Change textbox text at runtime

[pkonduru]

Hi All,

I have a custom dialog I created using NSD from the Coolsoft NSIS designer.
I have a check box on the Dialog with some standard string say "Check this".
I am trying to change the Value of this during runtime. The code from the dialog designer is below:

; === CheckBox1 (type: Checkbox) ===
${NSD_CreateCheckbox} 50.03u 73.23u 110.58u 14.77u "Check This"
Pop $hCtl_ExistingHub_CheckBox1

If I do this in my installer, it doesnt change the text:

${NSD_SetText} $hCtl_ExistingHub_CheckBox1 "Check that"
I tried putting this line before calling the function that shows the page.

Any inputs?
