Hello all, I have some questions about the windows console. If my main GUI windows create a new console windows attach to the main process by calling AllocConsole(). Is there any way to get notify when the console get closed by the user? For example, the close windows button in the top right get clicked by the user. The problem what I have is that if the console windows get closed, then my main process will also be terminated. However, it happen without letting my free my application resource. Any suggestion? Thanks for advance! Nachi

Hello, I am planning to write a program that will do string find and replace for any text file. Can anyone one give me any suggestion what is the best way to do it, or is there any existing library already provide this feature? I can write my own but it may not be efficient enough. Any suggestion? Thanks! Nacho

Is this the only way, since I have a lot of other files have similar problems, is it means that I need to re-save all those files? Thanks!

When I try to compile my old code in Visual C++ 2005, I get the error message error C2990: 'Cg2HashTable' : non-class template has already been declared as a class template with the code //*************************************************************** // Forward declarations template class Cg2FixedList; template class Cg2HashTable; template class Cg2SortedList; //*************************************************************** class Cg2DataHandle { private: friend class Cg2FixedList; friend class Cg2HashTable; friend class Cg2SortedList; ............... How can I fix this? Thanks!

Hello, Can anyone tell me which function I can use to delete all file in a folder. Any standard ANSI C++ function I can used? Thanks!

Hello, I would like to know what is the proper way to use LoadLibrary() when loading DLLs. In my project, it depends on couple DLL files to run. Those DLLs need to sit in Windows\win32\ or the same folder as the executable file. However, I want to put those DLL filew into some fixed place and when my application starts to run, I can load them to the memory. I try to use LoadLibrary() function but I don't know where should I call this function in the code. It is because everytime I start the program, I already get the "missing dll" error and the program get terminated before any code has been run. Any idea about this? Am I missing something? Thanks!

Thanks, but is there any way which just use ANSI C++ standard type rather than BYTE? By using BYTE, we will have problem when we port the code in other platforms. Any idea? Nacho

Hello all, I have a question about doing an increment of a Void* pointer. I find out that I cannot do something like this int i[10]; void* p = i; int j = *((int*)(p++)); The compiler will complain about the size of the pointer when I try to do an increment. My alternative approach is int i[10]; void* p = i; int j = *((int*)(((char*)(p))++)); // Ugly First, I type cast the void* to char*, and then the compiler will know when I do the increment, it is going to add 4 bytes each time. I think this approach is ugly and might not compatiable with different platforms (when char* is not 4 bytes). In case if people wonder why I try to do something like this is that I try to calculate the offset in an array by my self with only know the size of the element in the array in the array. However, I don't know how to add exactly n byte to a pointer when calculate the offset. The default increment behavior always requires to know the type of the pointer, which I don't know. Any idea? Thanks! Nacho

For the array, in order to use the heap memory, you can allocate your array like this float* floatArray = NULL; floatArray = new float[100]; and when you finish using your array, you can delete [] floatArray; floatArray = NULL; I wish it help! Nacho

Hello all, I am writing an assert function and don't know how to do certain things, 1. How can I know the file name of the code that cause the assert? 2. How can I know the line number of the code that cause the assert? 3. How can I know the function name of the code that cause the assert? 4. How can I print out the call stack when I get the assert? 5. Can I get the PC and SP register information when I get the asset? Thanks! Nacho

Hello, Can someone give me some explanations how C++ actually doing the type casting? Is a Dynamic Cast really expensive? What about Static Cast, Constant Cast and Interrupter Cast? Thanks! Nachi
