Can I add controls at runtime in JApplet

Please also tell me what good is JApplet for. As I cannot interact with database and there are several other limitations. Should I go and use JApplet in my application or avoid using them.
My basic question remains the same "Can I add controls at runtime in JApplet"

Yes, you can add controls to an applet at runtime.
Applets are run on remote computers, in browsers for instance.
Since they are run remotely, connecting to a database can be difficult. In most cases you'll need a server that makes the connection with the database. The applet speaks with the server via a socket.
If you're writing a standard desktop application, then you should use JFrame.

  • Legacy VB6 project. Can no longer add controls to the form.

    Working on a VB6 project that has been in continuous use since 2002.  Needed to make a simple mod and add a new control.  Choosing any control and attempting to drag it on to the form always fails with a black circle with diagonal bar at the cursor
    as soon as the cursor leaves the toolbox.
    Reloaded VB6 and SP6. No luck.
    Tried a new "Hello World" project but was unable to move any controls from toolbox.
    Now the weird part.  Went to 4 other old computers that have always worked in the past.  All of them failed the "Hello World" test as well.
    This is perfectly legal Microsoft Visual Studio Professional load from one of our old MSDN disks.  Are these timebombed or something?
    The program can be edited, compiled and run with no issues, I just can't add controls to any form.

    Hi

  • How can I add an image to a project and change it at runtime?

    I'm using JBuilder6 and I thought I saw a control to add images but I can't find it. I also wanted to be able to change the control at runtime. Also how should I specify the path so it knows how to use it? I hate to hard code one in. Since this is probably gonna be ported to other OS does Java have a way around this? I was going to put the images into my project's directory. For me to be able to just include the file w/the extension do I need to put it in the src folder or will the main directory be accessible?

    To add an image, or other source file with JBuilder, you have a button call "Add to project", his icon is a folder with a green cross.
    To call the Image os independant, I sugest you to put your images in a folder "image" in your project folder. Then to call them, you could use this :
    image=new ImageIcon(AClass.class.getResource("image"+java.io.File.separator+imageName));Where AClass is a class of your project, in general, the class where you call getRessource;
    "image" is the name of the under folder where are the image in your project folder;
    imageName is a string with the name of the file witch contains the image, for exemple : "my image.gif"I hope I help you.
    JHelp.

  • How can we add a control on our .jsp webpage for uploading several image fi

    How can we add a control on our .jsp webpage for uploading several image files as done in gmail attachment, Where a Remove button also appears if we wanna remove the particular attachment.

    The SCOM Management Server is in Domain A.  I've tried it already and it has failed.  
    So just to clarify the method I used was to go to Administration>Security>User Roles.  Then New User Role>Read-Only Operator.  In the Create User Role Wizard I then gave the User Role a name, Clicked "Add" under User Role Members.
     Then the Select Users or Groups window pops up and I changed the Locations from Domain A to Domain B and searched for the user, which it's able to find, then clicked "OK" to add it to the User Role members which it does just fine.  On
    the next page which is Group Scope I checked the one group I want this account to have access to and then click next.  This brings me to Dashboards and Views where I click the radio button for "Only the dashboards and views selected in each tab are
    approved" and chose the folder of dashboards I want this account to access and then click next.  This brings me to the Summary and I click "Create".  At this point it thinks for a moment then closes out the wizard but the new Read-Only
    Operator does not appear.  I then look in Event Viewer and see the Event I pasted above.
    Am I doing something wrong here?  Any guidance on how to get around this issue would be much appreciated.
    Thanks,
    Jake

  • Can't Add To Access Control List Airport Express

    We have both Airport Extreme (2) and Express Base Stations (3) to create a wireless network. On the Extremes I can click the Add button in Access Control in the Airport Admin Utility to add people to the list. On all the Express Base Staions I can edit or delete entries already on the list but can't add any new ones. I can export an Access Control List but not import one. The button is greyed out only the button works. I could add to the lists in the past and I'm not sure when it stopped working. The network structure and settings have not changed. Has anyone heard of this problem?
    Aiport Express   Mac OS X (10.4.8)  

    WDS is used on two Express units to relay the signal from the main base station but not on third one which is connected directly to the network via ethernet.
    On the internet connected Express the Airport Network setting is:
    Wireless Mode: Create a Wireless Network (Home Router)
    All base stations have the same name to allow roaming.
    Internet is connected using Ethernet.

  • Can I add Containers and controls to UIComponent

    Hey,
    Can I add Containers/controls to UIComponent Class? If so what is the use of separate Canvas container Class (when UIComponent itself is holding all the container objects)?
    I tried to add 'Canvas' object to UIComponent Class, it is working...
    Can anyone clarify my question? please
    Thanks,
    Praveen

    Containers expect children to be IUIComponents and have built in logic for
    scrollbars.
    UIComponent children can be anything and doesn't have built in logic for
    scrollbars.

  • How can I add logic control with timeout in OSB?

    In the proxy service, when I try to call business service, the business service may timeout, how can I add logic with this? Like, I can set the timeout to 20 seconds, if more than 20 seconds, then do something else. But I just want this service can set to 20 seconds, others may different. Is that possible? Thanks.

    There is a Read Timeout and Connection Timeout setting in the Business service configuration.

    Test and let us know if it works.

  • How can I approach controls in Dialogbar?

    I would like to know how I can approach my controls in Dialogbar?
    I made an dialogbar in mainframe and added some NI Controls and normal controls (ex, CEdit). I can handle normal controls without problem, but if I try to handle NI Controls it gives runtime errors.
    Does it happens since Ni Controls are ActiveX controls? In that case, how can I handle them?
    I tried like follows:
    CNiNumEdit *numEdit;
    numEdit = (CNiNumEdit*)m_wndDialogBar.GetDlgItem(IDC_CWNETL);
    numEdit->Value = 10;

    Simply go to the "project->Add to Project->Components and Controls" Select the NI controls you want to use. You will see a bunch of new classes added to you project in your class view.
    See zip file for simple demo....
