Hi Guys and Gals. I urgently need information on how to use the Vertical Scroll bar in Windows forms. If any of you would be able to point me to a project that might contain the code I need it will be greatly appreciated.
Kind Regards,
Elizma

Sorry, I have no project to point you to, but the documentation can be found here[^]. Adjust the properties Minimum and Maximum to determine the interval of the scroll bar. Respond to the ValueChanged event and read the Value property to reflect changes when the user scrolls (or optionally use data binding).

Dear Elizma,
U can do one thing.
Please take the contents in one DIV Tag and via that u can apply the VertivalScroll Bar.
Thanks and Regards,

It means you're trying to compare two strings that are in different formats. COLLATE[^] is, from memory, the thing you need to play with. Although I don't see how you can compate Latin and Arabic fonts.

Hi all,
I did a chat application. But I stuck in the finishing point.
I used a windows service as server. This windows service will create and maintain a remoteable object. The clients are connected to this remoteable object using tcp channel. In addition, I implemented an application for the interface of server. This windows application will run on the server machine. Users are added throw this windows application. In addition, the available users and their status will display in this application.
The windows service with startup type automatic will always run on the machine. Whenever the windows application for the server interface started, It will call a function on the remotable object to attach this application to windows service.
remotableObject.AttachServer(this);
'this' will stored in the 'remotableObject'. So whenever the clients become online or offline, they will send a notification to windows service. If the server interface application is running the windows service will try to list the status of users in a list box. To do this, windows service will pass a serialized class of 'users' to server interface application. Everything is ok till here. I could deserialize the 'users' object. Now only one job is remaining is that list the users in a 'listbox' control. But when i call the functions of listbox, the program stop responding. No errors are displayed. Can you guess what is the problem?
Thanks and Regards,
Mic

Hi Mic,
As per my concern, You are going to update the UI (Form item). I would to say, If you want to update the UI then please do it with the help of delegates. I thought yor are update the UI in any event so it going to stuck.
Please go through how to update the UI via deligates.

Oh yes  the scenario I explained above, it happened when the server interface tried to add a user to remoteable object. Its work in an event of server interface windows application. I tried another example, which is not call from any event. It is working. Therefore, as per you said I will use delegates. But how can you understand that it is the problem of events? Actually I didn't understand what is the real problem that's why I ask. Thanks for your precious advice.
Thanks and Regards,
Mic

Hi there,
if i got an 3 arraylist to be serialize, each with different type(Point[] or int) how do i deserialize them back to the 3 different arraylist accordingly. Should i save the number of items in each of the arraylist? Check the type? What other methods would u suggest?
Thanks in advance.

If you serialize the lists into separate streams, just remember which list resides in which stream and you'll be fine. If you serialize the lists into one common stream, though, make sure you deserialize them in the exact same order they were serialized.

i need to save all the arraylists into a common arraylist and then serialize it because i want to save it into a file. Is this correct?
Below is part of the code i wrote:
In Save()
<br />
ArrayList arr = new ArrayList();<br />
<br />
arr.Add(Arraylist1);
for(int i=0;i<br />
{<br />
GraphicsPathData gpd = new GraphicsPathData((GraphicsPath)PathList[i]);<br />
Stream gpdStream = GraphicsPathData.Serialize(gpd);<br />
arr.Add(gpdStream);<br />
}<br />
<br />
arr.Add(Arraylist1);
<br />
formatter.Serialize(myStream, arr);<br />
myStream.Close();<br />
<br />
in OpenFile()
<br />
ArrayList arr =new ArrayList();<br />
if (openFileDialog.ShowDialog() == DialogResult.OK)<br />
{<br />
filename = openFileDialog.FileName;<br />
Stream myStream = openFileDialog.OpenFile();<br />
if (myStream != null)<br />
{<br />
IFormatter formatter = new BinaryFormatter();<br />
arr = (ArrayList) formatter.Deserialize(myStream);<br />
myStream.Close();<br />
<br />
.................
However the problem here, how can i separate the arr into the correct arraylist?
Thanks for your help

You don't need a common arraylist to serialize several arraylists into one file. Just make several calls to formatter.Serialize passing the same stream:
formatter.Serialize(myStream, arr1)
formatter.Serialize(myStream, arr2)
formatter.Serialize(myStream, arr3)
To restore the arraylists, make the calls to formatter.Deserialize in the exact same order:
arr1 = (ArrayList) formatter.Deserialize(myStream);
arr2 = (ArrayList) formatter.Deserialize(myStream);
arr3 = (ArrayList) formatter.Deserialize(myStream);

hi there,
Thanks for the reply. Your solution works perfectly for binary serialization. However, i was wondering, does this concept works the same if i want to use XML serialization?
Thanks.

Change your Flat Style as "System" it will take your Operating System style/skins (Ex. XP).

Dear Siva,
Is that is happening in debugh mode or it happens in release build also?
I also face the same problem while debugging the application  but it works fine in release build.

Control.CheckForIllegalCrossThreadCalls = false;
Put this line in the constructor of your form.

Yes, when you are doing something referred to as "Illigal" then obvious choice is to disable the check so you can get on with your high quality code. 
Look at Invoke and BeginInvoke. Yes, they are annoying, but not half as annoying as the deadlocks you get when not using them.
