• Windows Forms Capturing Keystrokes

  Is there a way i can capture application-wide keystrokes in my application Basically, i want an event to fire whenever i press Ctrl+Shift+C anywhere in my application. It only needs to capture it if the application has focus i.e. i dont need to capture keystrokes sent to other applications. Is there an easy way to do this, or an example someone can give me for it If only there was a in MyApplication_Keydown in the application events section... You can do this by registering and IMessageFilter object that will handle the WM_KEYDOWN message enabling you to handle the event application wide. The only restriction I'm aware of is that you won't receive the message while a message box is shown (in ...Show All

• Visual Studio Express Editions Recording MP3 FIles

  Hi, I am making an audio recording program and i am wanting to know if it is possible to record audio from a selectable source (Microphone or Line In) and save it to a file in a user selected directory. I have a dropdown box with the items: 'Line In' and 'Microphone' and named 'inputselect'. A textbox for the folder to save to named 'tbsavedir' . Another text box for the file name called 'tbfname' . And finally two buttons named 'recstart' and 'recstop' for starting and stopping the recording. Any help would be great. the managed DirectX SDK has those exact samples! you can do it but you would require managed DirectX to do this, there are samples in there (with full source) so you can look at it and use it if you like http:/ ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Exchange Frame Buffer for Texture

  Greetings everybody, My Problem is that I need to "grab" the Output from the Framebuffer, no matter what it currently displays, and use these frames as textures for further manipulation in Direct3D. The difficult thing here is that I don't want the Application to first write the complete Frame in the normal Framebuffer, then read it to a texture but directly set the Texture as the Framebuffer, alter the texture and finally write the altered Texture into the normal Framebuffer for display. And this shall not work only for 3D-Rendering or Video-Display, but also with normal Desktop-Apps and even the bare Desktop itself. So I think I must find a way to reroute the Frames heading to the Framebuffer for display to "my own" F ...Show All

• Visual C++ C++/CLI Types

  Hey All, When I was using Managed C++ back in the old days of VS03, I remember being very careful to use Int16 instead of short, and Strings instead of std::strings. I'm wondering how much of a difference that makes w/ the new CLI. Is "int" equivalent to "Int32" as far as garbage collection and such Also, I caught myself doing this today when I declare variables. String ^str; but when i do my arrays, I put the handle like this... array<String^>^ str; Where is the 'proper' place to put the cap The standard just defines something like this sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) ...Show All

• SQL Server sql data types vs is data types

  Hi, I want to store a decimal value which I get from an execute sql task into a package variable. Which data type should I specify when creating the package variable Thanks, Tom Jamie, If I store my recieved decimal value in a float variable and further on I want to insert this value in another table (into a decimal column, so in the parameters tab I select as data type decimal again -otherwise the db complains-), I get this great error: "Error: The type of the value being assigned to variable "User::TechnicalPrime" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object." So I don't know how you guys do this but just switc ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Packaging assets

  I haven't got into using XNA as of yet, however I very much like the idea to play my games on the Xbox360 (blah blah blah). I see that the XNA team has put large amounts of effort into some asset management in XNA, that includes the XACT audio cues for like "make it possible to change the sound triggered by some event without doing it in the programming". I'm fairly deep into the process of making my customized packaging format with the goal to essentially archive anything (textures, sounds etc) into a single or more packages. There are several reasons, one of them because I started before the XNA project was convened, and to ease distributions on levels and mods by packing several files, textures, sounds, scripts in a single package file. ...Show All

• Smart Device Development CFile::SetLength() exception in Storage Card folder

  In the device emulator, CFile::SetLength() throws an exception when used on files in the Storage Card shared folder. Is this a bug or is that behavior to be expected I've seen some irregularities with write file access when the file is located on the emulated storage card. It seems to be fixed (at least for me it was) in the beta of the emulator 2.0 ...Show All

• Visual Studio Express Editions Install vc++ 6.0 on top of vc++ 2005 express?

  If I install ms vc++ 6.0 pro. ed. (academic price) on top of vc++ 2005 express: will there be a vc++ benefit of functionality or vc++ loss of functionality If I should install and use ms vc++ 6.0 pro. ed. (academic price), should I uninstall anything first, before installing ms vc++ 6.0 pro. ed. (academic price) I did install PSDK and enable MFC with the vc++ express and it works well. Thank you. B. John OK, so for the computation part things are pretty clear. Use Visual C++ Express, ignore VC++ 6.0. For the visualization part it really depends on what exactly "visualization" means for this project so I'll add just some very general thoughts: For simple graphs even the old Win32 GDI (or GDI+) can do t ...Show All
