• Markus Sch. How to parse data from XML file in WPF/E ?

  Hi, Can anyone guide me on parsing data from XML file in WPF/E Please let me know. Regards, Santosh kalkeri Hi Santosh, One of the examples I posted on my blog ( http://cornucopia30.blogspot.com/ ) does this exact item.  The example creates some xml representing a list of images found.  The example is available here: http://cornucopia30.blogspot.com/2007/01/wpfe-basic-wpfe-user-control.html Please note, this example was created with the December CTP, you will need to replace the aghost.js file with the February CTP. Please let me know if you have any questions. If this answers your question, please select "Mark as Answer" Thank you, Chad Campbell ...Show All

• MaGeorge Consuming custom activities at runtime using the WorkflowDesignerControl

  I am using the WorkflowDesignerControl (WDC) to create an application to provide simple enduser workflow authoring. I envision the application working something like nUint, where a user would point to a set of assemblies containing custom activities they wish to consume.  The application would then... 1) Load the assembly 2) Add any types derived from Activity as custom activities in the WDC Toolbox... The problem I run into is that it seems difficult to add a custom activity at runtime.  The only way I could really do it was by tinkering with the SelfHostToolboxItem class and forcing it to specifically load my assemblies. Howver, even when I do this, if I use the custom item on the design surface the WorkflowView ...Show All

• Rhubarb Vista UI regressions compared to Windows XP

  [ MODs: I hope this post is not off topic here, please move it to an appropriate forum if it is. Just don't remove it please ;-) ] Hello fellow devs, This guy points out a number of (semi-)broken UI features in Windows Vista: http://www.intelliadmin.com/blog/2007/01/5-sins-of-vista.html These are generally regressions in useability compared to Windows XP, which is kind of a shame I would say. Please, please, please show this to the Windows Explorer team... We can only hope Vista SP1 ( http://apcmag.com/5098/microsoft_kick_starts_vista_sp1 ) will fix things like these and that it will be released soon (Q3-4 2007 ). Are there any thoughts or comments about this you guys would like to share with me Thanks in advance, -Matthias ...Show All

• pc_bond Unable to create folder in C:\Windows\WinSXS in Vista OS

  Hi, I was checking compatibility of one of my MFC application in Vista OS. Usually if the MFC shared dlls are not present, i used to copy them in WinSXS under folder with the required folder name like x86_Microsoft.VC80.xxxx. (Installing VC++ Redist also didnt work in my case.) And this would make the application work perfectly. When i tried to do the same thing in Vista OS, it failed to create the folder. I removed the read only attributes and tried again but in vain. The error i am getting is "User didnt have enough permission to perform this task" but I logged in as Administrator. I tried to change the security attibutes of Administrator but could not find the Users under Computer Management. Is there any solution ...Show All

• r6rider Unexpected termination of state machine workflow

  I have recently encountered an issue with my statemachine workflow, where the workflow is terminating. I have enabled tracing for the workflow. My workflow is signed. My workflow is exposed via web services. The interface and messages used by the WsInputActivity is located in another assembly, which is also signed with the same key. Here is the output of the error information. Does anyone have any idea what might be going wrong Obviously something is throwing an argument null exception, but the where and the why is very puzzling to me. I havent been able to find any information on the objects in this set of exception details: Description: An unhandled exception occurred during the execution of the current web request.

• RyanB88 Biggest Vista UI change: dropdown lists now look like buttons

  In Vista, a drop down combobox list (CBS_DROPDOWNLIST) now looks exactly like a standard button control (except with a small dropdown arrow on the right). Previously it looked like a CBS_DROPDOWN except it was non-editable. I haven't seen much written about this - why did you decide to make drop down list controls look like buttons In many cases, this makes some dialog boxes look very ugly (especially those with a mix of many dropdown combos, edit controls, buttons, and dropdown lists) Is there a way to force Vista to give me an old style looking dropdown list Some of my users have been complaining or thinking the control is "disabled" i.e. greyed when actually it just looks like a button. They expect it to look like a pre-Vista CB ...Show All

• Baji Prasad Check this out: Vista simulated by WPF/E!

  Wow! Vista simulated online, using WPF/E. http://www.vista.si It is in some strange (european ) language, but you can click and watch... there is everything, windows, movable icons, videos, texts, even some form of a contest I might mention that this link is not new, although they are probably updating it as time goes on...

• feiyu New xp pro machine, MSDTC not installed or configured?

  Hello everyone, I purchased a brand new shiny development machine last weekend (one of the new dual core 2 processor machines...two thumbs way up!). The operating system on the machine is XP Pro. I am coding a C# 2005 winforms application which requires MSDTC and after opening my C# project and running it I noticed that MSDTC is not installed on my new machine. I thought MSDTC was installed on every windows machine but apparently that is not correct. So when I go to component services to look at the Distributed Transaction Coordinator the "my computer" icon has a red arrow over it instead of a green arrow which makes it look like there is a problem. If I click on the "distributed transaction coordinator" folder under co ...Show All

• Keith Henkel dynamically enabling away mode with SetThreadExecutionState

  I have read in MS documentation that an application can dynamically enable "Away Mode" through the registry or by calling the SetThreadExecutionState(ES_AWAYMODE_REQUIRED | ES_CONTINUOUS) routine. Does calling the routine actually change the registry value More importantly, I cannot find the value of ES_AWAYMODE_REQUIRED in any of the SDK documentation. Does anyone know this value Thanks The answer is 0x80. The value can be found in one of the header files in the SDK. ...Show All
