I have this function in my generator.[code]Despite the data type being passed into the constructor of the CodePrimitiveExpression object being a decimal, the code generated is an integer that gets implicitly converted and stored in a decimal variable. Is there any way to get it to generate with the "D" after the number as in: Public Const DollarAmountMaximumValue As Decimal = 100000D

Is there a way to create a delegate instance in .Net using CodeDom? I want to generate something which looks like the following:Dim myDelegate As someDelegateType = New someDelegateType(AddressOf implementingMethod)Below is more info on the context...Original Question:I am using CodeDom from the .Net framework (v3.5 if it matters) to generate a class. One of the classes defines a delegate method which in VB.Net looks like:Public Delegate Function filterByIdDelegate(ByVal obj As Object, ByVal id As Integer) As BooleanI then have a method which will provide the implementation:Private Function filterById(ByVal obj As Object, ByVal id As Integer) As Boolean Return (obj.ID = id)nd FunctionHere's the problem; how do you create an instance of the delegate (using the equivalent of AddressOf for VB.Net)? I am currently doing this (<filterByIdFunctionName> is a string holding the name of the delegate function, `' is the name of the delegate field):
Dim getFunction = New System.CodeDom.CodeMemberMethod()
With getFunction
'Declare delegate instance

I am trying to create a procedure which will evaluate a string expression as if it were a line of code...Kind of like what a graphing calculator does when you enter a formula. Does anyone have any experience with this in VB? I have an example of C++ code which uses CodeDom, but I am a bit rusty with my C++!

I want to create an array of constant variables for my program. But from everything I read about arrays they are handled by a number. I want to be able to pass back a variable that will hold the name of the constant as well as the value. How would you go about do that.I want to when I type the variable to have the constant name show up as I am typing.
View 4 RepliesWhen building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.
What is the cleanest, most readable way to String.Format a decimal with the following criteria
start with a sign symbol (+ or -)
a fixed number of fraction digits
no decimal separator
right aligned
pre-padded with "0"'s

View 2 RepliesOkay Is there a way In vb.net to create an exe from a predefined script, for example rather than writting the methods and subs into the codedom code could I just have a textbox that I could put a script into and then have that built? (obviously omitting button presses and things.)
Im not worrying about ui's at the moment just and exe (hello world style )
Are there any tutorials for this?

My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .
View 2 RepliesHow would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01
View 5 RepliesI'm trying to see if Codedom can handle strings and concantination between different languages, without me setting up conditional strings per language.For example, I need to generate the following exactly as shown below in both C# and VB.NET via Codedom:
C#
errorMsg = errorMsg.Replace('"', ''').Replace("
", @"
");
System.Windows.Browser.HtmlPage.Window.Eval("throw new Error("Unhandled Error in Silverlight Application " + errorMsg + "");");
[code]....
The CodeMethodInvokeExpression for errorMsg.Replace and System.Windows.Browser.HtmlPage.Window.Eval is simple enough, it's the string inside them that I can't figure out if Codedom can automatically handle.
I'm trying to make an application, Where users can insert code, and it will compile a form for me. so like the user inserts

I essentially took this and played around with it url...If i build a codedom like the msdn link shows i can generate cs and vb code. However if i read cs or vb code back and try to generate the source in the other language i just get whatever code i originally read from (you'll see cs code in the vb file and vice versa).How do i read in source from one language and generate it to another?
View 1 Replies[code]I already had to add in bits to the example code to actually name the property to match their example output, I suspect that there is a detail missing that is causing this, but I can't seem to track it down? Whilst the code compiles, I'm unable to use the properties without manually adding in the parameters, which defeats the purpose somewhat.

I don't mean adding a resource file like this ".resources"

The following is a program that lets users store business logic for later retrieval by other users.
I am trying to run multiple logical statements pulled from sql server database. one statement may be dependent on another one. I've been compliling the code in a wrapper and In-Memory set to True. I ran 18 logical statements in a loop and it took approx 3 seconds to run. These were simple one line statements containging math and/or If Then's.
Any other methods available out there. please no 3rd party plug-ins.
Is there a way to use CodeDom to generate an overloaded operator in Vb.net? I want to generate this:
Public Shared Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return x Is y
End Operator
The closest hack I can think of to do this the following:
Dim eq As New CodeMemberMethod()
eq.Name = "Operator ="
eq.Parameters.Add(New CodeParameterDeclarationExpression(New CodeTypeReference("MyType"), "x"))[code]....
Which generates this, close but obviously wrong:
Public Shared Function Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return (x Is y)
End Function
