Need a little more clarification. What is the requirement for having all of the lines stored in an array? What are you trying to do with all of the lines once they've been read in?

ok...
i want to get a part of single line with MID,LEFT,RIGHT ecc and store the piece of line in a var.
About array mode, is simple one suggestion.. in Google i have seen with FSO is a good way to speed the reading or not?

I, like Paul, still wonder why you need all the lines in an array?
Do you really need all the lines in memory at once?

FSO? Are you using VB6?
Despite everything, the person most likely to be fooling you next is yourself.

I am still waiting for a real answer to that question I asked him. His requirements still make little sense other than picking off pieces of the text, but why everything all at once?

To benchmark how fast the memory can be filled?

More along the lines of what is the purpose of reading the entire file into memory at once.

Hi,

No!
File.ReadAllLines will read the file and give you the huge array you are looking for;
however generating such a huge array will be detrimental to the performance of your app, no matter how you do it.
If a single pass through the file is all you need, have a look at streams. If you only need a fraction of the file's content, read it line by line, don't store all the lines, simply store the pieces you need (use StreamReader.ReadLine)

When you say "import", what *exactly* are you implying. Are we talking just getting the data from the file into your app to use variables/collections of some kind. Then I would agree with the above, that using a streamreader and reading line by line would be the best bet.
OR, if your goal is to get this data into a DB like SQL? If this is the case, I would scrap what you're doing an look into DTS/SSIS since both give you programmatic control of the data coming in and format/manipulate as needed. Speed wise, there's not even a comparison.

GetPointOfView is an integer but reports in degrees.
example
up returns 0
right returns 9000
down returns 18000
left returns 27000
sound simple enough, but as we know it will not give value over 32767. In this case it is max out at 31500. so i am losing degrees 31501 to 3599.
I do not seem to be able to change the GetPointOfView to anything other then an integer. Anyone noticed this before?

That's odd. I've never really worked with DirectX and MSDN didn't seem to say much about that  Wondered if degrees 31501-35999 would be represented as negative integers but MSDN says -1 represents being centered...

Question?
if the value went negitive would i not get 7FFF?
I am just learning this VB express. I really did not like it at first but it is groing on me. Maybe you can teach old dogs new tricks.

Only if you converted it to hexadecimal.

I answered my question.
I did not notice but it is reporting back in 45 degrees. I was only interested in 270 to 360 degrees.
Thanks to all how helped.

Hi
I have developed a toolbar which needs to invoke a javascript function based on some criteria on specific web page.
To be simple, I want to know how to invoke javascript from BHO(using VB.NET).
I have done everything already but just this one needs help.
Thanks in anticipation

Does Crystal not come with any sort of help files ?

You have to either install CR9 on the machine, or build your app's installer to include the CR9 runtime. This is all documented in the CR9 documentation.

Hi all...
I am creating a simple,small image editor program.
I have almost completed my program but except one thing.
I have associated .jpg files to my program (using registry editor).
Now, the main thing is that when I double click on any .jpg file, my program gets open but that image is not open in my program's picture box.
I want to do that when i double click on any .jpg file, that .jpg file would automatically open in my program (appear on my application's picturebox) for editing rather then loading .jpg file through my application manually.
Thanks.

When you double click on the file, Explorer launches the associated application with a command line like this:
MyApp.exe "C:\FullFile\path.jpg"
Your application has to process the command line arguments to get the filename to open. It doesn't happen automagically.
A quick Google will give you a ton of examples -> "VB.NET command line arguments"[^]
