I have a frustrating problem. I have a string containg other characters that are not in this list (check link). My string represents a SQL Query.
This is an example of what my string can contain: INSERT INTO test (description) VALUES ('≤ ≥ >= <=')
When I check the database, the row is inserted successfully, but the characters "≤" and "≥" are replaced with "=" character.
In the database the string in description column looks like "= = >= <=".
For the most characters I can get a character code. I googled a character code for those two symbols, but I didn't find one. My goal is to check if my string contains this two characters , and afterwards replace them with ">=" and "<="
===Later Edit===
I have tried to check every character in a for loop;
tmp = Mid$(str, i, 1)
tmp will have the value "=" when my for loop reaches the "≤" character, so Excel cannot read this "≤" character in a VB string, then when I'm checking for character code I get the code for "=" (Chr(61))
Are you able to figure out what the character codes for both "≤" and "≥" in your database character set are? if so then maybe try replacing both characters in your query string with chrw(character_code).
I have just tested something along the lines of what you are trying to do using Excel as my database - and it looks to work fine.
Edit: assuming you are still stuck and looking for assistance here - could you confirm what database you are working with, and any type information setting for the "description" field you are looking to insert your string into?
Edit2: I am not familiar with SQL server, but isn't your "description" field set up to be of a certain data type? if so what is it and does it support unicode characters? ncharvar, nchar seem to be examples of sql server data types that support Unicode.
It sounds like you may also want to try and add an "N" prefix to the value in your query string - see
Do I have use the prefix N in the "insert into" statement for unicode? &
how to insert unicode text to SQL Server from query window
Edit3: varchar won't qualify for proper rendering of Unicode - see here What is the difference between varchar and nvarchar?. Can you switch to nvarchar? as mentionned above, you may also want to prefix the values in your query string with 'N' for full effect
Edit4: I can't speak much more about sqlserver, but what you are looking at here is how VBA displays the character, not at how it actually stores it in memory - which is the bottom line. VBA won't display "≤" properly since it doesn't support the Unicode character set. However, it may - and it does - store the binary representation correctly.
For any evidence of this, just try and paste back the character to another cell in Excel from VBA, and you will retrieve the original character - or look at the binary representation in VBA:
Sub test()
Dim s As String
Dim B() As Byte
'8804 is "≤" character in Excel character set
s = ChrW(8804)
'Assign memory representation of s to byte array B
B = s
'This loop prints "100" and "34", respectively the low and high bytes of s coding in memory
'representing binary value 0010 0010 0110 0100 ie 8804
For i = LBound(B) To UBound(B)
Debug.Print B(i)
Next i
'This prints "=" because VBA can not render character code 8804 properly
Debug.Print s
End Sub
If I copy your text INSERT INTO test (description) VALUES ('≤ ≥ >= <=') and paste it into the VBA editor, it becomes INSERT INTO test (description) VALUES ('= = >= <=').
If I paste that text into a Excel cell or an Access table's text field, it pastes "correctly".
This seems to be a matter of character code supported, and I suggest you have a look at this SO question.
But where in you program does that string come from, since it cannot be typed in VBA ??
Edit: I jus gave it a try with the below code, and it works like a charm for transferring your exotic characters from the worksheet to a table !
Sub test1()
Dim db As Object, rs As Object, cn As Object
Set cn = CreateObject("DAO.DBEngine.120")
Set db = cn.OpenDatabase("P:\Database1.accdb")
Set rs = db.OpenRecordset("table1")
With rs
.addnew
.Fields(0) = Range("d5").Value
.Update
End With
End Sub

I have a text field in a table where I need to substitute phone numbers where applicable.
For example the text field could have:
Call me on 08588812885 immediately
Call me on 07525812845
I need assistance please contact me
Good service
Sometimes a phone number will be in the text but not always and the phone number entered will always be different.
Is there a measure to use to replace the phone numbers with no text.
Ideally the solution would be Power BI, but can also be done in the raw data using excel or VBA
Regular expression in VBA (excel) or Python (Power BI) is a straightforward solution.
I have never used PowerBI with Python before but manage to make following python script.
In PowerBI transformation steps I created a new column that would copy [message] columns and named it [noPhoneNumber], then next step ran this python script
import re
def removePhone(x):
return re.sub('\d{10,11}', "**number removed**", x)
length = len(dataset["noPhoneNumber"])
for iRow in range(length):
dataset["noPhoneNumber"][iRow] = removePhone(dataset["noPhoneNumber"][iRow])
so column "noPhoneNumber"
Call me on 08588812885 immediately
Call me on 07525812845
I need assistance please contact me
Good service
becomes
Call me on **number removed** immediately
Call me on **number removed**
I need assistance please contact me
Good service
In VBA Preferable create UDF (user defined function) and don't create a subroutine, that would be too error prone for this kind of problem.
[Added]
If you need to make a Excel based solution, you can create a UDF function like so:
(remember early binding to import of VBScript_RegExp_55.RegExp in excel)
Function removePhoneNumber(text As String, Optional replacement As String = "**number removed**") As String
Dim regex As New RegExp
regex.Pattern = "\d{10,11}"
removePhoneNumber = regex.Replace(text, replacement)
End Function
...and then use excel function like so:
=removePhoneNumber(A2),
=removePhoneNumber(A3)
and so on...
A simple VBA function alternative
Function removePhone(s As String) As String
Const DELIM As String = " "
Dim i As Long, tokens As Variant
tokens = Split(s, DELIM)
For i = LBound(tokens) To UBound(tokens)
If IsNumeric(tokens(i)) Then
tokens(i) = "*Removed*" ' << change to your needs
Exit For ' assuming a single phone number per string
End If
Next
removePhone = Join(tokens, DELIM)
End Function
You can do this in Power Query. Create a custom column with this below code. I have considered the column name is Comments but please adjust this with your column name.
if Text.Length(Text.Select([comments], {"0".."9"})) = 11
then
Text.Replace(
[comments],
Text.Select([comments], {"0".."9"}),
""
)
else [comments]
Here is the output below. You can also replace phone numbers with other text like #### to make is anonymous.
NOTE
This will only work if there are only 1 number in the string with length 11 (You can adjust the length in code as per requirement).
This will Not work if there are more than one Numbers in the string.
If there are 1 number in the string but length not equal 11, this will keep the whole string as original.
I am trying to find out how I should deal with a named column in myTable which contains a commercial at (#) in its name, e.g. active # mail. This code is supposed to print the column number in the Immediate output window:
Sub teststring()
Dim s As String
s = ActiveSheet.Range("myTable[active # mail]").Column
Debug.Print s
End Sub
but it fails. Using .Range("myTable[active" & Chr(64) "& mail]") fails as well.
You can do it like this:
s = ActiveSheet.listobjects("myTable").listcolumns("active # mail").Range.Column
See also https://support.office.com/en-us/article/using-structured-references-with-excel-tables-f5ed2452-2337-4f71-bed3-c8ae6d2b276e for how to escape special characters
So:
s = ActiveSheet.Range("myTable[active '# mail]").Column
will also work.
# has a special meaning in structured references, so you can't use it in a column name without escaping it with ' (a single quote)
I wrote an export to CSV file in my vb.net application, and I then exported it into Outlook.
The issue I've got, is that when the CSV file is being written, my code is checking for a comma in the current field, but while doing this, it also mistakes a double space for a comma, or space followed by 'Enter' key being pressed (for multiline textboxes)
An example would be if in the notes section of the customer, there is 4 lines of text, and one ends in a space - The user has then pressed enter to go to the next line, however the program is taking the next line of text and creating a new record for it, as it thinks it's a comma...
What is the reason for this? This means that data has to be super validated (ie checking for no double spaces etc) before it can be exported, which is far too time consuming.
Hopefully this makes sense!
This is the code:
Dim result As Boolean = True
Try
Dim sb As New StringBuilder()
Dim separator As String = ","
Dim group As String = """"
Dim newLine As String = Environment.NewLine
For Each column As DataColumn In dtable.Columns
sb.Append(wrapValue(column.ColumnName, group, separator) & separator)
Next
sb.Append(newLine)
For Each row As DataRow In dtable.Rows
For Each col As DataColumn In dtable.Columns
sb.Append(wrapValue(row(col).ToString(), group, separator) & separator)
Next
sb.Append(newLine)
Next
The code for wrapValue
Function wrapValue(value As String, group As String, separator As String) As String
If value.Contains(separator) Then
If value.Contains(group) Then
value = value.Replace(group, group + group)
End If
value = group & value & group
End If
Return value
End Function
Based on the fact that it's shortening it by 430 lines, I'd suggest it's something to do with the fact you're adding a load of "" before and after the value variable.
If it's removing a value at the start, then it will be removing a " before the first column header. As to why it's importing one record as you mentioned in the comments, I'm not entirely sure, however, I would suggest the issue lies in your wrapValue code.
Can you try changing
value = group & value & group
to
value = value
and see if that changes anything?
I would like to be able to split a string of text that has been entered into a textbox on a MS Access form and store the split strings as separate records under the same field. This is the code I have so far, but I keep running into problems at every corner. I'm fairly new to this, but have been learning quickly. Any help is appreciated.
Here is what I'd like to accomplish: If I enter the following text into a text box ("this is a sentence") and click submit. I would like each other the words to be stored as individual records under a common field. Seems simple, but it's causing quite a few headaches.
Private Sub Submit_Click()
Dim SetDBConnection As ADODB.Connection
Set SetDBConnection = CurrentProject.Connection
Dim strInsertRecord As String
Dim strNewPhrase As String
Dim strStorePhrase As String
strNewPhrase = textPhrase
strStorePhrase = Split(NewPhrase)
strInsertRecord = "INSERT INTO [FieldSplice] (words) VALUES (" & strStorePhrase & ")"
SetDBConnection.Execute strInsertRecord
textPhrase.Value = Null
End Sub
I'm a little unclear on why you have the ADODB connection... is this connecting to an external database? If so, that makes sense, but then you are missing some code to get the insert to work properly.
If this is just an internal (native) Access table, then I don't think you need any of that. Here is a simple example of how you would take a string, split it into words (based on a space) and then insert those into your table:
Dim textPhrase As String
Dim words() As String
Dim i As Integer
textPhrase = "This is a test"
words = Split(textPhrase, " ")
sql = "parameters P1 text; INSERT INTO [FieldSplice] (words) VALUES ([P1])"
Set query = CurrentDb.CreateQueryDef("FsInsert", sql)
For i = LBound(words) To UBound(words)
query.Parameters("P1").Value = words(i)
query.Execute
Next i
CurrentDb.QueryDefs.Delete ("FsInsert")
One other note of interest -- you don't need to declare the insert each time. You can set a parameter, assign values to the parameter and execute the insert command multiple times. This is included in my example above.
Your code was trying to say:
insert into [table] (field) values ("value1", "value2", "value3")
Which you can't do. That has to be done as three inserts, unless your database supports array inserts (Oracle, for example).
The multiple fields only works like this:
insert into [table] (field1, field2) values ("value1", "value2")
Where each value corresponds to a column in the table.
I found the article about putting excel cells into an email using the RangetoHTML function in VBA. It works like a charm, but now I’m facing a Problem.
If there are Umlaut (e.g.: ü, ä, ö) in the cells the result in the email shows strange symbols (e.g.: ä, …).
I looked up the written temp.htm file. On the first view of this file, it seems the umlaute are correctly written, but after looking through the file with an hex editor i found that the written symbols are not correct.
The function which writes the file is: PublishObjects.Add
So I hope someone can help me with this.
Edit: Added a testfile. Word and Office is needed.
Select the table and run the procedure SendMail.
You will always have problems with vba and foreign chars and the web.
EDIT:
Because you can't separate the cell values from the html the function below will unfortunately not work in this situation. BUT:
if you Save a copy of the document with western European windows encoding it will work.
(See comments below).
To be able to do that you press "Save As" and there is a dropdown on the left side of the save button (Tools) which will give you a dialog where you can change the encoding.
The image has ben lifted from technet and always save web.. is not necessary.
EOF EDIT:
This is a function I have used, Unfortunately can't remember who I got it from, But its from the olden days of vba and classic asp
Put your email cell formula into this function and it should work because all the letters are html encoded. Its slow and makes a bad overhead. But it will work.
Function HtmlEncode(ByVal inText As String) As String
Dim i As Integer
Dim sEnc As Integer
Dim repl As String
HtmlEncode = inText
For i = Len(HtmlEncode) To 1 Step -1
sEnc = Asc(Mid$(HtmlEncode, i, 1))
Select Case sEnc
Case 32
repl = " "
Case 34
repl = """
Case 38
repl = "&"
Case 60
repl = "<"
Case 62
repl = ">"
Case 32 To 127
'Numbers
Case Else
repl = "&#" & CStr(sEnc) & ";" 'Encode it all
End Select
If Len(repl) Then
HtmlEncode = Left$(HtmlEncode, i - 1) & repl & Mid$(HtmlEncode, i + 1)
repl = ""
End If
Next
End Function
