The use of apostrophes in a textbox, when using collaboration with a SQL statement causes trouble - i was wondering if theres any way to get around this - ie when inserting a value that contains an apostrophe, to omit it before using the SQL insert statement. Any help would be greatly appreciated!

You can use StringVar=StringVar.Replace("'", "") to remove the apostrophe from your string (where StringVar is your variable). There may be something more elegant, but this has worked for me.

You may want to think about using a parameterized query to pass the values into your SQL statement. Using the SQL Server data provider, it would look something like this:
<br />
Dim sql As String = "INSERT INTO Test (lname) VALUES (@LastName);"<br />
Dim cn As New SqlConnection(cnString)<br />
Dim cmd As New SqlCommand(sql, cn)<br />
cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = Me.TextBox2.Text<br />
cn.Open()<br />
cmd.ExecuteNonQuery()<br />
cn.Close()<br />
Doing it this way will save you the trouble of replacing characters in each input field and will help protect against some forms of SQL Injection attacks. However, it won't get you out of validating input for other constraints such as length, etc.
Hope that helps!

If you're trying to insert into a database, just double-up the quotes, so :
INSERT INTO table VALUES 'O'Connor'
becomes
INSERT INTO table VALUES 'O''Connor'
have some functions to do this, or just use a replace. This approach has the advantage that the string is stored with the apostrophe in place

I'm trying to deploy an application and I'm getting an error that a newer version of a control is needed. Here are the details
1) My app uses an Access database and references 'ADODB', 'ADOR', 'System', 'System.Data', and a few other normal System references.
2) When I setup the Deployment Project, it appears that the references are correctly identified as dependencies (ADODB.dll, and Interop.ADOR.dll are both listed).
3) When I try to run my installer application on a different computer (w/o .NET installed, but after installing the .NET Framework), I get an error.
4) The specific error is: "The .Net Data OLE DB Provider (System.Data.OleDb) requires Microsoft Data Access Components (MDAC) version 2.6 or later. Version 2.53.6200.0 was found and currently installed)"
I did some research (by looking in references in VB6, since I couldn't find what I needed in .NET) and found the Microsoft Data Access Components is in odbcconf.dll. I tried including that as a file/assembly in my Development Project, but when I built the project, it gave me the following error: "WARNING: 'odbcconf.dll' should be excluded because its source file 'C:\WINNT\system32\odbcconf.dll' is under Windows System File Protection."
So, my question is, how do I get that file upgraded? Or maybe I'm looking at the wrong place? The funny thing is that, that very same DLL on my computer is version 2.52, and the project installs (using the 'Install' menu option under 'Project') and runs fine. The other thing I've tried to do is include the 'Database_Access.msn' merge module. That didn't work. BTW, all computers I've been working on/with are Win2000/SP3 machines.
I have searched the MS help, MSDN, and was searching other websites when I found this message board, so I apologize if the info is readily available somewhere on this website.
Paul
One more question... why does the Development project give an error about requiring the .NET Framework to be installed on the destination computer, but if I try to add the Merge Module associated with it, it gives me an error saying that it should be excluded?!

ElseIf optSuppOrder.Value = True Then
Load deMain
With deMain
.SupplierOrderAudit_Grouping txtUser.Text, CDate(Text5.Text), CDate(Text6.Text)
End With
SupplierOrderAudit.Refresh
If SupplierOrderAudit.Visible = False Then
SupplierOrderAudit.Show
End If
End If
if the above option button is chosen, the intended purpose is that the report is generated. However, occasionally, when the command button is pressed, it throws the above run time error pointing to the report line, why is this? any help would be greatly appreciated or if you need any additional info.

Just plucking at straws but the error may occur if deMain is already loaded (e.g. not unloaded properly from a previous report???).
Maybe you should look into creating a new instance of deMain each time you need a report....
If this isn't where you are receiving the errors thenignore my post

The error you mention generally occurrs when attempting to open an ADODB.Recordset object when it's already open - if you're reporting from a DB, this will prob be the cause, but suspect that it won't be in your code? Does that help?

dear all,
1) how do i trap the double click event on an item in a list view control (style = details)
2) how do i make Xp style tool tips (i.e. tool tip with cancel button in the top right corner)
thanx in adv

Q1) Isn't that with the DoubleClick event? and then you use the SelectedItems property to get the items that were selected, probably only 1 if it's a double click. If I'm wrong, sorry, I haven't messed with the List View control much yet.

Hi,
Is it possible to programatically access a Folder Properties...for example, A Folder can be shared on the network by right-clicking on it and going to the Sharing Tab. I want to be able to programmatically change/alter all options on the Sharing tab without right-clicking etc.
I am yet to find any articles or sample that can do this so any help would be greatly appreciated.
Many Thanks,
Rhys.

Do you mean the Combo Box control? If so then you use the Add method of the Items collection. ie. comboBox1.Items.Add("New Item")

Dim checkSQL As String
checkSQL = "SELECT OrderGenerate.OrderNumber, Client.Company, OrderGenerate.Completed " & _
" FROM Client INNER JOIN OrderGenerate ON Client.ClientCode = OrderGenerate.ClientCode " & _
" WHERE OrderGenerate.OrderDate= #" & dDate & "#"
Set RS = Conn.Execute(checkSQL)
If RS.BOF And RS.EOF Then
MsgBox "No orders yet today", vbExclamation, "No records returned"
Unload Me
Exit Sub
End If
The above is code that is located at the form load of the form. if no records are returned from the SQL statement, i wish the message box to be displayed and the form to be unloaded, however on run time, it crashes "object was unloaded" - is there anything i can do to fix this? any help would be greatly appreciated!

You can use RTF (using msWord for example) and convert them to *.hlp file (traditional Winhelp)
I read about that in (SAMS teach yourself VB6 in 12 days).. but I did not try it myself

I am trying to get the Data Environment to print to a Data Report
When calling the Data Report the Data Report appears but I get this error message
"Invalid SQL statement; expect 'Delete', 'Insert', 'Procedure'," etc
My code to call the Data Report is:
Clothing.Commands("Garment").CommandText = " & Text1.text & "
GarPrint.Show
My SQL Statement in the Data Environment is
SELECT ID, CustomerCode, StyleNumber, GarmentDispcrip, ScreenPrint, SizeRange, Embrod, FabricColour, FabricType
Can anyone offer any suggestions please  |

SELECT ID, CustomerCode, StyleNumber, GarmentDispcrip, ScreenPrint, SizeRange, Embrod, FabricColour, FabricType
you did not supply the FROM <table_name> part of the query
should be :
Select col1,col2,col3 from table_name

'Failed getting Rowset(s)from current data source'

Hello,
I am inserting a Recordset using a SQL statement, but when I call Open(), none of the Recordset Events fire (WillChangeRecordset, RecordsetChangeComplete, etc.). If I use the same Recordset with the same connection but change the Source to a new SQL statement, and call Open() again - all the Events fire.
Public WithEvents rs As ADODB.Recordset<br />
<br />
'conn is a valid ADO connection<br />
conn.Open<br />
<br />
'MySql is a valid insert command independently tested<br />
'The database is updated with the new record, but no Events fire<br />
rs.Open MySql, conn, , , adCmdText<br />
<br />
'Set new valid SQL <br />
rs.Source = "SELECT MyTable.ID from MyTable WHERE ID = 5"<br />
<br />
'Opening this fires all the Recordset Events<br />
rs.Open , , , , adCmdText<br />
<br />
rs.Close
Any ideas why the first Open() fires no events and the second fires all the events?
Thanks is Advance!
Derek

MySql is a valid insert command independently tested
I think first open doesn't fire events because it does not change the rs
it just inserts records in the DB
but the second is a select satement that changes the rs

to delete a row in a datagrid, i highlight the row and press a delete command button. this also works if i highlight the row and press delete on the keyboard. However, now i wish to perform calculations on the click of the delete command button. if delete on the keyboard is pressed, is there anyway to call the delete procedure? Thanks in advance!
