I'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 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'm dealing with a variable of the type string, in a "select case" code; if the string in it was "5a6-Hor" then some calculatins will be made. the problem is that the value would be "5a6", but the case related wont be applied(the compiler isnt reding it as "5a6"), although i had a msgbox showing the value of the string as "5a6", as was defined under form_load event here is the code:
with the code i made till now found below i'm putting a word in txtEnterMsg and this goes into position 5 of the letters i have in txtLetters. How can i put each letter of the word i write in txtEnterMsg in a different index.eg--if word is 'hello' put 'h' at index 5,'e' at index 13.
I am looping through the rows of a DataRowCollection and assigning the fields of each row to a variable. I always get "Input string was not in a correct format" no matter how I cast this. I just need gapCd to contain 0 if the field is null or the value otherwise. It seems the IsDbNull is not returning true properly. I've also tried DbNull.Value comparisons with no l
Are there any alternatives to Codedom? THe reason I am asking is because Codedom is not letting me use pointers(unsafe code) which is a must in my project. I have hear of the System.emit namespace though.
Okay 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 )
Does microsoft have documentation on how to use VBCodeProvider and codedom or any .net book that provide detail on how to use it. i tried to use it to compile program on the fly but never work. It always gives me an errors such as path to the string or file not found.
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?
[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.
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
today I attempted to create a simple application using codedom.Basically I want to be able to compile a messagebox with the custom text entered in the builder.
This is what I have so far.
ICompiler.vb Class "Codedom" Class and in my main form "the builder I have this
[Code]...
If no one could help me perhaps does anyone have a simple source example?
there is an example from MSDN: 1 solution - 2 projects: service and client like this: service:
<ServiceContract()> _ Public Interface ICalculator <OperationContract()> _ Function Openserv(ByVal n1 As Integer) As Boolean
[code]....
but the client make an exception "timeout expired"... how can I make it work? maybe use something else instead netpipebinding? I can rewrite this on C#, if it will help. how to call from generated assembly another sub of generates it class?
How do you pass a control (say a textbox) to a function as a parameter in compiled assembly using CodeDom? I've tried passing through the args in the Invoke method but it doesn't work.[code]...
In my main application i am trying to run Pre-defined Code blocks that the user has created. I would also like to send a DataSet as a parameter when the code is compiled. Is this possible. Currently I can pass in single values by assigning them as a string in the code wrapper through the <%= input %> expression. Then i compile this as source.
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
Dim para As New CodeDom.Compiler.CompilerParameters Dim Ressources As New List(Of String) Ressources.Add(Application.StartupPath + "data.dat") Dim temp As String = Path.Combine(Path.GetTempPath, Path.GetTempFileName) If Ressources.Count > 0 Then
How can you write a VB.NET Windows Forms Application via CodeDom? I have tried everything, the closest i got to it is the code below, which first of all shows command prompt window which is not good, and then shows the form for like a second and everything disappears.
I'm fairly new to learning visual basic. I'm trying to create a program that dynamically generates a EXE file that performs mouse movements and keystrokes. To dynamically generate EXE files, I am using the CODEDOM API for Visual Basic.
I know that I can launch activate/Use functions in assemblies that I have created, but can I start subs? and If so could I start Sub Main from an Assemble? What I mean is I want to run the created program in memory from a sub main and I dont know how .
My other question is how can I change the type of output project? So from a console app to a Windows Form app? ( I am no longer talking about using the assembly dynamicly this is more about creating the physical exe as what I want it as.
I know that they are the Compiler options command line but is it the same as the ones that Visual studio use when compiling? (The ones you see in the out put window)
I'd like to know how to pass a DataSet to use in compiling code with the CodeDOM. I know how to pass single values as string but not a Dataset. I replace the <%= input %> with my logic statement provided by the user and then compile code. But how to send a loaded Dataset along with it I cannot figure out.
Dim code = <code Imports System Imports System.Windows.Forms[code]....
Is there a way to remove items in code generated in Codedom from VB code?
For example at the top of all the code I generate, it has:
[Code]...
I'd like both of these to go away - the commented text and the both the Option xxx. I've tried toying around with CodeGeneratorOptions, but have not been able to remove the above from generated code.
