Hi All,

Find the kind of collection you want on MSDN and you'll see a line like this:
Indexes in this collection are zero-based.
If you want absolute definite confirmation you need to go to the source. You can also write some code to see.

|
|
|

It is starting with 1 I am expecting. I guess its correct. Thanks for the help.

If you're unwilling to write some code to test something so simple, you probably do your employer a disservice by naming them in your sig.

Ditto to JZ.
Pretty much everything is zero based. If there's any doubt in your mind, simple create the collection and add items to it. Then do your own testing iterating through the collection.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Why don't you just try it? Create an instance of the object and loop through it in your debugger?

As you suspected, those previous replies are all wrong. They're trying to mislead you for fun - don't listen to them. Fortunately, i'm here to give you the straight dope no problem: the starting index of a System.Collection object is 143. Always 143. Except in leap years on odd-numbered days of the month: then it's 2 - this is a subtle bug in many programs, so be sure you add code to test for it. You can usually speed up these checks by storing all such dates in a database table (i recommend using Access), and just querying for them before you start iterating on your collection.
That's it - no big deal, eh? Carry on, brother man!

Let's discuss something similar. Are integers are integers?
I'm too lazy to test int i="sdafsaf"; too.
OK,. what country just started work for the day ? The ASP.NET forum is flooded with retarded questions. -Christian Graus

Whenever you have such questions in your mind, Just try accessing
Console::WriteLine(yourObject[0]);
Make sure you enclose it with try{}catch{}.
If an exception gets caught, and if the message looks something like "Bloody s*cker you can't touch my a**", it's definitely 1 based.

Yes it is Possible.
Make a For Loop from i=0 to gridview.rows.count-1
insert into transition values('"& ctype(gridview.findcontrol("ComboBox1"),DropDownList).selecteditem.text &"','"& ctype(gridview.findcontrol("ComboBox2"),DropDownList).selecteditem.text &"','"& ctype(gridview.findcontrol("TextBox1"),TextBox).Text &"','"& ctype(gridview.findcontrol("TextBox2"),TextBox).Text &"','"& ctype(gridview.findcontrol("TextBox3"),TextBox).Text &"')
Try & if still not working then reply

You can bind gridview with query from coding
For e.g.
dim da as OledbDataAdapter
dim dt as new DataTable
dim st as String
'Enter Connection String
dim cn as OledbConnection("")
st="select a.name as Name,b.Address as Address from student a,info b"
da=new OledbDataAdapter(st,cn)
da.fill(dt)
Gridview1.datasource=dt
Gridview1.DataBind()
and while Adding the ComboBox Column in Gridview You can Give DatatextField= Name & DataValueField= Address
Same for ComboBox2 Column
Try if Still Not getting then tell so i can give u my phone no so u can call me.

What u said was right, but the problem is

Column2-specification (combobox)
Column3-shape (combobox)
Column4-prize
Column5-remarks
Tables1-t01customerorder
Table2-m01specification
Table03-m02shape
In load event-All above columns are retrieved from transaction table –t01customerorder
If we click new button column2 as get data from Table2-m01specification
And column3 as to get data from Table03-m01shape, after selecting the value from master table
Column1, column4, column5 –user input
Click save button, selected data from master table and user input get saved into Tables1-t01customerorder
Please help me to achieve task
Thank you one’s again

Hi,
I'm using VC6.0 DLL with VB.NET. XYZClient.dll is in the same directory as the VB.NET exe is present. But, still I get this runtime error on some PCs.It works on couple of PC without any issues. I tried on Windows XP as well as 2K. Results are intermittent. Any idea?
In VB, function is decalred as below:
Declare Function XYZOpenConnection Lib "XYZClient.dll" (ByVal IPAddressOrMachineName As String, ByVal usernameOfXYZUserGroup As String, ByVal applicationData As Integer) As Short
Thanks
Vikas

you can use the dependency viewer to look at the files on which XYZClient.Dll is dependent on.
I guess on some of the machines these files are missing.

Do you need the VC++ redistributable installed on those PCs?
