Well, i would actually use it for all the functions (byte, bool, float etc), as it handles
even #VT_BYREF etc, which your code currently cannot handle.

@freak

I hope mk-soft will change this in next time, thanks for support

Update
DispHelper_Include.pb

added OCX_CreateGadget with Unicode-Support (PB-Source)
I hope it works like the lib.

Updated the VariantHelper_Include.pb

Anyone know of good sites (with safe stuff) that list useful and usable ocx etc files?

I want to try my hand at something (anything) from scratch, but best if it is useful just in case against all odds I get it right.

thanks michael, i have uploaded your new version.

HI Ts-Soft
I make what you say to me and i have always the same problem

Type Mismatch "LoadcomponentFromurl.argument.index:3

The problem seems to come from the third argument of the function
@"private:factory/swriter", @"_blank",1 ,openpar
Openpar is an array :
openpar(0)=#True
openpar(1)="secret"
openpar(2)=#True

These function works well in vb.

A array in com is a VARIANT-Type! Not the same as an array in PB

Posted: **Tue May 01, 2007 7:44 pm**

ts-soft wrote:A array in com is a VARIANT-Type! Not the same as an array in PB

ok BUT HOW CAN I DO TO HAVE THESE INSTRUCT WORKING it seems that the problem come from the third parameter :
dhGetValue("%o",@oDoc, oDesk,".loadComponentFromURL(%T,%T,%d,%T)",@"private:factory/swriter", @"_blank",0 ,openpar() )
of loadcomponenturl. the 0
Maybe if you can't help me i will renonce to igrate my programm becase i am unable to solve this problem.

Change the code to none use of array

ts-soft wrote:Change the code to none use of array

It's impossible because Office org need an array with this parameters but the problem do't comes from the array it's come from the third parameter the 0 which seems not passing

Posted: **Wed May 02, 2007 2:26 pm**

You can only pass strings and longs, or you use an variant. PB can't pass an
array to this lib in this form!!!.
Office org need an array is nonsense. Put all Values, one by one, and call Method.
