I'm working in winform project.
I used a webbrowser in the form. The webbrowser load a html file with javascript. In the javascript, it can call external method use "window.external.???".
The cs code like this
[code]
namespace TestA
{
[System.Runtime.InteropServices.ComVisibleAttribute(true)]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
InitStart();
}
private void InitStart()
{
webBrowser1.Url = new Uri(AppDomain.CurrentDomain.BaseDirectory + "test.htm");
webBrowser1.ObjectForScripting = this;
}
public void TestB(ref int TT)
{
TT = 345;
}
public void Test(object TT)
{
object s = TT.GetType().InvokeMember("A", BindingFlags.SetProperty, null, TT, new object[] { "mynewvalue" });
}
}
}
[/code]
The html file like this
[code]
<script language="javascript" type="text/javascript">
function MyTestClass(){
this.A = "123MyTestClass";
}
var t = new MyTestClass();
window.external.Test(t);
alert(t.A);
//可以修改
var t = 123;
window.external.TestB(t);
alert(t);
//无法修改
</script>
[/code]

This is not possible; an exe file is compiled for a specific target platform. You need to make the source platform independent and then compile that source on each platform that you want to run it on, to create a compatible object.

How will that help to make a program platform independent?

He wasn't replying to the OP, he was replying to you. Perhaps he just thinks you want Reflector and have forgotten where it is now since Lutz sold it.

If you've written your application in .NET, then it's not platform independent. It will only run in Operating Systems that have the .NET framework. You could possibly compile against Mono, but that still isn't platform independent, for instance it won't run on an old VAX server.

You'll need a d compiler. Very few people here use d.

That's unachievable.

Hi -
I'm looking to automate the switching on/off of my 2nd monitor.
I can do it manually, via the Windows Desktop/Properties dialog. Is there a API or baseclass that can do this?
Any help is appriciated!

What is a recommended means of storing an expression/formula in a database field, to be evaluated at runtime in a report. The reporting Engine will likely be Telerik or SSRS. I have several production performance categories, measured in tons, count, percentage etc. that all must be able to have a unique formula for calculating the performance rating, in the appropriate unit of measure.
|
|
|
|
|
Write the expression in the database and during the evaluation of the formulas, use Infix to Postfix or Prefix and then evaluate.

What do you want help with? You haven't asked anything only made the statement that you copied someone else's work and can't figure out how to do it on your own.

Hi, Is there not a VB6 forum here? please direct me where to find it as my question is related to VB6.
I'm connecting client to server using VB6 Winsock Controls
'==========Server side============================
Winsock1.Protocol = sckTCPProtocol
Winsock1.RemoteHost = strParm(0)
Winsock1.RemotePort = 1002
Pause (7)
MsgBox "Before Connecting" 'just to do something, and give time to establish connection
Winsock1.Connect
MsgBox "After Connecting"
DoEvents
'Delay2 = 1
Pause (10)
Winsock1.SendData ("Starting dropship refresh...")
It works fine with the MsgBox between the Connect and the Senddata, but without it gives an error when firing Senddata method, seems because connection is not established quick enough.
Please help, how can I ensure connection before sending data?
I have tried some 'delay' processes which works 1 minute and doesnt the next.
Thanks in advance

VB6 has some rudimentary error-handling. Wait a sec, try to connect, and if it fails then try again in two seconds. Repeat for three to five times, and show a message that there's connectivity-problems if you cannot connect after that.
I haven't got a VB6-IDE at home, but this should give you a basic idea;
Private Sub WaitForAwhile(howLong as Int)
Dim currentTime
currentTime = timeGetTime
While (timeGetTime - currentTime) < howLong
DoEvents
Wend
End SubThis should allow a pauze while processing continues. Next, to the connection-routine;
Private Sub TryConnect()
On Error Goto myErrorHandler
Dim Tries%
Tries% = 0
TryAgain:
Winsock1.Connect
WaitForAwhile(1000)
Winsock1.SendData ("I will gladly beam down to the planet, Captain!")
Exit Sub
myErrorHandler:
Tries% = Tries% + 1
If Tries% < 5 Then
Goto TryAgain
Else
MsgBox "Cannot connect, try the sneakernet :)"
End If
End Sub

Hi Thanks Eddy,
I did put in some sort of delay similar to yours, it works the one minute and the next it doesnt, I even increased the time delay to maximum, but still same problem.
How can I get rid of this problem permanently.

Did you get an error-message of any kind? I can't debug from here, so I'm kinda guessing.
Perhaps you can let the application dump the contents of a ping (shell a command, "ping >C:\result.txt") to check connectivity if the loop fails five times.

I just had a look of some of my own code and found that every time, before I connect I follow the following logic:
(I cut out alot of irrelevant code such as error handling etc. so I may have made a mistake somewhere but you should get the general idea)
Sub AttemptConnectionToRemoteHost()
'(wsh is my client winsock control)
If wsh.State <> sckClosed Then
wsh.Close
End If
wsh.RemoteHost = RTrim(LTrim(txtAddress))
wsh.RemotePort = CLng(txtPort)
wsh.Connect
Await()
If wsh.State = sckConnected Then
'Report success!!
Else
'Report Failure
End If
End Sub
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Sub Await()
'Allow x seconds to for connection
Dim x As Long
Dim EndTime As Single
x = CLng(5) 'Allow 5 seconds for connection attempt
EndTime = Timer + x
Do
DoEvents
Loop While (wsh.State <> sckConnected) And (EndTime > Timer)
End Sub
This should do the trick for you. I found that, always checking that the port's state is sckConnected, before attempting anything with it, is a good failsafe. Use the Await() procedure above to ensure that the port is CONNECTED before continuing. You could bring the 5 seconds down to as little as 1 second for local LAN applications.

We have a transport class, one of the members is
private object _containerObject; with get/set methods. In our system this container object can contain every .net type, every class in our B.O layer, or a List<T> of those types, we also have a WebService with a method returning a transport class object, the problem is that this fails:
GenericTransportObject resoultGTO = new GenericTransportObject();
TestService.Service1 ourService = new TestService.Service1();
resoultGTO = ourService.WS_Input(gto);
The error I get is:
System.InvalidOperationException: The type BOLayer.UserInformation was
not expected. Use the XmlInclude or SoapInclude attribute to specify types
that are not known statically.
what happens in the web service is that the method creates a new GenericTransportObject, sets the metadata and set the _containerObject to a object of type UserInformation, and returns that object.
I get a message telling me to use XmlInclude or SoapInclude, but how do I do it, when the class I need to edit is a base class in a compiled .net assembly?
I hope I have explained the problem well (English isn’t my first language).

VS2008 and DotNet 3.5 with SP/1, on a 64-bit machine:
I'm trying to use registered window messages to communicate between applications. All apps/components are compiled to x86.
Here's my interop stuff (in a class library):
namespace Utility
{
public class WinAPI
{
public const string REGISTERED_MSG = "AllInOneDemo";
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern uint RegisterWindowMessage(string lpString);
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern int SendMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
public static int SendRegisteredMessage(uint message, int lParam, int wParam)
{
return SendMessage(IntPtr.Zero, message, lParam, wParam);
}
}
}
Here's my registering code:
private uint RegisteredMessage = WinAPI.RegisterWindowMessage(Globals.REGISTERED_MSG);
Here's my message sending code (the return value is always 0):
int result = WinAPI.SendRegisteredMessage(this.RegisteredMessage, 123, 456);
And finally, here's the message handling code:
protected override void WndProc(ref System.Windows.Forms.Message msg)
{
base.WndProc(ref msg);
if (msg.Msg == this.RegisteredMessage)
{
this.listBoxPublicMsg.Items.Add(string.Format("{0}\tLParam={0}\tWParam={1}", msg.Msg, msg.LParam, msg.WParam));
}
}
One application registers/sends the message, and one application is supposed to register/receive the message. The message is being sent, but it's not being received.
I have verified that both apps are getting the same return value when calling RegisterWindowMessage. The sending app appears to be sending the message, but the receiving app never sees it.
I tried using Spy++(64-bit) to look only at the Registered messages for both apps, but I get nothing at all for either window.
What am I doing wrong?
