Re: AxInterop.xyz.dll deployment problem

I am actually surprised you were ever able to move those DLLs to the GAC folder. Anyways...

If you deploy the two Interop dlls to the same directory as the .NET application(s) where they are used, and ensure that the COM component from which they were derived is registered somewhere on the PC (the System folder or some folder where your company prefers to register COM components), you should be fine.

If you are using a .NET setup project for deployment, then you probably want to ensure that the 'File Installation Properties' Register property for the COM component is set to vsdrfCOMSelfReg (assuming it is a registered COM component). The Interop DLLs do not get registered; dropping them in the same folder as the application that uses them will be fine.

Is there a collection in .NET that combines the functionality of both a List and a Dictionary?

Hi gurus, I'm looking for a collection that combines the functionality of a list and dictionary. I basically want to be able to keep the order in which the items are added and at the same time do fast lookup? O(log n) as opposed to O(n), does this thing exist or do I have to write it myself?

If you can use a SortedDictionary, it's loopup is a O(log n) operation.

Otherwise you need to write it yourself. Just wrap a List and a Dictionary in a class, write an Add method that adds an item to both collections, and properties to get the values by index and by key.

Despite everything, the person most likely to be fooling you next is yourself.

Guess you have to write it yourself, like KeyList<T> with members List<T> and Dictionary<T> to which you delegate. But then I'm not a guru...

Does SortedList in the System.Collections.Generic namespace not work for you? It has a GetByIndex method along with key lookup!

Thanks for your reply, actually I want to keep the same order in which items are inserted, this is why SortedListed and SortedDictionary are not suitable for the job ..

Get Element which is clicked next

Greetings!

I'd like to do this:
I have a Button which defines the value of a bool Parameter:

public bool ListenMode { get; set; }
        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ListenMode = !ListenMode;
//TODO: Route all click Events to a self defined method
        }

Further I have a Grid which can contain certain Items.

What I want to do is, that if ListenMode is true, and the next element clicked on is one of those Items, get the item.

The problem (if it is one) is, that I don't know how to catch all the next clicks while ListenMode is true.

Any suggestions would be apreciated.

PS: It's done in WPF if this is of any matter.

Thank you in advance,
eza

First you have to specify what the rank for a web site should be in your application.

After that you should know what the input data needs to be so that you can collect it, and what formula to use to calculate the rank from the input data.

Despite everything, the person most likely to be fooling you next is yourself.

Use event DoubleClick from DataGridView.
If the event comes, then read the value, for example :

dataGridView1.SelectedRows[0].Cells[0].Value

Can someone give me an search and replacement pattern to regular expression for this convertion.

From text:

for (<br />
; rs.Read(); <br />
)<br />
{<br />
	AddFromRecordSet(rs);<br />
}

To text:

while(rs.Read())<br />

}

Thanks.

Im trying to clean up the messy code codedom creates...

CodeDom can not make While loops in CSharp language. it creates an for loop "which is actualy what an while loop is", but an developer, will always want to write an while loop instead of an for loop when it looks like i wrote above...

Thats what i want to do... Wink | ;)

I think I found the answer, let me know if its wrong:

Search pattern: \bfor\b $(.*?);\s(.*?)\;(.*?)$
Replace pattern: while($2)

RegOption.Singleline = on

Installer/setup file should support for single machine

Is it possible to create a installer/setup file and make it as a CD and we should use this CD in one PC. If that CD is already used in particular PC and that CD should not support other PC. Is this possible.

Thanks

1. That is no possibilities to write to CD (except if you have a CD Recorder)... Smile | :)

2. It's like Mission Impossible ... this CD will be explode in 5 sec.. Smile | :)

Change your application, that the user must be register first.
If you create a serial number for that PC, you must take for example MAC-Address for the serial number.
That means, that serial number is valid only for that MAC-Address. Not for other PC.

Another Link I found on the above mentioned page http://msdn.microsoft.com/en-us/library/ms996463.aspx[^]

It seems I need to work with low level implementations (Windows Messages/Hooks, etc.). I'm looking for something which works well with MS .NET runtime and possibly with Mono as well.

It would be great if I can find some custom (not extended) implementation of OpenFileDialog with Preview box...

Thanks for all the information...

The OpenFileDialog Class is also using Windows API.
That means, you must search it again. Until now, I don't found any 100% .NET Codes of FileDialog.

Differentt Typecasting for the same object

Hi All

Already developed client(Developing for OPC) I am having code like below

1. OPCserverObj = Activator.CreateInstance( typeofOPCserver );

2. ifServer = (IOPCServer) OPCserverObj;

// connect all interfaces
3. ifCommon = (IOPCCommon) OPCserverObj;
4.ifBrowse = (IOPCBrowseServerAddressSpace) ifServer;
5.ifItmProps = (IOPCItemProperties) ifServer;
6.cpointcontainer= (UCOMIConnectionPointContainer) OPCserverObj;

Create different types of objects(type castings) with the same source object.

Note: IOPCServer, IOPCCommon, IOPCBrowseServerAddressSpace ..etc are different Interfaces.

How to achive this? How to decalre to object to get all 6 points.

Thanks in advance for your help
