geee. some boolean read only flag, checked in mouse button down handler ignoring the click when set? It's not a pretty elegant, but it works 
|
|
|
|
|
well, I'd something like
<br />
class CView<br />
{<br />
...
CView()<br />
{<br />
...
m_bviewLocked = false;<br />
}<br />
<br />
bool m_bviewLocked;<br />
}<br />
<br />
void CView::OnToolLock()<br />
{<br />
m_bviewLocked = !m_bviewLocked;
}<br />
<br />
WM_LBUTTONDOWN handler = where you handles the mouse click<br />
{<br />
if( m_bviewLocked ) return 0;
}<br />
or some variantion to this

hi..
My code is like that,
CRect Panerc;<br />
<br />
m_wndStatusBar.GetItemRect(m_wndStatusBar.CommandToIndex(ID_INDICATOR_ZEK),&Panerc);<br />
<br />
m_edit.Create(ES_LEFT,Panerc,this,5132);
but not work.
HELPPP!!!

You need to be more specific than "it doesn't work".
From just looking at it, the window styles aren't enough (you need at least WS_VISIBLE|WS_CHILD), and the parent window is wrong (it should be m_wndStatusBar since that's where the edit box should go).

Hello
I want that one button be deactivate(non active) until an other button was clicked on.
How I can do that?
|
|
|
|
|
One solution is messages. Send a message to the control to make it the default control.

can i use EnableWindow for that?
|
|
|
|
|
If you are using only Win32 API:
1) Get the handle (HWND) of the button to disable/enable
2) Use the EnableWindow function to enable or disable the button.
Enable: EnableWindow(hwndButton, TRUE);
Disable: EnableWindow(hwndButton, FALSE);
If you are using MFC:
Make a call to the EnableWindow member function of the CWnd class. This way, the parameter hwndButton isn't needed. The member function of CWnd only has 1 parameter: the BOOL flag to enable or disable.

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

|
|
|
|
you mean in class wizard?
|
|
|
|
|
No, you cannot use the class wizard here. You have to code it yourself.
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

You're referencing a method called Quicksort(std::string,int) that is defined in one of your headers but isn't actually implemented in one of your .cpp files.

today I'm in clinical raven-dead, but I'd check the fact, that:
compiler expects:
Quicksort(std::string,int)
you defines template
T Quicksort(T a[], int n)
couldn't be the array the problem?
What it generates is
std::string Quicksort(std::string a[], int n)
which doesn't actually match the required fn I guess.
But I might be wrong after actualy no-sleeping nigth

Do I need to have Visual Studio .NET in order to use XP Manifests, or Visual Studio 6.0 is enough?
MSDN explains how to use a manifest and tried it with VS 6.0 but it doesn't work. I still get the old theme.

Thank you very much. Downloading that now.
I created a new project (thru WTL AppWizard) with a manifest, compiled it (no changes made to it), and still I don't have an XP style. Am I missing something?

I'm writing a small app in visual c++ 6 using MFC. The app uses an Access database to store user info and such.
In the program users can enter a bunch of data into a listbox. The problem is I don't know how much is going to be entered so I can't just create n fields in the database to hold the info.
I tired making a separate table for the ListBox entires and linking the two but searching the tables gets all messed up in my program now. I can't even use the GetTableName() function to find out what table I'm currently is.
Ideas?

|
|
|
|
What are you trying to do? How could you possible build a database where you don't know how many fields you would have? Are you building a "database maker"?

Would there be any milage in using direct CREATE TABLE SQL, formed dynamically at runtime, prefixing each new table with a unique ID?
