FileView ActiveX Control :: HOWTO: Determine whether a item is a 'special' folder such as the Control Panel, My Network Places, etc

Special folders are folders such as My Computer, Control Panel, My Network Places, My Documents, Windows directory, etc. See the SpecialFolderTypes enumeration for a complete list of special folders.

Use the IsSpecialFolder method of ListItem class to determine whether a listitem is a 'special' item. For example, to determine whether an item is the 'Control Panel' , use the following code :

[VB6]
If fileVw.FirstSelectedItem.IsSpecialFolder(SpecialFolderTypes.Controls) Then
MsgBox ("Selected item is the 'Control Panel' ")
End If

[C++]
//For SpecialFolderTypes.CONTROLS, value = 3
if( m_filevw.GetFirstSelectedItem().IsSpecialFolder(3))
AfxMessageBox(_T("Selected item is the 'Control Panel' "));

FileView.Net Control :: HOWTO: Determine whether a item is a 'special' folder such as the Control Panel, My Network Places, etc

Special folders are folders such as My Computer, Control Panel, My Network Places, My Documents, Windows directory, etc. See the SpecialFolders enumeration for a complete list of special folders.

Use the IsSpecialFolder method of ListItem class to determine whether a listitem is a 'special' item. For example, to determine whether an item is the 'Control Panel' , use the following code :

[C#]

if( fileView.FirstSelectedItem.IsSpecialFolder(LogicNP.FileViewControl.SpecialFolders.CONTROLS))
MessageBox.Show( "Selected node is the 'Control Panel' node");

[VB]

If (fileView.FirstSelectedItem.IsSpecialFolder(LogicNP.FileViewControl.SpecialFolders.CONTROLS)) Then
MessageBox.Show( "Selected item is the 'Control Panel' ")
End If

FolderView.Net Control :: HOWTO: Determine whether a node is a 'special' folder such as the Control Panel, My Network Places, etc

Special folders are folders such as My Computer, Control Panel, My Network Places, My Documents, Windows directory, etc. See the SpecialFolders enumeration for a complete list of special folders.

Use the IsSpecialFolder method of FOVTreeNode class to determine whether a node is a 'special' node. For example, to determine whether a node is the 'Control Panel' node, use the following code :

[C#]

if( fldrView.SelectedNode.IsSpecialFolder(LogicNP.FolderViewControl.SpecialFolders.CONTROLS))
MessageBox.Show( "Selected node is the 'Control Panel' node");

[VB]
If (fldrView.SelectedNode.IsSpecialFolder(LogicNP.FolderViewControl.SpecialFolders.CONTROLS)) Then
MessageBox.Show("Selected node is the 'Control Panel' node")
End If

FolderView ActiveX Control :: HOWTO: Determine whether a node is a 'special' folder such as the Control Panel, My Network Places, etc

Special folders are folders such as My Computer, Control Panel, My Network Places, My Documents, Windows directory, etc. See the SpecialFolderTypes enumeration for a complete list of special folders.

Use the IsSpecialFolder method of TreeNode class to determine whether a node is a 'special' node. For example, to determine whether a node is the 'Control Panel' node, use the following code :

[VB6]
If folderView1.SelectedNode.IsSpecialFolder(SpecialFolderTypes.CONTROLS) Then
MsgBox "Selected node is the 'Control Panel' node
End If

[C++]
//For SpecialFolderTypes.CONTROLS, value = 3
if (m_fldrVw.GetSelectedNode().IsSpecialFolder(3))
AfxMessageBox(_T("Selected node is the 'Control Panel' node"));

FolderView ActiveX Control :: INFO: Making expand/collapse buttons (expandos) fade in and out in Vista look and feel.

Under Vista style, FolderView fades the expand/collapse buttons(expandos) only if the HotTracking property is set to True.

Notes
Vista look and feel is enabled if FolderView is running on Vista and visual styles are enabled for the application.

FolderView.Net Control :: INFO: Making expand/collapse buttons (expandos) fade in and out in Vista look and feel.

EZNamespaceExtensionsMFC :: HOWTO : Use an ActiveX control for a custom view in the namespace extension

To use an ActiveX control for a custom view in your namespace extension, use AfxEnableControlContainer(); in the InitInstance method of namespace extension project. This enables support for containment of OLE controls.

The code is as follows :

BOOL CFileSystemBrowserCustomViewApp::InitInstance()
{
OleInitialize(NULL);
COleObjectFactory::RegisterAll();
AfxEnableControlContainer();
return CWinApp::InitInstance();
}

EZNamespaceExtensionsMFC :: HOWTO: Refresh Windows Explorer when the contents of a namespace extension change

It is often necessary to refresh the Windows Explorer tree(left window) and list(right window) in response to changes in the contents of the namespace extension such as when the user logs on or off. Use the following code for that :

CNSEFolder* rootFolder = this->GetRootFolder();
rootFolder->RefreshView();
rootFolder->NotifyUpdated();
rootFolder->InternalRelease();

EZNamespaceExtensions.Net :: HOWTO: Refresh Windows Explorer when the contents of a namespace extension change

It is often necessary to refresh the Windows Explorer tree(left window) and list(right window) in response to changes in the contents of the namespace extension such as when the user logs on or off. Use the following code for that :

[C#]
this.RootFolder.RefreshView();
this.RootFolder.NotifyUpdated();

[VB.Net]
Me.RootFolder.RefreshView()
Me.RootFolder.NotifyUpdated()

FolderView ActiveX Control :: HOWTO: Use ByRef event parameters in VBScript in an HTML/ASP page

VBScript does not support ByRef parameters, so those events which use ByRef parameters to pass back information to FolderView do not work. Thus, the following VBScript code to do custom sorting does not work :

<SCRIPT language="VBScript">

Sub FolderView1_OnOleStartDrag(Data,Node,effects,button,Cancel)
' 1 = DROPEFFECT_COPY (Only Copy operation allowed)
effects = 1
end sub

</SCRIPT>

Instead of using the ByRef parameter, the information should be passed to FolderView using the SelectNode method as follows :

<SCRIPT language="VBScript">

Sub FolderView1_OnOleStartDrag(Data,Node,effects,button,Cancel)
' 1 = DROPEFFECT_COPY (Only Copy operation allowed)
value = "intprop:" +cstr(1)
folderView1.SelectNode(value,0,0)
end sub

</SCRIPT>

Use the prefix "intprop:" for ByRef parameters of type 'integer' or 'long'; use "strprop:" for ByRef parameters of type 'string' (used in OnInitialize and OnGetInfoTip). Note that the prefix ("intprop:" or "strprop:") must be lowercase.

FileView ActiveX Control :: HOWTO: Use ByRef event parameters in VBScript in an HTML/ASP page

VBScript does not support ByRef parameters, so those events which use ByRef parameters to pass back information to FileView do not work. Thus, the following VBScript code to do custom sorting does not work :

<SCRIPT LANGUAGE="VBScript">

Sub FileView1_OnCompareItems(Item1, item2, comparison)
' Sort items in ascending order of length of display name
c = len(item1.displayname) - len(item2.displayname)
comparison = c
end sub

Sub FileView1_OnBeforeColumnSort(columnName, columnIndex, sortType)
c = 3 ' custom sorting
sortType= c
end sub

</SCRIPT>

Instead of using the ByRef parameter, the information should be passed to FileView using the CurrentFolder property as follows :

<SCRIPT LANGUAGE="VBScript">

Sub FileView1_OnCompareItems(Item1, item2, comparison)
' Sort items in ascending order of length of display name
c = len(item1.displayname) - len(item2.displayname)

fileview1.CurrentFolder = "intprop:" + cstr(c)
end sub

Sub FileView1_OnBeforeColumnSort(columnName, columnIndex, sortType)
c = 3 ' custom sorting
fileview1.CurrentFolder = "intprop:" + cstr(c)
end sub

</SCRIPT>

Use the prefix "intprop:" for ByRef parameters of type 'integer' or 'long'; use "strprop:" for ByRef parameters of type 'string' (used in OnInitialize and OnGetInfoTip). Note that the prefix ("intprop:" or "strprop:") must be lowercase.

Shell MegaPack ActiveX :: HOWTO: Enable Vista look and feel when running on Vista

v2008 of FolderView, FileView and ShComboBox support the Vista look and feel when running on Vista. To enable this feature, the host application must be using visual styles. This can be enabled by using an application manifest.

Note : In case of FolderView, to enable the full Vista effects such as fading (+) and (-) buttons, the HotTracking property must be set to True.

Shell MegaPack.Net :: HOWTO: Enable Vista look and feel when running on Vista

v2008 of FolderView, FileView and ShComboBox support the Vista look and feel when running on Vista. To enable this feature, the host application must be using visual styles. This can be enabled by using an application manifest or calling Application.EnableVisualStyles method (this method is added by default by the project wizard in Visual Studio 2005 and 2008)

Note : In case of FolderView, to enable the full Vista effects such as fading (+) and (-) buttons, the HotTracking property must be set to True.

EZShellExtensions.Net :: HOWTO: Enable Windows XP Visual Styles for a property sheet extension

To enable Windows XP Visual Styles (themes) for a property sheet extension, call the Application.EnableVisualStyles method at the very beginning of the constructor of the PropertySheetExtension derived class as follows :

[C#]

// AssemblyInfo is a PropertySheetExtension derived class
public AssemblyInfo()
{
Application.EnableVisualStyles();
InitializeComponent();
}

[VB.Net]

' AssemblyInfo is a PropertySheetExtension derived class
Public Sub New()
MyBase.New()

Application.EnableVisualStyles()
InitializeComponent()

End Sub

Notes
Set the BackColor property of the PropertySheetExtension to Transparent to make sure that the child controls such as labels are drawn correctly when using XP visual styles.
