Firstly, as mentioned by others, if you're using C runtime library functions (cout in your case) from a thread you've created then you should be using the multithreaded version (use the /MT option). A second but related issue is how you're starting the other thread. If you're creating a thread from which you're going to use CRT functions then you should use the one of the CRT's thread creation functions: _beginthread, _beginthreadex[^]. If you read the documentation for CreateThread[^] (the thread creation function you're using) it has the following warning:
A thread in an executable that calls the C run-time library (CRT) should use the _beginthreadex and _endthreadex functions for thread management rather than CreateThread and ExitThread; this requires the use of the multi-threaded version of the CRT.
Doing things the way you are results in calling CRT functions on a thread for which per-thread state has not been initialised. As a side note, if you had used _beginthread or _beginthreadex your application would have failed to compile when /MT was not used.

I attempted to bring a Window to the top, but it is only in case the focus is that same application.
Is their a way if I'm browsing chrome, I can bring that Window on top of it.

Try
SetForegroundWindow or ForceForegroundWindow or SetWindowPos or SwitchToThisWindow
or this, but it might not work.
#include <windows.h>
char title[500];
HWND WindowHandle;
BOOL CALLBACK MyEnumProc(HWND hWnd, LPARAM lParam)
{
GetWindowText(hWnd, title, 500);
if(strstr(title, "SomeTitle"))
{
WindowHandle = hWnd;
return FALSE;
}
return TRUE;
}
int main(int argc, char *argv[])
{
EnumWindows(MyEnumProc, 0);
SwitchToThisWindow(WindowHandle,TRUE);
system("PAUSE");
return EXIT_SUCCESS;
}

Hello.
I am confuse. Because of some snippet codes that any work I do can't solve them.(2-dimension arrays. like n[][])
1-a program to get countries and then print the capital of them.
Please give me an example.
2-multiplication of two arrays.(like x[m][n]*y[n][k]).
3- a code to get name and some grades of some students and then print them.(like other it should use dimensional array)
I know it is not accorded to agreement of this site. but I AM CONSTRAINED.
I promise to compensate it.
If you can help me please don't withhold.
THANK A LOT.

Sorry, but I really don't have the time to do your work for you; and if I did it would not help as you would still not understand it. Here is a link[^] to some tutorials and other pages to help you. I am sure that if you need it you will be able to find something similar in your own language.

Why don't you try yourself? The above requirements are quite easy to fulfill, just some basic programming knowledge is needed.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hello,i study the windows via c/c++.but i have some problems about this routine.
//Wiews must always start on a multiple of the allocation granularity
SYSTEM_INFO sinf;
GetSystemInfo(&sinf);
//Open the data file.
HANDLE hFile = CreateFile(TEXT("C:\\HugeFile.Big"), GENERIC_READ, FILE_SHARE_READ\
, NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, NULL);
//Create the file-mapping object.
HANDLE hFileMapping = CreateFileMapping(hFile, NULL, PAGE_READONLY, 0, 0, NULL);
DWORD dwFileSizeHigh;
_int64 qwFileSize = GetFileSize(hFile, &dwFileSizeHigh);
qwFileSize += (((_int64)dwFileSizeHigh) << 32);
//we no longer need access to the file object's handle.
CloseHandle(hFile);
_int64 qwFileOffset = 0, qwNumOfos = 0;
while(qwFileSize > 0)
{
//Determine the number of bytes to be mapped in this view
DWORD dwBytesInBlock = sinf.dwAllocationGranularity;
if(qwFileSize < sinf.dwAllocationGranularity)
dwBytesInBlock = (DWORD)qwFileSize;
PBYTE pbFile = (PBYTE)MapViewOfFile(hFileMapping, FILE_MAP_READ, (DWORD)(qwFileOffset >> 32), (DWORD)(qwFileOffset & 0xFFFFFFFF), dwBytesInBlock);
//Count the number of 0s in the block.
for(DWORD dwByte = 0; dwByte < dwBytesInBlock; dwByte++)
{
if(pbFile[dwByte] == 0)
qwNumOfos++;
}
//Unmap the view; we don't want multiple views in our address space.
UnmapViewOfFile(pbFile);
//Skip to the next set of bytes in the file.
qwFileOffset += dwBytesInBlock;
qwFileSize -= dwBytesInBlock;
}
CloseHandle(hFileMapping);
i can't understand the qwFileSize += (((_int64)dwFileSizeHigh) << 32);
and (DWORD)(qwFileOffset >> 32), (DWORD)(qwFileOffset & 0xFFFFFFFF)
can you tell me something? thank you.

See the description for GetFileSize()[^].
This code is taking the two result values and creating the 64-bit composite value, by shifting the high order bits 32-bits left, casting the result to an _int64 and adding to the low order value.
_int64 qwFileSize = GetFileSize(hFile, &dwFileSizeHigh);
qwFileSize += (((_int64)dwFileSizeHigh) << 32);
This code is extracting the two 32-bit halves of the value and passing them to the MapViewOfFile() function. In both cases the results need to be cast to DWORDs to keep the compiler happy.
PBYTE pbFile = (PBYTE)MapViewOfFile(hFileMapping, FILE_MAP_READ,
(DWORD)(qwFileOffset >> 32),
(DWORD)(qwFileOffset & 0xFFFFFFFF),
dwBytesInBlock);
It's time for a new signature.

Hello all.
I am programming a simple program in win32 console.
#include <stdio.h>
#include <conio.h>
main()
{
int i,j;
char list[80][20];
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
list[i][j]=getchar();
if (list[i][j]=='\n') break;
}
}
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
putchar(list[i][j]);
}
}
}
It should give some char and then print them. but when it want to print some other things (&%^&*vjc) print.

please read the forum guidelines ("how to ask a question"), use PRE tags, ask a specific question and provide symptoms if it does not do as you would like.
Suggestion: If it does not work, start with something simpler; do not enter 20 lines of code if you are not experienced enough to get the first 5 to work as expected.
And do you really want to enter up to 250 characters one by one?

it is not clear what you want.
it is clear this is one of your very first attempts at programming; if it does not work, start with something simpler.
Do not start with 2-dimensional arrays, until you know everything there is to know about one-dimensional ones.

Im only guessing but..
Look at comments in the code.
Once you press enter, it exits the nested for loop and prints out what you put in.
#include <stdio.h>
#include <conio.h>
int main()
{
int i,j;
char list[80][20]={'\r' };
printf("\n input some chars ..\n\n ");
for(j=0;j<1;j++)
{
for(i=0;i<50;i++)
{
list[i][j]=getchar();
printf("%c = %d ",list[i][j],(int)(list[i][j]) );
if ( (int) (list[i][j]==10) )
{
printf("\n User pressed Enter: new line .. ");
break;
}
}
}
printf("\n\nListing..\n");
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
printf("%c",list[i][j]);
}
printf("\n");
}
printf("\n");
return 0;
}
......

When you create your arrays you're not initialising the contents to anything. Have a look at the rules for initialising automatic arrays in C and you might see what's wrong.
Get in the habit of initialising all variables as you declare them, it'll save loads of tears.
Cheers,
Ash

Since you stop collecting inputs at first newline but then ouput the whole array content, some resulting garbage is inevitable, I suppose.

Hello all.
I want to define an array in c win32 console. First column should be name & family of students and other columns should be grades of them.
NOW HELP ME : How can I have this array with first string column and other columns in float.
Thanks in advance.

Create a structure with name and grades as members.
struct _tagStudent
{
char Name[256];
float Math;
float Science;
};Now you can create an array of Students.
struct _tagStudent Student[100];
You can access the members as follows -
Student[0].Name;
Student[0].Math;
Student[25].Name;
Student[25].Science;
