stored procedure concepts in vb.net

can you be a bit more specific please?

Is this a question, a statement, or just a general thought ? I suspect if you wanted info on this, pasting it into google verbatim will give you plenty.

Hi, I am creating a front-end to the sqlite DBMS using VB.Net 2002. I have managed to get the name of the table, field names and types from user input displayed into a listview but I can only get the Create table command to accept the last input values, so if the table has more than one field(which nealry every table has) it simply ignores the previously entered fields.
How would I get it to create an SQL query with all the inputted field details?
I have inserted the code I have used so far.
Many thanks for your help.
This button opens up a new form for the user to input the field name and select the field type then brings them back and displays them in a listview.
Public Sub btnAddColumn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddColumn.Click
Dim frmAddColumns1 As New frmAddColumns()
frmAddColumns1.ShowDialog(Me)
fldName = frmAddColumns.ColumnNameTB.Text
fldAttribute = frmAddColumns.ColumnTypeTB.SelectedItem
'Create ListViewItem
Dim item1 As New ListViewItem(fldName, 0)
item1.SubItems.Add(fldAttribute)
'Add the items to the ListView.
listView1.Items.AddRange(New ListViewItem() {item1})
Me.Controls.Add(listView1)
End Sub
This button takes the input table name, field name and attributes and creates the SQL command to send to the database to create the table:
Private Sub btnCreateTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreateTable.Click
Dim tblName As String
tblName = txtTableName.Text.ToString()
If Len(txtTableName.Text) < 1 Then
MessageBox.Show("Please type a name for the table")
ElseIf Len(txtTableName.Text) > 0 Then
Try
dbConn.openExistingDatabse("Data Source=" & getDBName() & ";Version=3;New=False;Compress=True;")
dbConn.createSQLCommand()
dbConn.createTable("CREATE TABLE " & tblName & "(" & fldName & " " & fldAttribute & ")")
MessageBox.Show("Table created successfully")
Me.Close()
Dim frmInsertData1 As frmInsertData = New frmInsertData()
frmInsertData1.Show()
Catch es As Exception
MessageBox.Show(es.Message)
End Try
End If
End Sub

In btnAddColumn_Click() you assign fldName and fldAttribute and add them to the ListView but in btnCreateTable_Click() you don't iterate the ListView to retrieve all added columnnames and datatypes. You only use the las assigen values for fldName and fldAttribute.

Do you have Office 2003 installed on the machine that you're using Visual Studio with?
I recently went through an MSDN call regarding a problem with my application working with different versions of Office, and they said that you need to install the version of Office you want the application to work with on the development box to get the reference.
Hope this helps...

Hi,
Does anyone know any api that could replace hex character?I want to replace null character(00) into space character(20) when I import a text file into DataBase.Thanks.
|
|
|
|
|
What do you mean by "hex character"? Do you mean a character where you express the character code in hexadecimal?
Hexadecimal numbers are written using the &H notaion. The value 32, or hexadecimal 20, are written as &H20.
To create a character value from a numerical value, you use the Chr function.
If you put those togheter, you get Chr(&H20) to produce a space character.
Do you have problems with the replacing part? How about the Replace function?

LOL - when I saw &H20, I thought it said H2O, and that you were kidding....

if it does not work then your asp_net user do not have rights to use the word. go to control panel and in user accounts change the asp net user from limited to adminsitrator. Hopefully this will reolve your problem.
