Hey there guys.

I have a strange problem with a report of mine.

Basics:
UnitOfMeasure is cm (i'm from germany)
Paperkind is A4
Landscape is false
Margins are set to 10mm each side
Got some normal datafields from a dataset and a picturebox
The items are filled as they should.
Picturebox is set to ScaleProportional

Issue:
I want my report with 2 columns.
Its an labeled report and the bounds, margins, paddings and so on are as set as the 2 cloumns will fit on the document.
The designer is showing me the second column but if i run the report in my application, the second column will not appear.
The first column is as long as the whole document (it looks like streched).

I've tried various settings on the meassures but nothing will work.

Hopefully some of you has an idea how to fix my issue.

Regards, Tom

[UPDATE]
The problem occurs only if the picturebox value is set by the following code:
this.pictureBox1.Value = "= snvMain.GlobalParams.getImageToArticle(Fields.artnr)";
The function called returns the ImagePath as string.
Reportviewer even loads the image in the Picturebox and later its getting an GDI+ error too.

Slowly but sure it drives me to despair :/

Hi Thomas,

As outlined in the Creating Multi-Column Reports help article, in non page oriented formats like HTML one-column reports are supported only. Also multi-column report used in subreport item would be rendered as one-column report as well.

Hi Steve.

Thanks for your reply.

I created a new report similar to the one i talked about.
There i have NO issues...

Seems like some wierd code was generated...

Anyway, the new one works well. Just a Common GDI+ Error drives me a little bit mad....
Is there a way to get the InnerException?

I've googled about the error and where i looked, the Forums told me, to watch the Inner Exception.

Thanks in advance, Tom

[UPDATE]
I just figured out, where the GDI+ exception is thrown:
An error has occured while rendering the report: System.Runtime.InteropServices.ExternalException: Allgemeiner Fehler in GDI+.

This is the trown exception.
The "Allgemeiner Fehler in GDI+" is the well known error "A generic error occurred in GDI "

Any workaround about that?
Maybe i should say, i'm trying to load about 400 Images from FileSystem, not Database as like in your Demos

Hi Thomas,

Your initial description of the problem led us think that you're using web site application, since the one column is specific to the HTML rendering extension.
This is a pretty generic error which as you can see is not really descriptive. As you have found out there are numerous articles on this error, but it is thrown for completely different problems and one cannot easily identify the culprit.
What should be taken into consideration in your case is how many MBs are these 400 images that you load, as they would be loaded in the worker process and as you know it would be recycled around 1400 Mb. Try decreasing the number of images and their sizes and you should not experience such problems.
