Tim Smith31-Aug-04 19:26 Tim Smith 31-Aug-04 19:26  If you are using the CRT, you can enable CRT leak detection and then dump a report on exit. It will then list all your leaks. A better solution is to use some type of leak detection software, but the generally cost money. Tim Smith I'm going to patent thought. I have yet to see any prior art.
