Office 2003: Host an Interactive Visio Drawing Surface in .NET Custom Clients

  

Microsoft Office Visio 2003 introduces a new drawing component that allows you to embed an interactive drawing surface into your application's user interface. You can drive the Visio drawing component from events in your host application or with data from a Web Service and an ADO.NET data adapter. The Visio drawing component supports the rich Visio application programming model, giving you control over how graphics are used and displayed on the drawing surface. This article explains how to embed the Visio drawing component into a C#-based Windows Forms client app that retrieves data from the Fabrikam 2.0 Web Service.

Hi,I am facing a strange issue in Visual Studio 2008 Standard SP1, when using WPF Designer (even without using the Designer tab, only XAML tab). Visual Studio crashes very often, without any apparent reason, and in various ways, for example: exits instantly, the IDE displays corrupted UI, when begining compiling it stops responding.There are two new Event Log entries after this: EventType clr20r3, P1 devenv.exe, P2 9.0.30729.1, P3 488f2b50, P4 system.drawing, P5 2.0.0.0, P6 4889dec2, P7 33d, P8 18, P9 system.outofmemoryexception, P10 NIL. .NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (7A2E0F92) (0)Worth mentioning:- computer has Windows XP SP3 with the latest updates installed- it crashes on other computer types too- the project has quite a large number of UserControls - it appears that if opening a XAML file with the XML editor instead, it works ok- on other WPF projects it also works okDoes anyone have an ideea why is this happening and solutions? Thanks

Interactive Sort - problem when toggling

  
I have created a matrix with a toggle option on one of the rows (when the report is initially run this row is hidden).  This row when toggled produces 10 or more rows with data.  In the column headings I have given the user the option to interactively sort through the data that is stored in this row.  The problem that I am having is that when I choose to sort the data after I have toggled to see the data, the report re-renders and the goes back to the un-toggled view.  So I have to re-toggle to see what my sorted data. I want to be able to view my sorted data without having to toggle back out. I believe the solution lies in Row visibility "show or hide based on expression".  I just don’t know what expression to use... or if the solution is more complex. Help please.

Visio Web Drawing Not Working

  
Hello   I have created a Visio 2010 Drawing, and saved it as a web drawing to my sharepoint 2010 server. Visio 2010 - Version: 14.0.4760.1000 (32-bit) SharePoint 2010 - Version 14.0.4763.1000 (64-bit) When i create a page and add a visio web access webpart and then open my web drawing i get an error which reads: 'The Server failed to process the request' The Event Viewer shows the following error: Failed to get Vector Diagram for visio file page Exception : The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs. I have tried google, bing and technet but cant find an answer. I have a secure store target spplication id set up and credentials set and have added that information to the visio graphic service global settings. Any ideas what i can do to fix this issue?

Bitmap drawing

  
I am trying to draw objects (line, etc) on a Bitmap. However, I have run into some problems: the origin of the bitmap coordinate system is at the top-left corner of the bitmap. How can I have it set to the bottom-left corner? Also, I need to draw some real world objects on this bitmap: how can I transform or map the real world coordinates on the bitmap coordinate space? Any help is really appreciated as I am totally lost on this one.

XmlSerializer: Serialize an array of System.Drawing.Color

  
Ok,  here is my problem... I am building a UI configuration tool that utiliizes a PropertyGrid.  One of the properties is a indexed list of Colors contained in an array: CategoryAttribute("Style"), DisplayName("Data Set Colors"), DescriptionAttribute(""), XmlArray("SetColors"), XmlArrayItem(ElementName="Color",Type=typeof(SColor))] public Color[] SetColors { get; set; } The beauty of the PropertyGrid is it knows how to handle this Poperty and properly handles array and list of Colors. BUT...   As we already know in order to serialize a Color,  we have to use a surrigate property,  which is very unfortunate, and I fear is one of those little thing MS just overlooked.  (I understand it is actually a structure and not a class and has not default properties from which to get type info from.) I am really amazed that when I do serialize the class,  the XML is soooo  close to what I need,  its just missing the actual color value data: <AppGridColumnConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name>Label</Name> <SetColors> <Color /> <Color /> <Color /> </SetColors> <IsDefaultEditable>false</IsDefaultEditable> <IsDirtyCheck&
