Two strange things are: 1. The exception SHOULD actually be handled as I have a Try ...Show All

• Visual Studio Team System Extending Team Portal to have calendar...

  Hello, I'd like to try to extend a team portal to add a Calendar to the portal.  I thought there would be some type of Web part that did this i.e. mycalendar.  To my dismay I have not found that or any other web part that I could use.  My question is: Is there a calendar available for the Team Portals   If so, where can I find this calendar Thanks a million in advance. BJHop FYI we are using Conchango's Scrum for TFS process template. The Event's web part is part of the basic install of SharePoint 2.0 and 3.0. I'd be very surprised if you don't have it. Are you the WSS administrator If not, I would ask him/her about it. You should be able to see it by simply selecting 'Modify shared page/add ...Show All

• Smart Device Development skipping among controls of form

  when navigate through controls that placed on Form (or panel), the ‘next’ of the last placed control is the first control that placed on the form (with the assumption that we keep the tab order..), my question how can I change the form behaviors that when last control is focused, this skipping will not take place (the only way to move will be up), like all the native menus of the WM OS. thanks, Oren I had to get a little more into the detail to fix this issue as although the above is the obvious case, if you have a full screen of nonfocusable controls this create a similar problem; bascially these controls are jumped over. I override the dpad-up and dpad-down. In this override I find the nex ...Show All

• Architecture Implementing DTO's in.Net

  Hi, Can anyone suggest some good approaches to build Data Transfer Objects using .Net custom classes. Also would like to make them bindable friendly. Meaning when I have an array of entities and would like to bind the same to a datagrid. what interfaces do I need to implement to make it bindable to the datagrid. Thanks Sai Hi Sai, I invite you to check an article published in SkyScrapr a couple of weeks ago Passing Data Between Layers and/or Tiers That article comments about DTO and particularly mentions a free way to take advantage of its benefits in the .NET platform, thanks to the typed datasets (not just mere ADO.NET datasets but domain classes backed on datasets) Hope ...Show All

• Software Development for Windows Vista Custom class as an activity property and the property grid

  I wish to have a simple class containing only primitive types (string, int, etc.) as a property for an activity. However, after adding the property and dragging it onto the workflow, the property grid does show my property correctly. I would like to be able to expand it so I can see and set each individual property of my custom class. I have tried adding [TypeConverter(typeof(ExpandableObjectConverter))] as an attribute to my property, but it did not have the desired effect. Can anyone give me some pointers to accomplishing this I'm new to WF so this is a learning process for me. Thanks, Chris Hi, which property has to be initializied in which constructor Can you post your code here T ...Show All

• Visual Studio 2008 (Pre-release) Rolebased Security & controls

  Hello, For my WPF application, I need to use rolebased security to: a) Disable buttons b) Make controls readonly or read/write I'm planning to use an access matrix for each role. Each control has a boolean that indicates if it is enabled or if it is readonly. It just seems like a lot of work, and lot of binding code (in xaml-binding and cs-properties). aya-yaya... Is there a way out of this Is there a better approach Thanks Houman Josh, that is a great idea! I really like that. Unfortunately my problem is a little bit crazier than the regular rolebased security :( The admin can configure which controls are enabled or disabled for each role. Thanks Houman ...Show All

• Visual C++ Why is casting needed in this example

  I am a little stuck understanding why casting is needed in the following example (Example taken from MSDN website):- // A simple program that uses LoadLibrary and // GetProcAddress to access myPuts from Myputs.dll. #include <stdio.h> #include <windows.h> typedef int (*MYPROC)(LPTSTR); VOID main(VOID) { HINSTANCE hinstLib; MYPROC ProcAdd; BOOL fFreeResult, fRunTimeLinkSuccess = FALSE; // Get a handle to the DLL module. hinstLib = LoadLibrary(TEXT("myputs")); // If the handle is valid, try to get the function address. if (hinstLib != NULL) { ProcAdd = (MYPROC) GetProcAddress(hinstLib, TEXT("myPuts")); // If the function address is valid, call the function. if (NULL != Pr ...Show All

  Is it possible for me to configure the VB.NET2005 IDE to have a different default location for my macros (the VSMacros80 folder) Currently, they are always created in my "projects" folder, but I'd like them to be created (and maintained) somewhere else (perhaps a "macros" folder.

In the form, how do I insert a paragraphc explaining what this app. is going to be I tried the Lable control but it does not give me multi-line option. What do I need to use Thanks! I remember in VB6 how you could edit the text directly in the designer window. It was sometimes convenient, but more often then not I ended up double-clicking on the control and generating an event, instead of "slow double clicking". Editing the text in the properties window is the way it's done in .NET. ...Show All

• Smart Device Development Remove Webbrowser Control

  I'm developing a CF 2.0 device application. After the user interacts with the app for a bit, I add a webbrowser control to the UI (thanks to a response in another thread) and navigate to a website. After the user is done there, I intend that a menu key event would remove browser and return the user to my app. After trying to remove the webbrowser control Controls.Remove(webBrowser1); The app hangs with a dead browser still in the display. I verified the statement is hit with a debug breakpoint. What is the correct technique for removing the browser control and restoring the app interface Thanks, Best way probably would be not to add/remove the control, but show and hide it instead. ...Show All
