• Visual Studio 2008 (Pre-release) Images with raw pixelsize, not DPI-relative.

  How do i display an image in it's real pixelsize If you just add an image in xaml it will be resized to the image's DPI / the screen's DPI or something like that. The best would be if there's some kind of global property so no images in my app will be resized, but a simple property for the Image will also work fine. I agree with your feedback - I'd encourage you to submit it as feeback on the SDK page on MSDN ( http://msdn2.microsoft.com/en-us/library/ms748873.aspx ). That said, we do call our 96th's of an inch "device independent pixels", or "pixels" for short, though obviously this term is overloaded when we're also talking abour raster images. ...Show All

• Windows Forms control updates and various events

  Hi, In a windows application, I am trying to update a control after all the other updates are processed. Ok, maybe need some clarifications: I have a control containing other controls. Those controls have event handler connected to some of their events (such as updated). What I am doing is this: Load the main control and its controls Update the data bound to those controls Notify that update is completed The problem I run into is that the events fired by the controls occur after the last step (Notify). Short of disconnecting all the signals and reconnecting them (long and manual process), is there a way to let the system know to process the pending events and continue I was under the impression that events we ...Show All

• Visual C# Simplified way to assign date values

  Hi all, i have a Form that allows the user to enter an Hour and Minute value, which I then need to convert into an actual date value, which I am doing as follows... objInspectionHeader.m_dtInspectionDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, intHour, intMinute, DateTime.Now.Second); But to me, this seems very long winded. Is there a more simplified way that I can just assign the entered Hour and Minute value to a date current date Thanks Thanks for the reply. But doesn't that add the hours and minutes onto the current datetime For example: Now = 19-01-2007 13:00:00 DateTime.Now.Date.AddHours(3).AddMinutes(30) = 19-01-2007 16:30:00 I need the hour and minute value replacing their respective values ...Show All
