Read Raw Data From Excel And Display Value In Textbox?
May 19, 2012
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]...

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am trying to read excel data (Excel 2007 SP1, on Windows XP SP3) with visual basic .net 2008 (VB 9.0 SP1). I have tried several attempts and whatever I do I am getting the following error message: System.Runtime.InteropServices.COMException was unhandled ErrorCode=-2147319784 Message="Altes Format oder ungültige Typbibliothek. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))" Source="Microsoft.Office.Interop.Excel" Message="Altes Format oder ungültige Typbibliothek." Translated: Old format or unknown type libraryI have added the reference "Microsoft Excel 12.0 Object Library" to my project. I am assuming that I might have to add a different or an additional reference, but I do not have any clue which one to use. List of things I have already done:- Searched other forums- Altered the language settings- Tried it on an other Computer (Win XP SP3, Excel 2007, Visual Basic 2008 Express)- Ran the diagnostics tool in Excel - Updated all updates etc...- Reinstalled Visual BasicI really do not have any clue why it should not work?

I'm working on a project that incorporates an Arduino Duemilanove board and a program that a wrote in VB 2008. Basically, when the Arduino receives a symbol from COM3, it sets a Pin on the board, high or low. I'm using two Pins, one is going to be for a laser, the other a relay. The relay is going to close a circuit, and act as the button on the Nerf Vulcan. That's right, I'm creating a Nerf sentry gun.It's going to be fully controlled from my computer. I have all of the code done for the servo, and all of that, both on the Arduino and in VB.
The Arduino sends the angle of the Servo that will control the right and left movement of the gun through COM3, every time it changes. I want my program to display that position in a textbox, as my program needs that value in order to properly function. Basically, I need the code to read from the serial port, and display what it receives in a textbox, textbox3.

I'm creating a program and it is paramount to its functionality that it can open->read->close a Microsoft Excel (.xlsx) file.Now, I've searched the forums with the keyword "Excel" and found a lot of stuff in many programming languages, none of which were any use to me.
I should pinpoint that I'm not that good at programming as university takes all my times, but every summer (like this one) i really enjoy tackling my problems via programming.[code]...

I am trying to import and read data in from an Excel file that is being updated every half second by way of a DDE Link from RSLinx Gateway,which I think is a default setting, though that data only changes every few minutes. There are 5 rows and 8 columns of data that I am reading in.Each column is a different tester starting with the second row, Testers 1 through 7. The first column has titles that describe the data coming in from the DDE links.
Each column has 5 rows of data related to the tester.I know how to display the data which I will post my code for below, but as far as reading the data and determining whether or not the part was good or bad, based on a boolean value, I am stuck.I would also like to save the data into a different excel file after determining the status of the part so that we can look at past data.
Code display:
Imports System.IO
Imports System.Data.OleDb
Imports System.Drawing.Printing

I have an excel sheet that contains 25000 phone numbers listed in one cell with no sorting order. I want to create a small windows application that can read the sheet and return the total number of the phone numbers and how many duplicate numbers as well as the number of times of repetitions. How I can resolve this issue? What is the best way to approach it? I'm using VS 2008 and VB.Net.

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
