Re: Placing logout link on a MasterPage Christian Graus4-Dec-08 9:15 Christian Graus 4-Dec-08 9:15  I'm not sure that I see any issues at all, what are you thinking might be an issue ?

So I thought I better ask the forum. Thanks so much for your input. Ekjon populating listbox with file names valli rajya lakshmi4-Dec-08 8:29 valli rajya lakshmi 4-Dec-08 8:29  How to populate a listbox with all the file names from a given directory in the local drive at runtime.how can i hard code to get the directory name but not the file names.please anyone help me to do this. thanx valli Re: populating listbox with file names led mike4-Dec-08 8:46 led mike 4-Dec-08 8:46  valli rajya lakshmi wrote: from a given directory in the local drive at runtime local drive for which runtime.

Good luck led mike Re: populating listbox with file names valli rajya lakshmi4-Dec-08 9:17 valli rajya lakshmi 4-Dec-08 9:17  please can you help me in getting this. Re: populating listbox with file names Christian Graus4-Dec-08 9:28 Christian Graus 4-Dec-08 9:28  You can't do it in ASP.NET. You CAN do it in an activex control or java applet.

Re: populating listbox with file names valli rajya lakshmi4-Dec-08 9:30 valli rajya lakshmi 4-Dec-08 9:30  ok.is it possible when it is a server side ? Re: populating listbox with file names Christian Graus4-Dec-08 9:44 Christian Graus 4-Dec-08 9:44  Again - you cannot use ASP.NET code to read the file system on the client. You can host an ActiveX control or Java control ( making this not an ASP.NET question ) which will do what you want. Yes, by definition, these are hosted on the server and work on the client.

Christian Graus Driven to the arms of OSX by Vista. Re: populating listbox with file names Christian Graus4-Dec-08 9:17 Christian Graus 4-Dec-08 9:17  What you want is physically not possible. Imagine if you could write code that accessed a clients file system, deleting and looking at files ? No-one would use the web if this were possible.

[modified] ani04954-Dec-08 7:06 ani0495 4-Dec-08 7:06  hai this is anitha am developing an asp.net project on road maps . road maps are inserted in to a imagemap at runtime.i want to create a code for changing the color of the the entire road in which mouse is clicked . (imagine there is no junctions)the code should able to move through the road from starting pixel to the ending pixel of the line on both direction. thanks in advance modified on Thursday, December 4, 2008 1:12 PM Re: how to extract pixels from a image map using get pixel ?? Christian Graus4-Dec-08 8:29 Christian Graus 4-Dec-08 8:29  1 - don't ask twice 2 - there is no flood fill in GDI+, don't ask me why. You can interop to use the C++ flood fill method. 3 - of course, you realise that doing it this way means you need to use javascript to detect a mouse click, then send the point to the server, then the user has to wait while the new bitmap is created and then loaded on the client again ?

Christian Graus4-Dec-08 11:29 Christian Graus 4-Dec-08 11:29  Just to be more clear, there is no way you can do what you're asking in ASP.NET. If you want it to happen on the client end, it will have to be in an activex control or applet.

Now we have 2 servers.We are thinking to upload database to another server and website to other server. Is it giving us best performance rather than uploading database and site to the same server? please send your ideas about that. thanks in advance. Re: What is the best performance way? Christian Graus4-Dec-08 8:30 Christian Graus 4-Dec-08 8:30  It depends on a whole lot of things. 1 - how many users do you have ( is there a need at all ) ? 2 - how well written is the database code ? 3 - how well connected are the two servers ( are they in the same room, or is one in Paris and one in Delhi ) ?

Abhijit Jana4-Dec-08 18:21 Abhijit Jana 4-Dec-08 18:21  Along with the Point that has been mention by CG , you can read this one Improving ASP.NET Performance[^] cheers, Abhijit My Recent Article : Beginner's Guide To View State Web Services problem Ian Winter4-Dec-08 6:03 Ian Winter 4-Dec-08 6:03  I've created a few web services that have a ServiceStatus WebMethod that will eventually return the status of the web service. Right now I just get them to return a string just to make sure they work, eventually they'll return either "Good", "Critical", "Moderate". When I access the services and invoke the ServiceStatus method it works fine, if I try it a second time I get the following error: System.ArgumentException: An item with the same key has already been added. I think it may be because of the way my web services are architected. I have a base webservice that implements the ServiceStatus method and this web service class is declared as abstract, the ServiceStatus in the abstract class calls an abstract method, ServiceHealth which is implemented by the inheriting web services to respond with their health. So basically the base class has this: /// /// Returns the current state of the service /// /// <returns> [WebMethod] public string ServiceStatus() { return this.ServiceHealth(); } public abstract string ServiceHealth(); and then the inherited class simply implement ServiceHealth as: /// /// Returns a string defining the health of the service. /// /// <returns>Either "Good", "Moderate" or "Critical" public override string ServiceHealth() { return "Good"; } I don't understand however why it's keep name value pairs between invocations, shouldn't you just be able to call a web service, have it do it's thing and then have it die until it's called again at which point it starts afresh or have I misunderstood how web services work? This is obviously a fairly simple example as all I'm doing is returning a string yet having problems, I put together a full blown webservice the other week that worked fine so can only assume this is to do with the inheritance and such. Hope someone can help! Regards, Ian. Re: Web Services problem Wendelius4-Dec-08 8:08 Wendelius 4-Dec-08 8:08  If that's the whole code for service, I don't see any problems so I'd guess that the problem is at calling side. How do you invoke the webmethod and discover the service? The need to optimize rises from a bad design.My articles[^] Re: Web Services problem Ian Winter4-Dec-08 21:35 Ian Winter 4-Dec-08 21:35  Further investigation and I have to apologise, it was indeed nothing to do with those methods. In the constructor I add some settings to a static dictionary and when the web service is called again the constructor is called again to add to the static dictionary. I'm still a little unsure how web services work now then, is it the case then that all static classes remain between sessions and only the web service class themselves that are recreated each time a web service is called or something? Is there anywhere that explains exactly what is and isn't created when a web service method is invoked and what is/isn't destroyed afterwards?
