I haven't finished looking through the documents yet but the IBuySpy.com site has ASP.NET best practices sample apps for a store front and portal site. Examples are available in both VB.NET and C#. So far it looks good although i'm no expert. Frown | :(

Writing (not using) Asynchronous Methods

Heath Stewart24-Sep-02 14:17

24-Sep-02 14:17

For a psuedo-serialization method I'm doing to persist a tree view (the reason it's psuedo is because I don't want the TreeNodeCollection serialized as an element), I have two method signatures like so:

public void LoadNodes(XmlNode xmlRoot, ref TreeNode treeRoot);
public void SaveNodes(TreeNode treeRoot, ref XmlNode xmlRoot);

What I'd like to do, since this could be a fairly lengthy operation and needs to be done on 4 separate trees, is provide our framework application with Begin* and End* functions for asynchronous processing.

I've worked with threading a lot and have used asynchronous methods many times in the past, but I'm having problems imlementing it myself. I've written basic asynchronous methods were the state object is enough to pass custom values. I've read about all I can on it, and all the examples reference methods of the MulticastDelegate class that don't exist (I'm guessing these were .NET pre-release articles). I've also considered just returning Control.BeginInvoke and getting the object from Control.EndInvoke, but neither of my methods above return anything (hence, void - and there's a good reason for it).

Has anyone written any asynchronous methods that could help me? TIA

Okay, after reading an article in the docs one last time, I caught something I obviously missed last time. If you use the correct method signature, the compiler will generate BeginInvoke and EndInvoke automatically. It wasn't showing up in the Intellisense menu - nor the class documentation - so I never noticed it before.

Automating Word application in C#

Hi all,
I am trying to write some small app that automates Word Application (mainly MailMerge, and sending word documents to the printer), and I have come to a problem.
Using the Missing.Value as a missing parameter (which is a good thing to do in every other method of the word app) will not work as most of the methods need a ref object as a parameter.

does anyone have a clue?

thanks
Noam

I attach a small piece of code for example.
this code does not compile, for the above reason.

<br />
Word._Application word = new Word.ApplicationClass();<br />
					Word.Document doc = (Word.Document)word.Documents.Open(ref m_confirmationFile,<br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value);<br />
					Word.MailMerge mailMerge = (Word.MailMerge)doc.MailMerge;<br />
					mailMerge.CreateDataSource("Data.doc", Missing.Value, Missing.Value, <br />
						"CandidateID, FirstName, LastName, Address",<br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);<br />
					Word.Document dataDoc = (Word.Document)word.Documents.Open("Data.doc", <br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value, Missing.Value, Missing.Value, <br />
						Missing.Value, Missing.Value);<br />
					Word.Table tbl = (Word.Table)((Word.Tables)dataDoc.Tables).Item(1);<br />
					tbl.Cell(2, 1).Range.InsertAfter(candidateId);<br />
					tbl.Cell(2, 2).Range.InsertAfter(firstName);<br />
					tbl.Cell(2, 3).Range.InsertAfter(lastName);<br />
					tbl.Cell(2, 4).Range.InsertAfter(address);<br />
					dataDoc.Save();<br />
					dataDoc.Close(Missing.Value, Missing.Value, Missing.Value);<br />
					mailMerge.Destination = Word.WdMailMergeDestination.wdSendToPrinter;<br />
					mailMerge.Execute(Missing.Value);<br />
					doc.Close(Missing.Value, Missing.Value, Missing.Value);<br />

string s = @"c:\mydoc.doc";
object so = (object) s;
object o = null; 
Word.Document doc = word.Documents.Open(ref so,ref o,ref o,ref o,ref o,ref o,ref o,ref o,ref o,ref o);

(the ref stuff is because the tlbimporter is stupid, and prefers to assume nothing, even when the type-library brings everything top-to-bottom and left-to-right).

Have fun!! Cool | :cool:

AppDomains and CodeDOM

23-Sep-02 12:09

Has anyone had any experience or seen any articles about using AppDomains and the CodeDOM classes in the .NET framework in a similar way to ASP.NET? I would like to be able to compile extension code for my app that provides user specific customisation. Hopefully the extension code will have full access to the object model of my app including instances of objects hosted inside the main AppDomain.

I guess it's the efficiency of marshalling calls between AppDomains that i want to understand so i can make best use of them.

Thanks

.NET ComboBox Item Tags (SetItemData equivalent)

I am trying to set tags for individual Combobox items. In looking through the Combobox doc, I cannot find the equivalent of SetItemData/GetItemData. The tag property is set at the Combobox level, and not at the item level. Can someone point me to an example, or how to set the tags for invidual combobox items. I would like to store database record ids as tags in the combobox.

Unfortunately there isn't. However, if you considered switching to a ListView instead of a ListBox, then you would be able to use the ListItem.Tag property. And, it functions almost like a listbox...kind of.

Auto-updater?

17-Sep-02 16:46

Aloha everyone...I have a question:

How can I implement auto-updating to my app? I have created a simple TCP/IP application and I would like the client to be able to get the newest version from the server and overwrite itself with the new version.

Obviously this will create problems with trying to overwrite a file in use, so how do you do it?

- Does .NET provide built in "shadow copying"? (I know ASP.NET does)
- Does Windows provide a service to auto-copy a file once an application closes?
- Is there some black-book trick I am unaware of???

Any help would be really appreciated!

.NET has several capabilities that you could possibly try. My companies application is Internet-distributed and actually launched from the web and downloaded automatically into the Temporary Assembly Cache (TAC, kept safe from other applications). Based on the .config file on the server that the application uses, we can easily update a DLL, modify the <runtime> section of the .config file and change the binding to the new version, for which the application will automatically grab the new one and download it, inserting it into the AppDomain.

As far as automatically updating files that are in use, you don't really want to overwrite files. This is not necessary and not recommend in .NET. You could install the assemblies in the GAC, for which each one gets a separate directory (for which you don't see) and you can have several versions of assemblies in there. Then, using the application's configuration file, you can use a <bindingredirect> to tell the application (which is bound to a previous version of an assembly) to now use the new one. See the <bindingredirect> element in the .NET Framework docs for more information.

I hope that gives you some insight for ways to keep your application up-to-date on client machines.
