- 1. Add COM+ Reference to C#.NET Assembly
Mike001, The reason this is happening is that TLBIMP sees that the type library is for an existing .NET assembly. Because of this, you should just add a reference to the .NET assembly itself, and not to the type library used to expose the object to COM. Hope this helps. -- - Nicholas Paldino [.NET/C# MVP] - XXXX@XXXXX.COM "Mike001" < XXXX@XXXXX.COM > wrote in message news: XXXX@XXXXX.COM ... > I'm new to C#.NET and am building a windows service program.

In the Add Reference dialog, the component does not appear in the list. When I browse to the folder where the DLL and TLB files exist and select the TLB file (which was generated by RegSvcs) I get the error: A reference to 'X.tlb' could not be added. Converting the type library to a .NET assembly failed. Type library X was exported from a CLR assembly and can not be re-imported as a CLR assemby. > > Does anyone know what this message means and what I need to do differently to add the reference to my project? > > Thanks - 2. Custom validation
Hi! I've been experimenting with server side custom validation and I can't make it work. I have a text box which I'd like to validate by sending the content to a web service which will check it and return 0 or 1. I've added a custom validator control in VS .Net 2003. The code looks like this: <asp:CustomValidator id="CustomValidator1" runat="server" ControlToValidate="CVRNummer" ErrorMessage="TEST"></asp:CustomValidator> By double-clicking the control the follwoing was added in the code-behind file: private void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args) { } I've tried to add all sorts of things to this Sub to make something happen but so far nothing has worked. My last attempt was this: private void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args) { Label3.Text = "TEST"; } which unfortunately didn't give me the expected result. Can someone help me out here? Best regards Morten - 3. How to create dependant properties???????
Hi all, I'm creating a simple user control that has two properties that represent a range of valid integer values. For example: int minimum, maximum; public int Minimum { get { return mimimum; } set { minimum = value; } } public int Maximum { get { return maximum; } set { maximum= value; } } // P.S. I've deliberately made this simple to avoid cluttering code. Using the properties window, I would like the programmer to be able to set the minimum and maximum values to a proper range - for example Minimum = 400 and Maximum = 800. The rules are that the minimum value must be <= to the maximum value and the maximum value must be >= to the minimum value (a circular dependance on each other). Thus, setting the properties to Minimum = 800 and Maximum = 400 would be illegal and the code would prevent this. Does anyone know of a way of doing this using two separate properties or can it be done with one property or some other method I may have overlooked? Any ideas would be appreciated.

Hi, we are porting an existing VB/COM application on .NET. This application is typically a mailing engine. For sending mails it uses CDO. As part of development in .NET we are using System.Web.Mail namespace. Mails can have attachments also of different types as word files, html files etc. But there is a case when a previously sent mail need to send as attachment in the new mail, means attachment type is an Outlook item. For this existing application uses IBodyPart interface and function SaveToObject, but THERE IS NO CORRESPONDING FUNCTION OR CLASSES in .NET library, and we dont want to use COM interop to use CDO library. Is there any possible way to do that, without using any COM libraries. Thanks in advance Brajesh Jain

Use System.Xml.XmlDocument. Load file into object with Load method.
Use SelectSingleNode with XPath to find the element you wish to delete.
XmlNode elemToDelete = dom.SelectSingleNode("xpath here");
elemToDelete.ParentNode.RemoveChild(elemToDelete);

2.ASP.NET 2.0 Tree Control and Navigation Controls - General Question
Hi. Why is it practical to have the ASP.NET navigation controls based on XML? I would love to just use databinding and then be able to dynamically update the navgiation menu (e.g. for a product list). I tried to use a dropdownlist with hyperlinks for navigation (not the main navigation -- a navigation subset) and even a listbox, but found it very cumbersome. The way I figure it now, is that I have to pull the data over from Sql Server, convert it to XML, reformat into the appropriate nodes, and the then populate the navigaiton control.. Is there an easier way to do this? What am I missing?? Thanks in advance! -Ranginald
