Draw External Control
This download shows how you can draw an external control directly in a Navision form.

Don't forget to compile the project first to create and register the DLL. Then use the form 88000 to see the result. This is a raw and simple project. There's a lot of improvement a skilled c++ developer can accomplish.

Contains:

1- Project .Net C++ (open the project and compile to create and register the dll!!!)
2- Navision form with a reference to the dll

Sorry for the lack of documentation but didn't had the time to do it.
Hope someone can create some nice things and share with the mibuso community.

A great year to everyone.

e:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxv_w32.h(18): fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>

What is the problem?

That error, and a lot more , apeared to me also and i had to deal with them. I dont have the answer right away, but when i have some time, maybe in the weekend, i will try to create a project from scratch and document all my steps and all error solutions. It was a hard fight for me the first time i did it.

Haven't tried it yet, but cool that you post the code on the internet.

Draw External VISUAL(!) control?

Does it works in Navision <= 3.70.B.

Regards

it should work with all versions

I should work or it working?

Have not tryed it yet so i dont know

Bump.

So, anyone got this built? Anyone knows what exactly is happening in the code, could it be done in other than .net?

I've tried in other languages but got no results.

You have to understand and know c++ to compile or change this project, there are no miracles.

Yes, possible. In VB6.

I couldn't build the above example, but I managed to make it from scratch (with lots of googling and learning a bit C++ . I started a new atl project (vs2005), added a simple object class and implemented a slightly modified version of your your code. It works quite nice and it can host all sorts of controls (even browser).

Now, I would like to implement the code to respond to resize events. Normaly the external control wouldn't resize. I can call the function to update the window size from Navi, but that's not really it. Any ideas or suggestions in which direction to look?

Thanks.

To allow resizing you have to override default control's 'WndProc' (subclassing).

Care to explain that a bit more? By default control you mean my atl object or the hosted control? I can't find any WndProc methods in those. Then again, this is my first time c experience, so I apologize if i ask stupid questions.

Each normal(!) visual control in Windows has own "window procedure" to receive different kind of messages from OS. You have to receive this messages (WM_SIZE at least) and resize your control to fit available "client bounds".

I'm not a C programmer. In VB6/VB.NET/C# it's pretty easy.
