For my GUI i would like to have two pairs of buttons that scroll up and down a scrollarea. The first set of buttons should work on say scrollarea1 and the second set of buttons should work on a scrollarea2. The widgets that I put in the scrollarea are called viewport1 and viewport2. Since both both set of buttons should do the same (scrolling up and down) I thought I would make two slots called scrollUp and scrollDown that would handle the scrolling for both sets of buttons. Unfortunately I cannot make this work and need some help. I have tried the following: QPushButton up; QPushButton down;

I want to check some condition when a particular button is clicked how to do this? $(document).ready(function () { var prm = Sys.WebForms.PageRequestManager.getInstance(); prm.add_initializeRequest(InitializeRequest); prm.add_endRequest(EndRequest); Search("Other"); }); function InitializeRequest(sender, args) { } function EndRequest(sender, args) { alert(sender._postBackSettings.sourceElement.id) var str1 = new String(sender._postBackSettings.sourceElement.id); if (sender._postBackSettings.sourceElement.id == ContentPlaceHolder1_btnNew) { alert("You have clicked new") Search("NEW"); } else {

In Delphi, sometimes we need to do this... function TForm1.EDIT_Click(Sender: TObject); begin (Sender As TEdit).Text := ''; end; ...but sometimes we need to repeat the function with other object class like... function TForm1.COMBOBOX_Click(Sender: TObject); begin (Sender As TComboBox).Text := ''; end; ...because the operator As does not accept flexibility. It must know the class in order to allow the .Text that come after the () . Sometimes the code gets full of similar functions and procedures because we need to do the same thing with similar visual controls that we can't specify. This is

I'm sending mail from Jenkins to an anonymous SMTP relay internally. That relay then securely sends mail to exchange online via TLS on port 587. The transport works perfectly, the issue is that Microsoft requires the Sender address match the authentication credentials login name which is the same as the account email address. For example sake, say this is foo@mycompany.com. How can I make jenkins always send mail from foo@mycompany.com? BTW when I say the transport works perfectly what I mean specifically is that I can drop a formatted e-mail file into the "Pickup" directory on the SMTP relay

I have a form that loads from a click of any of three buttons (Add, Modify or Delete). When the form loads there is a 'Confirm' button which will perform a task depending on which button was originally used to show the form. Is there an easy way to determine which button was originally clicked so that the right code can be executed? Thanks Well suppose to define at the global level an enum like this Public Enum CommandAction Create Modify Delete End Enum Now in the code used to launch your second form to execute the Add command, you could write code like this (of course you repeat the same but
