Web Forms :: Support Legacy Code Without Access To Compiled Code Behind?
Mar 25, 2011
I have been asked to support a legacy app and I can't get access to the code behind files. I need to add a new feature that gets a list of items from the database on page_load, what way would adding an "in-page" page_load affect the compiled page_load?
I have a page which is using the AJAX Control Toolkit HTML Editor. I have it configured with only the Bold, Italics and Underline buttons. Once the user saves the information, it's stored in a database table. No problems.
I need to change the resulting code so the HTML code can be correctly interepted by a Crystal Reports report. CR doesn't understand the <span> options being created by the HTML editor. So for example, I need to change the
<span style="font-weight: bold">Bold</span> code created by the HTML Editor so it's entered into the database as <b>Bold</b> instead.
I can attempt this in the code behind, but I then also need to replace the </span> with a </b>. This causes an issue because if there are multiple options (e.g. bolded word within an underlined line), then the proper tags won't be closed as they should.
I have a tricky situation. My application got deployed in production. A lable value needs to be changed but the problem is am setting the label value dyanamically from page load of my page. Is there way to change the label value withour redeploying? i can change the logic on codebehind but that requires another deployement which i don't want to do that as it is production.
.aspx file that I would have never even thought to look. It was occuring because of a control(ListView I believe) that had been "completely" commented out using the <!-- --> tags. The text was all green which gave me the re-assuring feeling that this code would not be included in the website. I finally decided to search my entire .aspx page for any occurences of the variable it kept insisting couldn't be "databound" and sure enough it was inside a template of a ListView control that was commented out.
Why we say compiled code in ASP.NET using C# or VB.NET means high performance and in the other side the server controls make the website slower! so if we combine server controls + compiled code the result will be the same as other interpreted technologies, so where is the speed and performance in ASP.NET? From this point of viwe it seems to be the same as others technologies, right?
I recently upgraded my development machine to Windows 7 and have been having a bit of trouble setting up my web services locally in IIS 7.5.
The following error keeps occuring:
parse error message: type 'ClassNameHere' cannot be created.
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/ACCOUNT/AccountService.cs" %>
My compiled app_code.dll is sitting in the /bin directory at the root of my virtual directory and in IIS 5.0 and IIS 6.0 I never experienced any problem like this. To me it seems as if the code from my dlls isnt being loaded or recognized for some reason.
I have web projects build in VS2003/1.1 framework and deployed in a webserver with IIS setting specified to 1.1 framework.lets say project X
I also have another web project which is build with VS2008/2.0. IIS setting - ASP version 2.0 is selected and all pages are assigned to run with 2.0* dlls. Lets say project Y
Now the problem seem to be when I hit project x, sometimes it throws errors like "error BC30456: 'Initialize Culture' is not a member of 'ASP.**"
During troubleshooting this issue, I browsed through 2.0 Temporary ASP.Net files "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files" and found temp files generated for project X. (HUH?)
How/why 1.1 project gets compiled in 2.0 only when it errors out.( or we could put it this way that it errors out every time it gets compiled in 2.0 which it is not supposed to)
I'm confused as to why this is happening when project X has nothing to do with .net 2.0.
Adding this info:
IIS version 6.0
I forgot to mention that project X works 95 percent of the time without any errors under 1.1. This error throws randomly which we could not recreate. The time the project error out is at the same time it gets compiled with 2.0
Does code in an .aspx page (in between <% %> tags) get compiled in a web application or is it treated like markup where you can just change it without recompiling the solution? Does compiling only compile the code behind code in the .cs and designer.cs files ?
I'm working on a new website, written in VB.Net using ASP.NET MVC2, there is a need to call "legacy" VB6 code for various complex bits of business logic. The VB6 is a framework consisting of many dlls and is very stateful, we are pretty much emulating how the framework is used in our client application, ie the application runs (lots of state setup), a user logs on (even more state) and then loads a file (even more state).
I've been provided with a "web service interface framework" to get this up and running for use in the web app, this "web framework" hides the legacy code behind a thin layer running under IIS. The idea being that thread pooling provided by IIS will reduce memory use etc etc. I can't help but believe that the guy who provided this has missed the point, since each instance is so stateful there is no way that a thread pool can work, since once a user logs on using one particular object from the pool, no other object will be capable of servicing that client (since it wont have the state)! Also, adding a web service interface and associated SOAP marshalling is a huge overhead compared to calling the objects directly.
The only way I can think of doing this is either a single legacy interface instance which is used by all clients and blocked by each call until it completes, or a thread per client with each legacy interface object being created in a new thread and living for the life of the client.
None of these is ideal but with the amount of code in question and the prolonged migration programme to .net (2+ years and still stateful) I can't think of an alternative. We run the original client app in a citrix environment for some customers so I expect that it could also run ok with thread per client given a beefy enough server and that the overheads of the framework itself should be lower than when the client app is involved.
I am dynamically creating div tags in my code behind and adding code into the innerHTML property of the div tag and then rendering out the html to replace values inside of a table structure that I have, I then place all the table code onto the page. I want to be able to access the div tags again from the code behind, but can't seem to because well obviously they aren't set to runat="server". Is there any way to do this or to set them so they can runat server.
I have a .aspx page that inherits from a class (Hmp.Web.Lib.HmpWebPage which actually inherits System.Web.UI.Page) . The code behind for my page starts like this.
public partial class FnmMessagesEdit : Hmp.Web.Lib.HmpWebPage
I'm having trouble accessing custom profile properties that I've declared in my web.config using the TableProfileProvider available at [URL] I set everything up according to the instructions but keep receiving an error stating "The type or namespace name 'Profile' could not be found" whenever I refer to the Profile object in my codebehind. My web.config is:
I have a 2 textboxes in a Login View on my Content Page (login.aspx) and Login Button outside of Login View. I want to pass the values of those textboxes to the members of class when user hit Login button.
I have User.cs class which contains TxtLogin and StrLogin.

When I debug the program and enter correct username and password it should show me "Thank you" rather than it is showing me "Enter valid Username and Password".
