I’m trying to create a installation setup for my VB.net application. I
need to insert a custom action while setup is running. So I add a
Checkbox Dialog box to my setup. And I add a dll to the setup
installation to capture Before Install and After Install events. Those
are works fine. But I cannot access my check box value in those
events. If u guys can give me a hint to continue my work really
appreciates.
Following is the Before Install event I have created. I have set some
messages to verify my event works correctly. While I run the setup
those messages are prompt properly.
Private Sub Installer_BeforeInstall(ByVal sender As Object, _
ByVal e As System.Configuration.Install.InstallEventArgs) Handles MyBase.BeforeInstall
Dim koFaxPath As String = Nothing
MsgBox("Installer_BeforeInstall: Starts1")
Dim contextParameters As StringDictionary
Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder
Dim actionDataName As String = String.Empty
Dim arrayActionData() As String
contextParameters = Me.Context.Parameters
For Each actionDataName In Me.Context.Parameters.Keys
arrayActionData = Me.Context.Parameters(actionDataName).ToString.Split("-")
MsgBox(actionDataName.ToString)
MsgBox(arrayActionData(0).ToString)
MsgBox(Me.Context.Parameters.Item(actionDataName.ToString))
Next
Try
Catch ex As Exception
'needs to impliment
End Try
MsgBox("Installer_BeforeInstall: Ends")
End Sub
Thanks in advance.
I have found the answer for that. It may useful for u as well.
Once you have add your dll to the setup project, Go to dll properties.
There is a property called CustomActionData. Fill it as follows
/CheckBoxSequenceGenerator="[CheckBoxName]"
Now you can access this in following code
Context.Parameters("CheckBoxSequenceGenerator")
Please make sure that your check-box property are not assigned to coding.

So, here it goes. To start, A disclaimer, I understand that MS Access is not built for this kind of work. It is my only option at this time.
I have done just a bit of Automation using UIAutomationClient and I have successfully used its other features, however I cannot for the life of me get it to subscribe to events.
Normally, it is supposed to be a bit like this:
Dim CUI as new CUIAutomation
Dim FocusHandler as IUIAutomationFocusChangedEventHandler
Set FocusHandler = new IUIAutomationFocusChangedEventHandler(onFocusChanged)
C.AddFocusChangedEventHandler(Element,TreeScope_Children, null, FocusHandler)
end function
'
'
Function onFocusChanged(src as Object, args as AutomationEventArgs)
''my code here
end function
Yet when I attempt this, I get the error "expected end of statement" on the line:
FocusHandler = new IUIAutomationFocusChangedEventHandler(onFocusChanged)
additionally, if I leave off the (onFocusChanged) I get the error "Invalid use of new Keyword".
It seems like I am missing a reference somewhere. The usual drop down when using "new" does not contain the IUI handler classes though they are in the object library.
I am not sure if there is just some piece I am not accounting for in the code since I am using vba, but all examples seem to be for .net or C#/C++. Any help would be appreciated.
Additionally, I have no problem finding the element in question and all other pieces work fine. If you need any other pieces of the code let me know.
Edit: added set to line 3. No change in the problem though.
After two years this probably isn't relevant any more, but perhaps somebody else encounters this problem... The answer is to create a new class that implements the HandleAutomationEvent method.
Here I created a class named clsInvokeEventHandler and (importantly) set the Instancing property to PublicNotCreatable:
Option Explicit
Implements IUIAutomationEventHandler
Private Sub IUIAutomationEventHandler_HandleAutomationEvent(ByVal sender As UIAutomationClient.IUIAutomationElement, ByVal eventId As Long)
Debug.Print sender.CurrentName
End Sub
And to use it:
Sub StartInvokeHandler()
Dim oUIA As New CUIAutomation8
Dim oRoot As IUIAutomationElement
Dim InvokeHandler As clsInvokeEventHandler
Set InvokeHandler = New clsInvokeEventHandler
Set oRoot = oUIA.GetRootElement
oUIA.AddAutomationEventHandler UIA_Invoke_InvokedEventId, oRoot, TreeScope_Descendants, Nothing, InvokeHandler
End Sub
Currently, I am utilizing ActiveReports to implement a dynamic image via pathname into a report that is generating.
The Images are being automatically generated as .jpg to a server folder. The Active Reports module imports the files using this code.
Sub ActiveReport_ReportStart
Picture1.Image = System.Drawing.Image.FromFile("path\filename.jpg")
End Sub
The problem I am running into is that this report locks out the jpgs from being overwritten.
I am unsure what could be going wrong, but it seems that the report is still using the image files after the report has been generated.
Am I missing a "disconnect" code piece to ensure that an import doesn't allow for continued contact to the file?
I apologize if this is simple, but I can't find anything for this specific instance.
Thank you.
EDIT:
I attempted to get around the lockout by copying them into their own variable. But this didn't work either.
Sub ActiveReport_ReportStart
dim TempImage as Image = Image.FromFile("path\filename")
Picture1.Image = TempImage
End Sub
You can use "Using" block to make sure that the object of the image is disposed as soon as its usage is completed.
Using statement basically marks a boundary for the objects specified in the statement. So when code block using Using – End Using is exited either after normal execution or some exception cause, the framework invokes the Dispose method of these objects automatically.
Here is the suggested code which can be helpful for you in resolving the issue:
Private Sub SectionReport1_ReportStart(sender As Object, e As EventArgs) Handles MyBase.ReportStart
Dim img As Image
Using bmpTemp = New Bitmap("path\filename.jpg")
img = New Bitmap(bmpTemp)
End Using
Picture1.Image = img
End Sub
I was able to get this to work by creating a function that used the Graphics.FromImage method and disposed the original file.
Public Function GetImageFile(ByVal pathfn As String) As Image
Dim tempImg As Image = Image.FromFile(pathfn)
Dim tempBtm As New Bitmap(Width:=img.Width*CorrectFactor, Height:=img.Height*CorrectFactor, Format:=tempImg.PixelFormat)
Using g As Graphics = Graphics.FromImage(bm)
g.DrawImage(tempImg, Point.Empty)
End Using
tempImg.Dispose()
Return tempBtm
End Function
The item that would be placed in the report would be as follows.
Sub ActiveReport_ReportStart
Picture1.Image = GetImageFile("Path\Filename")
End Sub
So this is what I've got -
Public Shared Function GetDirectoryEntry() As DirectoryEntry
Try
Dim entryRoot As New DirectoryEntry("LDAP://RootDSE")
Dim Domain As String = DirectCast(entryRoot.Properties("defaultNamingContext")(0), String)
Dim de As New DirectoryEntry()
de.Path = "LDAP://" & Domain
de.AuthenticationType = AuthenticationTypes.Secure
Return de
Catch
Return Nothing
End Try
End Function
Protected Sub rbAddUser_Click(sender As Object, e As EventArgs) Handles rbAddUser.Click
AddMemberToGroup("LDAP://DOMAIN.local/CN=" & !DISTRIBUTIONNAME! & ",CN=Users,DC=DOMAIN,DC=local", "/CN=" & !SELECTEDUSER! & ",CN=Users,DC=DOMAIN,DC=local")
End Sub
Private Sub AddMemberToGroup(ByVal bindString As String, ByVal newMember As String)
Dim ent As DirectoryEntry = GetDirectoryEntry()
ent.Properties("member").Add(newMember)
ent.CommitChanges()
End Sub
I hope this is easy enough for people to read, anyway the group and user are selected by the users in a table and when they click the add button I want the selected users to be adding to the selected distribution list.
when it gets to the CommitChanges() I get this error
An exception of type 'System.DirectoryServices.DirectoryServicesCOMException' occurred in System.DirectoryServices.dll but was not handled in user code Additional information: An operations error occurred.Error -2147016672
This is a common issue with the Process Model application pool configuration, from the official documentation:
By using the <processModel> element, you can configure many of the security, performance, health, and reliability features of application pools on IIS 7 and later.
This issue exists as CommitChanges() requires elevated privileges, and can be fixed by setting your web-application to run under NetworkManager; this can be done in two ways:
Directly in your code, place the problem code inside this Using statement:
Using HostingEnvironment.Impersonate()
'Problem code goes here.
End Using
Via IIS Manager:
Navigate to your website's application pool;
Navigate to Advanced Settings;
Scroll down to the Process Model group;
Change Identity to NetworkService
I solved the error by passing through my user credentials
Private Sub AddMemberToGroup(ByVal bindString As String, ByVal newMember As String)
Dim ent As New GetDirectoryEntry(bindString)
ent.Properties("member").Add(newMember)
ent.Username = "DOMAIN\USERNAME"
ent.Password = "PASSWORD"
ent.CommitChanges()
End Sub
However my code still doesn't work, I just get no errors.
My goal here is to create a web browser that has a tab system in VB. Since I cannot explicitly name every single new tab the user will use, I have to make more generalized callings. Here's the conflicting code (my btnGo):
Dim thisBrowser As newWebBrowser = Me.tabBrowser.SelectedTab.Tag
If txtAdressSearch.Text.Contains(".com") Or txtAdressSearch.Text.Contains(".net") Or txtAdressSearch.Text.Contains(".gov") Or txtAdressSearch.Text.Contains(".edu") Or txtAdressSearch.Text.Contains(".org") Then 'More to be checked for
thisBrowser.Navigate(txtAdressSearch.Text)
Else
thisBrowser.Navigate("https://www.google.com/search?sourceid=chrome-psyapi2&rlz=1C1ASAA_enUS445&ion=1&espv=2&ie=UTF-8&q=" + txtAdressSearch.Text)
End If
And here's the newWebBrowser code:
Public Class newWebBrowser
Inherits WebBrowser
Private Sub webBrowserComplete() Handles Me.DocumentCompleted
Dim newTab As TabPage = frmBrowser.Tag()
Dim frmSK As New frmBrowser
Dim hi As String
newTab.Text = Me.DocumentTitle
frmSK.txtAdressSearch.Text = Me.Url.ToString
End Sub
End Class
Any time I enter something into txtAdressSearch, Visual Studio raises a NullRefrenceException and highlights thisBrowser.Navigate(txtAdressSearch.Text). As a side note, it says "Object reference not set to an instance of an object."
Anyone know whats the problem here? Thank you.
After debugging for more than an hour, I looked over my code and saw I was missing a big part of it. I wrote it all in and it worked fine. The issue was the tags weren't being defined correctly (and in some cases, not at all) so .Tag was returning Nothing.
Thanks to all who helped.
Hey guys before I was just hiding the parent form, but now when I try to read from the parent file it says it can't because it's already running in a process. I followed some tutorial and it said to go to the project properties and have the application stop running when all the forms are closed.
But now since I did that it says the directory can't be found probably because I am reading the input from the parent form. Anyways here is my code
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" + frmLogin.txtUser.Text))
How should I go about doing this?
Edit:
Private Sub btnHunter_Click(sender As System.Object, e As System.EventArgs) Handles btnHunter.Click
selection = "Hunter"
writeData.classSelection()
End Sub
This is what I have when the button is clicked.
Here is the classSelection sub:
Public Sub classSelection()
If frmClass.selection = "Hunter" Then
writeFile1.WriteLine(frmClass.selection)
End If
If frmClass.selection = "Gatherer" Then
writeFile1.WriteLine(frmClass.selection)
End If
If frmClass.selection = "Farmer" Then
writeFile1.WriteLine(frmClass.selection)
End If
writeFile1.Close()
End Sub
The error points to this line:
If frmClass.selection = "Hunter" Then
Saying part of the file path cannot be found.
If you want to read input textbox in closed parent form, you have to declare public var
Make a new module in your project .. and add this
public sLogin as String
And before you hide or close frmLogin .. add this
sLogin = txtUser.Text
So, you could change your code with
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & sLogin))
matzone has given you a good hint. And to check exactly what your path is, just add a MessageBox using variables :
Dim writePath1 As String
Dim writeFile1 As StreamWriter
writePath1 = "C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & sLogin
If MessageBox.Show(writePath1, "Continue ?", MessageBoxButtons.YesNo) = DialogResult.Yes Then
writeFile1 = New StreamWriter(File.OpenWrite(writePath1))
' ...
writeFile1.Close() ' Very important ! Adrian pointed it out.
End If
^^ and if it works, you can discard the Dialog test or replace it by some test code like If File.Exists(...)
However, I don't understand wether you want to close the parent Form or hide it. It's different !
Closing the parent Form will discard any access to parent Form members, including txtUser.Text.
If you want to close the parent Form, the ChildForm should not be a child of that parent you are trying to close, or you must just hide the parent Form :
frmLogin.Hide() ' Not frmLogin.Close()
If you close frmLogin, frmLogin.txtUser won't be accessible, or use sLogin provided by matzone instead. Alternatively, you should pass frmLogin.txtUser.Text value to a custom property of ChildForm.
Imports System.IO
Public Partial Class ChildForm1
' Inherits System.Windows.Form
' ...
Private _txtUserFile As String
Public WriteOnly Property TxtUserFile() As String
Set(ByVal NewFileName As String)
_txtUserFile = NewFileName
End Set
End Property
Public Sub LoadFile()
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & txtUserFile))
' ...
writeFile1.Close()
End sub
' ...
End Class
Then use this in parent Form :
MyChildForm.TxtUserFile = Me.txtUser.Text
' Me.Close() ' This will definately KILL Form1 (the parent one)
Me.Hide() ' Always use Hide() until you'll terminate your Application
MyChildForm.Show()
MyChildForm.LoadFile()
^^ but this is not a good code either ! Your problem remains unclear (at least for me)
"Still saying it can't find part of the path", then check the path..
Does the file actually exists ?
Does the path contains glitch ? (use the provided MessageBox test)
Does your account can access that directory ? (Windows configuration and account levels)
Well !
In fact, the problem could be somewhere else.
For example, I was able to reproduce your exception by providing an empty string [""] as the value of, either :
frmLogin.txtUser.Text ' = ""
' or
sLogin ' = ""
' or
txtUserFile ' = ""
In fact, I get the "Could not find a part of the path..." exception because the StreamWriter couldn'd read/write to a File, as I didn't provided a valid FileName for that file. As the filename parameter was an empty string "", the provided path for StreamWriter was just representing a directory instead of a file and an exception was raised.
Now, you should check wether you have a valid path before building a new instance of StreamWriter to get sure you are actually pointing to a File ?
Dim writeFile1 As StreamWriter
Dim MyEntirePath As String = "C:\Users\...\Accounts\" + frmLogin.txtUser.Text
MessageBox.Show(MyEntirePath) ' would be enough to be sure your path is correct
' Some test code here...
If everythingOK then ' create the StreamWriter...
writeFile1 = New StreamWriter(MyEntirePath)
' ...
' ...
Also, it's not a good idea to create your streamwriter, and use it in another part/method of your code. You never known if one day, you'll change your code, and forget to make the link between
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" + frmLogin.txtUser.Text))
' plus
Private Sub btnHunter_Click(sender As System.Object, e As System.EventArgs)
...
End Sub
' plus
Public Sub classSelection()
...
writeFile1.Close()
End Sub
^^ too much "here and there"...
You'll obviously also get an exception if you try to click btnHunter twice.. I don't know what is the purpose of your code nor how it works, it looks like a game.. But I would use File.Exist(..) checks, create the file before, if none, and put that in a Try/Catch to check if I eventually don't have administrator rights to write to that directory. Otherwise, make a code that allow user to read/write files to a custom folder. Andalso, you have :
Application.StartupPath
^^ Very usefull, like :
Dim MyFilePath As String = Application.StartupPath + "\Datas\MyText.txt"
After two weeks of coding, I usually forget where I put those "C:\blabla.." or "D:\gnagna\" or what classes actually uses those absolute reference paths. I've dropped this way of getting directories long ago since the day I moved to Win7 on another computer and all such applications I developped using that approach was doomed...
