\"Hey, \n

Hey, Scripting Guy! In your HTA examples, you show us how you can click a button and cause a single subroutine to run. How can I add two or more subroutines to the onClick parameter for a button?

Hey, FM. You know, there\u2019s an interesting branch of cognitive psychology known as problem finding<\/I>; the idea is that your ability to answer a question often hinges on how you ask the question in the first place. For example, you – and several others – want to know how to specify multiple subroutines in the onClick parameter of a button. We\u2019ve seen people try several variations like this:<\/P>

<input type=”button” value=”Run Button” onClick=”Script_1; Script_2; Script_3″>\n<\/PRE>\n
As you\u2019ve discovered, that doesn\u2019t work.<\/P>\n
So let\u2019s put our problem-finding skills to the test and see if we can rephrase this question. (Typically the Scripting Guys don\u2019t need to find problems; problems have a way of finding us<\/I>.) Here\u2019s the crux of the matter: do we really want to add multiple subroutines to the onClick parameter, or do we just want multiple subroutines to run any time we click the button?<\/P>\n
If it\u2019s the latter, then we have an answer for you:<\/P>
<html>\n<head>\n<title>Multiple Subroutines<\/title><\/p>\n
<HTA:APPLICATION \n     ID=”objHTAHelpomatic”\n     APPLICATIONNAME=”MultipleSubroutines”\n     SCROLL=”yes”\n     SINGLEINSTANCE=”yes”\n     WINDOWSTATE=”maximize”\n>\n<\/head><\/p>\n
<SCRIPT Language=”VBScript”><\/p>\n
Sub RunScripts\n    Script_1\n    Script_2\n    Script_3\nEnd Sub<\/p>\n
Sub Script_1\n    Msgbox “This is subroutine 1.”\nEnd Sub<\/p>\n
Sub Script_2\n    Msgbox “This is subroutine 2.”\nEnd Sub<\/p>\n
Sub Script_3\n    Msgbox “This is subroutine 3.”\nEnd Sub<\/p>\n
<\/SCRIPT><\/p>\n
<body>\n    <input type=”button” value=”Run Button” onClick=”RunScripts”>\n<\/body>\n<\/html>\n<\/PRE>\n\n<\/THEAD>\n\n\n
\n
Note<\/B>. The preceding code is designed to be run from an HTA, an HTML Application<\/B><\/A>. If you want to test the code, just copy the script, paste it into Notepad or some other text editor, and save the file using a .HTA file extension.<\/P><\/TD><\/TR><\/TBODY><\/TABLE>\n
<\/DIV>\n
If you glance through the code you might notice the HTML tag for the button:<\/P>
<input type=”button” value=”Run Button” onClick=”RunScripts”>\n<\/PRE>\n
As you can see, we specify only a single subroutine (RunScripts) in the onClick parameter. Ah, but take a look at the code for the subroutine RunScripts:<\/P>
Sub RunScripts\n    Script_1\n    Script_2\n    Script_3\nEnd Sub\n<\/PRE>\n
There\u2019s your answer right there. All we do inside this subroutine is call three other subroutines: Script_1, Script_2, and Script_3. That\u2019s how we can run multiple subroutines from a single button click: we don\u2019t put all those subroutines into the onClick parameter, we put them all into the single subroutine called by onClick.<\/P>\n
In other words, problem-finding – and cognitive psychology – to the rescue. And to think people told us that graduate school was a huge waste of time and money: at least we got a Hey, Scripting Guy!<\/I> column out of it!<\/P><\/p>\n","protected":false},"excerpt":{"rendered":"
