Late Bound Assemblies and SoapFormatter.Deserialize problem... Chris Richner19-Dec-04 14:53 Chris Richner 19-Dec-04 14:53  Hi, Basically a Command is nothing else than a Plugin, should mean that i would like to be able to write Commands which implement the ICommand interface and are stored in different assemblies, which are loaded at run time through a type loader. I have a collection of Command's, let us call it my project file which i serialize trough the SoapFormatter. So, now we have a project file which holds a command configuration set, now i would like to load this file again (later), but now it happens... First i run my TypeLoader which loads the needed assemblies into the current AppDomain. Then my code tries to deserialize the soap file, it throws an exception saying that the needed assembly/type is not found, but ermz, my TypeLoader loaded the needed assembly... Any hints? In my opinion it should work, because all assemblies are loaded during Deserialize, it's the same game like Serialize myMsg.BehindDaKeys = "Jerry Maguire"; Re: Late Bound Assemblies and SoapFormatter.Deserialize problem... Daniel Turini19-Dec-04 17:13 Daniel Turini 19-Dec-04 17:13  If I understood correctly, you aren't able to deserialize some previously SoapFormatted objects. Without some code, it's hard for us to guess what's wrong, but the most common serialization problem I see here is versioning, which can be solved by setting the AssemblyFormat property of the SoapFormatter to FormatterAssemblyStyle.Simple before serializing.

Chris Richner19-Dec-04 22:25 Chris Richner 19-Dec-04 22:25  Hi Daniel, I made shure that my assemblies always ware the same version number, no auto increment build numbers.

Items elements vary. Thanks Re: dynamically create multiple controls Heath Stewart20-Dec-04 6:28 Heath Stewart 20-Dec-04 6:28  The same way as you would a static number or as the designer does it (take a look at your code-behind source file sometime for a Form or UserControl: for (int i=0; i<listBox1.Items.Count; i++) { ProgressBar pb = new ProgressBar(); Controls.Add(pb); // Set properties for <code>pb</code>. } This posting is provided "AS IS" with no warranties, and confers no rights. Software Design Engineer Developer Division Sustained Engineering Microsoft [My Articles] [My Blog] problem with extender provider esakal19-Dec-04 4:01 esakal 19-Dec-04 4:01  Hello, i have a problem, it is a bit long explenation but please help... this is very very annoying problem. i created a component the implent the IExtenderProvider. I have "binding" property which saves information of controls in an HashTable. since the binding is a class, i use "ExpandableObjectConverter" to convert the value from string to object When i add the binding propery to a control in a form, it seems to be fine. BUT when i move to the "cs" file to see how it was added, i get the following error in the "task list" : "code generation for property Binding failed. Error was: 'key cannot be null. Parameter name key'" !? the cs files remains as is without any modifications. i tried to debug the design-time and saw that the values are added to my hashtable. offcurs not while run-time (it makes sense since nothing is being added to the cs file). i don't have such a property named "key"... Eran Sakal. code attached : [Category("Data"), Description("Define DataBinding on object")] [DefaultValue("")] public Binding GetBinding(Control extendee) { if (m_bindingCol.Contains(extendee.ID)) return (Binding)m_bindingCol[extendee.ID]; else // if not exist, create default value which is not added to the hash table { Binding binding = new Binding(null); return binding; } } public void SetBinding(Control extendee, object value) { Binding binding = value as Binding; binding.Control = extendee; if (binding.ObjectProperty == null) m_bindingCol.Remove(extendee.ID); else { // set default controlproperty if null if (binding.ControlProperty == null) binding.ControlProperty = (extendee is CheckBox) ? "Checked" : "Text"; if (binding.ObjectType == null) binding.ObjectType = m_boundType; // add to collection if (m_bindingCol.Contains(extendee.ID)) m_bindingCol[extendee.ID] = binding; else m_bindingCol.Add(extendee.ID,binding); } } Re: problem with extender provider Colin Angus Mackay19-Dec-04 10:03 Colin Angus Mackay 19-Dec-04 10:03  Key is probably the indexer into the hashtable. I am guessing that the extendee.ID is null. Do you want to know more?

Thanx Re: How can i know which form are activated? Heath Stewart20-Dec-04 6:12 Heath Stewart 20-Dec-04 6:12  Do you want to know which are open or which are active, because there's a difference? Only one top-level window can be activated on the entire desktop at a time. If you want to get the active form in your application, then use the static Form.ActiveForm property. If you want to know which windows are open, then you need to track your Form variables. This posting is provided "AS IS" with no warranties, and confers no rights.

Is there any way for users to access these without having the directx sdk installed? thanks Re: Finding dlls Colin Angus Mackay19-Dec-04 2:46 Colin Angus Mackay 19-Dec-04 2:46  thepersonof wrote: Basically on computers with directx 9c sdk installed there is a Microsoft.NET/ManagedDirectx directory in the windows directory which contains the directx dlls. Is there any way for users to access these without having the directx sdk installed? What to you mean by "access"? If the files are on disk then yes, this folder has no special permissions on it. If you need Managed DirectX to be on the system for your application to run then you need to install the DirectX redistributable with your application. The SDK is a Software Development Kit which has additional aids and documentation for developing software which your end users do not need. If this is what you mean the link I gave in my previous post will help you find the redistributable package. Does this help? Do you want to know more? WDevs.com - Member's Software Directories, Blogs, FTP, Mail and Forums Re: Finding dlls thepersonof19-Dec-04 2:52 thepersonof 19-Dec-04 2:52  my application is to be used for the creation of 3d graphics and also of presentations. Therefore in order to compile these dlls are required. In other forums it has been suggsted that they are in the GAC, would I find them thereor would I have to distribute thm myself?

Compiling the application is something that the developer does. The user does not need to compile the application as they receive it in the compiled state. The compiled version will need the appropriate assemblies to be available to it. This is why you need to redistribute the Managed DirectX assmeblies as you are not permitted to supply the SDK. thepersonof wrote: In other forums it has been suggsted that they are in the GAC, would I find them thereor would I have to distribute thm myself That is correct. You therefore need to supply the Managed DirectX redistributable with your applicaction. Its installer will make the appropriate checks and install itself if necessary. Does this help?

My program compiles 3d graphics and presentations, that is what the problem is, not redistributables, etc which I am perfectly competent with. Thanks for trying though. Re: Finding dlls J4amieC19-Dec-04 7:49 J4amieC 19-Dec-04 7:49  If you are competant with redistributables, then where is the problem distrubitng the DirectX SDK with your 3d compiler application? Re: Finding dlls thepersonof19-Dec-04 8:17 thepersonof 19-Dec-04 8:17  Its 200+ mb! Re: Finding dlls Colin Angus Mackay19-Dec-04 10:00 Colin Angus Mackay 19-Dec-04 10:00  What is wrong with that. You are creating a compiler with associated IDE (and one presumes documentation). My Visual Studio install is in excess of 1Gb (more if you include the MSDN library) If your compiler is allowing its users access to the Mangaged DirectX APIs then I cannot see a problem with distributing the SDK (license permitting). If you are providing a layer of abstraction so that your users do not need to know anything about DirectX then you will be able to get away with the redistributable. Do you want to know more? WDevs.com - Member's Software Directories, Blogs, FTP, Mail and Forums Re: Finding dlls J4amieC19-Dec-04 12:16 J4amieC 19-Dec-04 12:16  So what you are *really* asking, is "Can users of my app use all the cool features of DirectX without the 200 Mb install." - and the answer should be obvious to any developer.* The pros and cons of this argument are the same as with the .NET re-distributable, and there are many topics here and many other places on this exact subject. * Some redistributables can be broken down to core components, which tends to be alot smaller than the setup executable, you may want to investigate if this is an option with managed DirectX Compiling MSIL and c# thepersonof19-Dec-04 0:33 thepersonof 19-Dec-04 0:33  Hi Is there a way to add MSIL to c# code?
