I'm going to take a fast, quick, guess but it looks like you are taking over the dlg procedure and not letting it do default processing. If you hook, you need to call the previous procedure in the chain.

How to do it?

Looking at the MFC source, it appears that your shouldn't be hooking this function if you derive from CFileDialog and that you should get an assert in debug mode. Furthermore, since CFileDialog is hooking this, I fail to see why you need to.

RegOpenKeyEx() return Access Denied (return value = 5)

Exactly, that's my point as well[^].

I want to write the code that notifies me, when new socket is established? Does windows generates any kind of event when new socket is established?

Thanks in advance.

Re: RegOpenKeyEx() return Access Denied (return value = 5) [modified]

Hello,
I am trying to read username from registry of a remote computer.
I am testing the code on two machines. On first machine, I am getting correct output for all remote machines. On second machine, I am getting correct output for some remote machines and error(Access denied)(in RegOpenKeyEx()) for some remote machines.
All the machines are WIN XP SP2 and on same domain. I am really perplexed by this behaviour. Please help.

Below is the code snippet:

lRetVal = RegConnectRegistry(remoteHost, HKEY_LOCAL_MACHINE,&lHKeyhandle); 
    printf("RegConnectRegistry()=%d\n",lRetVal);
    if(lRetVal == ERROR_SUCCESS) 
    {  
        lRetVal = RegOpenKeyEx(lHKeyhandle,TEXT("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon"), 0, KEY_QUERY_VALUE, &lhkey);
        printf("RegOpenKeyEx()=%d\n",lRetVal);
        if(lRetVal == ERROR_SUCCESS) 
        {
            
            DWORD size1 = 1024;
            RegQueryValueEx( lhkey, TEXT("DefaultUserName"), NULL, NULL, 
                       (LPBYTE) DefUserName,&size1);

1. What your account permission level on that system,
whether you are domain or network admin?
2. Which OS you are using?

1) I am using the same limited account on both the machines.
2) Windows XP with SP2.

I suppose it has to do something with some system setting, since, I am using same network userid on both machines - but things working fine on one machine and not on other machine. Please help.

All that proves is that you have permission on somne machines and not others. Can you read that registry key manually (i.e., no code)?

I can read the registry key manually(using both regedit and regedt32).
Is anybody aware of any specific system setting on the machine that will run this application? Confused | :confused:

The firewall (and firewall service) is off.
DCOM configuration is same on both the machines.

Have you debugged it? Where does single stepping break? What does the stack trace look like?

You should learn to use your debugger, it is much more efficient then asking questions on a forum.
Press F5 to start debugging and check where the crash occurs, this could already give you some information. Then put some breakpoints before the crash and debug once again to inspect the values of the different variables...
