Standard question #1:
What do you mean by "not working"?
Standard question #2:
What error message do you get?
What does the sbDataToPost method do?
What does SendingParameter contain?
Do you url-encode the data that you send?
Ahmad Adnan wrote: srWriter.Write(sbData);
There is no overload of the StreamWriter.Write method that takes a StringBuilder. Don't you get a compiler error on that line?
Ahmad Adnan wrote: catch
{
return false;
}
Don't catch everything and throw it away like that. Only catch the exceptions that you know how to handle, otherwise you'll never know what went wrong.

Hi All,
I am trying to drag and drop a div in javascript. I am calling this function on button click event.
function CreateControl(id) {
var ctrlString="";
ctrlString+="";
ctrlString+=" ";
ctrlString+="";
ctrlString+="";
ctrlString+="
return ctrlString;
}
This function creates a div which contains two other divs and one textbox and a button. Actually it is a chat box window which has a header, message area and textbox in which user types in message and click on send button to post to it other user.
I am using following code to drag and drop this control:
document.onmousemove = mouseMove;
document.onmouseup = mouseUp;
var dragObject = null;
var mouseOffset = null;
function mouseCoords(ev){
if(ev.pageX || ev.pageY){
return {x:ev.pageX, y:ev.pageY};
}
return {
x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
y:ev.clientY + document.body.scrollTop - document.body.clientTop
};
}
function mouseUp(){
dragObject = null;
}
function ClearAllObjects() {
dragObject=null;
}
function getMouseOffset(target, ev){
ev = ev || window.event;
var docPos = getPosition(target);
var mousePos = mouseCoords(ev);
return {x:mousePos.x - docPos.x, y:mousePos.y - docPos.y};
}
function getPosition(e){
var left = 0;
var top = 0;
while (e.offsetParent){
left += e.offsetLeft;
top += e.offsetTop;
e = e.offsetParent;
}
left += e.offsetLeft;
top += e.offsetTop;
return {x:left, y:top};
}
function mouseMove(ev){
ev = ev || window.event;
var mousePos = mouseCoords(ev);
if(dragObject){
document.getElementById("Text2").value=dragObject.id;
dragObject.style.position = 'absolute';
dragObject.style.top = mousePos.y - mouseOffset.y;
dragObject.style.left = mousePos.x - mouseOffset.x;
return false;
}
}
function mouseUp(){
dragObject = null;
document.getElementById("Text2").value="0";
}
function makeDraggable(item){
var obj=document.getElementById(item).parentElement;
document.getElementById("Text1").value=item;
if(document.getElementById("Text2").value="1") {
if(!obj) return;
obj.onmousedown = function(ev){
dragObject = this;
mouseOffset = getMouseOffset(this, ev);
return false;
}
}
else {
dragObject=null;
}
}
function Button1_onclick() {
var txtId=document.getElementById("Text1").value;
if(txtId!=null){
document.getElementById("Text1").value=document.getElementById ("Text1").value + 1;
var divHtml=CreateControl(document.getElementById("Text1").value);
}
else {
document.getElementById("Text1").value=1;
}
document.getElementById("mainSpace").innerHTML=document.getElementById("mainSpace").innerHTML + divHtml;
}
Now the problem is that i want that window should be dragged by clicking on header only. It works fine when page is loaded first time. But once i drag it from header then after that it gets dragged on mousedown event on any area of the window. I have tried to figure out the problem but to no vain. I will appreciate if somebody knows the solution of this problem.
Thanks,
Ahmad

Hi all,
I'm using GridView with an ImageField column and somehow it doesn't display the pictures in my db.
This is the code for adding new picture to the db (which I took from codeproject site)
<br />
if (!Page.IsValid)<br />
return;<br />
if (!FileUpload1.HasFile)<br />
return;<br />
try<br />
{<br />
int len = FileUpload1.PostedFile.ContentLength;<br />
byte[] pic = new byte[len];<br />
FileUpload1.PostedFile.InputStream.Read(pic, 0, len);<br />
int glrId = int.Parse(_GallaryDropDownList.SelectedValue);<br />
_engine.AddPicture(gallrId, pic, _DescTextBox.Text);<br />
}<br />
catch<br />
{...<br />
}<br />
The GridView markup is the following:
<br />
<asp:GridView ID="GridView1" runat="server" ForeColor="Navy" Width="100%" AutoGenerateColumns="False"<br />
DataKeyNames="picID" DataSourceID="_PicturesSqlDataSource" Font-Names="Arial"<br />
Font-Size="11pt"><br />
<Columns><br />
<asp:BoundField DataField="picID" HeaderText="picID" InsertVisible="False" ReadOnly="True"<br />
SortExpression="picID" Visible="False" /><br />
<asp:BoundField DataField="picGlrID" HeaderText="picGlrID" SortExpression="picGlrID"<br />
Visible="False" /><br />
<asp:ImageField DataAlternateTextField="picDEscription" DataImageUrlField="picData"<br />
HeaderText="picture"><br />
</asp:ImageField><br />
<asp:BoundField DataField="picDEscription" HeaderText="description" SortExpression="picDEscription" /><br />
<asp:TemplateField><br />
<ItemTemplate><br />
<asp:CheckBox ID="_SelForDelCheckBox" runat="server" /><br />
</ItemTemplate><br />
</asp:TemplateField><br />
</Columns><br />
</asp:GridView><br />
When I go to that page, I can see the rows but I cannot see the images, I can see the alt text instead..
Can you help me with that? What am I doing wrong?
Thank you,
Roy.

Im writing a page that contains a data repeater.
within the repeaters item template i go into javascript and declare an SWFObject (this is a javascript helper class for writing out flash videos onto the page). I need to pass the SWFObject some data from the item that is binding to the repeater (see the bold code bit below). If i try this...
<asp:Label id="lblVideoTitle" runat="server" text='<%# Container.DataItem("VideoTitle") %>'></asp:Label><br />
<script type="text/javascript" charset="utf-8"><br />
var so = new SWFObject("vidHolder.swf", "myVideo", "604", "360", "8");<br />
so.addVariable("thumbURL",'video_clicker.jpg');<br />
so.addVariable("videoURL",'<%# Container.DataItem("VideoURL") %>');
it simply does not work as it wont break into the ASP like it does with the HTML.
Does anyone know/understand a way around this?
Regards,
Guy

Just make an external method in javascript that takes the url as input and processes it like:
function DeclareSWF(url)
var so = new SWFObject("vidHolder.swf", "myVideo", "604", "360", "8");
so.addVariable("thumbURL",'video_clicker.jpg');
so.addVariable("videoURL",url);
And in the server code just call it :
DeclareSWF('<%# Container.DataItem("VideoURL") %>')

but that doesnt solve my problem because you still have to call the javascript and pass a server side variable.
Ive already setup the function in the head of the aspx page but in my repeater i have to break into a script block to call 'DeclareSWF'.
How do you suggest i do that?
Because in the 6 years ive been doing asp.net if never figured it out!

Guy

Hello worldwide developers.
here is my problem:
The business rule is that not just anybody should be allowed to register on the site, so only the users with a role "Property Manager" should be allowed to register new users....
So when she registers a new user, the new user will either be assigned the role "Property Manager" or "landlord"
The issue comes in now because we use the built in register control from the toolbox...which currently does not give an option for selecting roles. So at the moment a new user is not even given a role.
So my question is, how can i manipulate the register control?...or hard code it?...so that the Property Manager can select a role when registering new users.
Hope someone can help.
Thanks people

I don't think is possible. When executing from server, server have accsess only from Root of your specificied server.
But here is a fact.
when using \ in strings, it is intended to be special char
example:
\n - NewLine
\t - tab
\\ - Display \
you have to change.
C:\\images\\abc.jpg

You need to use virtual path only you can not user physical path in ASP.Net applications I mean you can but it will then find the file to clients hard drive.

Try to write a short subject line for your post. Putting the entire question in the subject line makes it too long to be useful.
You can't use C# functions in SQL.
The Trim function is used to remove spaces at the beginning and end of a string. What you need is a function like Substring. Look in the documentation for the SQL syntax of the database you are using.

you can use the following query...
string str = "Select cr_name, substring(cr_pic,4,len(cr_pic)-4) from criminal"
“The woods are lovely, dark and deep. But I have promises to keep, and miles to go before I sleep.”
