Are you sure that the HAL will allow you to do this? What is it that you are trying to accomplish? Have you looked into _inp() and _outp()? There's also the WinIO library.

Hi:
Thank you for your help! In my program i need to read/write data from/to a digital I/O, so i need this function.
|

Under Windows NT/2000/XP/2003, user applications are not allowed to access I/O ports directly. I/O ports are allowed to be accessed only by device drivers.
If you have purchased a piece of hardware that you wish to control, then you need to contact the manufacturer for a driver and interface software for it.
If you are building custom hardware, then you will need to write a device driver using the Windows Driver Kit[^] or WDK, formerly called the DDK.

you should use driver and call its functions .

Hi ,
I want to write a VPN client in C++. I am wondering if someone can tell me what is involved in this or maybe point me at some whitepaper on how to do this. I know that VPN servers work on several protocals ie. L2PP, IPSEC, PPP etc. but I am not sure how to connect to a server using these protocal or what is required in terms of sending and recieving.(ie, handshaking) in VC++.
I have looked at the web and couldn't really find an open source Windows VPN program to study.
Thanks in Advance

Dear Sir;
I am using Visual c++ 6.0 with sql server 2000 as database.
I have one view on wich there are 3 buttons : Update button, clear and search button.
One time, when I search some thing, i can change other fields of my screen and I click on Update button to update my database . But there is some thing strange.
even if I update my database, when I search for second time the same record, I don't see those modifications but when I open manually the database I see that the record is changed. Then where comes that from the program it show me the first record(without changes) ?.
What to do?

Hi,
Hi i designed a seperate soft keyboard in my application with the same layout of system keyboard using Bitmap.If i press F1 in that soft keyboard it will gives same functionality of system F1.So, to mapping this keys,i use WM_SYSKEYDOWN..etc..
My problem is ...In my soft keyboard..alphapet and number keys are not working.I will gie the code here
CView *curView = (CView*)fChWnd->GetActiveView ();
switch (keyvalue)
{
case 56 :
curView->PostMessage(WM_KEYDOWN,54,0);
break;
case 57 :
if (curView)
curView->PostMessage(WM_KEYDOWN,55,0);
break;
case 58 :
if (curView)
curView->PostMessage(WM_KEYDOWN,56,0); break;
This is my code snippet..where keyvalue is number of total keys in my soft keyboard.
I think iam using correct command..But when i entering 1,2,3..in my soft keyboard,it won't enter in my dialog.
Please help me..
Iam getting the active window by using GetActiveView() function.

what the curView actullay. Hope its CEditView. right?
Go to the View class and overide the WM_CHAR , WM_KEYDOWN messages And chek if any of the message u send arrives here.

CMDIFrameWnd *fWnd = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *fChWnd = (CMDIChildWnd*)fWnd->GetActiveFrame ();
CView *curView = (CView*)fChWnd->GetActiveView ();
I am getting currently active window in curView.In my appliction,i have to enter value int to dialog edit box by pressing numbers in soft keyboards(that i made in application)
Anu

that's wasn't my question...
If the currently active view is not a type of CEditView, there will not be any effect sending the WM_CHAR messages. If the view if of type CVew or CFormView etc nothing happens, when u send a message or even dirctly press a key from the actuall keyboard . So first make sure the active view is of type CEditView.

Have you tried using WM_CHAR, instead of WM_KEYDOWN? The keycodes will be different, however. Or you could use SendInput, but I think you'd have to send a WM_KEYDOWN, WM_KEYUP combo.

Hello everyone,
I am learning developing C/C++ applications for Windows Mobile platform. I often met with the two confusing item, Windows Mobile 5.0 and Windows Mobile 2005. Are they the same thing -- means the next version of Windows Mobile 2003?
thanks in advance,
George

Everyone predicted that the version of Windows Mobile after 2003 SE would be called 2005, but Microsoft decided when announcing it that it would be called 5.0. You will sometimes find resources referring to the predicted name that either haven't been updated, or were written by people who didn't keep track of Microsoft's marketing.

Thank you Mike!
Do you know whether Micorosoft provides some documents to clarify this issue?

what are you calling .NET ?
the development environment (Visual Studio .NET 2003) or the .NET framework ?
i mean, is you dll a managed code library, or native ?
