I find it weird that this error occured when I don't have any properties assigned in the class. Below is my source code.

The application is using an xsd file which stores the data tables. Moreover, this stored procedure accepts 3 parameters.
LATEST UPDATE :I got this error "Object reference not set to an instance of an object." I'm now wondering where in the code I did not instantiate.

I have got this error and i want to know what property access is, i have deliberately not shown the line of code that it is to do with as i do not want to be given the final answer. I think i understand 'must assign to the property or use its value' does this mean that when setting something the object being set (as i am trying with font stlyle i will use it) font style must be set to bold or italic and then the bold font needs to be put somewhere?

start with I was given a program by a friend that was created in Excel 2003 with the help of Visual Basic Editor. He said he used Visual Basic 2003, which he is not 100% sure about. Anyways he used CurLine in the program and when I try to open it in Excel 2007 and then open the Visual Basic Editor and run the program I get the following error:Run-time error '-2147418113 (8000ffff)':Could not get the CurLine property. Unexpected call to method or property access.

I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
For all who can't read german:
"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.
Code I use:
Dim access As Microsoft.Office.Interop.Access.Application = Nothing
.
.
.
access = New Microsoft.Office.Interop.Access.Application()
[CODE]...
The Error occurs when I try to access any property of "access.Forms("frmTest")"

Is there a tab property I can assign to make a given tab not only the "top" (or active) tab but also the left most or is there another way to do this?(It seems pretty straight forward to make a tab the top or active tab.)The requirement is that I've got one tabcontrol that contains a potentially large number of tabs. Each member tab has a right fair number of controls and dialogs.These tabs are all grouped by fours sequentially. For example, tabs 0-3 are one group, 4-7 the next group, etc.I'd like to control the display of this tabcontrol from a different tab control. This second tab control contains high level information about the 1st tab control as well as a lot of other things pertaining to all four tabs that the user needs to see as well.For example, if I've got 8 total Tab1's, then I've got 2 Tab2's.When Tab2(0) is selected, I'd like Tab1's leftmost item to be Tab1(0). When Tab2(1) is selected, I'd like Tab1(4) to be my leftmost tab in Tab1, rotating the lower 4 out of view for the time being.

I am trying to assign a dataset to the TAG property of a textbox control in my application. The code seems to do the assignment without any error but I cant see the property TAG name or the assigned value using quickwatch etc. etc. The TAG property name does show in the design window.
Is this property useable in my version (academic 2002 version 7.0) or does the TAG and any assigned value it holds not show in quickwatch. I can only find 1 reference which seems to suggest the TAG property is not supported in early versions, but would prefer a definitive answer.

In my EF4 EntityModel I have an entity named Users. Users have the common UserName and Password string fields. If I do something like this
Dim u as new USERS
U.UserName = String.Empty
Then U.UserName are still Nothing.
But if I Do Something like this
Dim u as new USERS
u.UserName = "A"
u.UserName = String.Empty
Then U.UserName take String.Empty as value without problem.
The reason is the way that EF4 generate the UserName Property
Public Property UserName() As Global.System.String
Get
Return _UserName
End Get
[Code] .....
I do not want to make two assignations every time I want to set string.empty to a property with a nothing value, and I do not want to remember that I must do it in this way everytime, because I'm pretty sure that I will forget it and then I will introduce bugs in the code. I just want to assign the empty.string value to a property and the property take "" as value.

I'm setting up a simple helper class to hold some data from a file I'm parsing. The names of the properties match the names of values that I expect to find in the file. I'd like to add a method called AddPropertyValue to my class so that I can assign a value to a property without explicitly calling it by name.The method would look like this:
//C#
public void AddPropertyValue(string propertyName, string propertyValue) {
//code to assign the property value based on propertyName
}
'VB.NET'
[Code]...
Is this possible without having to test for each individual property name against the supplied propertyName?

So if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this
