In Visual Basic 2010 Express, I would like to open an existing excel workbook. Then I would like to retrieve some data from the workbook to use in a calculation.
Is Visual Basic 2010 Express capable of this? All of the examples I have tried to work from have been from older versions and they have failed.
I am trying to retrieve the data from EXCEL 2003 spreadsheet from row 8 onwards because from Row 1 to Row 7 the row is merged columns from A1 to K1, A2 to K2, A3 to K3, A4 to K4, A5 to K5, A6 to K6, A7 to K7.
View 28 RepliesI 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 created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.
View 14 RepliesI have a problem with importing an excel into a data grid.
Here is my code:
Try
Dim _Obj As New ExcelConnection.ExcelConnection
_Obj.ImportAttendence("c:Info_pc.xls", DataGrid1)
Catch ex As Exception
End Try
In the excel i have numers and text and "Service Pack", "Processor Speed" and "Numar procesoare(Number of processors)" and the values for these are numers. in the data grid when i import the excel those values doesn't appear, i receive the value "null".
I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
I typed this question once already, hit preview, and somehow never got the preview and lost what I typed. It has been that kind of a day.So here is my quick overview then I am going shopping. I am using OLE DB to select from an excel spreadsheet. It has over 15000 rows and 33 columns. Sometimes even when a cell is not null, it is returning a null value. If I just do a "select * where [termination date] is not null", for example, it will return no rows even though I can see with my own eyes that sometimes termination date is not null.

I was using ContentType="application/vnd.ms-excel" on my web site to display a datatable in an excel workbook on the client. It worked great. Now that I have upgraded to Office 2007 and vb.net 2010, I get a warning saying that the file is in a different format than specified by the file extension (.xls). I googled new ways of exporting data to excel, but have yet to find a good example. I usedMicrosoft.Office.Interop.Excel which worked great, except I read that you are not supposed to use this on a web server.

View 9 RepliesI need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application
[Code].....
The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.
where X, Y, Z, F1, F2, F3 can be as small as 1 digit or as large as 3. There is a space between each value.I need a loop where I can write these digits to an excel document where:The first X goes into A2, the first Y goes into B2, the first Z goes into C2...The second X goes into A3, the second Y goes into B3, the second Z goes into C3...And this continues for as long as the program is run.
