Transferring Latency Data To Excel Spread Sheet
Apr 5, 2009I have a psychology experiment that has users respond to specific text or pictures by pressing either a button for "similar" or a button for "opposite" and then the program records the time from the presentation of the stimuli to the time they press one of the buttons as the latency. I have the information ans some other data successfully exporting to a text document but would like to have just the latency data also go into an excel spreadsheet for easier analysis. Here is the code for one of my buttons that currently writes to the text document:

XL Spread Sheet To Array?
Jun 15, 2010I am in the process of converting VB6 in to Dot.Net 10. Phew. Fast way to learn a language
Currow value=24 in this instance
Arsheet2b = ObjExcelB.Sheets(1).Range("A2:L" & curRow).value
<error>
System.InvalidCastException was unhandled
Message=Unable to cast object of type 'System.Object[,]' to type 'System.String[]'.
</error>
I can restrict the sheet from A1:A24 (contains 2010) and I get the same error.
VB Spread Sheet Writing Lock
Jun 13, 2012at the moment I have a small application and need to take information from an object and display it into an excel file, using the Microsoft.office.interop class I've been able to write to the file, and it shows one by one the records being added, however about once every 3 times I try it, the spreadsheet stops filling somewhere between the 300th and 600th record, I have 6,000 in total and it's not breaking every time, I put a check after it finishes to see whether the last record is filled in but the code never reaches that point and I'm unsure of what's happening I also don't know how to debug the problem as it'd mean going through 6,000 loops to check for it stopping... which might not even happen?

I want to make a program in VB that makes calculations with the values in the A2 and B3 cell of the sheet. This is just an example though.
