but when i try to get the value using lblerr.text, it is showing null.
Try using this:
if (this.IsPostback)
{
string value = Request["lblerr"];
}
Hope it helps.

Probably by doing alot of graphics coding. Sorry I wasn't very specific, but your question is out of the scope of a post.

if you want to upolad picture then do it and same the image path on database.
and in user profile while retriving the information , give the image path on the Picture box.
|
|
|
|
|
which control should i need to store picture ???
thanks 4 ur last reply bt being a beigner i dont fully understand
|
|
|
|

you do not need any control to store in image.
when user select a picture to upload , then it will stored in a local drive
e.g:
ur application run on com1, com2, com3 and there is a server
now com1 user upolad his image , then the image will save in server
e,g: server\com1user\photo
now store that path in database with all other information . now while retraving , just retrive the path as string and give image1 url= stringpath
Now i think it is clear to you.
Good luck

Hi All,
(Visual C#, System.Drawing, GDI+)
I have developed a drawing area where i have drawn "Sample Text" in rectangle. The properties (Color and Font of text) are displayed in PropertyGrid.
Problem: if i change the color of text (in PropertyGrid), color of text is NOT changed immediately. It is changed only if i click on the text.
Any solution??

Hi,
How do I send a Textbox value to a SQL View?

Can anyone please help?

just pass the value with sqlcommand
cmd=create view + "'textbox1.text'" + as select.....

Not a good method, it is very near to SQL Injection Attacks[^].

I don't know why GE' designed it's API this way: you can get features like placemarks, but they don't have the Lon/Lat info at all! Yes, you can make GE "fly" there and then you can get the Lon/Lat via the camera, but the prerequisit is the feature's HasView==1. In practice I found most features don't have view.
How can I get the Lat/Lon of a feature?

Not sure, have you looked through all of their documentation?

If you read the values in javascript from the Session object...why don't you read on the server (code behind) from the Session object also?

This is a mainanance project.
am biginer to .net
so dont know much. i dont know how to do that. thats y am asking. i just want to know how we can get the value of javascript variable in c#
This is the function in javascript
function display()
{
var localpath1 = document.getElementById('lblerr');
lblerr.innerText = localpath;
}
|
|
|
|

from the javascript function i understand that you have an asp:Label control on your page. In this case in the code behind just use:
string Value = lblerr.Text;
My first reply referd at this code you wrote:
<br />
var customer1 ='<%=Session["customer"]%>';<br />
var journal = '<%=Session["journal"]%>';<br />
Using <%=Session["customer"]%> means that you insert a C# call to retrieve data from the Session object, which is also available in the code behind.
string customerValue = (string)Session["customer"];
Hope it helps.
