Read Excel Data (Excel 2007 SP1, On Windows XP SP3) With .net 2008?
Oct 7, 2009I 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?

Office Automation :: Reading Cell In EXCEL 2007
May 23, 2011I've managed to work out how to read EXCEL cells via static values. Ideally I would like my application to check the third column of the EXCEL sheet and if there are no entries on a given row, it should display the coresponding row of colums 1 and 2...for example if (C,3) contains no entry then get values of (A,3) and (B,3)...then mark (C,3) as pending by writing a value to (C,3). Here is my code at the moment

View 1 RepliesVB 2008 Read From Excel 2007 Spreadsheet?
May 3, 2009I have an Excel 2007 spreadsheet with data about my golf group, e.g., each row has name, phone number, handicap, etc.I want to write a VB 2008 application to read each row, extract the appropriate column data, and then print it out. I can't find any help on how to do it.
For example, I thought I'd have to go to the references and add the Microsoft Excel 12.0 object, then import Microsoft.office.interop Once done, my thought on a simple line of code to just display the A1 box would be:
dim appExcel as New Excel.Application
dim variable as string
variable = appExcel.range ("a1").value
message.box(variable)
Running that results in an error exception. So I'm clueless. Any hints or pointers on what to do, especially how to contruct a loop to read the contents of each column in each row, process and move to the next row.

Dec 1, 2011I have a program that creates a excel spreadsheet and a chart on each tab from extracted data in various .txt files. Before the chart is created, two of the excel columns will end up with data like this: on column 9 and 10. I also use data (time, looks like 09:15) in column 11 that shows the time at the bottom of the chart. There are just too many digits in the output and the readability looks bad so I can also convert.
Input Output
800400047320000
825400047120000
[code]....
The chart will display those values just fine but, normally the conversion in code that I do during the placement of that data (so it reads a bit better) looks like this:
'Convert bit to Kbit
If InRate.Length < 7 Then
InRate = CDbl(InRate) / 1000 & " Kbit"
[code]....
how to make the chart work with just numbers and ignore the MB or Kbit at the end?

Apr 20, 2010I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

VS 2010 How To Excel Read/write
Jun 22, 2011I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".
