Saving Values In Textbox-es (VB Express 2008)
Sep 23, 2009
I have a simple windows form application (I'm working in Visual Basic Express 2008).
There are some forms that have simple text boxes. When somebody wants to edit something in this boxes he pushes edit button and then they are enabled. I insert some text and when I save this text is saved for good.
When I reopen the application this text is there like I want it to be. Just for information, this text is always the same in one text box, until I change it (me or some other user) - so I think there is no need for databases. For my needs this is ok because I don't need to change this data often. This is code in Form load event (for calling back the data)

My windows form as a bunch of textboxes on it that basically let the user put in different positions/forces that a test cycle then uses. I am trying to let the user save their profile settings/open the settings so they don't have to input the same values every time they want to run the same test. Here is my code so far. basically, when i save my csv file, and open it, all 6 textbox values are plopped in the first textbox instead of being distributed to their original boxes. I just read about a "split" function
code
Private Sub SaveProfileToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveProfileToolStripMenuItem.Click
SaveProfileDialog.ShowDialog()
Dim sw As StreamWriter

I have added a new column to my bound datagrid table using sql server management. Added a new textbox to my form and using databinding, bound the textbox to the new column. Running my app I can enter text in the new textbox and if I save or move from the current row the text shows in the grid. But...after refreshing the grid or restarting the application, the text is no longer there.

The problem is this: I have two forms. One form and the other form do mathematical calculations. I want to save the values that the user inputs, so when the user quits the program and then starts it up again the values are still there. But when I open up the program, start typing in values, then calculate them, hit quit. Try to open up the program again, its giving me a message that the input file is invalid. When I click ok, the program doesn't crash, continues. But the values are not there at all. The other form I put exactly the same code, just changed the variables and it doesn't want to save the values at all! I wrote this code for saving and loading the values:

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

Whenever I modify a file in the IDE in Visual Basic Express 2008, and then press the "Save" or "Save All" button, the "Save As" dialog opens, then says that a file of that name already exists and requests confirmation of the save. This didn't happen in Express 2005 as far as I remember.

I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

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

It was coded by dragging the things from the dataset as a datagrid onto the form. It is not coding I worked out, in case more needs to be added to the coding

I am writing a code to search through the entire listbox items and highlight them whenever user enters text in textbox. I am looping through textbox items which are entered using a 'comma' . But the code fails to add it to selected indices when user types multiple items using comma. It works fine for single items.

If (e.KeyCode = Keys.Enter) Then

I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
