Folks... I'm a newbie n hope some1 can help out here..I've a VBA Application (Intranet) which I'd need to check users role and authentication to enable/disable some components. I created a COM Class so that I could expose some properties of the IPrincipal Interface on the .NET framework for the VBA to check the roles...more like implementing.... If Me.User.IsInRole("MTN_Grp") Then .... If My.User.IsAuthenticated = True Then ...... The created COM Class builds perfectly...but can't figure out how to implement these on the VBA side or whether some more code is needed...Please check the attachment. Any help will be much appreciated.:confused: Tx CCW_Auth…

Hi All, I have written a little web site that has a log in page. Once the user logs in I set a session variable to flag this event. When the user logs into the admin section there is a check on this variable to see if they logged in correctly and didn't just put the address in the address bar instead. On my local machine this works great for both I.E. and Firefox. However when I publish it on my Windows Server 2003 box it works great with Firefox but with I.E. the session variable is null once the admin page loads. Does anyone know why this is happening? Cheers, Dave.

I'm trying to acces "My.Computer.Clipboard" from a thread and I get an error "Object reference not set to an instance of an object.". Any ideas where I go wrong?? Here is my code (Form1 + one class). The program listens for a printscreen press in a low priority thread. And once the print screen is pressed it should save the picture to disk, but thats when I get the error. Form1 code: Public Class Form1 Public Shared Snooper As New SnoopClass Public Shared ImageCounter As Integer = 0 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Start snooping for Print Screen key press Snoo…

Hi, My visual studio crashed today and I had to restart the pc, now the project I was working on just wont compile. I get the following errors Error 1 The item "obj\Debug\eMatrixAdminSystem.frmMainLayout.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter. Error 104 'Private Sub InitializeComponent()' has multiple definitions with identical signatures. How can I fix this, i've looked in the designer section of my form and the InitializeComponent method is only there once. Hope someone can help. Thanks

Hi all I am in the process of setting Visual Studio.net 2005 up on a new networked machine. Everything appears to have installed correctly, I have created a test application (hello world) that has a single page with the words "hello world". My problems occur when I try to run the project, as per normal the project runs from http://localhost/testapp/default.aspx. However I am getting a page cannot be displayed error. If I change the address and replace localhost with either my machine name or 127.0.0.1, the page will run correctly. Any suggestions on what I can do to solve this problem, one thing that I was considering was making a change to the virtual directo…

VS 2005 C# SP1 always use the same executable file whenever I try to run my project, I've tryed to build, rebuild the project but the he puts always in the ...\Debug folder the same outdated .exe file. It also skips any error in my project which forces me to believe it is not compiling the code at all... Any Suggestions?

I'm trying to convert a C# class into VB.net and have come up with a problem. The C# code is: public event MouseEventHandler OnMouseActivity; public void MySub() { if (OnMouseActivity != null) { } } And I would have guessed the VB.net equivalent is: Public Event OnMouseActivity As MouseEventHandler Public Sub MySub() If OnMouseActivity isnot Nothing Then End If End Sub But that does not work. The error message is "... is an event and can not be called directly." It's obviously some difference in the syntax in the way events are handled. I know that in C# you can call an event much like a function, but in VB.net you must use RaiseEvent. But upon fur…

I'm not sure the best way to do this. I need to write some unit tests that test that certain users have the ability to do certain things; the objects have role based permissions. The problem is that in order to do this I have to impersonate one of 4 test users to get the permission set that is going to be tested. While impersonating myself is quite easy I can't find any .NET libraries that allow me to create a Windows identity/principal and make the unit test run in the context of that user. Any ideas would be greatly appreciated. I'd prefer not to hit the Windows API's if possible; if that is the only solution, a pointer to someone who has already wrapped Logo…

I am using the following to generate a field in a gridview. Is there a way to format the data? specifically this is a returned date of 1/1/2007, but it displays the 1/1/2007 12:00. I need to drop the 12:00. THe backend is SQL Server 2005. Do I need to format it there? <asp:TemplateField HeaderText="SD" SortExpression="StartDate"> <ItemTemplate> <asp:Label ID="Label15" runat="server" Text='<%# Bind("startdate") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtStartDate" runat="server" Text='<%# Bind("startdate") %>'></asp:TextBox> <…

I think Microsoft really stupid in allowing their high-end .net language to be decompile-able. What a joke? I had secure my VB6 application from decompiled in the olden day but, now in this new age, with this modern technology, my application is decompiled by my competitor. The source code is not a problem, but, the logic I had been written all this while. They just decompile and with just the first few classes, they got the logic on how do I communicate with my Dongle, how do I calculate my Activation code. What the f**k. seems few thread in extreme forums. Doesn't seem to have a real good solution/cure for this issue. Kinda fed up with this product now. I …

I was looking at my SQL Server 2000 Error logs. I noticed that just about once an hour i get the following error. Should I worry about it?

Hi what is the mechanism for which I could use to add functions to lists of certain classes? I'm guessing that there is one. So I want these lists to have some of the same functions: List (of Class1) List (of Class2) List (of Class3) The specific functions I'd want to add are like: .GetObjectFromName .GetIndexFromName So Each of Class1, Class2, and Class3 have a variable named "Name" I know about how to use interfaces but I'm not sure about how add an interface with a pre-existing class or collection object. Thanks
