Check For .Net Framework In 2005 App

May 28, 2009

I have distributed a simple VB 2005 application that generally runs just fine without any installation: the user just inserts the CD and it starts via autorun.inf. The rare problem the users have is if they do not have .Net Framework 2 installed. I want to catch this error in my application, and display an appropriate message. I also want to test this on my own computer (which of course has the Framework installed). So my questions are

1. Should I be using a try-catch-end try in the form load sub, or somewhere else? and

2. How can I test this on my own computer without un-installing the Framwork? If I can raise an error while debugging, what error number should I raise?

Check If .NET Framework Is Installed Before Running?

Jul 13, 2010

My application required .NET Framework 2.0.Currently, if it is not installed the user recieves the following error:The application failed to initialize properly (0xc0000135)'.It becomes extremely tiresome repeating to users that this is because the framework isn't installed. Is there some way to check if .NET framework 2.0 is installed before running, or in some way change this cryptic message so the user knows immediately

Enable  Application Framework Check Box?

Jul 30, 2011

The Enable Application Framework Check Box seems pretty well defined in a number oprevious postings, but leaves one question in my mind. The default is unchecked and the sub-topic Check boxes are:

Enable XP Visual Styles - - Checked

Make Single Instance Appllication - - Not Checked

Save My.Settings On Shutdown - -Checked

There are also 3 Combo Boxes:

Authentication Mode - - "Windows"

Shutdown Mode - - "When startup form closes"

Splash Screen - - (None)

When I un check the Enable Application Framework Check Box all items under it are grayed out. However, if I have changed one of the Comb Boxes my selection is also grayed out...My question is, have I lost the use of those function: Specifically I am mos interested in starting my application from a Sub Main and closing the application when all forms close.My underlying question is . . . are the greyed out selections still valid?

C# - Check If An Assembly Is A Framework Assembly?

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.

Alternatively, if that's not possible, how about checking the modules in an assembly?

VS 2005 - Create A "post Office" Program That Will Send Html Emails Thru The System.net.mail Framework

Oct 19, 2009

I am a one man dev shop and need some outside opinions on how to approach this project.

I need to create a "post office" program that will send html emails thru the system.net.mail framework.

For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.

The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.

The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?
