Im looking to set up a VB.Net application that allows me automatically import files from Excel into an Access Database. Can anyone point me in the right direction? I will be importing files regularly so I would like to make an application to simplify the process. Would I be better off creating a Macro that I can reuse in Access or a VBA or?

I have written a VBA code in EXCEL that updates my tables in Access. The code is fully functionnal when I am entering new data but I don't know how to make it work when a data (primary key) already exists and that I need this data for another table. I would like to find a code in this format (DAO) :
If value exists in table Then
Return the value.code (not the value but the code related to this value)
else
.addnew
here is what I have tried but does not work:
Code:
Function Find_Last_EngineCode() As Integer
Dim cn_engine As ADODB.Connection, rs_engine As ADODB.Recordset, feuille As Worksheet, plage As Range, last_record As Integer
Set feuille = Application.ThisWorkbook.Worksheets("To_Access")

I currently have a bunch of numbers separated by tabs saved in a text file. Is there an easy way to copy the information from that file into .xls file and add additional information (like row and column names). I need the information to be in a report format. I am not sure the best way to go about doing this.

My company is making thousands of products now, every one of them have several test report in excel files. I am thinking about putting all of them into a microsoft sql database,
1. Is it wise to do so? I think a sql database is a lot easier to manage.
2. Can I save or convert the excel file as one data in a table? How could I do it? I only see a image type for data type. Surely I expect to retrieve the excel file through ASP.Net website if necessary.oh, some additional info, every excel file is not big, but it contains pictures inside sometimes.

I am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
reader = New IO.StreamReader(fname)
Do While reader.Peek() >= 0
linesread = linesread + 1

View 2 RepliesI 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.

I have create Office Excel application in my machine(XP). and i have placed the application in windows server 2008 giving the following error.
Microsoft Office Excel cannot access the file 'serverInput.xls'. There are several possible reasons:
The file name or path does not exist.The file is being used by another program.The workbook you are trying to save has the same name as a currently open workbook.

created assembly for the application and calling the code from the form.
I'm trying to use a combo box to change the image in a picture box to one that's stored in an external folder. The plan is to, in code, take the part of the file's location that will be constant and concatenate the file name to the end. The file name is stored in a database.

These are two code blocks from the two programs I have wrote. The first is the server program that receives a connection and writes the file to disk. The second is the Client program that sends the file to the server to be written to disk.As it is - it hangs. I did once get it to write to the disk - but the file was twice the size of the original. what objects to use for transferring a file over a TCP IP network connection with TCPClient and TCPListener.
I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
