HTML.TDC – Giga thoughts …

This post includes some basic tips to consider while building a HTA/HTML application. Clearly I am no Web guru knowledgeable of the various technologies that make the Web zip and zing. Here are my 2 cents

Any HTML page will contain tags for e.g

etc.

Any self-respecting Web page will include a vertical or a horizontal menu. For this you would need to use a Cascade Style Sheet (CSS). Rather than re-inventing the wheel do re-use the cool menu items & CSS style sheets at the following site http://www.dynamicdrive.com/style/layouts/

You will also be adding textboxes, radio buttons, submit and reset buttons. Assuming you have all the form controls in a single form you need to use the following

Consider a form

Enter the file name containing the server list (srvr_list.txt) :

For this to get the input from the text box use

file = form1.servers.value

Using a radio button is a little tricky. Radio buttons belong to a group and the way to handle this in VBscript is as follows
Include subdirectories Yes

No
This is done by iterating through the radio button list

for each radio in form1.Radio1

If radio.checked = true Then

If radio.value = “Yes” then

objInputFormat.recurse = -1

ElseIf radio.value = “No” Then

objInputFormat.recurse = 0

End If

End if

Handling a Submit requires that you handle the onClick action as below

This indicates that when you click the Submit button you will invoke the subroutine fileSize

A Reset button is of type “reset”. As long as you enclose all the controls in a single form hitting the reset button will clear all the controls.

Populating output in a table: To populate output dynamically in a table I used MS Tabular Data Control (TDC) when the output is written to a CSV file. The cool thing about this is that it automatically paginates output and display “n” entries per page instantaneously. I had tried various thing like populating using DOM, InnerHTML but all of those failed miserably when the o/p was very large. With TDC I can display ~30K entries instantaneously from a CSV file.

This is done as below

The CLASSID is the TDC control. Make sure you choose the correct delimiters and text qualifiers. Populate your CSV file.

You then need to connect this with Datasrc as below
