• Game Technologies: DirectX, XNA, XACT, etc. Is DirectX9c realistic for all my UI needs?

  I am currently wanting to use the DirectX 9c UI for all of my UI needs in my game. Like using a MultiListEditBox for a complex trade window tracker editor and also an inventory being able to drag and drop 3d images of my items. Is it realistic Do I need to wait for XNA and how much would it cost I would like to use it for free but if not willing to pay a few dollars. Do I have to use something else like CEGUI or something else Thanks Neither DirectX nor XNA provide any UI libraries. The DirectX SDK has sample UI components in native and managed code, however the code is part of their game template library and tough to extract just the UI elements without using the rest of the library. CEGui, and other ...Show All

• Software Development for Windows Vista What is the rationale behind not having a static method to retrieve the current workflowruntime instance?

  After doing quite some work with windows workflow I am starting to feel that there is one thing that is coming back every time you work with the WF runtime and that is getting the current running instance of the WFruntime. What I just can’t grasp is why there is no static method on the workflowruntime class to retrieve the running instance. (or by name if you have multiple instances running) In every sample you look you see that not having this method makes the developers suffer and you need to make assumptions that are not always true. e.g. take a look, at the WebServiceInput activity and try to use it without the generated configuration when you publish the service. (name the configuration something else then “workflowRuntime”!) ...Show All

• Windows Forms Writing event in Datagridviewcombobox?

  Hi guys, Greetings! I'm creating a datagridview with a combobox column, is there anyway that I can write an event everytime the user choose from the combobox list and when lost focus on it I can control the value to set on the next column like if the user choose from the list as "Chocolates" I can set the value on the next column as "PCS" these values where from the table.

• Game Technologies: DirectX, XNA, XACT, etc. Earlier shader models in D3D10

  Are there any plans to support shader models earlier than 4.0 in D3D10 -- Tim Preston The compiler has a compatibility mode to enable easier compilation of 2_* and 3_0 content, but there are no plans to add support to D3D10 for lower models. Recompiling for the 4_0 model is the supported mechanism. The D3DX9 compiler is going to be updated to be able to handle the new syntax features. That way you can have a single HLSL or FX file that works on both D3D9 and D3D10. Craig Peeper Microsoft, Direct3D ...Show All

• Software Development for Windows Vista Office 2003 Applications asks to Accept/Decline License-Agreement on EVERY Startup on Vista. Why ?

  Hello I have installed Office 2003 Professional (ENU) on Vista Home Basic (DEU). So far, Word Excel etc. work fine ... but they ask me on EVERY Startup of ANY of those Programs to Confirme or Decline the License-Agreement (which is shown in a Dialog Box). As I have Registered, Activated and Accepted what I was asked for - I cannot understand why the same Question about License Agreement comes again and again. Has anybody an Idea what I can do simmons I had the same issue with Vista Business, but after getting used to how Vista 'protects' me, it became obvious what was wrong. Try going to your Program Files directory and finding any of the Office executables (word.exe, excel.exe etc) and right click. Choose 'Run ...Show All

• Visual Studio Team System The Team Foundation Server work item database can not be opened.

  Today when I tried to import a new WorkItem type to our TFS-server I get a strange error-message: === U:\WorkItems>"e:\Program Files\Microsoft Visual Studio 8\Common7\IDE\witimport.exe" /f newBug.xml /t tfs /p Test The Team Foundation Server work item database cannot be opened.

• Visual Studio 2008 (Pre-release) Incorrect default icon in taskbar for WPF applications

  When icon is not specified for WPF application, default icon displayed incorrectly in taskbar. Icons in window caption and taskbar are different, and taskbar icon seems to be incorrect. Is this bug Yes, and likely a recent regression. I'll send a note to the feature owners, but given how close we are to shipping I doubt this will be fixed for this version. If you want to make a bug report at Connect , that'd be great. Thank you for reporting this. ...Show All

• Visual Studio Creating a Menu and Submenu Items

  Hi, I’m having a hard time trying to create a Menu and Submenu items for my addin. I know it should be simple, but somehow it doesn't work as I want. What I'm trying to achieve is that when my addin starts it creates a Menu (let say AddInSample) and some SubMenu items (lets say Item1, Item2 and Item3). Then when I want to handle the clicks on the items. The wizard of Visual Studio generates something like this, adding the Menu in Tools, but I don't know why the item is only enabled when the addin is disabled. And when I enable my addin, the item is disabled. I hope that some could help me with this, it's supposed to be simple. Thanks I'm sorry. I couldn't find the resources of extensibility th ...Show All

• Visual Basic Using DataObjects in an OOP environment

  This question is a little involved, but I would really appreciate some guidance. I have been studying (in my job) how to implement object orientated programming and using data objects to communicate with a data source. I am putting this knowledge to use in my current project - a simple help desk program.   I have a form, which the takes input from the user to display, modify and create records in 4 tables of a SQL database.   I believe that one or more of these statements displays incorrect practice, and would explain the area where I am going wrong.   My form creates my class instances, which interact with my DataSet, which fill and update the DataAdapters, which send and retrieve data to and from ...Show All

• Visual Studio Express Editions oranisation suggestion request

  In C, at least in my micro controller programming environment, it is easy to have a header file, with various routines contained therein, which is placed ahead of the main program. What do you do for c# do you add a raft of classes into Form1, or do it some other way I am concerned about reuseability, I guess (both within the specific program, and in other future programs), hoping that I can cut down on the number of keystrokes I need, in order to create a useful piece of software. Is there an on-line tutorial that is easily understandable that covers this sort of question Thanks, Best Wishes, Ray Thanks, I was looking on it more as marking it as answered as sort of preventing others from answering ...Show All

• Visual C++ DLL questions with Visual Studio using C++

  I'm new to Visual Studio (I have VS 2005 Standard Edition) and I'm trying to learn how to code a DLL with some standard functions I use instead of including a cpp file into every project that needs it. Using the help I got a DLL to work with a Win32 project using __declspec ( dllexport ) and __declspec ( dllimport ). When I try a Windows Form Application I get lots of errors with the linker because of the CLR from what I can tell. I tried various things I read and could never get it to work. I decided to try my hand at a .def file and after reading up on how you write it up I have some questions. Can you export overloaded functions using a .def file From what I read I have to include extern "C" to keep C++ name mangling from ...Show All

• Visual Basic Auto hide Of The Component And Dock On Form

  May i know how to auto hide a component when the user mouse out of it and show it when mouse over it. Something like the toolbox at the right in visual basic.net. Is there any dock properties for form which i can specify it must dock to left, right etc Thank you. Most .NET controls have a Dock property that lets you dock it to the left/right/top/bottom or fill the container. There is also MouseOut and Mouseover events for controls that you can hook into. However if you are trying to recreate the toolbox with docked windows and etc, then what you are doing has probably already been done. I would recommend searching Codeproject for something similar, if you are doing this for fun. I know there are ...Show All
