I belive BinaryData in SQL is nothing but BLOB esri field format. If so, the elements can be stored into BLOB fields using IPersistStream interface. You can look for an article to find a way to store the data using IMemoryBlobStream and IPersistStream interfaces. ... View more

You cant use Me.Close in New() method as the form is not yet created but getting initialised. You can call Me.Close only after displaying form using either Form.Show or Form.ShowDialog. How can I close a Form without ArcMap crashing? Example:        Imports ESRI.ArcGIS.esriSystem Imports ESRI.ArcGIS.Geometry Imports ESRI.ArcGIS.Geodatabase Imports ESRI.ArcGIS.Carto Imports System.IO Imports Microsoft.VisualBasic Imports System Imports System.Windows.Forms Public Class FindAddressForm     Inherits System.Windows.Forms.Form     Public Sub New()         MyBase.New()         InitializeComponent()         ' Populate the street name ComboBox from text file         Dim streetList As String         streetList = "\\csjs186\CPCommon\ArcMap Add-ins\StreetNameList2.txt"         If File.Exists(streetList) Then             Dim r As IO.StreamReader             r = New IO.StreamReader(streetList)             While (r.Peek() > -1)                 ComboBox1.Items.Add(r.ReadLine.Trim)             End While             r.Close()         Else             MsgBox("Can't find " + streetList)             Me.Close()         End If End Sub ...

How I can remove Schema lock?

Hi, Is there a way to change an esricontrol's tooltip?   I tried using the ICommand interface but the tooltip propertry is read-only.    If I have to build a whole new ICommand and/or ITool is there way I can extend a esricontrol so I do not have to build a new control from scratch?   Thank you. David If u r interested to change tooltip property of an In-Built ESRI command/tool then make use of ICommandItem . ... View more

Hi Gray, Thanks for your reply again. Let me try ur approach. But I doubt whether i can embed the default behaviour of the WPF Controls. e.g. If the Control is Listbox and Down key is pressed, will the next item get selected by default or I need to write code for that too. ... View more
