I know this is simple for most of you guys but I'm not sure I even have the concept right, so here goes...
1. Read in a txt file that has 1 piece of data per line, I got that...
2. Count the number of items, I got that... :
3. store the count and the items in memory .. I think this is for an array 
4. later I use the index to send the item through multiple query's in an SQL database ... got that hard coded right now and it works great
It is step 3 that I am stuck on conceptionally and technically.
Questions
1. Is an array the right thing to be doing here?
Any suggestions, thoughts or instructions would be greatly appreciated.
TIA

Any reason for getting the number of items and storing it in an array?
For me, I would have skipped step 3. I will read the data per line and write it straight to the database once I read from the text file.
The only catch with this way is that if you encounter any errors in between you will not know the last position of data that you read from the file. But this can be prevented by using DB transaction during your database entry.
Cheers,
DePatrick

Like the other poster suggested, skip step 3. It is not really needed and is redundant.

I am guessing this is a study assignment, and you were asked to create an app according to these steps.
Under this assumption:
If you have managed step 4 then apparently you are also, perhaps unwittingly, already doing step three.
So the question is: how do you iterate through the items at the moment when running them through the queries?
The purpose of step 3 was probably to enable you to write a loop, for example using an array.
Something like:
<br />
For i As Integer To NumberOfItemsCount -1<br />
RunYourQuery(ForExampleAnArrayWithItems(i))<br />
Next<br />
So once again, as you have managed step 4 already, point 3 is moot, unless your teacher/professor meant for you to iterate though the items with a For loop.
If I assumed wrong about the assignment thing, ignore this and listen to the other guys.
Good luck,
Johan

Johan thanks for the reply.
I am iterateing through the db query's using the method you described. I have multiple files to read from and was wondering if a memory representation of each of the files would be a better approach?
Thanks again

That is a trickier question.
Theoretically speaking the amount of files could be enormous, and the amount of items in each file could be enormous, (EnormousFileAmount x EnormousItemAmount = HumongousDataQuantity) therefore it would not be advisable to first load all files into memory.
However, the scenario probably is something along the lines of electronic order files, which means that the app would never be handling more than a limited amount of files at any given run.
Connecting many times to a data source (your files) and doing a little work each time is generally speaking slower than making a single connection to a data source and doing a lot of work at once.
However...
Because you are accessing files, you need to make a separate connection to each separate file anyway, so that point is also really moot.
Which brings us to the advantage of many connections and little work each time: data integrity.
I.e. if a connection is interrupted for whatever reason, you loose very little work, and when you are using loops inside loops, there is much less danger of information getting mixed up.
P.S. pointer for extra credit: use System.IO.File.Move("FileLocation/FileName", "ArchiveFileLocation/FileName"), when handling multiple files.
My advice is free, and you may get what you paid for.

You can use a hook to capture the clicks. There's code here[^] to disable right-clicks. Just need the hWnd of the webbrowser control.

hi
share the database example dbshare
and set the connection string
"provider=microsoft.jet.oledb.4.0;data source =\\75.126.169.130\dbshare\main.mdb"
|
|
|
|
|
thanks for all first
did you mean Virtual Directories?
|
|
|
|
|
|
yes
'\\00.00.000.000\mydb\db.mdb' is not a valid path.
|
|
|
|
|
Then there isn't anything wrong with your code. You just don't have the correct path to the database.

hi blackeyes
It seems you dont understand the Basics, but now we cant teach you.You have to find out your self by reading.Check one of the Following Articles on how to connect to a Database. secondly never post your Connection string with your real IP, you dont know who is reading. lastly to Connect to the a Database in .NET you just import the necessary classes , for you case its oldedb and declare a connection string and assign it to what you just showed us and lastly it depends what you want to do with that connection, select ,delete, insert, ? then you have to create command objects for your queries and execute them. see my articles on that

Thanks for the reply.
But frankly speaking, I know a function named MousePosition which works the same way as this one GetCursorPos but what I wanted to do is to get MouseMove event even mouse is not on WebBrowser control.
Well, however I have resolved the issue myself so once again for the help.

I got struck in a point in my current project. Any help will be appreciated.
I am using Crystal Reports in Visual Studio 2005 Professional Edition to create a chart.
Bar charts are used to show up the data analysis. But I haven't found any option to change the color of the bars. It’s picking the colors automatically. I want to change the colors in custom order, based on my data.
Any Idea?
Thanks in Advance
