Whenever I change a user setting in app.config (via running the program) the change doesn't appear in the app.config file (it stays the same). When re-running the program, however, the change is reflected in the program's behaviour. How can this happen if app.config wasn't altered when the program was last run?

I made a program which uses sample.dll. The program communicates with this .dll and does various tasks. Now, lets say I developed a new dll (an update, pretty much). Can I just give my users a new copy of the .dll or do I have to re-reference it in my project and then compile my programs all over and then give them a new copy of the entire program?

I have an issue with a data table that I have updated using the datatable.update command.The datatable is bound to the datagridview using dgv.datasource = datatable.I have used INSERT and UPDATE commands and the INSERT command writes the data back to the database ok. However my problem is that it the dgv is not updated with the primary key (ID field) from the database. So when I save a second time, instead of updating it just inserts the data again.
[Code]...
I have run into a problem with saving to database when running the program I am making.
I have an mdf file called prices.mdf and have set the "copy to output directory" to copy if newer setting and set this for the ldf file build action is set to content.. should it be compile or a different setting??
I access this database thru a dataset called pricelist dataset and when the program runs and you go to forms to update the prices, each form has a datagrid with the toolbar and the save icon. Mostly I followed tutorials to help me put it together.
When you run the change price menu for each part of the database, they appear to save each time u re run the program. But once you close down vb2010 and reopen it a day or so later and rerun, the new prices are gone and the old prices are being used.
I thought changing the setting on the mdf file to copy if newer is the usual fix for this, but as I said I have already got it set to copy if newer.
I can't figure out how to track what the dataset is accessing to make sure it is going to that database, or if i have made some sort of other database that it is accessing instead as well as the mdf database.
when I look at the dataset and the column entries for each part of the prices database, as to whether i need to check the dataset itself, or the forms the datagrids are on with the toolbar save icon, or whether there is another place to check to see if it needs to be changed to something like change if newer.
Obviously the program is working and doing the changes, but not storing them in the right place, so I am losing the changes once i shut down my project and reopen it.
also I have looked at the file propertiesand made sure they all set to copy if newer PricelistDataSet.xsd, pricelistdataset.designer.vb, and also the pricelist dataset.vb, xcs and xss ones are all set to copy if newer when I look in the solution explorer.butsome of the build part is set to compile on some and none for others As I am not experienced with VB 2010 or databases I am not sure how to track it down
Update: Just looked under each of the forms the data grids are on. and see the copy to output directorys on these are set to do not copy for each of the designer.vb, vb and resx. I am bit hesitant to change these without getting some advice from more experienced people if the forms also need to be set up to copy if newer.
This is what is shown in the coding on one of the forms if u double click on the save icon in toolbar

View 1 RepliesI want to save a datatable to the app.config file (My.Settings) and what i have understand is that you can use the Datatable.WriteXML to convert it to XML and then save that string to the settings.

Im trying to make a program that works a bit like the log in on a computer. But i cant make it load a different .config file depending on what username is used.

View 16 RepliesI have a program with the connection string to my database in the config , this file is in the main directory where the software is installed. My question is: Other people can edit or replace this config file with other for example to connect my program to his database? or edit other settings in the config ? so my program will work with a edited or replaced config file?
View 9 RepliesAfter reading through a bunch of stuff, I was curious what production developers use for config files. I know that there is an app.config file that can be modified by the user of the program w/ settings. I also know I can create my own .xml file or .ini file to store settings as well. I wanted to know from the production side, what do you use and why?

View 2 RepliesHow do you write config files for vb programs? Like .xml files, Seen some examples but didn't fully grasp them.

how to load the settings from these configs. The reason I want to write it to an external config is because I plan to add an updating feature and I want the configs outside of the program.
Is there a really simple way to save the app.config file to a location then load it again? I'm making a multiclient app. I was planning on having each user have a folder, and in that folder would be their personalized app.config file that would load when they log in. I don't really know any XML.

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:
[Code]...
pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.
Our main application has both a asp.net and winforms component. There is a class that is used by both sides and needs info from either the web.config or app.config files. The class itself does not know if it's on the client side or on the web server (at this point). We are getting errors when it's attempting read app.config when it's on the web side. Is there a way for the class to tell if it needs to read web.config or app.config?

The table is not getting updated.
I'm trying to write my first application which connects to an Access db. It took me hours to understand this, but I figured out that, if during the creation of the connection I chose to copy the mdb file in my project directory (VB asks this), I get that the database is not updated. Everything works, except the save button which saves new rows in the db. If I answer no, and the original mdb file is used, the database is correctly updated as expected. Is there a reason for this? Why is this happening? Shouldn't the database bu updated anyway?
