Please help.
Where I can get a ToolBar for my Windows.Forms Application.
That toolbar should look like the toolbar in Visual Studio.
It should be able to move and dock to other sides of window.
Is there smth like that anywhere?

Hi,
I've started writing a program using version 1.0 of the framework, but now I would like to install version 1.1 and start using that. Do I need to do anything special with my application in order to get it to use version 1.1 of the framework instead of version 1.0 ?
Thanks

Depends on what tool you will be using to compile your app:
1. If you are using Visual Studio 2003, apps automatically use .Net Framework 1.1
2. If you are using Visual Studio 2002, then you have to create a config file. The config filename should be yourappname.exe.config, the location of the config file must be the same as the app's executable and the config file should contain the following lines:
<configuration>
<startup>
<requiredRuntime version="v1.1.4322" />
</startup>
</configuration>

Can some tell me where should I look to find differences between .NET 1.0 and .NET 1.1 ?
Thanks

I may be going slightly insane, but I have just installed VS.NET 2003 side-by side with my VS.NET 2002 installation.
I have compiled my remoting applications with VS.NET 2003 and they compile and (apparently) run fine -- but when I do System.Runtime.Remoting.RemotingConfiguration.Configure("server.exe.config") I get an exception informing me that there is malformed XML near the </configuration> tag.
I even tried putting a standard XML header in there but nothing changed.
Exactly the same config file works fine for the same code compiled under net1.0.
Am I doing something wrong, or has my mind finally cracked?
I'm going to sit in the corner and cry until someone helps me.

I am currently prototyping an application that will support plugin extensibility.
I figured this would be easiest achieved by allowing assemblies to be dumped in the application's directory and then having my application enumerate all the classes in those assemblies that support the IMyPlugin interface.
So far so good.
The problem I am having is in the instantiation of those IMyPlugin supporting classes.
None of these classes have a parameterless constructor because they must be provied with at least an identifying GUID when they are instantiated. I thought the following code would allow me to create one of these objects using the Activator.CreateInstance(a,t,p()) method.
However, I am having a hickup ... I get an exception at the Activator.CreateInstance line
"[System.MissingMethodException] Constructor on type MyDemo.Plugins.BasicPlugin not found"
Here is the code ...
---------------------------------
Namespace MyDemo.Plugins
Public Class BasicPlugin
Implements IPlugin
Public Sub New(ByVal guid As System.Guid)
MyBase.New(guid )
End Sub
...
End Class
End Namespace
... And in another class this function tried to instantiate it ...
Public Function NewPlugin(ByVal pluginAssembly As String, ByVal pluginType As String) As IMyPlugin
' These are the parameters to pass to the tasklet constructor.
Dim constructorArgs As Object() = New Object() {_GUID}
' Instantiate the tasklet class.
Dim myDynamicallyLoadedPlugin As Object = Activator.CreateInstance(pluginAssembly, pluginType, constructorArgs).Unwrap()
' Cast the tasklet object to a Task type.
Return CType(myDynamicallyLoadedPlugin , IMyPlugIn)
End Function
---------------------------------
I would really appreciate any suggestions that help me resolve this. In the meantime I have added a static "factory" method to the BasicPlugIn class that creates returns a new BasicPlugIn object, but this is not as ellegant and I am feeling quite defeated.
TIA

You shouldnt be Unwrapping it, thats for remoting!

I am looking for suggestions on how to do something described below:
- a web service that will be called by a web application about 200,000 times in a 15-minutes interval.
- Each call will generate a string of data that needed to be recorded to the central database.
Someone suggested to me:
- the data generated by each call should temporary be sitting in memory.
- A timer should wake up periodically to push the data to a queue, before the memory is too full.
- The queue will write the data to the central database at a daily scheduled time.
I would like to get some idea of what technique / technology that I can use to implement those suggestion., and to make the web service efficient.
I am new to .NET and MS technology. I hope that someone can just point me to some directions and will be very much appreicate.
Thanks.

200,000 times in 15 minute intervals? Are you sure you really need to use a webservice for that? That is 200,000 HTTP requests and responses. Plus all the SOAP packaging, serialisation of the data, deserialisation, authenticating... At the least I know one IIS box is not going to come anywhere near handling that. You could optimise the data factory to hell and back but it is the IIS and webservice part that will tank.
Why does it have to be 200,000 transactions? Can you not send more data with fewer transactions?
I just think that no amount of in-memory storage, "queuing of memory" etc. ideas will help. The database could handle the writes easily enough, but not IIS.
Maybe you can explain what you are trying to do and we can come up with a better architecture and set of technologies for this

Actually 200,000/15 minutes is the total hits in the peak time of the day for a farm of 6-7 servers.
We are a brokeage firm that offers on-line quotes to clients. We would like to log the usage.

That is better. Also I misunderstood you originally, I thought you meant every 15 minutes you get 200,000 requests. Not 200,000 per 15 minutes

Ok. Well if I think of anything I will post.

What if you use a message queue through, say, MTS; the webservice creates a message on the queue, then forgets about it. You could create a service somewhere else that listens for messages on the queue and processes them accordingly.

I feel you can use the MSMQ of Microsoft.. to log into it.. (From the webservice)..Now write a bunch of message handlers..(exes /windows service) that keep pulling out messages from the queue and write into DB..
This might work.

I've tried using the Register property of a deployment project, it works fine for COM components, but for Assemblies, I've tried vsdraCOM and vsdraCOMRelativePath, neither seems to do anything. No tlb file is generated, and no entry in OleView. I've tried registering through Custom Action, but the problem is in Uninstall, you can't use custom action because the dll's are deleted before any custom action is run which could unregasm. Has anyone dealt w/installing assemblies needing to be regasmed?

These two settings only do any magic if the assembly is designed to work through a CCW (Com Callable Wrapper). Basically, if you have designed your assembly to be a <gasp> COM component.
I have used these settings with success. I found a great .NET pdf library that I needed to use in VB6, so I wrote a wrapper object that looked like the VB6 printer object. Using attributes to control the visibility of my properties and methods, then using CCW to expose the object to the COM world. Worked great. 
In the project properties of your source project (Not the deployment project), check the "Register for COM interop" to get the TBL built, etc.
Also, using the various attibutes can make your assembly look much better to those COM eyes...
<br />
Imports System.Runtime.InteropServices<br />
<br />
' Expose this object as a COM object<br />
<ClassInterface(ClassInterfaceType.AutoDual), Guid("07C9F63C-4776-49d1-9D12-BB0AF62FC6F2")> _<br />
Public Class PDFPrinter<br />
' Content Goes Here<br />
End Class<br />
Then, in the deployment project...
[cPDFWriter.tbl]
Register=vsdrfCOM
[cPDFPrinter.dll]
Register=vsdrfCOM

Anyone been able to do this?
I can do it, but I cannot connect to the solution file form a remote machine (get told that the solution file is invalid).

Webservice NOT in wwwroot..
Well, I have never made a webservice that WAS in the wwwroot. By defualt VS.NET puts it in a sub-folder. Is there a typo in your question?

That's really what I meant 
I wanted to run 2 web sites on one bok so I set up another root folder named 'webroot' and set up all the host headers and stuff for it that way.
I even assigned another IP address to my NIC and set up an entry in DNS to point there, then bound that site ot that IP address.
Every time I try to use VS.NET to open a site in a sub folder of the second root folder I am toild that I can't.

Perhaps reinstall the .NET fx, only takes a few minutes.

Hello,
"generic error occurred in GDI+. at System.Drawing.Bitmap.GetHbitmap(Color background)
at System.Drawing.Bitmap.GetHbitmap()
at MyAssembly.Engine.Resources.GetPatternHBitmap(Int32 patternId)"
Does anyone know what this error means?
More info:
My method GetPatternHBitmap() gets a Bitmap from my resource assembly:
<br />
Bitmap b = GetPatternBitmap(patternId); <br />
Then, the error occurs at
<br />
IntPtr ip = b.GetHbitmap();<br />
TIA.
