CodeDom Reflections Slow Processing?
Jun 21, 2010
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.

A DataGridView in my VB.NET 2008 program contains over 15,000 rows. I loop through the rows, totalling groups of rows and appending 'total rows' and one 'Final total row' to the DataGridView. That works fine. I want to initially hide all rows except for the total rows, giving the user the option to show all 'detail' rows. If i place the statement << dgvTitleCounts.Rows(intRow).Visible = False >> in the loop, execution time increases by three minutes and that is unacceptable.
I see two options: (1) find a faster way of making all rows invisible; and (2) place the total rows in a separate DataSet and bound DataGridView.

I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

2008 Array Processing and Sequential File Processing
View 14 Replies
May 19, 2011
Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

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 )
Are there any tutorials for this?

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'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 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.

Ok how do I add a text file to a codedom executable?
I don't mean adding a resource file like this ".resources"
I mean adding a textfile to the already existing resources.

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

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)
