I think this is what your looking for.
Your example makes no sense to me, and I don't see the point of it. If your sql server is loaded on your hard drive, why not use the standard connection string?
As far as using a programmable path like %ProgramFiles%, that's a Windows thing, which works in certain scripting languages and the cmd prompt. I don't think the application that reads the web.config file is smart enough to translate %ProgramFiles% to the proper file path, and if it did, you need to see if it adds the final slash to the end of the path.
You still have to code the database name to make it work. Since it's on your hard drive, a trusted connection should work fine.
Server=.\SQLExpress;AttachDbFilename=c:\asd\qwe\mydbfile.mdf;Database=dbname;
Trusted_Connection=Yes;
[Edit]
If you need connection strings, go here

Richard, I was talking to the OP, still getting use to the new look and feel.

Hi all,
If you know any site providing advanced graphic controls for web development, please suggest.
Controls like AJAX controls, different colored check box, radio option etc..
Thanks a lot in advance!

why we have a number of data controls in asp.net (like, repeater, datalist, gridview, form view etc )? What is differnece between form view, list view, and datalist Controls.

Because each of them has different use and need. All are important and used for data presentation in form or other.

 Why did you not try to look for it on Google/Bing[^]?
One of the link: http://itmall.blogspot.in/2008/10/what-is-difference-between-gridview.html[^] - In a nutshell, it says:
GridView:
(1)Can select one row to do something.
(3)update, delete records in database, but not insert
(4)Sort, paging
(5)Concurrency handling
(6)Display empty data
(7)Formatting (e.g. alternative row style)
(8)Customize field (e.g. use TemplateField to edit record)
(9)Extend (e.g. create LongTextField for GridView)
ListView:
(1) template driven
(2) can add data to database
(3) can edit, page through, sort database data
(4) ListView is the only control implementing IPageableItemContainer interface, so it is the only one which can use DataPager control.
ListView is the most flexible List control in all. I can safely use ListView in place of GridView.
Repeater:
(1) display database records. It cannot edit/insert records
(2) entirely template driven
DataList:
(1) display database records(can edit?)
(2) entirely template driven
DataList is very similar to Repeater except that DataList's default behavior is rending the content using a table. However, you can override the default behavior.
DetailsView:
(1) Display/edit/delete/Insert records in database
(2) Render a table for a single record. always render each field in a seperate table row.
FormView:
Exactly like DetailsView except that FormView is entirely template driven.
ListControl:
there are RadioButtonList, DropDownList, CheckBoxList, BulletedList, ListBox.

I am struggling converting image to byte array using client side script.
I have to convert image to byte array, and pass this array to web service or Page methods, so that the web services or Page methods can save the image in sql server. Any one please help me
Thanks in advance,
Please help me....
|

[edit]
At first I didn't think that was possible. I know javascript can do many things, but to read an image file sounds far fetched.
Apparently, there are many articles about reading a image file as a base64 array of chars. Transmitting it to a web service would be easy, but since it's not a primitive data type like a string or integer, you would have to consume the array in a class first, and then as a primitive type. That's get a bit tricky especially in vb, but there are many c# examples out there that work fine.
I use uploadify with a sub process attached to it. I suppose I'm one step away from being able to complete your task, I just need to do the javascript end, and update my class. and modify a web service for it.
As far as starting from scratch, write the javascript first, and then work on the web service side, and just write the file to the disk drive for testing to make sure the byte array is intact.

hi jkirkerx,
Thank you so mush for your reply,
I have tested below code
var p;var canvas = document.createElement("canvas");
var img1=document.createElement("img");
function getBase64Image(){
p=document.getElementById("fileUpload").value;
img1.setAttribute('src', p);
canvas.width = img1.width;
canvas.height = img1.height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img1, 0, 0);
var dataURL = canvas.toDataURL("image/png");alert("from getbase64 function"+dataURL );
return dataURL;
}
My problem is , above logic IE cant support
Any idea plz advise me ...

I ran into that about 2 months ago, IE has it's own set of rules for createElement, while Firefox and others use the standard rules, or in other words, the ones on the mozilla website.
As an example
innerText versus innerHTML
Plus, it's case sensitive, and by the way, sometimes you won't get an error, it will just read the value and do nothing in either browser.
I would have to spend an half hour and run the code to see what's happening, to modify it.
I would run it in IE, and press F12, or use the developer module, and set it to script, and run the page, it will catch the error on the right pane, you click on it, and shows you the source in the left pane, with the cursor on the error and a explanation.
I'll get back to this in about an hour

I'm not running html5, but while debugging your sample, I ran across this datasheet
http://msdn.microsoft.com/en-us/library/ie/ff975241%28v=vs.85%29.aspx[^]
This is probably a better sample for IE. OK, onLoad you Draw() the image in the canvas, then click the button to get the data that was drawn image.
<!DOCTYPE html><html>
<head>
<script type="text/javascript">
function draw()
{
var canvas = document.getElementById("MyCanvas");
if (canvas.getContext)
{
var ctx = canvas.getContext("2d");
ctx.fillStyle="white";
ctx.beginPath();
ctx.rect (5,5,300,250);
ctx.fill();
ctx.stroke();
ctx.arc(150,150,100,0,Math.PI, false);
ctx.stroke();
}
}
function putImage()
{
var canvas1 = document.getElementById("MyCanvas");
if (canvas1.getContext) {
var ctx = canvas1.getContext("2d");
var myImage = canvas1.toDataURL("image/png");
}
var imageElement = document.getElementById("MyPix");
imageElement.src = myImage;
}
</script>
</head>
<body onload="draw()" bgcolor="lightgray" >
<div>
<button onclick="putImage()">Copy graphic using toDataURL</button>
</div>
<div>
<canvas id="MyCanvas" width="400" height="400" > </canvas>
<img id="MyPix">
</div>
</body>
</html>

hi jkirkerx
Thank u so mush for your reply, I have used uploadify.js process, Now it working with session inproc mode but , here we have used session stateserver mode so we cannot save httpposted file in session.
What i will do now..plz help me.
|
|
|
|
|
I didn't use the html5 version of uploadify, so I'm not sure how it works.
I had to write a Sub Process module, that mimics a webpage on upload, and I saved the image file on the drive in a temp location, actually a library, in which the image can be retrieved again for reprocessing. The Sub Process Module was session capable, so you can set a value. So my Sub Process uses system.drawing to create 4 images in various sizes, and writes a temp image with a temp name for previewing. Then I wrote a cleanup function that searches for previous temp files by date and time, and deletes the ones that are 1 day old.
Why are you trying to save the byte stream in a session?. You can save it as a byte() array or memory stream, just save the filepath in the session, or are you making it cluster ready?

Looks like you have placed this Javascript in a separate JS file. Place it in it's related HTML/ASPX page and it should be available. Currently, the get cannot formulate the variable to access and look for the object.

Hi,
I want to ask how can I set a regular expression with the following:
Usernames can only contain alphanumeric characters (A-Z, 0-9) or a period (".").
Periods (".") cannot be at the beginning or end of the user name.
Username can have one Periods (".") only.
Usernames must be at least 5 characters long

Haven't seen you around for awhile, was wondering if everything was ok.
