What I am basically wondering is how would I take a textbox on a form type some code in it and then run that code? Is this possible without 3rd party tools?
Is it possible to create and execute code at runtime?Eg, I make a string with this as the data: MessageBox.Show("Test")Then I 'run' the code from this string to produce a MessageBox
View 8 RepliesI have a windows form that imports data from an xls file to sql2005. I have a browser button, a dropdown list for the sheet names in excel and a process button. Now the excel file has 3 sheets (sheet1, sheet2, sheet3) the columns and data type are not the same so I need 3 different queries to access this file,
I think about CASE, but not very sure,
So if dropdown list.selectedvalue=sheet1 then

I'm using some VB.Net code to manipulate files on my system - the idea is that the code checks if a file exists, and based on a value read from a text file elsewhere the system decides what to do... For this I'm using a 'select... case' statement to decide on the action to take. However, when assigning a value to the variable, the code doesn't even find the option to go for... Here's the VB code:

I have a list with several fields that is created from dataset from a linqtosql query. At run-time, the user gets to specify what field he/she wants to display from the list. In other languages, I can dynamically do this like:
valueIwant=mylist(i).[fieldnameImInterestedIn]
Where 'fieldnameImInterstedIn is itself a variable. How do I do this in VB.Net?

Dim patientdata = (From patientvar In pdfdatacontext.tbPatients Where patientvar.PatientID = patientid)
Dim patientlist = patientdata.ToList()
fieldvalue=patientlist(0).(reportrow.userselectedfieldname)
I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}

I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.

I'm having trouble working out how to lock my application out of a section of code while it waits for a response from an external program've used Synclock on a section of code with the Me object in the expression. In this Synclock I call an overridden ShowDialog method of a dialog box, which has a timeout parameter, but does return the value from the underlying ShowDialog function call ,once the timer is setup. Works like this.

I am looking to create several custom controls (PictureBox Derivatives) on during runtime. I've read that the best way is to create template controls that will be created, and duplicate them in the Controls array.
Well, that's all fine and dandy, but what's the best way to store the template? I considered a seperate form with all the templates laid out on it for easy access for my editing, and keeping them out of the user's sight. I also considdered doing a Struct for each template, and smply mirroring values onto the control being created from the Struct to the created control.
I'm looking for ease of development first and foremost, as I'm most likely going to have a vast number of these templates, and keeping the system as simple as possible will eliminate a lot of hair-pulling. After development ease, I'd go for optimisation.
