I have problem with uploading image to sql database.. In asp.net form i use this input

<br />
<Input ID="MyFile" Type="File" RunAt="Server" onclick="return MyFile_onclick()" /><br />

On database i have atribute in table defined as image. What do i have to insert now to this table,this atribute(named pics) that i could load image from database and displayed it in page? Do i have to make separate table, where i need to insert image title, image size, image type? I tryed with inserting MyFile.Value into table atribute(type image) but it didn't work!!

In form i have also imagebox. How to display selected image from MyFile in this imagebox?

Thanks

It saves and retrieves the images from DB.

Ok i have looked at article..i understand how it works, but when i used it with asp.net application i didn't get full path of file to use it in stream. I tryed both asp:fileupload and input type="file" with PostedFile.FileName and nothing retrieves full path. Everytime i get error that selected picture wasn't found in C:\\windows\\system32\\filename.

I tryed to saved it there, but then i get error for reading rights..

Any idea how to deal with this.?

Hi..

I m working on a web application where I have simple structure.
I have root directory and a secure directory.
root directory have pages which all users can request, and secure directory will be accessible to users who are authenticated. ( I dont need roles as i will have only one type of users)..

can you tell me how to proceed for authentication..

thanks,

There are several different ways to accomplish this; what have you tried so far?

If your users have to log in you should be able to create some logic which tests for that and redirects or allows through as appropriate. How are you managing the users?

Hi.. thanks,

I am storing users in database. only username and pwd.
Once user is logged in certain links will appear ( links for secured pages).

so I want , only valid users can request these pages..

I simply want to stop someone directly using Urls in address bar for these secured pages..

thanks,

One way would be to create an attribute that would test to see if the current user is logged in/valid. If not, then redirect to another page. You would create the attribute and then decorate the page class; see the tutorial or fond one more suitable.

Attributes Tutorial[^]

This is just one way and it may not be the best for you (or anyone, for that matter). Do some more research and see what else you can come up with on your own, try it and then come back when you get really stuck.

Hi.

I am storing username to a session["userid"] variable, once the user logged in.

How about checking the session value on the page_load of all secured pages.

and if dont find the value redirect to "custom_page"

thanks

You need to read following guide for creating xml file
from your data.

Fusion Charts[^]

Give this xml file/string to the fusion chart function to generate
and render the charts. The guide will help you to do so.

I am not able to understand why and how
you need to access client side database.

But for getting client IP

Use this..

Request.ServerVariables("REMOTE_ADDR")

css file not getting applied by asp.net page

Member 39190499-Jun-10 17:07

9-Jun-10 17:07

I'm getting a weird error. I have a css class and I dragged the reference onto the aspx.

The compile-time page is recognizing the reference to the styles in the css because when I remove the css reference from the aspx the page displays squiggly lines under the CssClass references with a tooltip "cannot be found".

However, when I run the page the css classes aren't getting applied.

Also weird - when I copy the css class definitions from the css file into a tag in the <head> variable of my page the css classes DO get applied.

I can't figure out why my css classes aren't getting applied at runtime even though the references appear to check out at compile time. Any ideas?

Have you checked the url of css file in the generated page source. It seems to me that the path of the css file is incorrect.

Try using ResolveClientUrl to set the css url.

<%=ResolveClientUrl("~/css/default.css")%>
