Is there anyway that I can read the file and the items read in are chars instead of strings?
There is, but I don't really think there's a lot of merit in doing so. Using the string functions is safe - it prevents buffer overflows by allocating just the right amount of memory. Trying to allocate memory yourself is just a PITA and can cause all sorts of security errors. I would stick with what you're doing. If it works safely, there's not much point changing it.

I want to paste a icon from resource to a button by using SetIcon(), but neither m_bttnOpen.SetIcon(AfxGetApp()->LoadIcon(IDI_ICON_OPEN));
nor
m_bttnOpen.SetIcon(::LoadIcon(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDI_ICON_OPEN)));
can do this.
Why?
And how to do this by the most simple way?
thankx

Has your button the icon style checked ? (Go in the ressource editor, right click on your button, tab "styles", check "Icon").

I know that ASCII numbers 27 and 28 represent up and down arrows. Is there a way to get these symbols into a CSTring?
thanks
|
|
|
|

CString cUpDown = "\x1B Up and down arrows \x1C";
onwards and upwards...
|
|
|
|

Thanks for your reply, but the resulting string just has dark black lines were I was hoping to see arrows.
|
|

|

That is dependent upon which font you are using to display the text. Look at the CharMap application. Some fonts have corresponding characters for ^ and v, some don't.
onwards and upwards...

Dear everyone,
I create some CEdit box, the height for example is 20.
and the CEdit box is not multi-line.
But the font size is small, for some function, should
set the text content verticle center or bottom in CEdit.
How can i do?
Welcome any suggestion!
Many thks to u!
Best Regards,
Bosicat
Good Luck

Sorry, you can't centre the text in an edit box. It can't be aligned with the bottom either. Top-only, I'm afraid

I got a class declared as follows:
class CWordItemList : public CList<CWordItem*,CWordItem*&>{
public:
void AddTail(CWordItemList* pList);
...
};
void CWordItemList::AddTail(CWordItemList *pList)
{
CList<CWordItem*,CWordItem*&>::AddTail(pList);
//the program asserts(ASSERT_VALID) and throws an error
...
}
How should I derive from CList?

Is it possible to subclass a window belonging to another process?
If yes, then how?
|
|
|
|
|
Yes, but only by using a global hook. There is information on MSDN about how to do this.
Basically you set a global hook (usually a WH_CBT hook) from inside a DLL and when the hook function is called by Windows for a particular process, your DLL is loaded into the address space of that process. You can then subclass whichever windows in that process you want. Usually, you set a hook that activates whenever the HCBT_CREATEWND code is passed (a window is created), but if the window is already created, you may never get the opportunity to subclass it.

Am not sure, but won't using WH_CALLWNDPROC or WH_CALLWNDPROCRET hooks to obtain the handle of the window or its controls after creation then using SetWindowLong() to set the GWL_WNDPROC property could do the job of subclassing the window after its creation?
|
|
|
|
|
WH_CALLWNDPROC hooks are called from the context of the process that calls SendMessage(), not the one that receives the message. As long as a message is sent by the same process as the one you're wanting to subclass the window in, it should be OK.
These will work, but these hook functions are called for every message sent to every window. They substantially slow down the system and are not recommended unless absolutely necessary.

Hello,
Is there any means to update editboxes individually?
For example I have 3 editboxes (one of which is kept blank & readonly when certain condition prevails). When I update data, the focus moves to the readonly (blank) box. Can anybody help me to overcome this?

Use a static text instead of an edit box, unless the user needs to be able to select and copy text out of it. If it has to be an edit box, then call SetFocus() on another window after you update the text box to remove the focus from it.
It the user doesn't need to be able to select and copy text from the edit box, then a static text box is the better option.

How to close Excel from my c-program, if i've opened it with ShellExecute.
HINSTANCE hInstance= ShellExecute(
GetSafeHwnd(),"open","c:/test.xls",NULL,NULL,SW_SHOWNORMAL);
Thx
|
|

You can't close it that way. Use ShellExecute[b]Ex[/b] you get then a handle to your open Excel instance. The other way is to
find excel with "FindWindow" and then send a "WM_CLOSE" or "WM_SYSCOMMAND - SC_CLOSE" message.
