Export a pageLayout to PDF in ArcObjects

JMJJDJM

Hi

We are migrating an application in 9.2 to version 10.
The following VB code. NET converted to PDF in version 9.2 but returns a blank page used in Arcgis 10.

Anyone know how to export to PDF the active layout (SDK. NET ArcGis 10)?

Thanks in advance (JMJ98)

I don't have a solution for export from .NET aplication to PDF.
VBA runs but the same code from my VB .NET application fails and returns a blank PDF. I think that error have a difficult solution ....

Maybe its the moment of on arcpy thinking, and see if runs.

Send me your vb.net code...

JMJJDJM

I've not had a chance to step through the code yet but wanted to at least mention that the ArcPy site package has simple functions to export to pdf. We have documentation in the SDK regarding calling python scripts from .NET if this sounds like an alternative you may be interested in.

Somehow you have to play with focus pagelayout... not basically activeview...

I tried to pass the PageLayout, but I have not worked.

In the attached image, you can see that the variables contain values (Debugger VS2008), but values should not be correct, because the PDF is generated blank

Thanks for your help.

Hi (sorry for my english)

From an application in VB.NET and try to open an ArcMap print your layout. (Automation)

We have included the sample code (ExportActiveView) and get a blank PDF.

In contrast, using the same example with ArcMap works perfectly.

What do you mean by "if runs in a windows form application (with automated arcgis opened)"..Please can be clear on the same...or any screen ?

This sample runs me ok, inside ArcGis 10.
But if runs in a windows form application (with automated arcgis opened), the result its blank PDF.
