Need help quickly,, string problem

[Echo773]

can you correct the last line of this section of code???






int Score=1;

BOOL SetWindowText(HWND hWnd,LPCTSTR lpString);

void RemoveRow(int row)

{

int x,y;

int counter=0;



for(x=0; x< MAPWIDTH; x++)

for(y=row; y>0; y--)

Map[x][y]=Map[x][y-1];

Score++;
char nScore[]="";
itoa(Score,nScore,10);
using std::string;
SetWindowText(hWndMain,WINDOWTITLE+ '-' + string nScore);
}

char nScore[]=""; This creates an array with 1 element. Make the array bigger to be able to store the number text representation

[Echo773]

that doesnt seem to be the problem the problem is that i get an error that says "expected primary expression before "nScore" when compiling

[Peter87]

string nScore this is not right

[Echo773]

do you know the proper format?

[Peter87]

It depends on what you are trying to do.

I guess you are trying to concatenate strings here.
WINDOWTITLE+ '-' + string nScore
if WINDOWTITLE is of type std::string it should be enough to write
WINDOWTITLE+ '-' + nScore
If WINDOWTITLE is a c string that will not work because operator+ doesn't work on c strings. What you can do is convert the first string to an std::string and everything will follow.
std::string(WINDOWTITLE) + '-' + nScore
If you don't want to use std::string at all you will have to use std::strcat but that is just more work so I don't show how to do that.

still have a compile error, your right about what im trying to do its just no working, i posted the code to codepad here http://codepad.org/tGnppb3G you can try to compile it, im using bloodshed dev c++

[Peter87]

I don't have windows so I can't compile it but if SetWindowText takes a c string as argument you have to convert it to a c string.
SetWindowText(hWndMain,(std::string(WINDOWTITLE) + '-' + nScore + '-' + string nScore).c_str());

thanks ill try that, let you know if i have a problem later

[Echo773]

eh still no good, i just dont get it, its supposed to be a scoring system based off of the RemoveRow() function

when using
SetWindowText(hWndMain, WINDOWTITLE + '-' + nScore);
i get
1176 invalid operands of types `const char*' and `char[1]' to binary `operator+'

[Peter87]

WINDOWTITLE is a c string. You can't concatenate c strings with operator+

[Echo773]

it works like this
SetWindowText(hWndMain, WINDOWTITLE + '-' //+(string)nScore);
so its a problem with the string function or nScore

[Peter87]

Are you sure that works when you run it because I don't think it does. I realize I made a mistake in the code I posted earlier. Try this instead:
SetWindowText(hWndMain,(std::string(WINDOWTITLE) + '-' + nScore).c_str());

IT WORKS!!! THANK YOU SO MUCH!!!!!!!! OHMYGOD!!!! haha no really thanks
