Rif.: set Picture

[estelle27]

Hello ! 

I want to set a picture on my uir but I don't know how to do it.. I have a button, when you click on it , a FileSelectPopup is appearing , we select an image and then i want the image to appear on my uir.

I wanted to do a SetCtrlAttribute with a Control Value but I don't see it ...

I also searched on the community but the web links just put me in the main page of the Manuel of Labwindows...

Use a picture control where to load your image.

But how can I load the Picture ?

Kind regards

This is a very general question that refers to CVI as a whole rather than the picture control.

When you have a controlon a panel you can right-click on it to display a context menu that in case of the picture control contains the elements included in this page: Picture Control Overview

From this meu you can navigate into CVI help to locate the informations you need: in this case open Programming with Picture Controls and you will see how to load an image into the control.

This applies to every object you can put on a panel and is a very useful feature that I myself continue to use after many years working with CVI.

Okay I see, I tried to do it with the DisplayImageFile but the program break and it says that the function return -95, it's "file access permission denied" I don't really know what that means.. my image is a .png file, i saw on an other question in this forum that the DisplayImageFunction can have a .png image

File access permission denied error has nothing to do with the picture control: it rather refers to the program being unable to access the file, either because it is locked by another program or because there is a problem in permissions to the file. Are you able to open the file e.g. in Paint when the program fails to do so?

Okay  and yes I'm able to open the image with Paint

I found the problem ! I had a Openfile that was opening the image , that's why I had the error !

Thanks a lot !
