That key handler (provided you've got a message map entry for it) will only trap key downs for the form view. The edit control is a different window.

Your choices here are:

- find a WM_COMMAND from the edit control that does what you want and handle that in the form view
- derive a class from CEdit and reflect messages from the form view into the control. Do a search for MFC message reflection to see how this works.

(This[^] isn't too bad about message reflection but it might be out of date).

Cheers,

i did add the WM_KDOWN but still nbothing happen when i press a key. I tried it with an application Based on CEditView and it works.

It seems a prob with The FormView Class Cry | :((

Isn't CEditView "just" and edit control? Any messages from the edit control will be processed by the CEditView.

An edit control on a form view has an additional window involved. Key down message will be processed by the edit control and not the form view.

Ok, what u said is great and means that my edit control, normally, can implement the OnKeyDow function even if my form is CFormView Class. but based on my code (first message) nothing is happening. Sigh | :sigh:

Re: CEdit And OnKeyDown [modified]

Yep, but your code for the handler is in your CFormView overide, not in a CEdit override.

What I'd do is...

- Derive a class from CEdit
- Add ON_WM_KEYDOWN to its message map
- Implement OnKeyDown

Snip, snip, Bob's yer Aunty.

PS: If you do implement it this way remember to call CEdit::OnKeyDown to allow the normal window procedure to handle the keystroke otherwise you'll cripple the behaviour of the edit control.

It seems the best way, after all spending 4 hours looking for a function or a sample code is stupid Poke tongue | ;-P

I created a CEdit based class, called CTest in whhich i add the OnKeyDown(...) Now how could call it from the OnChangeEdit1 Function of my CFormView? PS: I need to pass the 3 parameters UINT of OnKeyDown << Newbie question sorry

VS2010 - version and copyright and GetAdapters

You don't need to use PreTranslateMessage - that's for doing something global to a message before it's processed by a window.

I used to get the version and copyright from the resource files using the following

char ThisProgramsName[256]="";
GetModuleFileName(AfxGetInstanceHandle(),ThisProgramsName,256);
DWORD dwHandle = 0;
DWORD dwSize = GetFileVersionInfoSize( ThisProgramsName,&dwHandle );
if(dwSize!=0L) {
UINT uVerInfoSize;
char *lpVerInfo = new char[dwSize];
GetFileVersionInfo(ThisProgramsName, dwHandle, dwSize,lpVerInfo );

The libraries have all changed in VS2010. What do I need to link to satisfy these calls, or has the method of retrieving this information changed.

Same question for GetAdapters

This is the old code

PIP_ADAPTER_INFO pAdapterInfo;
PIP_ADAPTER_INFO pAdapter = NULL;
DWORD dwRetVal = 0;
UINT i;
unsigned long LowestHexIP, PossibleIP;
char MacByte[4], MacID[16], LowestMacID[16];

ULONG ulOutBufLen = sizeof(IP_ADAPTER_INFO);
pAdapterInfo = (IP_ADAPTER_INFO *) MALLOC (sizeof(IP_ADAPTER_INFO));
// Make an initial call to GetAdaptersInfo to get
// the necessary size into the ulOutBufLen variable
if (GetAdaptersInfo (pAdapterInfo, &ulOutBufLen) == ERROR_BUFFER_OVERFLOW) {
FREE (pAdapterInfo);
pAdapterInfo = (IP_ADAPTER_INFO *) MALLOC (ulOutBufLen);
}

I'm not sure this is strictly accurate, according to the GetFileVersionInfo[^] page on MSDN you need Version.lib, and I know from my own projects that this has not changed for some time. I expect GetAdapters will have a similar information page that you can look at.

It's time for a new signature.

Do you know where I can download the latest version.lib and IPHlpApi.lib for both win32 and x64?

All these libraries are part of the standard SDK, which (in my case) came automatically with Visual Studio 2010. If you did not get them in this way I guess you need to go to MSDN and search for "Platform SDK".

It's time for a new signature.
