Hi,
The OS's from Win2000 to greater versions will not allow to access the ports directly. you may need to use a third party component to do it. i think in net u can find free libraries.

Have you tried the Win32_ParallelPort WMI class?

- I copy my App with my DLL file to some PC. some of them work ok and some other didn'n work.

I have no clue. What have you discovered using the debugger? Have you narrowed the problem down to just one or two statements? Are you checking return values from functions?

Hi
I want to disable pasting on an edit control
i have created a subclass control for CEdit and am using the following bit of code to disable pasting
which works in the way it stops the user being able to paste into the edit control
but it is disabling the v character as well so they are unable to type that in
Can anyone advise on a solution, so that it disables paste but the user can still use the v char
thanks
Simon
BOOL CCPEditControl::PreTranslateMessage(MSG* pMsg)
{
switch( pMsg->message )
{
case WM_KEYDOWN:
{
switch( pMsg->wParam )
{
case 0x56:
{
if( GetKeyState(VK_CONTROL) )
return true;
}
break;
}
}
break;
case WM_RBUTTONDOWN:
{
return true;
}
break;
}
return CEdit::PreTranslateMessage(pMsg);
}

No, and if there was one you certainly would not find it in the documentation[^]

You just need to override the default processing for the WM_PASTE message, something like:
LRESULT CCPEditControl::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
switch( message )
{
case WM_PASTE:
{
return 0;
}
break;
}
return CEdit::DefWindowProc(message, wParam, lParam);
}

Im currently working on CGridCtrl. I need to support atleast 50,000 rows so i opted for the virtual mode.
The problem raised when I have to add controls into my Grid such as Check boxes and combo boxes. I also want set the
color of the text in virtual mode.
Will you be able to help me out here.
Im very desperate...
Thanks
Rajith

I'm pretty sure the CGridCtrl's virtual mode is very primitive in the fancy things it can or cannot support.
I remember an article I wrote on a progress-bar cell type, and one of my forum questioners asked about using it in a virtual grid. We never really got anywhere.
More recently, CMaunder and co posted another grid control, developed by him and Dundas and now released into the public arena. That may be more useful to you. I didn't find any features that required me to make all the changes in my software to switch over. But improved handling of virtual grids may be a compelling feature for you.

Hello everyone,
I have searched for MSDN for half an hour about a configuration guide for DCOM on the basis of out-of-process server, but failed.
(Suppose I have a working well out-of-process server and I want to use dcomcnfg to make it run on two machines using DCOM)
Could anyone recommend some tutorials?
thanks in advance,
George

Hi Matthew,
VB client does not matter to my question. My question is about how to configure server.
Any recommended tutorials?
regards,
George

No sorry I don't remember ever using any . It was a long time ago but I remember I used the notes I made on a DevelopMentor COM course where I asked a lot of questions. DCOMConfig was part of the course so I guess I was pretty confident with it at the time.
Nothing is exactly what it seems but everything with seems can be unpicked.

Thanks all the same, Matthew!

Hi there,
I am using LogonUser() API in my code to check for the authentication of user credentials. The problem that i am facing is that the API returns true only if the Account User Name is provided and not the Display user Name. For example: If I create a New Account lets say "ABC" with password as "NEWPWD". On passing "ABC" as user name and "NEWPD" as password LogonUser() returns true. If now I change the user name to lets say "XYZ" and call LogonUser() with the changed user name it returns false. How can I resolve this Issue.
|
|

|

So LogonUser("ABC", ...) succeeds and LogonUser("XYZ", ...) fails. Is that correct?
Why would you want to logon using the display name of XYZ rather than the account name of ABC?
