C :: Program Terminates Without Message
Jan 15, 2014
I'm trying to parallelize bottom's up merge sort algorithm. Firstly, i must have working procedural code.
I rember I had my code working last week but I made some changes ( probably to arguments passed to sort function ), i run my program several times without rebuilding it so i though it's still working.
Now i came back to my code and my program terminates without any message which confuses me. I debbuged merge function and it seems to work well, at the end i have sorted array.
fprintf doesn't print any value to my stdout.

I am trying to do a while loop that terminates the program when 99999 is entered but otherwise allows infinite integers to be entered. My problem is that when a negative number is entered it crashes and also when I enter a number it displays it twice.
#include <stdio.h>
#include <stdlib.h>
main() {
int number;
printf("Input an integer.
"); do {
scanf("%d",&number); /* read a single integer value in */
printf("%d
",number);
} while (number != 99999);
}

I want to be able to type a message into another program (such as notepad) using C++. How would I do that? Is there a function to do this, or an event, or something?

I am writing a porgram which includes encoding and decoding a message.Now I am doing the encoding part.
The goal is to encode a message using similar approach as Caesar Cipher. But instead of alphabets, I am going to use the entire ASCII code of total 128 codes to be the base.
And it is not a simple shifting, it is a rotation. This means if you want to shift 4 units from char <DEL>, it will come back to the first code in ASCII Code which is at dec 0 char <NUL> and starts the shifting again. It won't jump if the limit of ASCII Code is reached.
Here we've got 7 different malls' names and I am going to encode them with a shift n. I think n is free to set, so here I just set it as 5. This is also called the key.
I have written something and I think it should work, but after all it doesn't. And I don't get what is wrong.
Here is my program:
#include <iostream>
using namespace std;
const int NUMBER_OF_MALLS = 7;
const int MALL_NAME_LENGTH = 13;
const int NAME_SIZE = MALL_NAME_LENGTH + 1;
void encode(int key, char plain[], int length, char encoded[]) {
for (int i = 0; i < MALL_NAME_LENGTH; i++)
[code].....
Note that I am not going to use other libraries, just <iostream>.

I need to have a program display an error message if the variable entered isn't an integer but then I want it to cin again. I have this but it doesn't work:
cout << "Enter an Integer: " ;
for (;;) {
cin >> var;
if (!cin) {
[Code] ....
I am not sure how to do what I want and this doesn't work, it just repeats That wasn't an int.. over and over again.

I am writing a program to auto login in a web site. Before making next attempt I have to wait for some time like some 10 seconds(it is configurable). But during waiting UI should not freeze. I wrote code something like this. Here event m_hEvent[1]) will be set by another thread after 10 seconds.The problem is UI still freezes some times!
while(1)
{
//m_hEvent[1] will be set by another thread after 10 seconds
dwRet = MsgWaitForMultipleObjects(1, &m_hEvent[1], FALSE, dwMilliseconds, QS_ALLINPUT);
ResetEvent(m_hEvent[1]);

I'm getting an error message that I can't seem to fix. The error clearly states that during the link aspect of the debugging and build there is an error that says that the stdio.h file is either missing, invalid or corrupt. When I try to program using any of the other headers I'm getting the same error. The files are there I can see them in the include folder, so I'm asking what can I do to fix all these headers and beware I am a beginner at programming and using any kind of compiler.
This is the error I receive.
1>------ Build started: Project: hello, Configuration: Debug Win32 ------ 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped =========
This is the compiler I am required to use for an online course and all instruction is given for the Microsoft visual 2010 express edition. Also the only file I think that's being referenced is the #include <stdio.h>.

I have a simple dialog based app that performs some time consuming file manipulations. The activating method contains the customary
Code:
CWaitCursor wait;
The hour glass initially appears, than after a few seconds, the dialog title bar indicates 'not responding'.
This is misleading to users as it suggests the application has ceased to function when, in fact, it's working just fine. I would like very much to eliminate this 'not responding' message but havn't a clue how to do it. Have any of you dealt with this problem, if so, how?

I am having trouble finding the solution to printing the contents of a variable. Here is my code:
void OnSize(HWND hwnd, UINT flag, int width, int height) {
std::wstringstream ss (std::wstringstream::in | std::wstringstream::out);
ss << flag;
std::wstring myStr = ss.str();
MessageBoxW(hwnd,myStr, L"Window Resized",NULL);
}
Note, I have #defined UNICODE at the beginning. The compiler tells me this for myStr.
std::wstring myStr
Error: No suitible conversion function from "std::wstring" to "LPCWSTR" exits

First of all i create single server single client program and then using thread i make multiple client to connect to server.
while(true){
csock = (int*)malloc(sizeof(int));
if(nClient<=maxClient){
if((*csock = accept( hsock, (SOCKADDR*)&sadr, &addr_size))!= INVALID_SOCKET ){
[Code].....
The clients send message to the server and server echo back the message to that particular client. But i want that the server will echo back ones's message to all clients. Suppose 5 clients are connected to the server. So whenever one client send a message to the server, the server will send that message to all 5 clients.

Is it possible to edit the message map at startup instead of just having it set at compile time?
I'm reading some values from an XML file at startup. The menu options will be determined from what I find in there. But I need to assign those menu options to the message map.

I would like to have my program pause at a certain screen but not to have the "Press any key to continue..." message or the press of a button. In my program, the code looks similar to this:
for(;;)
{
cout
cin
cout
cin
...
//
here, I want to have a pause to view what the for loop has come up with but to not have a message display or a button press needed. At the end of the loop, I want it to pause before looping again. IS this possible?
If so, how can I implement it into my program?

Basically I wanna make my textbox to contain only positive numbers. I was able to do that via masking and regex. I should let you know that the column is bound to a variable which is an int. Therefore, the user always have to type an int (no letters or characters). Like I said, I have been able to prevent user from typing anything but numbers.
Now to the problem:When the user leaves the cell blank and chooses to get out of that cell, they'd get "Input string was not in correct format" next to that cell.
-My approach is: whenever there is nothing in the cell, just replace it with 0. I have code that I thought will do that, but it wont. Seems like the cell was not null, because the if clause won't execute. This is the code:
private void gridView1_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e) {
GridView view = sender as GridView;
if ((view.GetRowCellValue(e.RowHandle, colPriority).ToString() == "") ) {
list.ElementAt(this.gridView1.FocusedRowHandle).priority = 0;
}
}
-Another approach is to change the display or the error message to like "Please enter a number." I have tried doing this but no luck. When I try this concept with the code below, it pops me a dialog box say "Do you wanna change the value?". I dont want it to pop up a dialog box. Also, i was looking for a message that I tried to give it. Looks like it doesn't even get in the if clause because I have checked. And its because its not null? I dont know. This is the code:
private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e) {
GridView view = sender as GridView;
GridColumn priority = view.Columns["Priority"];
if (view.GetRowCellValue(e.RowHandle, colPriority) == null) {
e.Valid = false;
//Set errors with specific descriptions for the columns
view.SetColumnError(colPriority, "Incorrect Value");
}
}
PS:I have checked that both of these methods get executed, so it isn't like they don't. I used some console.write stuff to check this.
