With that I have to update that string into grid column value with same datatype declared still giving error datatype mismatch during fied update .
I had tried this line of code to replace :
Replace(string,vbNewLine," ")
And for updating the code is
Gridview.Columns.Items(3).value=string

In Excel VBA, how do I refer to a named column that contains a single quote

I am investigating a bug in an Excel spreadsheet where the following formula is inserted into every cell in a column.
=AGGREGATE( 3, 5, InputData[#[Foo]:[Bar]]) > 0
The VBA is as follows:
Let AddColumn.DataBodyRange.formula = "=AGGREGATE( 3, 5, [#[Foo]:[Bar]]) > 0"
this will evaluate to FALSE if all of the cells on the current row between columns Foo and Bar are empty, otherwise it evaluates to TRUE
The problem I'm seeing is that the names Foo and Bar are variable and not under my control and the formula fails with Run-time error 1004 if a name contains a single quote:
Let AddColumn.DataBodyRange.formula = "=AGGREGATE( 3, 5, [#[Foo's name]:[Bar]]) > 0"
Is there a way I can escape the name in such a way that single quotes won't create the run-time error? Adding double quotes around the name gives me the same error.
Are there likely to be further problems if the names contain other characters that have special meaning in Excel?
I could also refer to the columns by address instead of name. Would that work with the current row '#' notation?

I hear you when you say the naming convention is "not under my control". This really puts you in a bind when anything can be pumped into your code.
Sadly, the only solution is to scrub the input when they finally hand it over to you. This involves you having to make your own vba function that takes in a string and returns a string that has special characters removed (or replaced with something else).
In your case, you are going to have to scrub the data in possibly two places.
First, you will need to change all the column names so they don't have special characters in them. You'll need to access each name and send it through the 'scrub' function and then replace the name with the scrubbed name.
Second, when someone inputs a column name for your AGGREGATE, you'll need to capture that input into a string variable and then pass that through the 'scrub' function. Then you'll need to validate that the input they gave you matches up with a valid column name. If it's not valid, send them an error message asking them to enter a valid name or to cancel out.
After you have valid values for foo and bar, you can add them to your AGGREGATE function and let it execute.
If you can't scrub/change your column names, then you'll have to make a list of scrubbed column names and associate them with the column address. Then when you get your input, scrub it, and then match to the list to grab the correct address. Then you can use hard addresses instead of variable naming schemes.
It's a lot of work. But it's necessary when you have naming conventions that are not under your control.
The other answers and comments put me on the right track:
Function escapedColumnName(columnName As String) As String
columnName = Replace(columnName, "'", "''")
columnName = Replace(columnName, "#", "'#")
columnName = Replace(columnName, "[", "'[")
columnName = Replace(columnName, "]", "']")
escapedColumnName = columnName
End Function

MS Access 2016 vba: Empty value passed from form field (text box)

I'm having a strange situation:
I have a simple form with 2 text boxes.
The second one has the vba code triggered after being updated.
For example: typing value to the first field, ENTER, typing value into the second field, ENTER and the code starts.
The code, initially, takes the values from the text boxes and assign them to the string variables (pre declared as strings), like:
test1 = Me.frmSSN.Value
The problem is, the test1 variable seems to be empty after the line above.
It seems to happen only when I type, for example this string:
073QB8KJ2D00A4X
It works fine, when entering CNB0K2W5JK
The tool is a simple serial number comparison.
Just for test, I've entered this line into the code:
aaa="073QB8KJ2D00A4X"
When running in the step-by-step mode and hovering mouse over the "aaa" I'm getting: aaa= and then nothing.
Not even single "" like aaa="" or so. Just aaa=
After retrying multiple things - I believe it's about the value I enter:
073QB8KJ2D00A4X
Could be, that for access/vba it's some control string or so?
I'm just dumb now...
Thanks in advance for any help

p.s. Source fields are plain text boxes. And here's the code:
Dim user As String
Dim 1stSN As String
Dim 2ndSN As String
1stSN = Me.frmSSN.Value
2ndSN = Me.frmHPSN.Value
Then the values are being used as a part of SQL query. The problem is - in this situation - query doesn't work, as the sql string looks like:
"Select * From sbo_SerialSource where SN like " and nothing after "like".
Debug shows the correct value (with serial number), but query fails with "syntax error" message. Seems like there are some strange "control characters" are being created/added.
That's it.
And I have to use the serial numbers as these "strange ones", because that's how they come from the vendor.

Crystal Reports Display String Formula Error

I have an application which is running over hundred of system , I am facing an error in formula statement and only the best and optimal solution to change in Stored Procedure rather change in Report DLL .
Below i m attaching the screen shots , If any body suggest the best solution.
When Gross < 0 then this error occures.
any body suggest the solution
You are getting the error because the string you are converting to number doesn't have any numeric value as string but it contains string characters...
You are again converting Number to String after converting to number... why this multiple conversions.. instead use string value directly..
If you still want to do the same way then suggested approach is to check first with IsNumeric and then convert to number.
Main thing to consider is what does the variable String contains if Gross<0

Visual Basic pulling a character from a certain line number

I am working on a macro that needs to be able to check and make sure that a character on a certain line is what it should be before it finishes the form.
Where or how do i find the information to do this?
I have tried using the command "Left(#of line ,1)" and am not getting it to return anything at this point.
I Assume that you have this text in a string. Comment to my answer if wrong.
You can use a Regex to compare to string with your character like so :
If Regex.IsMatch(MyString, *.{X}Y) Then
'You have to manually replace X for the number of characters before the character you scan for
'You have to manually replace Y for the-said character it is supposed to be
Look at http://www.codeproject.com/Articles/9099/The-Minute-Regex-Tutorial for more info on Regex.
If you want to only take one line in your string :
TheLine = split(MyString,Environnement.Newline)([Line Number])

Handling ⅝ (five eights) Vulgar fraction as part of a string in VBA

As part of an access application, i retrieve data from sql server. I have a string field that contains ⅝ in one of the rows, and when i attempt to insert that value into an MsAccess recordset, i get an error
Multiple-step operation generated errors. Check each status value. Here is my code
sFieldValue = getValue() ' when i add a watch, the '⅝' is replaced by a ? e.g. "The result is ⅝" will be shown as "The result is ?"
Rs(sFieldName) = sFieldValue ' error is thrown
I then attempted to hard code the value in VBA
sFieldValue ="⅝"
And the moment i type '⅝' it automatically changes to a question mark
sFieldValue ="?"
I would like to know how i can support characters such as "⅝". The other fractions work just fine, e.g. '½'. I do not want to do any calculations, the fractions are part of a string that comes from a SQL Server, and the problem is, i get a runtime error when i try to add a string value that contains a fraction to a recordset in access.
from this page, it shows that some fractions are supported in utf-8
The problem was that the field type of Rs(sFieldName) was adVarChar. So to fix the problem, i used a adVariant field type in my recordset, and it now accepts the ⅝ vulgar character.
I am creating the recordset on the fly.
Edit: adVarWChar is more appropriate, see comment below
