I am using this to show a report i generate, the report is HTML saved as a local file.

i want the default page to load when i create the element. ie a user clicks generate report

a child window pops up with the browser that is pointed to "report.html"

should that work or do i need to incorporate a HTTP server also into this?

That should work just fine.

I tried your code, and I found that the browser element needs the full path of the URL.
In your example, it looks like as if report.htm is located in the directory above the directory of the browser program.

If the URL is set by the user, e.g. during installation, you can use the @curdir() function to retrieve the path and cut off the last part of the path by string manipulation.

Good luck.

Yup, pretty sure Claz has it. It needs full path and may also require you to put in a full URL too, such as "file://c:\somedirhere\report.htm".

awsome thanks guys the @curdir()\report.html worked.

also can you print a graph element, like in excel. what i would like to do is

have a graph generated off the selected data and then save the graph and a png to use on the report.html. or can i add it as a layer over the browser element and print?

One thing 's for sure: VDS cannot cope with the png format; I've been searching for any VDS app or dll able to use png, but could not find any.
It's a pity, because png is a great format for any raster format not being photos.

The easiest thing to do is to write the graph to a bmp (I know, I know it's very big) or convert it afterwards to a jpg file.

If you need to create the graphs by yourself before (which I assume), it might be a good idea to use the bitmap commands for that. I've been using it a few times and it works great. Save it as a bmp, use vdsconv.dll from PGWARE (2003) to convert the bmp to gif or jpg, and delete the bmp afterwards. Job done and still a small file...

I hope this answers your question.

I now see it does not answer your question at all. Embarassed

I'm not very familiar with using layers in html, but I hope somebody else does.

Sorry

the VDS element. i want to save the element as a image

Do you mean the Piechart element?

Aslan is right: the Image element of VDS can show png's.

But that's only a viewer element: you're not able to use it to save any graphical data with it.

And my question remains: how do you create the graph? With piechart, with shapes?

Aslan · Posted: Thu Feb 03, 2011 3:28 am Post subject:

I would recommend using a browser based graph or pie chart and just use the browser element which will also allow you to print.
