hi, i don't know if this is the correct forum if not please transfer it to the correct one.
i have a question how to handle userrights.
at the moment i wanna make for my page userrights which menupoints the user can see. i don't use the asp.net membership provider. i have a user table , a role table a rolegroups table and a userright table.

when a user is logged in i look in the userrights table (from my masterpage where the menulinks are created) which menupoints the user can see (for example the user1 is in the group visitor1 he can see link1,link2, link3)

user2 is in the group visitor2 he can see link2 and link3

what are the best way to handle this ? because my solution is very slow. specially how can i use session variables or is there an effectiv solution

Why is it so slow ? Perhaps you need to reengineer it ? How are you generating menus ? I'd think if the menu never changes,. you could indeed generate it once, then store it somewhere. Or if it takes a long time to generate, you could generate it and store it so that you can just pull it from your DB, for example, without having to do the calculations every time.

By using javascript also you can set the access for different user's

Handler to write image from DB not working IE7

I have an .ashx file that loads an image (specified by id in querystring) and then writes it out to the client. This works perfectly in Firefox, but all I get is a red X in IE7 (I have no way to test IE6). Here is the method:

<br />
public void ProcessRequest(HttpContext context)<br />
{<br />
	int contribId = Convert.ToInt32(context.Request.QueryString["id"]);<br />
	byte[] buffer = Contributor.GetImage(contribId);<br />
<br />
	context.Response.ContentType = "image/jpeg";<br />
	context.Response.BinaryWrite(buffer);<br />
}<br />

Any idea what is wrong with this?

you could try

public void ProcessRequest(HttpContext context)
{
int contribId = Convert.ToInt32(context.Request.QueryString["id"]);
byte[] buffer = Contributor.GetImage(contribId);

context.Response.ClearContent();
context.Response.ClearHeaders();

context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(buffer);

context.Response.End;
}

I didn't get any requirements for the signature

Ok, so come to discover that there was some issue with the image itself and Firefox could display it, but IE could not.

Thanks for you suggestion though.

What is the problem with DNN ? which version of DNN are you using ? How did you start to build a web site using DNN ?
However, I think the main problem concern is your Data Base. Only the SQL Server data provider comes default with the installation of DNN. For MySQL you have to cutomize the code. you can check this like[^] for mysql provider.
But why are you going for Mysql ?

PDF without Plug-In

Is there a control I can embed in a page that will allow my user to view and print a PDF file, without requiring the installation of browser-plugin?

Re: PDF without Plug-In

Brian W King17-Mar-09 4:52

No. Either way, you have to have a control that needs to be downloaded via the browser (such as Active X) or the client must have a locally installed a PDF viewer.

A PDF cannot be re-rendered in anything else without losing formatting and hence losing your ability to print a controlled format document(such as is a PDF). If you could give a stink about formatting, layering or built-in functionality, then convert it prior to viewing, otherwise you are stuck.

You can achieve something like this by converting the pdf into HTML at server and display it to the browser.

If it's a particular PDF available on your server (or they are going to upload it first) then you could convert teh PDF to 'some other format' either HTML or image, and then they could print it from their browser without a plug in - but it's unlikely to look pretty.

Hi,

While working with SSRS programmatically using C# , ASP.Net 2.0 , the web page is loaded with report from the report server and the issue is with the link buttons and + / - ( Drilldown ) , by clicking on these button its url pointing to the actual report server, thus giving an parameter error. So my wish is to disable all those button's urls. Any idea to get this done , that would be great to me. Thanks in advance.

Seriously, is there anything in Sql Server Reporting Services documentation how to do this? Why are you getting an error? Try to figure out the source of the issue, rather than simply disabling it.

You can use For XML Auto in SQL Server SP's to return XML. and for return XML from web methods, check HOW TO: Use XmlDocument Elements When Passed to or Returned from WebMethods by Using Visual C# .NET[^]

hi all,

I have tried following codes :-

window.opener.location.reload(true);
and
window.opener.document.forms[0].submit();

these are working for normal popup but doesnot work for showmodaldialog() method and it displays an Javascript error that cannot find object.

How will I refresh my grid, which is in parent page and within a update pannel,when I will click on the close button of the chield page the chield page(showmodaldialog()) should close and the parent grid should refreshed with the changed data.

-----------------------------------------
window.opener.location.reload(true);

for a 'normal' window, but this doesn't work for showModalDialog. It is
modal as far as the client is concerned but not the server...

In my app I have a datagrid on the main aspx page, I pop up a modal dialog
to edit a record. On closing the modal dialog I'd like to refresh the
datagrid with the new data.

----------------------------------------------
Please help!!!!!!!!!!!!!!

Thanks and Regards

use the mark up below.

<a href='javascript:void(window.showModalDialog(''HRComments.aspx?CID=
<%# DataBinder.Eval(Container.DataItem, "DB_CANDT_ID")%>
&QStringCandtName=<%# DataBinder.Eval(Container.DataItem, "CandidateName")%>''
,null,''dialogHeight:12em;dialogWidth:15em;status:no;scrolling:no''));'
onmouseover="Javascript:abc();">Comments</a>

---------------
Basically problem was due to the intermingling of single and double quotes.
What you need to do is use single quotes for begin/end strings in javascript and if there is any single quote inside a javascript string itself put two single quotes ('') as i have used above.
e.g. ... showModalDialog(''HRComments...
in above line of html there are two single quotes and not a double quote.

And the double quotes should be used only within sever tags.
I hope that helps.

s.a.w.
