• Visual Studio Events in DSL Elements

  Hi, I started by making a simple DSL solution and customizing property values (i.e define a combo box to display possible values for a property and another "customization" to open a form where I collect several data). Now I would like to define a type for a property, something like "Collection" where I can save the data I collect on a form. I didn’t understant the info on MSDN about "Domain Type Descriptor" and "Property Paths" . Any example How do I handle the mouse click and double click events on a DSL Element Thanks, DevDiver Thanks Herru, The second question is now working. Tks again Concernig the first one, I have done that. The thing is: ...Show All

• Visual Studio Team System Use Rename Refactor to change the schema/owner of an object

  We have recently upgraded our SQL Server databases from SQL2000 to SQL2005 and would like to take advantage of the schema functionality in SQL2005 by reorganizing our database objects (tables, views, functions, stored procs) into various schemas. My understanding is that what in SQL2000 was considered the owner is now the schema of an object. Therefore all of our objects were previously associated with dbo as the owner and in SQL2005 now appear with dbo as the schema. Is it possible to use the rename/refactor functionality in VSTE for Data Pros to change the schema of an object from dbo to something else and then preview/execute changes to all locations that are referrring to the object To clarify t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is adding every asset used to the project a necessity.

  As I ask this, I suspect that the answer may be that I just don't know enough about the content pipeline. In previous hobbyist games I've worked on, it's been common to have a file that specifies a level or UI setup including which textures to load. The game parsed this file and loaded the textures appropriately. This separated the art from the code and allowed artists to modify or create new levels without any work in Visual Studio. My understanding is that any asset that is used must now be added to VisualStudio if it is to be loaded through the ContentManager. Does this mean that when I create such a file which defines a level (including all assets) I must also add all of these assets to VisualStudio This seems.... to put it directl ...Show All

• Commerce Server Sample Order Pipeline Component (for tax) published

  I just realized that my only reference to this was buried in another thread. If you are looking to build a custom order pipeline component I've posted a sample tax component which highlights a number of what I have found to be useful practices (I won't claim best because I'm not speaking from the position of the product group). Some of the useful bits include: Framework for unit testing pipelines and components using the VSTS testing tools. SimpleList / Dictionary wrappers for building strongly typed classes of the pipeline dictionaries. A pipeline category attribute to make component registration easier (no more pipeline component registration wizard needed). Example on how to get the most information out of run-time err ...Show All

• Visual Studio VS2005 hangs Downloading symbols

  i do quite a bit of BHO debugging with IE and what i encounter occasionally is this: vs2005 hangs (and of course the debugee IE) and the statusbar says "Downloading symbols for ...." some .dll. eventually i either have stop the debug (which is not too bad) or kill vs2005. any idea why this happens Gchippie, It loos like we are running into similar but unrelated issues. You can file a bug on the hang here and a suggestion here: http://connect.microsoft.com/site/sitehome.aspx SiteID=210 or call support and see if this is an issue they know about. In the mean time if it keeps happening and you want a workaround, you can turn off the symbol server but make use of your local cache by deselec ...Show All

• Visual Studio Tools for Office ServerDocument persistance object error

  Hi, we are deploying a server side solution based on VSTO. On manyof our client sites, we did not install Office / VSTOR as part of our installation. Instead, only a reference to the Microsoft.VisualStudio.Tools.Applications.Runtime dll is kept in our solution, which uses only the ServerDocument class. On a single client site, we have encountered the " Could not create a persistence object for the specified file." when trying to construct an instance of the ServerDocument class. Is there any other dependancy that we should be aware of Thank you very much, Yoav Sion If the ServerDocument usage is trying to Add or Remove customization from the documents, you need to install VSTOR ...Show All

• Visual Studio Is VS Win XP Home Edition Capable??

  Peace be upon you all, Hi All, First of all I'm a newbie so I'm sorry if my question is stupid. I just want to ask if VS 2005 works fine on Win XP Home Edition If so what about the IIS *** IIS isn't in the Add/Remove Components on the Windows XP Home Edition... Thanks for your help You couldn't use VS2003 on XP home because it required IIS. VS2005 however has it's own 'build-in' web server that is uses to run ASP applications from the IDE According to the system requirement for VS2005, you can run it on XP Home SP2. See http://msdn.microsoft.com/vstudio/support/readme/ For all microsoft products, you can find the System requirement on the ms website (might take some searching though ) Regards, ...Show All

• Visual Basic My.Settings Class

  How does one use the MySettings class to save the state of a check box before a program exits When the check box is changed, I save the state of the check box: My .Settings.Item( "Choice" ) = True My .Settings.Save() And then restart the program and call the check box state back when the FORM loads: Me .RadioButtonEnableCH.Checked = My .Settings.Item( "Choice" ) However, it does not recall the check box state correctly – it is always checked. What am I doing wrong Thank you for the response. Here is the code that should work. However, like you have stated, when the FORM loads the button is always checked and I do not understand why.

• Visual Studio Team System Version control API - basic recipes

  I'm working on writing a simple client using the version control API and I'm having trouble with a couple of basic concepts related to server names, local paths and server paths. I'm hoping someone can fill in the gaps with a few recipes - I've looked at some of the samples on various blogs, but haven't found solutions to these basic issues: 1. Given a local path, determine the name of a TFS server that has a mapping for that path (if such a server exists). The code from the example on Buck's blog ( http://blogs.msdn.com/buckh/archive/2005/10/26/485458.aspx ) doesn't seem to work - it never finds a server name. 2. Given a local path, determine the exact name of the server path that maps to it. 3. Given a server path, determine the ...Show All

• Visual Studio Team System Compiling web sites with Team Build

  I am trying to automate the build process. I have 5 web sites and I want to be able to run the team build and then be able to run the aspnet_compiler to publish them to a new server. How do I use the team build to produce all the associated dlls with that website like it is done by right clicking on the web site and clicking 'Build Web Site' Assuming ASP.NET 2.0 Web sites, try changing your platform from "Any CPU" to "Mixed Platforms". This will usually take care of it for you. In terms of deploying, there are various approaches. Most people use copy or EXEC with Xcopy in the build.

• Game Technologies: DirectX, XNA, XACT, etc. CPU problem

  Does any one know about why CPU is up to 100% when I minimize window Thanks You do that by modifying your render loop to detect window state and act accordingly. The render loop is not a D3D thing. But it can look like what's in this article: http://www.mvps.org/directx/articles/writing_the_game_loop.htm Generally, search for the code that's generating calls to your update/render functions and see how it can be disabled during window minimization... ...Show All
