How to get the Database Driver list

Hi... I want to know that particular database driver is registered or not in windows.. how can i get this info.
And I want to get the list of all the database drivers registered in windows..
Can anybody help me..

Well, seeing as how none of them are registered, until your program registers them, simply keep a list.That's not actually true. If the JAR is in the classpath then a JDBC4 driver will use the service provider hooks to register itself.
When first loaded. Which is unlikely to happen until you explicitly load it.
Being on the classpath doesn't mean the JVM will actually do anything with a class. Either an application will have to initiate some action or it will have to be initiated by the manifest of the jar (and I'm not sure that will actually do anything until a class from that jar is actually required to be loaded).

How to get the Database type from weblogic Db connection

I want to use database version control in my application . that means different database type use different Sql Statement. Such as in weblogic7.0 if I create SqlServer JDBC pool then I will use some special Sqlserver sql Statement . such as some join statement. If I create Oralce JDBC pool then I have to use different Sql statement . because these two database support different Sql statement.
What my question is how to get the database type from the connection.

For a normal jdbc driver you can use
Connection.getMetaData()
To get the meta data, in particular the getDatabase...() methods.
That might or might not work.
However, at the very least in the server you have access to the weblogic properties so you can parse the pool property to figure it out.

How can I getting the system drives list?

Hello again. I'd like to create a dropdown list with the computer's drives, so you can easily change from one to another without using a "selectDialog" File object. Is it possible?
Thanks beforehand :)

Its something I havn't tried.
On a PC you might be able to use VB/VBS to get the file list, put them in an env so that you can read them from Javascript.
Here is a bit of code found on the net.
Set FileSystemObject = CreateObject("Scripting.FileSystemObject")
Set Drives = FileSystemObject.Drives
For Each DiskDrive in Drives
DriveLetter = DiskDrive.DriveLetter
DriveType = DiskDrive.DriveType
Select Case DriveType
Case "0" DriveType = "Unknown type of drive"
Case "1" DriveType = "Removable drive"
Case "2" DriveType = "Fixed drive"
Case "3" DriveType = "Network drive"
Case "4" DriveType = "CD-ROM drive"
Case "5" DriveType = "RAM Disk"
End Select
WScript.Echo "Drive " & DriveLetter & " is a " & DriveType
Next
Set Drives = nothing
Set FileSystemObject = nothing

URGENT: how to get the database error message into application?

Hi, pls give some idea:
For example, the database is MS Access. When insertion failed, the getMessage() method of SQLException will print "General error", while the log file created by ODBC will be "[MICROSOFT][ODBC DRIVER]column ID no found in student table"(...just a example).
So, how to get this message in our application?

instead of using the getMessage method, have you tried something like this:
         try {
         } catch (Throwable t1) {
            System.out.println(t1.toString());
         }If that still doesn't work, you can always redirect the log entries into a textarea but then everything that appears in the log file will be redirected!

How to determine the database driver a report uses?

Hello experts. I'm using Crystal Report XI R2 and C# (.net 4.0 runtime).
For a given report, I'd like programmatically determine what database driver(s) a report and it's sub-reports use. The nice thing is that I don't want to change it.
When I refer to database drivers I'm talking about the choices one gets when starting a new report in the Crystal UI. Something like the following:
Access/Excel (DAO)
ADO.NET (XML)
Database Files
ODBC (RDO)
OLE DB (ADO)
I've looked into the developers help file that came with Crystal XI R2, crsdk_net_doc.chm, and can't find any references that would help. Maybe it's what I'm searching on.
My goal is for a given directory produce a list of rpt files that use OLE DB and a MS-SQL Server provider.
Thanks for looking at my question, any assistance is appreciated.
Mike

Also note since you are using 4.0 framework you must also be using VS 2010.
CR for VS 2010 is the only version supported with 4.0 framework.
See this page to download it: http://www.sdn.sap.com/irj/boc/crystalreports-dotnet
Or go back to VS 2008.
Code would look something like this:
     public class frmMain : System.Windows.Forms.Form
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc;
New subrepoutine...
            ISCDReportClientDocument rcd;
            rcd = rptClientDoc;
            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo oldConninfo;
            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo newConnInfo = new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();
            CrystalDecisions.ReportAppServer.DataDefModel.Table oldTbl;
            CrystalDecisions.ReportAppServer.DataDefModel.CommandTable newTbl = new CommandTable();
            oldTbl = (CrystalDecisions.ReportAppServer.DataDefModel.Table)rcd.Database.Tables[0];
            oldConninfo = oldTbl.ConnectionInfo.Clone(true);
Thank you

How to get the table/tree/list cell underneath the mouse

I feel like I must be missing something. How can I find out the tree cell underneath the mouse cursor?
I am implementing drag and drop from a table to a tree. I need to know which tree cell the user dropped the item on. I can get the drop coordinates (in pixels, I assume) from the drag event, but there doesn't seem to be a way to convert that into the particular cell index. This same question applies to getting the list and table cell under at particular coordinates.
If there isn't an API for this, has anyone found a reliable workaround (dividing Y by cell height, etc.)
Thanks,
Josh

You need to put event handlers for the D&D events on the Cells that are being created (so you will need to set a custom cell factory). For example, every cell is a Node, and these support properties like 'onDragDroppedProperty', and 'onDragExitedProperty'.
When you add event handlers to these, you should be notified of items being dragged onto specific Cells of the Tree. A Cell then can be matched with a particular item in the Tree by reading its TreeItem property.
Also read the documentation for TreeItem. There is a bit there that says:
"It is important to note however that a TreeItem is not a Node, which means that only the event types defined in TreeItem will be delivered. To listen to general events (for example mouse interactions), it is necessary to add the necessary listeners to the cells contained within the TreeView (by providing a cell factory)."
Which gives a clear hint at the end that for other interactions, you should add listeners to the Cells.
Good luck!

How to get the database value without submitting the jsp page

Hi,
I have a form that has many fields (textbox/listbox). when user enter/change a value in the first textbox, I need to pass this value to the database to check whether it exist and get the other values to be displayed to other fields in that form (i cannot get the javascript value to be pass to jsp without reload/refresh/submit. But, I need to get the user entered value, so I thought of hidden popup, iframe, etc but not sure how I could apply and which best suit this case). If I submit the page then I can easily get the value thru 'request.getParameter("fieldname") but cannot use this because I cannot submit the page.
Pls help and possible provide me with the sample coding
Thanks

The best way for you is surely AJAX. But there is another way to stay compatible with older browsers:
Since the default method a browser supposed to get data is refresh, there is nothing unnatural in it. Browsers are optimized to refreshes, like cached images, etc..
So for these step-by-step things, you need to roll forward your data from page to page, and make the page to respond according the data it actually have. This can be easily achived with type="hidden" input fields in a form: the user will send you back all the data. Optionally you may show him the data you already have as visible text too.
A more generalised way to "pull" the data: you make a whole page you include every time you need an additional data. This page will receive 2 parameters from where you've included it. This 2 parameters are each indexed arrays with the datas you have to pull in (here the default value), and you need to push forward. Optionally there is a 3rd parameter, the url it have to return (as the form's action property).
And for them who now say that it would me more culture way to store this data in the session: Beware! Common mistake: Sessions are to store data about the user itself, not the datas for the next page! You never know what will be the next page! The user click some backward button and refresh button, and depending on your script, it may go stupid! Ok, not all the codes, but I've seen some. It's ok to store a sent file (fx. image) on the server, but always think the evil refresh and back buttons!

How to get the amazon book list design with the RowRepeater

Hello,
at the moment I am programming a small book management application. After the fight with the row repeater (that at least was a bug in the rowrepeater) I would like to have a desing like the amazon-list:
http://www.amazon.com/s/ref=nb_ss?url=search-alias%3Dstripbooks&field-keywords=sap
Could someone tell me how I can achive this?
- How can I use the Image with the url to the image.
- How can I get the title as link to a view that shows the details of the book (is it LinkToAction? if yes, how can I pass a parameter?)
- How can I get the design with 2 cols and for the text new lines?
Thank you very much in advance and have a nice week,
Vanessa

How can I use the Image with the url to the image.
With image you cannot have URL. You have use Image UI element and you can place an linktourl element below the image.
How can I get the title as link to a view that shows the details of the book
For links, you are right . You have to use LinkToAction UI element. On the Action of Link , you can get the value selected by reading the attribute binded to that link.
How can I get the design with 2 cols and for the text new lines
For columns , you have to use Table UI element.
For designing you view according to the requirements , you can use various UI elements :
Tray , Group , Transparent containers. These would help you in making specific containers or grouping particular set of elements together.

How to get the iChat Buddy List to automatically appear on the Desktop

On my friends computer iChat is set to launch whenever he logs into his account, but the Buddy List does not appear on his Desktop. So when I see him online there is no green video camera mark next to his name.
If I want to do a screen share with him, I have to ask him to go to the iChat icon towards the right side of the Menubar (the round 'speech ballon') and click on Show AIM Buddy List at the bottom. Once he has the Buddy List on his Desktop, I can screen share with him.
Surely there must be a way for the Buddy List to always appear on the Desktop when logging into his computer... Can anyone help out?

Hi,
Interesting one.
If I were telling you how to create this it would be like this:-
1) Go to System Preferences > Accounts > Your account and enter iChat in the Login items. (Makes iChat launch at Computer Start Up)
2) to Hide the Window (Buddy List(s) ) at Start Up click the Red Button to close the Window/Buddy List before Quitting.
This will cause the next Start Up to not show th Buddy List.
How you make the Buddy List appear after that depends on how you bring it in to View.
NOTES:
Some Windows in iChat from Buddy List to the Preferences to th Actual Chat Windows will appear in the places you left them for the most part.
The Exceptions are Incoming Invites.
This means the Buddy List will be were you left it, your Outgoing Invite/Preview whilst waiting for Connection will always be where the last outgoing Video Chat window was.
Using the Red Button on a Open Chat Window will end the Chat (All types).
However doing it to a Buddy List only Hides it.
In addition to this using the Item (or the Keystrokes) from the Window Menu of iChat for a Buddy list when it is On view will Hide it (or Bring it back if Hidden)
The Show AIM option in the Menu Bar icon's drop down is a two edge thing as it shows All Buddies (Available ones) from all AIM Buddy lists if you have more than one (Apple names are also AIM Names in this case).
Does he want to change this Behaviour ?
He would be better off using the iChat Window menu (or Keystrokes) after he has clicked the icon in the Dock to bring the app to the Front so he can access the Menu bar with ichat in it.
He could also click and Hold the icon for iChat in the DOCK and select the Account Name there. This, if I remember correctly, will have the same effect as presenting the Buddy List from the Menu Bar icon (it will be hidden at Next Start Up)

"The database size" can be
- the total size
- the filled size
- the filled size without undo/temp
You can use DBACOCKPIT to centrally manage multiple instance and check the sizes.

How to get the Database size?

Hai Friends,
I have created a Z Table with 100 fields. i want to check the database size after uploading the data. How can i do this?. That is, after uploading the first entry i want to know the size and again i want to upload 5 more entries and to check the growth.
Where can i see this?. i have checked in DB02 but even after data upload i didnt see the size. kindly explain me the process.
Thanks..................

Hi,
In the Go to Menu then Check the Number of entries to track your current set of entries.
For DB Size check Technical Settings . Tab Logical Settings parameters the Data class and Size category can give you how much data the table can hold.
