    - Missing Method Exception (REALLY Weird!!!) PLEASE HELP I created a scripting engine that accepts source code, source language, and various other properties that specify imports, references, and such. Then, I created a ScriptPanel that allows editing of all this data, with a drop down for the language, list boxes for the imports and references, and a highlighting textbox for the script itself. Next, I inherit from the scripting engine to create custom scripts. These custom scripts contain properties such as RequiredMethodName, RequiredMethodParameters, and RequiredMethodReturnValue to clarify how they should be written, so that consumers of the custom script know what and how to call into the script. Likewise, the ScriptPanel contains these same properties such that the panel can be assigned the values from the custom scripts. In this way, the panel can test whether the requirements are met in the edited script. Seems logical, right? Well, the properties on the custom scripts and on the ScriptPanel are like so: Public Property RequiredMethodName() As String Public Property RequiredMethodParameters() As System.Type() Public Property RequiredMethodReturnValue() As System.Type Notice that the types of these properties are "System.Type" and an array of "System.Type". However, this is apparently not allowed, though I can find no documentation that says so. Whenever I compile, I get no errors. Even the background compiler does not give me any squigglies, and IntelliSense shows the correct property signatures. However, whenever I actually run the application, whether in debug mode or by launching the compiled EXE, I get the following error: System.MissingMethodException: Method not found: Void ScriptPanel.set_RequiredMethodParameters(System.Type[]) Well, that doesn't make any sense! The property is right there. How can it not be found? In the code editor, even when I right-click and select Goto Definition while on that property, it takes me right there to the code or to the Object Browser, depending on how I reference the project containing the ScriptPanel (I've tried it both ways). So, I thought, maybe it doesn't like properties of type System.Type or arrays of System.Type. (I also tried just with the single System.Type, commenting out the array, and I get the same error, albeit with a different method name.) So, I changed the properties to pairs of Set/Get functions like so: Public Function GetRequiredMethodParameters() As System.Type() Public Sub SetRequiredMethodParameters(ByVal parameters As System.Type()) Again, I get the following error: System.MissingMethodException: Method not found: Void ScriptPanel.SetRequiredMethodParameters(System.Type[]) WHAT??!! I just created that function. There it is right there! What gives? Can you just not pass System.Types around? That would be very strange if so, and no where can I find that this practice is not allowed. And if it is not allowed, I am totally screwed because I need to pass types around. Passing strings around might work, but then developers and script writers are going to have to fully qualify everything all the time. Not gonna happen. :) I have changed properties to functions, the names of the functions, putting the ScriptPanel in another namespace, the names of parameters, everything. The only thing that fixes this issue is removing System.Type and arrays of System.Type. Even when I look at the DLL with ILDASM, it shows the properties or functions as being there. Yet, at runtime, it cannot find them. Can someone please explain this to me? There seems to be something really wrong here and it is driving me bonkers. Tag: Doing "&&" in codeDOM Tag: 93920

    - fill DataSet using OleDbDataAdapter from Access field format is lost I have an Access database that has an input mask on a field, !\(999") "000\-0000;0;_ , that formats a phone number. When I fill a DataSet using an OldDbDataAdapter some of the records lose the formatting. For example: Sam Jones (999) 555-1212 *this is good* Joe Smith 9995551212 *this is bad* Why would some records lose the formatting? There is no rhyme or reason (that I can see anyway) why some records keep the formatting and some lose it. Thanks in advance for the help and plese let me know if you need any more detail.

    - Split - not like perl? Hello, I am trying to use string.split to break up a string into fields. It seems as though, when using space as a delimiter, the method fails to perform as desired when more than one space delimits two fields. Am I interpreting this correctly? In perl, the following string: "this that and the other thing" would split into 6 elements. The .NET makes a fields for each space? Is there a way to handle this (other than regular expressions?)

    - HttpWebRequest and Host header Hi... I've been working a bit with the HttpWebRequest class and one requirement I've gotten recently is the desire to set the HTTP Host: header separately from the specific machine referenced in the url. For example, the url http://frontend1.east.company.com but passing Host: www.company.com to emulate a call to the general front door. I look in the HttpWebRequest documentation on MSDN, and under the Headers property, it says specifically that the Host header's derived from the url (implying that it can't be overridden). Is there any way to do what I want to do? Thanks _mark Tag: Doing "&&" in codeDOM Tag: 93896

    - Socket Class Slower Then HTTP Web Request I developed an application that automates dwonloading of a web page hundreds of times. I first developed it by using http web request, but then I read up that HTTP Web Request has some overhead that I thought I could eliminate if I re-wrote it with sockets. However, what I have found is that sockets actually works significantly slower (I get about 1/2 to 2/3 of the performance I get with HTTPWebRequest). Now, the web server sends a close command on every request so even if I post a Keep-Alive request I have to create and open a new socket for every request, but I assume the HTTPRequest class must do the same thing under the covers. Below is my Socket Send Method (very basic). Can anyone explain this strange disparity in performance? public string Send(string strRequest) { m_sock = new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp); m_sock.Connect(ipe); string strRetPage = null; Encoding ASCII = Encoding.ASCII; Byte[] ByteGet = ASCII.GetBytes(HttpRequest); Byte[] RecvBytes = new Byte[256]; m_sock.Send(ByteGet, ByteGet.Length, 0); Int32 bytes; do { bytes = m_sock.Receive(RecvBytes, RecvBytes.Length, 0); strRetPage = strRetPage + ASCII.GetString(RecvBytes, 0, bytes); } while (bytes > 0); m_sock.Shutdown(SocketShutdown.Both); m_sock.Close(); return strRetPage; } Tag: Doing "&&" in codeDOM Tag: 93882

None of which worked for me. I am using Version 2003 of Visual Studio .NET. SOLUTION: You can't name your Dataset the same as your table name that will be in the dataset or you will get this error.

    - Cross AppDomain Communication, Scripting Howdy All, I am having difficulty with two-way communication across AppDomains in an attempt to dynamically script applications. Everything works as expected, except when using ByRef parameters. The below explanation is lengthy, but well worth the read. If you can help me, I'd gladly share this code which has greatly helped my development of extensible applications. I have developed an easy to use scripting engine for .NET that handles loading and unloading of a secondary AppDomain automatically. I call the object "SafeScriptingEngine", and it has properties for the source language, source code, and any needed references and imports. When its compile method is called, the code is compiled by the appropriate compiler, then it creates a new AppDomain, loads the compiled code into the AppDomain, and uses a Class Factory approach to return a well-known interface. This simple interface contains two functions called "MethodExists", which accepts a function name and a list of parameters then return a Boolean of whether the function exists, and "CallMethod", which again accepts a function name and a list of parameters then actually calls the function. Public Interface IRemoteLoader Function Invoke(ByVal methodName As String, ByVal parameters() As Object) As Object Function MethodExists(ByVal methodName As String, ByVal parameters() As Object) As Boolean End Interface So, an example of using this engine looks like: Dim sse As New SafeScriptingEngine() sse.Language = Languages.VisualBasic sse.SourceCode = "" & _ "Public Function UpperString(ByVal s As String) As String" & _ " Return s.ToUpper" & _ "End Function" If sse.Compile() Then If sse.MethodExists("UpperString", New Object() { "" }) Then MsgBox(sse.CallMethod("UpperString", New Object() { "this string will be converted to uppercase" })) End If End If All of this works great. There are no memory leaks, and all compilers, AppDomains, and assemblies are unloaded as desired and expected. In fact, I designed the engine to be inheritable such that functions can be created that are strongly typed. As you can see, the default engine expects a non-strongly-typed array of Objects. To prove the usability of the engine, I created a "SimpleStringScript" which inherits from the "SafeScriptEngine". The "SimpleStringScript" accepts only the part of code that does the manipulation, such as "s.ToUpper" in the example above. In the background, it adds function, parameters, and Return statement. Also, with the "SimpleStringScript", there is no need for "MethodExists" that accepts parameters. Instead, it has a "StringMethodExists" function that accepts no parameters, which then calls "MethodExists" on the base "SimpleStringScript" with a String Object as the parameter. Likewise, there is no need to call "CallMethod" with a function name and Object array. Instead, it has a "CallStringMethod" function that take a String as a parameter, which in turn calls the base "CallMethod" with the appropriate function name and the String parameter encased in an Object array. Public Class SimpleStringScript Inherits SafeScriptingEngine Public Function CallStringScript(ByVal s As String) As String Public Function StringMethodExists() As Boolean ... End Class Again, all of this works great, just as desired and expected. The problem arises when you create a script that uses ByRef parameters. I would like a function that looks like: Public Sub MyCustomFunction(ByRef e as MyEventArgs) e.MyObject.MyProperty = "some value" End Sub I quickly discovered that any parameter being passed into another AppDomain must be Serializable, as do any objects that are referenced in its hierarchy. Otherwise, it will throw a SerializationException when you try to pass in the parameter. So, I changed all objects that are referenced in the EventArgs to be Serializable, and that solved the problem when calling. However, upon return to the calling AppDomain, the objects and values in "e" are still the same as before the call. None of the manipulations taking place in the script from the secondary AppDomain are carried back to the calling AppDomain. I figure this is because, as expected with the Serializable objects, the "e" is being serialized, sent across the AppDomain boundary, then deserialized. When it is deserialized, an entirely new object is created. Changes made are not sent back across the boundary simply by using ByRef arguments. Unfortunately, I'm not sure exactly how to solve this problem. I think I should be sending an Interface as my argument, rather than an object of MyEventArgs. As long as the Interface is well-known in both AppDomains, I think the scripting AppDomain should know what to call, and when it does, the call should be marshaled back to the primary AppDomain via the Interface. Basically, the Interface is just a pointer back to the actual object. Can anyone confirm this to be True or False? If False, please HELP! If True, then is it possible to simply wrap the MyEventArgs object into an Interface, such as "IMyEventArgs", then change the scripted function to accept the Interface rather than the object, then pass an Interface rather than an object into the method? Would that suffice, so long as both AppDomains are aware of the Interface and anything it references? Obviously, if the Interface referenced a type that is not loaded in the secondary AppDomain, then there would be problems because the script would not know how to use it. Or, do I have to wrap the EventArgs into an Interface, as well as wrap every object that it references into an Interface. Meaning, again using the example above, would I also need to create an "IMyObject" Interface? My workaround for the time being is to return the object being manipulated as the return value, that way, the new object (created from deserialization) is again serialized upon return. However, this requires the scripter to know that they need to return it. Using C#, that is no big deal because the compiler will tell you when there is nothing returned. However, in Visual Basic, if you fail to supply a return value, you simply get Nothing. But, since I will be writing the scripts, I'll deal with the workaround for now. But, I sure would like ByRef to work across AppDomains. Any suggestions?

    - HttpWebRequest ->HttpWebResponse question Hi... I ran into an odd circumstance using HttpWebRequest. Specifically, when you call GetResponse() it throws a WebException, to quote the msdn page, Abort was previously called. -or- The time-out period for the request expired. -or- An error occurred while processing the request. The last item is the part I find quizzical. "An error occurred while processing the request" appears to cover any non-200 return status while ignoring that, say, a 404 or a 500 status *can* have a payload that is of interest. A custom error page, or a 500-page might have information about what went wrong. Is there any way to get ahold of the payload when the return status is not 200? GetResponse errors out, and I can't find a property to stop that. Thanks -Mark Tag: Doing "&&" in codeDOM Tag: 93835

    - Word wrapping in Graphics.DrawString breaks words at umlauts Hi, I use Graphics.DrawString(string, Font, Brush, Rectangle, StringFormat) to render a string inside a rectangle with word wrapping. It works fine so far, but: If words contain german umlauts (ä, ö, ü etc.), lines are broken before or after these characters. The umlauts seem to be considered as delimiter characters. I can't find a language setting in the Graphics class or in the StringFormat class either. I tried to set stringFormat.SetDigitSubstitution(System.Globalization.CultureInfo.InstalledUICulture.LCID,StringDigitSubstitute.Traditional); but to no effect.

    - Line numbers of methods in dynamically generated assemblies Hello, I am dynamically compiling .cs files to In-Memory assemblies at runtime using CodeDom. This works fine. The resulting assembly is parsed via reflection to detect the implemented class and the the methods of that class. This works fine, too. Now, I want to match the detected methods to the responding lines of code of the original source file. This is the problem! Maybee I have overseen something, but after a hard day trying to understand and use the System.Diagnostics.SymbolStore namespace, I am completely stuck. The methods of the SymbolStore seem to be only partially implemented and they are quite poorly documented. Does anyone have an idea how to get the line numbers of the first and the last line of a method, from which I have the MethodInfo? Any idea is greatly appreciated! Thanks in advance Uli Tag: Doing "&&" in codeDOM Tag: 93820

    - Cost of using functions [vb.net] I was wondering if the use of functions decreases performance over placing all code after each other. For example: Instead of having function write anything to the screen using Response.Write(strMessage), I usually call a function DisplayMessage (strMessage), but now I'm wondering if this has any impact on the performance, or does the Framework recode (or how it is called) this to effecient code anyway. The main advantage is that, if I decide that those functions should not write anything to screen, I just have to disable that in only one place. Plus readability is increased :) Merely curious, as it is not really a performance issue, I'm wondering what the groups thoughts are about this. -- Message posted via http://www.dotnetmonster.com Tag: Doing "&&" in codeDOM Tag: 93817

    - Problem deploying C# application with ClickOnce Hi all, I've created a simple application in C# to test for ClickOnce deployment. After I've compiled the exe, I created the deployment manifest and the application manifest with "mageui.exe", and then put it onto a folder which could be recognized by IIS. I tried to click on the .application file in Windows Explorer, and the application is installed with no problem. Then I tried to do the same thing through a web browser, typing the URL directly. The update screen comes out normally, but after that an error message telling me that "Unable to continue. The application is improperly formatted. Please contact the vendor." is shown. The exception is attached at the end of this message. Since the XML files are created by mageui.exe without being modified, I think they should have no formatting problem. And I have already specified the Publisher. So is there anything that could cause this problem? (FYI I'm using English WinXP, and have my default language for non-Unicode programs set to Chinese (Taiwan)). Thank you.

    - Producer/Consumer example I am building an application where data is coming in from a hardware deveice attached to the serial port. The data needs to be queued ASAP. I figured a could create a custom class containing this data and store it in an ArrayList for future processing.
