Sep 6, 2010how do you save data stored in an array of records (structure) to a text file using StreamWriter? I currently have
Private Sub btnSaveToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveToFile.Click
Dim sw As New StreamWriter(New FileStream("EmployeeDetails.txt", FileMode.Create, FileAccess.Write))
For Each record As EmployeeType In employees
[code]....
but it doesn't work. My array is fixed and currently has 3 elements (for testing purposes). If I enter two records and add these to the structure I get the following data saved to the text file:
123,helen,66000
879,john,89975
0,,0
How do I stop unused elements of the array being included when writing to file? Should I use a dynamic array instead and if yes, how do you use dynamic arrays with structures?

2010 - Cannot Save/Pull Data To Access Database
Mar 21, 2011I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.

Unable To Save Data From Datagrid To Access Database?
Dec 7, 2009I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.

I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

View 5 RepliesMS Access Slow In Network Share
Dec 26, 2011I have a .NET application (VB.NET) that runs against a MS Access database. Every data request connects to the access database, runs and returns the query and closes the connection back again. I placed the database on a windows xp 32-bit machine. I have two clients on which I installed the .NET application. Both clients are running windows 7 professional 32-bit. Now I have a performance problem with this.
When I use the first client it runs fine. All data is shown very fast. When I than use the second client, it takes some 10 seconds to connect to the database, fetch the data and close the database connection. When i ask for other data on that second client, it all runs fine, until I request data from the first client than back again. Than it takes again 10 seconds on the first client before my data is fetched.

MS Access Table Update Extremely Slow?
Apr 6, 2009I have looked all over for a solution to this problem and have tried a bunch of different things, but nothing seems to work.I have a sub procedure that does the following:
1) adds two columns to a data table (table1)
2) fills a dataset with several tables in order to make calculations (this determines the data that will be stored in the two new columns of table1)
3) updates ONLY table1, and ONLY the two columns that have just been added (these columns are thus empty for every row before the update begins)
As it is now, the da.Update takes about 3 hours to populate the entire table (it updates about 300 records per MINUTE if I'm lucky). There are approximately 40000 records in table1 for this test subset, but there will eventually be up to 1.5-2 million (in other words, this is a small table currently). I have tried using executenonquery() along with a sql UPDATE command instead of da.Update, as well as many other things, but none of them has improved performance at all. I've also tested it on two PCs, one running Vista and one XP, and there were no differences. I'm using Access 2003. I know Access is not ideal, but for now it is the only option.
I know that the root of this is the line of code with the da.Update, because the giant loop before it that I previously thought was causing the slowdown executes in 30 seconds, leaving only the update before the subroutine is complete. I don't know how exactly the da.Update works, but I've suspected that maybe it has something to do with that? Code is below:

VS 2005 Slow Performance With Backend Ms Access?
Apr 2, 2009I have built an application using VB 2005 express edition with backend Ms Access 2000. In main form(which is loaded on startup), I am having 9 datagridviews, each bound with databindingsources. I am refreshing this data every 15 seconds by refilling the table adapters and updating the datagridviews.Now, this access database is shared in the network and is accessed by about 5-6 users concurrently. There are other forms which are used to edit the data.My problem is poor performance of the application. Its very slow in opening up forms, not responding sometimes and using the network resources fully.
View 5 RepliesApplication Slow Is DB Access/text File Code Ok?
Jan 26, 2012I noticed that my application is running a bit slow. This is a Windows Service built using VB2010 with SQL Server as a back end. Its main function is to poll a folder looking for a text file. If found it reads the text file and imports the data into SQL Server.
While the slowness could be caused by a number of reasons, I am looking at my code to determine if it could be more efficient. Below I've pasted snippets of code where I initialize the DB connection and execute SQL statements. I've also included a snippet that illustrates how I am processing the text file.
I'd appreciate if the group could have a look at these and let me know if the method that I am using is the most efficient possible. At this time I am also focusing on other probable issues, but I can't rule out the possibility that the code that is in place might be a contributing factor.
