Web Forms :: Developed An Error In A Web Application That Uses The Progstudios.webcontrols.combobox?

Mar 23, 2010

I have developed an error in a web application that uses the progstudios.webcontrols.combobox (asp.net 1.1) The strange thin is that I have at least 20 back up copies of the same application taken over the years and they all now give the same error, so I can rule out an accidental code change.The error is -

Overload resolution failed because no accessible 'LoadListControl' can be called with these arguments:
'Public Shared Overloads Sub LoadListControl(ddl As ProgStudios.WebControls.ComboBox, ddlSource As Object)': Value of type 'ProgStudios.WebControls.ComboBox' cannot be converted to 'ProgStudios.WebControls.ComboBox'.
'Public Shared Overloads Sub LoadListControl(ddl As System.Web.UI.WebControls.ListControl, ddlSource As Object)': Value of type 'ProgStudios.WebControls.ComboBox' cannot be converted to 'System.Web.UI.WebControls.ListControl'.

Developed A 3.5 X64 Web Application That Includes A Custom HttpHandler?

Mar 22, 2011

I developed a .Net 3.5 x64 web application that includes a custom HttpHandler in the config:

<add path="*.class1" verb="GET" type="ClassLibrary1.Class1Handler"/>

This works when the platform target for ClassLibrary1 is set at x86.
However, when I set this to x64 I get the following error when I run web application starts (it compiles just fine): Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load file or assembly 'ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.


Does this mean that a HttpHandler can be compiled at x86 only?That doesn't make much sense to me.Does anyone have an idea of what could be going on?Edit 1:The ClassLibrary1 project is just an empty class library project with a single HttpHandler added (which is also empty).Edit 2:I am also getting these warning messages when compiling, I am pretty sure they have something to do with this problem: Assembly generation -- Referenced assembly 'mscorlib.dll' targets a different processor HttpTestEdit 3:I manually edited the project file to force references to the x64 assemblies, like this:

<Reference Include="$(Windir)Microsoft.NETFramework64v2.0.50727System.dll"/>

This does supress the above warning message, but the problem isn't resolved.

Developed .NET MVC Web Application To Execute PowerShell Scripts?

Apr 16, 2010

I have developed an ASP.NET MVC Web Application to execute PowerShell scripts.I am using the VS web server and can execute scripts fine. However, a requirement is that users are able to execute scripts against AD to perform actions that their own user accounts are not allowed to do.Therefore I am using impersonation to switch the identity before creating the PowerShell runspace:

Runspace runspace = RunspaceFactory.CreateRunspace(config);
var currentuser = WindowsIdentity.GetCurrent().Name;
if (runspace.RunspaceStateInfo.State == RunspaceState.BeforeOpen) {
runspace.Open();
}

I have tested using a domain admin account and I get the following exception when calling runspace.Open():

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Requested registry access is not allowed.

The web application is running in full trust and I have explicitly added the account I am using for impersonation to the local administrators group of the machine (even though the domain admins group was already there).I'm using advapi32.dll LogonUser call to perform the impersonation in a similar way to this post (http://blogs.msdn.com/webdav_101/archive/2008/09/25/howto-calling-exchange-powershell-from-an-impersonated-thead.aspx)

Web Forms :: Handling TreeView Error Detected By System.Web.UI.WebControls.TreeView.LoadPostData?

Mar 1, 2011

Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

Message: Input string was not in a correct format.

Stack Trace:

AJAX :: ComboBox Input / Whenleave The Combobox It Adds To The Combox List?

Dec 3, 2010

I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).

I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

VS 2010 - When Selecting Default Option For Combobox 1 / Second Combobox Is Disabled

Jun 13, 2012

I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.
