I have tried with your code and it is working fine. What exact problem you are facing? Try to put a breakpoint and debug it.

Hi
I have an update panel that surrounds a wizard control which I use in conjunction with a update progress control. Now my update progress control works perfectly, with my animated gif and div tag that lays over my wizard control when the user goes from step to step. However, there is a problem that I am struggling to solve. A number of my steps use controls like list boxes, and when the update progress control fires, the list control is not laying underneath my div an animated gif no matter how high a make my css z-index on the div.
Does anyone have a way of solving this?
Thanks

Hi,
(Firstly, apologies if this is not the best forum for this question, but I couldn't see one that looked better suited.)
Does anyone know of a good, easy-to-use tool for automated testing of websites - preferably free or low-cost?
One I have tried which is particularly good but I cannot currently afford is WAPT. This allows you to use a standard browser to record a sequence of actions on a website and then allows you to simulated many users running the same (or a different) script. The reports at the end of all this show errors and other statistics (e.g. average page load times).
My ideal would be something as close to this as possible (in fact, does anyone have an older version of WAPT to sell?).
Any suggestions would be very gratefully received.
Best wishes, Patrick

I've got multiple date fields on a form in asp.net. I've been asked if there's a way to have a shortcut key (e.g. Ctl+semicolon) to fill the field with the current date. But, I don't want the fields to default to the current date, because many times the fields are left empty. Anybody got an example of code without buying Beans or some other outside software?
Thanks,
JB

Thanks, Yusef, I'll take a look. The url supplied was a "not found" - maybe a typo? Could you redo, please? Thanks!

Thanks Yusef - looks like it might be putting me on the right track. Appreciate your time.

Does it have to be a shortcut key? That would be a little tricky to set up in a way that is truly cross-browser, cross-OS compatible, but it would be pretty easy to have a clickable image (or text) next to each box that would do this using JavaScript.
|
|
|
|
|
Interesting idea. Got an example anywhere? Might be a good idea.
|
|

well, use a JS function such as:
function setNow(txt) {
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
document.getElementById(txt).value = curr_date + "-" + curr_month + "-" + curr_year;
}
and then call it from whatever textboxes you want like this:
<input type="textbox" id="box1" /> <a href="#" onclick="setNow('box1')">today</a>

Thanks, NeverHeardOfMe. Doesn't work for me to only use javascript and change my textboxes to non-asp.net textboxes. I'm going to have multiple date asp.net textboxes on the page, and within any of the textboxes, I need to be able to call the shortcut to render the current date, so if they could be asp.net textboxes, your code would work. But, I need the functionality of the asp.net textbox. I tried to get the text of the asp.net textbox to be a hyperlink, but it renders the text literally today. If I could get around that, it'd be wondermous. Any ideas?
|

|

NeverHeardOfMe - found it! This works: <asp:textbox id="mytext" runat="server" onclick="setNow('myText');"> Thanks so much for pointing me in the right direction.

Well, posh. Almost there. The textboxes are actually in a gridview, footer and edit rows. So, I tried this in the textbox on the footer row as a test: onClick="setNow(this);" and it didn't work. So I tried putting name="textBoxName" as well as id="textBoxName" on the control. Didn't work. Know of a way around this so that the javascript can get the correct argument? Thanks.

You need to do it all in the RowDataBound event - find the textbox and use its ClientID property as the argument for your function call - which you will also have to build dynamivally in the same place.

I have a application that is running live , I want to run the application on my local system so that some changes can be made.
I am attempting to use the Enterprise Library Cryptography block to encrypt a credit password in my ASP.NET 3.5 application. Everything is configured correctly,and not getting any error when I build he application but When I call the DecryptSymmetric () method, I get this error:
The system configuration source is not defined in the configuration file.
[System.Configuration.ConfigurationErrorsException] = {"The system configuration source is not defined in the configuration file."}
Stack trace:

pz let me know What is the solution of the above issue. I am searching it on google from last 4-5 hrs but did not get any solution , please let me know if any body have any other finding or anything I have missed .

Are you sure entlib.config is in the right folder and that it is formatted correctly with all of the required info? The first google hit[^] when searching for your error shows an example with all three files, but you only show two.

I have changed only ProtectionKeyFilename in entlib.config section
like this
<securitycryptographyconfiguration>
<symmetriccryptoproviders>
<add algorithmtype="System.Security.Cryptography.RijndaelManaged, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

I am not analyzed that what changes i have to do? can u pz tell me what other more chages i will have to make in my application.

Hi
I have a wizard, which contains a series of custom user controls as steps. Also I am using the step navigation template to add in the navigation buttons.
However, due to some steps needing a little time to load fully due to web service calls and having to add some dynamic steps, I would like to disable the navigation buttons until the next step has been loaded and change the text on the "Next Button" to "loading...". Is there away I can do this perhaps with JavaScript or is there away I could do this with an AJAX control? If so, does anyone have an example I could use?
Thanks

I am using version 3.1 of Enterprise Libraries and used the EntLibConfig app to configure my logging options. I set it up to send me an email if an exception occurs.
I am doing this to allow Ent Lib to handle the exception:
bool rethrow = ExceptionPolicy.HandleException(ex, "Clerical Exception Policy");<br />
<br />
if (rethrow)<br />
throw ex;<br />
What I get is an error coming back saying 'Logon failure: unknown user name or bad password'
The exception appears to be when it calls GetExceptionPolicy.
However, I am not doing anything, or shouldn't be doing anything, that requires a username and password. Inside the EntLibConfig application I set the 'RequirePermission' flag to False under the Exception Handling section.
Any idea's what could be causing this? I did try using impersonation inside my web.config and no luck. Thought maybe the ASP.Net account didn't have permission to do something.
Thanks.

Hi,
In old style i used to return datasets to BOL (From DAL) and then to Website. but in 3.5 is there any new way to construct DAL. i heard about returning List<> is better than DataSet. Please suggest me which is the best way.
I Got to build new DAL for my new project. if i should go for List <> aprroach can i use Linq to Sql technique or shall i go for execute dataset (using applicatio block libraries) and then fill data in List<> prior to return it back to BOL.
Thanks

I voted this as a bad question not because it is a bad question but because it is not a good one. Some one keeps marking questions as good when they are, in-fact, neither good nor bad.
There are a lot of ways to construct a DAL and there are many tools which will purport to do all of the work for you. However, there is one thing none of those tools will do and that is help you to understand the business requirements. Time and again I see duplicated and wasted effort from DAL Generator based systems because no one took the time to ask why, knowing, it is trivial to rewrite the DAL.
Personally, I prefer hand coding, if for no other reason that it forces me to understand the object graph that is being constructed and to choose the most effective manner for doing so without fighting a tool-kit. Write your DAL yourself and you will learn a lot. 3.5 makes it really easy with automatic properties.
Below is a quick sample, it is real easy and there is no magic anywhere. Any developer should be able to figure this out:
public class Customers : List<Customer>{}
public class Customer : IEntity{
public Int32? Id{get;set;}
public string Name{get;set;}
public DateTime CreateDate{get;set;}
internal static Customer Create(SqlDataReader reader){...}
}

Some of the most common reasons people give for using List<T> instead of datasets are:
Datasets are big and come with a lot of overhead.
Datasets are subject to more runtime errors due to data type issues.
List<T> gives you access to all sorts of cool extension methods in Linq which are also compile time checked versus using sql filters on datasets which are runtime checked.
You could jump straight to 4.0 instead of 3.5 and use Entity Framework[^].

Once upon a time I lived in hope that someone somewhere could show me the correct way to structure an application and pass data between the layers.
I gave up, because there is no right way.
There is virtually no point in trying to figure out whether it's better to pass around DataSets, Lists, XML, or some other representation of your data.
You would not only have to figure out the verious pros and cons of each method, you'd be confused into a stupor by trying to seperate facts from the quasi-religious views of the very "experts" that would be offering to reveal the facts.
So. Forget for one second that there are Datasets and Lists etc. Figure out what constraints are in place, then figure out what service you're Data Layer needs to perform and then work from there.
For example...NHibernate is cool, but If your organisation won't let you install NHibernate then NHibernate is out immediately. Simples.
Next try and figure out as many different ways of moving data around that fit within your constraints. Actually build a few vertical slices of applications. You'll learn more from doing this that from reading 100 pro/con articles.
DataSets have some powerfull features for tracking changes to data. DataSets are also wonderfully simple to bind to.
If you code custom business objects and pass around lists, are you prepared to do the work necessary to replicate that functionality? Do you even need to replicate it?
Is your DataLayer adding any value. I can't count the number of times I've seen Business Layer Objects that pass their data to a Data Layer Object that do nothing more than pass the same data through to the Database.
This might be worthwhile if there was a potential for swapping out the Data layer, but that's so rarely the case.
Of late I have become very fond of domain objects that are completely ignorant of the database. There is no DB logic in there at all. The domain objects don't even know about the Data Layer objects.
I don't really care about DataSets, Lists, XML, NHibernate etc. Those are implementation details, the big issue is the persistence ignorance.
That's not to say that persistence ignorance is always the way to go. The project I'm working on right now doesn't use it because I'm working within contraints that were already in place when I arrived. And that's fine.
Worrying about Datasets vs Lists without knowing the big picture is like obsessing over a Sedan or an SUV even though you have no idea where you'll be driving or how many passengers you'll have.
If I could sum up my philosophy on this I would say the following:
Build Apps using the simplest solution possible until you know enough to justify why a more complicated solution gives enough long term advantages to justify itself.
If someone doesn't know whether they should use DataSets or not then they should use DataSets until they figure out why they shouldn't.
Hope that helps.
