    - Structure size I would like to allocate a structure size of 1024 bytes but I want the compiler to do the calculation for me. typedef struct { int var1; short var2; long var3; char var4[ ?????? ]; } MYSTRUCT; What I want to do is replace the ?????? something that will automattically make the total structure 1024 bytes without having to manually count the bytes of the other members myself. Is that possible in vc++? Thanks. Tag: MMX registers Tag: 279273

    - Petzold's tome hey all, i started my reading of Programming Windows and have a newbie question about the following excerpt: Microsoft Windows version 3.1 was released in April 1992. Several significant features included the TrueType font technology (which brought scaleable outline fonts to Windows), multimedia (sound and music), Object Linking and Embedding (OLE), and standardized common dialog boxes. Windows 3.1 ran only in protected mode and required a 286 or 386 processor with at least 1 MB of memory. The last sentence is my question what does that mean in lamen's terms to run in protected mode? thanks, rodchar Tag: MMX registers Tag: 279259

    - Compiler optimization problem in MSVC 2003 Release mode Hi, I have written a small function to check whether a single precision variable is sufficient to hold a double precision value. The code is below #include <stdio.h> int cmpFloat_to_Double(float x, double y) { return x == y;} #define IsSinglePrecisionSufficient(a) cmpFloat_to_Double((float)a, a) void main( void ) { double b = 0.7; printf("%d",IsSinglePrecisionSufficient(b)); } It works fine in debug mode giving output of 0 but in release it gives 1. Also if i change int cmpFloat_to_Double(float x, double y) { return x == y;} to int cmpFloat_to_Double(volatile float x, volatile double y) { return x == y;} it works fine in release mode too.

    - How to include a header file in another header file that.... Hello, I have a global header file called TypeDefs.H, this file is included in header file of every class of my project. because all classes use custom types. Now I have a class called CMyData which is also a member of some structs in TypeDefs.H, so I have to include MyData.H in TypeDefs.H problem is some members of CMyData are custom and defined in TypeDefs.H so I also have to include TypeDefs.H in MyData.H I agree that it may seem ugly but in this way I can keep things organized in my brain, but compiler dose not like that and shouts loudly with thousands of error messages. I even tried to use <code> #ifndef MY_DATA_H_ #define MY_DATA_H_ ... #endif </code> in MyData.H and <code> #ifndef TYPE_DEFS_H_ #define TYPE_DEFS_H_ ... #endif </code> in TypeDefs.H but problem persists can someone kindly tell me how can I get over this problem:) Tag: MMX registers Tag: 279231

    - Function Identifier Not Found Error Hi, I was trying to compile some code and I am getting a "Function identifier not found" error. I can't figure out why since the function that it claims is not identified is very clearly laid out. Here is the declaration in my h file: #pragma once #include "afxwin.h" class CGUIDlg : public CDialog { // Construction ... // Implementation protected: .. public: BOOL processEventMsg(time_t TimeSec, UCHAR chan, int strtID, UCHAR *buf, int siz); ... ... }; My function is written in the code as: BOOL CGUIDlg::processEventMsg(time_t TimeSec, UCHAR chan, int strtID, UCHAR *buf, int siz) { ... } And it is called in another function as: void getAllRs232( int lr ) { ... processEventMsg(TimeSec, (UCHAR)(lr+8),elmThree*32, adrs, length-1); // These variables have been declared and used ... } However upon compilation the error states that processEventMsg identifier is not found. I've tried moving around the function to different area of the code but it gives the same error. Does anyone have any ideas about what could cause this? Thanks very much in advance for any help!

    - Question about TCHAR string Hi, I've been spoiled with C# and the easy to use string functions. Now I'm into a bit of C++ for writing a custom action for a DLL to be incorporated into an MSI installer. Yikes. What I'm basically doing is getting the Product Key from the MsiGetProperty() function, like this - TCHAR szPidKey[MAX_PATH]; DWORD dwPath; dwPath = sizeof(szPidKey) / sizeof(TCHAR); MsiGetProperty(hInstall, TEXT("PIDKEY"), szPidKey, &dwPath); So I have my Product ID in szPidKey. Now I want to do some manual verification of it. The Product ID is of the form - 123456789-ABCD-12 I need to verify this code so I need access to the beginning part (123456789) and the end part (12). So I'm looking for a way to substring out those parts of the string. I'm also looking to convert those substrings into integer or long data type so i can do some checking on them, is it ok to use itoa to do that? Thanks very much for any hints.

    - redirecting cout - is it possible with dynamically loaded DLL? Folks, I am redirecting the standard output from my console application to a log file. Dynamically loaded DLLs seem not the see this redirection, and still echo on the console. Here is the sequence of events in more detail: 1) Starting console application from the command prompt. 2) The application loads a shared library using the "LoadLibraryEx" function. The library is loaded and correctly executes an initialization routine. 3) The console application now redirects cout to a new file. The (simplified) code used to achieve this is as follows: log.open(x.c_str(), ios::out); cout.rdbuf(log.rdbuf()); 4) Logging statements in the main application (coded with "cout <<") write to the new file, as expected. Logging statements in the shared library (also coded with "cout <<") continue to be logged to the console, which is not what I want. Switching the order of steps 2 and 3 doesn't change the behavior. The code does work fine when running under Linux. Is the above behavior expected? Or, am I missing something? Any solutions or alternatives? All input greatly appreciated, Johan Tag: MMX registers Tag: 279105

    - MessageBox question When I'm using the MessageBox() function, user can still click on the window below it to ignore the messagebox. Is there anyway to make the message box kind of mandatory? (can't be ignored unless clicked ok.) Thanks, Alan Tag: MMX registers Tag: 279013

I was just wondering if there is a way to tell Visual Studio to use
the MMX registers to improve performance.

Thanks.

No, there is no way. You will need to write a code by
yourself. However, there is /arch compiler option, which
will instruct a compiler to use SSE/SSE2 instruction set.
