 Posted: Thu Jun 12, 2008 7:54 am Post subject: C++ EM_GETLINE problem |
 |
|
| Code: |
int numoflines;
string temp;
TCHAR teststring[128];
numoflines = SendMessage(ScriptWin, EM_GETLINECOUNT, 0, 0);
temp = SendMessage(ScriptWin, EM_GETLINE, 1, (LPARAM)&teststring);
SendMessage(OutputWin, WM_SETTEXT, 0, (LPARAM)(LPCTSTR)teststring); |
Ya...I, trying to put the string into the buffer....and then display it in another window....but sometimes i get random characters after what i put in the first edit box.
Example:
I put "Hello my name is Bob" in the first box.
Then, after this code executes, in the second box it says something like
"Hello my name is BobX*"

| Be sure to null-terminate the string.

TCHAR is just a definition of either char or wchar_t, depending on the character set of the solution.

The return value of the message EM_GETLINE is the number of TCHAR's copied to the buffer.
| Code: | TCHAR tszString[256];
int nLines = SendMessage(ScriptWin, EM_GETLINECOUNT, 0, 0);
int nLength = SendMessage(ScriptWin, EM_GETLINE, 1, (LPARAM)tszString);
tszString[nLength+1] = '\0';
SendMessage(OutputWin, WM_SETTEXT, 0, (LPARAM)tszString); |
Also, don't forget the wParam in EM_GETLINE is a zero-based index of the lines. so 1 is the second line.
