# re: AJAX .NET Wrapper DLL Video

Sorry Mate but I can't unzip the file. I'll get a

"Error in file #1: bad Zip file offset (Error local header signature not found): disk #1 offset: 0"

I wonder if others have teh same problem and ther's someting wrong with the zip file.

Cheers

# re: AJAX .NET Wrapper DLL Video

Thanks for the demo. What happens if you change page after executing an asynchronous call?

Sometime ago, I also played on a similar capability by Alvaro Mendez ( http://www.codeproject.com/aspnet/AlvaroRemoteScripting.asp ) but this is a different approach I should say.

# re: AJAX .NET Wrapper DLL Video

Sorry, there was an error while uploading the ZIP file. I have started the upload of the new ZIP file. In 10 minutes the new file should be on the server...

# re: AJAX .NET Wrapper DLL Video

If you change the page after invoking the method on the server will have no effect for the execution. The method will finish and trying to return the result. But there will be no client request running and the result will be trashed...

# re: AJAX .NET Wrapper DLL Video

if you have "." in the namespace an error is thrown
do
<script language="javascript" src="vbwrapper/common.ashx"></script>
<script language="javascript" src="vbwrapper/X.Y.test,X.Y.ashx"></script>

throws an exception

great work btw

# re: AJAX .NET Wrapper DLL Video

csharpwrapper/WebForm1,CSharpSample.ashx in Browser. I use the examples in csharp.

# re: AJAX .NET Wrapper DLL Video

@Ashish Jaiman: Can you please send me the sample VB.NET class file? Or the VB.NET project files? Are you missing the web.config httpHandler setting?

@Christoph: Can you send me the project you are using? Are you using the sample solution?? Are you using a IIS root application or a virtual folder?

# re: AJAX .NET Wrapper DLL Video

I use the csharp-default as is in an existing project(copy and added the httpHandler-lines in web.config. I use it in an virtual folder /localhost/smspower/default.aspx

# re: AJAX .NET Wrapper DLL Video

where do i send the erroring out project
but to recreate it is very simple ( or may be i don't know what to change in the javascript registration on the page) but if you change the name of the assembly to VBNETSample.UI ( fromt he project properties) it blows up - i guess i am using the invalid script registration

<script language="javascript" src="vbwrapper/common.ashx"></script>
<script language="javascript" src="vbwrapper/VBNETSample.UI.WebForm1,VBNETSample.ashx"></script>

thanks a lot

# re: AJAX .NET Wrapper DLL Video

@Ashish: the current release will not need to add those script TAG lines. You can use Ajax.Utility.RegisterTypeForAjax(typeof(WebApplication1.WebForm1)); This method will write both of those lines!!

I will upload a documention for the Ajax.NET Wrapper DLL this night.

# AJAX Wrapper for .NET

So much for fast speedy interactivity on the web. Here comes AJAX Wrapper for .NET (v1.1). No more postbacks!...

# re: AJAX .NET Wrapper DLL Video

even registering for javascript wont' work - it throws an exception if there is a . in the assembly name - like VBNETSample.UI

Ajax.Utility.RegisterCommonAjax()
Ajax.Utility.RegisterTypeForAjax(Me.GetType)

# re: AJAX .NET Wrapper DLL Video

Hello Ashish, it is working with a dot in the assembly name. I think you have to register something like WebApplication1.WebForm1 instead of Me.GetType. ASPX files will be compiled to another class that will be there only temporary. Can you send me a sample where it is not working?

# re: AJAX .NET Wrapper DLL Video

I have having the same problem as Ashish, I'm running my application under the virtual directory "testmanager"

this is what's generated using RegisterTypeForAjax

<script language="javascript" src="/testmanager/ajaxwrapper/common.ashx"></script>

<script language="javascript" src="/testmanager/ajaxwrapper/testmanager.Objects.UIL.Login.Login,testmanager.ashx"></script>

I have a code behind method under the class "Login.cs" in the namespace

"testmanager.Objects.UIL.Login"




[Ajax.JavascriptMethod()]
public bool CheckUsername(String username)

but in my own javascript, when I called "CheckUsername", it was told to be not defined.

HELP! I'm only one step away from ajax.

# re: AJAX .NET Wrapper DLL Video

Actually, I found out what the problem is..

I have my global.asax code behind file and in the

Application_PreRequestHandlerExecute

I have my custom logic. For some reasons, it causes conflicts with the ajax httphandler. I'm not sure why. Here is what I have in this method.

protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
{
string loginurl = "~"+System.Configuration.ConfigurationSettings.AppSettings["LoginUrl"];
bool showlogin = false;
//objResponse.Write("i'm here "+objRequest.Path);
String url = Request.RawUrl;
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
if (Session["name"] == null)
{
// Not a login page
if (!url.EndsWith("Login.aspx") && !url.EndsWith("Modules/System/Error.aspx"))
{
showlogin = true;
}
}

if(showlogin==true)
{
Response.Redirect(loginurl,true);
}
}

# re: AJAX .NET Wrapper DLL Video

Does anyone have any tips or links to any url's with info on using ajax to upload files?
