View 2 RepliesI am quite new to visual basic and databases. Im connecting to the database using the dataset wizard in visualbasic 2008. And then dragging each text field on to the form. Everything works well, saves etc., updates ok. Until I have a multiline text box , when I try and save, Iget errors highlighting the table update code and get an error saying it cant be converted to a string. I have changed all the max text limit on the database so its not that. It works ok if I set the textbox back to a single line mode. Does these databases support multiline textboxes?

View 2 RepliesI am currently puting together a data driven application just for fun and to get to know sql. The problem i am having is on my new customer form I cannot get the data in my text boxes to save into my database table at runtime. I simply have 4 textboxes and a save button the code for my save button is as follows:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim Connection As SqlConnection = MSDB.GetConnection
Dim mySqlCommand As SqlCommand = New SqlCommand
Connection.Open()
[Code] ....
All this does is bring up an error in runtime. How to get that to work when I press save the details in my text boxes are actually saved into my database table.

then send it to datagridview
I've the data in Datagridview (2 column - wavelength, absorbance) and i need to display in text box based on some reference. let say my first reference (soot it has wavelength value plus minus 2000 (range 1998 until 2002), 2nd ref NO2 plus minus 1630 (range 1628 until 1632) and others ref.
Firstly the system will find the specified wavelength in column1 (datagridview). if wavelength(column1) found in that range it will display the value in the textbox (column2- absorbance). then the information in the textbox, need to be save in oracle.
tell me a way that i can save the stuff written in 3 text box (Name,Address,Bday) by using a command btn. And then finding all of their information by just entering Name using another button.
any help would be grateful.
please and thank u

View 4 Replies(I used to use VB6.) I have been developing a database management program which is quite simple so far, with navigational controls, ability to delete record, datagrid, etc.
It uses databound textboxes, but when I modify the content of them it does not update the database. Same applies when I add a new record and fill in the textboxes.
I have been searching for the past hour to try and find a solution, but I have been unsuccessful. Also, I use VB 2008, so the Common Dialog Suggestion would not work.

I have a datagrid bound to a datatable. The datatable will then be written to an xml file using the built in "WriteXML" function, which is sweet!
What I would like to do is update the table then overrite the existing XMl file when a cell value changes.
The problem is the "CellValueChanged" event is fired before changes are actually committed to the dataset. I do not want to use the "CellValidated" event because it will fire for each row when the file is forst loaded into the dataset and displayed in the datagrid.
I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?
View 3 RepliesI have a main form (Form 1) with a menu strip and navigation bar. I use the main form to launch other forms (Form 2) as children of the main form.
All of the children forms contain SQL data sets /grids. I would like (if possible) to use the save button on the main form, to save data changes of the children form to the SQL database.
I'm working on a simple "sports management" game just to test out whether I could make an actual one some time in the future, but for the life of me I haven't been able to figure out how to save the contents of the datagridview. I want it to be saved in a format that doesn't require the user to have Access or any other program, so that the only thing users need are the .exe and the database file. Another question about the datagridview: How do I access the content on specific rows and columns of the datagridview? If I want TextBox1.Text to be whatever is written on Row 4, Column 2, how do I access that information?
View 1 RepliesI am trying to copy a table from a network database to a local database. I used DAO and could check if the network table existed using a function that tried to assign a TableDef object to the table in question. If there was no error then I assumed that the table existed and the function returned true...Or it would error out and return false.I could then proceed with the copy or not as the case may be.I am converting the code to ADO.net and need to know how to check for a table.
