I am using asyncfileupload ajax control and can successfully upload and save picture on server.I need to do the following and not sure how:When user is in process of uploading, I only want them to see *.jpg *.gif and *.bmp files
Once the user uploads their picture, how do I reduce the quality of the picture so it is less than 10 KB?
I am uploading images in c# windows application. I am uploading the images folder wise. In one folder there are 200 to 3000 images. My one images size is about 3.10 MB to 6.2 MB. Its dimensions are 3008 x 1960, 1960 , 4000 x 2600. 6000 x 4000 . while uploading i am reducing the size of image to 400 x 266 or 266 x 400 depending on the height and width of image. but still my image size is about 227 KB. Now i want to reduce the image resolution to decrease the image size.
My code is given below:
private void btnUpload_Click(object sender, EventArgs e)
{
getDestinationPath();
string ik = DestinationPath;
string ik2 = DestinationPath2;
string lastFolderName = Path.GetFileName(ik);
[Code] .....
I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then
Dim stream As Stream = FileUpload1.PostedFile.InputStream
Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower
If x = ".jpg" Or x = ".jpeg" Then
Dim image As New Bitmap(stream)

i'm new to c# and i wanted to know how can i allow user to upload a picture from a text box and a button??
after uploading the picture, how can i save the picture in the database??
**note**the picture i allow user to upload need to be in a fixed size.
I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook
but still dont work
I ve an application dat am working on. The section of the upload picture works perfectly on the development environment and also on a test server but the issue comes up when it was hosted life. I started geting an error dat says picture could not be attached. I ve a folder cald Passport and dis ve been working for me on befor now but i dont now the reason y its not working now.
protected void btnUpload_Click1(object sender, EventArgs e)
{
Boolean fileOK = false;
String fileExtension = string.Empty;
String path = Server.MapPath("~/Passport/");
if (fuPassport.HasFile)
{
fileExtension = System.IO.Path.GetExtension(fuPassport.FileName).ToLower();
String[] allowedExtensions = { ".gif", ".png", ".jpeg", ".jpg" };
if (allowedExtensions.Contains(fileExtension))

fileOK = true;
}

In the Java world for instance, there are some very sophisticated tools to manage the quality of the source code, and that cover more than one dimension, such as :
Coding Rules
Comments
Complexity
Unit testing
Code coverage
etc.
These tools are very useful to manage the technical debt. They connect to a repository of source code and scan it. They can be triggered automatically just by the fact of committing the source code.We have a large number of ASP.NET applications to maintain and evolve, and have continuous flow of demands for new ones to be created. We know that we have a technical debt, but we are facing some challenges of identifying it and having it under control.
there are some tools to manage the source code quality in ASP.NET applications like those mentioned above.
I have a script which resizes images, I did not write this script, nor do I know any ASP.NET, but I have been assigned the task of fixing an issue with it!
The problem is, the resulting image from the resize appears to be of less quality than the upload, even if the file uploaded is already set to the correct size.
Uploaded image - [URL]
Resized image - [URL]
The script that is doing the resizing is as follows, how to correct the issue?

In our project We made reports with the method that return as a datatable from a class with dynamic sql.
Nowadays, we think to migrate to more professional technic for our reports. For this purpose I examine crystal report and devexpress' XtraReport components.
However, I Couldn't decide which component and method(dynamic sql, stored procedure etc.) should I use.
how to get the best software to use for the following?
(i) Web graphics: Apart from Photoshop what is the best easy to use program (minimum learning curve)for producing quality drawings suitable for a website?I know that there are many graphic programs around but I want one that is easy to use and produces QUALITY drawings.
(ii) Animations: Similarly I am looking for an easy to use animation program. I have used Flash before but I feel that there is a steep learning curve. Is there a better program out there?
I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it.
First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly.The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference.My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.
The code to render the image is the following:

The method ResizeImage() do the resizing of the width and height respecting the aspect ratio and keeping in a max width and a max height limits.

View 1 RepliesI'd like to setup some lunch-and-learn sessions in my company where we all watch a presentation of some programming-related topics. Where are some good places to find videos about Microsoft technologies with a clear picture and high audio quality that are about 30-60 minutes long?
They could be about design patterns, best practices, new language features, new frameworks, getting better performance, etc.
How can I check the quality and bit-rate of audio & video files in C# asp.net?

View 3 RepliesI have been asked to join a very small team where one main developer has been buiding the web app (.NET 4.0) during ~6 months. The project should be delivered within next 2 months.
After first look at the code I can say that I would never allow it to go to production (things like catch { }, no tests at all with WebForms etc).
So the code quality is incredibly low.
My task is to improve that and still deliver the solution. So I plan to start with unit testing and MVC2 reimplementing most of the functionality (though using some of the existing code).
I estimate that I will need about 6 weeks to catch up with the current progress and be on te same functionality level as the application will be in 6 weeks.
The problem is that the main developer who has been working on the project seems to be really starting in IT and many basic things are unknown to him. It will take significant amount of time and effort to educate him how to do the proper testing, development and apply some patterns.
I am ready to take responsibility for the reimplemnting the application but at the same time I don't want the main developer to be on idle but as he won't be able to significantly contribute to the better-world project at this stage I am not sure what would the best way to keep productivity high for both of us.
Currently I think following solution is good enough: He proceeds doing what he does until I will catch up with him and then start working on a new project together.
The problem is that of course this approach is not very productive as one developer will do better-world project while the other will proceed with what he did, effectively doing similar tasks.
Another approach would be to pair and try to do things together, but again not sure how productive we will be.
Can you suggest how we could better organise the work together in order to be most efficient for the overall project?
