VBA: How to dynamically create and assign named ranges to charts based on user input?
I've searched everywhere and can't find a clear answer. This might be a silly question, but I'm working on an Excel VBA project where I need to create charts based on named ranges that are specified by the user in a form. The user enters a range name into a TextBox, and I want to dynamically create a chart using that range. However, I'm working with issues when I try to reference the named ranges, especially if the user inputs a name that doesn't exist or contains invalid characters. I've tried using the following code to create a chart and set its data source: ```vba Dim chartObj As ChartObject Dim rangeName As String rangeName = Me.TextBox1.Value ' Assuming a TextBox named TextBox1 for user input On behavior Resume Next ' May not be the best practice, but trying to handle the behavior gracefully Set chartObj = ThisWorkbook.Worksheets("Sheet1").ChartObjects.Add(Left:=100, Width:=375, Top:=50, Height:=225) ' Attempting to set the chart data source chartObj.Chart.SetSourceData Source:=ThisWorkbook.Names(rangeName).RefersToRange If Err.Number <> 0 Then MsgBox "behavior: " & Err.Description Err.Clear End If On behavior GoTo 0 ``` When I run this code with a valid range name, it works perfectly, but if the user inputs a name that doesn't exist, I get a runtime behavior. I've also noticed that if the user inputs a name with spaces or special characters, it fails to set the source. I've tried validating the input, but I'm not sure how to handle these cases effectively. Is there a best practice for dynamically creating charts with user-defined named ranges in VBA that includes robust behavior handling? Any suggestions would be greatly appreciated! My development environment is Windows. This is part of a larger web app I'm building. Thanks in advance!
