I Believe there is No CEdit::ResetText() function exist!, are you using custom EditBox

Sorry it's not a MFC application. It's a .net application so it's System::Windows::Forms::TextBox __gc *.
Does that help or should I be asking this elsewhere??

Hi, I'm trying to prevent a richedit control from processing the WM_KEYDOWN keyboard event whenever the user presses the tab key. The code below does not work for some reason I don't know!! any ideas are appreciated.. thanks
<br />
case WM_NOTIFY:<br />
{<br />
LPNMHDR pNmhdr = (LPNMHDR)lParam;<br />
switch(pNmhdr->code) <br />
{ <br />
case EN_MSGFILTER:<br />
{<br />
MSGFILTER* pMsgFltr = (MSGFILTER *)lParam;<br />
switch(pMsgFltr->msg)<br />
{<br />
case WM_KEYDOWN:<br />
if (pMsgFltr->wParam == VK_TAB)<br />
{<br />
return 1;<br />
}<br />
break;<br />
}<br />
}<br />
break;<br />
} <br />
}<br />
break;<br />

I've got a DialogBar A docked at the top of the frame window.
How can I do to dock another DialogBar B at the right side of DialogBar A.
I tried pFrame->DockControlBar(pDialogBarA, AFX_IDW_DOCKBAR_TOP|AFX_IDW_DOCKBAR_RIGHT) but the AFX_IDW_DOCKBAR_xxx only refer to the frame window

Hi,
Please, forgive me to post to this specific forum. If that is not appropriate, could you point me to some more relevant place?
I'm a complete newbie in using lexx/yacc -like tools in order to build a syntax highlighter add-on to Visual Studio .NET. The thing that is bugging me is that:
each time the lexer recognizes a token, I cannot reliably retrieve the starting position of the matched text in the input string. I'm using something like this that fails for alternate start states in the lexer :
<br />
std::string line;<br />
...<br />
int a_token;<br />
int a_pos = 0;<br />
<br />
while ((a_token = m_lexer.yylex()) != 0) {<br />
<br />
int pos = line.find(m_lexer.YYText(), a_pos);<br />
int end = pos + m_lexer.YYLeng();<br />
<br />
a_pos = end + 1;<br />
The code works almost correctly most of the time (although it doesn't seem right). But it crashes for the input grammar :
<br />
%x single_quotes_string<br />
single_quote ''<br />
%%<br />
' { BEGIN(single_quotes_string); }<br />
<br />
<single_quotes_string>{<br />
[^'\n]*|{single_quote}* <br />
' BEGIN(INITIAL); return TK_STRING; }<br />
\n { BEGIN(INITIAL); return TK_STRING; }<br />
}<br />
%%<br />
<br />

Hi All,
Im creating a dll and I want to put in the code a way to create a registry key. Im only trying to do something very simple - (1) Create a registry key & (2) Have a vaule pointing to the root of c:\
Ive just tried the basic regcreatekeyex method and although it compiles it does not actually create anything and I think ive missed something very fundamental here (please forgive the noobie status). Here is the code:
DWORD dwRes, dwDisposition;
SECURITY_ATTRIBUTES sa;
LONG lRes;
HKEY hkSub = NULL;
lRes = RegCreateKeyEx(HKEY_CURRENT_USER, "mykey", 0, "", 0,
KEY_READ | KEY_WRITE, &sa, &hkSub, &dwDisposition);
It compiles fine but when i run regedit and try to find "mykey" it comes up with nothing. Any help would be greatly appreciated. Thanks
Nic

try:
lRes = RegCreateKeyEx(HKEY_CURRENT_USER, "mykey", 0, NULL, 0,
KEY_READ | KEY_WRITE, NULL, &hkSub, &dwDisposition);
Since you don^t fill the security attributes struct, passing a NULL pointer should do what you want. Same with classname.....

Hi guys
I've got an SDI app and from the view I call a dialog like this.
In CMyView.cpp
void CMyView::OpenMydialog()
{
CMyDialog dlg;
dlg.SetFather(this);
dlg.DoModal();
}
and in my dialog I do this
In MyDialog.h
class CMyView;
CMyView *m_pFather;
void SetFather(CMyView *p_pFather);
and in MyDialog.cpp
#include "myappView.h" (but due to this I have to include first myappDoc.h")
void CMyDialog::SetFather(CMyView *p_pFather) {
m_pFather=p_pFather;
}
What's the usual (and right) way to acces the parent (View) class without to add all these includes?
Now each time I compile , practically all app is compiled again and that's what I want to avoid.
Thanks in forwarding
Doc

void CMyView::OpenMydialog()
{
CMyDialog dlg(this);
dlg.DoModal();
}
//if you wonna get the parent in your dlg class
void CMyDialog::AMethod()
{
//get the parent
CWnd* pWnd = GetParent();
//you can also cast offcourse, but then you^ll need to include the MyView.h in the MyDialog.cpp:
CMyView* pMyView = (CMyView*)GetParent();
}
Hope this helps you,
Greetings,
Davy

The problem is that if I follow your example I don't have access to the view variables.
If I have a member called m_nCalls in my view
How do I access to it?
If I do
CWnd* pWnd = GetParent();
pWnd->m_nCalls
I receive compiling a nice
error C2039: 'm_nCalls' : is not a member of 'CWnd'

If you want to access members of your view class you`ll need to cast....
CMyView *pMyView = (CMyView*)GetParent();
pMyView->m_nCalls = 2;
don^t forget to do an
#include "MyView.h" in your MyDialog.cpp file then..
Greetings,
Davy

Another - more "correct" object oriented method - would be to pass the view's pointer to the dialog's constructor (as another poster pointed out). Then when the dialog needs to communicate with the view it would do so via messaging as opposed to directly accessing the view's members, which is an obvious OOP no-no

You can do the same with C++. See the MSDN article Q178749 for an example.

I am writing a project of ListView . I want to show the Application's Icon in
the Local disk when the ListView initializing.
Although I use the follow way:
CImageList m_img;
SHFILEINFO sfi;
::SHGetFileInfo(_T("C:\Program file\"),//I want to read all the
//Application's ICON under the directory
FILE_ATTRIBUTE_NORMAL,
&sfi,
sizeof(sfi),
SHGFI_DISPLAYNAME | SHGFI_ICON);
m_img.create(32,32,TRUE | COLOR8,1,100);
m_img.Add(sfi.hIcon);
GetListCtrl().SetImageList(&m_img);
but I wonder that why the ListView can not show the Application's icon?
Do you know this is why?
Can you tell me if you me ?
Or Give me a example if you have similar project.
Thank you very much!

Hi.
A piece of software I have been working on relies on the locking and unlocking of 1 byte inside a specified file, from within a thread that is controlled via mutexes.
The problem I am having is intermittent. Occasionally while the following code is called:
TRY
{
m_File.Flush ();
m_File.UnlockRange ( LOCK_BYTE, 1);
}
CATCH (CFileException, e)
{
e->ReportError ();
e->Delete ();
}
END_CATCH
An exception is returned and the exception puts up on the screen "An unknown error occured while accessing an unnamed file" and in the output window "CFile exception: generic, File Unknown, OS error information = 158".
Looking at the values in the CFile object, everything looks fine. Valid handle and valid values in the variables.
Just wondering if anyone has some clue on where to look, what to look for, or even how to fix. Any ideas are welcomed as deadline is fast approaching.
