VBA - grabbing column names from lotus notes database using getColumnNames method - vba

So I have a view (object name is 'view') in a Lotus Domino db from which I want to grab the column names and put them in an array:
Dim view As Domino.NotesView
Set view = db.GetView(viewScen)
//viewScen is a string containing the actual view's name
//db is a string containing the actual db name
These declarations work fine, but when I try to assign those values to an array using the method called 'getColumnNames', the VBA editor tells me that the method is not supported for that object:
Dim someArray() As String
//I tried both of the following with no sucess...
someArray = view.getColumnNames
someArray() = view.getColumnNames
What am I doing wrong?

I think you can do a For..Each with columns
dim idx as integer
dim OneCol as Column
redim someArray(view.Columns.Count)
For idx = 0 to view.Columns.Count - 1
someArray(idx) = view.Columns(idx).name
Next

According to the 8.0 help files, the getColumnNames method is not supported in COM/OLE. However, the attribute ColumnNames is supported. This is VB code from the Help file:
Private Sub ViewColumnNames_Click()
Dim s As New NotesSession
s.Initialize
Dim dir As NotesDbDirectory
Dim db As NotesDatabase
Dim v As NotesView
Dim cns As String
Set dir = s.GetDbDirectory("")
Set db = dir.OpenDatabase("Web test")
Set v = db.GetView("Main View")
For Each cn In v.ColumnNames
cns = cns + cn + Chr(10)
Next
MsgBox cns, , "Columns in Main View"
End Sub

How to SET category/series name in PowerPoint charts?

I'm writing a macro to set categories/series names. New labels are taken from some dictionaries. My first step however was to get those names from each chart. So, in order to get it, I used the code below:
'works fine
'x - any integer
'whole sentence
Application.ActivePresentation.Slides(x).Shapes(x).Chart.ChartGroups(x).CategoryCollection(x).Name
'with variables
Dim objChart As Chart
Dim objChartGroups As ChartGroups
Dim objChartGroup As ChartGroup
Dim objCategoriesColl As CategoryCollection
Dim objCategory As ChartCategory
Dim strCategory As String
Set objChart = ActivePresentation.Slides(x).Shapes(x).Chart
Set objChartGroups = objChart.ChartGroups(x)
Set objChartGroup = objChartGroups.Item(x)
Set objCategoriesColl = objChartGroup.CategoryCollection
Set objCategory = objCategoriesColl(x)
strCategory = objCategory.Name
I checked this property (Name) many times on Microsoft Docs (https://learn.microsoft.com/office/vba/api/powerpoint.chartcategory.name) and it is stated that it is a read/write property. However, when I try to set a new name (in the code below) I receive an error. Is it possible there's a mistake in Docs?
Public Sub EnterNewChartCats( _
lngCategoriesCount As Long, _
objCategoriesColl As CategoryCollection, _
dctDT As Dictionary, _
dctConsts As Dictionary, _
dctRegexes As Dictionary, _
dctUniques As Dictionary)
'lngCategoriesCount - number of categories in a chart
'objCategoriesColl - CategoryCollection object (a list of categories)

'dctRegexes - a dictionary for names which can be replaced using regular expressions

Dim blnInDT As Boolean

Dim blnAdd As Boolean

Dim objCategory As ChartCategory
Dim i As Long
Dim strCategory As String
Dim strUCaseToCheck As String
For i = 1 To lngCategoriesCount
Set objCategory = objCategoriesColl(i)
strCategory = Trim(objCategory.Name)
'trimmed and upper-case category string to compare with dictionary keys
strUCaseToCheck = UCase(strCategory)
'checking if a category appears in a dictionary
blnInDT = blnInDct(dctDT, strUCaseToCheck)
blnInConsts = blnInDct(dctConsts, strUCaseToCheck)
blnInRegexes = blnAnyValueLikeDctRegex(strUCaseToCheck, dctRegexes)
blnInUniques = blnInDct(dctUniques, strUCaseToCheck)
'checking if a category meets a condition - at least 1 occurrence in any dictionary
blnAdd = blnAnyValue(True, blnInConsts, blnInRegexes, blnInUniques)
'blnAlphabeticChars - a function to check if a category has any letters because
'there's no need to change such labels as '2021' etc.
If Not blnInDT And blnAdd And blnAlphabeticChars(strCategory) Then
'ERROR (objCategory.Name): Can't assign to read-only property
If blnInConsts Then
objCategory.Name = dctConsts(strUCaseToCheck)
ElseIf blnInRegexes Then
objCategory.Name = dctRegexes(strUCaseToCheck)
ElseIf blnInUniques Then
objCategory.Name = dctUniques(strUCaseToCheck)
End If
End If
Next i
Set objCategory = Nothing
End Sub
I've found a workaround (SeriesCollection(x).Values or .XValues) but it's not convenient to use. So, my question is: does exist any way to use Name to set new labels? If no - do you know other workarounds?
EDIT: I've finally managed to change labels via objChart.ChartData.Workbook but it's very slow and, more importantly, a workbook has to be activated (opened) in order to refresh categories/series names. That influenced performance and time of execution greatly so I'm still looking for any other way to do so.
Your first listing is trying to set the name of .CategoryCollection(1). But the help page that you linked to is about .ChartCategory.
In any case, here's how to set the category names:
ActivePresentation.Slides(1).Shapes(1).Chart.Axes(xlCategory).CategoryNames = Array("Test1", "Test2", "Test3", "Test4")

Listview - add File type & Last modified Subitems

I'm trying to add "file type" and "last modified" to my Listview when adding items in It same as in Explorer, but I don't find what property should be assigned to SubItem. Here is my code:
For Each MyFile As IO.FileInfo In ItemDirectory.GetFiles
Dim lvi As New ListViewItem
lvi.Tag = mFile.FullName
lvi.Text = mFile.Name
lvi.ImageKey = CacheShellIcon(mFile.FullName)
Listview1.Items.Add(lvi)
lvi.SubItems.Add("File type ??")
lvi.SubItems.Add(mFile.LastAccessTime.ToShortDateString & " " & mFile.LastAccessTime.ToShortTimeString) 'This isn't same as last modified ?
Next
If somebody knows how to do It please let me know, I want to have this in my Details view.
The linked answer provides an all-purpose way to get all the extended properties. With 300+ elements in newer Windows versions it is clearly overkill to fetch them all if you are only interested in one or two. This returns just the file type. A better approach might be to pass a "shopping list" of desired property names.
As before, you need to add a reference to Microsoft Shell Controls and Automation or Microsoft Shell Folder View Router based on your OS version.
Imports Shell32
Imports SHDocVw
Partial Friend Class Shell32Methods
Friend Shared Function GetShellFileProperty(filepath As String, index As Int32) As String
Dim shell As New Shell32.Shell
Dim shFolder As Shell32.Folder
shFolder = shell.NameSpace(Path.GetDirectoryName(filepath))
' get shell data for this file, cast to folder item
Dim shFolderItem = DirectCast(shFolder.Items().Item(Path.GetFileName(filepath)),
Shell32.ShellFolderItem)
If shFolderItem IsNot Nothing Then
Return shFolder.GetDetailsOf(shFolderItem, index)
Else
Return String.Empty
End If
End Function
...
End Class
Usage:
Dim lvi As ListViewItem
Dim fileType As String
For Each f As String In Directory.EnumerateFiles("C:\Temp\ShellTest")
fileType = Shell32Methods.GetShellFileProperty(f, 9)
lvi = New ListViewItem
lvi.Text = Path.GetFileName(f)
lvi.SubItems.Add(fileType)
lvFiles.Items.Add(lvi)
Next
Ideally, you'd want to create an Enum for the properties so the code could avoid magic numbers:
fileType = Shell32Methods.GetShellFileProperty(f, Shell32FileProps.FileType)
As noted elsewhere, the index of the ones >260 or so can change depending on the OS version. That could be easily modified to accept an Enum/Int array and return a list of values so as to prevent iterating all 300+ propertied to get one or three.
For filetype you can use lvi.SubItems.Add(MyFile.Extension)
and for the "last modified" date, of course the last modified! :D
lvi.SubItems.Add(MyFile.LastWriteTime.ToShortDateString)
Last write and last access are not the same ;)
I figured out another solution, I think this one is easier, at least for me :
Public Function ExProperty(filepath As String, PropertyItem As Integer)
Dim arrHeaders As New List(Of String)()
Dim shell As New Shell
Dim rFolder As Folder = shell.[NameSpace](Path.GetDirectoryName(filepath))
Dim rFiles As FolderItem = rFolder.ParseName(Path.GetFileName(filepath))
'I needed only File type so I looped to 2 only (2 is the file type in my case - Windows 10 -
' to see all available properties do a loop
' 0 To Short.MaxValue - 1" and then extract whatever property you like)
For i As Integer = 0 To 2
Dim value As String = rFolder.GetDetailsOf(rFiles, i).Trim()
arrHeaders.Add(value)
Next
Dim DesiredProperty As String
DesiredProperty = arrHeaders.Item(PropertyItem)
Return DesiredProperty
End Function
Usage with Listview just simply (this adds File type subitem):
Listview1_Item.SubItems.Add(ExProperty(filepath, 2))
As in all solutions, a reference to Microsoft Shell Controls and Automation must be set.

Getting data from dataset

I have got a problem, I have got a filled dataset, but now i need to get a Column value from it and store it into a variable. On Button 2 click i fill it with this:
tbaGridview.Fill(BlGridview1.vwBLcontainerCargo, Bookingnumber)
Now i want to get the data from it that is inside. I have got a for loop:
For i As Integer = 0 To GridView1.DataRowCount - 1
Dim OriginSealNumber As String = BlGridview1.vwBLcontainerCargo.Tables("SEALNUMBER").Rows(i).Item(0)
Next i
But it says Tables is not a member of windowsapplication1.blgridView.vwBLContainerCargoDataTable. How do i get the data for each column??
To reference the GridView's table use this sintax:
((DataRowView)GridView1.Rows[0].DataBoundItem).DataView.Table
But I recommend that you use a BindingSource object and iterate through it.
I fixed it myself by using this:
For i As Integer = 0 To GridView1.DataRowCount - 1
Dim OriginSealNumber As String = BlGridview1.Tables(0).Rows(i)("SEALNUMBER").ToString()
Dim OriginContainerNumber As String = BlGridview1.Tables(0).Rows(i)("CONTAINERNUMBER").ToString()
Dim OriginContainerType As String = BlGridview1.Tables(0).Rows(i)("CONTAINERTYPE").ToString()
Dim OriginQuantity As String = BlGridview1.Tables(0).Rows(i)("QUANTITY").ToString()
Dim OriginPackageType As String = BlGridview1.Tables(0).Rows(i)("PACKAGETYPE").ToString()
Dim OriginDescription As String = BlGridview1.Tables(0).Rows(i)("DESCRIPTION").ToString()
Dim OriginWeight As String = BlGridview1.Tables(0).Rows(i)("WEIGHT").ToString()
Next i

Get RepositoryItem (As Control) From Devexpress-GridviewCell

I'm using the devexpress Gridcontrol/Gridview which has 4 columns
Name: String
Description: String
Action: RepositoryItemLookUpEdit
Info: RepositoryItemHyperLinkEdit
Right now i want to write a function which updates the Action-column but only if the Value is contained in the datasource of the RepositoryItemLookUpEdit
So i started writing the code and this is how i far i got:
For i As Integer = 0 To GridViewDD.RowCount - 1
Dim j As Integer = i
Dim rItemlookup As RepositoryItemLookUpEdit = CType(GridViewDD.GetRow(i), DataRowView).Item("Actions")
If CType(rItemlookup.DataSource, List(Of String)).Contains(curraction) Then
// Do update of the datasource here (which works)
End If
Next
GridControlDD.RefreshDataSource()
My problem lies at the line:
Dim rItemlookup As RepositoryItemLookUpEdit = CType(GridViewDD.GetRow(i), DataRowView).Item("Actions")
Question:
How can i get the RepositoryItemLookUpEdit of a cell in devexpress (or its datasource)?
Note:
The datasource of my gridview (GridViewDD) is a List And my datasource of the RepositoryItemLookUpEdit in Action is always a List(Of String)
Note 2:
The contents of my datasource may vary from row to row
You can easily get your RepositoryItem from GridColumn.ColumnEdit property.
Here is example:
Dim rItemlookup As RepositoryItemLookUpEdit = GridViewDD.Columns("Action").ColumnEdit
'...
For i As Integer = 0 To GridViewDD.RowCount - 1
Dim j As Integer = i
If CType(rItemlookup.DataSource, List(Of String)).Contains(curraction) Then
'... Do update of the datasource here (which works)
End If
Next
GridControlDD.RefreshDataSource()
I've found it. thanks to 'many' hours of browsing the devexpress-forums. Using Gridviewinfo and GridDataRowInfo you can easily access the controls 'hidden' inside the grid
In my case the code looks as following
Dim gvInfo As GridViewInfo = GridViewDD.GetViewInfo()
Dim rInfo As GridDataRowInfo = gvInfo.RowsInfo.FindRow(i)
Dim rItemlookup As RepositoryItemLookUpEdit = rInfo.Cells(GridViewDragDrop.Columns.Item("Actions")).Editor
you can now use rItemlookup to change or access its properties.
I hope this may be of some use to anyone.

VB Script code to read column value from lotus notes database

Set domSession = CreateObject("Notes.NotesSession")
Dim domDatabase
Set domDatabase = domSession.GetDatabase("server Name", "xyz.nsf")
Set domView = domDatabase.GetView("All Projects")
Up to here it's ok. But I try lot but unable to read the document values.
I am looking for the vbscript code to read the document data.
Add this:
Dim i%
Dim s$
Dim doc As Object
For i% = 1 to domView.EntryCount
Set doc = domView.GetNthDocument(i%)
s$ = doc.GetItemValue("itemname")(0)
' Do whatever you want with the string value which is now stored in s$
Next
This code assumes the items are text type. You could use simply Dim s to get any item type (number, date).
To get column values from the view you can use doc.ColumnValues(2). This returns the value of 3rd column (0 is first).
