View 2 RepliesJust wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?
View 2 RepliesI have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
All I want to do is get a value from the database and display it via a message box.

I've been using Visual FoxPro for the past 10 years, and am trying to learn VB.NET, (using VS 2008). I am in the process of re-writing a small VFP app in VB.NET, and am using the VFP DBF tables, (via OleDb). It is a real struggle for me to comprehend all the levels to keep track of and was wondering in anyone knows of some sample code that would point me in the right direction. After I complete this small app re-write, I have others to do that all require the VFP DBF table updates.

I'm trying to connect and query a .dbf dBase table. I'm fairly certain I've got the connection string formatted properly, because I am no longer receiving errors that I can't locate the table.I've tried everything I can think of, and nothing seems to work to make a valid query. I've tried all sorts of syntax changes around the table name (which is just 'buildings'...nothing fancy). The error is a syntax error with an incomplete query on the executereader line.

Basically I need to create a form that will display a summary of the population trend for each species of butterfly from a database that I have.I will do this by having the user select which butterfly species he/she wants to view from a combo box and then the list box will display the count_2010 and count_2011 information for that butterfly species.
I have managed to link my combo box to the database but I am unable to get any information to be shown in my list box. I can use a select case and input text myself but I don't want to do that as in another form records need to be added. Is it possible to have the relevant fields from the access database show up in the list box after the user selects a species from the combo box?
