I figured out the problem, if you look back in my code, i malloc a certain amount, then do a memcpy that is bigger than that amount, causing it to do something bad... 8), easy error for alot work, lol.

should that be something like :
newMsg->data = (char*)malloc( msg.u.reqvid * sizeof(char ) );

Its a typedef struct, im pretty sure this works, cuase it works in other parts of my code.

I think this might be a hack, but im gonna create another GUIQ, with ready to be freed pointers, and when there used in my other thread, they get thrown away in this queue, which the other thread checks, and if there is anything in there, its free's it. Seems like a lot of work to free memory. Wonder why you it must be local heap to be able to free it.

I want a different behaviour for a button when keeping it pressed with the LButton of the mouse.
To repeat the BN_CLICKED using a timer inside the new class is no big deal, it all works fine and dandy.
The thing is that I want to add a new notification code to be repeated while the button is pushed in, something like BN_KEPTDOWN, but I'd like to pick a value that doesn't conflict with some other notification code in a later release of DevStudio and/or MFC (running on VC6 at the moment).
Are there some guidelines regarding creating new notification codes?
I tried MSDN but I was unable to find anything about this.
Links, anyone?

you can use WM_USER then just add to it if you need more than one
|
|

Probably, but WM_USER has nothing to do with notification codes since WM_USER is a message ID.
When you handle the BN_CLICKED event, a WM_COMMAND message is sent from the child to the parent with a 16-bit notification code in the WPARAM parameter of the message. The other 16 bits are the ID of the control and the LPARAM parameter is the window handle of the control.
This is normally taken care of by the framework/MFC.
What I want is a new notification code that is guaranteed not to conflict with other notification codes for buttons.

How about CFtpFileFind::IsReadOnly(), CFtpFileFind::IsDirectory(), CFtpFileFind::IsSystem(), CFtpFileFind::IsHidden(), and CFtpFileFind::IsArchived()?

no.

As best as I can remember, they represent three groups of read/write/execute. Correct? What does the initial 'p' represent?

Here is the situation:
I have a main window, that can have many sub windows/objects. ie ComboBox, push buttons, radio buttons, text boxes etc.. Some of those objects inside that window are hidden and only become unhidden when an event happens, like a button being clicked or a Combobox item is selected.
The window that I am getting is a black box, that is that I dont get the code, and it can change at any given build.
Here is the problem:
I am still fairly new to MFC/Windows API. I have used hooks on other parts of the code, and was just wondering what hook would you use to find out if there was a hidden object that was about to become unhidden as a result of a button click or some other event. If there is no hook, is there another solution that I am not familliar with?
Any help/links on this would be extremely helpfull.
Thanks in advance.

Hi Friends,
I am store some data into vector and mapping it long key for searching (1::1 mapping).Below code
---------------------.h file------------------------
typedef std::vector<item *=""> m_cache;
typedef std::map<long, item="" *=""> m_index;
typedef std::pair<long, item*=""> INDEX_ENTRY;
INDEX_ENTRY IndexEntry(Item * plu);
--------------------.cpp-------------------------
m_cache.push_back(item);
m_index.insert(IndexEntry(item));
-------------------------------------------------
Now the requirment is to retrive the same data with any of 2 different key long1 and long2 from the same vector(1::2 mapping). Can you please help me how to do this?
Thanks

Calling EgWin::Calibrate works only if i do some stuff like Write nothing before i call another void in an unmanaged dll. Why does it not work if i take out this stupid Console::Write("") ??
<code>
class EgWin
{
public:
EgWin() {}
~EgWin() {}
int Init() { return EgInit(&stEgControl);}
void Calibrate(IntPtr hwnd){Console::Write(""); EgCalibrate(hwnd);}
};
public __gc class EgWinProxy
{
public:
EgWinProxy(){}
~EgWinProxy(){}
int _EgInit(){return mpC->Init();}
void _EgCalibrate(IntPtr hwnd){mpC->Calibrate(hwnd);}
private:
EgWin * mpC;
};
</code>

Thanks for your help with Subclassing in Visual Studio 2003.
However I have a new problem.
When creating a Editbox to store initials in, i created the class correctly and linked it to a EditBox. The Subclass was called CInitials and was derived from CEdit. The problem came when I trying to add the WM_CHAR message.
It doesnt show up on the 'Add Event Handler' dialog. The message im trying to filter is OnChar.
Any help will be appreciated.
Thanks

Hi,
Follow this
CInitials::CEdit(derived from CEdit)
make a control variable from CInitials and link it to the editbox(through classwizard)
then you will be able to tap it on the CInitials::OnChar(..)(through classwizard),
or else add the EN_CHANGE handler this will also help you .
Regards

Thanks, but im using Visual C++ 7.1 not Visual Studio 6.0.
Visual C++ 7.1 comes with Visual Studio 2003.
Thanks for the suggestion anyway.

In Visual C++.net 2003 follow these step to get add handller automatically
In Class View,
#1 Right Click on Class
#2 Select Properties
#3 when properties Windows open, click on appropiate Icon of Message or overides to get handller.
Hope this work for you

Hello,
I've been trying to implement an autosave method for an SDI application. There is an article about how to do this here. However, my coding isn't that great, and filling in the missing bits (i.e. where to put the snippets of code) is causing me, and the compiler, problems.
At the moment I'm struggling with the AutosaveTimerChildProc bit. Where does that go?
Can anyone offer some help. A example implementation would be really helpful to me.
Cheers,
Mark

I've already used the GetProcAddress function for half a dozen functions but it seems I've got a problem with that one. Might be a problem with the prototyping but there are few pages about it on the web and it is the first SH* function I try to get the address for.
I tried all the prototypes I could imagine WINAPI, STDAPI, STDAPICALLTYPE with extern "C", dllimport and other __cdecl, __stdcall gave nothing.
So here's the code, any idea welcome:
typedef int (__stdcall *LPFNSHGETICONOVERLAYINDEX)(LPCSTR, int);<br />
HMODULE hMod = ::GetModuleHandle(_T("Shell32.dll"));<br />
if (hMod) {<br />
LPFNSHGETICONOVERLAYINDEX lpfnSHGetIconOverlayIndex;<br />
lpfnSHGetIconOverlayIndex = (LPFNSHGETICONOVERLAYINDEX)GetProcAddress(hMod,_T("SHGetIconOverlayIndex"));<br />
if (lpfnSHGetIconOverlayIndex) {<br />
m_nIndexOverlay = lpfnSHGetIconOverlayIndex("C:\\", IDO_SHGIOI_LINK);<br />
}<br />
}<br />

Try SHGetIconOverlayIndexA or SHGetIconOverlayIndexW

I have found several nice articles on customizing and superclassing CFileDialog to do things like change the dialog size and defaulting to a particular view (list, detail, thumbnail) when displaying files. I haven't found anything on how to change the file display order. I would like to show the files in detail view (done) and then order them by date, descending, in the view. There doesn't appear to be any programatic way to do this, short of creating my own file dialog box from scratch. I have attempted to send messages faking a left click on the date header, but that does nothing.
It would be really nice to show the user the newest files to process. Any ideas?
Thx in advance

**Sigh**
Nevermind. I figured it out. I had to fake up a WM_NOTIFY to the undocumented control that houses the listbox that contains the file names. I had to fake a left click and populate an NM_LISTVIEW structure and pass it into the SHELLDEF_view window message processor. The fake was to tell it the message was from its list control. Send 2 messages to order in descending order.
Whatta zoo.

How to get the same intensity after stretching an image
eg:
Let intensity of a square of 1 unit = 1 x I1
If I stretch the square to 2 units then the intensity = 2 x I2
Both these intensities should be equal
1xI1 = 2xI2 = k(constant)
I am using bilinear interpolation for stretching but the intensities arent equal.
Is there some other method for stretching so that I ll get same intensity in both the images.
Pls Help
