Hi,
im trying to create a key along with value under registry as follows....
LPCTSTR data=_T("HKEY_CURRENT_USER\\Software\\Siemens\\Tester\\Test");
CRegKey::SetKeyValue(data,_T("sample"),_T("SampleTest"));
The above gives error like....
error C2352: 'ATL::CRegKey::SetKeyValue' : illegal call of non-static member function...
pls help me out...

Of course your code is like this
CRegKey p;
p.SetKeyValue(data,_T("sample"),_T("SampleTest"));?right

I suppose he has to open the key before writing to it.

Well, the message is clear: you need an object, instance of the CRegKey class, and call its SetKeyValue method.

Thanks for ur reply...
Ya tried what u have suggested the issue i need to create Tester\\Test key under HKEY_CURRENT_USER\\Software\\Siemens and SampleTest(key value) under Test key...and when i tried the above function im getting Abort Message Box...i think this function creates value only under existing keys....
Please correct me if im wrong...

CRegKey's Create method looks promising...

Hai!
When we develop an application in visual C++, we can verify the code by debugging, by keeping break points etc..
Now i am developing an application in embedded VC++ for a WIN CE 5.0 OS Pocket PC Device. My application uses WINSCARD library for supporting PCSC functions, why i mentioned above library is that now i cannot use Pocket PC 2003 emulator. In order to check my application i am always building the .exe , taking the .exe to the pockect PC device and running it, Now even if there is a logical mistake it takes huge time to find it .
Because i am not able to debug my code.
So is there any way so that i can debug the code in my XP operating system itself, keep break points, check the code flow etc. what i need is the application must run on the WINCE device connected to my system, but it must virtually run in my XP system ( NOTE: I cannot use emulator)
Thanks!

Yes it is possible: you need to have your PocketPC connected to your desktop. Then when you can simply press F5. The debugger will try to connect your PocketPC and copy the file on the PocketPC.
The big problem is that it is extremly slow, that's the reason why it is always easier to debug through the emulator.
|
|
|
|
|
Yes,
When I am pressing F5 the code is building and a status bar is comming stating "connecting to device" and then after some time i get an error message that "Timed out".
How to solve above problem ?
Assuming the device has been connected, Even if it is slow no problem, Can i debug the code from my desktop PC, can i keep break points.. etc.
Thanks!

Do you have ActiveSync installed ? It's been a long time I didn't do that but if I remember correctly, everything was working fine for me.
Which version of Visual Studio are you using ?
|
|
|
|
|
I am developing my application in eMbedded Visual C++ 4.0 and installed MICROSOFT ACTIVESYNC 4.5.
By the way my WIN CE device has a COM port wire and a USB wire which one shall i have to connect to my Desktop PC
I tried by connecting both of them , and then i got the "Timed out error message!!
Thanks!

Hi,
I have created MFC application.I am having 2 Dialog boxes.If I click "Add" button(push button) on first Dialog second dialog will open.After canceling of second dialog once again focus is coming on Add Button.At that time I need to refresh my list box,which is on first dialog.
I need to get focus of Add button.So I have created small program like this
BEGIN_MESSAGE_MAP(CMyThreadDlg, CDialog)
ON_BN_SETFOCUS(IDC_BUTTON2, &CMyThreadDlg::OnBnSetfocusButton2)
END_MESSAGE_MAP()
void CMyThreadDlg::OnBnSetfocusButton2()
{
MessageBox(_T("Focus"));
}
If I click on that button focus is coming but function is not calling.Can anyone help me.

Why do you need to refresh your listbox when your add button gets focus? I am just guessing but i believe what you want is to refresh your list when your second dialog is closed. If it is a modal dialog then all you need to do is refresh your list after your second dialog's DoModal returns.
void CMyThreadDlg::OnPressedAddButton()
{
CMySecondDialog Dlg(this);
Dlg.DoModal();
RefreshMyListNow();
}
If you insist on the focus change maybe try using ON_BN_SETFOCUS(IDC_BUTTON2, OnBnSetfocusButton2) instead of ON_BN_SETFOCUS(IDC_BUTTON2, &CMyThreadDlg::OnBnSetfocusButton2), does that help?

Thanks for your reply.I am calling refresh function after second dialog returns.
My code is working fine.

Hi,
i have a function which takes a parameter as LPCTSTR ie...
f1(LPCTSTR str)
{
ShellExecute(NULL, "open",str,NULL,NULL, SW_SHOWNORMAL)
}
The above function gives error like...
error C2664: 'ShellExecuteW' : cannot convert parameter 2 from 'const char [5]' to 'LPCWSTR'
pls help me out..
|

Use
ShellExecute(NULL, _T("open"),str,NULL,NULL, SW_SHOWNORMAL)<br /> instead. I suggest you take a look at this article[^] to get a better understanding about strings manipulation and UNICODE (this explains why you have the error).
|
|
|
|

the given answer is correct.
But for the future you really need to understand the difference between these string types. LPCTSTR is a macro which resolves in ANSI in 1-byte chars BUT in UNICODE in 2-byte chars. At best you take a look at the byte layout in debugger. 
If you dont consider this in your work you will have a lot of annoying bugs. 
Press F1 for help or google it.

That's why I gave a link to an excellent article explaining all these things in detail

For future reference, the error you are receiving has nothing to do with f1() or its LPCTSTR parameter. The error has to do with the string literal being passed to ShellExecute().

Hi all
I have a simple change password utility that I wrote in Visual c++. It happily runs on Windows 2000, XP, and Windows 2003 sp1. Recently we upgraded to Windows 2003 sp2 and the program no longer works on that platform. It still works through XP sp2, Wind 2000 etc.
What happens is that a user will enter their username, domain name, old password and new password and this will change the password for that user. It always worked before but since Win2k3 sp2 it now retuens the error NERR_PasswordTooShort, indicating that the password does not meet complexity rules of the domain. Nothing was changed in relation to complexity rules. I had a server that was not upgraded to Win2k SP2 (still on SP1) and it worked a treat. The code snippet I use is below. Has anyone seen this issue?
Thanks fro any assistance
---------------------------code snippet-------------
nas = NetUserChangePassword(
wComputerName,
wUserName,
wOldPassword,
wNewPassword
);
if(nas != NERR_Success) {
switch ( nas ) {
case ERROR_ACCESS_DENIED:
AfxMessageBox("The user does not have access to the requested information.");
break;
case ERROR_INVALID_PASSWORD:
AfxMessageBox("The user has entered an invalid password in Old Password.");
break;
case NERR_InvalidComputer:
AfxMessageBox("The Computer name \\ Domain name is invalid.");
break;
case NERR_NotPrimary:
AfxMessageBox("The operation is allowed only on the primary domain controller of the domain.");
break;
case NERR_UserNotFound:
AfxMessageBox("The user name could not be found.");
break;
case NERR_PasswordTooShort :
AfxMessageBox("The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements.");
break;
default:
AfxMessageBox("Password Change Not Successful");
}

I'm new in VC++ 2008.
i got a CAD file which is already convert into STL file.
how do i display it as a 3D image in MFC..
Wat knowledge should i must have to handle this task?
|

Using pure GDI, this will be very complex because GDI only draws 2D (so you'll need to make all the conversions from 3D to 2D yourself, which is probably not what you want). What you could do, is use OpenGL inside your MFC application to take care of the 3d drawing (or another graphic library like directX, but I think OpenGL is more suited to this task).
This is a rather complex task and it is impossible to answer in a single post, so my reply is a general guidelins so that you know a bit where to look. For a start, I would search for articles on CP that describes how to embedd OpenGL in an MFC application (I saw at least one such article) and then I would start to learn OpenGL. This[^] is an excellent book to learn everything you need. You can also find a free version of the book for previous version of OpenGL on the net (which are legal).
On the other hand, somebody perhaps wrote such a control to display an STL file, but I guess you already search for that on google and couldn't find anything. Apparently you didn't because after a very quick search, I found this[^]. You could go and take a look at the implementation. Maybe there are other articles on the subject also.
