You may use C++ IO manipulaters for same.

for e.g. setw(size) sets the width of the stream you are suppose to output on console.

Hi everybody,

I want to disable a list view item. I know that I should use SetItemState method, but I don't know how.

thank you in advance.

Disabled how? You can set the LVIS_CUT style so icon is grayed, and use custom draw to change the text color to gray.
If you mean disabled as in not selectable, that feature isn't built in to the control.

You are dealing with a security problem. I say this because you are talking about accessing the hardware and I assume that you mean directly. If you want to access the hardware then you need to call a driver to do it for you. On systems like Win2000 and XP you can not access the hardware directly (even in assembly) without it getting upset with you. It does not matter whether or not you are using VC++ or not, it is an OS thing. There is a public domain diver out there some where that will allow you to access hardware ports directly, I used it a couple of years ago and forget its name (so keep looking).

If you post a small example of the problem (in code) or explane what exactly you are trying to do, then someone here will probably be able to help you.

Good Luck,

Using ShellExecute

I have two questions.

1. How do I use ShellExecute inside my MFC program to register an activex control, say MyControl.ocx located at D:\MyFolder?

2. I do not want it to be in the hard disk, but would like to include the activex control within my program as a resource and then I want to register it. I imported it as a resource. How can I proceed?

Regards,
Aljechin Alexander

1) u can use ShellExecute(NULL, NULL, "regsvr32.exe", <path to="" ocx="">, NULL, SW_HIDE);

2) you cant keep an ocx in the resourse and use it if you are doing static linking. if u are doing only dynamic lnking then, one thing you can do is to store the binaries from reourse into the harddisk and register from there.

While you can use ShellExecute() or CreateProcess() for this, you could also use LoadLibrary() and GetProcAddress() to call the exported DllRegisterServer() function.

Halo sir,

I went through your article which demonstrates the usage of UpdateResource(). Nice one. But from that I am unable to understand how do I do the same when I have imported it as a Binary resource into my MFC app. Its like I have an activeX DLL imported as a binary resource and it is a part of my executable now. I need to register the control to any machine on which the executable is run. I have understood that I could do it with ShellExecute() But I do not know how to use this resource!! Is copying this data to a file on the machine and registering it the only possible way? Can I not register it from within my program itself without copying this binary and creating a replica of the actual file?

Thanks for your help.
Aljechin.

Calling GetBuffer and ReleaseBuffer is completely unnecessary. The following will work:

CString FName = "10";
int n = atoi(FName);

It works because CString has an operator LPCTSTR.

Ohh...
GetBuffer and ReleaseBuffer is mostly used where you want to modify data of the CString instead of Format.
