User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
could someone tell me what i am doing wrong in this codeProtected Sub insert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Insert.Click

I have a piece of code that takes two strings, puts them together, then attempts to save that result into a table in a database. For some reason, the database is only showing the second half of the string ( Me.txtRev.text in this case). When in debug, I can see that newRev is actually correct, with the hyphenated string.
