Hi,
I want to find out the exact location ,size and co-ordinate of line in the Page so can Multi-threading is also a way and if multithreading is the way then how it is possible?
i know that suppose there is a word document and i am writing any thing word is checking my spelling (called spell check),here there is two simultanious thread is working one is searching co-ordinate and another is checking the spelling so in my application also i use multithreading concept?
this is my theoritical assumption but does it work practically?
regards,

Multithreading might not be the best implementation technique simply for determining the row and column numbers of your cursor. While it is nice to think of a thread as running concurrently with your main thread, in reality, they are still sharing processing space. If you do want to create a multithreaded application, then there are a few methods of going about this, some good, some really bad. First, you can start your thread when the application starts, and loop through it, constantly checking the cursor location. I think you'll find this is the worst approach you can take, as your thread will be interfering with your main application (and really you don't want a user to know it's even running.) Another approach would be to run a thread each time an event occurs which would possibly change the cursor location (such as a key press, or a mouse click.) These event handlers can simply start a thread, which handles finding the cursor location, and displaying it in your status bar (or wherever you want it.) This is better than the first approach, but I think an even better implementation would be to start one thread to check the cursor location, have it wait until an event is triggered, check the cursor, then go back into its waiting state until the next event is triggered. This way you don't have the overhead of constantly creating new threads to do the same task. Since this is purely a reader thread, I don't think you'll need locking mechanisms, but do a little research on it. If you do need to lock out the main thread, then you really aren't gaining much improvement over just calling a regular function when your events are fired.
Good luck

Hi,
Yeah great.Here i really like urs second approach in which one thread is start to determine the co-ordinate location and another theard is getting the related co-ordinates or do some thing into event but here we can't use event becoz event is never been fired in whole process as user will not do any thing on the image,not even click the image and not even key pressing.
so i think here we can stuck in approach.
yeah but if you have done this kind of some thead applicaiton which will do same kind or related kind of applicaton then pls. send it some code so i can understand the things and naturally i am also doing research on the same thing as much as possible but if u have some sort of code then pls. provide me which increase my confidance level to implement the module.
thanks again.

threading has nothing to do with your solution, it's just an implimention detail that you may pursue. You're no closer to solving the problem, you're just expecting too much of threads ( as many people do ).

Hi,
I am facing problem in searching line in scanned image.Here i am describing the situation.
Suppose there is a page and in that page there is one ractangle at anywhere,but for that firstly we are finding Top line of the rectangle and here we are getting stuck becoz we are planning to start to searching from (0,0) left ,top of the page and go up to end of the whole page and by this way we want to find out the line and then after finding line we can find out rectangle,main problem is that now how we find out the line object?
regards,

damn, is that really all one sentence ?
If the colour is unique to the rectangle, then scan for it. Otherwise, you'll need to do something funkier.
Read my image processing articles for how to iterate through a bitmaps bits in C#.

Can anyone help me simplify the code below, given that MyObject and OtherObject comes from a 3rd party COM component (some DLL from somewhere)?
<br />
public class BaseClass<br />
{<br />
public void GetPropsforMyObject(ref myObjHere, CommonStuff commstuffhere)<br />
{<br />
myObjHere.CommonProperty1 = commstuffhere.Prop1<br />
myObjHere.CommonProperty2 = commstuffhere.Prop2<br />
.<br />
.<br />
.<br />
myObjHere.CommonPropertyN = commstuffhere.PropN<br />
}<br />
<br />
public void GetPropsforOtherObject(ref OtherObjHere, CommonStuff commstuffhere)<br />
{<br />
OtherObjHere.CommonProperty1 = commstuffhere.Prop1<br />
OtherObjHere.CommonProperty2 = commstuffhere.Prop2<br />
.<br />
.<br />
.<br />
OtherObjHere.CommonPropertyN = commstuffhere.PropN<br />
}<br />
}<br />
<br />
public class Class1 : BaseClass<br />
{<br />
public void Class1(CommonStuff commstuff)<br />
{<br />
MyObject myobj = new MyObject();<br />
<br />
GetPropsforMyObject(ref myobj, commstuff);<br />
<br />
}<br />
}<br />
<br />
public class Class2 : BaseClass<br />
{<br />
public void Class2(CommonStuff commstuff)<br />
{<br />
OtherObject otherobj = new OtherObject();<br />
<br />
GetPropsforOtherObject(ref otherobj, commstuff);<br />
<br />
}<br />
}<br />
Note that GetPropsforMyObject and GetPropsforOtherObject does almost exactly the same thing, except that the object being passed values to is different.
Neither can I modify MyObject and OtherObject because they are 3rd-party COM objects.
Any help would be appreciated

I'd add a constructor to the base class with the common construction code, and change Class1 and Class2 constructors to call the base constructor, like this:
public Class1(CommonStuff commstuff)
: base(commstuff)
{
//...this class does another thing afterward
}
or something like this.

This still doesn't work because I have to pass on different objects.
I'll rephrase the question somewhat...
How do I simplify:
<br />
MyMethod1(Object1 obj1)<br />
{<br />
...obj1 does something...<br />
}<br />
<br />
MyMethod2(Object2 obj2)<br />
{<br />
...obj2 does the same thing as obj1, it's just a different object...<br />
}<br />
to something like
<br />
MyMethod(Param param)<br />
{<br />
...method does its thing<br />
}<br />
Where param can accept both Object1 and Object2, even if Object1 and Object2 are both from external COM components.

How about assigning all the properties in a loop by indexing the props with something like FieldInfo[] myfinfo = myObjHere.GetType().GetFields() [or rather GetType().GetProperties()]?
I have about the same problem, cause i want to load all properties of my objects from a file (key=value) dynamically without millions of myobject.prop1 = file.prop1 lines.

hello,
I have programed a MultiThreaded TCP server using TcpListener, TcpClient and NetworkStream. What can be the best approach to check the active connections and close the inactive ones? I am looking for some way so that when client
closes the connection only then the connection closes, regardless if the comunication has taken place or not for a long time. Is there any way?

Actually I have an array of TcpClient and equal number of Threads for each client at the server. I have another thread (connectionDestructorThread) that is checking all these clients. If any client disconnects, this connectionDestructorThread should get the notification and aborts that client's Thread and free up resources.
I don't see how SendTimeout and ReceiveTimeout can help in this senario.

Zishan

Hi, I am planning in developing local applications using the architecture C# with MySql. Can anyone help me with the things I have to keep in mind?
I am using VS.net 2002, one question that I cannot determine because I have done this type of solution yet. If I use MySql as my database, is it required that I setup a Mysql server on the client pc that I am gonna implement my system?? How is it packaged then?
I have only tried using access and a client pc need not to have access when I install my system in it.
Can someone please help me on this? I am sorry for such a newbie question. Just want to cutdown through details thats why I am asking for external help and maybe get other cool suggestions. Thank you very much.
I just have to know

Not the easiest thing to deploy. Unless you really need to use MySql, consider using MSDE, which is a free version of MS SQL Server, and very easy to deploy.

I want to write a quoted string to a text file. The problem is that the string is in a variable and I can't work out how to get quotes around the text when written to a file.
Any suggestions appreciated.
Thanks
Stephen

If i understand you correctly, you are trying to include the " inside a string. Just escape the quote like:
string s = "this \"is\" an example";

That is what I want to do but the string is in a variable read in from a datareader and i am having trouble adding the quotes to a string which contains some text.
eg
string stext = "The text";
string stext1 = @"\"" + stext + @""\";
This does not work because the variable name is written as part of the text and not what is contained in the variable.
Any additional help is appreciated.
Thanks

That's because you have a mistake and stext is never even used!
This will work however:
string stext = "The text";<br />
string stext1 = "\"" + stext + "\"";
