ASP.NET and the bigger picture - Web Development Discussion Boards

Hey,
I also have WinXP Pro, and I have had this problem. Certain ASP pages that I have written do not load. All it does is hang.

I also have access to a Win2000 Server. I wrote a ASP page, and tried to load it on my WinXP Pro IIS, but it did not work. I loaded the same ASP page on the Win2000 Server machine and it loaded fine.

There is obviously a difference between the two servers. Any help please. Smile | :)

I solved the problem by disabling Norton AntiVirus's "Script Blocking". If you have NAV you can try this:

1. Bring up NAV menu by double-click on NAV icon on the taskbar and choose "Options".

2. Locate "Script Blocking" section and uncheck "Enable script blocking".

3. Restart windows and the ASP pages should work properly.

Thanks! It works now. I am running NAV with Script Blocking. Smile | :)

I am using PWS on WIN NT workstation.

I am using out of proc component in my asp script.when I try to set ASPAllowOutOfProcComponent in IIS metabse,

Set oWeb=GetObject("IIS://LocalHost/W3svc")

oWeb.Put "AspAllowOutOfProcComponents", True

oWebService.SetInfo

It gives me error that
"Permission denied:getobject"

In one of MS's article I foung that we cant use out of proc component with IE for security reasons.

Please Help !!

Thanks,
patty

Patty,
I never could get that to work either. I will email you a small application that will do it. At least in Win2K allow-out-of-proc is set by default.

Hope this helps Smile | :)

Sorry the Changer.exe did not fix the problem. It will switch IIS to allow out-of-proc. I just noticed that you said you are using PWS. Are you using PWS or IIS? If you are doing any real web development you should be using IIS. I think it should get installed with the NT Option Pack. The NT Option Pack can be downloaded from Microsoft. My be someone else on Code Project can help with IIS on NT information.

I am using PWS.I have installed it from NT option pack from MS site.I am doing web based intranet application.

(Haven't got much time right now to flesh this thought out, but please feel free to develop it further)

Is ASP.NET really a step in the right direction when it comes to creating web sites?

The reason I ask is that I am having a tough time reconcilling ASP.NET into the XML and XSL (producing (X)HTML) vision of the web.

Yes, ASP.NET brings some wonderful features to the table. Being able to use a fully fledged language (like C#) instead of a handicapped scripting language is great. So is the concept of web forms with VB like controls (though they have a long way towards being really useful when you have cross browser and accessibility considerations.)

My concerns really have to do with when you are attempting to manage a large website which has both content-driven (e.g. an article page) and function-driven (e.g. a e-commerce ordering page) pages.

Currently we strive to ensure content is stored in XML files with XSL outputting XHTML to the client. This is great especially when you need to repurpose to different devices or you need to syndicate your content to other sites or applications.

When we need a functional page however it becomes a bit more complex tying it all together, but nothing too hectic.

Now however we have ASP.NET with code behind files. Programatically producing an Web Form is a lot trickier than a normal ASP page. Things need to be re-compiled, classes can't have duplicates etc. etc. This gives a CMS system a lot of extra stick really.

So just how does ASP.NET fit into the bigger picture of producing extensible, standards compliant and manageable websites?

Hi,
I have a small program written in VC which waits
for some client to connect to my listening socket
and then after some processing transmits a file to the
client

Now I want that my ASP page connects to that IP and socket
and retreives some information.

How can i do it in ASP.

Please help

well! i dont know about ur problem ! sorry about that !
but u can solve my problem!! can u send me ur application which u have created
if u can my address is zaki_01@yahoo.com
Thanx

I have a COM+ application that I can successfully use from a C# Windows Forms application. I am able to access the COM+ components via both early and late binding. No problem.

However, when I try to use the same COM+ app from an ASP.Net (C# code behind) application, I get a run-time error. If I use early binding I get an InvalidCastException for QueryInterface indicating the interface query failed.

If I use late binding I get a TargetInvocationException indicating the target does not implement IDispatch.

In the case of the early binding test, I've created an interop assembly via VS.Net, set a reference to it, etc. just as in the Windows Forms application. In both cases, I've set aspcompat=true in the aspx page. I've read the (very good) CP article on COM Interop by Aravind Corera as well as Tom Archer's C# (2ndEd) book, Adam Nathan's book on interop and others but I'm clearly missing something here.

What am I missing? Confused | :confused:

Just after posting, I discovered the problem. Blush | :O

I'm posting the solution here in hopes it will help someone else in the future.

It turned out to be an authentication issue. Adding the following line to the Web.config file took care of it. (So far...)

< identity impersonate="true" />

I seem to be having some trouble making a simple asp.net page. I don't know if it's because I'm simply to inexperianced or there is just some setting that I'm forgetting about in IE or IIS.

In VS.NET I create a new web application on localhost (yes, I do have IIS). I then double click on WebForm1.aspx and add a label, textbox, and button. I double click the button and type
Button1.Text = "Hello"
This is just something simple to get me started. Anyway, I build the solution and then click start w/o debugging. For some reason only the label is there. WHY??????????????????? Confused | :confused:

Are these server-side controls (e.g. <asp:button> ). If these are, did you remember to specify "runat=server"?

I made a custom webcontrol that reads records from a database and displays them in a webpage (as a list). However, I want each record to be clickable; and depending on the ID the control should do another query to update the list. I believe it's done with postback data but I can't find a good example or tutorial about this.

Does anyone have a good example of how to implement a custom webcontrol that handles postback data?

Already thanks!

hi,
How can I know, whether the client has left to another site, without logging out from a page in my site?I want the session to expire when he returns back to my site using the back button...

The validator controls (for example, the required field validator) does not seem to work in the netscape navigator browser. Has anybody come across this problem? Please provide me a solution. I could not progress in my work as I am stuck with this.

Thanks..

They only work in IE5 I believe since they make use of DHTML.

Hi all,

I am having trouble posting a form from a WinForm client.

-----------------------------------------------------------

// Winform code
WebClient myWebClient = new WebClient();
NameValueCollection myNameValueCollection = new NameValueCollection();

myNameValueCollection.Add("user", username);
myNameValueCollection.Add("pass", password);

byte[] responseArray = myWebClient.UploadValues("http://localhost/cent/Login.aspx", myNameValueCollection);

// Login.aspx code
string username, password;

username = Request.QueryString.Get("user");
if (username != null) username.Trim().ToUpper();

password = Request.QueryString.Get("pass");
if (password != null) password.Trim();

-----------------------------------------------------------

When I run it, asp.net never gets the username and password. What am I doing wrong? Thanks Smile | :)

It's Request.Form instead of Request.QueryString.

I have a dll for encrypt/decrypt. I can use it by P/Invoke from a C# desktop application without any problem. But if I call it from a ASP.NET application (also written in C#), it always fail to acquire a handle to the default key container (CryptAcquireContext) and create default key container (CryptAcquireContext). So could any one tell me what's the defference to call the dll from ASP.NET codes?
