Calling Method .net From Classic ASP
Mar 28, 2011
I am new to ASP and ASP.net.I have just started working on a legacy ASP classic project and been given a sample that makes a remote call in ASP.net.Is it possible to call the ASP.net page from ASP?Are you they compatible.My impression so far is that they aren't compatible, but perhaps. I'm wrong.I mean the .net project could be called with parameters and kept seperate I guess?Does anyone have any experience with similar problems or have any tips they can share?

I've a pre-supplied public function in classic asp that creates a hash value - it is pretty complex and I'd rather not convert it to .net if at all possible (mainly as I don't understand half of what it does!) I'm running it under IIS7 on VWD2008 express. How would you call a function in that asp file? do you have to redirect or as it is #included into the asp.net file, is there an eaiser way? At the moment the complier does not spot the function and says it is not declared.

I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?

this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?

I am attempting to call an ASP.NET page from a classic ASP page on the same machine. The ASP page is located in c:inetpubwwwroot. The ASP.NET page is located in C:InetpubwwwrootWebServiceWrapper
Here is the ASP code to call the page:
Dim objHttp, strQuery
set objHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")[code]....
The ASP.NET code, which calls a web service and sets a cookie, works if I call it from the browser directly. However, using the Msxml2.ServerXMLHTTP object, it does not. The cookie is not generated and there is no error. There are no events in Event Viewer.The ASP.NET page was developed in Visual Studio 2005, .NET 2.0. Changing the POST to a GET has not helped.

<span class="folder">
<asp:label ID="lblPlantName" runat="server" Text='<% GetPlantName(item) %>'></asp:label>

I have 2 text boxes inside my aspx page and I want to call the same method func(object sender, EvenArgs ev) on ontextchanged events of these textboxes.I want to parse the text of these textboxes inside this function - now the question is how would func(object sender, EvenArgs ev) know which of the textbox's has called it? I need to know that so that I could then use text property of that textbox to parse it and further process it.Isn't there a thing like sender.equals(textbox1).Or probably is there a way I could pass the text as a string argument to func()? If yes, how and whats the format?I dont want to make two functions separately for ontextchanged events of these textboxes, when the fucntionality of this method remains exactly the same.

I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.
My demo page: http://bit.ly/92RYvq
Below is my code and the order I need it to fire.
[WebMethod]
public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category)

I am working on an add-on component that needs to play nice with other similar add-ons. There is a 3rd party component that decided to implement the functionality a little differently than the default. What I am trying to do is call an overload of a method that only the 3rd party component has, like this:
Select Case True
Case TypeOf provider Is 3rdParty.Provider
result = DirectCast(provider, 3rdParty.Provider).GetNames(method, True)
Case Else
result = provider.GetNames(method)
End Select
Unfortunately, the DLL that contains 3rdParty.Provider is optional, so this code will give compile errors if it is not present. How can I accomplish the same thing but make it safe to run whether the 3rdParty.Provider.dll is present or not?

I have a test web service called: MySimpleService.svc with a method called:GetUserNamesByInitials. below is the Linq to SQL code:
[OperationContract]
public static string GetUserNamesByInitials(string initials)
{
string result = ""; [code]...
what I do is to type the user id in one textbox (TextBox3) and when I press the Tab key the result is shown in another textbox(TextBox4).
The jQuery call works well with other methods that do not call the database, for example using this other web service method it works:
[OperationContract] public string ParameterizedConnectionTest(string word)
{
return string.Format("You entered the word: {0}", word);
}
However with the Linq method it just does not work.

, imagine a Master page that implements IFooMaster with a method
ShowFancyMessagePopupTheBusinessCantLiveWithout(string message);
I am in a page that inherits this master page. Upon a checkbox being unchecekd, I want to show a message to the user that if they save it, they can't re-check the checkbox without some admin action.
I've been given feedback that I can't just use an alert('message'); in javascript because they want the consistent look of these messages.
Next, I tried to make an ajax call via PageMethods (as that's what everything else in this codebase uses) to show a message. My problem lies in this method being static.
[WebMethod]
public static void ShowSuperImportantMessage()
{
if(!checkboxICareAbout.Checked)
((IFooMaster)Master).ShowFancyMessagePopupTheBusinessCantLiveWithout("If you uncheck that thing, you can't recheck it.");
}
Since ShowSuperImportantMessage() is static, I can't access Master from within. The method on the master page looks more or less like this:
public void ShowFancyMessagePopupTheBusinessCantLiveWithout(string message)
{
lblGenericMessage.Text = message;
btnGenericMessageOK.Focus();
upGenericMessage.Update();
mpeGenericMessage.Show();
}
mpeGenericMessage is an ajaxtoolkit:ModalPopupExtender.
upGenericMessage is an update panel.The other 2 are obvious.
Can I do some jQuery kung-fu to show that stuff? I tried, but the solution complained that the controls I tried to refer to by ClientID didn't resolve since they were on the Master page.
quick edit: Before anyone tells me the architecture is a problem, or I shouldn't have put such a thing on a master page, or w/e...
I know the situation is not ideal, but I this is inherited code, and I can't drop it all and rewrite half of their web stack.

I have just started using MVC. I created the MVC application and was playing around with it.When you call the http://localhost/home/Index/ on the sample MVC application the Index method of the controller home gets invoked and the view Index.aspx is displayed and similarly when we call http://localhost/home/About/ then the About method of the Home controller is invoked and the About.aspx page is displayed

I have a number of pages which need to support exporting data to an Excel spreadsheet. I can generate the Excel files just fine, but I'm trying to work out how to abstract this behavior so it's easily reusable from all of the pages where I need it. My current idea is to use a static utility method, as follows:
[Code]....
The click handler where I'm calling SendExcelFile looks like this:
protected void lnkExport_Click(object sender, EventArgs e)
{
List<List<string>> dataList = GatherDataForSpreadsheet();
Utility.SendExcelFile(this, "fileNameForDownload.xlsx", dataList, "MyReports");
}
This code works just fine as an instance method of the calling page. As a static method, though, it doesn't work at all. When I click the button that invokes this, the browser shows the loading animations indefinitely, but never prompts for a file download.
EDIT: If I remove the call to File.Delete() at the end, the method works as expected. Does Response.TransmitFile() do the transfer asynchronously?
EDIT 2: I just needed to call Response.Flush() before I deleted the file.
