GDPicture.NET - New Installation problem
GDPicture.NET - New Installation problem
Downloaded and installed GDPicture.NET V6.6.05
Using Visual Studio 2008, opened an existing application where I want to add the GDViewer.
Following the "Using GdPicture.NET" section of the documentation I added a reference to GdPicture.NET
Select Project / Add Reference...
Select the Browse tab and select the GdPicture.NET dll library which can be found on C:\Program Files\GdPicture.NET\Redist\Framework X.X\GdPicture.NET.dll
Add a link to the GdPicture namespace where you want to use the DLL
In C#, add the appropriate using directive to the code file(s) where you want to use the DLL: using GdPicture;
In VB.NET, add the appropriate Imports directive to the code file(s) where you want to use the DLL: Imports GdPicture
Then I followed these instructions:
4. Using a GdViewer object into your application.
Before starting, make sure you successfully done first & second steps.
The GdViewer class is a visual class. Therefore you can instantiate a GdViewer object by code or simply dragging a GdViewer item from the Visual Studio Toolbox to your Windows Form:
Right-click into the Toolbox Items and select "Add/Remove Items" for visual studio 2003 or "Choose Items" for Visual Studio 2005 and Visual Studio 2008.
Select the .NET Framework Components tab
Click on the Brows... button
Select the GdPicture.NET dll which can be found on C:\Program Files\GdPicture.NET\Redist\Framework X.X\GdPicture.NET.dll
Now you will be able to select a GdViewer Item from the Toolbox in order to draw it within your forms.
The problem I'm having is that the GdViewer Icon/description in the Toolbox is grayed out. I cannot select it to drag it onto my webform.
Please advise...

Hi,
GdViewer is a Winform control. You can't use a Winform control in a Webform.

Oh, too bad
It wasn't clear from the docs that this was winform only especially since your sample asp.net demo (pdf-ocr) includes it...

Re: GDPicture.NET - New Installation problem
You can use it in server side only (as demonstrated in the asp.net sample).
For client side you need native webcontrols.
