I've followed this: http://www.codeproject.com/Articles/19535/NET-COM-Interop-Component-with-Classic-ASP-Part-I & http://bruceburge.com/2009/06/11/sharing-net-libary-dlls-between-asp-classic-and-aspnet/ to use asp.net dll in classic asp.
Step 7 listed in first URL didn't work me hence I followed steps given in second URL to to create installation. It works & can see URL in GAC. Unfortunately, it is not working in classic asp.
I tried "regsvcs" at command prompt but didn't work. have developed using C#
Anybody knows what I'm missing?
Update: I could see component under Component Services. I don't see method name under Interfaces & creating object of component is not working. am getting this error:
Expected end of statement on line:
set obj= server.CreateObject("my_dll_New.Class1");

I created the ASP.NET dll with one function that i need to use in Classic ASP page.
I used the below code for creating object in classic asp page
set PeopleSoft = server.createobject("OPS.PSL")
I am getting the below error while executing
Server object error 'ASP 0177 : 80070002'
Server.CreateObject Failed
I searched in stackoverflow i saw some solution. By enabling the "Make assembly COM-visible" and "Register for COM interop".
Please Help me to come out from this issue
You have to register your DLL first, and if the problem persists, do this:
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\
FeatureControl\FEATURE_IGNORE_ZONES_INITIALIZATION_FAILURE_KB945701
Note If the FEATURE_IGNORE_ZONES_INITIALIZATION_FAILURE_KB945701 subkey does not exist, you must manually create it. If you're using a 64 bit OS, you may need to use HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\ FeatureControl\FEATURE_IGNORE_ZONES_INITIALIZATION_FAILURE_KB945701 instead
Right-click FEATURE_IGNORE_ZONES_INITIALIZATION_FAILURE_KB945701,
point to New, and then click DWORD Value
Type w3wp.exe to name the new registry entry, and then press ENTER.
Right-click w3wp.exe, and then click Modify.
In the Value data box, type 1, and then click OK.
After setting this registry key, a simple app pool restart will apply the change. No longer will your .NET COM components randomly stop working with no real solution except shuffling application pools!
Did you register your dll with regasm.exe on your server ?
http://msdn.microsoft.com/en-us/library/tzat5yw6%28VS.71%29.aspx
I had this problem. When you register .NET COM modules you must use regasm and if you want to call them from applications like IIS you must use /codebase with this command:
regasm yourfilename.dll /codebase
I just had this error appear on a site that had been running perfectly for years. It seems a DLL had somehow become unregistered. It was an unmanaged DLL so I was able to re-register it using regsvr32:
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regsvr32 "C:\path\to\myAssembly.dll"
(Also see the difference between regasm and regsvr32)
On this website :
http://connect.microsoft.com/VisualStudio/feedback/details/294241/kb937143-breaks-asp-to-net-com-interop
They fix the problem with giving read access to IUSR on HKEY_USERS\S-1-5-20\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones.
Run this from the command prompt (replace myassembly.dll with your assembly path):
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe myassembly.dll /codebase
I faced a similar issue and after much research i found the solution ,check if its working for you.
Remote scripting causes tons of errors with different IE versions. If your are passing control from one page to another and creating a new object from there you will get this kind of unable to create object error.
Example:
page x.asp--
function1call()
function2call()
further in page x.asp--
function1call(){
var rs_obj = RSGetASPObject("some-object");
----some other things---
frmPost.action = "someplace.asp";
frmPost.submit();
}
function2call(){
var rs_obj = RSGetASPObject("some-object1"); //you wont be able to create
//this object
----some other things---
}
It seems like the remoteScripting object is not getting initiated . As function1call() calls frmPost.submit().
If you combine these 2 functions it will start to work. I.E
page x.asp--
function1call(){
var rs_obj = RSGetASPObject("some-object");
var rs_obj = RSGetASPObject("some-object1");
----some other things---
frmPost.action = "someplace.asp";
frmPost.submit();
}
There is another reason you might get the error "Server.CreateObject Failed". A COM Visible DLL does not behave the same as a regular .NET DLL when it is being loaded by COM. You can't expect it to load other DLLs that are sitting in the same directory as your DLL, or downloaded through the Nuget package manager. If you want to load other DLLs you have to register them in the global assembly cache (GAC).
see: https://stackoverflow.com/a/23902131/2616170
If the assembly doesn't have a strong name then you won't be able to register it in the GAC.
I have created a new VS2008 ASP.Net Web service project, with the default name WebService1. If I right click on the Service1.asmx file and select 'View in Browser' what are the processes that go on to make this happen? I am asking because I have a situation where when I run this from a visual studio project started in our development shell (which sets up a common build environment) I cannot get the web service to show up in the browser.
It starts the asp.net development server and creates a single file:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\c43ddc22\268ae91b\hash\hash.web
but when I start it from a stand alone project i get a whole slew of files in here:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\edad4eee\d198cf0e\App_Web_defaultwsdlhelpgenerator.aspx.cdcab7d2.vicgkf94.dll
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\edad4eee\d198cf0e\service1.asmx.cdcab7d2.compiled
etc etc
I am trying to debug this but not really getting anywhere. i have inspected the output from VS but the only option I get is for the build output, which is basic and doesn't really contain any information that is useful. I have tried running both versions with DebugView running but no output there either.
I would like to know if there are any log files I could look at, or if anyone has any suggestions on how I might be able to debug what is going wrong here?
For completeness the output I get when it doesn't work is:
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not create type 'WebService1.Service1'.
Source Error:
Line 1:
Source File: /Service1.asmx Line: 1
Version Information: Microsoft .NET Framework Version:2.0.50727.3603; ASP.NET Version:2.0.50727.3082
Ok, not sure that its perfect but I found a resolution to this issue. the problems seems to be that the development shell redirects the <OutputPath> of the projects visual studio is building, and this was causing problems as, although the dependencies of the web service project were being copied into the $(ProjectDir)Bin\ directory, the actual webservice dll itself was not. The solution (workaround?) seems to be to add this to the post build event command line:
xcopy /y "$(TargetPath)" "$(ProjectDir)Bin\"
Then i am able to right click on the .asmx file and select view in browser and everything works as expected.
Hope this might help someone else in the future. or maybe even me in another place and time.
HOw to localize classic asp?
I got something from below link
http://networkprogramming.spaces.live.com/blog/cns!D79966C0BAAE2C7D!379.entry
but when i do that, i am getting error.
Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: 'xmlResx'
/MySite/default.asp, line 14
Make sure you code has access to the Msxml.dll file that is used when calling this line
Set xmlResx=Server.CreateObject("Microsoft.XMLDOM")
It appears you don't have the dll installed XMLDOM, thats why it says object required. Did you register the dll on the server? Are you sure there is XMLDOM available? You were considering to upgrade to .net? If you are going to switch languages switch to PHP... trust me i was a long time Classic ASP guru, and I didn't like php at first, but its a dream come true... everything is free most host include everything... with asp you have to buy a 100+ $ program just to thumbnail images! And xml is built in also...
Hey I am coding using Visual Studio 2003. My program worked fine until I introduced a dll I made using CreateObject.
Code:
Set docs2 = server.CreateObject("DocGetter.Form1")
docs2.GetDocument oXMLDom,numID
It appears to be getting stuck at this code. I've already used regasm to register the dll.
What else could be wrong?
Add a reference to the dll in your project and instantiate the object like this:
Dim docs2 As New DocGetter.Form1()
If that doesn't make sense, then fix it so it does. There's no good reason to use CreateObject in .Net code. (Okay, that's hyperbole. But the principal is sound).
Can you clarify - is this a web app or a client (winform) app? Form1 sounds like a winform. ASP.NET runs at the server, so showing a form would be inappropriate - it would happen at the server, not the client. In short, don't do this!
I also can't see where "stored procedures" figures in this, so I've removed the tag.
What are you trying to do? Options for showing something more complex at the client include:
dhtml
flash
silverlight
clickonce [requires windows client]
ocx [not recommended]
I'd bet money that this function isn't defined with this name and/or parameters.
docs2.GetDocument oXMLDom,numID
But because of the way you're instantiating the object, the compiler has no way of knowing this... I think.
I have a class declared in the App_Code folder. The class contains a public shared method that returns a type Portfolio.
When I try to call this method to initialize an object of type Portfolio in one of the ASCX controls, i get a "Value of type Jaguar.Portfolio cannot be converted to Jaguar.Portfolio" message.
This is a "Website" project. I have tried using CType and DirectCast and I still get the same compilation error when I try to build the site.
I am using the line of code listed below in the code behind file of the ascx control
Dim pObjSvc As Jaguar.Portfolio = ClassName.GetPortfolio
Do you have a webpage or a user control also called Portfolio? You may have a name space collision where it's confused between which Portfolio object to use. If this is the case, you'll need to change the name of the Class/Module or the control's or page's code behind class and you should be all set.
There seems to be someone else with the same problem out there:
ASP Net - value of type "MyNamespace.MyClassName" cannot be converted to "MyNamespace.MyClassName"
I have a ASP.Net application that uses
assemblies from several other
solutions. When testing the
applications on my machine I build all
the referenced assemblies using nmake.
The latest assemblies get placed in a
common directory that is referenced by
my ASP.NET app.
Occasionally I receive the following
error: value of type
"MyNamespace.MyClassName" cannot be
converted to "MyNamespace.MyClassName"
(there are a lot of these for
different classes) when doing a debug
build. I have tried the following with
no luck:
Build the ASP.Net application Rebuild
the ASP.Net application Close VS and
build the ASP.Net application Close
VS.Net as rebuild the asp.Net
application IISreset and build/rebuild
the application
It seems the only thing that works is
if I run nmake to build all my referenced assemblies, I can then
build the ASP.Net application.
Any ideas as to what causes this? Is
there an easier way to fix it?
Sadly, the author of the question did non find a definitive answer. But perhaps it contains a hint which could be helpful to find the solution.
UPDATE: I'm not sure if that is even possible in a ASP.NET website, but maybe you accidentally added a reference to a (temporary) assemmbly of the project itself? That would explain the error. Try also to remove the contents of bin and obj folder.
Just a debugging tip:
Try to rename the Portfolio class and recompile. Maybe there is an old assembly somewhere or some other code in .vb your files which contains a class with the same name?
I have seen situations similar to this when an aspx page was created with the same name as a business object class. Do you have some some aspx page with a code-behind class of Portfolio as well?
