}
// Read file into a data stream

Assalam-0-Alaikum,
hru? well in .Net 2.0 there is a file upload control. put it on ur .aspx page. In code behind file
provide its id and press a dot(.). Now the real fun starts here.
--- to get file name :
dim fileName As String = FileUpload1.PostedFile.FileName
then u can use this string fileName to save it in the database using inLine Query or Stored Procedure etc. If u have Problem Inserting data in the database, do let me know. i would write u know how to do this.
-- to Save file in the specified Location:
FileUpload1.PostedFile.SaveAs("Location as string")
there are other properties and method for the fileupload control tht u could use but depend on the requirement.
Hope it Helps.
Regards.

hai i am using the file upload control indotnet as told by you.but here i want store the path of the image where it woulb stored not where it was stored.
accaording 2 ur soln it stores the the path of the image from where it upload the image...so can u solve it.
|

|

Assalam-0-alaikum,
yes i would tell u. look its u who will decide where to store the file. like,
fileupload1.postedfile.saveas("c:\myweb\images\image1.jpg")
now save the same path in the database i.e., c:\myweb\images\image1.jpg
now Question arises how to differentiate files. give them a unique name.
now how to give a unique name? there are so many ways but how do i save is, i create a folder with the username, save the file and name it with the username concatenated with some other patameters to make it unique.
hope u get it.

Hi phuhoa
In ASPX, variable not stored in a long time. Just whene the page is created. To use long life variable use session (however in default just 20 minuites).
Like the example:
First, store your variable
Session("textbox1") = textbox1.text
To retrieve it
textbox2.text = Session("textbox1")
Hope it is usefull for you.

If both are different web application then pass the value in query string if you don't know how to pass the query string please google it
Thanks and Regards

Hi Sandeep, Hi phuhoa
Query string is also a nice choice to "transfer" the variable. However, it is not really safe, when we deal with the security.
Let us follow the sample:
Me.TextBox1.Text = Request.QueryString.Get("prevpage").ToString
*Change the prevpage with the value of previous page.

Yes its not Secured but i think in his application that is not main concern
as it is the value that user is going to enter i don't think it will cause any trouble or security concerned . If you change the the quesry string then result will different just simple

Yes,There is no inbuilt Trim Function in javascript.
You should implement own function for the trim white space like this
function Trim(s)
{
// Remove leading spaces and carriage returns
while ((s.substring(0,1) == ' ') || (s.substring(0,1) == '\n') || (s.substring(0,1) == '\r'))
{ s = s.substring(1,s.length); }
// Remove trailing spaces and carriage returns
while ((s.substring(s.length-1,s.length) == ' ') || (s.substring(s.length-1,s.length) == '\n') || (s.substring(s.length-1,s.length) == '\r'))
{ s = s.substring(0,s.length-1); }
return s;
}

Just use this code and enjoy urself.
// Removes leading whitespaces
function LTrim( value )
{
var re = /\s*((\S+\s*)*)/;
return value.replace(re, "$1");
}
// Removes ending whitespaces
function RTrim( value )
{
var re = /((\s*\S+)*)\s*/;
return value.replace(re, "$1");
}
// Removes leading and ending whitespaces
function trim( value )
{
return LTrim(RTrim(value));
}
// Call this Function
function Test()
{
var _test=trim(' Devjit Das ');
alert("'"+_test+"'");
}
Devjit Das.

Hi All
Could you give me a solution for multiple postback problem. In this case, if you click a button, it seems that it is executed 2 times. Honestly, I dont know "a thing" that cause it. I just use 1 masterpage, 1 control and one page.
Appreciating for your comment much.
Regards
Azmi

Yes it was happening with me also in my case the reason was
In aspx if you see Page directive there is AutoEventWireup property which is true by default and we also had written Page_init and Page Load event decalration in it. that was in 2003 in declrations sections . IN fact in 2005 there is no need to wtite it in code behind file as it is present in designer page
Thanks and Regards

Hi Sandeep
Thanks for your reply.
So, what should I do? Is it delete the AutoEventWireup property or just set it into false? Btw, in my code AutoEventWireup property is set into false (in html markup sections). But, it is still create twice postback. I test it with Response.write("<script>alert('test')</script>"). In result, alert test is comes up twice, which means there are 2 postback.

Azmi
