Re: Help me in username and password validation through accessing the database

firstly i would use the membership provider given with .net framework2 and VS2005.
Then you can create the tables and everything needed in the database using the aspnet_regsql program that comes with the .net framework (it is in the framework folder on your pc just do a search).
Then you can use webconfig to put your provider information and use the login tools etc with little or no code on your behalf.

Re: ASP Redirect on Session Timeout

if you use a javascript timer and keep a reference to it in javascript you can run client side code on your controls to reset the timer if they make a keypress.

var timer = setTimeout(redirectfunction,600000);
redirectfunction
{
.....
}
function resetTimer()
{
clearTimer(timer);
 setTimeout(redirectfunction,600000);
}

<html code>
....
<input type="text" onblur="resetTimer()">...etc.

Re: Database Connection in Visual Studio 2005

to get the grid view to display the data then just bind the datasource you created to the grid (you can do it in the form designer in VS2005
To protect it so only logged in people can see it, either protect the whole page (use webconfig to protect different areas of your site) or use a login view control and place the grid in the logged in view.

Re: ASP Redirect on Session Timeout

the easiest way is to put a response.redirect in the header of the page with the delay set to the same timeout (10 minutes in your case). Everytime the page loads after 10 minutes it will redirect the user to the page.
If the user submits something and refreshes the page it will start again as the page reloads (be careful if using ajax though!).
The other way is to use a timer to do the same thing.
The third and the best but also the more complex way is to use ajax and server callbacks.

Re: is it possible to create Animation using asp.net

either flash or an animated gif if it is nice and simple. an animated gif is a series of "still" gifs put together one after the other and played fast (just as a normal movie is created). No extra tools are needed by the end user then - just a normal img tag will display it.

Re: error on page!! Cannot solve!!Help

the problem is because you deleted the form in your html code. You have no form therefore you cant postback to the server.
As you have no form the postback script you hightlighted couldnt find the form so couldnt get the viewstate.
Why did you delete it?
You have to have a form to have asp pages.

Re: need help with sql database in asp.net using VB

use the formview control and bind it to a datasource control which is configured to access your database.
If you use VS2005 they are there and very simple to setup (follow the wizards). Drop a form view onto your page, where it says datasource use the drop down to make a new one and follow the wizard to configure the datasource to do selects, updates, inserts and deletes to your database.

When it is all done and working properly you will be able to see the code it created and understand what it did and then you can roll your own at any time.

The datasource is a powerful tool, especially the object datasource if you are using multi tier applications

Re: Making ASP.Net pages better looking

css css and more css!
your asp.net web sites should be split into 4 areas - the aspx page with just html (just what needs to be in the browser), the aspx.vb or cs code behind file with all the server processing, a folder full of css files (for presntation) and a folder full of script files (for javascript) if you use them.
Dont mix function with form (i.e dont put layout, colors and looks in the aspx/html page). This not only makes it easier to read and manage when you are developing but also easy to change things later.
As long as you organize everything correctly (personally i use divs) then you can place it where you like. And you can do some crazy things. Have a look at the home page on a site i built recently for a customer http://www.inspirationsbuyer.com which is all done using divs and css (with the odd javascript thrown in). Hardly anything is in a horizontal direction and took very little time to create.
CSS is VERY powerful when you know all the things you have to your advantage.
Also have a look at AJAX as this is a powerful tool and is free (the microsoft version is) and make sure you get the AJAX extensions and control toolkit ctp's. We are now building websites with the same rich ui as windows forms because of the power ajax gives us.
Both …

Re: Calculation in FormView part 2

if the texbox was bound to the database and there is no value then num1 num2 etc. is empty or null, neither of which will parse to a double to be able to be added. You need to do a test to see if they are null or empty and make thier value 0.
The easiest way is to set the value to 0 when you pull it from the database (either set the value to 0 or put 0 in its place in the stored proc). Or you can do it just before you do your sum.

Re: Loading All Database Name

Just run a select query in the master database where the object is a database. anything in SQL Server has to be registered in the master database. When you create a table, stored proc, user etc. it is stored in the master database. Of course you need the correct permission to access the master database, but it is all there.

Re: Error Opening Project

Ok. Because you reinstalled XP it is most likely the ASP.NET account or similar got messed up too.
The easiest (but time consuming) was to fix it will be to do a repair on Visual Studio (start the setup and choose the repair option - i think it is reinstall the same components or something).
That should reregister the ASP.NET account (Which i think is the problem) run IIS, register the isapi dll and a few other things to get everything back in sync.

You could try them all one at a time, but (i dont mean to sound negative) you are not familiar with the inner workings of windows and networks, accounts, IIS, com dlls etc and would be too risky to talk you through it. A reinstall will fix it.

Re: Deploying ASP.NET application

Did you enable IIS through the server management tool?
If you open IIS and expand the server, check that under web server extensions ASP.NET 1.1 is allowed.
Then on the properties for the virtual directory, make sure that on the Home Page tab the execute permissions are for Scripts only and the application pool is set to defaultapppool (you can change them later but lets get it going first)
My memory isnt too good with .net 1.1 but i think there is also a tab there saying asp.net (though it may have come along with .net 2) make sure you have your app set to use .net 1.1 on there
If these dont work then you should get some errors from the web browser and also should see some errors in the application event log and possibly the system event log too.

Let me know how you get on

Re: Datagrid

when do you call CalcColumn()?
You havent quite grasped the concept which is where you are going wrong but thats why we are here :)
Are you using a strong typed dataset to get your data? You dont want to add the unbound column to the grid in a grid editor (this isnt an unbound grid column its an unbound datacolumn - there is a big difference in the two).

Wherever you get your dataset from... before you pass it to the grid to bind it, thats where you need to put those lines of code.

It will work, its just you arent calling it at the correct time (if at all).

So you need to
1. Get your dataset from the database
2. Add the unbound column with the expression to the datatable
3. Bind it to the grid.

If you have a strong typed dataset then you can add the column there and even set the expression there. IF not then you have to use those few lines of code.

Try and grasp this concept (unfortunately they are similar names so everyone gets confused in the beginning). You have a database which has tables and columns. You have an ado.net dataset which has tables and columns (these can map one to one but do not have to! thats very important.. it was done deliberately to give us more power... old ado before ado.net would …

lol dont worry.. will teach us both to pay more attention.
Like i said before... take a break and come back to it.. sometimes you cant see the wood for the trees or just keep following the wrong path over and over.

It should work now. The GetValueNames() should return a string array with all the names in the key (not the data you highlighted in pink but the corresponding Name column) then we went through each of those in turn and called the GetValue passing in the name one at a time... this will then return your highlighted data one at a time.

Re: Help with another key. (Almost done)!

Thats because you made a mistake. In C# a \ is an escape sequence (used for special characters such as carriage return \r or new line \n). So a \ in a string is also a special character and so needs the escape sequence ie \\. As you see in your other reg strings (you left it out in this one).
The other way round it if you are not using special characters in your string is to use the @ symbol in front of the quotes which tells c# to take the string literally (beware if you use this then \r will appear as \r not a carriage return.

So your choices are hklp = hklp.OpenSubKey(@"HKEY_CURRENT_USER\Software\America Online\AOL Instant Messenger (TM)\CurrentVersion\Users"); or hklp = hklp.OpenSubKey("HKEY_CURRENT_USER\\Software\\America Online\\AOL Instant Messenger (TM)\\CurrentVersion\\Users"); both will work :)

Re: C# Classes

maybe consider using a property for each of these. It would appear that you will want something outside of your class to change the values so you dont want to make your fields public (or internal) as you have no control over the values in there.
To create a property you need a private field and a property for each as follows:

private string _name;
public string name
{
  get 
     {
       return _name;
      }
  set
    {
      //do some validation if you want
      _name = value;
      //do some other stuff if you need to based on the new value
    }
}

You have full control when someone changes the value now.
I use them alot as private properties for just in time instantiation (the field is populated the first time the property is used so it isnt taking up memory.
Also you can make it read only by not using the set part of the property (leave it out altogether)
You can also have different accessors so the get part can be public and the set part can be private or internal.

Hope it helps you

Re: C# VS2005 - Installing deployed application to an specif path

What are you using to deploy the project? If you create a setup and deployment project you control the install directory there (though if you dont want the end user to be able to change then you have to do some changes to the setup UI too - though i always recommend you let a user choose).
If you want to fix the path for some reason - it rings warning bells. Why are you hardcoding paths? They should be relative to the application. If you need to hardcode to get to something then you should use isolated storage instead (for example if you are storing settings or some information that the user configures).
If it is to get to something in your app then you should use a relative path from your app directory (if you need to pass the full path to something you can get the app directory path at runtime).

Re: How to convert CD's to audio files&make downloadable from site?

One other point worth mentioning (I just saw your hosting info) is that playing music over the net (whether embedded or not - its the same) is heavy on bandwidth useage which you will be limited to a monthly amount. An average song in both MP3 and WMA is just over 3Mb. An average CD is about 50Mb. So for EVERY USER (not song but visitor to your site) that plays music is chewing up your bandwidth heavily - 50Mb instead of an average 50kb for a web page with a pic or two.

Re: How to convert CD's to audio files&make downloadable from site?

Ah no, that is a totally different set of requirements. You asked to have files being able to be played and downloadable. The tutorial and embedding streaming is for online radio station type scenario. In this way you control the files played (its your playlist so they play in order you selected - so for the end user this is like listening to a radio station, and all they do is press play (or you can have it play on load). In the first scenario then it is more like a juke box where you give them a list and they can play one or more but need the player on their pc.
It all depends what you are trying to achieve?

1. Rip a CD (if using win media player there is a rip button) either in MP3 or WMA
2. Upload the file to your website
3. Put a link to the file on your website

When the person clicks the link it should automatically play on their pc providing they have a player (which just about everyone does). If they want to download it then they just right click and save as.
