Why does the Child form always appear behind the other controls on the form?
|
|
|
|
|
Because the MDI CHild formis being rendered inside another control on the Parent form, called the MdiClient. Putting controls on the surface of an MDI Parent will always have them show up on top of this MdiClient control.

Hi,
I've been trying to work out how to iterate through a collection object using reflection.
I have a class with a few simple objects, strings, single[] arrays, and one collection.
However, when I'm using the GetFields() method to retrieve the objects in my class, when it gets to the collection I am unable to view all the items in the collection.
dim coll as collection = FieldInfoObj.getvalue(obj)
console.writeline("Collection has " & coll.count & " items in the collection")
for each item as object in coll
do_stuff(item)
next
Although it correctly states that I have 4 items in the collection, item 1 is Ok. item 2 is 'nothing' and item 3 causes an error. But I do actually have 4 'singles' in the collection.
How do i access the collection objects using reflection?
I *think* I need to reflect into each object seperately, and not just iterate through them after setting the main collection object using the getvalue(obj) method as I would with the other system.xxx type objects (which work fine)
Could anyone provide a simple example of how to iterate through a collection using reflection?
Thanks in advance,
Phil.

Hi,
I am calling a web services in VB.NET. The code is almost done but I am getting an error at shipping section that I don't know how to fix. I think it is very simple but I don't know how to figure it out.
Error is “Too many arguments to ‘Public Sub New()’ at value 1” at this line “Shipment.ShipmentItems = New ShipmentItem(1)”. I am not still sure that this is the right way of calling shipment class because shipment is a sub-class of salesorder.

The error is telling you that your call to "New ShipmentItem" shouldn't have (1) on the end of it.
Whether or not you are using it correctly is for you to decide.

Thanks for looking at this issue.
If I remove (1) from 'New ShipmentItem(1)' and make the line like this
Shipment.ShipmentItems = New ShipmentItem
then this error is coming.
'SendOrdersToSC.SalesOrder.ShipmentItem' cannot be converted to '1-dimensional array of SendOrdersToSC.SalesOrder.ShipmentItem'
What I should do?

How about creating an array of ShipmentItems?
Dim shipItems() As ShipmentItems
Shipment.ShipmentItems = shipItems

Thank you.
This is fixed.

Hi
I have writing the followin function which catches a datagrid link button event, which should take the user id from the selected record and pass it into a stored procedure, and then refresh page, with the selected record deleted.
It all seems to work perfectly fine, but it jus doesn't delete for the some reason
I have also ran the procedure through a command window and that works as expected
here is my code for dealing with the button click and passing the parameter into the stored procedure
any help or spotting of my retarded mistake would be much appreciated
cheers
boyindie
Sub DataGrid1_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) Handles dgPriv.ItemDataBound
Dim l As LinkButton
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
l = CType(e.Item.Cells(6).FindControl("cmdDel"), LinkButton)
l.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this item?');")
End If
End Sub
Sub dgpriv_ItemCommand(ByVal sender As Object, ByVal e As DataGridCommandEventArgs) Handles dgPriv.ItemCommand
Dim iid As Integer = dgPriv.DataKeys(e.Item.ItemIndex) 'Grab the ID from the hidden column
Dim litErr As New Literal
Dim myConnection As New MySqlConnection("Server=localhost; ;database=test;")
Try
Dim param As New MySqlParameter
Dim myDeleteCommand As MySqlCommand = New MySqlCommand("sp_mydelete", myConnection)
myDeleteCommand.CommandType = CommandType.StoredProcedure
param = myDeleteCommand.Parameters.Add("?p_id", MySqlDbType.VarChar)
param.Direction = ParameterDirection.Input
param.Value = iid
myConnection.Open() 'Open the connection
myDeleteCommand.ExecuteNonQuery() 'Delete the record
myConnection.Close() 'Close the connection
Catch ex As Exception
litErr.Text = ex.Message
MsgBox(ex.Message)
End Try
refresh()
End Sub
and this is my asp code

Your current code seems to be right, the only reason I can think of is you have done some silly mistake in your stored procedure. Did you debug the code? Does it get the iid value you want to delete?
If it gets through your myDeleteCommand.ExecuteNonQuery() line without any exception, it bound to be the stored procedure.

ah the joys of copy and pastin previous code and forgettin to change the database name to the one you want to use!
It was working fine it was jus using the procedure of the same name in the wrong database!
cheers for your help

My program needs to access and manipulate a table created by a third party vender. We want to catch when the table or tables are updated. When i set up the connection and set up the Adapter, I get a error when I try to access the tables saying that I don't have permissions. but some tables I can access. What do you suggest I do? Is there a query in Access I can do that updates every time a table or tables change? then I could access that query or have that query write to table that I can access. Keep in mind that I want to update the original table that I don't have access to.
Any ideas?

Cory Kimble wrote: Is there a query in Access I can do that updates every time a table or tables change?
No. Access databases do not support triggers. There's no way to capture when the database is updated from any and all sources.
The only way this can happen using Access is if all database transactions are done through a component that you write to do all the database work. All other applications that use that database MUST also go through your component.
Cory Kimble wrote: Keep in mind that I want to update the original table that I don't have access to.
Then you're not going to access what you don't have permissions to. If you don't have to permissions, you're not going to get them unless they are granted to you by the admin of the database. No permissions equals no update.
In your situation, you simply have no options.
|
|
|
|
|
Does the third party software keep a log of table changes? If so you could import that into your db.

No log. But, It has a query in the database that updates automatically. Is there a way I can use that?
|
|
|

Cory Kimble wrote: It has a query in the database that updates automatically
There is nothing in Access that updates THAT automatically. You'll have to find out what's making this change. That's IF you have to rights to poke around the database that much.

Hi,
Why is it not possible to make the value variable of a property setter ByRef? actually i need to access multiple properties of a calling form in the class and was therefore trying to pass the reference to the form to the class. Is there any way around this?
Thanks in advance!
Ahmad

You can't change the Setter to ByRef. It also doesn't need it. A property setter is expected to NOT change the object being passed to it, so why would you need a Ref to it??
Ahmad Zaidi wrote: i need to access multiple properties of a calling form in the class
??? Post a copy of the property code so we can see what you're trying to do. It sounds like you;re trying to exceed the bounds of what a property should be doing.

|

You are confusing a reference with passing parameters by reference. You don't need to pass a parameter by reference to pass a reference as a parameter.
You only pass parameters by reference when you need to change the variable that you are passing as a parameter. The default way of passing parameters is by value. For a reference type it means that the value of the referece is passed, i.e. a copy of the reference.

I want to write a windows service application that reads a web page. That web page requires that the client can process javascript.
Has anyone successfully implemented Javascript with System.Net.WebClient?
I tried the code from the article "A simple .NET based WebClient with JavaScript support" but that code crashes with an inner JScriptException. Its acknowledged by the author and it looks like the trail ends there.
According to microsoft the Microsoft.JScript.Vsa.VsaEngine used in that project is deprecated.
What is the current working solution for processing webpages in code?
This is what my code looks like. The web page at the URL I am calling uses javascript to set a cookie in order to prove that Javascript is running. It doesn't look like this code can do it. I can set cookies in advance but I can't seem to duplicate the javascipt setting a cookie. Help!
Dim webClient As Net.WebClient = New System.Net.WebClient
webClient.Credentials = System.Net.CredentialCache.DefaultCredentials
webClient.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)")
webClient.Headers.Add(Net.HttpRequestHeader.Cookie, "aCookie:aCokievalue")
Try
Dim data As Stream = webClient.OpenRead(sURL)
Dim reader As New StreamReader(data)
Dim s As String = reader.ReadToEnd()
'response = webClient.DownloadData(sURL)
'Return Encoding.ASCII.GetString(response)
Return s
Catch ex As Exception
Return ""
End Try
