    - Typed datasets and table table adapters components not showing in Typed datasets and table table adapters components not showing in Toolbox Hi, I have a solution with several projects. One project contains datasets with table adapters. When I opened a usercontrol in design mode, it used to have all datasets and tableadapters in toolbox, under a tab name with the name of the datasets project However, I had to upgrate to a new hdd, and did a clean Windows install, with VS2005, etc Now, when I open te solution and open a usercontrol in designer, I see only the other user controls, but no datasets or table adapters as I used to have before. Sometimes I see a tab with the name of the datasets project, but on it there is a text telling "There are no usable controls in this group" What happend? I mention, on old HDD I had instaled VS2003 and VS2005, on new one I have only VS2005 and installed VS2008 express, but then I removed it (as I thought maybe it caused the issue). I even uninstalled and reinstalled VS 2005, with no luck. Can anyone help me with this? Thank you Tag: CAS, WPF & plugin question Tag: 137949

    - Tab and Ctrl+I in a richtextbox Hello, I program a user control which display a RichTextBox and a format ToolStrip. I want to process some shortcut keys. The RichTextBox accepts tab. Ctrl + I is supposed to format the selection in italic. But Ctrl+I is also de code for Tab. So when I press Ctrl+I, a tab is inserted (replacing the current selection) AND the new selection is formatted in italic. How can I do this ? Do I have to inherit first the standard RichTextBox and override the OnKeyDown method ? -- Fred foleide@free.fr Tag: CAS, WPF & plugin question Tag: 137942

    - Syntax Difference C#/VB.NET when calling a Method Hi. I'm a VB.NET developer learning C#, and I have a simple syntax question. In C# whenever you invoke a method you need to include the parentheses () after the method name even if there are no parameters. In VB.NET you don't have to do this. For example - IDataReader oReader; while (oReader.Read) //This will throw an exception while (oReader.Read()) //This is the correct way. I'm just curious why C# requires this but VB.NET does not.

    - web deployed assembly I have a windows forms assembly that needs to be deployed via a webpage. This bit of code must provide a fully automated printing solution; in that it must accept a parameter containing a graphic image to print, and print it without any interaction. The issue I'm having is that it throws a security exception [Request for permission of type: System.drawing.printing.printingpermission ... failed]. This bit of code seems to work just fine if I use the print dialogbox and select the appropriate printer, and of course fails if I don't use the dialogbox. This seems to be a security issue, but I'm not sure where to look, or how to fix it. And, so as to head off a couple of other issues; I need to pass a parameter to it from the HTML page, and it has to be served by Linux. Thanks. Tag: CAS, WPF & plugin question Tag: 137919

    - is there difference between XP Pro and Server2003? Hi, my local machine is XP Pro. when I built the WCF hosted in IIS, it works fine. (create virtual directory on IIS and open that website and coding.. that's it.) but When I try to built the WCF hosted in IIS in server machine, it causes error. (create virtual directory on IIS and open that website and coding. same with xp pro) my server machine is Server2003. After I publish this on the different location in server2003 IIS, it works fine. Do I have to publish the WCFservice? Is there difference between XP Pro and Server2003? When I publish this, I have to be very careful since they just clean that folder automatically.

    - Does HttpListener have the same quirk as HttpWebRequest Hi... We've implemented a server process using HttpListener to get and process certain requests, but we've been noticing some odd serialization that reminded me of a quirk in the client code. We recently discovered an odd behavior of HttpWebRequest in the client code where mixing sync and async methods resulted in everything quietly being sync. Specifically, we were using GetRequestStream() to send the data up synchronously then calling BeginGetResponse() to wait for the answer async. Well, it turned out that if you call a sync method first the async calls magically turn into synchronized ones - a rather undocumented behavior. Now we're seeing some similar quirks on the server side with HttpListener. We use BeginGetContext() to listen for a request. Our callback calls EndGetContext() to get the details and then immediately calls BeginGetContext() again to wait for another request. But then we read the request synchronously, post the work in a queue with the associated response object and move on. What we're seeing is that if the client sends several requests in a row, it blasts right through them but the server doesn't acknowledge even reading the 2nd request until after the response to the first request is written to and closed. Does HttpListener have some implicit serialization behavior like HttpWebRequest? Thanks Mark Tag: CAS, WPF & plugin question Tag: 137904

    - Any CPU assemblies, Framework64, and Process Explorer Hi... We're building our assemblies Any CPU and just now trying to throw them up on an x64 box. I was using Process Explorer to look at something else, and I noticed something peculiar. All of our assemblies were in the Framework64 temporary assembly cache for the running process but Process Explorer had flagged them all as being 32-bit code. Is this a quirk of Process Explorer not having a mind-meld of the .Net framework and understanding how the code is being executed, or is Process Explorer right and it's running in 32-bit mode, despite where it's running from?

    - New Information on Error 1603 when installing .NET Framework all I was having major issues with installing Visual Studio 2008 on my computer. In particular the .NET 3.5 component required to run Visual Studio 2008. I tried everything that was online from editing registry settings, setting access permissions and all. I was able to install up to .NET FW 2.0 but past that I kept getting error 1603. This error is usually an access error telling the user that the target drive, folder or file is unaccessible. I found when doing a verbose log with the install the Microsoft IIS installation on my computer was corrupted and I needed to reinstall IIS on my computer. The best fix for this issue is 1st: Uninstall the IIS server off of the computer. 2nd: Run the .NET FW 3.5 Installer 3rd: Re-Install IIS from the Windows CD-ROM. 4th: I was then able to install Visual Studio 2008 on my computer after fixing this. I hope this helps everyone out and sheds some light on installing. Tag: CAS, WPF & plugin question Tag: 137902

    - Batch of Stored Procedures In our .Net 2.0 web service we need to insert/update data records into SQL Server 2005 that have been uploaded to us in XML documents. There could be anywhere from one to literally thousands of records in each uploaded transaction, and there are several dozen destination tables. Since performance is critical for this particular app, we were thinking of combining the stored procedure calls into configurable- sized batches using CommandType.Text and multiple concatenated EXEC statements, so we minimize database roundtrips as opposed to calling each SP individually in its own SqlCommand. Is this a good approach? One concern is that SQL Server would have to compile each and every batch since they will all be different, and the overhead involved in this could become significant. Is this really something to worry about, or not? Wouldn't a few batch compiles per transaction still be better than potentially thousands of roundtrips? Are there other problems with this approach? Of course we are planning to stress test to see how it actually responds, but I just wanted to get some opinions first in case someone has done this before and can give advice/recommendations/suggestions before we get too far into it.

    - Generic Dictionary Serialized with Xaml I'm having some troubles with Xaml as a serialization option. The problem lies in serializing nested Generic dictionaries: Basically, I see different XML if the first element of the dictionary's values is a primitive versus if it is another dictionary. If the first element is a primitive, I get an extra layer of XML tags (I say extra, but, they do seem to be neccessary). If the first element is not a primitive, those tags are missing and the XamlReader cannot read the output Xaml back in.. Here's a simple test case: namespace WpfApplication1 { public class MyDictionary : System.Collections.Generic.Dictionary<string, object> { } public class UseMyDictionary { public UseMyDictionary() { MyDictionary = new MyDictionary(); } private MyDictionary _myDictionary; [System.ComponentModel.DefaultValueAttribute(null)] public MyDictionary MyDictionary { get { return _myDictionary; } set { _myDictionary = value; } } public static void STRANGE_CASE() { UseMyDictionary use = new UseMyDictionary(); use.MyDictionary["b"] = true; Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:s="clr- namespace:System;assembly=mscorlib" xmlns:assembly="http:// schemas.microsoft.com/winfx/2006/xaml"> <UseMyDictionary.MyDictionary> <MyDictionary> <s:Boolean assembly:Key="b">True</s:Boolean> </MyDictionary> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ use.MyDictionary["c"] = new MyDictionary(); Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:s="clr- namespace:System;assembly=mscorlib" xmlns:assembly="http:// schemas.microsoft.com/winfx/2006/xaml"> <UseMyDictionary.MyDictionary> <MyDictionary> <s:Boolean assembly:Key="b">True</s:Boolean> <MyDictionary assembly:Key="c" /> </MyDictionary> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ use.MyDictionary["a"] = new MyDictionary(); Console.Out.WriteLine(System.Windows.Markup.XamlWriter.Save(use)); /* <UseMyDictionary xmlns="clr- namespace:WpfApplication1;assembly=WpfApplication1" xmlns:assembly="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib"> <UseMyDictionary.MyDictionary> <MyDictionary assembly:Key="a" /> <s:Boolean assembly:Key="b">True</s:Boolean> <MyDictionary assembly:Key="c" /> </UseMyDictionary.MyDictionary> </UseMyDictionary> */ } } } Tag: CAS, WPF & plugin question Tag: 137818

In order to build a Hash Provider I must specify a 'Type that implements Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.IHashProvider.' When I go to specify this value it prompts me to find an assembly on my computer that implements this. What exactly is this and how can I determine which assemblies can be used in this situation to implement a Hash Provider? If this is the incorrect forum for this type of question please direct me elsewhere. Thanks! Mike Tag: CAS, WPF & plugin question Tag: 137816

    - How to use VS Unit Test where code uses a BackgroundWorker A feature I want to test calls a BackgroundWorker. How do I use Visual Studio Unit Test to do this? I can see why the callback method DoWork_Completed (in the sample below) is NOT reached during when running Test1. Is there a way of achieving this? <TestMethod()> Public Sub Test1() Dim txn As MyTransaction = New myTransaction txn.DoWork(AddressOf Me.DoWork_Completed, someParameters) End Sub Private Sub DoWork_Completed(ByVal results as DataSet) Assert.AreEqual(results.SourceInfo.Rows(0).Item(0),"X") End Sub (BTW My UI application invokes a BackgroundWorker when making a call to a SQL Server stored procedure to get data for a user to view. Using a BackgroundWorker allows the user to, for example, cancel viewing the data and do some other UI task. So this seems a common-ish thing to want to do and test) Tag: CAS, WPF & plugin question Tag: 137809

    - how separate fast unittests from slow acceptancetests in VSTS? Hello all, I am used to work with NUnit where I can very easily separate slow tests from fast tests. I simply create two projects: AcceptanceTests and UnitTests. If I only want to execute unittests I run that project only. How can I achieve this in VSTS with the new artifacts like testrunconfig, vsmdi-files and testlists? Thanks in advance! /Rasmus Tag: CAS, WPF & plugin question Tag: 137807

    - Print To File I need to print to disk with a dynamic output filename. I have read some material that would seem to indicate that the way to do this is to use the Microsoft defined DOCINFO structure and the StartDoc function in the Win32 API. I have checked my Win32 API Bible and found no such reference. Q.1 - Is this the best approach? Q2 - What would the code look like? Tag: CAS, WPF & plugin question Tag: 137801

    - Getting CSharpCodeProvider to use .NET 3.5 I have a .NET 3.5 app (built using VS2008 RTM, no CTPs installed) that uses CSharpCodeProvider to compile some generated code that requires .NET 3.5. When I set the compiler's .NET version to 3.5 (per the MSDN example), I get a "csc.exe not found" exception thrown when I try to compile. Here's what I'm doing: // Set up compiler parameters CompilerParameters cp = new CompilerParameters(); cp.xxx = xxx; // Specify .NET version Dictionary<string,string> providerOptions = new Dictionary<string,string>(); providerOptions.Add ("CompilerVersion", "3.5"); CSharpCodeProvider codeProvider = new CSharpCodeProvider (providerOptions); // Do the compile string sourceCode = "..."; CompilerResults cr = codeProvider.CompileAssemblyFromSource (cp, sourceCode);If I use CSharpCodeProvider's default constructor, the code compiles if it's .NET 2.0 compliant, but (expectedly) generates an "unknown reference" error if I try to reference a .NET 3.5 stock assembly. A nudge in the right direction would be appreciated. Thanks! /ravi Tag: CAS, WPF & plugin question Tag: 137798

    - Searching for SerialPort class alternative I have problems with .NET framework SerialPort class. First I had problems with data received event. Than I have changed form event to thread which checks for data every 100 my. Now after a while the components stops receiving characters. I suspect that the problem is in framework and because to verify this I would like to know if someone could give me me a hint of alternative class that could be used for serial port communication. I do need simple class that would support: - opening and closing serial port - sending string - data received event and data read Best regards Simon Tag: CAS, WPF & plugin question Tag: 137796

    - Isolated storage I am building a vb.net app that needs to interact with various COM controls that use docfiles to store their data. Not knowing much about isolated storage at this point, if I create a store and add some directories, can the COM objects create files, etc in these directories, or in other words will StgCreateStorageEx, etc work ok if passed the path of the directories created earlier? Another way of asking the question is whether there is something mysterious about isolated storage or whether this is just a mechanism for setting up what are ultimately just normal directories and files that can be got at by unmanaged code? -- JB Tag: CAS, WPF & plugin question Tag: 137794

    - DNS server override for application Hi, I've got an application that heavily uses .NET HTTP functions, that in turn use DNS resolves - I would like to make my application use specific DNS servers that happen to be more reliable in terms of resolves than average consumer grade network setup, the question is whether it is possible at all in a .NET app without moving away completely from build-in HTTP library?

In my application I am able to load plugins, i.e. use reflection look in an
assembly for classes implementing a given interface and instantiate them.

I would like these plugins to run with restricted right.
Like they are not able to access the file system, etc....
How could I do that?

Also, from some prelimiary reading it seems I will have to run thess plugin
in different AppDomain, but these plugin need to create some WPF.Controls
I'm adding to my main form's visual tree hierachy.
Is it possible to do that? I mean add in the UITree a WPF.Control which is
from a different AppDomain?
(I foresee a dispatcher problem)

Any tip? (or maybe I don't need to run my plugin in a different AppDomain
after all?)
