Hi all,
I have created a Page on which i want the user to be able to download files,
I want to display the name of the files and when the user clicks on the file name the save File dialog should be displayed so that the user can select the location of the file where it has to be saved.
Any sample code or links regarding this will be appreciated.
Thanks & Regards,
Pramod

The anchor tag will do this for you, depending. Where do the files live ? Are they on the server, or in the database ?

They are on a Sharepoint Server.
I get all the attachments from a list and display the names on the page by creating LinkButton for each of them.
now i want the display the save dialog box when the user clicks on the LinkButton and then the file should be saved on the location given by the user.
Thanks & Regards,

It's ALWAYS urgent
Most likely, you'd have the data in your database, and you'd link back to a page that shows the details that takes the Id of hte person on the query string, so you can load it from the database.
Are you doing this for school, or for your job ?

1 - give your variables real names
2 - handle the selected index changed event on the first list, and when it fires, populate the second list accordingly

Hello,
In windows application we are using datagrid in readonly mode. If user right clicks on particular cell then copy/ paste menu is displaying. User is copying content and trying to paste in other cell, as datagrid is in readonly mode so user can't paste, but in first cell it is showing edit icon.
We don't want that edit icon if datagrid is readonly, so I thought we can disable right click menu only.
If any other solution is available for hiding edit icon, please let me know.
Anybody if knows, solution for this, please give URL or sample code.
Thanks & Regards,
Kumar

Hello
You can disable the contextmenu if you path an empty menu to the property of the control:
ContextMenu cm = new ContextMenu();
yourControl.ContextMenu = cm;
Or you modify the existing menu liek you want.
All the best,
Martin

Hi,
I am doing an application that is using webservice & displaying data.So every 30 seconds the application will call webservice, I use system.Threading.Timer it is working fine.CPU usage is very less (maximum 30).I got an additional task to play video files.So it will be maximum 8 video in a screen (video files located in local system) & very 30 seconds according to data from ws video file will change.I write the code like this.In timer callback event I am Executing 2 functions
[Code]
System.Threading.ThreadPool.QueueUserWorkItem(new System.Threading.WaitCallback(GetNextPage), state); // going 2 next page, in a page displaying 8 rows
System.Threading.ThreadPool.QueueUserWorkItem(new System.Threading.WaitCallback(GetNextVideo), state); // displaying corresponding video
//in delegate of video I put the below code
wmp = (AxWMPLib.AxWindowsMediaPlayer)Arrctrl[0]; //Find the control bcos adding at runtime
thread = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(PlayCurrentWMP)); //PlayCurrentWMP is assign the URL & play
thread.Priority = System.Threading.ThreadPriority.Lowest;
thread.IsBackground = true;
thread.Start(wmp);
[/Code]
Please advice what is wrong in my coding. Thanks in advance

Cant tell from what you told us.
Some ideas/suggestions:
- maybe movie takes more than 30 seconds
- maybe you keep adding threads
- add a thread counter; increment it at the beginning of the threaded method (PlayCurWMP)
and decrement it at the end; show it all the time
- maybe you are exhausting the ThreadPool
- I would add logging in all relevant parts, so you get a history line of what is going
on;
- you even may try to correlate your CPU load (observed, or obtained programmatically) with
that time line.

hi,
Thanks for the reply.When I start the application I am adding control runtime.If I try to play the movie suddenly CPU usage become 100% & the application runs very slowly.
Can you suggest is it AxWMPLib.AxWindowsMediaPlayer taking the memory?
Every 30 seconds I am updating the screen using Threading.Timer & delegates.So id the screen changes I need to change all the videos.
Can you pls help me How I play video with out affecting my screen display & reduce the CPU usage?I am not good in threading.Please give the code...
Thanks a lot..

I dont have code for this.
I gave you suggestions and ideas, that will be it.
One more suggestion: make sure you dont have a thread touch a control it did not create
(on old .NET, before 2.0) that may cause almost any anomaly; on .NET >= 2.0 it should
give an InvalidOperationException with some cross-thread remark in the message.
Thats all I can do for you.

You can put the exe or Shortcut of the exe in windows startup
C:\Documents and Settings\Your Computer Name\Start Menu\Programs\Startup
Thanks

Do you mean when Windows starts or when a user logs in? In the former case, you'll need to create a Windows service; for the latter, see this[^] link.

Hi everybody,
I have a quick question about listboxes. I have a project where I want to take a string, and see if a Listbox full of substrings has any matches in it. So if the big string is "abcdefg" and the listbox has "arq", "bcd" and "qrs", then the answer is YES. For example:
//listbox is populated with "chunks" of data
string xyz;
foreach(string in the listbox)
{
//does this listbox string exist somewhere in the big string xyz?
if(true)
{
//do something
}
}
I have no idea how to do this. It seems simple enough but there doesn't seem to be the right method out there.
Thanks for your time,
Michael Fritzius

you iterate over the items collection of the listbox, and you use methods on the string class to see if one string contains another.

Michael,
Something like this...
foreach (string item in sourceString)
if (sourceString.Contains(item))
{
}

Hi,
I dont think your example makes much sense, unless you somehow specify the minimum
length required for the matching substring.
Without it, every string contains "" (that is the empty string)
and I expect most strings contain a vowel such as "e" or "a"
If that is nevertheless what you really want, then do what the other replies
indicate, but put it all in one more loop in which you generate all the valid
substrings of your "big string". You might want to fill a list with these
substrings once, any way you see fit.
