Hey tstanley -
CVI doesn't offer an API to create one of these balloon popups. However, most other tray icon tasks can be accomplished with functions in the Programmers toolbox. There is a great example that demonstrates these functions named Trayicon.
To create the balloon popup you are talking about, you are either going to have to manage the tray icon API by yourself, or make some modifications to the toolbox.c source code, because some of the necessary manager functions are not exported. Using this as a reference, I added a couple lines of code to toolbox.c (without any error checking for the sake of clarity) to display a very simple balloon popup. Let me know if you have any questions.
int CVIFUNC ShowTrayIconBalloonPopup (int huser)
{
BOOL sdkRetVal;
SYS_TRAY_ICON *ptrayIcon;
ptrayIcon = TrayMgrGetIconFromHandle (huser, NULL);
ptrayIcon->nid.uFlags |= NIF_INFO;
// szInfo is a 256 byte buffer snprintf (ptrayIcon->nid.szInfo, 256, "This is a test of a balloon popup.");
ptrayIcon->nid.uTimeout = 5000;
S_Shell_NotifyIcon (NIM_MODIFY, &(ptrayIcon->nid), &sdkRetVal);
return 0;
}
