View 2 RepliesWrite Functions In Microsoft.NET (VB) To Avoid Memory Leaks?
May 8, 2012What is the best way to write functions in Microsoft.NET (VB) to avoid memory leaks. I have always followed this style:
Public Sub TestMemoryLeak()
Dim testCon As SqlConnection
Try
[code].....
Here the connection reference is created before the TRY clause and is initialised after the TRY clause. I believe the connection is always closed and dereferenced even if an exception is thrown. Is this good practice? I see a lot of code that creates references and dereferences in the TRY clause, but this would mean that the memory is not correctly handled if an exception is thrown. Some developers say they don't like to clean up in the finally clause.
Java, C#, VB: Write Thread Safety Functions Without Relying On Native Implementations?
Apr 24, 2011is it ever possible to write locking-features(for threading) with the language itself (this question is purely academic, I know no one will ever do it even if its possible (not me))?
A) In Java, is it possible to write thread safety functions with java alone, but without using any of the provided classes/language elements/syntax which offer this feature?
B) In C#, is it possible to write thread safety functions with C# alone, but without using any of the provided classes/language elements/syntax which offer this feature?
C) In Vb, is it possible to write thread safety functions with Vb alone, but without using any of the provided classes/language elements/syntax which offer this feature?

Creating A Link From The Control In One Form To The Entire Nother Form?
Apr 12, 2009I have another question (and anticipate that I will have about two more before I'm done with my class project). Here is my issue (and I'll copy and paste my code for clarification). I need to link up the control from the form on either side of the current form that I'm working on so that if I click on the buttons that I'm titling previous and next that I can click on the proper button and either go directly to the previous form or the next form. I was successful in doing this for two earlier forms on this project (with some direction from a couple of helpful people on this forum before), but for some reason, no matter what I details I use the controls do not connect to the previous and next forms.
Option Explicit On
Option Strict On
Option Infer Off

Use The Same Form For Several Functions?
Jul 20, 2009I am trying to use the same form for several functions which means I have to change the properties. In order to do this, I was trying to put a select case in a module that could be recalled anywhere in the project.
As soon as I start a select case in a module, I get an error message "Error1Statement cannot appear outside of a method body." Does that require that it be in a form only and cannot be used in a module?

Running VBA Functions In A Server Side Access Database From A WCF Service
Sep 23, 2011I've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop.I've ran the Open Current Database call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true.I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application.

Excel Maths Functions And Calls To All DLL Functions Documentation?
Jan 29, 20071) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?

Or for all those that Microsoft have chosen to document online at least.
Best Approach To Link App To Access Database?
Jun 3, 2011How to link my app to an Access database - there seems to be a number of approaches. I can add in my database via the Data Sources tab. Fine if I want to bind controls and view/edit data. But is this the best approach for queries that return an answer that is a different shape to the original table? Alternatively I can connect to the database directly (connection string, etc) and run sql queries. What are advantages/disadvantages of each approach? In terms of flexibility, is the second approach best? Also, does the second approach require the database to be added via the Data Sources tab?
