• Tigerwood2006 self-made hashtable extremely slow compiled with VC2005

  Hi, I have a problem, and at the point I'm clueless what to do. The problem is, my app becomes extremely slow when compiled with VC2005. Application runs in half hour when compiled with VC6 or VC7, but now, compiled with VC8 it seems to take several days. I'm having this homebrew hashtable implementatation because of portablility reasons, whose probes seems to consume most of the cpu -time according to profiler. It takes 40% of cpu, while normally its something like 1%. But because whole execution time jumps several hundred percents, this alonr doesn't explain it all. And weird enough, simple little timer app I made to test the hashtable runs just fine. I'd be happy to stick with VC7, but I need to have 64bits becouse of memory consumptio ...Show All

• Steev Remove a given value from a list

  Hello all: Is this solution correct void remove(Node **node, int v) { while (*node) { if ((*node)->value = v) { Node *tmp = *node; *node = (*node)->next; free(tmp); } else node = &(*node)->next; } } If this code is correct, I have the following question: why can we just free(tmp) without making the collection between the previous node of tmp with the node after tmp Thank you Yes, it is correct. As for your subsequent question: if you don't connect the previous node with the node after tmp you will end up having previous node having a 'next' pointer that points to freed memory instead of pointing to the next node ...Show All

• wazimu VS2K5 SP1 Beta bugs!!!???

  I installed the beta to get around a merge problem with TFS and it worked. However, I create the installer for our product on that machine. When I released daily installer the code started breaking because the actual code was compiled with RTM VS2K5(this is expected) However, our previously released products running on MFC 8.0 all started breaking after installing the daily build. Why would already installed products on a system break if a product installed with the beta MFC merge modules start to break Is this what will happen when the SP ships And more importantly, how do I scrape the unwanted SP1 Beta DLLs from these now "infected" test machines Thanks, This bug is already reported on connect.micro ...Show All

• amendez sytem invaded?

  For the past couple days ever since downloading MSVC++ Express Edition, we have been getting warnings when we try to log into hotmail, that the connection may be being monitored... I have no reason to think that it is from this MSVC++ software but when I log into this forum I have to use a hotmail account to log in.. We also have the K9 web-protection software installed and it has been saying that someone used Shareaza, when we do not have any peer to peer software installed on our machine. How is this possible Is there a way to fix it, if someone is breaking in We use AVG for av software in conjunction with ZoneAlarm.

• pinoyz I met a weird thing when using fwrite() and fputc()

  I am using VS 2005. In a project when I was trying to write some unsigned char into a file, I used fwrite() and fputc(). But I found whenever I tried to write 0x0a, fwrite() function automaticly wrote 0x0d before 0x0a. So I wrote a small test to test it. Here is it: FILE* file; unsigned char p = 0x0a; long offset = ftell(file); // here the offset = 0; fwrite(*p,1,1,file); offset = ftell(file); // after this, the offset = 2. and in the file I // found 0x0d and 0x0a was written. I can't understand. I just want to write byte by byte, automatically inserted byte 0x0d will cause problems in my project. can someone tell me what is the cause and how to avoid the unwanted byte ...Show All

• ahmedilyas Problem usage CImage and Clipboard

  When I do this, I got ASSERT inside CImage::ReleaseDC(), What's wrong HBITMAP hBitmap = (HBITMAP)GetClipboardData(CF_BITMAP); CImage m_CImage.Attach( hBitmap ); CWnd::OnPaint() { CPaintDc dc(this); CRect rect; GetClientRect( &rect ); m_CImage.Draw( dc.m_hDC, rect ); //ASSERT inside! } Thanks gdrivas. I fixed this problem- Detach has never called. michot hi, You should propably provide more code, so we would be more accurate of what is happening. There are many cases of the error's reason: - first if the program executes two times the 'm_CImage.Attach' without execute the 'm_CImage.Detach', assert occurs. So you must be ensure that 'Attach' 'Detach' exeuted in pairs. - Then provid ...Show All

• tribal Multiple inheritance and function overloading

  class A { public : int f() { cout<<"A::f()"; } }; class B { public : int f(int i) { cout<<"B::f(int)"; } }; class C : public A, public B { public : int g() { f(); } }; Why does the above program give following error error C2385: ambiguous access of 'f' in 'C' error C3861: 'f': identifier not found, even with argument-dependent lookup Where is the concept of function overloading and method signature go PS: The above program code compiles if you give A::f() inside function g() Right .. so in this case function signature is different int f(int) ; and int f() ; so when u call f() it should be ideally be invoking int f() i.e. without an ...Show All

• el_Fede strange output with atan2.....what does it mean?

  my line of code is: phi=atan2(n,e.x)+atan2(e.z,e.y); and it returns this: 0012FCE43.14159 does anyone know what this output is thanks! -sharyl i found the problem: i was writing file_op << phi << file_op << ........; instead of: file_op << phi ; file_op << ........; thanks for all the help! Yep. That'll do it. operator<< on objects tend to output their memory addresses. Since file_op is on the stack, you got its address. yeah, i know......i was thinking it was some type of notation signifier.....like scientific or somthing, but i couldn't think of what FCE would be short for......and if you notice PI shows up ...Show All

• RMORAR About obj file for VC8

  I use VC8 lately.It's build some obj files for a project,but I don't know what's the obj file type.It's not COFF file and not OMF file. I use new dumpbin tool to check these obj file, the report show:"ANONYMOUS OBJECT". Who know what's the file type Pleaes help,thanks... You probably specified /GL compiler flag, i.e. you are using link-time code generation. In that case object file contains internal representation of your program, something resembling abstract syntax tree. That format is not documented anywhere and there is no guarantee it will not change in the next VS version.

• yousaid CStringT::Tokenize

  The behaviour of Tokenize has changed between MFC 7 and MFC 8 and has broken some of our existing code. The change has to do with passing in an empty ("") delimiter string. In MFC 7 Tokenize would return the original string AND adjust iStart so it was possible to use it in a while loop like so: CString strDelimiters = "" ; int iStart = 0; CString strCurrentValue = strText.Tokenize( strDelimiters , iStart); while (strCurrentValue != "" ) { //DO SOME STUFF HERE strCurrentValue = strText.Tokenize(strDelimiters, iStart); } With MFC 8 iStart is never adjusted so subsequent calls to Tokenize always returns the original string rather than returning an empty string lik ...Show All
