• Visual C++ Png does not display properly in GDI+

  Couldsomeone tell me why thispng (http://users.ox.ac.uk/~chri1957/bos.png) will not display correctly using GDI+ It only shows one pixel in the top left corner for me. It displays correctly in all other graphics programs on my PC, including Windows Picture and Fax Viewer (which I assume uses GDI+). Any help appreciated. This is the code I'm using to display the file: PRE.clsCode {font-size:110%;} PRE.clsSyntax {font-size:100%;} TD DIV.clsBeta {display:none;} A:link {color:#0000ff;text-decoration:underline;} A:visited {color:#0000ff;text-decoration:underline;} A:hover {color:#3366ff;text-decoration:underline;} MSHelp\:link {color:#0000ff;text-decoration:underline;cursor:hand;} Gdiplus::Image image(L"C:\\bos.png"); // TRUE ...Show All

• Smart Device Development serial port

  Hi, Im trying to make a program to communicate with something that is connected with the serial port. The device i wanna connect to the serial port knows several commands. So basically there needs to be a simple connection with the port so that i can put commands in the console and the device reply's me and sets its output on the console.

Thanks in advance! You should configure serial port as needed, Open() it and then call Read*() methods to receive and Write*() methods to send data. You can also su ...Show All

• Visual C++ how to add 3rd-party library support into my project for nmake

  Hi, I'm porting a program originally written for Linux to Windows and am using nmake to build my project by 'translating' the GNU makefile to VC++ nmake makefile. My program makes use of a third-party library called 'vs' and let me assume that the vs library is successfully generated and put at 'C:\vx\lib\debug'. Now my question is how to specify library path of 'vs' so that the Visual C++ linker can found and link them into my program. Below is the code segment from the Linux makefile ********************************** LIB_DIR=/usr/local/vs LIB_PATH=-L $(LIB_DIR)/lib LIB_LIB=-lvs -lnr SYS_LIB=-lGL -lGLU myapp: file1.o file2.o g++ -o myapp file1.o file2.o $(LIB_PATH) $(LIB_LIB) $(SYS_LIB) ...... ...Show All

• Silverlight (formerly WPF/E) Windows SideBar

  Is it possible to run WPF/E in a Windows SideBar Gadget I was hoping to build a demo of a SideBar Gadget that plays video, but I can't even get a basic WPF/E file to render in the SideBar. Thanks! Actually I'm not. :) Windows Sidebar gadgets are made up of html + javascript. So WPF/E would be a great fit (if I could get it to work). ...Show All

• Software Development for Windows Vista How to install additional filters into the XPSDrv Filter Pipeline.

  There are a number of references in the documentation that suggest it should be possible to add additional filters, beyond those supplied by the printer driver's manufacturer, to the pipeline. Specifically, the latest Windows Driver Kit (build 5744) says this (on the topic of Filter Pipeline Configuration File): Vendor driver functionality should be primarily in R1 (print processing) and R3 (rendering). You should limit Administrator modification to R0, R2, and RE. The separate regions allow filters from several pipeline configuration files to be combined together in a deterministic way. A separate pipeline configuration can, for example, specify a watermark and an accounting filter that are to be inserted into every dri ...Show All

• Software Development for Windows Vista Windows Vista beta 2 boot menu uses a screen mode not supported by some monitors.

  I cannot see the Windows Vista beta 2 boot menu on my Xerox XA-3 LCD monitor. The menu works with an older monitor. Since the LCD monitor is quite recent, I expect Windows Vista to be fully compatible with it. From what I can see on my older monitor, the Windows Vista boot menu uses a graphical screen mode, or at least a non-standard text mode. Previous versions of Windows used a text screen mode (80 x 25 characters) which works on both monitors. Why not continue to use the text mode im afraid these are the wrong forums to post your question in as these forums are for .NET software development. Best place is over at the appropriate newsgroups: www.microsoft.com/communities Also remember, Vist ...Show All

• SQL Server ODBC SQLFetch problem

  Hi, I have ODBC code reading data from a XLS file. It opens the file, reads the sheets and columns available, then presents a dialog to allow the user to select which columns are to be used to load the data. All of this works, almost. It is a simple "Select A,B,C FROM Sheet1" using SQLExecDirect When using SQLFetch it always skips the first row of data. Thanks, any ideas would be great. Keith Thank you, adding headers does make it read all the lines. I had tried blank rows that has no effect. This is a reader for a user supplied file I have no control over. ...Show All

• Visual Studio 2008 (Pre-release) Convert UIElement to Image or BitmapImage

  Hi ! I'm currently working on a huge project for a client. The application is fully based on WPF and we use translate, scale and rotation transformation all the time on very complexe interactive WPF UserControls. Unfortunatly, our tranformation animations run really slow and I guess this is due to the number of controls and bitmap effects used on our user controls we"re tryin to animate. I tried to replace the user controls with png images, and it's a whole different world. The application runs really fast (about 15 times faster). So I was wondering if they are any Class or piece of code I could use to temporary switch our user controls to Images when I want to anymate (transform) them, and then switch them back to user control when t ...Show All

• Visual C++ DLL with C++ - Design question

  Hi, I come up into a question about which method would be better to write my DLL. 1. Write it purely in C 2. Wirte the class in C++, then use C function wrapper 3. Write everything in C++, and export the whole class Can anyone kindly point out the pros and cons of the above alternatives, and if there're other designs, please kindly let me know too. Thanks! Thanks for your reply. I think I will use C wrapper as I want to build API library but I will use C++ as I want to use OOP. What is the best way to design the wrapper architeture I am thinking use static method in the class, and the wrapper will call the static functions. Question: 1. What about create a new instance of object every time when th ...Show All
