Dear all,

I have searched for any existing discussions with suggestions and solutions but couldn't find a suitable one!

I have a form with a container. Inside the container I have an image control. I used 'Isometric' in the Stretch method and it shows in the image control as follows:

As you can see, it's a bill output from a slip printer, length is much more than width.
What would be the best way to add a feature that the image is filled in the image control horizontally (ie full width) and I can scroll vertically to see the hidden part of the image?

Mike,

The only concern is with the 'Modal/Modeless' I think.
Let me check.



Rajesh
 
Rajesh,

why would modality be a concern?

Your main form is full screen, isn't it? Why do you need that to be modal at all? It should be a top level form and then it can't even be modal anyway. So the scrollable region done with a form positioned on your main form shouldn't be a problem. If it is, you just should fix your main form to be non modal, because it shouldn't be modal anyway.

Chriss,

Yes, Chriss (Mike too).
I was thinking that way. My main screen is not modal and so I can use mike's idea I think.
Anyway, I am checking other options as well as given by mJindrova.

Martina, I noticed one of the sites you linked to was a mirror of Carlos Alloatti's Ctrl32. Thanks for that. When the original site closed down, I thought that the class library was lost. I'm pleased to see that it is still available.

Hey, guys, Carlo´s GitHub, I look him, and don´t have Scrollbar and others (TDI), but I have all of them.
 
Hi Martina,

I am trying to use one of these.

1. The 2nd link has a well explained content but I do not see any link to download the files, VCX etc !!!

2. I tried to use the ViewPort (I assume it's your own product!). I was able to incorporate it to my own form. But I have problems with the sizing of the container. In my form's INIT, I have resized, repositioned the _vp_viewport. But, when I run, it resizes to the edges of my form. Please see below pics for a visualisation.

My generalised form:

When I run it, the viewport overlaps my "Close" button by filling the height upto the bottom of my form!

I see properties like, "nSizeDeltaRight", "nSizeDeltaBottom", "minleft", "mintop", "maxHeight", "maxWidth" etc. I played with it after comparing and assuming its purposes but not yet got it to work properly the way I need.

Do you have a document, explaining the correct use of these properties?



Rajesh
 
Rajesh,

Please, can you upload your form (must be run able)?



mJindrova
 
Chriss,

Thanks. I downloaded and tried the SContainer and it's working!
However, there is a left and top border line appearing with the image even though I have set the borderStyle to none for the Image control (see pic). Need to check that.

Also, as you had mentioned a few days back, I will have to check the scenario where there are multiple pages in the report output.



Rajesh
 
Mike,

I got it working.
The ctl32 download set has almost the same documentation for S-Container.
Thanks



Rajesh
 
Martina,


I think, I will have to modify many places and hard code many values in order to make it runnable.
Let me check. Will let you know.

You're thinking this has to come from tl32, but I see borders in the screenshot you initially posted. A line can have many sources, a container has a border, you could have a line in the image itself..., you should find that out yourself. In the sample form I don't see a line generated, the scrollbars are slightly off an ideal position, but that's a different problem.
