I just need to know how to have plain text and a variable in a messagebox.
For example:
I can do this: MsgBox(variable)
And I can do this: MsgBox("Variable = ")
But I can't do this: MsgBox("Variable = " + variable)
This question is related to
vb.net
messagebox
As has been suggested, using the string.format method is nice and simple and very readable.
In vb.net the " + " is used for addition and the " & " is used for string concatenation.
In your example:
MsgBox("Variable = " + variable)
becomes:
MsgBox("Variable = " & variable)
I may have been a bit quick answering this as it appears these operators can both be used for concatenation, but recommended use is the "&", source http://msdn.microsoft.com/en-us/library/te2585xw(v=VS.100).aspx
maybe call
variable.ToString()
update:
Use string interpolation (vs2015 onwards I believe):
MsgBox($"Variable = {variable}")
MsgBox("Variable {0} " , variable)
I kind of run into the same issue. I wanted my message box to display the message and the vendorcontractexpiration. This is what I did:
Dim ab As String
Dim cd As String
ab = "THE CONTRACT FOR THIS VENDOR WILL EXPIRE ON "
cd = VendorContractExpiration
If InvoiceDate >= VendorContractExpiration - 120 And InvoiceDate < VendorContractExpiration Then
MsgBox [ab] & [cd], vbCritical, "WARNING"
End If
Why not use:
Dim msg as String = String.Format("Variable = {0}", variable)

I wanto to display the count of rows in the excel sheet after the filter option has been applied.
So I declared the count of last rows as a variable that can be added to the Msgbox
Sub lastrowcall()
Dim hm As Worksheet
Dim dm As Worksheet
Set dm = ActiveWorkbook.Sheets("datecopy")
Set hm = ActiveWorkbook.Sheets("Home")
Dim lngStart As String, lngEnd As String
lngStart = hm.Range("E23").Value
lngEnd = hm.Range("E25").Value
Dim last_row As String
last_row = dm.Cells(Rows.Count, 1).End(xlUp).Row
MsgBox ("Number of test results between the selected dates " + lngStart + "
and " + lngEnd + " are " + last_row + ". Please Select Yes to continue
Analysis")
End Sub
