I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.

i want 2 select data from data gridview and want retrive that data into another form in to the textbox ...is it possible ? i 'm doing like this for that

i have a program called Vip Task Manager.This program lets me set up task which others have to complete.When they are done with a task they have to mark it "completed" and make a report on what they have done and used to perform this task.Vip Task Manager has a button which directs them to an upload form, now when they press the "open" button I would like this to happen: Open a certain report making program I made myself.When they finished writing their report and press save, the program saves this report on a dedicated network HDD (.txt file) and closes itself.Then add the file or link to the upload form in Vip Task Manager.What it all comes down to is that they dont have to minimize Vip task manager, open the report making software, save it, go to vip task manager, press upload, press open, look where this file is saved, select it, and upload it.now, typed in red is whats already been taken care of.The rest, I have no idea where to begin to be honest.First I want to find out how to retrieve that a button is pressed in a existing program. (dont know which code it is written in and it is not open source)

View 5 RepliesI am retrieving data from a csv/txt file using oledb driver
ConnString = "Provider=Microsoft.Jet.OleDb.4.0; Data Source = " & System.IO.Path.GetDirectoryName(strFileName) & "; Extended Properties = ""Text;HDR=YES;FMT=Delimited"""
strQuery = "SELECT * FROM [" & System.IO.Path.GetFileName(strFileName) & "]"
In the last line I am getting following error if the filename is large
