How to extract the mouse cursor image without using JNI

I want to get the image of the mouse cursor of the system using java. The Robot class captures the screen only, but the mouse icon image is not the part of the screen, so it is not easily detected. But we can get the mouse cursor position using API, but how to get the exact image icon, without using JNI. I don't want to generate my own cursor at that position.

I am building a Remote Desktop kinda app using java..... I want the screen of the remote comp to be viewed on my screen and generate events from my machine to the remote machine. So, I am capturing the screen images of the remote machine. But the cursor is not part of the screen object. i want to extract the cursor image icon from the remote machine to my machine and render the image.

Could anyone tell me how too change the mouse cursor to the waiting mode?

Could please anyone tell me how too change the mouse cursor to the waiting mode while my applet is processing?
Well i have 3 combos in my applet.....and in my actionPerformed code i have:

if (e.getSource() == combo1) {
          setCursor (Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
ind_reg = combo1.getSelectedIndex();
Do_Accion1();
setCursor (Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
if (e.getSource() == combo2) {
setCursor (Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
ind_mun = combo2.getSelectedIndex();
Do_Accion2();
setCursor (Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));

How to change the mouse cursor icon type when mouse moves out of client area ( propertysheet) WTL?

I got stuck with an issue in property sheet .I want to load different cursor when the mouse position is within the client area and load another when moves out of the client area.
In the porpetysheet I added four page. In the first page when I click next I am loading cursor of IDC_WAIT type and loading IDC_ARROW when the mouse moves out of the client area.
In the page class I triggered the event for WM_MOUSEMOVE as follow:
MESSAGE_HANDLER(WM_MOUSEMOVE, OnMouseMove)
LRESULT OnMouseMove(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
if(TRUE == m_bIsNextBtnClicked)
::SetCursor(LoadCursor(NULL, IDC_WAIT));
else
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return TRUE;
This event is getting triggered and absolutely had no issue with this. Similarly I tried adding `MESSAGE_HANDLER(WM_MOUSELEAVE, OnMouseLeave)` this event making an assumption that this will get triggered if the mouse moves out of the client area, but
this event did not get triggered at all.If this is not the mouse event to be triggered for mouseleave which event should I trigger?
LRESULT OnMouseLeave(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return TRUE;
Now when I click Next button , **I was actually calling a function which is taking sometime to return** . Before to this function I am loading IDC_WAIT cursor i.e.,
`::SetCursor(LoadCursor(NULL, IDC_WAIT));` .
Now when move the mouse cursor on to the non-client area I want to load IDC_ARROW cursor i.e.,
::SetCursor(LoadCursor(NULL, IDC_ARROW));
When the moves on to the non-client area I am handling the mouse event in sheet derived class as follows,
MESSAGE_HANDLER(WM_NCMOUSEMOVE, OnNCMouseMove)
LRESULT OnNCMouseMove(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
::SetCursor(LoadCursor(NULL, IDC_ARROW));
return 0;
This event is not getting triggered until unless the function in the Next button event is executed.
I want both of them to be done in parallel i.e, click Next button now hover mouse on the client area, Busy icon should come and when mouse moves out of the client area then IDC_ARROW icon should come.
LRESULT OnWizardNext()
::SetCursor(LoadCursor(NULL, IDC_WAIT));
m_bIsNextBtnIsClicked = TRUE;
BOOL bRet = MyFun();
m_bIsNextBtnIsClicked = FALSE;
//Until this function(MyFun()) is executed **WM_NCMOUSEMOVE**
//event is not getting triggered.But this event should get triggered and I
//should be able to see the change of cursor within and out of client area.
Can anyone kindly help me to solve this issue.

How to extract the number from image using java

Hello every one
i want to develope a project which can extract the number from image
that i can use as inter or String or char.
Is there any API in java which provide this type of facility.
right now i m using java 5
thanks in Advance
Jignesh

In my project i have a image in that i have a
co-ordinate (x,y) I am still puzzled as to what you seek. It sounds to me like you have a point (x, y) represented by p. in java it's just p.getX() p.getY()
i want to convert that cordinate to numeric form,
i mena i want to use that cordinate in somewhere else
in project.point.getX() point.getY()
So need to convert it into numeric form u can called
it OCR also.OCR is optical character recognition. If I want out and took a picture of the US Declaration of Independence and then wanted the words on the parchement in the picture in text form, then I would run the picture through a software program and it would try to optically recognise what lettering and number were present in the picture. In the end, I would have a text of what is written on the US Declaration of Independence.
Is that what you want?

How to read the contents of images folder using AS3

Hi,
I'd like to load the images in the folder dynamically without using XML.
Is there a mechanism in AS3 that enables me to read directly the content of images folder directly without using XML or should I use php to do that?
Thanks

Yes you can do that without XML. You need to use the Loader() class to dynamically load the images. Check the documentation of the loader class.

How to extract the content of a section using VBA?

For example, I have an article like this:
Abstract
AbstractParagraph1
AbstractParagraph2
Body
BodyParagraph1
BodyParagraph2
Reference
ReferenceParagraph1
ReferenceParagraph2
Knowing that Abstract, Body and Reference are all headings, which means if I click the triangle button on the left of the heading (For example, Abstract), AbstractParagraph1 AbstractParagraph2 will shrink or expand. So my question is: how to retrieve the paragraph
in a specific section using VBA?

Hi UW,
>> how to retrieve the paragraph in a specific section using VBA?
In my option, you could use the Section Object (Word) to get the section object, and then use the Section.Range Property (Word) to get the content of the special section. The links below might be useful to you.

i want to read all the exe files which are below this location.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
I found solution for how to read the following files Example: (AcroRd32.exe and firefox.exe, etc);
which are located in the below path in registry.
by specify the location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\AcroRd32.exe
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\firefox.exe
by using the RegOpenKeyEx() function.
But now i need to list all the exe files which are under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
Example take Acrobat reader and firefox are the softwares installed means it has to list
AcroRd32.exe

Can anyone guide me how to create the databse with or without using the GUI

I need to create the Database from SQL prompt can any body tell me the links where i can find some sample scripts to do that....Thanks

Hi,
I would like to mention few stuffs too..
for manually.
1. startup nomount pfile=path of the pfile.
2. run the create datbase script.
3. run catalog.sql, catproc.sql script.
that was the brief idea,but you need to create your sample pfile,setting up your dir locations,setting envrmnts variables.
for gui envrmnts you have DBCA , use it and forget about all the cavtes.
thanks
Alok.

Does anyone know how to simulate the GET PERSON event without using PNPCE?

I need to modify report is RPCGRNU0
About line 109, it does GET PERSON, then sets a flag to true. Then once the GET PERAS event starts, it checks if the flag is true or not.
Edited by: Christian Rios on Apr 2, 2009 5:43 PM

what exactly are you trying to do? Copy RPCGRNU0 & modify it? why do you need to simulate the GET PERSON event?

Mouse Cursor Image

Hello All,
I have read that java.awt.Robot class does not capture the mouse cursor image when the desktop snapshot is taken, and I wanted to see how developers are getting around with this. Is a pure Java solution possible or they use JNI?.I have read that developers try to draw image of mouse cursor image at given x,y on the desktop image. What's the final possible solution?
Thanks
Nitin

NitinThis has absolutely nothing to do with JMF, and you answered your own question. Take the screenshot and draw a cursor where the cursor should be. BufferedImages are easy to draw on.

Count the no.of rows without using count function

Hi,
How to count the no.of rows without using the count function?
Thanks,

they won't be 100% accurate. You're correct, Bluefrog, but the same goes for doing a count(*) (depending on the size of the table, ofcourse):
the table being queried might be under DML (deletes/inserts), and the next count(*) might give different results.
Both approaches will never be 100% accurate.
But simply selecting num_rows will be much much faster than doing a count(*).
Counting the number of rows always reminds me of this ongoing discussion, by the way:
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:127412348064#14136093079164 ;)
Usually knowing the number of records by approximatly is sufficient, imo. 1000000 or 1000007 records: I don't care, don't need to know that.
I've never needed to know the exact number of records in a table in my code, or been given a requirement that forced me to.
