Using VB Import Multiple CSVs To Access Table, Verify, Remove CSVs From Folder?
Apr 9, 2010
i have a series of CSV files that are posted to a specific web folder that I can specify in network places. Each file has same structure, lots of fields, and have consistent name schema "prefix-mm-dd-yyyy.csv". i need to use VB to process all these files, either individually or by consolidating into one file and appending to an existing table. i also need to somehow add a "download date" field to the process so i can show when the file(s) were appended. then i need to verify that it worked ok so i can then, still within VB, move the files out of the folder, such only the CSV files that have yet to be imported/appended are in the folder (so I don't have to guess about which files I have already uploaded and processed.i can figure out how to make a DO UNTIL loop, but i can't get the import statement right... nor can i figure out how to verify that the import happened in order to move (or remove) the source files.
I have a very simple app (at the moment) that stores file names/paths and folder names/paths in an SQL database and displays them in a ListView and TreeView respectively. All fine and dandy.I have an option to remove a file or folder from the appropriate database table and then recreate the associated list.[code]I've checked and double checked the folder table adapter (even to the point of recreating it c/w Insert, Update and Delete commands) to no avail.
I am developing an application to give acess to a folder like read, write etc and also i need to remove access from the folder form a pirticular userI have given access to a folder using the following code
dInfo As New DirectoryInfo(CurrentPath) Dim dSecInfo As DirectorySecurity = dInfo.GetAccessControl(AccessControlSections.Access) Dim myRuleValue As Integer = 0
how to import the data in an excel 2007 file located on the local computer or on the network into an EXISTING Access 2007 table? The excel file contains a single sheet.
As part of a larger application, I need to IMPORT (not link) a FoxPro 2.6 DBF into a Access DB.I toyed with using a Access MODULE and in the module, using the docmd.TransferDatabase method.I have looked for days at different samples and I cannot seem to find the answer.This application is intended to be distributed with NO ASSURANCE the user will have the FoxPro OLE driver installed. Knowing that the ODBC driver will most likely be installed as part of MDAC, it is pretty safe to use the ODBC driver that is already installed - Visual FoxPro Tables
I'm using the following code to import data from a text file into an existing Access table:
Code: Imports System.Data.OleDb Public Class Carrega_CSV Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]....
The first time i ran the code, it caused no error but no records where loaded into the table. The second time it causes the OleDbException "Table 'TEMP' already exists." The text file is comma delimited and it has exactly the same number of columns of the TEMP table.
i'm trying to import a excel sheet to a access table but when I run.. it says: "The Table 'Telemoveis' already exists" and I don't want to change the name I just want to update the existing table ("Telemoveis") in the access

I am creating a MS Access database. The database will import a table from another Access database, query for selected data within a date range. Thus, I am having difficulty with the Macro code to import the initial table. Therefore, what's the code to import a table from another access database? The database is names InputContract.mdb.

I am considering a piece of code that will manage access to a collection object from multiple threads - add, update, remove, clear. OK ... so I have put a sync lock within each method, but what is not clear from the MS documentation is exactly how the sync lock is behaving. Is it locking the piece of code it wraps? Or is it locking the object? And if it is locking the object a private static object should lock out any code locked on the object within all instances of the object? i.e. if an add operation is underway, an update, delete or clear will wait for the lock to be released.
Finally, if I have multiple threads contending for the sync lock, how is the release managed? First come, first serve? random (from my p.o.v)? Is there a chance that two separate threads could blunder into 'locked' code simulataneously?
I am not sure how I would go about this I have a decision matrix that retains values which are boolean.The application receives a spec and rev from the database when the app is called.The questions asked as like " is it a car?" Yes/No etc.After the battery of questions I need to write the responses to an access database
Here is my db persistance class Imports System.Data.OleDb Public Class DBPersistance
I have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer intInput1 = CInt(txtInput1.Text) If intInput1 >= 3 or <= 7 Then messagebox.show("Input Verified") Else messagebox.show("Input must be a numeric value between 3 and 7") End If
I am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import() Dim db As Database Set db = CurrentDb
I want to write a program in vb2008 that can import a text file into a Access 2000 database, but using import specifications already in the access database.
I have software for STOCK and SALES that can give me an Excel price list, I wanna write a small web app that will enable users to check prices, I don't have any access to that software's database, so I wanna import that Excel data (one worksheet, 5 columns, almost 10000 rows) into an MS SQL database table, keep in mind that the price list will change few time a month so I need to re-import that price list once its been updated.

I'm fairly new to programming and have little to no experience with sql and file transfers. Here's what I'm trying to do: 1. Link my program to a database containing images (or pathnames to images) 2. Allow user to select a starting image and ending image (max 50) based on image numbers (which they already know) 3. Collect selected images from DB or could just be a copy of the image. 4. Export images to a new folder so that my other program can process and OCR them I have the form built, but I just can't figure this out.
