I have a program using the OleDbCommand to read an indexed Access database. [code]I notice that when step debugging the program, the file is not being read in correct order.Example: it will read the record with "B" in the D01 field before a record with "A" in the same field.The record with "B" is the second record in the database.I do note that all records in the database are read before exiting the loop, just not in any apparent order.

So I've been using VS2010 and haven't had too many problems transitioning over but I have an issue at the moment and I can't seem to find the answer...I have been using a little piece of code to insert comma delimited files to a database, which works great.Today, I received a Tab Delimited file from a client....obv I could edit, replace tabs with commas and move on but I want to know the right way to do this so I feel accomplished I've tried two ways so far1. This is the code I use for comma delimited with a slight change for the tabs -- PF refers to a class module that has the functions I use to get files and parse file paths

I am currently working on a vb project. What I am trying to do is reading a XML file and saving all the data in to the Access DB. Once this is done, I read the data from the access Db and display it in the required fields in VB form. Issue is, when i store the value in the access, a weird character is assigned before and after the data. The character is a square box with question mark in it. Also the same character displays on the VB form as well

I'm trying to build an app that will read custom properties set in an accdb file. Basically, I'm trying to build a Front End updater (Yes I know there are others already built, but they don't work the way I want). The Custom properties are initially set manually by pressing the Office button, going to Manage, then Database Properties and selecting the Custom tab.
I've got most of the code set up, but my sticking point is how to read the custom properties.
Following is the function I use within Access VBA to get the properties, but obviously this is not going to work in VB.Net.

I think I need to replace one or more of the 4 lines after the On Error (yes I know I need to change the Error trapping too). I'm guessing I need to connect to the database file (an accdb, btw) and then go from there to define the container and documents collections.

Actually my text file is a dump file and i need to make a program to process this dump file.

I have been trying to create a login page for a while and most of that time I have been searching for info on how to make it read the username, password and any other information off of a database.
I recently gave up and decided to use some code which reads it from a .txt file and this works and therefore I could complete the rest of the page and test it using the .txt file. However, a .txt file is not an ideal place to store the information as it is difficult to look at the text and find what you need to change if you want to upgrade the system to hold more data than before so therefore I came to this site to seek help on making the login page work with a database.
We have a site that is public facing, let's say it's [URL]. When the SSL is implemented, [URL], I can no longer access the jQuery 1.4.3 file on my own server. Furthermore, after a tweak to the security setting, I was able to get past the 'Access is Denied' error, but the first call was null. I understand there is a problem with different protocols actually being within the scope of the cross-domain problem? Is that true? And if so, will this now require JSONP?

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I have the following code where I make an copy of my database that I use. the code executes 100% but the problem I have is I'm not able to access my database afterward.I get a "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." and so if I restart the application it all works fine again.I'm certain the reason is because I can only access that database using a specific account name and password which is not account I'm logged in with.What i want to try is to default that database mdb to the point where no user is accessing it, or to reassign the the only account name that can access it to that database mdb. I've tried playing around with file security but had no luck.

I recently made a small exe program that connects to an Access database.Now it runs fine on most computers, but the one it HAS to run good on has some pretty harsh restrictions set on it's network.The problem is an OLEdb connection is refused because the file is not trusted on the Network, and I don't know how to give it the access it needs.I've tried running an install with it, and that will give it access, but only on the local computer and not on the network drives.I've tried placing the database in the network drive and accessing it with the install there, but there is a problem in that the local drives are wiped at logout.I've tried giving it trust access through Administrator Tools, but it always throws an error when I try it.
