I'm running into a problem when attempting to see the graphicprovider for a graphic layer to show the results of an IdentifyTask in my program. I'm adding the graphic layer (along with a bunch of other layers) in the initialize code for the page. I tried using the Identify sample from the Resource page (version 1.3) to run a test. When I click on a polygon with the original sample code, the polygon gets shaded with the symbology as expected. However, when I programmatically add in the graphic layer holding the lastIdentifyResultGraphic, the polygon does not get shaded as expected. Where am I going wrong in this code?

pageTitle="Identify Features on the Map" initialize="init();">
<!--
This sample shows how to identify features with a MapClick and the Identify task.
The IdentifyParameters designate which layers are being identified.
Identify operations can potentially return a lot of information
depending on the number of layers being identified and a given tolerance.
The tolerance is the number of pixels a feature is allowed to lie away
from the clicked point in order to be counted as a result.
In this sample, when user clicks the map, an "Identify" task is executed.
When the task finishes executing, the identifyCompleteHandler function loops
through the features in the IdentifyResult and adds them to the map.

You can develop an msi on a machine with a previous version of ArcGIS (say, 9.2) and have it deployed on machine with later service packs or even versions. I have developed several in 9.2 that were used in 9.3. However, you will run into problems when going the other way. The target machine cannot have an previous service pack or version than the development machine. Take a look at this thread to see some discussion on how to check the target machine for the version and service pack, and whether the ArcGIS .NET Assemblies are installed. In my posting in that thread, I was just allowing for deployment on an ArcGIS 9.2 machine. Here are the conditions for a project developed in ArcGIS 9.2, service pack 6 that can be deployed on later machines. The only case where it doesn't work properly is when the machine has ArcGIS 9.2 with no service pack. I couldn't find a way to flag that circumstance while allowing installation on ArcGIS 9.3 with no service pack. Under "Launch Conditions" (Name) - ArcGIS Service Pack Condition - (SP<>"9.2.0.1324")and(SP<>"9.2.1.1332")and(SP<>"9.2.2.1350")and(SP<>"9.2.3.1380")and(SP<>"9.2.4.1420")and(SP<>"9.2.5.1450") InstallURL - Message - This installer is only for ArcGIS 9.2, Service Pack 6 or higher. (Name) - ArcGIS Condition - (VERSION="9.2")or(VERSION="9.3") InstallUrl - Message - This installer only runs for ArcGIS 9.2 or higher.

If you notice in the Form_Initialize code, it's expecting IApplication to be passed to it. Here's the OnCreate and OnClick subroutines. I'm also using a a class that sets ArcMap as the form's parent, as mentioned in this thread.
Private m_application As IApplication
Public Overrides Sub OnCreate(ByVal hook As Object)
If Not hook Is Nothing Then
m_application = CType(hook, IApplication)
'Disable if it is not ArcMap
If TypeOf hook Is IMxApplication Then
MyBase.m_enabled = True
Else
MyBase.m_enabled = False
End If
End If
' TODO: Add other initialization code
End Sub
Public Overrides Sub OnClick()
Dim SelectionForm As New myApp.SelectionForm
Try
If Not SelectionForm.Form_Initialize(m_application) Then Exit Sub
SelectionForm.ShowDialog(New Win32HWNDWrapper(m_application.hWnd))
Catch ex As Exception
MessageBox.Show(ex.Message, "OnClick")
End Try
End Sub

Here's a function I've used in creating featureclasses. I use the IGXDialog.DoModalSave to get the parameters to send to the function, along with the fields that were created. In this code, I'm creating the fields from an existing dataset (pPointFLayer) and also use its spatial reference to create a line featurelayer.

In this example, I have a form with two comboboxes. The first (cboPointLayer) contains the point layers in the view and the second (cboField) contains the fields of the selected layer. The Form_Initialize function populates cboPointLayer and when the user selects a layer, the subroutine cboPointLayer_SelectedIndexChanged populates cboField.
Public Class SelectionForm
Private m_App As ESRI.ArcGIS.Framework.IApplication
Private pMxDoc As ESRI.ArcGIS.ArcMapUI.IMxDocument

cboPointLayer.Items.Clear()
cboField.Items.Clear()

Take a look at this thread for alternate code to determine the type of an object from IGXObject. One problem I ran into when using IGxObject.Category is that the values are localized. For example, I wrote an application that worked perfectly fine on English language machines, but crashed in other languages. In my code, I was checking the type of table that was selected by a user. If I select a dbf file, this code will return a ShapefileWorkspaceFactoryClass.
Select Case pGxObj.Category
Case "Personal Geodatabase Table"
pFact = New ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactoryClass
Case "File Geodatabase Table"
pFact = New ESRI.ArcGIS.DataSourcesGDB.FileGDBWorkspaceFactoryClass
Case "dBASE Table"
pFact = New ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactoryClass
Case "SDC Feature Class"
pFact = New ESRI.ArcGIS.DataSourcesFile.SDCWorkspaceFactoryClass
Case "SDE Table"
pFact = New ESRI.ArcGIS.DataSourcesGDB.SdeWorkspaceFactory
Case Else
System.Windows.Forms.MessageBox.Show("Data type '" & pGxObj.Category & "' has not been coded yet...")
End Select
However, when a user with a German language machine selected a dbf file, he reported getting the error message "Data type 'dBASE-Tabelle' has not been coded yet".

This also happens once in Google Chrome on the first time, but not on refresh. I've been noticing that the tool bar is not consistently appearing in IE7 (we're not able to upgrade to 8 yet). Sometimes, the arrows to move the icons do not appear until I move the cursor over the map (filling in the X,Y coordinates) or resize the window. This is very intermittent.

It's coming up with a different error now. The message Error #1009 flashes briefly, then disappears. The empty error window remains. This happens on Firefox 3.6.6 (upgraded last night) every time I refresh it and once on IE7, but not on subsequent refreshes.

Ken, Thanks for the headsup I was able to get this error in IE 7 when I got home on a slower internet connection...? IE 7 must be do things in a strange order as the offending line of code what just a simple line telling the graphicsLayer to be visible. Hum... Anyway I have put some checks in there now to be sure the graphicsLayer for all my widgets that use graphicsLayers are not null before I try to use them. Hi Robert, I was getting this on Firefox 3.6.3 with Flash 10,1,53,64 and a high speed connection
