Re: powerpoint problem

Please use code tags to show your code : see Writeup Formatting Tips
Update: O.P has since done this. Thanks.
Please use strict; - that would have pointed out your error (below)
$Slide is different from $slide. In your code, $Slide is not defined.

FYI, your "while ($i < 5)" loop can be written more idiomatically thus:

for (my $i = 1; $i < 5; $i++) {
        $slide = $ppt->Slides->Add($i, ppLayoutBlank);
    }

I think that loop would be even more clear this way: `foreach my $i ( 1 .. 4 ) { $slide = $ppt->Slides->Add($i, ppLayoutBlank); }` [download]	[reply] [d/l]

Agreed. (++) To take it to the next step, how about: `$slide = $ppt->Slides->Add($_, ppLayoutBlank) for 1..4;` [download] and avoid the (explicit) pesky temporary variable. However, for newbies, I'd suggest they stay with my original "C-style for loop" suggestion (to use when they actually need the index variable), until they get more comfortable with perl-style use of $_ for temp vars, and lists generated by the ".." operator.

I find that with a long statement like that, the modifier gets lost. A casual peruser might not notice there's a loop there at all. It's a little better if the modifier gets its own line like so: `$slide = $ppt->Slides->Add($_, ppLayoutBlank) for 1..4;` [download] I like temporary variables too. Usually when `$_` appears, it's a comprehension vortex. In this case, the variable (`$i`) is not much better, but sometimes a good name on a variable can add a lot of documentation. For example, `foreach my $good_guy ( @ARGV ) { push @my_attr, get_attributes( $good_guy ); }` [download]	[reply] [d/l] [select]

my problem is not wid the loop, I just sent a part of my code. The main problem is I couldnt paste the ".gif" file in my PPT slide. `$pname = 'C:\Documents and Settings\Desktop\Perl_files\file.gif'; $slide->Shapes->AddOLEObject({Left=>225, Top=>125, Width=>480, Height=>320, FileName=>$pname});` [download] It is just pasting a text "file.gif" instead of picture. So is there any way I can import the picture..??	[reply] [d/l]

In addition to pc88mxer's advice below, you need to use the AddPicture method (instead of AddOLEObject) to add a picture from a file. Thank you for using <code> tags. Perhaps you could edit your original node, and add those, to assist new readers of this thread. "How many times do I have to tell you again and again .. not to be repetitive?"	[reply]
