• DreamState converting address to string

  How can I veiw the address of a location, that is to say how can I convert an adress to a string or some other type Given: int i(99), *pi=&i; You can output the address directly using: std::cout << i << ' ' << pi << '\n'; Or you can convert to a string using ostringstream as in: std::ostringstream ss; ss << pi; std::cout << ss.str() << '\n'; Another way to convert to a string is _ultoa or _ultoa_s, but this does not provide leading zeros: char Buffer[16]; _ultoa(reinterpret_cast(pi), Buffer, 16); std::cout << Buffer << '\n'; thank you for taking the time to anwer my question, but when I try to make a ostringstream ...Show All

• cmazur Keep Visual studio 2003 from crashing when trying to load symbols from vista.

  Ok, i recently came accross the following issue. My work has not switched to vs2k5 yet, but i needed to do some debugging on vista. Except that every time i forgot to remove the symbols server path from my symbols directory(same thing would happen if you had vista symbols installed locally too) my ide would crash when it attempted to load up the symbols. The cause There was an operation being done something to the effect of this. foo(int iIndex) { if( iIndex < 16 ) g_ErrorTable[iIndex]; } .. why is this bad well because the ide was accessing invalid memory when the iIndex was a large negative number. The fix this one is pretty easy. goto your vs program files directory, common7\packages\debugger, and copy ...Show All

• Tilfried Weissenberger Creating a DLL - Translation between 2 DLL's

  Hi, I'm not particularly experienced with C/C++ but I have a problem: I currently have an application, which uses lame_enc.dll to encode audio into MP3 files. There is another encoder available as gogo.dll which uses ASM hand-optimised routines, and is therefore much faster. Without modifying my application, I want to create a new lame_enc.dll file which will simply pass data onto gogo.dll, and translate any settings required. Therefore giving the option to add a much faster encoding engine into my application. The manual for gogo.dll is here http://homepage1.nifty.com/herumi/soft/gogo2/man/ (no source code is provided) lame_enc.dll manual is available here: http://www.fi.muni.cz/~qruzicka/Smid/man.htm Source for lame ...Show All

• pst_grant modal dialog box not closing quickly enough

  Hi. I have a single threaded MDI application with several windows that are concurrently open and displayed during normal operation. I need to print the contents of a user-selected window. Per end-user request I display a CDialog based modal dialog box that allows the user to select the window he wants to print and then click on the OK button. I have code that then takes a bitmap snapshot of the requested window and prints it to the printer(from KB article q186736). So far so good, but if the dialog box overlaps the window that the user wants to print, the overlapping part of the dialog box is also printed. This doesn't make sense to me - the dialog should completely go away as I understand it. FWIW here's a code snippet: ...Show All

• criquety list of default libraries being pulled in

  Is there a way to get a list of the .lib files that will be searched for when you have "Ignore All Default Libraries" set to No in the Linker/Input properties grid /VERBOSE is... well... a little too verbose. There is way too much output. All the searched libraries are listed multiple times. For example, kernel32.lib is listed 6 times. To obtain a list of individual libs I would need to go through the entire linker output and try to keep a list of each library name and whether I have seen it before.

• Quentin Mayberry STL Thread Safety

  So, I looked for STL thread safety, and there are only two hits:  One in Visual C++ Express Edition , and the other in Visual C# Language . Where's the best place to discuss MSVC 2005's STL thread safety -MM Two things have to happen here: 1) The C++ Committee has to decide on what the best threading model for C++ is - this is by far the largest single work-item that is currently under-discussion for the next revision of the C++ Standard. 2) Once the overall threading model has been decided then it needs to be integrated into the rest of the C++ Standard - and by this I largely mean the Standard C++ Library. For the containers what I suspect will happen is  that there will be a sepa ...Show All

• Pockey How do I generate an assembly file from my C++ code?

  Hi! As I am an Electronics Engineer, I have worked on some embedded systems, and feel very comfortable with assembly code when I have to make a certain part of my project more efficient. I understand the way we can use inline assembly code in C++ too. But, to learn the way Microsoft C++ compiles the code, I would like to have a look at the assembly code. So, is the assembly code generated automatically every time (if it is, I haven't spotted the file), or is there some way I can create the file PS: I know that while debugging, I can view the assembly, but that's not what I want. Thank you, Anup. Use the /FA compiler option . ...Show All
