View 2 Repliesi'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 am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.

Something is wrong with my registration page. After I register a user, it goes to the complete section of the page, but anytime I return to the register page, it only displays the complete section instead of allowing me to register another user. I tried logging out, but that doesn't change it. What have I done wrong?
View 1 RepliesI am currently developing a solution in which the user logs in once and can work on multiple customers at the same time on my site.I've looked at all possible solutions involving sessionid having stored the customerid, to launching a new browser session so i could have multiple sessions for one users etc. I also looked at using cookieless sessions.But the all fail because it's not a simple solution and in my opinion a simple solution is most of the time a good and predictable solution.
Therefore i came up with the idea to use url rewriting(i've seen this used in other applications). When the user opens a customer, i would like to start his url as follows "~/Customers/xxxxxxx/*.aspx" where xxxxxx represents the customerid. and *.aspx represents a complete subset of pages of my site. This would allow me to use a simple technique to use multiple user sessions within a single asp.net session.
Now coming to my problem, I have never done some url rewriting, therefore my questions:
- Is this possible.
- Can i protect all the pages that need a customerid as input(come to think of it, if no customerid in the querystring, redirect to a selection screen would be sufficient).
- How do i adopt all urls used in a sitemap etc in a structured way.
I have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.
When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.
I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?
Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...
I'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv. What is the best way to approach this? Can it be done client-side with Javascript?
View 2 Replies 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.

m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook

View 1 RepliesCan any one let me know about the below issue. I have a page which has three labels, say startdate,enddate and username. My issue is if the user doesnot select any of the above three then a message gets displayed as "Please select one search criteria" or if the user doesnot enter the date in correct format then i dispaly "Please enter date in mm/dd/yy" format. But what is happening is first time if the user doesnot select any then "Please select one search criteria" is getting displayed and after this message gets displayed if the user enters wrong format of date then both the messages are displayed.
View 5 RepliesCurrently i'm saving pictures to our sql server db. A user can go to a clients info page and click an id card image to open a new tab or window and see the picture saved for that client.
What I would like to do is when a client info page opens a small version (thumnail) of the picture to display and let the user click the thumbnail to open a bigger icture in a popup window.
Once I upload an image to the server (asp.net), I need to display this uploaded image for cropping. What is the best-practice to achieve the same(ie how do I send te image back to the client for display)? . I have tried giving a preview option before upload. But this does not seem to be working for all images. See here
Addition :
[I know JCrop is available , but the point of the question is how to send the image back ofr display]
I'm trying to remove all white or transparent pixels from an image, leaving the actual image (cropped). I've tried a few solutions, but none seem to work. Any suggestions or am I going to spend the night writing image cropping code?
