View 3 RepliesI'm using VB Express 2008 in Windows 7 64-bit. I'm working on a project with a datagridview bound to a MS Access 2007 database. I want to use the datagridview to add, delete and update the data in the MS Access database. When I added the database file to the project through the Datasource Configuration Wizard, I selected 'No' to copy the file to the project folder. The connection string automatically placed in the project settings is: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="F:My MoneyDoBillsDoBills2009.accdb"* The 'Copy to Output Directory" property for the DoBills2009DataSet.xsd is set to '*Do not copy*'(and I've tried every other setting available). So, as I understand it, I am working with the original file, not a copy, and any changes (additions, deletions, field changes, etc.) are made directly to the original file. I have added the following code to the datagridview rowleave event: [code]I'll figure out a way to skip the update if nothing is changed, but for right now, it doesn't work. I've searched MSDN, the MS Community forum and several other forums for a solution and all I have found is what I already have and it doesn't work.I can make changes at run-time alright, but the exception it triggered when I change rows, and the data is not saved to the database file.When I close/re-run the app, the changes to the data are not thereThere has to be a way to save changes to the datafile, but I'm just not finding it.

I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.

I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.

View 5 RepliesMy question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
