• Windows Forms Slow User Defined Control

  I'm creating a custom control that has contained within it a large number of buttons. The code is extremely slow (taking about 12 seconds to display). I've had no success in making it faster. The problem seems to be centered around a single statement: Controls.Add(my_button_ctl); I tried to use the Controls.AddRange(...) member instead of Add(), but there was no speed improvement as was implied in the documentation. If I remove the Controls.Add() call (or AddRange), the display is almost instant. Is anyone aware of a way to speed up a user defined control that contains a large number of button controls In my case there are up-to 550 buttons contained on the control and I would like to get them displayed in under 1 second. The custom ...Show All

• Software Development for Windows Vista Validator, Designer Disconnect

  Hello all, In order to understand how all of the various components of an activity work together as a unit, I am attempting to build an custom activity that enables the user to associate a form with an activity at design time. I have an activity that exposes a FileName property, a designer that allows the user to drag and drop a form from the Visual Studio Solution Explorer onto the activity and a validator that ensures that the FileName property is indeed set. When I add the activity to a workflow it correctly displays a warning stating that the FileName needs to be set. When I drop a form onto the activity the FileName is set and displayed in the properties window, however the validator still shows its warning. How do I let the validato ...Show All

• .NET Development base-method bindings incorrect when updating a referenced assembly

  I have detected some strange behaviour on overriding methods. Hopefully this is by design because if not this could be a major bug in .NET! First of all, I am developing a framework containing multiple assemblies. This framework contains several base classes that developers can descent from. When I update the framework (when fixing a bug) I used to tell customers just to delete the old assemblies and replace them with the new versions I had send them. Sometimes this did not solve the problem. Customers sometimes needed to recompile their entire project against my updated framework assemblies before the bugs disappeared. I now have discovered what causes this strange behaviour. Let me show a small code example: Version 1 of Step ...Show All

• Visual C# Implementing a UI Type Editor – How to get a reference to the property owner class.

  Hello, In my application I am using the PropertyGrid control to edit the properties of a class (MyClass). To edit one of its properties I am writing a custom System.Drawing.Design.UITypeEditor . Like described here: http://msdn2.microsoft.com/en-us/library/ms171840.aspx To validate the property (for witch I am writing the property editor) I need to call a method on the class(MyClass) in which the property exists. My question: how do I get a reference to MyClass, or a reference to the PropertyGrid.SelectedObject from within the UITypeEditor EditValue method public override object EditValue( ITypeDescriptorContext context, IServiceProvider provider, object value) { ........... } Probably via the IServiceProvider GetService ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Dream Build Play Contest Question - Using languages other than C#

  I've managed to use Chrome ( www.remobjects.com ) to create some small XNA demos that use the content from SpaceWars. The rules do not mention whether non C# langauges are allowed to enter the contest. Since there are several .NET 2.0 compatible compilers out there shouldn't this contest allow these entries as well as they can use both the Windows and XBox 360 XNA assemblies. Just to clarify, I have Visual C# Express and Game Studio Express installed on my machine, but am using Chrome via Visual Studion 2005 to write and compile my XNA demos and the plan is to use that combination to write future XNA games and contest entries. Could someone from the XNA contest team please clarify your position on the use of non C# languages for the Dream ...Show All

• SQL Server SSIS Logging to Flat File Destination

  Hi I am trying to use a conditional split task so that I can check for specific fields. If the value doesn't exist I am piping the records to a derived field task, where I add an error. I then try to send these records to a flat file destination so that I can keep track of them. However, when I execute the SSIS data flow task I get the following error [Log Invalid Records [5496]] Warning: The process cannot access the file because it is being used by another process. This file isn't being used by any other process as far as I can tell, and the only process using it is the SSIS task trying to write to it. If anyone has any ideas, then I would really really appreciate it Thanks Darrell I s ...Show All

• Visual Basic All Help Required

  As some of you will know from the questions I've been asking, I have created a screensaver where the user can add a Theme of their own and share it with others. I now need others with more VB Knowledge than myself to take a look at it, add to it, polish it up, make suggestions etc, so that it can be released to the public at large. If you contact me I will zip it up and send you a copy of all the code so far, at the moment it has two Themes, you can choose which one you want to use by using the options form. Thanks for looking.

• Game Technologies: DirectX, XNA, XACT, etc. Deciding where to land the main window when it's constructed

  I have two monitors, one 19" CRT (main) at the right, and a 26" LCD at its left. So far, the XNA examples (the packaged one and some from people) have a tendency of making this window lie on both monitors. There's about 100 pixels laying on my left screen and the rest in the right screen. This makes it the program run VERY choppily, until I move the window fully into only one monitor. Also, while I'm accomplishing this moving task, the mouse cursor refreshes in windows about once per second, increasing the difficulty of that small task. I've tried doing: graphics.GraphicsDevice.Viewport.X = 10; graphics.GraphicsDevice.Viewport.Y = 10; but it doesn't appear as if I can. Well, instead of trying to ...Show All

• Visual C# Is Form Loaded

  How do I know when a windows Form is loaded.. For example.. If i wanted to run a function one the form loads.. how would I do this P.S: Sorry If Im not clear.. but If Im not please let me know. Unfortunately there is no event to detect if form is Loaded or not but i think there is not condition where you really need it strictly and your work cannot be done elsewhere. I would suggest using Load event instead becuase its really close to what you need and Load also occurs after Initialization of all the controls and fields on the form so there is negligible difference between Load event and what you desire to get (Form Loaded). I hope you understand! Best Regards, Rizwan ...Show All
