Hey all,

I'm getting a really annoying error when trying to save my xml document. I was using the example from the MSDN and it failed to with the same error. Here's the current code:

Friend Sub upload()

'create xml doc
Dim XMLDoc As New XmlDocument

'get all controls from form1
Dim ctrl As Control = f1.GetNextControl(f1, True)

'if the control is a special type called unitbox
If TypeOf ctrl Is UnitBox Then
'set it to x
Dim x = DirectCast(ctrl, UnitBox)

'if unitbox.unittype falls in the case
Select Case x.unitType
Case "infantry"

Dim inf As XmlElement = XMLDoc.CreateElement("infantry")
inf.SetAttribute("number", x.number)
inf.SetAttribute("location", x.endcountry)
inf.SetAttribute("owner", x.owner)

'also tried xmldoc.appendchild(inf) to no avail
XMLDoc.DocumentElement.AppendChild(inf)

'more cases... all the same stuff though
End Select
End If

'gives a system error
XMLDoc.Save("testxml.xml")

End Sub

Thanks a for any help Big Grin | :-D

What kind of error specifically? Is it an access denied error? You're telling it to save as testxml.xml. but what directory are you running in? Did you set the DocumentElement to something before appending children to it?

I need to capture the Ctrl+Shift+C keys even when my form does not have the focus (more like a service running without an interface).
Can anyone help?

There are many ways,
1. using Timer and call GetAsyncKeyState
2. using MenuStrip
3. using contextmenustrip

All you have to do is convert the C# code to VB.NET. I haven't found any VB.NET examples and, frankly, have no time to convert them myself.

AxWebBrowser- switch off internet explorer keyboard shortcuts

HY!

I'm using the AxWebBrowser component in my current vb.net project to be able to use my app as a browser! I want to switch off the internet explorer keyboard shortcuts, but I don't know how i can handle this with the AxWebBrowser tool. I know it's possible to do that with the standard vb.net 2005 WebBrowser tool in vb developer 2005 ->

WebBrowser1.WebBrowserShortcutsEnabled = False.

But there's a bug in the WebBrowser (navigating thru macromedia flash sites isn't possible http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=142772&SiteId=1[^]) component, so I have to use AxWebBrowser.

thx!

Use the ImageList for storing your images before displaying into the listview

Yes I know this, the only issue is that the imagelist's items property is read only and images cannot be added programatically, is there anyway to sotre a virtual indexed list, like a string.

More than likely not. Pretty much, the only thing you can do is another Compact and Repair. Don't you just love Access?!?!

Use a boolean variable and assign it "True" or "False" as necessary.

usually that error raise because of we forget declaring new instance of an object in vb6
try this

...
dim DB as new adodb.connection, tick as string
if answer=vbyes then 
tick="True"
db.connectionstring="provider=microsoft.jet.oledb.4.0;data source=c:\db1.mdb"
db.open
db.execute "UPDATE Dono SET InvoicePrint = " & tick & " WHERE [NO] = "'" & dorder.dono.text & "'"
end if
end sub

There is error:

DB.ConnectionString = "provider=microsoft.jet.oledb.4.0;data source=c:\db1.mdb"

ups, my mistake, you should replace c:\db1.mdb with your database location, and you should use db.open instead of db.opendb methods, good luck D'Oh! | :doh:
