View 3 Replies.net - Optimization With Visual Studio Or A Logic Bug?
Feb 3, 2011I have an small physics toy application I am developing. It works fine except the particles will not push each other away, only pull towards, I debugged that sub going through it command by command and realised the value 'H' would not change, what ever it was set to during the first pass through the sub is what it kept, the only way to change this value is to manually set it i.e 'h = 1'. Once the calculation is redone on the 'H' value it resets to what it was previously, even though the x1,y1,x2,y2 are all different, thus meaning H should be different.
I think it is me that has made a mathematical mistake somewhere, but I cannot see where it is. I need a fresh pair of eyes to look over my work. Please let me know if you find anything.

Crystal Report And Code Optimization?
Jul 24, 2009Ok, the error I'm getting is "Load Report Failed" and it happens when I need to load a large number of crystal ReportDocument objects. I've searched on this, and there is a property in the registry that you can change to -1 and it allows to load more, however I'm still getting the error, just after I get about twice as many documents loaded.
The report is basically a one page document (for each client in the database with an interest charge). It displays the amount of interest charged, and other information pertaining to the charge. These documents are basically printed out and mailed to the client.
I created a "Print Preview" screen which has a CrystalReportViewer object, and an ArrayList property. The ArrayList property has an array of all reports, and there are next and back buttons to browse through each report. Once they are satisfied, they will print them all out, and I can dispose of the objects.
The solution for this, from everywhere I've seen, is to "Dispose the object after you are done with it". My problem is that I can't dispose it until they are finished with the print preview screen.
Is there a better way to go about this that won't require too much time to code (we are already over the deadline on this project) or a simple solution to get past the ReportDocument limit? Right now it is erroring on report 150., There are 180 records (as of today) that need to be loaded.

View 1 Replies[2005] DataGridView Scrolling Optimization
Jan 26, 2009I have a DataGridView where I bind a datasource (sql query) to it. The row count is high with many columns. Trying to scroll through this DGV is painfully slow.
Does anyone know of any kinds of optimization I can do so that I can scroll faster? Like what is the DataGrid doing when you scroll? Does it repaint every screenful? Does it validate every row? It seems like it is doing something unneeded when a user scrolls.
