I am launching some exe using LaunchAppandWait function. During this process i just display a message "Please Wait". But, I want the user to know the progress of it by displaying a progress bar.I have given LAAW_OPTION_USE_CALLBACK in option parameter in LaunchAppandWait. I have added some code in OnLaunchAppandWaitCallBack function for updating the progress bar every time it is called. But, the progress bar is not getting updated. When will the function OnLaunchAppandWaitCallBack be called?
I am using Installscript project. I use Setstatuswindow for updating the progress bar in OnLaunchAppandWaitCallBack function. I am setting the interval as 1second.In such case, the OnLaunchAppandWaitCallBack function should be called every 1 second the LaunchAppandWait waits for the application to launch and the progress bar should get updated respectively. But, the function is getting called only once.
