Im trying to add an export import method in visual basic. Export from Access database to Excel Worksheet or .csv. And Import From Excel worksheet or .csv to Access database
View 3 RepliesI have to write an application in Visual Basic.Net that will open an excel file, run through the contents an export a test file for processing.
The application works great for me (Windows 7) but when transferred to a WinXP PC gives the following error: HResult 0X800A03EC
I can replicate this error by making the Excel Application visible so it seems like it is an issue where it can't access the file because it is open. Error occurrs when trying open the workbook.
Original Code
Dim excel As Excel.Application
Dim wb As Excel.Workbook

I have to import a tab delimited file into Excel and export it back out to correct a formatting issue caused by FoxPro. I need to pad a column with 10, Zeros and that is good with this here: objxl.columns("B:B").numberformat="0000000000". However I have 2 cells in the sheet, row 1B and 2B that I want to exclude from the number format above. Because it is a date field and it writes to that same column so it pads my date. I do have a need to Pad that date field with mmddyyyy so I have to pad it 8 - zeros.

View 1 RepliesI am trying to read off some cells from an Excel File. I can't figure it out. Here is my code:
Public
Class TOC
Dim ExcelObj As New Microsoft.Office.Interop.Excel.Application
[Code]....
After making WorkSheetObj I dont know what to do.. I am trying to dynamically change the Texts of Four buttons. The text values are to be to read off of Excel cells.
The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.
