How to Clear all the data of open windows form of another exe?

Hi,
I want to make utility which will clear all the data from one windows application.
i know the application name. The application of which data i want to clear is made in C# and contains many windows forms and controls.
out of that opened windows form and controls inside it need to be cleared.
Please guide on how to do this in C#?

Short version: Find the window and send it a message with
SendMessage.
Open up Spy++ and find your form's window. You will see that the window has children and they have classes of the form "WindowsForms10.EDIT.*" Those are TextBox controls. You can call things like SetWindowText to set the
text of the window to clear it.
To do this programmatically, you'll have to obtain the window hand that corresponds to the control. You can find windows with
FindWindowEx or
EnumWindows. Locate the window by name or class or whatever else you can determine about it. Find the child windows and "clear" them however you wish. I assume you mean to set empty strings to all the TextEdit controls. If you
intend to do something more sophisticated than that, then you'll have to be more specific about what you mean by "Clear all the data".
It may or may not be obvious that you'll be poking around with Win32 API calls via PInvoke to accomplish much of this. Example:
SetWindowText via PInvoke.

ADF: clearing all previous data in a page?

Hi Everyone,
im using Jdev 11G.
i have created 9 pages in ADF. i have used navigations to other pages through buttons from the first page.
all pages have data from different VOs.
Now the problem is : when i run the page for the first time it is working fine. but when i go back and run the page second time if data for some particular VO is not there (kept whereclause for VO in backing bean) then it should not display any data but it is displaying previous search data.
plz help to get out of this.
how to clear all the previous data while navigating to the page.
i have used VO.clearcache() methods also but didnt work.
Any ideas wil be really helpful.
Thank you.

Hi Desmukh,
Thanks for ur reply.
im executing the VO queries but if the parameters is not exists in the VO then it returns all the values in the VO.
i have used: vo.setWhereClause("EMP_ID=:empid AND EMP_NAME=:ename");
vo.defineNamedWhereClauseParam("empid ", emp_id1, null);
vo.defineNamedWhereClauseParam("ename",emp_name1, null);
vo.executeQuery();
here emp_id1 and emp_name1 are the values im passing to VO to filter VO.
if these two values doesnt match with any of the values in the VO then it returns allrecords from VO on the page.
Plz help.
Thank you.

How do I clear all personal data bookmarks history etc and import data from safari

I have a MacBookpro 10.6.8 and I am trying to clear ALL personal data on my new Firefox 12 (Bookmarks History etc) and then import all settings from my Safari. I've deleted the Firefox application as well as Library/application support/mozilla and Firefox still retains all of the old settings (Bookmarks History etc) from the old version 3
How do I do this.
Thanks

You can use this button to go to the Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Open Containing Folder
Make sure that Firefox is closed (Firefox > Quit Firefox) when you remove files in the profile folder.
You can also create a new profile.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile
You can transfer some files from the old profile to that new profile if you want to keep some data.

How to store jsp session data of different user in util.hashmap

how to store jsp session data of different user in java.util.hashmap
and access the data of all user on the server side
The same example is given in professional jsp but its not working.
I can use getIds() of httpsessioncontext but it's depricated

Hi
I'm trying to make an example.
With the following codes you can get the date from the session.
request.getSession().getAttribute("sessionname")
To store it in a hashmap you could do it like this ->
Hashmap hm = new Hashmap();
hm.put(Object key, request.getSession().getAttribute("sessionname"));
I hope you understand it if not just write it!

How do I access session data through an EJB?

Hi
How do I access session data through an EJB?
I am currantly developing a Web service (using ejb's, JBoss.net and Apache Axis). A client making a call to this Web service, is expecting a bussiness-object in return. My problem is that this bussiness-object i stored in a users session data. How do I retrieve this bussiness-object from the users session.
I have read that this does not work with httpsessions, is this true? If this is true, is it possible to store the bussiness object in a JavaBean e.g:
<jsp:useBean id="userContextWebImpl" scope="session" class="com.ac.march.client.UserContextWebImpl">
<%
String key = "test";
String value = "This is the value";
userContextWebImpl.setValue( key, value1 );
%>
</jsp:useBean>
and then retrieve this information through the EJB? Or is it possible to do this by using Statfull JavaBeans? Or can this be done through a nother solution?
Please help!

I have created a JavaBean with scope="application" to store some data. The data is stored when a user prefomes a spesific task.
A different person then makes a call to a Web-Service on the server. The Web-Service then asks an EJB to retrieve the data stored in the JavaBean (servlet cotext). In other words: How do I retrieve this data from the EJB?
I have tried with this code, but with no luck.
(ApplicationContextWebImpl is the JavaBean)
public static String getBookingResult( String key )
     String myResult = null;
     String myKey = key;
     ApplicationContextWebImpl applicationContextWebImpl = null;
     try
          applicationContextWebImpl = new ApplicationContextWebImpl();
          myResult = (String)applicationContextWebImpl.getValue( key );
     catch ( java.rmi.RemoteException e )
     return myResult;
}

Clearing all historical data from the graphs

Hi all,
Now that I have upgraded to 4.1.1c I want to clear all historical data and start from scratch with the graphs/stats/reporting. Is there a way to do such a thing? Could not find anything in the docs other than "clear statistics all" which seems unrelated.
Thanks
Adrian

Enclosed is the report montioring and configuring guide.
The clear statistics command clears all statistical counters from the parameters given. Use this command to monitor fresh statistical data for some or all features without losing cached objects or configurations.

Hi,
In BI 7.0 you wont find PSA tab in RSA1 (data warehousing workbench), for that you need to use RSA1OLD tcode.
Other way is to go to the datasource and then right click->manage there you can find option to check all PSA requests which were staged from that datasource.
