hi,
I am doing an application which displays images dynamically.i have resized the images to fit to the screen.
Now when i display the images, the images seems to be pixelized.
There are more dots around the border of the image.
How can i reduce this pixelization?
Any ideas.
Thanks in advance

public void ResizeAndSave(int MaxWidth, int MaxHeight, string UrlAndFileName, string UrlAndnewFileName)<br />
{<br />
Bitmap OriginalBmp = (System.Drawing.Bitmap)Image.FromFile(UrlAndFileName).Clone();<br />
Size ResizedDimensions = GetDimentions(MaxWidth, MaxHeight, ref OriginalBmp);<br />
Bitmap NewBmp = new Bitmap(OriginalBmp, ResizedDimensions);<br />
NewBmp.Save(UrlAndnewFileName, System.Drawing.Imaging.ImageFormat.Jpeg);<br />
}<br />
<br />
<br />
private static Size GetDimentions(int MaxWidth, int MaxHeight, ref Bitmap Bmp)<br />
{<br />
int Width;<br />
int Height;<br />
float Multiplier;<br />
<br />
Height = Bmp.Height;<br />
Width = Bmp.Width;<br />
<br />
if (Height <= MaxHeight && Width <= MaxWidth)<br />
return new Size(Width, Height);<br />
<br />
Multiplier = (float)((float)MaxWidth / (float)Width);<br />
if ((Height * Multiplier) <= MaxHeight)<br />
{<br />
Height = (int)(Height * Multiplier);<br />
return new Size(MaxWidth, Height);<br />
}<br />
<br />
Multiplier = (float)MaxHeight / (float)Height;<br />
Width = (int)(Width * Multiplier);<br />
return new Size(Width, MaxHeight);<br />
}<br />
You must to invoice the resizeAndSave Function. the parameters are four
Here you have a parameters examples
MaxWidth : Final width size (pix) = 200
MaxHeight : Final height size (pix) = 200
UrlAndFileName : The original image Url = c:\folder1\image1.jpg
UrlAndnewFileName : The final path and file name, to save the NEW resized image = c:\newimage.jpg
PD: Only works with jpg images
Check tue quality picture and tell me if it you are looking for.

Hi Dear,
Fiest of all please calrify if you are using master page or any user control.
I this is the case please try to find the exact id of the control from view source.
You have not mentioned in which event you are handling this code. Please provide some clarification regarding this.
|
|
|
|
|
default.master
+ default.aspx
+ asp:listbox1
+ asp:listbox2
I use master page. The control is inside default.aspx and the id is listbox1 and listbox2. I use asp.net 2.0 c#. I both try to make enableviewstate true and false.

Hi my dears,
I`ve written a Web UserControl which has a timer with interval and elapsed event. and I want to raise an event in Timer elapsed method. then I defined a delegate and an event in my Web UserControl . Now I should register this event to my default.aspx page and catch the raised event from my web userControl in a method in my default.aspx page.
But I dont know how to register event in aspx page! the code I used is :
<br />
public delegate void myDelegate(string s);<br />
public static myDelegate myEvevnt;<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
System.Timers.Timer myTimer = new System.Timers.Timer();<br />
myTimer.Elapsed += new System.Timers.ElapsedEventHandler(myTimer_Elapsed);<br />
myTimer.Interval = 3000;<br />
myTimer.Enabled = true;<br />
}<br />
protected static void myTimer_Elapsed(object source, ElapsedEventArgs e)<br />
{<br />
myEvevnt("hhh");<br />
}<br />
public partial class _Default : System.Web.UI.Page <br />
{<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
_Default.Event += new reminder.myDelegate (RecieveEvent);
}<br />

Use DateTime calss and follow code.
DateTime dt= DateTime.Now;
dt=dt.AddMonths(3);

Hi,
This ca be achieved by AddMonths method...see below
<br />
Dim dt As DateTime = DateTime.Now<br />
Response.Write(dt.AddMonths(3))<br />

Hi
I'm using ChangePassword control(asp2.0) in which I've a literal control with viewstate disabled but literal control retains its text during postback. Even tried to use following code to clear text but with no result.
Protected Sub ChngPassword_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles ChngPassword.Load
Dim ltr As Literal
ltr = CType(Me.ChngPassword.FindControl("FailureText"), Literal)
If Not ltr Is Nothing Then
ltr.Text = ""
End If
End Sub
Any idea what eles could be done.
Thanks

Hi Friends,
I have two modules in my website. One is user end and other is the admin section. I want to implement form based authentication for both.
In the web.config, I set the authentication to "Forms" and mentioned the loginURL i.e. login.aspx which is at root. But when I traverse the admin section pages, it still redirects me to the login of the user end.
I want it to redirect to the login page of the administrator
(adminLogin.aspx)
Can i add a new web.config in admin part??????
If you know the answer ... please reply.
Thanks,
Sushant Duggal.

Yes you can have a separate web.config file for your admin part provided your admin section is in a separate folder.

You can put credentials to each user i.e. user or admin store along with login id and password so that from single login page you can make athentication as well as autherisation

Hi sushant,
Add new folder to your project, copy all forms related to admin module to that folder, Add another web.config for that folder and make changes according to your requirement. New web.config will override the functionality of rootfolder web.config.
