LabVIEW DLLs based on VIs using popup message windows

[boucan_canot974]

Hello,

I built a DLL based on a VI under LabVIEW 6.1.
This VI is using a popup message window. When I am using the DLL in a VI (calling the function exported by the dll), the labVIEW VI is freezing. When I debug the VI, it appears that the popup message is blocking the application.
I am not seeing the popup message either.
You will find a code example linked with this message.

Does someone has an idea to resolve this problem?

Regards Pascal.

I experienced that same behavior too. The problem is with LabVIEW's Dialog box (Functions palette -> Time & Dialog).

You can solve that by creating your own dialog box instead. Just make sure you change the option in application builder to keep the front panel.

Hello,
I tried this solution too ... but it is the same problem. May be I am not using the good options to build my dialog box.
Have you got an example?

I have also the same problem, with the "Open VI reference" property!!! it's blocking itself!
Is there a solution for this too?

In my website, I have an example that includes a Dialog Box for a .dll. You can obtain it from here:

The example is VIs for DeployMaster. Probably you can modify the Dialog VI for your use.

I just wanted to add a quick comment. If you go to create a pop-up VI of your own, you need to make sure that when you build the dll that you include the front panel.
