for this i can create a libaray and do it ..many different libarray for many people with interface inclued in all ..this is want i need to do ...but the problem for me s i dont know wat library he s going to give me .. client will give me only the dll and i hv find the class name and its corresponding custom sectipon and call the interface method and get the output ..Reflection s the way but i dont know how to do it ...
I have an ASP.NET website and I want to find the /bin/[Configuration] folder to use an external tool (an exe file). When I use reflection to get calling assemblies location it returns something similar to:
C:WindowsMicrosoft.NETFramework\...Temporary ASP.NET Filesa1388a5e\...my.dll
Since each dll has its own directory under the temp ASP.NET Files this fails for me. How can I get the location of the compiled binary folder where the dll's and the .exe is (i.e. bin/) instead of asp.net's temporary cache?
I have an ASP.NET web app and am attempting to reference an external config (using enterprise application blocks configuration) for some of the configuration but it is not entirely working. I previously had all of the configuration info in the web.config (and it was working), but we are wanting to share some of this configuration information between multiple apps. When I put configurationSource tag in the web.config, and read the configuration through the WebConfigurationManager object, it loads some of the external config info (Logging) but not the connectionStrings and not the custom section I created. So it's reading it (logging is working), but some dots aren't being connected and my connection strings aren't coming through.
Again, it worked when it was all in the web.config. I am running .NET 3.5. Any idea what needs to change to be able to reference an external configuration source and have it all come through?
It's been so long since I've done this that I don't remember how.
Basically, I am creating a Web Application from scratch. I have dragged the LoginBox to the page and went to "Administer Website". Unfortunatel I see no where where I can choose to have the application talk to an externally-hosted database as opposed to defaulting to the "App_Data" folder. I am hosting an SQL instance named "SQLEPXRESS" on my development machine and have configured a database and user. I wish for the site to use this database and user and have set the connectionstring as follows in the web.config:
Yet even after adding that I see it showing no where in the "Administer Website" section. Please walk me through getting my application to talk to this database and configuring the necessary tables. I remember there needing to be some sort of exe I needed to run to do this, but my Google and forum searching is failing me.
I have a simple webApplication. Now I have a second webapplication with few web aspx pages. When I build each project I get aspx files with 1 dll per project.
Now the structure of the first webApplication is like this
inwebapplication1.dll
Default.aspx
Is it possible to load the dll of the second application dynamically and put its dll into the bin directory. The result will be something like this:
inwebapplication1.dll
inwebapplication2.dll
Default.aspx
application2default.aspx
The problem is that when I try to open application2default.aspx the compiler is throwing an error that it cannot find the class for that particular page because the assembly inwebapplication2.dll is not loaded. I tried to load the assembly from the web config like this <add assembly="myassemly, Version=1.0.0.0, PublicKeyToken=null, Culture=neutral"/> and also from the code like this Assembly.LoadFrom( @"D:Projectsinmyassemly.dll" ); OR Assembly.Load( "myassemly, Version=1.0.0.0, PublicKeyToken=null, Culture=neutral" ); but I still have no success. Can u tell me what is the logic here with the assembly load?
Using Visual Studio 2010 Web Developer Express (vb.net code) with SqlDataSource to SQL Server 2008.
I am developing an email form to my users to send email to vendors with an attachment. The aspx page is quite simple -- 2 dropdownlists, a fileupload control, and a send email button. They select their store (which populates the "From" address of the email). They select the Vendor (which populates the "To" address of the email). Then they browse for the file attachment and click "send email"
I just can't get outside emails to send. I do not get any error messages in the web page. If I change the email1 and email2 in SQL Server Vendor table to an email address (mine) within the domain I get the emails. However when I change to a test hotmail, yahoo, or gmail accounts the emails never get there. I have absolutely no confidence that my programming is correct so before I go to the IT Manager again I really need to verify I am not missing something on my end. We did make a change on the exchange server to allow anonymous email from my webserver and still didn't work.
Here is my webconfig file:
[Code]....
Here is my code-behind:
[Code]....
Here is my aspx page:
[Code]....
I have been playing around with the programming for 2 days making 1 change at a time then testing to see if external email is sending. I'm going quite crazy at this point ...
I've put in breakpoints and debugged. Below is the output from the latest test. I have concerns about the clientDomain being "SQLSVR" which is my webserver name, our domain is "chuckanddons.com". As well as the line "Domain" that is blank " " under NetworkCredential. Also the line TargetName "SMTPSVC/exchangesvr"
I am trying to come up with the best way to get only certain properties from a type using reflection. How can I differentiate the properties from each other?
I understand that I can use binding flags or name. But say I want only a certain four properties. Would the best way be to create a custom attribute for the ones I want then loop through all of the properties to see if they have that attribute?
I have a class decorated with a attribute ...[DataEntity("MESSAGE_STAGING", EnableCaching = true, CacheTimeout = 43200)] for some requirement,I want to change this value "MESSAGE_STAGING" at run time to "Test_Message_Staging". What is the best possible way to achieve this? Can i use reflection ,Or is there any other way to do this.
I have a collection of assemblies using reflection. I want to loop through them, but I would like to ignore the .NET framework or ASP.NET framework DLL's. Is there an attribute on the assembly that marks that its from the .NET framework? Or any other designation?
I was looking at the name, and if the name of the assembly starts with System, Microsoft, or mscorlib, I am ignoring it. But I was wondering if there is a flag I can use to make this even easier?
I got a strange one here and I want to know if any of you have ever run accross anything like it.
So I've got this web app that loads up a bunch of dll's through reflection. Basically it looks for Types that are derived from certain abstract types and adds them to the list of things it can make.
Here's the weird part. While developing there is never a problem. When installing it, there is never a problem to start with. Then, at a seemingly random time, the application breaks while trying to find all the types. I've had 2 sites sitting side by side and one worked while the other did not, and they were configured exactly(and I mean exactly) the same.
IISRESET's never helped, but this did:
I simply moved all the dll's out of the bin directory then moved them back. That's right I just moved them out of the bin directory then put them right back where they came from and everything worked fine.
Any ideas?
Got some more info
When the site is working I notice this behavior: After IISRESET it still works, but recycling the app pool will cause it to break.
When the site is broken: Neiter IISRESET nor recycling the app pool fixes it, but moving a single dll out then back in fixes it.
Even More Info
So it turns out that IsAssignableFrom is not returning the correct value. I would not have believed it to be true, but I had my logger log the result and the 2 types, and it definitely returned the wrong value. The crazy thing is that the same dll will return different values at different times when comparing the same 2 types. Yet More Info The particular class that IsAssignableFrom fails on in located in a file with other classes. If I move the class to its own file, then everything works fine. However, if it is in the same file as other classes(even if it is in its own namespace block) then the Type reference is all wrong. The Type reference will have the correct name and methods, but it has trouble finding the correct constructor.
I am trying to create instance of class by using reflection in ASP.net web site. Class ClassName is defined and located in App_code folder. Following line returns null, what could be wrong.
Type type = Type.GetType("NameSpace.ClassName", false, true);
How can I create an instance of a web control at runtime using reflection? I created a series of controls that implement a common interface and I would like to create these controls based on the name of the control which is stored in my database.
I have attempted (and failed) to create an instance of these controls using Activator.CreateInstance in the following ways:
given a url that references an asmx how would i go about displaying all of their method names? if assembly="http://.../something/something.asmx" and i was trying to display the method names of that service what should i do now that i have gotten myself this far? i cant seem to find a solution among the hundreds of examples ive looked at
public TestReflection(string assembly) { Assembly testAssembly = Assembly.LoadFrom(assembly);[code]....
I have a function that at the moment takes a Type variable. This function sticks it in a list and such and eventually needs will create a class of that type. Right now I do that with
which is pretty hacky and also will not work in medium trust due to reflection(I think). Is there a better way of doing this without reflection? The Type is defined this way as part of a function. I need the class to be created "lazily" because it may not be created in the application if it's not needed. I use it for example like
AddToList(typeof(Whatever));
Note, I'm open to suggestions on changing the function calling. I just need the object to be created lazily and for to store the type(or however to create an object of the type) in a list.
I've been tinkering for hours and I can't figure this out. Seems like it should be pretty straight-forward. Is it possible to use reflection to get a reference to a partial page class given the page's name and path so that I can iterate through the page and examine its controls? I am not looking to examine the currently loaded page, but another page within the same website.
I have a UserControl which contains a TextBox and a CustomValidator. I would like to set the CustomValidator.ServerValidate to a method in the page that contains the UserControl I found this code which will allow me to dynamically set the custom validators validation function: cusvCustom.ServerValidate += new System.Web.UI.WebControls.ServerValidateEventHandler(MethodName);
The problem is that a string value won't work there. It needs to be a reference to the method. Is it possible to use reflection (or some other method) to get a valid reference to the parent controls method using only the string name of it? The reason I want to use the string value of the method name is so I can place the control on the page thusly: <uc1:TextBoxField ID="tbUserName" runat="server" CustomValidationMethod="ValidateUserName" />
WebUserControl.ascx <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl.ascx.cs" Inherits="WebApplication1.WebUserControl" %> <asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Custom Validation Failed" OnServerValidate="CustomValidator1_ServerValidate" /> <asp:TextBox ID="TextBox1" runat="server" /> <asp:Button ID="Button1" runat="server" Text="Submit" CausesValidation="true" /> WebUsecControl.ascx.cs using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication1 { public partial class WebUserControl : System.Web.UI.UserControl { public ServerValidateEventHandler Validating; protected void CustomValidator1_ServerValidate(object sender, ServerValidateEventArgs e) { if (Validating != null) Validating(sender, e); } } } TestPage.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestPage.aspx.cs" Inherits="WebApplication1.TestPage" %> <%@ Register Src="~/WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <uc1:WebUserControl ID="WebUserControl1" runat="server" OnValidating="WebUserControl1_Validating" /> </div> </form> </body> </html> TestPage.aspx.cs using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication1 { public partial class TestPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //WebUserControl1.Validating += WebUserControl1_Validating; } protected void WebUserControl1_Validating(Object sender, ServerValidateEventArgs e) { e.IsValid = false; } } }
I did some research and I found Type.GetMethod and MethodInfo but I can't get them to work. Primarily because I don't know the type of the parent control and can't figure out how to get it. EDIT: My code for matt-dot-net. As you can see it's almost an exact duplicate of your code. For whatever reason it does not work for me as I have it here. When I click on the button the page reloads and is the same. When I un-comment the one line though and click the button then I see the error message.
I want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll") assembly = System.Reflection.Assembly.LoadFile(assemblyName) assembly.GetType("myClass").Getmethods(Bindings.NonPublic) assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
I am trying to set property value using reflection as below. I wanted to know if there is any generic way of finding the property type instead of doing it int he below way.
I am populating a page with controls reading properties of a class using reflection. If the property type is 'String' I will add a text-box. If the property type is enum I am adding a dropdownlist. Now I have to populate the dropdown options with enums. How can this be done?
Both the enum definition class(Assignment) and the class(classOne) using which I am populating the page with controls are in the same Namespace(MySolution.Data). While looping through classOne properties when the property name is 'SkillLevel' I will have to go to assignment class get the members of enum SkillLevelEnum and populate the dropdown.
Same needs to be done for other dropdowns also.
My Code:
namespace MySolution.Data { public class classOne : MyAdapter { private string _Model;
