I want use a continuewith with a sub that have a parameter.See my exemple:
Public Sub a()
Dim t1 As New System.Threading.Tasks.Task(AddressOf b, 10)
Dim t2 As System.Threading.Tasks.Task[code].....
If you have
[Code]...
The question is when I do task.Wait(4000, cancel.Token) this should ultimately fail as the ContinueWith task won't complete within the timeout. It seems the Wait only applies to the Task and doesn't take the chain into account, how can I have it wait until the "chain" is complete?

View 2 RepliesIs it possible to make a procedure have a single parameter but the values for that parameter are more than one? I have this procedure:
Public Sub autoComplete(ByVal cboCombo As ComboBox)
With cboCombo
.AutoCompleteMode = AutoCompleteMode.Append[code]....
Now I was wondering if there is a way to use it like this:
autoComplete(myCombobox1, myCombobox2, myCombobox3)
Or can I use a procedure like this with 'With...End With'?
I have a method which requires a parameter to be passed in. I would like to use the Addhandler to call the method through a dynamically created button control's click event.

When I exclude the brackets, VS complains: Method '...' does not have a signature compatible with delegate...

One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.

What is the VB.Net that will do exactly the vbscript does? I like paramer(0) and 1 and 2 etc since I don't need to define the parameter(0) as integer or varchar etc. I remembered I have discuss this before and it is possible to do in VB.NET?

My query is this:
"SELECT TOP 5 * FROM [TableName] ORDER By NEWID()"
But I want to use a SQL Parameter so it could be something like this:
"SELECT TOP @ParameterName * FROM [TableName] ORDER By NEWID()"
The normal way dosen't work:
Ct.Command.CommandText = "SELECT TOP @ParameterName * FROM [TableName] ORDER By NEWID()"
Ct.Command.Parameters.AddWithValue("@ParameterName", SomeValue)
How can I add a Parameter in this situation?

in my app I use my sql commands with parameters. Now, I can't save the data in the database, because a parameter has an empty string value instead of a numeric value. And I want to know, which parameter it is. This command has 31 parameters.
My questions:
1. How can I loop through the parameters and print out it's values?
2. How can I print out the sql command with it's parameter values? (if it's possible).

I have an issue with the VB IDE My project was working fine.I was adding some combo boxes and adding some code for the combo boxes to the form "iNet_MDI". I ran it in debug a few times to watch it and the next thing I know, I see "Key not Found Parameter name:key" in the Warning list. It says the Warning is on line 369 in iNet_MDI.Designer.vb.When I click on this message, it takes me to line 369 which is "Me.gb_RTO.Font = NewSystem.Drawing.Font("Arial", 10.0!, System.Drawing.FontStyle.Regular,System.Drawing.GraphicsUnit.Point, CType(0, Byte)I can comment this line out and the warning still exists and it still points to the same line.
I have tried to rebuild the project and clean the project.I have tried commenting out alot of the code, but nothing seems to clear this warning message.

I am getting an error when I write a value to the database. it tells me "Key cannot be null. Parameter name: key". However the key is an auto-increment value and i'm not even writing to that field.

I also have other places within the same program that write to the database without any problems.[code]
