    - A RegEx question Hi, Can some kind RegEx guru give me some help? I want to parse an expression of the form: EXECUTE func [param [,param...]] In other words, the expression begins with "PARAM" followed by whitespace and func, optionally followed by whitespace and one or more comma-delimited parameters (where the first parameter is not preceded by a comma). My question is, how do I construct a RegEx expression and evaluate it so that I can iterate through the zero or more "param" strings contained in the expression? Thanks! - Bob Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69605

    - file not being released in a timely manner I've written a vb.net webform based application. It uses CDO and it runs through a list of database records and for each record, it creates a new email object, attaches a single file, and then sends the message. I use message.AddAttachment(AttachedFile) to attach the file. After I've sent the message I copy the the file that was attached to the message to a backup directory. I then delete the file. The copy is instantaneous. However, it can take quite some time before the file is actually deleted. It varies between a couple of seconds and more then a few minutes. If I close the application, the file disappears within a few seconds. I believe that the email object is holding onto the file until Garbage Collection completely reclaims the email object. I've added GC.Collect right after the email is sent and after I've set the email to nothing. It speeds up the deletion but not in a predictable manner. What's the best approach to speeding up the reclamation of the email object so that it releases the hold on the file? Do I have to take into account that the email object is created using CDO? Is the CDO library considered unmanaged and if it is does that complicate the disposal of the email object? Thank You, Eric Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69599

    - ANN: Galois.Net Hi, I have posted recently a similar message, I believe it is particularly interesting for people with a mathematical background. Also, the whole application was developed with .Net Framework SDK only. The beta version of Galois.Net is now available for download. Galois.Net is made of two parts: the Galois Knowledge Environment and a collection of Xml tags. The Environment is used to create and share theories presented using the Xml tags. You can download it at: http://www.a2ii.com/galois/index.htm More information about Galois.Net can be found below. Daniel Perron, Ph.D. Lead Developer Galois.Net ========================================================= XML specifications for .Net components The Visual C# compiler has an option switch that extracts the comments within the source code of the program being written if the comments follow a certain XML syntax. This simplifies the generation of reference documentation for the application. Java compilers also have such a facility and we can probably trace the original idea behind such a feature to the proposal for Literate Programming made by Donald Knuth in the 80's. In this note, we would like to extend these ideas using custom attributes provided by the .Net Framework. We'll start by defining a custom attribute named Galois as follows: using System; namespace Galois { [AttributeUsage( AttributeTargets.All, AllowMultiple = true )] public class GaloisAttribute : Attribute { string theory; public string Theory { get { return theory; } set { theory = value; } } public GaloisAttribute( string thm ) { theory = thm; } } } We have created a namespace for this attribute and the attribute itself has only one read-write property Theory of type System.String. You can compile this code and reference it in your application. The Theory property of every Galois attributes will be an XML string with tags chosen to allow specifications in a certain logic, namely geometric logic. Geometry logic has nice mathematical properties (the class of models of a given theory constitutes what mathematicians call a topos). For example, we would like to attach a Galois attribute to an interface that will be used in every Windows.Forms program that use a menu as follow: using Galois; public interface GTMenu { [Galois(@" <co a1='p' t1='Program' a2='m' t2='Menu' a3='s0' t3='Statement' a4='s1' t4='Statement' a5='s2' t5='Statement' > <if><pr n='Uses' a1='p' a2='m'/> </if> <tn><te a1='a' t1='Array'><pr n='ElementType' a1='a' a2='Statement'/></te> <pr n='GetValue' a1='a' a2='0' a3='s0'/> <pr n='Equals' a1='s0' a2='MainMenu.ctor'/> <pr n='GetValue' a1='a' a2='1' a3='s1'/> <pr n='Equals' a1='s1' a2='MenuItem.ctor'/> <pr n='GetValue' a1='a' a2='2' a3='s2'/> <pr n='Equals' a1='s2' a2='AddEventHandlerForClick'/> </tn> </co> ")] void SetupMenu(); } Let's look at the interface itself first. The interface is named GTMenu (for the Galois Theory of Menu) and it contains only one method SetupMenu() (note also, the "using" statement at the beginning to be allowed to use Galois custom attributes). The Galois attribute itself is attached to the method SetupMenu of the interface. The string that is passed to the attribute starts with the @ sign so we can break the specifications on multiple lines and we use ' (a single quote) inside the string to delimitate the XML attributes of the Galois.Net elements that we are now going to describe. The top-level element of the XML string is <co a1 ...>. The "co" element of a Galois attribute defines a context which is a list of variables names and theirs types (as in a1='p' t1='Program' for the variable p of type Program). Inside this context element, we have an "if" element for the "if" part of a rule and "tn" element for the "then" part of a rule. Galois.Net specifications are made up of contexts that define the variables used in the rules. Inside the "if" element or the "tn" element we can have relations (or predicates). In the specification above, we have inside the "if" element, the relation Uses which is written as the element "<pr n='Uses' a1='p' a2='m'/>" which says that "if the program uses a menu then ...". Then what? The specification says that there exists an array of statements whose first member is a MainMenu constructor, second member is a MenuItem constructor and the third member is the statement 'AddEventHandlerForClick'. The "te" element states that "there exists" a variable of type Array. The specification also uses the predicates "GetValue" which is true if the value of the object at position, say 0, is s0. Galois.Net specifications treat a function as a relation that defines its graph. And if the function is a method then its first argument will be the name of the given object (just like when the pointer "this" is passed to a function in a given implementation of a compiler for an object-oriented programming language). This specification can be displayed (in the Galois Knowledge Environment) as follow: Context: For All p: Program, m: Menu, s0: Statement, s1: Statement, s2: Statement, IF (rule #1) Uses( p, m ) THEN THERE EXISTS a: Array ElementType( a, Statement ) GetValue( a, 0, s0 ) Equals( s0, MainMenu.ctor ) GetValue( a, 1, s1 ) Equals( s1, MenuItem.ctor ) GetValue( a, 2, s2 ) Equals( s2, AddEventHandlerForClick ) We can conclude that this context defines a language with: 4 sorts (Program, Menu, Statement, Array) 3 predicates (Uses,ElementType, GetValue) where Uses < Program x Menu (we use < for the subset relation) ElementType < Array x string GetValue < Array x int x Statement the constants 0, 1, 2, MainMenu.ctor, MenuItem.ctor, AddEvenHandlerForClick, and a geometric theory with a single axiom. Any interpretation (or model) of this geometric theory will involve assigning "universes" for the different sorts. Usually these universes are just plain sets, but generally, they can be taken to be objects in any given topos. Then the predicates will be subsets of the appropriate product of sorts and the constants are elements of the sets that represent the given sorts. The values for the statements in the above specification i.e. MainMenu.ctor, ... were chosen to reflect the knowledge that would be needed to implement a menu in a Windows.Forms application. A program that implements the GTMenu interface with its Galois attribute could be written as (when compiling, remember to add a reference to GTMenu.dll compiled earlier): using System; using System.Drawing; using System.Windows.Forms; class CreativeGL : Form, GTMenu { public void SetupMenu() { Menu = new MainMenu(); MenuItem menu = new MenuItem( "A menu" ); Menu.MenuItems.Add( menu ); MenuItem miOne = new MenuItem( "One Item" ); menu.MenuItems.Add( miOne ); miOne.Click += new EventHandler( miOneHandler ); } public CreativeGL() { SetupMenu(); } public void miOneHandler( object o, EventArgs ea ) { MessageBox.Show( "You clicked the menu item" ); } public static void Main() { Application.Run( new CreativeGL() ); } } This is just a test program but it shows an important idea: A program can be seen as a model for the theory specified in the Galois attribute (of the interface that is implemented by the program). A more detailed specification makes it easier to associate values to symbols in the specification i.e. to define a model. Because the tags of the Galois attributes were chosen to express specifications in geometric logic these remarks can be made formal. As a simple consequence of this formal theory, a "bug" has a nice interpretation in this setting: since a rule in a Galois specification essentially represents the claim that an abstract geometric object is contained in another one, a bug is a point of the smaller object which is not covered by the "bigger" one. Creating components with Galois attributes wouldn't be very interesting if we were not going to exploit this extra information contained in the specification. Luckily, the .Net Framework makes it very easy to extract custom attributes from components. The Galois attribute used above was written to express the minimum information needed to create a Windows.Forms with a menu (we could make it more precise to include the information that we need to add the menu item to its container). Similarly, the same approach could be used to express the minimum information needed to created a client network application, a server network applicaton etc... And more generally, we can use Galois specifications to make explicit the information that programmers assumed when they are writing their code. This way, we could extract all the theories contained in all the code written by a given programmer and treat this as a representation of his/her expertise. Going one step further, we can imagine a programmer displaying this representation in the form of a Web service that is used to "contract out" this expertise. We believe that custom attributes, as used with Galois.Net to specify components, fill an important gap in providing a nice semantic for component-based software development.

    - Assemblies for custom component not loading Hi all, I've got a solution containing several projects for some components I'm trying to develop: A, B, C A inherits from System.ComponentModel.Component. Its purpose is to house some base functionality for my suite. B inherits directly from A and does it own thing. Likewise C is a more specialized component of type B, so it's inheriting straight from B. Compilation goes fine and all three resultant dll's are in C's bin\debug folder. So we have A.dll, B.dll and C.dll all in the same folder. I then added a registry key for the AssemblyFolders key with this output as the default value for the key. Reopen vs.net and my components (all called Class1), are showing up in the ".Net Components" box when you click the Add/Remove context menu. I put C on the toolbox.. drag and drop it on the form and nothing is placed on the component tray. I used fuslogvw to log assembly binding and got entries for A and B: *** Assembly Binder Log Entry (2/19/2004 @ 4:03:27 PM) *** The operation failed. Bind result: hr = 0x80070002.

    - WSDL generates array rather than data type In generating a proxy using WSDL, a collection type I have defined is transformed into a simple array. This later causes data to not be passed correctly in the web service client. Here's a partial example: <xs:complexType name="MyResponse"> <xs:sequence> <xs:element name="MyList" type="MyList" minOccurs="0"/> <xs:element name="OtherData" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="MyList"> <xs:sequence> <xs:element name="MyListDetail" type="MyListDetail" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="MyListDetail"> <xs:sequence> <xs:element name="DetailId" type="xs:string" minOccurs="0"/> <xs:element name="DetailDescription" type="xs:string" minOccurs="0"/> </xs:sequence> </xs:complexType> The pertinent generated C# code looks like: [System.Xml.Serialization.XmlTypeAttribute(Namespace="xxxxx")] public class MyResponse { /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public MyListDetail[] MyList; Note that the generated .cs code types MyList as simply an array of MyListDetail objects rather than typing it as a MyList object. This seems to cause a problem where the data put into the MyListDetail objects do not appear on the client side after calling the web service. If a "dummy" element is added to the MyList definition, the actual MyList data type is generated, and the data passed in the MyListDetail objects are passed back to the client as expected: <xs:complexType name="MyList"> <xs:sequence> <xs:element name="dummy" type="xs:string" minOccurs="0"/> <xs:element name="MyListDetail" type="MyListDetail" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> [System.Xml.Serialization.XmlTypeAttribute(Namespace="xxxxx")] public class MyResponse { ... /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public MyList MyList; ...

    - Publish WMI instances from W32 service consumes memory without stop Hello to all, I'm developing a Win32 .Net service that publishes information into WMI by using Publish method, however once an instance is published, memory usage starts to grow without stop at a rate of 1Kb/sec. This problem only appears when publishing information through a service. Also I noticed that problem only appears on some machines (most of them) since a couple of my machines does not present the problem. Is there a way to solve this problem?

    - Help: Placing Internet Shortcut for Windows Forms application (hosted on web server) on Desktop Hi there, I have a Windows forms app that resides on a web server. I (and my intended user base) access the application via an Internet shortcut, i.e. "http://servername/appshare/app.exe". That's all fine and dandy, as well as the setup and deployment project I had to write to install/uninstall a Site code group to give FullTrust to any applications from "servername", but that's another story (code's available if anyone's interested). So, one last thing I wish to do: During the install, create an Internet Shortcut on the desktop which points at "http://servername/appshare/app.exe". As far as I can see, there's no way to create an *internet* shortcut during the install process or via code - does anyone have any suggestions?

I selected "Make Changes for this User Only", navigated to the .DLL, said to trust this assembly only, and got this error: "Due to your existing security policy, the wizard is unabel to increase the level of trust for this assembly. No changes were made to your policy." How can I make my user account trust my assembly? Thanks. Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69531

    - Should I drop Library activated Serviced Component from COM+ when the interface changes? I would like to understand better what happens when a public interface of a serviced component changes Suppose that I have a library activated serviced component. Suppose that I lock its version number ([assembly: AssemblyVersion("1.0.0")]) and installed the component into COM+ catalog (via regsvcs or just by running a client that uses it) Now, suppose that I change the existing method or add a new method in the component It appears that everything continues to run fine afer the change I am not sure, though, if this is the way to do it. I always drop the component from COM+ catalog when the interface changes Question is, do I need to? Is it really necessary What exactly is going on with component when the interface changes Thanks -Sta Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69528

    - "Assert failed" under Windows 98 Hi, I've developped a Window Form application with .NET that runs perfectly well under Windows 2000, XP and 2003. However, when i run it under Windows 98SE, i get the following error *after* the application has been closed (MyApp is the name of my executable): "Assert failed - copied to MyApp.err" File Refcount.cpp, line 652 Build: v7.10 (07/08/02 11:27:29) Expression: ! (i == idata->tdmap.end()) The strange thing is that it doesn't happens when my code is executing but sometime after the execution is finished, probably somewhere in the framework itself when it's cleaning up after a program has been closed. If somebody has a clue of what's happening here, please help! i have no idea where to look as the error comes from outside my code:-( And this just prevents me from distributing my application to Windows 98 users which was one of my targeted platform.

    - Cannot access properties on Custom classes After upgrading to the 1.1 framework, we can no longer access properties or methods on custom classes. The same classes in the 1.0 framework could be viewed just fine using the Quick Watch or Immediate window. The only thing that can be seen on the classes are the Public Constants (strings) In the immediate window, when trying to view the value of properties the following exceptions occu ?object.PropertyGUID.ToStrin Run-time exception thrown : System.ArgumentException - Cannot find the method on the object instance ?object.PropertyStrin <error: an exception of type: {System.ArgumentException} occurred Using QuickWatch, the Value column of the view shows the properties as <error: an exception of type: {System.ArgumentException} occurred>.

    - CCW overheads To whom it may concern: We are in the process of deciding on a technology to go with - .NET or VB6. The project entails interfacing with Classic COM objects written in C++ on another system. I've suggested that we write our custom code using the .NET framework and expose it to the classic COM objects using COM Callable Wrapper. Others suggest that we should go with VB6 (Classic COM to COM communications)so as to circumvent any form of overhead that could be incurred during the CCWs "wrapping" process. Any form of feedback is much appreciated. Best, Jack Sparrow Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69508

    - XmlSerializer / Temp directory / System shutdown My application has a settings class that is serialized to save and deserialized to load. I'm having a problem where i catch the WM_QUERYENDSESSION event via WinProc to save my application's settings when a user logs out, reboots or shuts down the system. The behavior of XmlSerializer is that it creates temporary dll's to do the (de)serialization in the system's temp directory. The behavior of windows on a system shutdown is to purge these temporary files from the system's temp directory. The problem i'm having is that i am unable to serialize my settings class when the system is shutting down, because windows is purging these temporary files. Is there a way to control the directory where the XmlSerializer creates the temporary files (other than changing the TEMP environmental variable, which isn't an option for me), or is there another means of serialization i can use which bypasses the temporary file creation step? My settings class has hundreds (potentially thousands) of things getting saved to a file. Manually serializing/deserializing would be a real pain that i am hoping i can avoid. This seems to be a big flaw in the .net xmlserialization implementation. :( Tag: HOWTO: Convert a string in scientific format to a decimal Tag: 69507

    - AssemblyVersion - what if I want to enter DLL Hell? The title is a joke, clearly I don't want DLL Hell. However, I am curious if there is a way to follow the shared DLL model of the past using the GAC. Specificially - I have ten seperate console applications, lets call them 'ConsoleApp1.exe' through 'ConsoleApp10.exe' which each depend on a single class library named 'Utility.dll' which is strongly named and installed in the GAC, v1.0.0.1 I regularly develop performance improvments to 'Utility.dll' which I want all the console apps to benefit from. Over time, i develop v1.0.0.2 , v1.0.0.3 all the way to v1.0.0.9 - each time I wish to deploy the updated library and have all of the console apps use it. Is there any way for me to install the new class library in the GAC and have it used by all console apps WITHOUT using a Publisher Policy File (i.e., is there any way to mark the new library as "compatible" and therefor the console apps will use the newer version).

    - Components added to a Components Surface not in Components Collection? I've created a Component called MyComponent. To the design surface of MyComponent I've dragged an SqlConnection object, an SqlCommand object, and an SqlDataAdapter object and linked these items together appropriately. My question is this: Why are these Sql components not added to the list of components contained by MyComponent? (These objects are not added to the private "components" member of MyComponent.) Is there a technical reason for this or is it just a bug in the designer? Is there any way I can get the Designer to add these items to the collection automatically, without having to hand-code it myself?

The problem raises when i try unistall the class library from the Assembly Cache, the error says that the library has a reference with an instaler program. I've removed it from the solution and the problem persist... Is there any other thing that I'am not doing..? I would really appreciate your helping me....!

Hi,

How to convert "1283912839E-5" string (in scientific format) to a decimal.

Convert.ToDecimal("1283912839E-5") is throwing "Input string is not in
correct format" exception. Is the exponential format not supported during
conversion?

I think we need to use NumberFormatInfo, but dont know how to use the format
specifiers in the NumberFormatInfo.

Thanks in advance.
