If you are using Sessions to check if the user is logged in then it can be done on the server side by check the null for the session. or you can still do it on the client site.

Is it necessary to install asp.net on that computer on which a deploy project of asp.net is installed.and if it is a web application then how we get domain for it and a perticuler site name.
|
|
|
|
|
Yes You Need To Install all the features of asp.net in which u r using for the local system i.e. for example u r using chart control for the chart control u have dowload chart control in local system .The same control should be daowloade at the client system
They Are So many domain providers in which u need to pay amount depending upon the capacity for example godaddy is one of the provider

It seems to me that you are a very poor candidate for the person to deploy ( or write ) an ASP.NET site, if you're asking this. Perhaps you need a book ?

Oops you really need to buy a Book. This is Basic knowledge. anyone who write asp.net apps must know this

In Host System you need to install .netframe work(dotnetfx)of your developed project.If you use .net2.0 then install dotnetfx2.0.If net3.5 then dotnetfx3.5.Need not install asp.net on host System.Take domain from the domain serivce provider like whois,godaddy.
In Host create a virtual directory for your application.

Hi
I have a peculiar problem here and I can't by my life figure out what the solution is. Note that the following code is not dynamically created, but just immediately in my aspx file.
Submit
This works just fine as long as I don't have the onclick attribute there, i.e. the OnServerClick handler is fired as it should. But when I use the onclick attribute it is not, no matter whether I confirm or decline the confirmation dialog box.
Even if I do like following for is never submitted
Submit
What am I doing wrong? Thanks

Im not realy sure but i think you can only have one event per control.
|
|
|
|
|
No, you are wrong. You can have an OnClick and an OnClientClick.

The answers you are getting are wrong.
Server events are a mirage. They get replaced with client side events. You need to write an OnClientClick event if you want to have javascript run in your code. ASP.NET is going to replace anything else you write, with an onclick, which is the proper HTML that needs to be written for all the browsers on earth, so if you write it, you're fighting ASP,NET

i m using C#.net app with access database
i have a employee table with the following columns
Sr.NO(PK), Employee_ID, Category_ID, Image_ID, Description
i want to display the records on the basis of category selected from drop down and then following that Category ID i want to pick the relevant Employee_ID and want to display the name from another table on the basis of that ID
any idea how and where to display that record ??
|

|

First of all you need to bind one Dropdown list with the Category field. When user select the category you need to execute another query to pickup the name from DB and bind it wherever you want.

i have a code in C# for access database
make an upload folder in your project file
Label1.Text = Server.MapPath(@"~/Upload/" + FileUpload1.FileName.ToString());
FileUpload1.SaveAs(lbl_path.Text);
Image1.ImageUrl = "~/Upload/" + FileUpload1.FileName;
Label1.Text = FileUpload1.FileName;
and now through insert command save Label1.Text into your database
and for retrieving the picture
and for retrieving the picture
use select command
give id of that row in some textbox
cmd=new oledbcommand("Select Image from Images where ID='"+textbox1.text+"'",con);
rd=cmd.executereader();
if(rd.read())
{
textbox2.text=rd["Image"].tostring();
Image1.ImageUrl=@"~\upload\"+textbox2.text;
}
hope it works

Hello All,
I have really a simple question, what is the best way (in your opinion) to provide an AJAX wizard like interface?
Now I have implemented this functionality in several different ways in the past but I just want to get the input of some other people on different methods of getting this done and their advantages / disadvantages.
Really what I'm looking for is something built using AJAX that will allow me to have several steps that are processed asynchronously.
All thoughts and ideas are welcome.
If at first you don't succeed ... post it on The Code Project and Pray.

Hi, I have been using Virtual path in Web site model successfully and recently i am thinking about upgrading my websites to web applications and here I got a confusion. I know, Web applications are pre compiled and must be compiled in a DLL and then deployed in the production server. If I have virtual file which is ASPX page with inline code, will that work in Web Application as the inline codes wont be compiled to the dll in the compile time, right ?

my problem is that i am trying to convert multiline textbox text to gif format. every thing works fine except the text which is to be converted convert only first line .
i think it is converting text box text as a single line
any suggestion plz
here is my code
Bitmap b = new Bitmap(330,TextBox1.Text.Length, PixelFormat.Format32bppArgb);
Graphics g = Graphics.FromImage(b);
string message;
g.Clear(Color.Yellow);
message = TextBox1.Text;
StringFormat format = new StringFormat();
int alignment = 1;
if (alignment == 1)
{
format.Alignment = StringAlignment.Near;
}
format.LineAlignment = StringAlignment.Center;
g.DrawString(TextBox1.Text, new Font("Kruti Dev 010", 12, FontStyle.Regular), new SolidBrush(Color.Black),new PointF(2.5F,.5F) ,format);
Response.ContentType = "image/gif";
b.Save(Server.MapPath("IMG\\"+img+".gif"), ImageFormat.Gif);
b.Dispose();
Response.Write("file uploaded Successfully");
}

This is more than a little insane. You need to use MeasureString to get a width and height.
monu_khan wrote: Graphics g = Graphics.FromImage(b);
Why not use a using statement, instead of leaking resources ?
monu_khan wrote: new Font("Kruti Dev 010", 12, FontStyle.Regular)
Another leak, plus if you change the font, it means you need to measure the string for that font.
Although you're using ASP.NET, this question has nothing to do with ASP.NET, it's about some basic graphics work. Why do you waste server space by saving a string a a bitmap instead of as text ?

Dear all,
I am having problem with placing the proper condition inside the postback method. I am trying to do the following:
1. There are 2 dropdown lists in my program.
2. I have two DropDownLists databound on the webform. The autopostback of the first dropdown list control is set to true. The contents of the first dropdown list is hardcoded. The contents of the second depend on the selected item in the first. In other words: The selectedvalue of the first DropDownList is passed as a parameter for the query at the basis of the second DropDownList's datasource. And this works: Whenever I click on an item in the first DropDownList, the dependant items are shown in the second DropDownList.
3. If I click submit then the specific rows from the DB will be pulled based on the values selected from dropdown list 1 and dropdown list 2.
Problem: In the postback method I think all the times the "ANY" MLNO is selected instead of selecting a specific value from the dropdown list 2. And that's why always all the values are pulled from the DB.
The code is as follows:
Code:

}
}
}
Thank you all who will try to solve the problem. To me it seems that the the second dropdown list is getting refreshed everytime I am posting the page back/submit and that's why "ANY" is getting selected and thus it's pulling all the data. This is not the whole code, this is only the part I thought might be useful to suggest any solution. Though other people might feel it's useless(!).
