Can't Display Data In Textbox From Database
May 4, 2012
I'm creating a project for my brother's thesis for his VB subject.Now, the thing is, I'm trying to display row data from database to the (already binded) textboxes in form1. As you may know, this procedure requires that the program:
1. Declares an sqldatareader, sqlcommand, and an sqlconnection.
2. open the sqlconnection.
3. ....and use the sqldatareader to fetch the data from the source file.
The database file is made using sql server compact 3.5 and is located on same pc as where I'm making the program.The problem is, I'm getting stumped in trying to connect to the sql server. I'm getting a 26 error "error locating server/instance specified". installing sql server 2008 management studio to allow remote connections (which was already allowed in the 1st place), enabling TCP/named pipes protocol in the config manager, and enabling sql server browser service. I dont have spi firewall on since my isp has its own firewall on and xp fwall is off too. What I'm not sure about is my connection string as it might have been impeding me to connnect to server. How do I form out the correct connect string?

I been google search for a while (a month at least). My problem before is how to read raw data from access. however, i find out that access not suitable for my project. I more interested in using Excel, because for later analysis i would came out with graph using excel rather than using access. Since, i been develop a GUI Program for Battery Cyclic Test. The part for Cyclic Test and DAQ Interfacing is done already.
My weakness is not been able to understand/know how to read raw data for particular column, and display it into textbox. In many out there forums or discussion, they explain about this kind of database by using class in VB. But, i would like to implement excel data manipulation in VB-Window Form Application.[code]...

All I am trying to do is create a form with a Textbox and this should display the data received from the serial port.
The data i am trying to receive is "ABC" on Com1 Can anyone either send me a project, as I am sure its something to do with how i am configuring it, or if thats not possible, show me in code?

I currently have a SQL Server database with a number of terms along with their definitions and the textbook chapter in additional columns of the database.In my application,I have a listbox which displays the terms; however, I wanted to allow the user to specify a lowerbound and upperbound for the chapters and the application would only display the terms between those two chapters. For example, the user inputs chapter 2 and chapter 5 and the application displays in the listbox all terms that are from chapters 2-5 inclusive.
