Javascript :: Saving Div Content As Image On Server?
Jan 18, 2012
I have been learning a bit of jQuery and .Net in VB. I have created a product customize tool of sorts that basically layers up div and add's text, images etc on top of a tshirt.I'm stuck on an important stage!I need to be able to convert the content of the div that wraps all these divs of text and images to one flat image taking into account any CSS that has been applied to it also.I have heard of things that I could use to screen capture the content of a browser on the server which could be possible for low res thumbs etc, but it sounds a little troublesome! and it would really be nice to create an image of high res.I have also heard to converting the html to html5 canvas then writing that out... but looks too complicated for me to fathom and browser support is an issue.I'm thinking perhaps I could do with two solutions for this. Ideally I would end up with a normal res jpg/png etc for displaying on the website, But also a print ready high res file would be very desirable as well.

I have a table in SQL Server with a field defined as Varbinary (MAX). In VB I am trying to save an image to the table. The file I'm using is 139kB in size and I get no errors but when I look at the record, the Attachment column where my image stream should be is empty. The rest of the information is saved. I checked the buffer and it grabs the correct size of the file (141475) so I'm very sure it's found and loaded the image.
Could the parameter from the SQL not be passing the binary value to the parameter properly?

I have read previous posts and used suggestions about firebug and selenium etc. I am still a newbie and am still pretty confused as how to implement this. I am trying to access URLs that appear when I click on a link. I have accessed the JavaScript code and the function just has a couple of parameters which I have no idea how to intercept using vb.net or C# etc.

What I am attempting to do is make a form for a tire shop. I want to put comboboxes on the left side of the form that the employees make choices from. I then want to put some kind of a table or grid looking thing on the right side of the form that will display their choices so that everyone in the shop can look at it see that "John is on bay 5 until 3:00pm". At the end of the day I want all of the combobox choices to save to a file..I dont really need the table or the grid thing to save..just the choices. If I want to do this, do I need to use that gridview tool? or can I make my own table thing to display the choices in.

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

I would like to receive user input from a JavaScript prompt box, save the value entered and then insert the value into a database. I am using VB.Net and MS SQL Server 2008. How can I do this? I tried using an inputbox, but it didn't popup like a prompt box, but rather, I had to click on it for it to show up, which is not user-friendly. Is there a way I can achieve what I want to?

How can i load the original image when the tumbnail version of the image has been clicked? Im using ASP.NET in combinaton with javascript.
The original images are big, so they have been scaled on server side. This makes the site load faster. But somehow, both versions (original and tumbnail) of the images are being downloaded.
I'm trying to download only the tumbnail version of the image. And when the user clicks on the image, i want to show the original image.

Say I have a simple web app written in asp.net/vb.net. The web page has one button. When you click it, it does some junk in the code behind. What I would like to do, is when the page reloads, after the server has done its thing, to execute a JavaScript function.
Now the only stipulation is that it can only happen if the button was clicked. Not just on any page load. Is there a simple way to do this?
