| | b is a pointer to a vector, not to a Matrix2. vector's don't have transpose() method. `myMtrix2[0].transpost()` may be what you want. Or if you want to call that method for each Matrix2 in the vector for(auto x : myMatrix2) { x.transpost(); } The above requires c++11 compiliant compiler, and …  |
 | move lines 43 and 44 up between lines 40 and 41 so that they are within the if statement that start on line 27. The way it is now you are re-writing the struture whether it needs to be changed or not. Only write the structure if something has been … |

| | >>Is there a fix? Yes -- don't install that on Vista. Most old compilers don't work very well, if at all, on Vista. The good news is that you can download the newest version VB 2008 Express free from [URL="http://www.microsoft.com/express/vb/"]here[/URL]. |
| | More than likely the same problem as other very old compilers, such as vc++ 6.0. Upgrade the compiler -- VB 2008 Express is free, but I don't know if that version will do what you want it to do. |

| | Re: ~Error~ Is that in response to a program you wrote? What compiler did you use? there are many ways to figure out where the problem lies -- one way is to put a bunch of print statements everywhere so that you can see where the program stopped when the error message … |

| | Your program is doing way too much work! There's an easier way to do it. The code below does NO error checking so you might want to add that. ifstream myfile("CS DataSet.txt"); std::string line; int nums[20][5]; int row = 0; int col = 0; while( myfile(line,',') { nums[row][col] = atoi(line.c_str()); … |
| | start out simple. First just write a progam thad declares an array of 20 floats. The expand the program to fill the array with 20 values. Once you get that done and tested you can continue the problem a little bit at a time. This is called "divide and conquer" …  |
| | Just get the port number from the user then format a string, something like this. The code may not be exactly correct, I didn't test it. int port = 0; cout << "Enter port number\n"; cin >> port; stringstream str; str << "\\\\.\\Com"; str << port; CreateFile(str.str(), ... ); |

| | Re: Expression I would think `ab^4c^2-d/m-n` would be interpreted liks this: where ^ is power operation `a*(b^4)*(c^2)-(d/m)-n` In none of the math courses I took (or recall) did ^ represent bit operation. I only learned that when studying computer programming. |

 | You're talking about MS-Windows, right? You can easily get the file info in a C program (or another language) by calling win32 api function [FindFirstFile](http://msdn.microsoft.com/en-us/library/windows/desktop/aa364418(v=vs.85).aspx)() and [FindNextFile](http://msdn.microsoft.com/en-us/library/windows/desktop/aa364428(v=vs.85).aspx)(). They both fill in a structure that you pass to the functions that contains all the data. You can rename a file by … |
| | Re: Strings in C declaration of character arrays in C is like this: `char var1[] = "1F 19 03 04 09 18 10"` Or if you want a pointer instead of an array `char* var1 = "1F 19 03 04 09 18 10"` There are several ways to convert "1F190304091810" to "1F 19 03 … |

| | ptr[i] is not a pointer, so you need to use the dot operator . SetState() only needs one parameter, now twom In main() you would write this: for(int i = 0; i < 100; i++) A[i].setState(n); And setState() simplifies to just one line void State::setState(int num) { *state = num; … |

| | Is Dict storing just the pointer address passed to it by addWord()? If yes, then that would explain why passing string literals such as "dog" and "cat" works while passing a character array doesn't. Dict needs to duplicate the string within the class so that the class has it's own … |

 | move the function starting on line 28 into a \*.cpp file -- you can't put executable code in header files because the compiler will duplicate the code in each \*.cpp file that uses the header file. |
| | that doesn't work if your program does not have a message pump. I've never tried it in a dll but I do know it doesn't work in a standard C/C++ language console program. You might want to write a small C windows program that tests your dll to see if … |
