I was looking for a C++ library for use as stated in the title. I was considering using Voce; however, for the project, I wanted to be able to use a custom voice. For example, in most TTS programs you can pick voices. I wanted to record a custom one. However, I don't really know how these libraries work internally, and since the text to speech is referred to as synthesis, it seems they are created through algorithms rather than recordings. Is there any library which I could use a custom recorded voice with?
#include <iostream> #include <string> #include <vector> #include <map> const int ENUM_NOT_FOUND = -1; const std::string NEW = " "; enum Day {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday};
[code]....
Ouput with GCC 4.8.1:
Monday Tuesday Wednesday Thursday Friday Saturday Sunday Name a day: Friday day = Friday
But the problem is that whenever I define a new enum, I have to define the << and >> overloads for the new enum again. Isn't there a way to template that as well, so that the << and >> overload needs to be defined just once? My atttempt:
fails to compile. I guess the problem is Enum is not known at compile time, even though it should be deducible during run time? Error mentions ambiguous overload for operator>>.
I'm working on a Fraction Class assignment where I'm supposed to provide conversion operators to allow Fraction objects to be used in expressions containing float data values. The way I have it now, I'm getting an error that says operator float(const Fraction &) must contain 'void', which makes no sense to me. Lines 155 - 173.
// Fractions CLASS // Source: Fraction2012.cpp // Author: Warren H. Knox, Jr. // Date: 11/8/2012 #include <iostream> #include <cstdlib> using namespace std; class Fraction {
The problem is that I want to write a C++ program that converts an ordinary text file into binary and then reads that binary file and converts it to text file so that this text file equals to first text file. I have wrote this code for it.
int main() { string name1 = "first", name2 = "sec", name3 = "third"; int j = 0, k = 0; ifstream ifs(name1.c_str()); // Here I want to read from the ordinary text file (name1).
[Code] .....
Now what the ofs.write(as_bytes(j), sizeof(int)); or ifs.read(as_bytes(k), sizeof(int)); exactly mean?
In practice, the file name1 contains digit 5 and its size is 1 byte. The name2 contains some character/sign like [] and its size is 4 bytes and name3 contains digit 0 and its size is 1 byte, why? I before have created the name1 file in ordinary text file mode.
My machine is Windows 7 32-bit. My compiler is MVS 2012.
How to convert an ordinary text file into binary and how to convert that binary file back to a text file so that the first text file equals with the last text file?

In my class I'm trying to display the elapsed time as my label on a windows form. I've been reading up on all the different articles online and have tried these three methods all with the same result:
1. Using the System.Timers class 2. Built in Timer sub-class 3. Defining directly inside of my class the StartTime, etc. variables.
All of these still result in the following error: Cross-thread operation not valid: Control 'User_Interface' accessed from a thread other than the thread it was created on.
Currently, my windows form is being called by another class, but I'm not sure if this is the cause of the problem.
This is a sample of the code that I'm currently using to show the elapsed time:

"Control does not support transparent background colors"
How do I detect left mouse button down and up events on the 'Close' option of the system menu that appears when the mouse is clicked on the top left corner of a form?
I am busy with a project, it is going to consist out of 3 different windows which is logic enough for this whole code to be interactive.
It must be able to pull data into a windows form, displaying it into a textbox, and when you click on the textbox it needs to open up another window where you will have a windows form that will display data as the code loops through the questions in the database.
I am not sure how to push the data that has been selected on the database to the next window..
Here is my code for the first window:
; namespace WindowsFormsApplication1 { public partial class Form1 : Form { //SqlConnection myConnection = new SqlConnection("Data Source=(local);Initial Catalog=KnowledgeEssentials;Integrated Security=SSPI"); //int intType = 0; public Form1()
[code].....
With the second window the data in the table needs to be displayed and each row from the table needs to have a checkbox next to them, so that if the check box is checked, the relevant information of the checked row will show up in the 3rd window... so MY question is, HOW do I pull that data from that specific database and let it show in the listcheckbox?
This is my problem in my subject programming but i dont how to use Array in windows form ... If i run my code i want my Data in listview would not be disappear if i close the form ...?
