    - Equalizer in VStudio c++ Hi, I'm new in DirectX programming. I'd like to know how can I implement an equalizer for my DSound primary audio buffer wich is a mix of various sounds. Can I do that through Direct Sound or do I have to use DirectShow can this object interact (I mean, can I create a secondary buffer in DirectSound and equalize it through DirectShow) thanks Roberto Tag: what is the StartRuntime's funtion

    - live video overlay at 20% cpu on primary monitor, 100% cpu on TV out?? Hey everyone, I am doing overlays onto a live TV broadcast and have written a custom VMR Allocator-presenter to do the job. I render my overlay ( bitmaps and/or text ) onto a DIrectDraw surface and blit it over the video within the 'PresentImage' routine. Recently I tested my program with full screen playback on the TV output from our units ( they only have basic onboard video cards) and the CPU usage jumped to 100% with choppy playback. With full screen on the primary monitor I get CPU usage of 20% with great playback even with overlays. I have also tried playing the capture feed in a window, and as soon as any part of the window hits the second monitor the CPU again jumps to 100%. I ran the DirectX Diagnostics tools to check the capabilities of the second monitor, and found that ‘AGP Texture Acceleration’ is unsupported. This is the only difference I can find between the two monitors. Could this be the cause of the problem I have also tried setting the default monitor to the secondary monitor through the IVMRMonitorConfig interface and performance didn’t improve. Finally I get good performance on the second monitor when I remove my all my code used to perform overlays and call the standard VMR presentation routine, which may suggest that the video card does not like when I use the DirectDraw surfaces to perform overlays on the secondary monitor. Has anybody here experience anything like this before I was thinking that perhaps the DirectDraw surfaces may not be handled by hardware for TV output, although I hope this is not the case. Any suggestions would be greatly appreciated.I hope this makes sense, if anyone would like more detail juat let me know. (and hello to Michel R, you will recognise this question im sure!)

    - Vista and Symantec Ghost 8.x I was so excited when I can across your comments on using the BCDEDIT command to change the BCD entries. One problems though, when I try to run the command "bcdedit /set {bootmgr} device boot" I recieve a message that states "data store could not be opened, Access is denied" I am logged in as the Administrator, so I am not sure what is going on. I do get a pop up windows when I try to do administrative tasks from within windows wanting me to verify to continue. Is there something I am missing, or is there away to do adminstrative tasks withing the command prompt like Linux (aka Sudo). I did notice that if you do a "whoami" command it comes up with your user ID. ***UPDATE*** I got it figured out, all I had to do was un-check the UAC functionality.

    - workflow foundation Installing WinFX A successful installation of .NET Framework 2.0 is the first thing we need to use Windows WF. You need to have the latest version, because older ones don't work with the latest bits. On http://msdn.microsoft.com/winfx/ , click Get the Beta . You need at least, the WinFX Runtime Components along with the Visual Studio 2005 Extensions for Windows WF. Of course, for the latest item you must have a running Visual Studio installation (Express editions won't work). These extensions to the integrated development environment (IDE) are necessary because, although it is possible to create the workflow in code, it makes easier to manage the XML and code-behing files Windows WF uses for its work. Downloading the entire Windows SDK to check other new technologies such asWindows Presentation or CommunicationFoundations is also suggested (formerly known as Avalon and Indigo, respectively). Why Workflows Until now, flowcharts and process schemes were done separately from code, just as a way to organize ideas before writing the actual code. But when the task was finished, the scheme remained just as documentation. Also, the capacity of older computers made impossible to retain all the information of a workflow in memory, and it was difficult to translate from an easy-readable format for human to machine code. Windows WF tries to solve all these problems, making workflow technology available to every single programmer that uses the .NET Framework, and thereby making it general enough to be used in different situations. That seems the natural step from the interoperability concepts in the Framework; if it can execute code written in a bunch of languages, then why not have a tool that translates a conceptual idea of how a work is to be done in real, compliable code Windows WF can be used for document management (for that special task it will be integrated into Office 12 ), business cycles, or page flow (by making use of ASP.NET). There are lots of reasons as to why a developer would choose writing a workflow instead of writing the code. First of all, for programmers, workflows are easier to understand than code, because workflows provide a visual representation of the process. Consequently, code becomes harder to maintain and adapt to new areas. For example, adding a step in the middle of a scheme because we need to have an additional agreement with the user because of newer laws can be real pain for coders, but an easy step for workflow users. In addition, Windows WF provides a way to extend existing workflows without need of recompiling, so general frameworks can be developed and then customized to fit in different areas. Basic Concepts Layers in Windows WF : The first one is the code that uses the workflow, because a workflow is not an application, but instead a set of actions that is executed asynchronously by the engine provided by Windows WF. That's the key to being able to use a workflow in such a variety of scenarios. The interface that allows communication between that engine and the executing process is called the Hosting Layer, which provides some extra services apart from Communication (send an receive events and data from and to the workflow), like Persistence (which allows saving the state of the workflow in a storage media to restore it later) or Tracking (so the actual code running the workflow can log the execution of it). Finally, we find the Runtime Layer, which actually executes the workflow and manages the core services. One different with the other two layers is that Runtime Layer is not extensible, while more services can be added to the Hosting Service. Apart from these layers, Windows WF comes with an integrated designer that by default integrates smoothly in Visual Studio 2005, but which can be used outside it, so any developer could add drag-and-drop support to its own application. Activities and the minimal units in Windows WF : Each activity receives some parameters from the developer, executes it actions, and then the flow is transferred to the next activity. Some examples are Code or IfElse activities. As developers, we can create new activities and use it in our own code or create an Activity Library for selling. We can get new activities at no cost on its official website www.windowsworkflow.net . There are two main kinds of workflows: 1. Sequential: Its actions are executed in some predefined order with a beginning and an end. Examples of sequential workflows may include installations. 2. State machines: These workflows don't have a path, but it's represented as a set of states and transitions between states. Examples are a web shop: you may need approval for mailing, the user could pay via credit card or with a cheque, and each user is in one state and may go to any order depending on previous questions.

    - XPS to GDI conversion This is not a direct answer to your question, but maybe this can help: A possibility is to use the the Harlequin XPS reference RIP Microsoft bought some time ago ( http://www.microsoft.com/whdc/device/print/RRIP.mspx ). This includes an XPS filter. As far as I know, it cannot generate PostScript, but can generate a TIFF from the the XPS pages. From there, in another filter placed after the Harlequin filter, you could convert the TIFF image to a PostScript image that could be printed by a PostScript printer. The conversion would be an easy matter in that case, either doing that programmatically yourself, or using one of the many converters on the market. Not sure that covers your need, only my 2 cents! ;-) /Sas Tag: what is the StartRuntime's funtion

    - Problems with Properties.Settings under Vista. No, I've not been able to figure out what it is. The screensaver still got read and write permission. I've tested that. My guess is that Vista does something to the config file which is being read. Because settings I change when it's running is remembered for the next time it runs. But it's not reflected in the my Preview and Settings mode. This also works the other way. I started on basicly reinvnting the wheel why writing to an XML file where I store the data for all users. Each user got it's own category within the file. Though I've run into some trubble serializing the data. Problem is that I'm somewhat lost in where to look. As I said, I have an idea of what might be wrong, but not how to investigate it. Does anyone know here .NET app saves their data for the Properties.Settings Tag: what is the StartRuntime's funtion

    - Windowless activated ActiveX ported from VC6 not painting under VC8. I have an ActiveX control from VC6 which was working fine. It supports windowless activation. This control is placed on a CDialog based class. I used the wizard to create a wrapper class and include an instance of it as a member of said dialog. The control is created and it actually gets click events if I click where I think it should be so it is just not painting correctly. Then I found that the OnPaint in the CDialog derived class it lives on, was overridden and it is not calling the base. There is a comment from VC6 class wizard to not call the base CDialog :: OnPaint. I eventually also found out that CDialog :: OnPaint is where it checks for control containers and relays paint messages to them. Calling the base CDialog :: OnPaint gets me closer, but the control now covers the entire dialog. The OnDraw within the control calls ::GetClipBox on the ATL_DRAWINFO::hdcDraw DC. This returns a rect which is the entire area of the dialog. The prcBounds of the same struct shows the correct control rect. So my questions: 1) Should I now be calling the base CDialog :: OnPaint if it is overridden in the derived class This is a change from VC6 to VC8 Or is there another way to have MFC trigger the OnDraw for the windowless activated control 2) Why is GetClipBox returning the full dialog rect Thank you very much for any assitance.... Going on three days now with this. Tag: what is the StartRuntime's funtion

    - Calculate the width of a space? So I have a string, like "The cow jumped over the moon." I see how through the GlyphTypeface that I can measure the width of each individual character. What works great! What I can't figure out how to do is get the width of the space between the words. Let's say I have the following method: Code Snippet public double CalculateWidthWithSpaceAtTheEnd() { double width = 0; ushort glyphIndex = 0; Geometry geo = null; foreach (char ch in Text) { glyphIndex = Typeface.CharacterToGlyphMap[ch]; geo = Typeface.GetGlyphOutline(glyphIndex, EmSize, 10); width += geo.Bounds.Width; } char spaceChar = ' '; glyphIndex = Typeface.CharacterToGlyphMap[spaceChar]; geo = Typeface.GetGlyphOutline(glyphIndex, EmSize, 10); width += geo.Bounds.Width; return width; } I would think what that would do is add up all the widths of the individual characters in a string, then get the width for the space for that font, size, and hinting, and add that to the total width, giving me the width of a word with a space at the end. However, the width in the bottom portion comes out as -Infinity...which obviously isn't really getting me what I want. Any clue Or, does anyone know of a way to calculate the actual width of a string (like "The cow jumped over the moon.") without having to go through the task of measuring each individual character Any help would be appreciated.

I had a try.

I run a workflow,not use the startRuntime();

the instance works all the same.

so,what is the StartRuntime's funtion.

in which condition,we must use it.

Re: what is the StartRuntime's funtion

Joel West

StartRuntime will be called under the covers if you ask WorkflowRuntime to run an instance. However in some cases you may want to start the runtime without running an instance (for example in order to load and run instances that are dehydrated but are ready to run). For this reason there is an explicit StartRuntime method.

Thanks,
