You got an error because there is no memory associated with the 'Host' member - it's just a pointer. You must either: 1) allocate memory before the strcpy - for example, l->Host = malloc(...); OR you can change the struct to a specific size for the 'Host' member - for example, char Host[100].
You seem to be confused about the difference between a char* pointer (char *s), and an array of char's (s[100]). You can use either one in the strcpy() function, but if you want to use a pointer, be sure you know where the memory has been allocated.

Vista has lots of restrictions, dealing with registry. You may like to read UAC for that. Search for UAC on MSDN.

I faced the same problem with my application.
I used a manifest.xml in my application as a resource and it solved the problem.
Here are the contents of that manifest.xml file.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="1.0.0.0"
processorArchitecture="X86"
name="CompanyName.ProductName.YourApp"
type="win32"
/>
<description>Your application description here.</description>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="X86"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel
level="highestAvailable"
uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
Call InitCommonControls() in the InitInstance() of ur application
BOOL CURApp::InitInstance()
{
InitCommonControls();
--------------------------
----------------------
}
U can follow these steps to include manifest.xml in ur project.
Once writing manifest.xml is completed, you will want to add the manifest.xml file to your project in the resource editor. In Visual Studio 6, hit Ctrl+R to add a new resource, select all files and double click manifest.xml to add the file. When you see the custom resource dialog, enter the number "24" as the resource type and hit OK. Once imported, right click on the resource to open the properties window and change the ID to the number "1".

Logically.....
You can add that xml file as a resource in a DLL that u are using as a custom action DLL.(No need to call InitCommonControls() in that case.)
By doing that ur DLL will get elevated privileges to read/write registry entries on Vista.

Hi sameer

In Vista there is a concept of User Account Control (UAC) by which it prevents any major changes in registry (though you are logged in as an Admin).
To enable registry changes, we need to provide higher privileges to the application.
To do this there is a tag in manifest.xml …
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel
level="highestAvailable"
uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
Here we are granting the “highestAvailable” privilege to the application/DLL which ultimately grants the permission to ur application/DLL to access (Read/Write) registry.

Hi guys,
I tried with embedding the manifest.xml in my Dll as posted in the previous reply to write registry entry in windows vista. But this fails to create any effect (my Dll could not create the registry entry)

The XML that specifies what execution level you want only makes sense for EXEs, not DLLs, since the execution level applies to a process as a whole.

Hi,
In my poject want to disable and enable ToolBar Button(save,open,new..)
at runtime using view class.
I had used following code but this code not work properly(abnormal termination error are occure)
CToolBar m_wndToolBar;
m_wndToolBar.GetToolBarCtrl().SetState(ID_FILE_NEW,TBSTATE_ENABLED);
m_wndToolBar.GetToolBarCtrl().EnableButton(ID_FILE_NEW,FALSE);
Please help me....

Are you sure, GetToolBarCtrl is returning some valid pointer. Probably, it is returing NULL value.

This statement leads to above guess.

Hi,
Am also try to run the following code, here also abnormal termination error are occured
CToolBar c_oToolBar;
CToolBarCtrl & a_roCtrl = c_oToolBar.GetToolBarCtrl();
a_roCtrl.EnableButton(ID_FILE_OPEN,FALSE);

I am not sure about the approach that u have specified here.
But the following approach will server the purpose of enabling / disabling the tool bar controls.
You need to add a function in your view class.
For example…
Add ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew ) at location shown.
CMyView.cpp
file
=======================================================
BEGIN_MESSAGE_MAP(CMyView, CScrollView)
//{{AFX_MSG_MAP(CMyView)
other message handler functions...
ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew )
other message handler functions...
END_MESSAGE_MAP()
Void
CMyView:: OnUpdateFileNew(CCmdUI* pCmdUI)
{
if( some_Condition)
pCmdUI->Enable(true);
else
pCmdUI->Enable(false);
}
CMyView.h file
Public:
void OnUpdateFileNew (CCmdUI* pCmdUI);
Framework will keep calling OnUpdateFileNew function frequently and will keep the tool bar option enabled or disabled in a way u want.
