Hello,
how can I determine if the current build is a Unicode build? Is there any flag defined that tells me that?
For example I have this function:
{
unsigned long uStringLength = string.GetLength();
LPTSTR lp = string.GetBuffer(uStringLength);
DoBinaryWork(lp, uStringLength);
string.ReleaseBuffer();
}But if building a Unicode build this code will not work because Unicode takes 16 bits per character, therefor only the half of the string is passed to the DoBinaryWork function.
How can I check if building Unicode? I assume there is a flag that can be checked with #ifdef, but what is it?

the UNICODE macro is defined if UNICODE is enabled. Alternatively you could overload DoBinaryWork to take a wstring (basic_string<wchar_t>) or a string (basic_string<char>) which may be possible

I'm a little confused by this.
CString::GetLength() returns the length in characters - so it still returns the correct string length, and if the DoBinaryWork() function takes a LPTSTR, then it also should work correctly.
This code should work unchanged under both ANSI and UNICODE builds.

CString::GetLength() returns the length of the string in characters (as you said), but I need it as bytes. A CString character can be 8 or 16 bits long, therefor number of bytes != number of characters.
The DoBinaryWork function takes an unsigned char * as parameter. I forgot to place a cast to the unsigned char * in the code example, sorry.
Any idea how to check for Unicode?

Hi ... can any1 tell me what is wrong with the following code? i'm sure its some silly mistake that i made ... I am trying to create a Richedit control in a window. I have included richedit.h and my code compiles successfully. but _hWnd remains NULL after this call  ... i am using Microsoft VC++ 6 with the Platform SDK 2003 installed. please help me out. thankx in advance.
_hWnd = CreateWindowEx(WS_EX_CLIENTEDGE,
RICHEDIT_CLASS,
TEXT("AA"),
WS_CHILD | WS_VISIBLE | ES_MULTILINE,
10, 10,
100, 100,
_parent,
0,
(HINSTANCE)::GetModuleHandle(0),
0);

After using the following code from MSDN to retrieve the last error right after CreateWindowEx, i get "Invalid Window Handle". 
LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0,
NULL );
MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION );
LocalFree( lpMsgBuf );
-Tareq

|

This seems to suggest that the parent window has not been created yet. Where are you calling the function from?

This code won't work. You'll get an error message saying that you're using an unknown class. You need to change
strcpy(className, "RICHEDIT_CLASS");
to
strcpy(className, RICHEDIT_CLASS);
I tried this and it worked fine.

 thankx a lot man ... i knew it was a silly mistake!!!

Did you init richedit control??
if you use MFC, please try to call AfxInitRichedit() in App::InitInstance().
maybe that's the point.
|
|
|
|
|
No MFC. Just Win32.
-Tareq
|
|
|
|
|
try to use "InitCommonControlsEx();" in your InitInstance() function.
|
|
|
|
|
nope  its the same.
-Tareq
|
|
|
|
|
try
::LoadLibrary("Riched20.dll");
For win95 the rich edit control lib is "Riched32.dll",
for win98 win2k&winxp, the lib is "Riched20.dll"
|
|
|
|
|
tried that also ... i'm sure its some silly mistake. it cant be that complicated.
HINSTANCE hLib;
hLib = LoadLibrary("Riched20.dll");
if (!hLib)
{
hLib = LoadLibrary("Riched32.dll");
if (!hLib)
{
MessageBox(0, "Richedit control failed to initialize!", "Editor", MB_ICONERROR);
exit(0);
}
else
strcpy(_className, "RichEdit");
}
else
{
strcpy(_className, "RICHEDIT_CLASS");

Hi,
I'm looking for an easy way to test my embedded C code.
I have figured out how to get my C code complied into MFC VC6.0, now I would like to take the native C "printf" (for debugging) and display it in a MFC list or text box. I don't care which one
I'm only after debug output and being able to push MFC buttons.
Please help me with a simple way to do this. I'm not an expert C++ programer.

stupid question here?
where would I start to get an editbox receiving strings one line at a time to display the last line. example
1<br />
2<br />
3<br />
4<br />
5<br />
6<br />
7
right now line 6 and 7 are out of view in the editbox, but I want the editbox to show 6 and 7, and hide 1 and 2. In other words just auto display the last messages sent to the editbox.
thanks,
JoeSox

Did you try out CEdit::LineScroll(...)?
from msdn:
void LineScroll(int nLines, int nChars = 0);<br />
<br />
Parameters:<br />
nLines <br />
Specifies the number of lines to scroll vertically. <br />
nChars<br />
<br />
Specifies the number of character positions to scroll horizontally. This value is ignored if the edit control has either the ES_RIGHT or ES_CENTER style.
