View 4 RepliesOpen A File And Change Stuff, Then Close It Without Saving The Changes, The Events Still Fire?
Mar 17, 2010I am using about 5 different filesystemwatcher routines total. I am using the following
filewatch.NotifyFilter = NotifyFilters.CreationTime Or NotifyFilters.LastWrite
AddHandler filewatch.Created, AddressOf addfile
AddHandler filewatch.Changed, AddressOf addfile
filewatch.EnableRaisingEvents = True
However, there is one problem with it... whenever I open a file and change stuff, then close it without saving the changes, the events still fire. I am opening excel workbooks in code, then use xlsWB.Close(SaveChanges:=False) to close them, and the event still fires, where the file isn't really changed so it should not fire.

Saving Changes Made In A Program Into The Access Database
Oct 7, 2009I've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
Here are some relevant pieces of code:
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\InventoryMusic.mdb")

Not A Valid Update Method In Datatableadaptor - Saving Access Database?
Jul 4, 2009I'm struggling to work with data in VB 2008, and find it extremely complicated! At first I couldn't even get a database to load, as VB 2008 kept complaining it was created with an older Jet engine.OK, I converted it to a newer Access format that VB 2008 finally accepted.
In trying to find out why changes weren't saved, I found a common problem was VB 2008 wiping out changes.OK I have told the compiler not to copy the older database file back over but to copy newer.Updates then supposedly happened --- no errors were reported --- but the changes were still not saved.It appears the update method didn't exist in the datatableadapter, but I got no error messages about that.
No update done.
I've used the tools to configure the dataset and datatableadapter.Automatic generation of methods like update, add new, delete, etc. were supposedly done.Now, when trapping the error, I'm told the update method isn't a valid one.I found little information on that. It suggested primary keys could be a cause, but adding or deleting a primary key has no effect.I can see the fill method, and it works fine.I can't see the update method. (Apparently it is in SQL which I don't know anyway.)

Windows - Records Added To Ms Access Database With Vb 2010 Not Saving?
Mar 18, 2012I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:

Database Primary Key Won't Hide And Some Other Stuff?
Aug 17, 2011So Im making a program with 2 different data tables where different columns from those tables are used in different tabs in the same form. This all works good and well so far, but I have one issue which just drives me mad, and a couple minor ones.
1. I have an ID column in each data table marked as Primary Key, Unique and Identity. Problem is that even if I choose to hide this column it just randomly decides if it actually is visible or not. Most often its visible. I dont get it, doesnt this function work? Do I use it wrong? Im not using any code for this, just right click on the data grid, press Edit Columns... And change the Visible to False. It works for all other columns all the time as far as I can tell, but for my ID column its just random.
2. Im wondering if its possible to align the text in some of the columns of my data table to the right, note I only want some of them, not all of them.
3. Is it possible to do maths with the values from the columns in a table on the same row? Like for example having column 3 = column1 + column2?
DB/Reporting :: Database Can Only Add Stuff, Not Replace Or Clear?
May 29, 2010I'm quite new to databases so this might be a very basic question: How does one replace a table in a local MS Access database with a new dataset?
I'm able to read the contents from the database into the dataset DatabaseDataset, change it so it looks perfect, but when I update the Access database, it only adds the dataset instead of replacing the existing contents. I tried to clear the contents of the database, but that doesn't work either.

VS 2008 - Sqlserver Database - Tables And Stuff Just Vanish ?
Jul 1, 2009I seem to have a major problem. when I add a typed dataset to my project and go back to my sql server and click on the databse I use it doesn't open. the tables and stuff just vanish. using the wizard, it creates this connectionstring:
<add name="Schenectady.My.MySettings.SISQL2ConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataSISQL3.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
It connects fine. but after I try opening it in sql server i get an error. It doesnt let me restore or anything. i tried restarting my pc incase the db was locked but it is still gone. now my app cant connect. Just for clarity, is user instance supposed to be set to true. and what is the purpose of it. also when the wizard asks to make a copy of the file that will be copied accross each time I run my project I select No.
