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.

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)

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.

Does anyone know how to open a Netscape or Mozilla Firefox certificate store with CertOpenStore from Wincrypt.h?
I have access to the .db files from Netscape or Mozilla Firefox but am not sure how to get access to them from my C++ application.
Thanks,

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?

hi everyone,
Sorry if my question sounds too foolish.
I am totally new to .NET, I have .NET code which call a DLL function. I want to debug the dll function. but the devenv does not step into dll function.Is there any setting in .NET env to do this? or any other way of doing this.
Regards
Abhi Lahare

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 ?
|
|
|
|
|
hi Toxcct,
The DLL is a C++ DLL, and .NET is a C# application.
since i am not aware of managed code library, or native i cannot answer that.
Thanks in advance

wow, i think you have some lacks i have to fill here.
C++ is only a language. you can program for different target system with C++, like Windows, Unix, Mac... the difference (if you code is well written and portable) will not be in your sources, but in the binary the compiler/linker generates. this binary is commonly called "native", as it directly contain the microprocessor instructions.
by opposition to native code, .NET (i mean, the .NET framework) is a framework like the Java Virtual Machine which - is supposed to - allow the code compiled to work on every plateform. this implies the compiler generate an intermediate language (MSIL for .NET, ByteCode for JavaVM). this intermediate language is called Managed code because its execution is done only within the .NET framework.
some languages (like C#) generate only managed code. but C++ can do both.
if you program with Win32/MFC/ATL/WTL libraries, then the code will generate some native instructions. but the Microsoft C++ compiler can also generate "Managed C++" also called (C++/CLI) for the .NET framework.
then, to come back to your problem, when you say the DLL is a C++ DLL, you don't explain much.
also, saying that .NET is a C# application does no only explain nothing, but is wrong in the facts.
now, knowing these things, can you please explain what problem you encounter, and what you want to do ?

hi Toxctt,
Or do i have to set the debug path and trace through the dll function? but i don't want to do that.
Thanks in advance,
Abhi Lahare
