File I/O And Registry :: Save Information Into A Text File From Runtime VB2005?
Jul 24, 2009how to save information into a text file from runtime VB2005. However, I wish to be able to write the information into any kind of form of file that cannot be simply opened and read by anyone (such as text file can be). Is there anyway that VB2005 can do this?

VB2005 :: Save Data To User.config That Is Not Bound?
Sep 18, 2009I have done a fair amount (days)of searching, before posting this,and cannot seem to find an answer.ata put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings
View 3 RepliesPublished Program Doesn't Include Text File And Database It Needs To Run
May 11, 2009When I publish my program I get no errors, and then when I install it on another machine it says it gives me the error that it can't read the txt file that it stores data in. If I hit continue it also fails to read the database. The database file is stored in the bin/debug folder and I told my program to include it when I first added the data connection. Anything I can do to have these included so my program can run on other machines?
View 6 RepliesSql Filestream - Update A File And Save Changed File Back To Database
Oct 30, 2009I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

Mar 8, 2011I am on a general scenario of deploying my vb.net database application on my client's computer.
Thinking of future problem of changing the database connection setting, i am planning to store it in a normal xml file in the app directory so that where ever it is installed, in order to make database configuration i only need to make change to that file and my program runs smoothly.
So is this idea of storing database connection setting to xml config file in app directory or is there any other better idea?

Dec 17, 2009I'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.
