View 2 RepliesI have an ASP.NET website that uses Forms authentication
<authentication mode="Forms">
<forms name="NewsCoreAuthentication" loginUrl="~/Default.aspx" defaultUrl="~/Default.aspx" protection="Validation" timeout="300" domain="someRootDomain.com" />
</authentication>
I need to identify if user is authenticated on web page after it was rendered to client. To accomplish this I thought that I can read document.cookie and check if ".ASPXAUTH" is there. But the problem is that even if I am signed in this value is empty.
How can I check that user is authenticated? Why document.cookie is empty?
Is there a way to show CPU and RAM usage statistics on an asp.net page. I've tried this code but I have error:
Access to the registry key 'Global' is denied.
on this line:
ramCounter = new PerformanceCounter("Memory", "Available MBytes");
I hosted a webservice in my Windows7 machine. and i got the exception as given:
Exception Details: System.UnauthorizedAccessException: Access to the registry key 'Global' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
Even after i have given permission as Everyone the above issue still eexist..
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.
What changes & where do i make in webconfig??
I am trying to add a client side event to a dropdownlist and I need to access the currently selected Text. I have tried:
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text.Equals(' UNASSIGNED');");
and
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.text.Equals(' UNASSIGNED');");
Both of which give me runtime errors when the event is fired.Whats the correct way to access this text property client side?I tried this but it does not enable the checkbox...
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text == ' UNASSIGNED';");
ANSWER:
Well, along with having to use == rather than .Equals, when you set a checkbox.enabled = false on the server side it raps the checkbox in tags and sets it to disabled=true; therefore you must set BOTH the checkbox.disabled = false and checkbox.parentElement.disabled = false; on the client side to enable the checkbox!The solution:
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').parentElement.disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED'); document.getElementById('" + chk_techreview.ClientID + "').disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED');");
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.

View 1 RepliesI want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles:Can I call onclick event on client side otherwise on server side?the statement table.onclick=SelectRow(event) fires a bug!Code:

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

View 3 RepliesI have a really strange issue. I'm using the following code to retrieve the current user name from the registry:

For some reason it isn't returning the actual value stored. Instead of returning something like CSS it's returning administrator everytime.
I have a Library ( DLL ) that has a method with the following:
var masterKey =
Registry.
LocalMachine.
OpenSubKey("SOFTWARE\Microsoft\Dynamics\5.0\");
When running this method in an WinForms applicaiton, masterKey is not null and when running this in asp.net masterKey is null!
I've checked the executing user with WindowsIdentity.GetCurrent().Name and the same user is executing both applications. The asp.net application is executed in visual studio ( debug: F5 ) and so is the WinForms application. I've set the permissions to none what so ever and this gives me "Access Denied". And when I add the group Users I get null. Which would mean that I can fold up the strucutre and see that it's there, but I cannot access the keys/entried.
it should be in asp.net. but, it is urgent and important, wish someone here know the answer.
what I need do for an asp.net page is:
1) client select a file, or;
2) client select a folder;
Get file (or files in the folder)'s properties, something like name, ext, etc. and save to db.
it will be easy if it is a desktop app. however, in asp.net, how can I do that? do I have to upload all files to server first? is there a way to do this for all files in a folder? any third party control?

View 1 RepliesI want to be able to provide a list of files on an ASP.Net page which link to files on the users shared drives.
When the user clicks the link they can modify the file and then save it back to the shared drive.
An example would be:
<a href="file://M: estBook1.xls">M: estBook1.xls</a>
However this does not work, even from a trusted site.
I can understand the security implications but these can be managed.
how can i access client machine's specific file contained in a drive or folder.Suppose in Server side i have knowledge of full path of a file that is present in client side, like "D:ABCFolderxyzFile.doc", this is a file that i want to retrieve and store in server side .
