Basic Mastermind Game - Don't Want Any Colors To Repeat - Values Still Repeat Sometimes
Feb 17, 2011I'm trying to make a mastermind game program with visual basic. I started of creating the combination maker for the start of the game. Hoever, in my version i don't want any colors to repeat. I used the random function independently to get numbers from 1 to 6. Each number has a corresponding color. The problem, the values still repeat sometimes.
Here's my code for that part:
Randomize
a = Fix(Rnd * 6) + 1
txtA = a
If a = 1 Then

View 11 RepliesGraphics.Drawstring Ignores Kerning Instructions?
Dec 14, 2011I was unhappy with the kerning in one of the installed fonts on my system, so I re-defined the kerning in a font editor and installed the revised font (under a new name) on my system. When I use the new font in Microsoft Word or Adobe Photoshop, my new kerning works fine - but when I use Drawstring in a VB program, although the new font is used, the kerning instructions are ignored.Does anyone know if this a feature of the Graphics.Drawstring method, or am I failing to set a switch somewhere? If it's a feature, is there another method which kerns correctly?

Feature In VS2010 - Set Of Instructions And Save It As A Macro (ex: MYMACRO)
Dec 1, 2011There is a feature I used to have in zOS assembler environment that I'd like to know if it's available in VS2010 (VB .net). In assembler it is called macro language :
First, I define a set of instructions and save it as a macro (ex: MYMACRO)
Second, anywhere in my source code I can call the macro (by adding the line "MYMACRO")
Third, when i launch the compilation/link step, the compiler implicitly replaces all the "MYMACRO" lines in the source code by the content of MYMACRO defined in first step.
Is there a feature like this in VS2010 ?
Example:
Content of macro CONTEXTSTART with a parameter &id
Try
ContextManager.Start(&id)

Fastest Way Of Searching For Row In A Dataset?
Dec 5, 2011I have a program that scrap websites and "puts" the information into a table.
My problem is that now and then i get values that i already have in the table. to avoid getting duplicates i search thru the table first to see if the value exist or if the record exist but might be in need of getting updated.
My table contains 60 000 records and is growing.
first i filtered a datagrid but it takes to long so i used the "select" method on the dataset table but it takes longer.
the program loops thru thousands of websites so it'll be doing a search for every website and the added time to collect the data just takes too long.

Performance - Fastest Casting In .NET?
May 14, 2009When I have many controls on a Form (i.e. Label, Button etc) that do almost the same thing, I often use one method to handle all the controls Click, MouseDown, MouseUp events.But to know which of the controls throwing the event and access the properties of that control I need to cast the "sender" object to the correct type.
The thing is that I always know which type it is, I don't really have to "TryCast", "DirectCast" and check if the operation returns true. I some times use CType as well.

Apr 19, 2012I have a pixel I want to monitor for change. For example, first it is white, and suddenly it is black, and then changes back to white. My method is not fast enough to get this change.any changes I call the function below to get the original color of the pixel. Then I have a timer that runs every 1 ms to take the color of the pixel, and if it's not equal to original color; do something. For example counts the time the pixel has changed. However, this function does not run fast enough. Is there any faster methods to check the pixel? The function returns an ARGB code of the pixel color.[code]....
View 3 RepliesFastest Way To Generate Thumbnails - Without Bogging Down The UI
Apr 29, 2012The fastest way to generate thumbnails using VB.net and multiple computers without bogging down the UI. Right now I have 3 computers and I run an instance of my thumbnail generator code on each. One computer hosts the images. The other two computers access the folder of images via the network. My code is written to compare the main folder and a thumbnail folder to see if new thumbnails need to be generated. If so, a thread is generated and the thumbnail generation code is ran on the thread. There are 5 threads created in all. So, theoretically, across 3 machines, I'm getting 5 independent threads and I'm thinking that Windows 7 automatically spreads the load across the local cores. In an effort to avoid duplicating work, the comparison is done before the generation of each thumbnail.
This method is faster than using only one computer but drags down the performance on all computers (THE UI also becomes unresponsive). I'm looking for a better way to
1.) Produce the thumbnails as fast as possible
2.) Keep all UI's responsive (boy possibly controlling the priority setting) and
3.) Done within a single instance of the program.
In the #3, I mentioned that I would like to use one instance. Is it possible for networking information be used by the hosting computer that will allow threads to run on the other 2 computers? This way, the 15 threads will be controlled by a single host computer.
Here is a snippet of my

It is for sorting and array for 12 numbers, which are being enter by the user via a input box.

Fastest Method Of File IO And Content Manipulation?
Apr 20, 2010My current project is to process several files. The files come from a Unix server and have been SFTP'd to the Windows XP machine. (That's fixed protocol, I don't have control over it.) My problem now is that the Unix new line characters and Windows characters don't match. The solution is to read the file line by line and replace 0x0A with 0x0D + 0x0A, or Asc 10 with Asc 13 + Asc 10, or vbLf with vbCrLf, however you like to say it.Well I have a working function to do this, but any extra speed I could squeeze out of it would be fantastic. The text files I'm working with can reach sizes of about 100MB. So to the question:
Q: What is the fastest way to read a file in, change characters as necessary and then write the file out?Here is my current working code.

Dim item As New ListViewItem

Fastest Alternative To Datatable.Select To Narrow Cached Data?
Sep 28, 2009I have a search function on my company's website (based on .NET 2.0) that allows you to narrow the product catalog using up to 9 different fields. Right now, after you make your selections on the frontend I am building a dynamic query and hitting the database (SQL Server) to get the resulting list of items numbers. I would like to move away from hitting the database everytime and do all of this in memory for faster results. Basically a 3500 - 4500 row "table" with 10 columns: the item number (which could be a primary key) and the 9 attribute fields (which have repeating values for many many rows).
There can be any number of different searches between the 9 columns to get the items you want:
Column A = 'foo' AND Column D = 'bar'
Column B = 'foo' AND Column C = 'bar' AND Column I = 'me'
Column H = 'foo'
etc...
Based on my research, the .Select() function seems like the slowest way to perform the search, but it stands out to me as being the quickest and easiest way to perform the narrowing searches to get the list of item numbers:
MyDataSet.Select("Column B = 'foo' AND Column E = 'bar' AND Column I = 'me'")
In my specific case, what method I use as an alternative that has the same narrowing functionality and better performance instead of settling for the datatable.select() method?
