 | >>while(desktop = NULL); That will produce an infinite loop because you want to use the boolean == operator, not the assignment = operator. And what's the point of those do loops anyway? If FindWindow() returns NULL the first time it will always return NULL. Calling FindWindow() again isn't going to …  |
| | you can not just typecase from char* to wchar_t*. You have to call one of the transformation functions. This works ok for me when the program is not compiled for UNICODE [code] #include <iostream> #include <cstring> using namespace std; int main() { char S1[] = "C:\\Program Files" ; char S2[]= … |
| | you have to use some of the [URL="http://msdn.microsoft.com/en-us/library/ms682073(VS.85).aspx"]Windows Console[/URL] functions. But they are not available if you are using an ancient 16-bit compiler. If that is true then upgrade to a new free 32-bit compiler, such as Code::Blocks or VC++ 2008 Express. |

| | add something to the end of the program that makes you enter a key, such as cin.get() -- btw the problem is your program, not the IDE.  |

 | you don't need a loop or switch statement. use string's substr() method to extract the first two characters and again to get the last two characters. |
| | what code are you talking about? |
| | You have to compile all programs for release mode before attempting to run them on other PCs. The DLLs you mentioned are for debugging on your PC only with your compilers. |
| | you can use the macro isdigit() to find out if it is '0' to '9'. And the At() method is unnecessary. [icode]if( isdigit(word[i]) )[/icode] |
| | Re: Idl compilation I think it doesn't know what [b]string[/b] is, and I don't think you can pass string objects as parameters to COM functions. Change [b]string[/b] to [b]char*[/b] and see if that fixes the problem. >>What does "in" mean in your function by the way? In COM programming there are [b]in[/b] parameters, … |
| | Have no idea how to help you because I don't know what Multiply() and Power() do. And that is one of the weirdest programs I have seen in a long long time. [b]program_body[/b] instead of [b]int[/b] ??? Only a university professor would dream of writing such confusing and unconventional crap. |

| | There is no such concept as HttpSession in c++. When you logon in java I presume the java code checks a database, such as MySQL, for login credentials. If username and password are verifyed then the user is allowed to continue using the program. C++ programs can do the same … |
| | [QUOTE=Tom Gunn;894029]. "rt" isn't portable.[/QUOTE] Whatever gave you that idea? True, text mode is the default, but there is nothing wrong with specifying 't' in the mode string. If there was then it would be in the c standards.  |
| | I assume you mean in MS-Windows operating system. You would not want to do that even if you could because it would not allow the user to easily select a different desktop icon, the start menu, or any of the icons in the desktop trey. And that would piss off … |
| | Are those four different integers? Looks like a normal text file to me, not a binary file. If it were binary file then you wouldn't be able to read those integers. Try this: [code] int x; infile.read( (char*)&x, sizeof(int)); [/code] or this [code] char* buffer = new char[4]; infile.read(buffer, 4); … |
| | There are several ways to accomplish that -- functions in stdio.h or iostream. For example: [icode]cin.get()[/icode] |
| | Reading that file is not difficult as long as the records are separated by '\n' or '\r\n', depending on the os. The code below will read each line then split it up with the semicolons as deliminators. [code] FILE* fp = fopen("file.txt","r"); char buf[255]; while( fgets(buf,sizeof(buf), fp) != NULL) { … |

| | since ptr2 is a reference to ptr1, when you change ptr1 the change is also reflected in ptr2. What you can't do with ptr2 is assign a new value to it like [icode]*ptr2 = 2;[/icode] is an illegal statement because ptr2 is a const. |
| | Re: Anonymus Structs >>reinterpret_cast is the recommended way over anonymous unions. reinterpret_cast is not allowed in C. So I don't know where you got your information but its wrong. The only place I've used anonymous structs is inside a union [code] union something { struct { int x; int y; }; unsigned char … |
| | compile both for debug and use your compiler's debugger to find out the problem. Does your program use LoadLibrary() to load the dll into memory? Then GetProcAddress() to get pointer to a function? Make sure that function pointer is not NULL. |
