Web Forms :: Read And Insert Image Into A Database
Feb 10, 2010
i am newbie to asp.net.i am trying to make sign up kind of webform where user can submit his image. i have used fileupload control to take image from user.i want to insert that image into a database.how can i achieve this functionality?
I m uploading a text file. I want to read that text file line by line and I want to save that data into database if there are no errors in that text file. I have 5 different columns in database and I want to take those 5 columns data in the text file and insert into respective columns.
For this, which is the best way to do. Can we read and insert data into respective fields in no time.
I am unsure on how to perform this task, what i need to do is make a gallery with tagging. I need this as it is a requirement for the project. Each user will have there own gallery and be able to upload and delete images from there gallery. I already know how to insert and select images from a database. I will then display the gallery using a data repeator with paging, I am sure i can google an article for data repeator with paging.
My challenge is, when the user wants to save a image to there gallery, he must 1st upload the image and then i must some how display the image, when the image is displayed, i will have a text box where they can add tags, this textbox will save in the tag table for that user_id, picture_id and the tag will have an id also. I am unsure on how to do this When he clicks save, i wanna insert the image into the table, and the tag. If he does not click save, then nothing should be saved. Now the 2nd part.
In the data repeator, i want a modal window to popup when they click an image, this modal will have the image and the respective tags that where saved for this image, I am unsure how to this.
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
