I'm trying to figure out how to do this as I'm not sure what's the proper way of doing this.
I've got several strings that I want to store/save permanently, even after the application is closed. How should I proceed? Do I read or write from a textfile?
I need to permanently store a string or maybe a object in my application. And yes, I have tried the application settings (My.Settings).
My.Settings.something = "hi" will save "hi" into something, and when i use msgbox to output the data, it works. The thing is; when I copy my application to somewhere else on my computer it is gone. I guess the settings is saved to some file at the filesystem, and when I move my file it also creates a new settings file. How can I store a string inside my application, and also move the application later on?

When I put information into my database form, the data is not permanently saved to my database?
View 1 Replies1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."

View 10 Repliesfor example i have this code :
Sub Month()
Dim Conn As New Data.OracleClient.OracleConnection
Conn.Open()
Try
Dim Cmd As New Data.OracleClient.OracleCommand
With Cmd

What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?

View 3 RepliesWhich is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.
View 1 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

I am making a video conversion tool. I have a listview with one item per file.And i also have options to add subtitles to movies. I want it to be like this:Say the user add 2 movies. He select the first movie in the listview and then go to the subtitle tab beside. There he checks a checkbox so he can add subtitles. Some controls comes up that allows he to browse for subtitle and select which language the subtitle is. Then when he has selected these options, he select the other movie, the program saves the subtitle data somewhere and then erases all fields so he can fill them with a subtitle for the other movie.

for an example I'm making an RPG game for learning purposes and I have several modules, each for storing different data (one for items, one for enemies etc).I'm storing each item or enemy in a structure in the module so it's easy to find and obtain the values and makes it easier to add more when needed. I'm sure there's a easier way because at the moment I'm storing it like this:
