Jun 27, 2012I have created a simply Pizza program (for a summer project not education related) that uses check boxes to determine what the customer wants. Basically a simple pizza ordering program.I was wondering as I have used the If statement over and other again for different parameters and variables, is it possible to use multiply arrays to simply the VB Code...I was advised to use Constructors in VB.Net Or is there a more simpler way to go about creating this program...or a better way of programing?What about decreasing the repetition in the code?

View 1 RepliesForms :: Optimize Code And Lower CPU Usage?
May 14, 2009When my form first loads, it runs at about 30k CPU, but after about 10 minutes of use, it goes up to (and stays at) about 70k CPU.
What ways can i optimize my code to allow the CPU usage to stay low, or how can i lower it during the running of the program.
My most concerned areas of the CPU are:
1. I have a web browser, and when a user types in a url and presses go or enter, the CPU jumps about 4k:
Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
WebBrowser1.Navigate(OldURL.Text)
[Code]....
The second worry is when i open other forms, it boosts the CPU up aswell. the only code for this is:
Form.Show()
Optimize The Code For Copying Data From One Dataset To Another?
Oct 6, 2009this is in reference to my main post here update mdb with data from different tables in dataseti have two tables in a dataset called dsSource. dsSource.Tables(0) has the following columns: ,,,,,,,code,art,sizerng1,sizerng2,sizerng3,etc...... dsSource.Tables(1) has the following columns: ,,,,,,,code,art,size1,size2,size3,etc...... the conditions here are: 1) to look for "1" in columns sizerng1, sizerng2, etc. of dsSource.Tables(0) 2) match code and art on both tables finally if both conditions are valid then the size values in columns size1, size2, etc. will be assigned to columns in sizerng1, sizerng2, etc. my main concern here is i have to loop through all rows in both tables which takes a long time, so is there a better way to do this than the code i have below?.

Asp.net - Simplify Email Body In String?
Oct 20, 2009I'm just wondering about this one. I'm creating an ASP.NET webform containing lots of textboxes etc. And I want to send an e-mail based on this stuff. And the e-mails body needs to go into a string. And the string is supposed to contain HTML code, but the syntax changes because of the string. So how can I simplify this? Is there any software or something that lets me do this? Perhaps paste in some HTML code and then convert this to string format, ready to use with vb.net?
View 2 RepliesSimplify A Weekly List Of Events For A Web Site
Aug 17, 2009I am writing a program to help simplify a weekly list of events for a web site without having to manually edit HTML code every single week.
The program takes event information from the user, stores it in a list box, and generates HTML code based on the user entry. The program basically enters in the user's inputted fields into a pre-set HTML template.
Here's how it's done:
1) I have a number of text boxes that the user fills out: "Date" "Event Title" "Age" "Location" "Details" etc.
2) The user clicks on the "ADD" button to store this event. The "Event Title" is shown in the list box, but I'd like for all of the information that was taken from the user before they clicked on "ADD" to be recalled in another text box.
3) The user can move events up or down in the list box, or remove them completely.
4) When the events have been sorted, the user hits the "GENERATE CODE" button and the html code is generated.
So lets say the list looks like:
- DJ Jim at Katrina Lounge
- DJ Heather at Zanzibar
- DJ Manny at Skybar
When the user clicks on the "DJ Jim" event, the full details that they entered earlier will be shown in a text box to the right of the list box. When they click on the "DJ Heather" event, the text box will reflect the details they entered for the "DJ Heather" event, and so on.
When the user click on "Generate", the program must be able to go through each item in the list box, recall the event details for that item, and plug in the variables for that item into the HTML code template.
The main question is, how can I store the information for each event (Event Title, Date, Location, etct.) while displaying only the Event Title for that even in the list box? If I know how to code this, it will be simple to display this information in the text box and recall the variables to plug into the HTML code
So the structure would be:

Socket Programming And Telnet Class For .NET To Simplify The Sending And Receiving Of Data?

Will The Compiler Optimize This
Mar 8, 2012Consider this
bar = 1
foo = <1 or 2, depending on previous code>
if foo=1
while bar <= 5
[code].....
What I want to know is, is the compiler smart enough to optimize away the (apparently) repeated tests for "foo = 1" since foo is not modified in the body of the loop?If so, I might use the second construct since it is semantically equivalent (I think!), takes less code and reduces indentation levels.

What Are Things Vbc.exe Does When /optimize Switch Is Used
Mar 6, 2012vbc.exe has something called /optimize switch right. If I enable that what are the optimizations the compiler can do for me? The MSDN documentation just curtly says 'does various compiler optimizations'. Where can I find the complete quantified view of the different optimizations that actually goes into.Here is the thing I am pursuing this route. One of the code blocks in a module I am leading has a lot of delimited array manipulations. I believe this is going to be a heck costly in terms of string memory handling. I am looking to see if I can retire them by way of simple properties or methods so that the compiler can internally do something like our c++ inline functions making a best win-win offer in terms of both memory and processing time. I admit when the compiler translates them as inline function, the JITed code might be big in size right?

View 2 RepliesOptimize Classes Before Serializing And Saving
Oct 24, 2010Often it is very usefull to save data as a class by serialize and compress it. From few experiments I have noticed that
Class A
Public name as string
Public List as new list(of string) <---- empty
End Class
Class B
Public name as string
Public List as list(of string) <----- not instantiated
End Class
If I serialize and compress the 2 classes the class B uses less spaces once serialized and compressed. This suggests me that if a class contains a list that is instantiated but empty it is better to set that to nothing and reset as new when it is decompressed and deserialized. Is there any dll that optimizes a class to be stored (serialized and compressed) and restore it when it is decompressed and deserialized?

C# - Does The JIT Compiler Optimize (inline) Unnecessary Variable Declarations
Oct 20, 2011I've read several articles and questions/answers that conclude the best practice is to let the JIT compiler do all the optimization for inline function calls. Makes sense. What about inline variable declarations? Does the compiler optimize these as well?

Of course I prefer the latter because it's easier to read and debug, but I can't afford the performance degradation if it exists. I have already identified this code as a bottleneck -- No need for retorts about premature optimization.
DB/Reporting :: Optimize Query (aggregates On Multiple Tables)?
Feb 20, 2008Code:
Tables:
- Company
- Department
- Employee
- CertificationA
- CertificationB
I am trying to return a recordset that gives some summary information about each company. The fields in my returned recordset should look like the following.
Company.Name, NumberOfDepartments, NumberOfEmployees, NumberOfCertificationA, NumberOfCertificationACompleted, NumberOfCertificationB, NumberOfCertificationBCompleted
There are actually about 10 different Certification tables but, with Certification A and B you should get the hang of it. When an employee starts a certifaction, a record is added to the that certification table.Below is a query I wrote that works (gets me the data I need), but I am unsure if it is the most efficient way. There will be quite a lot of data so performance is an issue.

sqlNumberOfDepartments = _
