Hi All,
I don?t know if many people on this user board know about ?Windows Form User Controls?? These controls are designing tools for programmers to design GUIs (Graphical User Interfaces). I?m going to talk about a control called the ?
DataGridView?.
One major problem with the eRx is slowness redrawing of cell rows. This is mainly due to the DataGridView control. The DataGridView is a user control that a programmer drags to a Windows form (design view), or programmatically write code to build during development. For some time, Microsoft Visual Studio has had some bugs associated with their DataGridView user control.
One of those bugs happens to be dealing with GDI+ (Graphics or Drawing) for NVidia Graphics (Video) cards. This is mostly with older NVidia graphic (video) cards, mainly in older Windows XP PCs. There are many flavors of NVidia cards (Quadro, GX, GT(S/X), Geforce, etc.). That?s what makes this problem a little more challenging. Not all NVidia cards have this issue, but the majority of the older cards do. The DataGridView doesn?t error much with other graphic cards such as, ATI Radeon.
To: AC Loyal Users: Another possible solution to correct this problem with the slow processing prescription writer (eRx) is, update your graphics (Video) cards drivers, on older PCs. Whichever PC brand (Dell, HP, Gateway, etc.) you will have to go to the manufacture?s website, and download the latest video (graphic) driver for your video card.
If that doesn?t solve the problem then? There is a wonderful step-by-step workaround posted by Sandeep
here.
To: AC Core Development Team (AC developers): The MS DataGridView does not get along very well with NVidia?s older graphic cards. This is partly Microsoft?s and NVidia?s fault. Of course, big money is involved, that?s why it?s not out in the open, on Microsoft?s or NVidia?s forums. They (Microsoft and Nvidia) have worked these issues out for the new .Net Framework and new PCs, currently on the market. But nothing was said about the older stuff. Go figure! That?s up to us (the developers) to figure out. Below are some very helpful forums that have helped me in the past.
