• .NET Development Accesss Properties of Object at Runtime

  I have to access Properties of an Object at rumtime, that means I do not really know the type of the Object. I do not konw which class it declared with. But I have to access all the properties of it, including its value and the type of properties.  I would like to access it similar with Access Hashtable. Does it possible in Dot Net / C# Cheers The .NET feature you want to use is called Reflection.  Basically, this allows you to query an object to find out what properties and methods it has, and to access them.  If you google "C# reflection" you will get a ton of hits.  There wasn't one that looked better t ...Show All

• Windows Forms Firing a button event after form has loaded

  I've got a login screen which if ran with certain parameters logs the user into the product automatically. The problem I have is I try to simulate the pressing of the btnOK to make the product login but I've put this at the end of the load. This results in the screen not being fully drawn before the login starts so it stays half drawn for a few seconds and looks terrible. Ideas appreciated. Assuming VS 2005 you could try the following (I haven't tried these): A. Insert the statement "Application.DoEvents" just prior to you calling the btnOK event. This should let all queued wind ...Show All

• Windows Forms Making child controls of UserControl editable

  I have a UserControl subclass, CompanyInfo, with various controls (Labels and Textboxes) on it. When I'm designing this class, I can edit the controls, move them around etc., which is fine. However, when I build CompanyInfo into a DLL, then add it to the Toolbox and drop it onto a form in the Designer, I can no longer edit and move the various controls that CompanyInfo encapsulates. I have tried setting these controls to public access, but that hasn't helped. I'm using C# in VS .NET 2003. Is there any way to get these child controls to be editable when my subclass is placed on a form If you have ANY solution to this problem, I'd be ha ...Show All

• SQL Server Conditional color in Matrix subtotal column

  I am using matrix in my report with calculated fields, for example I have 3 columns : Actual amount, Budget and Variance. Variance should be in Red if it is negative. I can set up an expression to change the color on the row level, but not in Subtotal ot Total row. I cannot use sum of Fields! values, because Budget amount is also calculated field based on the "Category" value which is columns group on the matrix. So anyway, if I am trying to reference ReportItems!Variance.Value in Subtotal Level, it gives me an error about group scope. How can I access the cells values in subtotal and total group levels If anybody knows any t ...Show All
