View 6 RepliesI've tried pretty much everything to solve this problem (except what works, obviously) and almost worn out Google, so now I'm giving this forum a chance. Basically I'm making an application which needs to map column names in an excel spreadsheet to fields in a table (TableB) through a data transfer setup table(TableA); To make this work as planned, I need to compare a value in "FromField" in TableA with headers/column names read from an excel spreadsheet into a list of strings, and if they match, map "FromField" against "ToField", prior to importing data from the spreadsheet. The column names that don't match with "FromField" are to populate a combo box in the FromField column in my DataGridView.
PROBLEM: I get this to work fine as long as I don't handle case differences (e.g. "FieldToBeImported" in Field1 vs. "fieldtobeimported" as header in spreadsheet), but this prevents matching words with case differences to be mapped, and leaves it to the user to manually map fields that should have been mapped automatically. However, if I make a ToUPPER copy of the List Of String that contains the MS Excel column names and compare them to a ToUpper version "FromField" data, I get the error message from the topic:
"System.ArgumentException: DataGridViewComboBoxCell value is not valid"A little explanation on DataGridView2 before diving into the code: Column in index 0 is a DataGridViewComboBoxColumn added in code, where matching fields in column 0 and 1 are mapped, and non-matching fields are populated in the combobox.Column in index 1 is "ToField" (TableA as source), Column in index 2 is "FromField" (TableA as source) and is hidden in runtime.

Quick question here about how to get it to accept capital and lowercase letters. I am running code that has certain Customer Types such as "T". It returns different information for that customer. There are only 3 types "T", "R", and "C". The rest return the default information. When I enter "t" into the textbox it returns the default information, not the information for "T". How do I go about getting it to accept "T" or "t"?

I have a fairly large project (Point of Sales) written in VB6. It has beenused successfully a 2 stores since 2001 (with updates of course).I would like to convert it to VB2008 (although I know about VB "fusion") just to keep it up to date and modernize it a bit.Since using the VB converter brings up such a lot of junk, I'm rewriting each module and form from scratch (although using as much of the original code as possible). One of the functions I'd like to retain is typing in a textbox, and converting each keystroke to upper case as it is typed.Here's the code I use in the VB6 version:
