Problem in calling seconday dll from labview

Solved!
Go to solution

Hi,

 

I am using Labview 8.6 for my application. The applciation calls  a dll developed in vc++(main dll).  While executing the application the main dll(vc++) calls another dll(secondary dll) developed in vb 6.0.  

 

During the process, the main dll sends datas to secondary dll to display the datas in a popup window. After getting user acknowledge from the display, the application vi stops.

 

When the application is running first time(running the vi first time after open labview),  the datas sent by the main dll are updated in the display of secondary dll. But, from the second time onwards the new datas from the main dll are not updated in the display of secondary dll. 

 

Again, after closing vi and quitting labview, if i open and run the vi, then the datas from the main dll are updated in the display of secodary dll. But, the data of the maindll needs to be updated in secondary dll without quitting labview.

 

I am using 'Call Library function' to call the maindll.  

 

Can anyone please give the remody for this problem.. 

 

Thanks in advance.

 

Swamy.

Do both dll's reside in the same physical folder as your main vi? Are they included in your project?
