I want to Resize frames on a button click

Try
<INPUT TYPE="button" VALUE="Viewer" onClick="parent.document.getElementById('theframe').cols='963,*'">
Give the frameset that you want to control an id="theframe"

thankx sooo much... it worked

FYI for others that may experience this problem... I found out that IE doesn't like setAttribute() to reset an existing attribute (or to set an attribute that IE defines by default (such as 'id'!). I had a similar problem when I was creating elements using DOM and trying to setAttribute('id', 'newIdName') and devised a work-around function to handle this situation:

function attributeSet(elem, attrb, setting)
{
var elemAttrb = elem.getAttributeNode(attrb);
if (elemAttrb)
{
elemAttrb.value=setting;
} else {
elem.setAttribute(attrb, setting);
}
}
