hi , i didnt asked my qustion in public bcz i know it takes too much time for getting the result .
i have make an execute program of the project that i has made with visualstadio 2010 .
i have setup it on my windows 7 , and it works fine.
but when im setup it in windows xp it'll give me an error
unable to load Dll 'libzmq' hresult 80070007h , and sth like this
but i have already attach the file libzmq , and why it didnt throw an error in windows 7 ?
should i attach any other dll to my project .
ty for any help .

It would help to know exactly what was contained in "and sth like this".
I suspect it was a BadImageFormatException beng thrown. The file libzmq.dll is a C++ library and therefore can't be loaded if you compile your project for 'AnyCPU'.
You need to compile for either x86 ot x64 when using C++ libraries, not for AnyCPU.
The version of libzmq.dll that I posted is the x86 version, so you need to compile your project for x86. It'll run on both x86 & x64, but you need to compile for x86.

i have already set it on X86
the exactly error that the program throw is :
System.DllNotFoundExpection:Unable to load Dll 'libzmq':The specified procedure could not be found.(Exception from HRESULT:0x8007007F)
at ZeroMQ.Interop.zmq_init(Int32_threads)
at ZeroMQ.ZmqSocket..Ctor(int32 type,Nullable 1 context)
at ZeroMQ.ZmqDealerSocket..ctor()
at WindowsFormsApplication2.form1.server()
windowsapplication2 is the namespace for my program and the server is the method that i call it with a threading.
so , any idea ?

Did you copy libzmq.dll to your bin folder?
Has the XP box got the right version of the .Net framework on it?
|
|
|
|
|
well i have checked the bin Box and i found the dll even when i wanted to build the program (make setup) i have put the file into the dependency so when the program want's to setup on other computer it'll copy all of that dlls (libzmq,zeromq) into the folder .and then i have checked the box in the windows xp , it was there .
and sth more , even your program haven't get executed there .
it throw an error on jim page is like :
System.DllNotFoundExpection:Unable to load Dll 'libzmq':The specified procedure could not be found.(Exception from HRESULT:0x8007007F)
at ZeroMQ.Interop.zmq_init(Int32_threads)
at ZeroMQ.ZmqSocket..Ctor(int32 type,Nullable 1 context)
at ZeroMQ.ZmqDealerSocket..ctor()
at ChatClient.Client.Main(string[] args) in c:\my Development\ZeroMq\ZeroMQ_ChatTest\ChatClient\Client.cs:Line 13
and the line 13 is refer to zmqDealerSocket dealer = new ZmqDealerSocket();
i'll try to download another .netframework .4

hi again . im sorry for bothering again .
im wondering why you didint use the router class instead of the dealer in the server class ?
im sorry but can you explain alittle about what you done here im new with zeromq but i know the basic , i know that that we need to define a new socket and connect the socket/listen i was doing this in past but now im seeing new things like dealer subscriber and publisher im wondering do they do the same things as the socket is do . but i'll appriciate if you just alittle explain what you done here . ty
|
|
|
|
|
I didn't use the router because it prepends each message with an integer connection ID. I used the client name to identify the client instead.
Honestly, there's not much point me explaining what I've done - my code is minimal. All of the information you need, and more, is in the excellent ZeroMQ documentation. Read the 0MQ Guide - all of the socket patterns are described in great detail in there. Also, looking at the code samples in conjunction with the 0MQ API would help.
I'm sorry if that sounds a bit like RTFM but...

|
|
|
|
no , is okay , ty very much . i've learned alot.
i'll figure it out soon or later .
ty again

hi my friend , im sorry for bothering you again .
just a simple qustion i have .
how should i do sth in the server side dealer.onrecived event . like lets say . close second form in that event(dealer.onrecived) before publisher.send() has executed .
i want to do that but it throw an error and saying :
Cross-thread operation not valid: Control 'Form2' accessed from a thread other than the thread it was created on.
i know that , when im start(run) a method with a thread , i should define a delegate and then invoke the object to access it .
but here i dont know how to access the object .
any help i'll apriciate that .

This is nothing to do with the question you originally raised, and I'm afraid I've helped you as far as I'm prepared to. I'm not going to write your application for you - it's yours not mine.
One final hint: UI operations from a background thread are not allowed. Both Google and CodeProject will give you more than enough information if you only look.

in the code i know for shure that i did get the data to my string sqlCity.but when the code come to adap.Fill(dt); it just jump to the catch.i try to do debugging but i did not find the reason why it not fill my dt datatable.can someone tell my what is the problem ?
public partial class test1 : System.Web.UI.Page
{
public SqlConnection myConn;
sqlDataAdapter adap;
public DataTable dt;
protected void Page_Load(object sender, EventArgs e)
{
string conn = @"Data Source=.\SQLEXPRESS;AttachDbFilename='"
+ Server.MapPath(@"App_Data\Database.mdf") + "';Integrated Security=True;User Instance=True";
myConn = new SqlConnection(conn);
try
{
myConn.Open();
string sqlCity = "select * from common";
adap = new sqlDataAdapter(sqlCity, myConn);
dt = new DataTable();
adap.Fill(dt);
}
catch
{
MessageBox.Show("Error.....");
}
finally
{
myConn.Close();
}
}
}
|

Use your catch clause properly to help you diagnose your problem; something like:
catch (Exception e)
{
MessageBox.Show("Error: {0}", e);
}
One of these days I'm going to think of a really clever signature.

i already try this and not found the problem .finally i found code that look the same and working
public partial class test1 : System.Web.UI.Page
{
public DataTable dt;
protected void Page_Load(object sender, EventArgs e)
{
string connString = @"Data Source=.\SQLEXPRESS;AttachDbFilename='"
+ Server.MapPath(@"App_Data\Database.mdf") + "';Integrated Security=True;User Instance=True";
string query = "select * from common";
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(query, conn);
dt = new DataTable();
try
{
conn.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
conn.Close();
da.Dispose();
}
catch
{
MessageBox.Show("Error.....");
}
}
}

So you copied your classmates solution.
There is an error in your original code so technically its not the same. Your new assignment is to find the difference and post it here

Hello everyone,
I have a problem, i want to use the following namespace
System.Windows.Int32Rect not exist
but i can't find it or it doesn't exist.
How can i obtain it.
Thanks in advance,
z3ngew
|
|
|
|
|
The solution of this problem is to add the
WindowsBase.dll from the references of the framework

|

|

This is not a namespace but a structure. Or to be more precise:
Int32Rect is a structure that has been placed in the System.Windows namespace. If you cannot find it then you are missing the WindowsBase library.

Which version of .NET framework are you using? According to the documentation[^] this was introduced in 3.0.
One of these days I'm going to think of a really clever signature.

I'm using .Net FrameWork 4
