Otherwise you may have to handle the OnDataBind or OnItemCreate and insert the images as neccessary.

Xervanik6-Aug-02 10:46 Xervanik 6-Aug-02 10:46  The session_end event is Notoriously unreliable. The session doesn't officially end some 20 minutes (depending on settings) after the window is closed. And even that's not guarenteed. A possible solution might be to use some javascript with the onunload event in the body tag, but that seems iffy at best too. Sorry I can't be of more help.

I want to add a .txt to the end of a variable so that I can point to it as a file name. namePrefix = "catalog" Filename = join(namePrefix, ".txt") this isn't working so I must not have the correct syntax. If any one knows what it is I'd be very greatful. __________________ Re: Joining text strings in ASP Bullschmidt30-Jul-02 21:17 Bullschmidt 30-Jul-02 21:17  Filename = namePrefix & ".txt" Best regards, J.

Display a message box in an ASP.NET page Naresh Karamchetty30-Jul-02 10:55 Naresh Karamchetty 30-Jul-02 10:55  I am developing an ASP.NET application where a user will enter some infomation in a form, the information will be written to a database, and then I want the application to signal the user that the entry was successful or failed. One way to do this is to have the application display a message box. This is easily done with some client-side script, but I don't know how to do it from the server side. I want the message box to display after some server-side processing has taken place. I know that client-side functions can be associated with controls, but I have found that the client-side function of a control is called before its server-side event handlers. So, is there a way to display a message box from an ASP.NET page?

It just does not work that way. Best way to do this is have page1.aspx submit to the server, page1_processor.aspx then does the database stuff and then redirects once it is finished to page1_finished.aspx which has a JavaScript/VBScript alert box. However rather not even use an alert box as they are annoying. Just have a nicely formatted HTML paragraph on the page1_finished.aspx page. regards, Paul Watson Bluegrass Cape Town, South Africa The greatest thing you'll ever learn is just to love, and to be loved in return - Moulin Rouge Alison Pentland wrote: I now have an image of you in front of the mirror in the morning, wearing your knickers, socks and shoes trying to decided if they match!

There is no fool-proof way and definitley nothing as reliable as you can do in Windows apps. BUT there is an unload event in HTML. <body onunload="alert('Where are you going sucker?');"> I must stress that it is not foolproof. It does not always fire and there are ways the user can supress it (a lot of pron sites use this technique to stop you leaving their site, so a lot of pop-up buster software kills the onunload event.) I also dimly am aware of a "IsConnected" method in ASP (probably ported over to ASP.NET) which you can call from the server side to do some trickery. Not sure about it though. regards, Paul Watson Bluegrass Cape Town, South Africa The greatest thing you'll ever learn is just to love, and to be loved in return - Moulin Rouge Alison Pentland wrote: I now have an image of you in front of the mirror in the morning, wearing your knickers, socks and shoes trying to decided if they match!

Right now I'm using Integrated Windows authentication. Anyone logged into the domain has access (I think). I want to set the default permissons to only allow access to a few aspx files and require a login for access to the entire site.

DVryce30-Jul-02 5:48 DVryce 30-Jul-02 5:48  I've got a web app that uses the Microsoft remote scripting engine to run some ASP script on the server. This application works fine and has always worked fine without any version of the JRE installed. If I install the JRE version 1.3 (English edition) this application still works fine. If I install the JRE 1.3 (international edition) the remote scripting no longer works. Does anybody have any idea why installing the international JRE would hose my remote scripting? Re: Remote Scripting Hosed by JRE International? Jello30-Jul-02 22:27 Jello 30-Jul-02 22:27  The Remote Scripting solution from Microsoft isn't 'international character'-safe. Some characters cause the engine to fail. Have a look at the strings you are sending back and forth. Apache and ASP.NET Kevin McFarlane30-Jul-02 0:04 Kevin McFarlane 30-Jul-02 0:04  I've heard rumours that Microsoft may support Apache in ASP.NET and presumably in Visual Studio .NET. Does anyone know what percentage of Windows servers are using Apache? Naturally MS would prefer that everyone uses IIS. However, supporting Apache from within Visual Studio .NET could be a smart move for MS financially. 1) If there are substantial numbers using Apache on Windows and who are using a non-ASP server-side technology they could be persuaded to move to Visual Studio .NET and ASP.NET, thus increasing MS's revenues. 2) Substantial numbers of those running Apache on Unix or Linux servers may have chosen Unix/Linux because they prefer Apache to IIS and Apache has hitherto been better catered for on Unix. With Apache being supported within Visual Studio .NET they might be persuaded to go for Windows and Visual Studio .NET, thus increasing MS's revenues. Of course, those people running Linux rather than Unix may not be so keen to move to a Windows server. So scenario (1) is probably more likely. Kevin
