I have read several places that indicate this should work, but it doesn't. The selectSingleNode blows up with "Error: Object variable or With Block variable not set."
i have this error in the line of with xl.active......Object variable or With block variable not set.

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.

View 2 RepliesI have written a program and I think it is fine except for one error. "Variable 'intIndex' hides a variable in an enclosing block". i have a feeling this is something easy but have been trying to fix it and have failed miserably. I'm surprised I have any hair left!

In this VB.NET code:
Dim o as SomeClass
Try
o = new SomeClass
'call some method on o here
Catch(...)
Why is there a need to set o to Nothing? What if i don't set it to Nothing in the Finally block? What i think is that it is OK if you don't set it to Nothing because the object will be marked for GC.
when I create a listview item programmatically and add listitems I get error "The object variable or with block-variable is not set".This occurs only when the listitems are added on another place then where the listview is created.
View 7 RepliesI am using the VB ReportViewer and report designer. I am not using the report wizard as I have had no success creating the report I want that way (I'm new to all this).
I have created a view holding all the columns I want to report on. Half the columns have values to be displayed in the body of the report in tabular form. The other half contain values on which I wish to group. Although there are several columns in this set, the values do not change except when the group value changes. Eg
Group col1
Group col2
Group col3

I cannot discover how to achieve this using the tools provided with the report designer.

This is part of some code that will run without user interaction once it's spinning away, and I need to create a unique object from some items found in a StringCollection, naming the objects using information found in the strings stored in that StringCollection.
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"
