Re: windows based schedular not working - Visual Basic Discussion Boards

Can't DeSerialize, but can Serialize with unknown object type :(

Hi,

Background:
Plugin Application.
TestPlugin.exe file is loaded into the main program using reflection. (this works)
Main program calls "ShowConfig()" plugin function using reflection invoke(obj, args),
and the plugin displays the config window,
user sets his config, clicks OK, window disappears
showconfig() passes back a reference to the "TestConfigObj" in the args
TestConfigObj is also public inside the TestPlugin.exe assembly.
Looking at the "args(0)" - it correctly shows the TestConfigObj.myconfigvars

Main Test program now wishes to take a clone of this "object"

BUT

this code is throwing this exception when I try and clone the "object",

<br />
  Function ObjectCopy(ByVal obj As Object, ByVal AssemblyFileName As String) As Object<br />
    'copies original object to stream then <br />
    'deserializes that stream and returns the output<br />
    'to create clone (copy) of object<br />
<br />
    Dim objMemStream As New MemoryStream(5000)<br />
    Dim objBinaryFormatter As New BinaryFormatter(Nothing, _<br />
        New StreamingContext(StreamingContextStates.Clone))<br />
<br />
    ' make sure our assembly is loaded!<br />
    ' System.Reflection.Assembly.LoadFile(AssemblyFileName)<br />
<br />
    ' output the object, reset pointer and input the object back again<br />
    objBinaryFormatter.Serialize(objMemStream, obj) ' *** THIS LINE(1) IS OK - Mouse hover shows ME ASSEMBLY BREAKDOWN OF 'Obj'<br />
    objMemStream.Seek(0, SeekOrigin.Begin)<br />
    ObjectCopy = objBinaryFormatter.Deserialize(objMemStream) ' *** THIS LINE(2) THROWS UNKNOWN ASSEMBLY<br />
<br />
    objMemStream.Close()<br />
end Function<br />

Exception:

<br />
System.Runtime.Serialization.SerializationException was unhandled<br />
  Message="Unable to find assembly 'CTPTestDemo1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."<br />
  Source="mscorlib"<br />
  StackTrace:<br />
       at System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembly()<br />
       at System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAssemblyInfo assemblyInfo, String name)<br />
       at System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] <br />
...<br />

However, when I hover the mouse over line(1) 'obj' I get:

<br />
- obj | { CTPTestDemo1.TestConfigObj }<br />
  - CTPTestDemo1.TestConfigObj | { CTPTestDemo1.TestConfigObj }<br />
    - Iterations | 12345<br />

I have tried loading the CTPTestDemo1 assembly just before I serialize, but this doesn't work
(hence why I have commented it out again)

Why can the mouse hover give me the correct "TestConfigObj" details, and serialize it,
but can't deserialize it back into the new object?

I have gone through the GetReferencedAssemblies() but the CTPTestDemo assembled is not listed in this collection.

I also only have ONE version of the CTPTestDemo assmebly (.exe file)

I do not want to reference in the MainApps References the TestPlugin.Exe Assembly - as these are test Plugin's and so the mainapp should not need to know about them

Any Ideas would be greatfully received!

Thanks,
Phil.

Hi,

I need to create a path for where my XML needs to be saved, but I need to get the path where the web files are saved on the server. In classic ASP I think I used Server.MapPath or something like that. The reason why I don't want to hard code is because certain hosting companies save the website on the C: drive, or f: Drive, etc.

Please can someone help? I'm using VB.NET 1.1.

You can handle a selected index changed event. How you handle it depends on if you want to write your record again for every field that changes, or if you want a save button.

Yes, it's possible, but only if the mother board supports it. Unless the mother board is willing to turn itself on, it's not really possible. Doing it via VB.NET will only work if the code is running on another machine, and the machine being switched on has mother board features that your code can access.

Unless your code drives a robot that pushes the power button.

Try docking your controls so that they maintain equal amount of form space.

You need to set the anchor property on your controls, so they size themselves automatically.
