View 13 RepliesI have the following code, but the only issue with it is that I must load and refresh the webpage in order for it to work.
I'm using a HTA Application to display images, I wish to be able to use JavaScript to send the image URL to the rotating script, then the image/s will be rotated, and then I can reload the images without the need to reload the page or load another one.
Of course I need to use AJAX to send the image URL's to the script. I really don't have a clue how to go about doing this. Here is my test page which has a button and the image:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Debug="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I have a web app that allows users to upload images. Last week, all was well. This week, it appears the code is breaking. Here is the code:
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
If FileUploadControl.HasFile Then
Dim month As String = ddlMonth5.SelectedValue
Dim year As String = ddlYear7.SelectedValue
' Dim whatis As String = FileUploadControl.PostedFile.ContentType
Try
If (FileUploadControl.PostedFile.ContentType = "image/jpeg") Or (FileUploadControl.PostedFile.ContentType = "image/pjpeg") Or (FileUploadControl.PostedFile.ContentType = "image/gif") Or (FileUploadControl.PostedFile.ContentType = "image/x-png")
Then
Dim fs = New FileStream(FileUploadControl.PostedFile.FileName, FileMode.Open, FileAccess.Read)
'save file with new size
Using image As System.Drawing.Image = System.Drawing.Image.FromStream(fs)
Using bitmap As New Bitmap(image)
bitmap.Save("C:WebsitesimagesCusRespData.jpg", image.RawFormat)
bitmap.Save("C:Websitesimages" & month & year & "CusRespData.jpg", image.RawFormat)
End Using
End Using
StatusLabel.Text = "Upload status: File uploaded!"
fs.Close()
fs = Nothing
Else
StatusLabel.Text = "Upload status: Only .jpg,.jpeg,.gif and .png files are accepted!"
End If
Catch ex As Exception
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " & ex.Message
End Try
StatusLabel.Visible = True
End If
End Sub
On the development side, I see this error: The file could not be uploaded. The following error occurred: Could not find a part of the path. On the production side, this occurs: The following error occured: A generic error occurred in GDI+.
Look at : [URL]... In this you can see a rotating images(along with text). And on click of this image...a server side code will get execute.
how can I implement the same in asp.net 2.0
Im not very experienced with JavaScript or Ajax so i want to know how simple is it to do my idea and is there any tools that will help me.
I have a folder with images, banners, which i have a c# code block that goes through and makes a list of all the files and their URLS.
I want these images to rotate automaticaly every 5 sec as the websites main banner.
No buttons, no mouse over, nothing more is necesary. The only thing is that it has to be dynamic, when the user has uploaded more images into the folder, these new files must be used as well.
So im asking all the great experts here. What is the easiest way to go?
I cannot explain the functionality actually. I want to rotate the links in spheric form. Visit this [URL]. On this site, see the region "Chemical formulas" in middle-left of the page, where links are rotating in spheric, circular form. I want this functionality using jQuery / jQuery in ASP.net application.
View 2 RepliesThe task is to rotate the text of a label in the web form by a certain degree. The label is present in a cell of a table. I tried functions like these (after googling) but error says PaintEventArgs/System.Windows.Forms.PaintEventArgs is not defined. Public Class Form1
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles Me.Paint
e.Graphics.DrawString("Hello World", _
Brushes.Black, _
10, _
10, _
New StringFormat(StringFormatFlags.DirectionVertical))
End Sub End Class
Private Sub Form1_Paint( _
ByVal sender As Object, _
ByVal e As System.Windows.Forms.PaintEventArgs _
) Handles MyBase.Paint
e.Graphics.RotateTransform(20)
e.Graphics.DrawString("Hello World!", Me.Font, Brushes.Blue, 0, 0)
End Sub
I have tried importing the below classes... but to no avail..
Imports System.Data
Imports System.Drawing
Imports System.Drawing.Text
Imports System.Drawing.Graphic
What am I missing? (Possibly I am not getting the equivalent class of PaintEventArgs in webform...) (Am using Visual Studio 2008)
I have a web page that performs searching, on very large database about millions and millions of records. The request for this has been sent from an update panel. We know that for this request, the server needs around 1hr to do such a search. And our client even accepts that the server might take such a long time. Till the request is of less than 30 minutes, our search result grid is updated on browser. But if the request is of more than 30mins the update progress keeps on rotating. There is no server timeout of either session, database, iis or the asynchronous post back, that we have defined in script manager.
I have verified my whole web.config and also the machine.config file for any default setting of 30 but haven't got any. Update progress bar keeps rotating for request more than 30 minutes.
I uploaded some images and js files under aspnet_client folder of a domain account and it's giving me 403 - Forbidden: Access is denied.
The account is on Windows 2008 64bit machine with latest plesk installed,
I've confirmed read & execute permission is provisioned to Plesk IIS WP User, Plesk Domain User and Plesk IIS User still no luck.
i have a table with a hunders of image urls (paths) like( c:vijjishivam.jpg,. ),these images are present inside my local hard disk and im programatically setting urls to the image controls but im unable to view images.image URL property only working for images attached in the web application but not out side.
View 5 RepliesI implemented the Location tag in the web.config file to authorize the anonymous users for Images folder. I deployed the code in IIS6.0 with Forms authentication mode enabled for the virtual directory. I disabled all other authentication modes. When I browse the login page, Images are not displaying. When I set Anonymous authentication in IIS6.0 for the Image folder, it works fine.
See below the code implemented in web.config:

I'm using ASP.NET 4 Web forms routing, for example like this:
routes.MapPageRoute("page-browse", "{Language}/{Label}", "~/Default.aspx")
So the webadress could look like: http://localhost/mywebsite/eng/home
In the root of my website I have a folder "Images".
Image display works when I'm in the root of my website, e.g. by using http://localhost/mywebsite/default.aspx
But when using routing it doesn't work, because the image relative url will look at http://localhost/mywebsite/eng/images instead of http://localhost/mywebsite/images
Is there a way to prevent this using ASP.NET 4 Routing mechanism? Or is the only way to use absolute url's to images?
I've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.
I want to show on one of my pages a slideshow type page. Basically I want it to show a selection of images from a folder and have the images scroll from right to left.
View 8 RepliesI want to write one program by visual studio 2008 (C# and ASP) that has web application and windows application.
I want to get clients images in web app(upload) and store them in DB (mysql) then send these images to windows app via web service (so i new web service, not web site). But i have 2 problems:
I have 2 ways to store images in mysql, first i should have BLOB field in DB -that it takes more space-, second i should save just name of each image in DB(so have image in one folder) -in this way i don't know how get image from clients and store them in that folder-. which one? Or what other? How (code) can i transfer image via web service(Byte[] or? ).
I wanted to combine app_themes css files into one on the fly. I did so using Mads Cristensen technique. But now all elements that has background image defined through css (see picture) don't display image. I believe that is because css files are not relatively referenced anymore (../), but through axd file. I'm trying to fix this by changing reference to image files without success. I already tried background: url("~/App_Themes/44/images/myimage.gif") and this works for pages that combined css. But the problem is that there are other pages in this project that don't use this css combining and now they lost reference to background images.
