I have what seems to me to be a truly bizarre problem; I think it's a bug in the .NET 1.1 Framework, but it could be a "feature". Anyway, if there are any .NET programmers in the audience, I could sure use another perspective. I'm working on a reporting application that will allow the user to use two date time pickers to select a start date and end date for a range to report on. The date range will usually be the previous week, month, or quarter based on the current date, but the range could be sometime last year or several years ago. The dates selected in the date time pickers are passed into a custom class I've written to obtain other information etc., but I've confirmed as conclusively as I can that the problem is NOT in my class but with the date time picker control itself. Here's the problem. The date time pickers seem to work fine when I set the dates back by a month or even several. After a certain point, when I set the date time picker back, say, a couple of years from the date it's displaying, I get an error that says "Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks. Parameter name: Ticks". When I take the dates back in shorter spans, say a few months at a time, I can go back as far as I want without the error occurring. It's just when I jump back a longer span all in on go that the error happens. Now, I think I have a clue what's happening, I just don't know how to fix it. I think that the date time picker control must have a certain range in Ticks that it can display, based on the date it is currently displaying. When the date in the control is changed, it updates the range of Ticks to the new values based on the new date. When the value of the control is changed to a date outside of that range, it errors out. Why Microsoft would put that kind of limit, especially one so narrow, on a control is beyond me... unless it has to do with liits of the underlying data type. But that's another discussion. I've been on the web searching for answers all afternoon, and found some related topics but nothing that seems to really help. I would love to have my suspicions on what is happening confirmed, and love even more a (hopefully simple) way around the issue.
