Yes, I tried picture Ring ,but the issue is that the items(images) are changed one by one and i couldn't make it like what it is shown in attached image ( all images are visible and user can select one among them)

You were probably clicking the increment/decrement (up/down) arrows for the ring control. Just try clicking on the picture itself. You will get a thumbnail of each picture and you can select the one you want.

If you're expecting it to look like the picture you posted, i think you'll be disappointed. If you want that, you'll have to do a bit more work with either a picture control (not picture ring) or an XControl. If you're on Windows, you might also be able to find an ActiveX or .Net control that would work.

Thanks Scott. yes by clicking on the every picture it shows all pictures in very small scale and in hozizental direction which is quite different from what i need.

Also do you know why it is not possible to change numeric indicator's size VERTICALLY? It only could be resized horizentally!!!

May be XControl is a good way to realize it.

I have a feeling that what you are trying to do is more advanced than what your experience can handle. However, this is how we all learn right?

An XControl won't help you. An XControl is just a nice package. You still have to figure out how to do what you want. Once you figure that out, you can then create an XControl out of it if you want, but not necessary.

I could probably implement what you want in pure LabVIEW using 2 picture controls and some other tricks, so it's definitely doable. But it's not something you can do in 5 minutes.

I suggest you study up on picture controls.

Another consideration is that you might want to change your design. You can probably use an array of picture controls which allows you to scroll through the images. Then when you hover over the one image you can overlay another array of images slightly shifted to the right.

Many creative ways to do this but not easy.

The problem is we are pretty much stuck with the controls we are given. As we don't have access to the control canvas and the "OnRedraw" event, we cannot change the control (with the exception of a few cosmetics). Everything we do to get around it is really a kludge and not for the faint of heart.

You are probably better off finding an Active X or .NET control tat supports images and using that.

This won't do the cascading effect, but you can have a quick look at how you could use a simple array of pictures with events to act as a drop-down picture ring.

Thanks francois, but when i run it and browse to select the directory in which images are, it doesn't select!!

Select the directory before running the VI.

You can check on startup (init frame) and add a browse for directory primitive from the File IO palette.

I tried again but still when i browse to select a directory which contains my pictures,either in non-executing mode and executing mode! it does not select the directory. could u double check the file yo sent me? Thanks

Did you have any PNG files in the directory? You can change it in the code if you use other formats. Also, I've limited it to the four first file in the folder for the demo, but you can change that in the code.

I've changed the code to ask for the folder on startup.

Yes I have png files. I tried the new file you just sent. again the same problem. As you see in the image, when i select the folder which contains png files nothing is selected in "file name" section. it doesn't select neither by selecting and hiting open button nor by double click or etc.!!!

Browse to the folder that contains a list of your images (the usual double-clicks to open the folder). When you see the png files listed, select "Current Folder" at the bottom right.

Froncois!Thank you so much for your kind effort. I did exatly what you showed in video. Now it shows this error message after selecting "current folder". I don't know what is wrong!!!!

It didn't show up any error,,

As I thought... if PNG's are actually not corrupted.

Let's try something else:

Can you check where the error is occuring in the code?

It works fine in my place, so we've got to find the point where the error is generated. Use execution highlighting.
