I would to compare the value from the certain column, row of 2 different text files. I have already stored into them to 2d array. Any idea how to start from scratch so that i can compare them? It involves the complicated for loop or do while loop.

I don't see what the question is. If you have them in a 2D array, then use the right indices to compare the values that need comparing ? Perhaps you need to explain more.

For example:
For File A.txt and B.txt, I have already stored the value from certain row and column of A.txt and B.txt into 2 D array by using the do while loop. For A and B, they got their own do while loop.
If i compare the value outside the do while loop, the 2d array would get the undefined value. They cannot be compared at all.
If I put both of the A and B in One do while loop, it will become complicated.

So, create your arrays THEN use those arrays to lookup the values you want to compare.

Q1/If this is the path to save an open Excel file running in the background
xlSheet.SaveAs("c:\My Path\tk" & Format (Me.MonthCalender1.SelectionStart, "yyyyMMdd") & ".xls")
How would I open a file using the MonthCalender1 (Change-Date) as the trigger to determine the name? e.g. "tk20070727.xls" ?
Q2/ Having opened the file (running invisable in the background), how can I pull the data from a cell to a variable?
Q3/ How do I close the invisable running .xls file in runtime?

So how many times are you going to post the same question(s) in one day? Yes, it's considered very rude.
I don't do Office Interop, so my experience with it is VERY limited.
But, I'd image you would find the Open method on a Workbooks collection. You'd have to pass it the complete path to the file you want to load. It looks like you already know how to generate the filename you need.
Pulling data from the cells would probably involve something about a Range object with, maybe, a Cells collection that holds a bunch of cells, and possible a Value property of each Cell.
There's a ton of examples out there. All you have to do is Google for something like "vb.net Excel workbooks", or "vb.net excel Range object", "vb.net excel retrieve cell values".

Thanks Dave for you compassion and understanding. I hope you have a wonderful day and everything goes the way you'd like it too.

You have to manualy release COM object to kill the excel process running in the background.
Say your Excel.Application object is myApp. Then use this:
<br />
myApp.Quit()<br />
System.Runtime.InteropServices.Marshal.ReleaseComObject(myApp)<br />
System.GC.Collect()

Thank you very much Neoh, it is good to get someone to help with this stuff.
Some people would rather abuse Newbies than spend the same time making the world move a little faster by helping them.
Google is great but doesn't always hit the nail on the head, and asking questions for help is what I thought this site was about.
Again many thanks mate, you're a champion!!

I'm populating a combobox "ChargeName" by datasource depends on the item selection of another combobox "ChargeDegree", the combobox "ChargeName" indeed displays the list of items I expected depending on the "ChargeDegree" combobox selection. However, when I select the "ChargeName" combobox to print out, let's say, on a label or on a grid cell, strangely it displays "System.Data.DataRowView", instead of the supposed item of a Charge Name I selected.
Dim sqlCharge As String<br />
Dim dbGate As New databaseGateway()<br />
Dim dsCharge As New DataSet<br />
Dim chargeDegree As String 'the degree of the charge<br />
<br />
chargeDegree = cbxChargeDegree.SelectedItem.ToString()<br />
sqlCharge = "Select ChargeName from Charge where ChargeDegree = '" & chargeDegree & "'Order by ChargeName"<br />
dsCharge = dbGate.ExecuteQuery(sqlCharge)<br />
cbxChargeName.DataSource = dsCharge.Tables(0).DefaultView<br />
cbxChargeName.DisplayMember = "ChargeName"<br />
cbxChargeName.ValueMember = cbxChargeDegree.SelectedText<br />
cbxChargeName.SelectedIndex = 0
Does anyone know why this is it?
Please Help Me. Thank You Very Much. Ryan

Hi,
By default the ToString returns then Namespace.ClassName of the object, you could change this behavior by overriding the ToString function (In case you design your own class), in your case try to use the following:
chargeDegree = cbxChargeDegree.Text
hope this helps

Thank You, but it still doesn't work. I think the problem is one of the following syntax:
cbxChargeName.DataSource = dsCharge.Tables(0).DefaultView<br />
cbxChargeName.DisplayMember = "ChargeName"<br />
cbxChargeName.ValueMember = cbxChargeDegree.SelectedText<br />
cbxChargeName.SelectedIndex = 0
The chargeName combobox does has the items I expected upon the selection on the chargeDegree comobox, but strangely the text string display is "System.Data.DataRowView".
Can anyone else help me, please?
Thank You Very Much. Ryan

You need to find a source for stock info, obviously.

Hi,
XML is the best technology for data interchange, look for a provider that publish the data in XML format and the rest is easy.
Good Luck

 ArrayList contains the row of data as its items. How to iterate through the lines, split each and store the data(array of columns) as new item in the ArrayList? Please provide example.
|
|
|
|
|
Hi,
I am not sure if you I got you right, please post your code to make your question clearer, for now you could iterate using the Count and Item properties:
'Abstraction
Dim c() As Columns
For I as Integer = 0 to coll.Count -1 'coll = ArrayList
c = coll.Item(i)
'Process your columns here
For J as integer = 0 to c.Length -1
... c(J)
Next
Next
hope this helps

In c#, the syntax is sth like this
(arry_List[3] as string[])[2]
arry_List[3] - the fourth item in the ArrayList, meaning third line.
the [2] means the third item in the columns array.

Anything written "In c#" is not really a good idea to have in the VB forum.

You've asked this a few times, I really don't think you'll have much luck.

Is there any tool to decomile dll into its native code.
Or else any tool to find what traffic was going between the sybase server and the application in my local PC.
Awaited for ur reply

That depends on what it was originally written in. If it's a native code, not managed code (.NET Framework), DLL, there are tools that will TRY to reverse the code back into something like C or C++. Anything else and you're pretty much SOL. A Managed code .DLL, you can use Lutz Roeder's .NET Reflector.
In either case, you will NOT get the orignal code out of the compiled product. You'll get something that resembles it, but it will not be perfect. You will also not get any comments, original variable names, documentation, ...
Basically, you have a huge handicap. If you don't know the structure of the database, you're just guessing at what you need to do. If you don't have the documentation on those .DLL's, again, you're just guessing at how they work.
