I've developped a sharepoint 2007 feature in vb.net.
Inside, have an application page and in onload method, i want to write message in event log
Dim cs As String = "TESTLOG"
Dim elog As New EventLog()
Dim sourceExist As Boolean
Try
sourceExist = EventLog.SourceExists(cs)
Catch ex As Exception
sourceExist = False
End Try
If Not sourceExist Then
Dim ev As New EventLogPermission(EventLogPermissionAccess.Administer, ".")
ev.PermitOnly()
EventLog.CreateEventSource(cs, "TESTLOG")
End If
elog.Source = cs
elog.EnableRaisingEvents = True
EventLog.WriteEntry(cs, message, EventLogEntryType.[Error])
The source is correctly created but when i try to write, i've an access denied.
I go to registry to set permission full control at everyone but still have the message.
HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Services
Eventlog
Application
How can i write message in event log?
Thanks
I think you need to make sure the user account that is running the website has full access to the event log. See if the following link is of any help.

Background
I have two databases that I need to connect to. One is in Hyperion and the other one is in ESS. I have imported the smartview.bas as stated by the documentation and I am attempting to use the functions within it. I have dummy sheets (SavedLogHyperion and SavedLogESS) for each enviroment to make sure the users logs in before running all the code. I want to retrieve the proper error code if the user closes the window without logging or other things that may prevent the successful login.
Problem
The HypRetrieve only acknowledge for the first result: if the user was able to log to Hyperion environment, but if ESS login window is cancelled or provided with non-valid credentials and then closed, it detects the code as 0 ("Ok"), thus detecting a successful login for the second environment when it was not.
Code
I wrote a function to retrieve the number, I thought that it could be a time thing and that is why I made it (so for the main code could resolve on time), but it seems like it is not.
Function Return_NumCodeSVHypRetrieve(VarTxtSheetToLogin As Variant) As Long
Dim NumCodeHypRetrieve As Long
NumCodeHypRetrieve = HypRetrieve(VarTxtSheetToLogin)
Return_NumCodeSVHypRetrieve = NumCodeHypRetrieve
End Function
This function is called in my main sub
Sub Main()
Dim NumCodeConnectionSheet1 As Long
Dim NumCodeConnectionSheet2 As Long
NumCodeConnectionSheet1 = Return_NumCodeSVHypRetrieve("SavedLogHyperion")
NumCodeConnectionSheet2 = Return_NumCodeSVHypRetrieve("SavedLogESS") 'If I log in "SavedLogHyperion", this variable becomes 0 too, or any other error code that variable had
End Sub
Question
How can I make the correct code according to the sheet attempted to log be correctly saved? I am clueless on what may be the approach
Solution:
The problem seems to be on how the function works; I noticed that when the function is applied, it activates the sheet, which lead me to believe that there was a problem on timing events, I came with the following solution, which has been basically to provide the scenario that I saw the function is expecting to, also I noticed that if I set the NumCode to retrieve as long as the direct result, it does not behave as expected, my approach was to declare it a variant and then cast it to a long instead.
Function Return_NumCodeSVHypRetrieve(VarTxtSheetToLogin As Variant) As Long
Dim VarNumCode As Variant
'It seems the function relies on the sheet being activated and if the Retrives does it, it takes miliseconds to do, which are not sync with excel life cycle, thus causing missreadings
Sheets(VarTxtSheetToLogin).Visible = True: Sheets(VarTxtSheetToLogin).Select: DoEvents
VarNumCode = HypRetrieve(VarTxtSheetToLogin)
Sheets(VarTxtSheetToLogin).Visible = False
Return_NumCodeSVHypRetrieve = CLng(VarNumCode)
End Function
I am automating a website. I am using SeleniumBasic in Excel VBA.
I have a simple Pop-Up, or Alert, with an OK button.
I cannot access the Pop_Up by using Inspect so I have no HTML to show.
When the Pop-Up occurs, I respond with Driver.SwitchToAlert.Accept. It goes away, as desired.
I don't know how to check programmatically if the Pop-Up is present.
If I assume that the Pop-Up may have occurred and use this code on a just-in-case basis, i.e. use the code without the Pop-Up existing, the program stops without any error message.
Is there a way to check if the Pop-Up window exists before I respond?
Well, I found the answer:
I got this code from someone who got it from someone else.
Private Function AlertIsPresent() As Boolean
'Returns true if an alert is present, false otherwise
Dim T As String
On Error Resume Next
T = Driver.Title 'This raises error 26 if an alert(pop-up) is displayed
AlertIsPresent = (26 = Err.Number)
End Function
If function returns 'true', use the Driver.SwitchToAlert.Accept to close it.
I would like to create/use toasters notifications on Excel. Because we already use MsgBox to notify the user that something happen.
But it make the script to stop (pause).
Have you any idea of how to do ?
On google there is "System Tray Notification" but it need a lot of code and this is a old method. Can't find if there is a new method.
For example, the plugin from SAP : "Analysis For Office" put notifications on Excel.
I looked into this once and almost gave up on it entirely until I found a rather 'cheaty' way of alerting users of info without suspending execution, that works on my users machines.
We run Windows 10 here and have SCCM installed for software distribution and updates. I've absolutely no idea if that's mandatory in Windows for updates or not, so I've no idea if this works for you.. but the following code works a treat here if you don't mind the notification resembling a Software Centre notification:
Sub Toastnote(ccmTitle, ccmText)
Shell "c:\windows\ccm\sctoastnotification.exe """ & ccmTitle & """ """ & ccmText & """ "
End Sub
You can call it with:
toastnote "title goes here","message goes here"
It creates a little pop-up that looks like this:
As I say, it's a bit of a cheat and might confuse users who regularly receive CCM notifications, but for my user-base that wasn't an issue.
Lastly, it's probably worth wrapping this in an IF statement that checks the .exe file exists - just a thought..
Using the Plugin "Analysis For Office" from SAP, you can define messages and add them to the standard SAP-AnalysisForOffice message dialog :
Dim lResult As Long
lResult= Application.Run("SAPAddMessage", "This is a new error message!", "ERROR")
The message 'This is a new error message' with severity Error is displayed in the message dialog.
It will do the same as the picture sent with my question.

I had a similar requirement (mainly for debugging)
My solution was to pop up a small form with a single label control and unload it 4 seconds later. The form proeprties are set no not show modal etc.
in a VBA "Module"
Private mFrmToast As frmToast
Public Sub clearToast()
On Error Resume Next
If Not mFrmToast Is Nothing Then
mFrmToast.Hide
Unload mFrmToast
Set mFrmToast = Nothing
End If
End Sub
Public Sub showToast(message As String)
On Error GoTo er_clear_in_4
If mFrmToast Is Nothing Then
Set mFrmToast = New frmToast
End If
mFrmToast.message = message
If Not mFrmToast.Visible Then
Call mFrmToast.Show(False)
End If
er_clear_in_4:
Application.OnTime Now + TimeValue("00:00:04"), "clearToast"
End Sub
The form "code behind" module contained a sample write only property, "message".
Option Explicit
Public Property Let message(ByVal sMessage As String)
lblMessage.Caption = sMessage
End Property
The usage is simply
showToast("your message here")
I have a COM automation server hosted by a VB6 exe.
The COM API is used from Excel VBA:
Dim o as MyCOMAPI.MyCOMType
Set o = new MyCOMAPI.MyCOMType
o.DoSomething
When I create objects in VBA the exe is started along with COM automation and VBA can use the API.
But the exe is closed quickly and "randomly" by Excel, I guess when Excel decides it doesn't need the COM API anymore.
This behaviour is causing random errors.
The simple solution is to start the exe before running the VBA code ; in this case all is working fine as the exe won't stop running until closed by the user.
Have you some information/documentation about the way Excel VBA manages calls to hosted APIs?
Is there a way to avoid this behaviour and have the exe kept open until the VBA code decides to stop it?
This would be the default behavior for a COM automation server when the last object is dereferenced, meaning that the variable that points to the server is set to nothing.
Now, if your code looks something like this today:
Sub MyFunction()
...
Dim o as MyCOMAPI.MyCOMType
Set o = new MyCOMAPI.MyCOMType
o.DoSomething
End Sub
Then, the server life is connected to the life of the o variable. That variable gets set to nothing when the function is finished, and then the server will be shut down (unless there are other variables keeping it alive).
To make sure that your COM server is kept alive for a longer time, simply define the variable as a Public variable as in the sample below.
This sample will start and show Excel and keep it open until the ShutdownExcel function is called.
Public o As Excel.Application
Sub MakeSureExcelIsRunning()
If o Is Nothing Then
Set o = New Excel.Application
o.Visible = True
End If
End Sub
Sub ShutdownExcel()
Set o = Nothing
End Sub
From COM docs.
**Component Automation**
Shutting Down Objects
ActiveX objects must shut down in the following way:
If the object's application is visible, the object should shut down only in response to an explicit user command (for example, clicking Exit on the File menu) or the equivalent command from an ActiveX client.
If the object's application is not visible, the object should shut down only when the last external reference is gone.
If the object's application is visible and is controlled by an ActiveX client, it should become invisible when the user shuts it down (for example, clicking Exit on the File menu). This behavior allows the controller to continue to control the object. The controller should shut down only when the last external reference to the object has disappeared.

When you write an COM server exe the first thing you do it take a reference to yourself when starting as a normal exe else the exe shuts down as soon as initialisation is over.
I need to assign another application as an object and control it.
Typically, I would open a new instance of the application using CreateObject(), but in this instance I need an existing instance of the object that was already opened in Windows Explorer. The object is an Internet Explorer session that, for various reasons, I can't simply navigate to using web browser controls in Office.
Is there a way to grab this application session by its window handle or something so that I can control it using the APIs that VBA offer? It's also essential that the application stays on the page that it was on and that its entire DOM structure remains intact.
Try this in a sub, it works for me
Set objShell = CreateObject("Shell.Application")
IE_count = objShell.Windows.Count
For x = 0 To (IE_count - 1)
On Error Resume Next ' sometimes more web pages are counted than are open
my_url = objShell.Windows(x).Document.Location
my_title = objShell.Windows(x).Document.Title
If my_title Like "The Title You're Looking For" & "*" Then
Set ie = objShell.Windows(x)
Exit For
Else
End If
Next
Now do stuff with this instance of ie
