All those 5 buttons share same event handler? If yes, you can use parameter sender in that event handler. If you have a separate method, you need to add a parameter to it and pass the sender to there.

To expand on Navaneeth's answer/
void MyClick(object sender, eventargs ea)
{
Button button = sender as Button;
if ( button != null) // should always be the case
{
// here you can use if (button == button1, or you can use switch(button.Name), or check the Tag property, or whatever.
}
}
The way I tend to do this is to use an enum to identify the different actions, and then stuff that into the tag property, pull that out and switch on it. This means that it's typesafe instead of switching on strings.

how can i split particular part from the image based on the pixel coordinates?
|
|
|
|
|
By using a DrawImage overload to draw just that section of the image onto a new image that's the right size to receive it.

In the server path there is an image folder.

When you say 'windows applicaiton dll', it doesn'th ave windows UI, right ? It's just a dll ? Won't it be in the bin directory ? So, you need to either pass it the folder, or know what it will be, relative to where the dll is.

The dll have a UI. From that UI user communicate. After opening the UI the browser will close and communication only thru the DLL UI. I need to access the folder from server.. ie same Server.MapPath in asp.net, but i need it from DLL UI. Socket is used to connect diffrent clients.

i create a windows application and convert to class library and use the dll in the web application.
|
|

Still i cant see the Posiility of what you are saying, mybe its better you explain step by step, because you might be saying the wrong terms. tell me if am wrong , i suspect that you have created a Windows Application(Project) and in the Solution you added another Project of a class type and compiled it and produced a DLL, and now you wanted to use that DLL in another Web Application. Now if am right about this , how did you go about using the DLL in the web Application ?
My be it would be better if you explain step by step what you did

OK, so this dll is downloaded by your web app and runs on the client side ? Then why would it need to know the path to images on the server side ?
Server.MapPath plainly won't do anytying when the code runs on the client.

Yes, i need to access a image from the server and display in the client application , and need to sent to another client in the network
|
|
|
|
|
So, this app is only going to run on a network, not over the internet ?

Use DataTable.Select.
C isn't that hard: void (*(*f[])())() defines f as an array of unspecified size, of pointers to functions that return pointers to functions that return void

Hi all,
Actually I was trying to read a word document line by line in a simple way using Filestream and streamreader and storing in a string and creating a new document with the same. But i am unable to that document in a proper way. while debugging i have noticed that the contents in the word document are coming in a format like "ÐÏࡱá\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0>\0\0þÿ\t\0\0\0\0\0\0".
when I try to open the new document i prompts me to "select the encoding format that makes the documnent readable".. The partial code is below for refernece...
FileStream fs = new FileStream(txtDoc.Text, FileMode.Open, FileAccess.Read);
StreamReader srText1 = null;
srText1 = new StreamReader(fs,System.Text.Encoding.Default);
string s;
s== srText1.ReadLine()
here txtDoc.Text contains the path of the word document...

I don't know what to say. Word documents are in Word format. .NET doesn't know how to read those, it's going to try to turn them into strings, as you're seeing. You need Word on the target machine and to control it from .NEt to open word files.

Your thread is not aborting properly. This makes the application to run until all threads finishes. You need to re-work on your thread abort code and make sure it aborts correctly when application ends.
Run the new thread as background. This will abort the thread when main thread ends. You set IsBackground property of thread to make it as background.
Thread t = new Thread(..);
t.IsBackground = true; You can also use a ThreadPool instead of creating your own thread. ThreadPool threads are background thread by default.

Hello All,
Can i use Binary Searlization to pass a dataset over web service or i need to use only xml searlization for this? Please advice...Thanks!!
|
|

You don't need to worry about serialization in web services. Serialization will happen internally when web services are used. It uses SoapFormatter to do the serialization.

Webservices uses only XML Serialization.Whih id done internally as Navneeth says.
AFIK,We don't have any option to change the formatter.
