I have following code block which is working perfectly for OpenOffice SDK to automate Mail merge functionality.
Public Function runQueryOnDataSource(ByVal nameOfdDtaource As String, ByVal query As String) As Boolean
strLog = strLog + vbCrLf + Now.ToString() + ": runQueryOnDataSource nameOfdDtaource:" + nameOfdDtaource + ",query:" + query + "-Started"
Dim oDB As Object, oBase As Object
Dim oStatement As Object
Dim rSQL As String
Dim oRequete As Object
Dim oServiceManager As Object, CreateUnoService As Object
Try
'Creation instance Open office
oServiceManager = CreateObject("com.sun.star.ServiceManager")
CreateUnoService = oServiceManager.createInstance("com.sun.star.sdb.DatabaseContext")
mxMSFactory = (uno.util.Bootstrap.bootstrap()).getServiceManager()
oDB = CreateUnoService.getByName(nameOfdDtaource) 'oDB=XDataSource
'Connection
oBase = oDB.getConnection("", "") 'oBase=XConnection
oStatement = oBase.createStatement 'XStatement
'rSQL = "SELECT * FROM ""26_MailMergeResult_DEMO"
rSQL = query
oRequete = oStatement.execute(rSQL)
Return True
Catch ex As Exception
strLog = strLog + vbCrLf + Now.ToString() + ": Exception" + ex.ToString()
Throw ex
Finally
oDB = Nothing
oBase.Close()
oBase.Dispose()
End Try
strLog = strLog + vbCrLf + Now.ToString() + ": runQueryOnDataSource-Finished"
Return True
End Function
Above code is used to insert data into the DataSource already registered with libre office.But Now when I try to use it, line oServiceManager = CreateObject("com.sun.star.ServiceManager") generates error "Error Creating ActiveX object".
Do anyone have idea, How do I fix this.
This code does not look right, so I'm surprised it ever worked. In other examples, the bootstrap() line always goes first. Then use that service manager instead of a separate oServiceManager variable.
For example, see the Java code at https://www.openoffice.org/udk/common/man/spec/transparentofficecomponents.html.
EDIT:
You're almost there. The getByName() method returns uno.Any, which has a property called Value that DirectCast can use.
Dim oDB As XDataSource
Dim oBase As XConnection = Nothing
Dim xContext As XComponentContext = uno.util.Bootstrap.bootstrap()
Dim xMSFactory As XMultiServiceFactory = DirectCast(
xContext.getServiceManager(), XMultiServiceFactory)
Dim xNameAccess As XNameAccess = DirectCast(
xMSFactory.createInstance("com.sun.star.sdb.DatabaseContext"), XNameAccess)
oDB = DirectCast(xNameAccess.getByName("Bibliography").Value, XDataSource)
oBase = DirectCast(oDB.getConnection("", ""), XConnection)

I am getting this error trying to list objects in a directory on a bucket. I cannot list from the root of the bucket as it has more than 1000 objects, so I need to drill farther down into the directory list to get what I want. My code works when I display from the root of the bucket, but when I try to add directories at the end of the bucket to list their contents I get this error. "Error unmarshalling response back from AWS. HTTP Status Code: 200 OK", "Root element is missing" on the ListObjectsV2. This is a public S3 bucket so I have included my code below so others can try it. I am using AWS-SDK-NET45.zip and compiling as Visual Basic 2019 for .NET 4.8 within an SSIS Script task. This should work, any ideas on what I am doing wrong? Thanks.

Ok I added the prefix option to the ListObjectsV2Request as follows and it worked. I was able to get list of files from just the directory I wanted. I was side-tracked thinking it worked like the GetObjects function where you have to add the directory to the end of the bucketname and list the file you want in the Entry.Key. Hopefully others will find this of help since I did not find much for examples on this.
Dim request As New ListObjectsV2Request() 'With {.BucketName = bucketName}
With request
.BucketName = "/gov-fpac-rma-pubfs-production"
.Prefix = "pub/References/actuarial_data_master/2023/2023_"

I have a code that I was able to string together that logs my sent emails into an excel sheet so i can use that data for other analysis.
In it, I have it resolving the name into an email as outlook shortens it ("Jimenez, Ramon" = email#address.com) as outlook configured this and it works when i send an email to anyone in my company as they are in my address book.
Now, when I email anyone outside it defaults to lastName, firstName so it is not converting this and logging it.
I thought the code I have in here already does this, but I guess not. I have already come this far and I am NOT a software guru at all. Does anyone have insight on how I can also include this as well?? Please see code below:

First of all, there is no need to create a new Application instance in the ResolveDisplayNameToSMTP method:
Set OLApp = CreateObject("Outlook.Application")
Instead, you can use the Application property available in the Outlook VBA editor out of the box.
Second, you need to use the following code to get the SMTP address from the AddressEntry object:
Dim PR_SMTP_ADDRESS As String
Set PR_SMTP_ADDRESS = "http://schemas.microsoft.com/mapi/proptag/0x39FE001E"
ResolveDisplayNameToSMTP = oRecip.AddressEntry.PropertyAccessor.GetProperty(PR_SMTP_ADDRESS)
Instead of the following line:
ResolveDisplayNameToSMTP = oRecip.AddressEntry.Address
Read more about that in the How to get the SMTP Address of the Sender of a Mail Item using Outlook Object Model? article.
I'm trying to implement the newest yahoo weather API in a .NET application (the one we were using was discontinued in favor of this new one): https://developer.yahoo.com/weather/documentation.html#commercial
Their only examples are in PHP and Java. I've done my best to convert the Java example to .NET but I still am getting a "401 - Unauthorized" response. I've gone over my code several times and cannot find any problems so I'm hoping someone else will be able to see where I went wrong. Code is below.

After painstakingly creating a Java app, pasting in the Java example and stepping through it I found that the issue is in a poorly implemented URL Decode function on the receiving end.
In the Java app, URL Encode uses upper case characters while in .NET HTTPUtility.URLEncode uses lower case characters. This is enough to throw off your signature and cause a 401 - Unauthorized error.
My solution was to create a string extension method that will URL Encode in upper case:
<Extension>
Public Function UppercaseURLEncode(ByVal sourceString As String) As String
Dim temp As Char() = HttpUtility.UrlEncode(sourceString).ToCharArray()
For i As Integer = 0 To temp.Length - 2
If temp(i).ToString().Equals("%", StringComparison.OrdinalIgnoreCase) Then
temp(i + 1) = Char.ToUpper(temp(i + 1))
temp(i + 2) = Char.ToUpper(temp(i + 2))
End If
Next
Return New String(temp)
End Function
Using this extension method my signature gets created exactly like the one in the Java app and I am able to retrieve the response.
Hope this helps other .net programmers with this issue!

I open the form and fill it out correctly.
I'll enter something like "4" (no quotes) for JobGrade. It still says "conversion from strink ''" like its not even seeing when I input items on the form.
Errors are below:
System.InvalidCastException: Conversion from string "" to type 'Byte' is not valid. ---> System.FormatException: Input string was not in a correct format. at Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value, NumberFormatInfo NumberFormat) at Microsoft.VisualBasic.CompilerServices.Conversions.ToByte(String Value) --- End of inner exception stack trace --- at Microsoft.VisualBasic.CompilerServices.Conversions.ToByte(String Value) at Profile.btnSave_Click(Object sender, EventArgs e) in
Update
The DBNull.Value issue is resolved.
The JobGrade, and Role are still issues. When throwing up some breakpoints on it doens't fetch the contents of the textbox or the dropdown list.

Edit 2:
So I've pretty much given up on this, and instead moved the table into an FormView ItemTemplate, with an EditTemplate also. I modified it as described in the following link. http://www.beansoftware.com/ASP.NET-Tutorials/FormView-Control.aspx
Q1: Make sure the table structure allows nulls and set the parameter value to DBNull.Value.
Q2:
If IsNumeric(txtJobGrade.Text) Then
sqlCmdUpdate.Parameters("#JobGrade").Value = CInt(txtJobGrade.Text)
Else
sqlCmdUpdate.Parameters("#JobGrade").Value = 0 'Or Default Value
End If
You can always make that a drop down list to prevent open ended data input.
It's a little odd to see how you're done the parameters. Typically, I'd expect to see something more along these lines:
With sqlCmdUpdate.Parameters
.clear()
.addWithValue("#parm1", mytextbox1.text)
.addWithValue("#parm2", mytextbox2.text)
End With
For one, .add has been deprecated -- still works, but some issues to be aware of (http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx).
Secondly, it's always best to call .clear().
Also -- you might think about a more standard approach to checking for values -- for example:
If txtJobGrade.Text <> "" Then...
Would be better written as
If NOT string.isnullorempty(me.txtJobGrade.text) Then...
Try making a few of those changes, and see what (if any) errors you're still getting.
