CEdit problem in displaying CR and LF [modified]

[bhanu_8509]

Dear All, I am using CEdit to display a text in an array like below :

wchar_t szData[5];
szData[0] = 'a';
szData[1] = 'b';
szData[2] = 'c';
szData[3] = '\r';
szData[4] = '\0';
m_EDIT.ReplaceSel(szData);//even I tried with SetWindowTextW

But, when I display the contents, the CR is displaying as boxes, even I tried with '\n' and the result is the same. Since, it is displaying as a box, further text is not displayed on the next line and it is printed in the same line with boxes after every "abc". Please help to solve the issue.

First, there's an error in your code: you are not increasing the index. Is it only a typpo ? Second, you need to have both the carriage return and newline characters (I don't remember in which order, you'll need to test it).

I am really sorry Cedric Moonen. It is a typing mistake in my previous message (now corrected it).

I agree with your comment, when I use \r\n then it is displaying in the nextline but my real problem is that my input text will come like the following :

"abc\rxyz\rpqr\r"

Then you will need to convert it so that all the \r sequences are replaced by \r\n sequences. std::string and CString have functions to do that.

I don't see the purpose behind populating each and every element in a string separately. May be you haven't known of functions like strcpy? This would work for both Unicode and MBCS builds:

TCHAR szData[4];
_tcscpy(szData, _T("abc"));
m_EDIT.SetWindowText(szData);

For entering a new line, use \r\n and make sure that in the properties of the edit box, "multiline" is set to true.

Dear Cedric, Thank you so much now I solved the proble but only one thing is pending. For instance, if the text has more no. of \r in it then how could I replace all the \r. Please give me your advice. I have done already for one occurance of \r and the code is below.

char *str = "abc\rxyz";
stdstr = str;
int idx = stdstr.find('\r');
stdstr.insert((idx+1),1,'\n');
const char* rcData = stdstr.c_str();
int lenA = lstrlenA(rcData);
int lenW;
wchar_t *unircData;
lenW = ::MultiByteToWideChar(CP_ACP,0,rcData,lenA,0,0);
unircData = SysAllocStringLen(0,lenW);
if(lenW >0)
{
::MultiByteToWideChar(CP_ACP,0,rcData,lenA,unircData,lenW);
}
unircData[lenW] = 0;
m_EDIT.ReplaceSel(unircData);
