I'm in one class and would like to use a string that was defined in another class. Ho to...
|
|
|
|

Is the string a static member or instance member? A static member can be referenced without object references like
MessageBox.Show(ClassWithString.MyString);
If it's an instance member, you have to create an instance and then refer to it like
ClassWithString cws = new ClassWithString();
MessageBox.Show(cws.MyString);
Of course, I'm assuming that ClassWithString is accessible from your code and that the string is public. HTH. 
Cheers,
Vikram.

Hi all,
I have devloped a Remote Managment App. where server captures the
updated regions of its screen and sends to client.
Problem is that server captures the area which is updated and then
sends. Updation is so frequent and so quick if i will try to send
all the updates as they occur then i think evrything will stop.
So i stores the updates info into a queue and then get them one by one
and sends to client. It looks all will be fine but after some data
tranfer my client stops receiving data. Why i dont know?
What protocol i have to use to make my session a reiable one and
to minimize memory usage by removing intermediate queue?
Thanx

The protocol probably isnt the problem. You may be overloading the receive buffer of the client so that it stops accepting data, or any number of other problems. You may want to send black and white only with your remote management, especially if you are currently using 24 or 32 bit colors. With black and white 1 byte can represent 8 pixels and will go MUCH faster than having to transmit 4 bytes for each pixel. There is a HUGE number of things that could be happening, but I doubt the protocol you are using is a large part of it.

A couple things, since your monitor application is busy screen scraping choosing a protocol that is reliable is probably the best choice. In other words, TCP over UDP. The reason is with UDP, datagrams can be dropped, duplicated, or sent out of sequence. The latter does not bode well for a monitor client. Sure you could build in a retry and sequence mechanism but why? TCP will do that for you.
So now you have to further decide to proceed with managing the I/O. For one, having a real-time expectation may be a tad unrealistic. You will probably have to back off your update interval to a few seconds. At the minimum make it a tunable paremeter so that you can see performance on the fly.
The other huge consideration is what is your I/O model? If you app is already multi-threaded then you will probably want to use one new thread to scrape and enqueue or scrape and send. If you choose to buffer between the screen scrape and the actual send, make sure you use a AutoResetEvent or Mutex to signal the Send Thread it is time to send (i.e. updates are in queue).
If you architecture is asynchronous then you absolutley need to make sure your TCP I/O is also asynchronous. In other words use a non-blocking socket and use Begin/End for connect/accept, send/recv operations.

hi!
i inherit a windows form then added a property named ListControl that is a control type.
if i'll set the value for this property, the list of possible values were already filtered by control type.
what i want is to filter it again by datagrid and listbox. so it's just like having a second level filter. how can i do this?
any ideas or suggestions will be appreciated!
thanks in advance!;)

Hi!
I am looking into how possibly I could enable users re-arrange items in a listbox or listview by dragging an item from one index into the desired index.

Hello,
I am writing two programs, one in c++ and the other in c# and am using windows messaging for communication between them. As of now, the c++ program successfully sends a message to the c# program and the c# program receives it just fine. I need the c# program to send a reply message to the c++ program after it finishes its tasks. I have ran into some problems. First off, here is the code in c# that I am using to define the SendMessage function...
DllImport("user32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public static extern IntPtr SendMessage(IntPtr hwnd, uint Msg, int wParam, int lParam);
I did some research on this dll import and found multiple variations, here is one...
[DllImport("user32.dll")]
public static extern int SendMessage(int hWnd, uint Msg, int wParam, int lParam);
does anyone know the correct variables to used so a c++ program will accept the message.
further more...
I tried both declarations of SendMessage and the c# program still did not send a reply message. Note, I used spyxx.exe to find this out. I saw that the message from the c++ program was received but no reply was sent out by the c# program.
here is how I am sending the reply message in c# program...
Form1.SendMessage( Form1.FindWindow("ConsoleWindowClass", "camController"),
REPLY_PICTURE_READY,
0,
0);
I would greatly appreciate input on this, thanks

Jesse Liberty's Programming C#, on O'Reilly press. $40 new, probably can get used for $30ish. The approach is really one of "ok, so you know the basics of programming in general, here's how you program in C#." Its not C# for dummies, its C# for programmers.

Hi,
I have an XML file which has number of nodes(written using WriteXML() from a dataset)....
It looks like....(small sample)
- <newdataset>
- <schematable>
<columnname>F1
<columnordinal>0
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>General
<columnordinal>1
<columnsize>255
<datatype>System.String
- <schematable>
<columnname>Number
<columnordinal>2
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>Currency
<columnordinal>3
<columnsize>8
<datatype>System.DateTime
........(it continues till end of file).
Here ,i need the node DataType datas(sys.string,sys.double...) alone to fetched and stored in an array for further purpose ...
How to do it?Help me
Thanx...

I think you can read the contents of the nodes only as strings. Once you've read the content of a node, you could try Int32.Parse(), Double.Parse() and so on, and see if what you've read is an int or a double or a string.
HTH. 
Cheers,
Vikram.

Vikram,
Actually its a XMl file with formats as in all normal XML files....
I want to read those contents of the Element <datatype>(here ,mistakenly printed as System.String,System.Double etc...They belong to <datatype>)...
I need to read the value(system.string,system.double...) alone from this tag...
This is for checking a condition...
Cud u tell me yaar?
Thanx

Assuming you'll be using DOM style parsing, load the document using XmlDocument[^] and iterate through the nodes, using the Value[^] property to get the actual value.
Something like
XmlDocument doc = new XmlDocument();
doc.LoadXML(strXML);
foreach(XmlNode node in doc.DocumentElement.ChildNodes)
Console.WriteLine(node.Value);
Regards
Senthil

I had created an MDI application for Touchscreen based dvpt using C# .net.
I have placed 3 panels in the MDI parent. The Top panel, left panel and center panels. The top panel displays the application name. the left panel displays the navigation buttons. The center panel displays the necessary details. Here i need to pop-up some windows to display some details. the pop-up windows are child forms. When i set the parent and pop-up these windows, they hide at the back of the panel and are not visible. If i do not set the mdiparent then they are visible. How can i overcome this problem?
Regards,
Madhu Srinivasan

The centre panel is blocking the child MDI windows. You can either get rid of the centre panel and place your user controls elsewhere, say the toolbar, or set aside an area within the centre panel, maybe another panel, and set this as the parent of the child windows (the child windows would then be normal windows, not MDI children, and set the WindowState to Maximized.
I am leaaving for work now, but if you are still having problems, e-mail me a *small* sample project and I will take a look at it when I get there.
