Look at the ZwExtendSection native API

Is it Possible to make in one time all controls on a form in blank ?
I am using Visual C++ 6.0 MFC
I am learning my self
|
|
|
|
|
the only way to do this is to use UpdateData() when no values where stored into the controls' copy

there is not "automatic" way of making all controls "blank", you need to go one-by-one.

i don't agree, using UpdateData() allow users to do such behavior, unless you used this function to transfer datas between your dialog and your associated class...
however i don't agree with the totality of this[^] article, the author talks about that special point...

but you still need to set all values to something before using UpdateData.

As toxcct alludes to, you can use DDX and then initialize each variable before calling UpdateData() or if you're not using DDX you could write a loop that would loop through all the controls on the dialog and then using the SetWindowText message, blank all controls.

yeah man, first of all, if you want a quick answer that satisfy you, begin with express yourself clearly.
well, now, don't you use a default constructor of your date object that fills it with 1/1/1900 ?

No,these date fields are empty when i introduce data on the records.
when a look on the SQl server 2000 database I see this. This problem is not Visual c++ but SQl server.

I'm trying to use resetText () to reset values of some text boxes to their default. I'm using it as follows,
<br />
myTextbox->ResetText ();<br />
but all this seems to be doing is clearing the text instead of resetting defaults.
Any ideas???? Because I'm stuck.

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.....
Greetings,
Davy
