I use my PC to view CCTV Camera and I are having problems run time errors, and this problem occurs every day, the window that I use is window7. I hope if anyone who has experienced this problem and have the solution please share with me.
I assume you use some sort of PCI capture card for the cameras. If so, reload the drivers for this. The install may have become corrupt. If it is a Windows Visual Basic runtime error, a recent update may have messed it up also. Sometimes hardware does not like updated drivers and such. A driver reinstall with the original disc should cure both ills.
