How to add pictures to RichTextBox in a loop? - vb.net

I am adding different arrays of strings to a RichTextBox and I want to insert pictures too. I searched for a method and they all say Paste it. I tried that but it doesn't work in a loop.
Dim df As DataFormats.Format = DataFormats.GetFormat(DataFormats.Bitmap)
for i as integer = 0 to 50
RTF1.text = RTF1.text & arr1(i) & arr2(i) & vbnewline
Dim bmp As New Bitmap(picarr(i))
Clipboard.SetImage(bmp)
RTF1.Paste(df)
next i
I also tried SendKeys because when I press Ctrl+V, it pastes the picture. Also, I tried to exit the loop and it pastes the last image only.

Every time you set the RichTextBox.Text property, you lose all the RTF data it previously contained (including formatting, images, etc.) and you're only maintaining the plain text (because of = RTF1.Text & ...).
Instead, use the AppendText() method like this:
Dim df As DataFormats.Format = DataFormats.GetFormat(DataFormats.Bitmap)
For i As Integer = 0 To 50
RTF1.AppendText(arr1(i) & arr2(i) & vbNewLine)
Using bmp As New Bitmap(picarr(i))
Clipboard.SetImage(bmp)
End Using
RTF1.Paste(df)
Next

Using swModel.CreateText for multiline notes with checkboxes

I'm writing a macro that takes multiple checkboxes and loops through them to insert the standard notes into a single note. This is my code:
This is what I have. What it should be doing is taking each checkbox caption and adding it to a new line in a single note. What it's doing is creating a new note for each caption with a space at the end. I've tried moving that line of code around, but this is my first time using VBA and I've ran out of ideas. What can I do to have it create a single note and adaptively add all chosen captions into it?
The CreateText shouldn't be in the For loop
Try this:
Dim MyStr As String
For Each ThisControl2 In Prompt.Controls
If TypeName(ThisControl2) = "CheckBox" Then
If ThisControl2.Value = True Then
MyStr = Mystr & ThisControl2.Caption & vbCrLf
End If
End If
Next
swModel.CreateText MyStr, 0.02, 0.02, 0, 0.003175, 0

Changing text in a contentcontrol is very slow

I have a big table in ms-word that contains 85 contentcontrols (combo boxes). I want to change the content using a vba loop (see below). It takes longer than one minute for it to complete...
Are there other options?
Private Sub Btn_Clear1_Click()
Dim a
Dim c As ContentControl
a = FindTable(ActiveDocument.Name, "myTableName")(1) 'returns an array(Long) with number of table found
For Each c In ActiveDocument.Tables(a).Range.ContentControls
c.Range.text = "MY CHANGED TEXT"
Next c
End Sub
Thanks in advance for any hint!
Here, turning off screenupdating reduces the time from about 6 seconds to less than 1 second. e.g.
On Error Goto turnscreenon
Application.Screenupdating = False
For Each c In ActiveDocument.Tables(a).Range.ContentControls
c.Range.text = "MY CHANGED TEXT"
Next c
turnscreenon:
Application.Screenupdating = True
That may only work on the Windows version of Word.
If you know exactly how many combo boxes there are going to be, you could consider creating a custom xml part containing an array of XML Elements to contain the values. Map each content control to one of those elements. Then instead of writing the values to the content control ranges, write them to the XML Part and let Word do the work. That works almost instantaneously here.
e.g. in a simple scenario where you just have those 85 content controls in the table, you could set up the Custom XML Part like this (I leave you to write any code that you need to delete old versions). You should only need to run this once.
Sub createCxpAndLink()
' You should choose your own Uri
Const myNamespaceUri As String = "mycbcs"
Dim a
Dim i As Long
Dim s As String
Dim cxp As Office.CustomXMLPart
With ActiveDocument
a = FindTable(.Name, "myTableName")(1)
s = ""
s = s & "<?xml version='1.0' encoding='UTF-8'?>" & vbCrLf
s = s & "<cbcs xmlns='" & myNamespaceUri & "'>" & vbCrLf
For i = 1 To .Tables(a).Range.ContentControls.Count
s = s & " <cbc/>" & vbCrLf
Next
s = s & "</cbcs>"
Set cxp = .CustomXMLParts.Add(s)
With .Tables(a).Range.ContentControls
For i = 1 To .Count
.Item(i).XMLMapping.SetMapping "/x:cbcs[1]/x:cbc[" & Trim(CStr(i)) & "]", "xmlns:x='" & myNamespaceUri & "'", cxp
Next
End With
Set cxp = Nothing
End With
End Sub
Then to update the contents you need something like this
Sub testsetxml()
Const myNamespaceUri As String = "mycbcs"
Dim i As Long
'our start time...
Debug.Print Now
With ActiveDocument.CustomXMLParts.SelectByNamespace(myNamespaceUri)(1)
For i = 1 To 85
.SelectNodes("/ns0:cbcs[1]/ns0:cbc[" & Trim(CStr(i)) & "]")(1).Text = "my changed text "
' or if you want to put different texts in different controls, you can test using e.g.
.SelectNodes("/ns0:cbcs[1]/ns0:cbc[" & Trim(CStr(i)) & "]")(1).Text = "my changed text " & Cstr(i)
Next
End With
'our end time...
Debug.Print Now
End Sub
(NB you cannot do it by mapping all the controls to a single XML element because then all the dropdowns will all be updated to the same value whenever you change the value of one of them.)
Apologies for any typos - I've changed the code to be more in line with what you have already and have not tested the changes.

What does a hyperlink range.start and range.end refer to?

I'm trying to manipulate some text from a MS Word document that includes hyperlinks. However, I'm tripping up at understanding exactly what Range.Start and Range.End are returning.
I banged a few random words into an empty document, and added some hyperlinks. Then wrote the following macro...
Sub ExtractHyperlinks()
Dim rHyperlink As Range
Dim rEverything As Range
Dim wdHyperlink As Hyperlink
For Each wdHyperlink In ActiveDocument.Hyperlinks
Set rHyperlink = wdHyperlink.Range
Set rEverything = ActiveDocument.Range
rEverything.TextRetrievalMode.IncludeFieldCodes = True
Debug.Print "#" & Mid(rEverything.Text, rHyperlink.Start, rHyperlink.End - rHyperlink.Start) & "#" & vbCrLf
Next
End Sub
However, the output between the #s does not quite match up with the hyperlinks, and is more than a character or two out. So if the .Start and .End do not return char positions, what do they return?
This is a bit of a simplification but it's because rEverything counts everything before the hyperlink, then all the characters in the hyperlink field code (including 1 character for each of the opening and closing field code braces), then all the characters in the hyperlink field result, then all the characters after the field.
However, the character count in the range (e.g. rEverything.Characters.Count or len(rEverything)) only includes the field result if TextRetrievalMode.IncludeFieldCodes is set to False and only includes the field code if TextRetrievalMode.IncludeFieldCodes is set to True.
So the character count is always smaller than the range.End-range.Start.
In this case if you change your Debug expression to something like
Debug.Print "#" & Mid(rEverything.Text, rHyperlink.Start, rHyperlink.End - rHyperlink.Start - (rEverything.End - rEverything.Start - 1 - Len(rEverything))) & "#" & vbCrLf
you may see results more along the lines you expect.
Another way to visualise what is going on is as follows:
Create a very short document with a piece of text followed by a short hyperlink field with short result, followed by a piece of text. Put the following code in a module:
Sub Select1()
Dim i as long
With ActiveDocument
For i = .Range.Start to .Range.End
.Range(i,i).Select
Next
End With
End Sub
Insert a breakpoint on the "Next" line.
Then run the code once with the field codes displayed and once with the field results displayed. You should see the progress of the selection "pause" either at the beginning or the end of the field, as the Select keeps "selecting" something that you cannot actually see.
Range.Start returns the character position from the beginning of the document to the start of the range; Range.End to the end of the range.
BUT everything visible as characters are not the only things that get counted, and therein lies the problem.
Examples of "hidden" things that are counted, but not visible:
"control characters" associated with content controls
"control characters" associated with fields (which also means hyperlinks), which can be seen if field result is toggled to field code display using Alt+F9
table structures (ANSI 07 and ANSI 13)
text with the font formatting "hidden"
For this reason, using Range.Start and Range.End to get a "real" position in the document is neither reliable nor recommended. The properties are useful, for example, to set the position of one range relative to the position of another.
You can get a somewhat more accurate result using the Range.TextRetrievalMode boolean properties IncludeHiddenText and IncludeFieldCodes. But these don't affect the structural elements involved with content controls and tables.
Thank you both so much for pointing out this approach was doomed but that I could still use .Start/.End for relative positions. What I was ultimately trying to do was turn a passed paragraph into HTML, with the hyperlinks.
I'll post what worked here in case anyone else has a use for it.
Function ExtractHyperlinks(rParagraph As Range) As String
Dim rHyperlink As Range
Dim wdHyperlink As Hyperlink
Dim iCaretHold As Integer, iCaretMove As Integer, rCaret As Range
Dim s As String
iCaretHold = 1
iCaretMove = 1
For Each wdHyperlink In rParagraph.Hyperlinks
Set rHyperlink = wdHyperlink.Range
Do
Set rCaret = ActiveDocument.Range(rParagraph.Characters(iCaretMove).Start, rParagraph.Characters(iCaretMove).End)
If RangeContains(rHyperlink, rCaret) Then
s = s & Mid(rParagraph.Text, iCaretHold, iCaretMove - iCaretHold) & "" & IIf(wdHyperlink.TextToDisplay <> "", wdHyperlink.TextToDisplay, wdHyperlink.Address) & ""
iCaretHold = iCaretMove + Len(wdHyperlink.TextToDisplay)
iCaretMove = iCaretHold
Exit Do
Else
iCaretMove = iCaretMove + 1
End If
Loop Until iCaretMove > Len(rParagraph.Text)
Next
If iCaretMove < Len(rParagraph.Text) Then
s = s & Mid(rParagraph.Text, iCaretMove)
End If
ExtractHyperlinks = "<p>" & s & "</p>"
End Function
Function RangeContains(rParent As Range, rChild As Range) As Boolean
If rChild.Start >= rParent.Start And rChild.End <= rParent.End Then
RangeContains = True
Else
RangeContains = False
End If
End Function

How do I stop Word from selecting each FormField as I read their values in VBA?

I have a template document in Word 2013 that has the user fill in a large number of Legacy Text FormFields. At the end of the document, I've included a button which compiles the answers into a string devoid of formatting, then copies it to the clipboard.
It works, but as each FormField is read, the Word document skips back and forth between each text field and the end of the document. It's visually alarming. Is there a way to gather the values of each FormField without Word moving the cursor/focus to each field as it is read?
Here's a sample of the code:
Private Sub cmdCreateNote_Click()
Call cmdClearNote_Click
Dim ff As FormFields
Set ff = ActiveDocument.FormFields
Dim Output As String
Output = ff("ddReviewType").Result & vbCrLf
If ff("chFacInfo").Result Then
Dim FacInfo
FacInfo = Array("Field1: ", _
"Field2: ", _
"Field3: ", _
"Field4: ", _
"Field5: ")
Output = Output & "FIRST SECTION" & vbCrLf
For Index = 1 To 5
If ff("chFacInfo" & Index).Result Then
Output = Output & FacInfo(Index - 1) & ff("txFacInfo" & Index).Result & vbCrLf
End If
Next
Output = Output & vbCrLf
End If
Dim FORange As Range
Set FORange = ActiveDocument.Bookmarks("FinalOutput").Range
FORange.Text = Output
ActiveDocument.Bookmarks.Add "FinalOutput", FORange
Selection.GoTo What:=wdGoToBookmark, Name:="FinalOutput"
Selection.Copy
End Sub
It appears that every time I access ActiveDocument.FormFields( x ).Result, the document focus goes to that element, then drops back to the end of the document again.
Any pointers?
Use the Bookmark object instead of the FormField. This will allow you to access the properties without changing the screen focus. See answer on Suppress unwanted jumping/scrolling on Word 2013 VBA Script for specifics on how to do this.
ActiveDocument.Bookmarks("myFieldName").Range.Fields(1).Result
Posting comment as answer, since it worked!
Try Application.ScreenUpdating = False before going through the FormFields and then setting it to True after, in order to minimize screen updating.

Multi-Select Files Into Array VB.Net

I am working on a program where I need the user to select two files from an OpenFileDialog. I don't want to hardcode the file names or paths into the program. I need the contents of these files to display into two columns in a List Box.
So far I have the following code:
OpenFileDialog.ShowDialog()
OpenFileDialog.Filter = "Text Files(.txt)|*.txt"
OpenFileDialog.Title = "Open A Text File"
OpenFileDialog.Multiselect = True
Dim FileArray(1) As String
Dim objreader As New System.IO.StreamReader(OpenFileDialog.FileName)
Dim i = 0
ListBox1.Items.Clear()
ListBox1.Items.Add("Name" & Space$(40) & "ID Number")
Do While objreader.Peek() <> -1
If OpenFileDialog.FileNames.Length = 5 Then
FileArray(0) = objreader.ReadLine & vbCr
Else
FileArray(1) = objreader.ReadLine & vbCr
End If
ListBox1.Items.Add(FileArray(0) & Space$(40) & FileArray(1))
Loop
What I think is happening is the first selected file, 'Names.txt' is being fed into FileArray(0) (because the length of the file name is 5 characters), and then being populated into the correct column in the list box.
However, as it loops a second time, the second file, 'IDNumbers.txt', is read and populated into FileArray(1) (because it fails the 'If') and is overwriting the first array in the list box.
My question is how can I load each file into its own element in my FileArray(1), so I can load them correctly into the ListBox and later manipulate the data?
