    - Where can I get rs232 Documentation? Hello, I am experimenting with rs232 and I would like to know where I can get documentaion explaining the libraries in the serial classes. If I do: CSerialWnd MySerial; and after the dot of my object we get a collection of methods and members that we can use... ex: MySerial.Break .CancelComIO .CheckPort .CheckRequirements . and so on..... It would be nice if there can be some literature that explains the function of every one of these.... I guess some can be straight forwards, but there is some I don't know what they can be used for! If such document does exist, guidence to abtaining it would be very greatfull! All sugestions appreciated! Thanks -- Best regards Robert Tag: How to modify the time and/or date of a file? Tag: 265826

    - Winsock bind API Server socket uses bind API to bind IP and port. Is it possible to do the same for client socket ? My intention is to have the client socket to use specific port number when connecting/sending data to TCP server. Reason is client's side firewall only allow specific port number to be used when connecting to outside world. Thanks. Tag: How to modify the time and/or date of a file? Tag: 265814

    - Problem using the GetFileTime() Environment: W2K+SP4 & VS2005. As part of a console application, the following compiles successfully but result a run time error message. string input_fname; FILETIME ftC,ftA,ftW; BOOL success; WIN32_FIND_DATA FindFileData; HANDLE hFind; hFind = FindFirstFile(input_fname.c_str(), &FindFileData); if (hFind == INVALID_HANDLE_VALUE) Error_msg(" FindFirstFile() failed"); if (!GetFileTime(hFind, &ftC, &ftA, &ftW)) Error_msg(" GetFileTime() failed"); Output looks like that: Error code 6: The handle is invalid. Calling function or case: GetFileTime() failed My question is, how come, that since the first "if" passes w/o an error, how could it possibly be that the send "if" fails claiming that the handle hFile is claimed to be invalid?!

    - BYTE to LPCTSTR ? Hi, I have the following line of code which reads bytes from an rs232 port: Please consider the following code: ============================================ DWORD dwBytesRead = 0; BYTE abBuffer[100]; TCHAR szBuffer[100]; MySerial.Read(abBuffer,sizeof(abBuffer),&dwBytesRead); ============================================ Now, I need to print abBuffer to the screen, god knows I tried ! TextOut(hdc,100,100,abBuffer,100); //no good! TextOut(hdc,100,100,TEXT(abBuffer),100); // no good! TextOut(hdc,100,100,(char)abBuffer,100); //I didn't expect this one to work! TextOut(hdc,100,100,wsprintf(szBuffer,TEXT("%s")),abBuffer); //Forget it! :( By now I have looked for answers in Petzold, Osborn and SAM's books and I now need help! >>>> a g a i n! Anyone! BYTE is typedefed in Windows as so, typedef unsigned char BYTE; -so this tells me that a byte is really defined as a char... right ? -A char is 8 bits ... right ? So if the 4th parameter of TextOut takes a LPCTSTR, then how would I convert this so that TextOut would accept it ? Ooooohhhhfffff ! Anyone.....Please! -- Best regards Roberto Tag: How to modify the time and/or date of a file? Tag: 265807

    - Is it because of SubClassing? Hello, I don't mean to double post, however I was just wondering if it is because I am not subclassing my child window that the following program doesn't work? Here is the problem: I realized that the WM_KEYDOWN handler did not pick up my keystrokes on my child window. I have a WM_KEYDOWN handler in my main window, and when I press say F1 key, I can trap it with a break point, but when I am in my second window, which is a 2nd WindProc, I cannot trap the WM_KEYDOWN messages. here is the basic code: ===================================WndProc.CPP LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { ...other code... switch(message) { case WM_KEYDOWN: switch(wParam) //**********Break point recognized at debug time { case VK_F2: ShowWindow(hdCW1,SW_HIDE); break; } return 0; case WM_COMMAND: if (LOWORD(wParam) == WindowButtons[1].MW_btC_ID) //If Button #1 { hdCW1 = CreateWindow( //Create Child window #1 szCW1_ClassName,szCW1_Name, WS_CHILD | WS_CAPTION | WS_SYSMENU, 150,50,400,300,hwnd,(HMENU)CW1_ID, (HINSTANCE) GetWindowLong(hwnd,GWL_HINSTANCE),NULL); ShowWindow(hdCW1,SW_SHOW); //Show child window #1 } return 0; ...other code.... =============================================== And here is the code pertaining to the child window, pressing F1 key does not get trapped by break point in this winproc? ===================================WndProc_CW1.CPP LRESULT CALLBACK WndProc_CW1 (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { ...other code... case WM_KEYDOWN: switch (wParam) //Break point here! Break point NOT recognized at debug time { case 0: //Dummy case break; } return 0; ...other code.... ================================================= Its like as if when I am in the child window and I press say F1 key, the WM_KEYDOWN message is not sent, and even if I have a break point on the following line: switch (wParam) debug doesn't stop on that line, it goes right through as if I had no break point ???? So, again... can this be because I should use WM_KEYDOWN in a subclassing proc? If anyone has any ideas, please get back! All help appreciated!

    - Help DataSets I am looking for some advice or best practices on how to do this.. I have an XML file, that I read into a dataset via ReadXML: PlayersDataSet.Clear(); PlayersDataSet.ReadXml(filePath); What I would like to do is query the dataset so I can search for people from California, or people older than 65 or something? Is there any way to make a SQL data adapter that uses a dataset as the source data? How can I parse the content of the dataset? I have also tried a DataGridView but haven't found the mechanism to do this since ReadXML is being used to generate the schema information currently.

    - how to read x86/x64 flags Hi all, After performing some operations I need to read flags such as the carry, the zero, the negative. For instance: static bool carry; int sub(int x, int y) { int res = x + y; carry = get_cpu_carry_flag(); return res; } Is there and way to implement this get_cpu_carry_flag() function for vc2005? I certainly need a fast way to do it. The inline assembler would do it, but it is not there anymore. Artem Tag: How to modify the time and/or date of a file? Tag: 265800

    - temporary objects in VC++ 6.0 vs VC++ 7.1 Hi, My organization recently migrated from VC++ 6.0 to VC++ 7.1. We have found that the temporary objects created in VC++ 6.0 were not destroyed after the end of the expression or statement, thus temporary objects are available with in the scope where they were created. However in VC++7.1, temporary objects are being destroyed after the statement in which they was created. Thou C++ standard says that the temporary objects are destroyed at the end of the statement, I am not sure why VC++ 6.0 and 7.1 exhibit different behaviours, I would like to know if VC++7.1 includes this new feature or it is an undefined behaviour? Also where can I find the features/differences for 6.0 and 7.1? thanks a lot jk Tag: How to modify the time and/or date of a file? Tag: 265799

    - How to supress the compile error on STL code? Hi, I am using VC7 compiler, my code uses STL a lot. I find that, if there are some code error, the compiler prints out a lot of error messages, most of them are about STL, for example, c:\STL\export\stdexcept(74) : see reference to class template instantiation '_STL::basic_s ring<_CharT,_Traits,_Alloc>' being compiled with [ _CharT=char, _Traits=_STL::char_traits<char>, _Alloc=_STL::allocator<char> ] While the real problem is in my code, even though VC compiler correctly indentifies the error line, with so many STL messages, it is hard to look for the real error message. I wonder if there are some way to supress them? Tag: How to modify the time and/or date of a file? Tag: 265794

    - rs232-[B] Success! rs232 communications between VC++ and a PIC microcontroller have been established! What a relief! I *must* be very thankfull to the news groups for this ! You guys were great, and I would of never of made it without your help! Although all was constructive, I ran into one last but simple question! As I have been learning VC++ and some of all of its vast world of programming, Windows data types have creeped back, and as I looked at posts on this from 6 months ago, I feel I would still need some guidence regarding this particular issue. So here is my question: As VC++ is the software that I am using on the PC end, as you may know, one of the methods of the serial class is : MySerial.Write("x"); Therefore as you know, the first parameter of the "Write" function takes a LPCSTR. You see.... at the microcontroller end, the C code reads this byte by the following line: c=getc(); in the code fragment below: ===================== void get_string(char* s) { int len; char c; len = 0; do { c=getc(); //getc is a ready made function by the compiler which waits // for a character to be received. So until VC++ doesn't // send something, the controller stays at this line! if ((c>=' ')&&(c<='~')) //if 'c' is within range, then append to array s[len++]=c; } while(c!=13); //Wait for enter key! ...other code... ====================== In the above code, I have only included the pertaining lines to my question, but its pretty much representative of what the function consists of. So, in the above code, it waits for a character and once recieved, it appends it to "s". So, if VC++ sends a "B", then a "B" will be appended in the string array "s". This continues until VC++ sends a ascii code for "enter key", which is ascii code 13. My question is, given the code shown above for the *PC end*, how would VC++ , by using code, send an "enter" or a "13" in this case? I tried, MySerial.Write("13"); //The controller only reads: "1" instead of 13 The next line doesn't work either: MySerial.Write(13); And before I try all kinds of type castings, I would prefer to get some understanding of what needs to be done. I mean, if MySetrial.Write() takes a LPCSTR and the C language at the controller end needs to see a 13 to understand that VC++ sent the 'enter key' code, then I need to convert 13 to "13"... right? What's happens now, is that the controller doesn't recognize 13, no matter which of the following commands I do: MySerial.Write(13); or MySerial.Write("13"); or int x; x=13; MySerial.Write((WCHAR)x); //Which makes no sence, since it expects a LPCSTR If I may be excused on this one, its been a while since I have been set straight on Windows data types, even though given the fact that the news groups have done more than great job at explaining me this stuff months ago! All help much appreciated! And again, thankyou all fellow newsgroups! -- Kind regards Roberto Tag: How to modify the time and/or date of a file? Tag: 265790

    - #pragma ( default : 4061) not working I want to enable warning C4061 in VC6 SP5 (for some reason, my company isn't approving SP6), which alerts you if a switch statement on an enumerated type doesn't handle all of the enum's members. Even in the simplest case, it does not work for me: --------------- #pragma warning (default : 4061) enum prag{ALPHA, BETA, GAMMA}; void f(prag p) { switch(p) { case ALPHA : case GAMMA : break; } } void main() {} --------------- I have cleaned and rebuilt many times on every warning level.

    - exhaustive switch bound checking See the program fragment below. I have tried it on VC8 x64. //-------------------------------------------- extern unsigned char fetch_byte(); void dispatch() { while(true) { switch(fetch_byte()) { case 0: ...; break; case 1: ...; break; ... case 255: ...; break; } } } //--------------------------------------------- VC generates a jump table for the switch statement. The case is exhaustive with respect to the unsigned char type. However, VC generates a bound check before indexing in the jump table: movzx r11d, al cmp r11d, 255 ; 000000ffH ja SHORT $LL260@dispatch_c mov edx, DWORD PTR $LN776@dispatch_c[rdi+r11*4] add rdx, rdi jmp rdx The first three lines here can be ommitted. The question is: how do I make the compiler to omit the checks? Note, that the same problem appears with an exhausinve switch for an enum type.

    - CToolbarCtrl problem I have created a class derived from CToolbarCtrl. in this class i have added some push buttons and some dropdown buttons.In which one of them is setting button.when i click this button a property sheet is displayed in which i can select and deselect a lot of options about to display a specif button on the toolbar or not. Suppose when the user selects the checkbox of "Mails" and then apply button pressed ,i want to appear that button on the toolbar and if S/He Uncheck the "Mails" checkbox i want to disappear the toolbar Mails button. to solve this problem i have send a user defined message from the propertyPage class to the toolbar so that in this message handler i could place my code to Appear/Disappear my "mails" button. I m trying to use the function HideButton() of CToolbarCtrl class in my user defined message handler but this is not working.i want that when user press the apply button the button should be reflect the changes. another way i have tried is that the buttons which i have added into the toolbar ,itried to set their "fsState" to TBSTATE_ENABLE or TBSTATE_HIDDEN, these techniques work but when i close the IE instance and start it again.i just want to reflect the changes the user have made in the Option page of propertysheet class. plz help me where i m making a mistake. Another thing is that i have make a funtion "Create" in the CToolbarCtrl derived class in which i m adding the buttons in the toolbar.and this is used as a Dll. plz tell me . Thanks in advance.

    - VB6 compatible Dll created with VC++6 problems using afxsock functions Hi I've got a problem using send() function (defined in afxsock.h) in a VB6 compatible DLL that I've made. Let me explain the situation : I'm coding a Server-Client application. - The server runs on a XPEmbedded Windows, and is programmed with VC++6. Sockets declarations and recv() & send() function are defined in afxsock.h. - The client runs on a Windows XP Fammily edition and is programmed in VB6. I had some problems in making the both communicate beacause of the limited size of paquets that can be send with winsock SendData in VB. More over I had already written the Client program in VC++6 using afxsock, that worked very well. So I had written a VB6 compatible DLL with VC++ that I've included in my VB code. The Dll launches well as I can display some MsgBox, but the characters send to the server aren't received altough the code is hardly the same to my VC++ client program. Are there some cautions to use send() in a Dll ? Here are some pieces of my codes: ///////////////////////////////////////// ///// Client Dll ///////////////////// ///////////////////////////////////////// #define TRANSF_DTF 20 void __stdcall Transfert_DTF(LPSTR string) { WSADATA initialisation_win32; SOCKET socketID; SOCKADDR_IN Sock_addr; unsigned char buffer[PAQUETETH]; unsigned char buffer_ack[4]; HANDLE hFile; char temp[30]; int packetnbr, packetnbr_ack; int size; MessageBox(NULL,"Enter the DLL","Message",MB_OK); hFile =3D CreateFile( string, // open file GENERIC_READ, // open for reading FILE_SHARE_READ, // share for reading NULL, // no security OPEN_EXISTING, // existing file only FILE_ATTRIBUTE_NORMAL, // normal file NULL); // no attr. template if (hFile =3D=3D INVALID_HANDLE_VALUE) { MessageBox(NULL, "Error", "Message", MB_OK); } size =3D GetFileSize(hFile,NULL); sprintf(temp, "size : %d", size); MessageBox(NULL,temp,"Message",MB_OK); // ******************************************************** // Winsock Initialization erreur=3DWSAStartup(MAKEWORD(2,2),&initialisation_win32); socketID=3Dsocket(AF_INET,SOCK_STREAM,0); Sock_addr.sin_family=3DAF_INET; Sock_addr.sin_addr.s_addr=3Dinet_addr("192.168.0.2"); Sock_addr.sin_port=3Dhtons(8686); connect(socketID,(struct sockaddr*)&Sock_addr,sizeof(Sock_addr)); buffer_ack[3] =3D TRANSF_DTF; compt =3D send(socketID, (char*)buffer_ack, 4, 0); sprintf(temp, "Send : %d", compt); MessageBox(NULL,temp,"Message",MB_OK); compt =3D recv(socketID,(char*)buffer_ack,4,0); sprintf(temp, "Recv : %d", compt); MessageBox(NULL,temp,"Message",MB_OK); ///////////////////////////////////////////////////////////// ////////////////////////// ///// Server/////////// ////////////////////////// // Same initialisations, then : // transf_sock =3D accept(socketID,(struct sockaddr*)&Socket_addr.sin_addr,NULL); popup(hWnd, "accepted", 40, NOIR); // display function if(transf_sock =3D=3D INVALID_SOCKET) { sprintf(temp,"error invalid transf_sock n=B0 %d", WSAGetLastError()); popup(hWnd, temp, 10, NOIR); } recv(transf_sock,(char*)buffer_ack,4,NULL); sprintf(temp, "interception : % d\n", (UCHAR)buffer_ack[3]); popup(hWnd, temp, 70, NOIR); ///////////////////////////////////////////////////////////// Both programs are blocked as the server don't receive the first 4 bytes...=20 Someone can help me ?=20 Thanks.=20 Matthieu.

    - Message Compiler - specify customer bit per message Iâ??m very new to C++ (three weeks of learning on my own) so please bear with me. Iâ??m creating my first message file to be compiled with the mc.exe message compiler and I want to turn on the customer bit for certain error codes and not others. It looks like the only way to turn on the customer bit is by using the â??c switch on mc.exe. Unfortunately that causes ALL error codes to use the customer bit. Is there a way to do this without creating two separate message files? (One with the customer bit and one without) Hereâ??s the specific scenario in case the question wasnâ??t clear. Iâ??m creating a message file contains event messages/error codes and event categories/codes. Turning the customer bit (bit 29) on for ALL the messages means that you need 32bits to reference any of the messages. But since the ReportEvent function uses a 16bit variable for the category code, you have no way to reference the 32bit category codes.

    - Changes to the C4244 warning? We compile our code under warning level 4 and want to have the C4244 warning enabled as it sometimes catch problems in the code. However, consider the following code: unsigned char a, b; a += b; // Generates warning a = a + b; // Does not generate warning The problem is that C++ will expand the type of the + expression to int and then implicitly convert the int to unsigned char, which should generate a warning. We dunno if the compiler folks at Microsoft thought "hey thats silly to warn here" and disabled the warning for the regular assigment but forgot to disable it for the += assignment or if they made an error not reporting the implicit conversion of the type in the regular assignment with the C4244 warning. We would very much like VC would not warn for either assignment operators when types are implicitly expanded and then implicitly reduced as this is never a warning you care about. Currently, we have to use the second form to avoid the warning but if the VC teams decides to warn here also we really need to write: a = (unsigned char)(a + b); And this kinda sucks. (Although it is really C++ that sucks here) Regards Ulf Johansen Tag: How to modify the time and/or date of a file? Tag: 265746

    - Help!! %n is diabled in sprintf in VS 2005 Hi, We have some code that uses %n as a conversion specifier in sprintf. That used to work fine in VC 6.0 and also in UNIX. But now, in VS 2005 that sprintf statement crashes. During the debugging I found that %n support is disabled in the source file output.c. I do need to use the dll version of the C run time library. Is there any way I can continue to link to the C run time library without any source code change? Do I have to change all my existing code to use sprintf_s which requires an additional argument? If that is the case it is a pain. What happens to the portability? Unix does not have sprintf_s. Thanks, Vnm Tag: How to modify the time and/or date of a file? Tag: 265730

After installing the service pack the file _ios.cpp was still the same that was in previous service packs (date on the file, 2000-06-13). If you refer to the individual knowledge base article it shows a file with the date of 2003-02-05. I was wondering does anyone have the hot fix that is referred to in the knowledge base article.

    - LNK 4210 comes when i migrate from VC6.0 to VC8.0 Hi, I had a DLL build using VC 6.0. I migrated the Source to VC8.0. Now I am getting the linker error "LNK4210: .CRT section exists; there may be unhandled static initializers or terminators". Please note that I have my own DLL Entry point specified in the make file for the DLL. I have checked documentation. I have tried to call _CRT_INIT function in my entry point funtion but then i get the LNK2001 unresolved external symbol CRT_INIT. Can anybody tell me the exact problem and fix for it. As far as I can figure out the constructors for global members is called by run time library. but in this case i am not able to initialize the run time library (_CRT_INIT ??)

    - IE toolbar ,How i can reflect the Settings Hi My IE toolbar is based on the Microsoft sample KKBar. I have draw a lot of buttons on it in which some are simply pushDown buttons and some are dropdowns.Beside this I have Made a Setting button.By which user can Customize the Buttons on toolbar,means S/He can select the buttons and deselect the buttons from a Property page. This information i have placed in Windows registry.When I create the toolbar i Create the toolbar based on the registry data that which button i have to appear and to which Button i have to HIde . I have completely Done it.they appear and disappear properly. But the trouble starts when i Create the toolbar i can decide From the registry data that which button i have to make appear and which button i have to make disappear. If the user Selects the setting and change the options (suppose he want to display one more button from the setting),How i can refresh my toolbar to show that button on the same instance of IE. Plz if some one knows tell me .i will be thankful to him.Buttons are displayed when i start another instance of IE,this is just bcoz the Data in the registry has been changed by the previous instance,But i want also to be on the instance that is changing the options.

    - InterlockedCompareExchange64 under VC++ 6.0: in-line assembly using cmpxchg8b ?? I am trying to implement an atomic compare-and-exchange of a "double" type, under VC++ 6.0 for WinXP. The Windows API function of InterlockedCompareExchange64 is not available for WinXP (it's only available for Vista, see http://msdn.microsoft.com/library/en-us/dllproc/base/interlockedcompareexchange64.asp ) . There is a compiler intrinsic function of _InterlockedCompareExchange64 (see http://msdn2.microsoft.com/en-us/library/ttk2z1ws(VS.80).aspx ), but this intrinsic seems to be available only for more recent versions of VC++ (such as VC++ 2005), and it's not available as an intrinsic for VC++ 6.0. So, I think that I need an in-line assembly function which, like the 2005 compiler intrinsic, uses the cmpxchg8b instruction. In-line assembly, however, is beyond my capability. I found user-mode code that uses in-line assembly and the cmpxchg8b instruction at this thread in microsoft.public.win32.programmer.kernel (see the next-to-last post): http://groups.google.com/group/microsoft.public.win32.programmer.kernel/browse_thread/thread/ecc0a35d9fcef3b5/0e3b6a23d301a62a . The code doesn't work for me. Here's what I mean by "doesn't work": I implemented the function in a singly-threaded environment, simply to test whether the function properly stores the correct double value at the destination location. As expected (since we're in a singly-threaded environment), the function's return value indicates that the current value of the destination agrees with the comparand's value, and that the exchange was successful. However, the value that actually gets stored at the destination address is bizarrely corrupted, and does not agree with the exchange value. Can anyone offer any insights (other than a suggestion to upgrade to VC++ 2005)? Maybe someone knows of the assembly code used by the current compiler's intrinsic?

    - Send/Post Messages on Vista Hi all, There're two apps, A and B on Vista. Using FindWindow() with caption of a window, it proves that B can find the window of A. However when B calling PostMessage() to shot down A of the window, it doesn't work. My understanding is that both A and B are in the same session since they are running under the same user login. Does this mean that both SendMessage() or PostMessage() will not work anymore even in the same session on Vista? If not, there's a way to implement this, better off without any dialog pop-up for user's interaction? Thanks, DH Tag: How to modify the time and/or date of a file? Tag: 265681

    - rs232! Hello, As I read the following document a few times at: http://www.codeproject.com/system/serial.asp given to me by fellow friend Jochen in my previous post I am ready to give rs232 a crack at it! :) I am using the "Windows messages" option of rs232 interfacing (See document). In spite of me using VC++ for 9 months now, I still consider myself a beginer when it comes to much of the language and especially the VC++ GUI. Here is my first problem. I have started to code for the rs232 as indicated in the above link's web document as so: #define STRICT #include <tchar.h> #include <windows.h> #include "CSerialWnd.h" I still don't know what the "#define STRICT" statement is doing there? But I am just copying the sample. Given the above include statements I get the following error at build time: c:\_DTS_PROGRAMMING\C_PROGRAMMING\vc++\MY_APPS_LAB\RS232Test_XPPLC\WndProc_CW1.cpp(20): fatal error C1083: Cannot open include file: 'CSerialWnd.h': No such file or directory In the document, it clearly states that I need to include the serial class header file, in which I did, and I must make sure that the header-files of this library are in my compiler's include path. Up to now all I am used to is including windows.h and some odd header file that I created. I don't know how to include the header files of CSerialWnd library in my compiler's include path. I didn't get very far, but its a start and I don't know what to do, I tried to look at the project properties to see if there is a field that requires include paths, or something like this.... I would appreciate any guidence or direction towards this! Any help is very appreciated! Thanks -- Best regards Robert Tag: How to modify the time and/or date of a file? Tag: 265672

Is there a preferred, simpler way to do that?

You need to open the file with CreateFile first, then SetFileTime would
work. In that other post, you've never opened the file.
