  • Show WindowsForm in the center of the Screen (Dual Screen)

    - by serhio
    I have Dual Monitors and want displaying a windows form in the center of the screen. (I have a variable MonitorId=0 or 1). I have: System.Windows.Forms.Screen[] allScreens=System.Windows.Forms.Screen.AllScreens; System.Windows.Forms.Screen myScreen = allScreens[0]; int screenId = RegistryManager.ScreenId; // DualScreen management if (screenId > 0) { // Possede 2-ieme ecran if (allScreens.Length == 2) { if (screenId == 1) myScreen = allScreens[0]; else myScreen = allScreens[1]; } } this.Location = new System.Drawing.Point(myScreen.Bounds.Left, 0); this.StartPosition = FormStartPosition.CenterScreen;

  • Is it possible to make an online registration process for a course in Google Docs with a cap on registrations?

    - by user61551
    I am trying to build an online registration form for an institute I intern at that is running a training programme with multiple courses and hundreds of applicants. I've done registration forms with Google Docs Forms before, but the tricky spot this time round is that I'm trying to put a registration cap on each of the courses. Every person needs to register for one course in every timeslot, and there are seven or so timeslots. However, as seating space in every venue is limited, we would like to cap registrations per course (venue) to 200 per course, after which either a) the applicant will be informed that they need to register for another course in that timeslot if they apply to a full course, or b) ideal case scenario, the option will be greyed out. Is this possible using Google Docs Forms at all? If not, is there a free alternative that might do the job properly?

  • How to get http requests details in a tcpdump?

  • Win C#: Run app as administrator without UAC prompt

    - by paja
    Hello, I need one of my .exe to always run as administrator without UAC prompt. My program will be installed with setup, which will have for one time admin rights, and I need to perform such step in this setup that my exe will be always executed as admin without UAC prompt. I've found 2 solutions so far: 1) Use custom service, which will elevate the program for me. 2) Use tash scheduler: http://www.howtogeek.com/howto/windows-vista/create-administrator-mode-shortcuts-without-uac-prompts-in-windows-vista/ Is there any other solution? Some manifest probably? Thanks.

  • Qt/win: showMaximized() overlapping taskbar on a frameless window

    - by greg
    I'm building an application that has its own custom chrome. I have turned the default window border off by setting the flag: this->setWindowFlags(Qt::FramelessWindowHint); After this flag is set and the default window border is turned off, any calls to: this->showMaximized(); result in a window that takes up the entire screen, overlapping the task bar. Is there a common work around for this or another method I should be calling instead of showMaximized()? Win7/Qt4.6

  • Simple animation using C#/Windows Forms

    - by clintp
    I need to knock out a quick animation in C#/Windows Forms for a Halloween display. Just some 2D shapes moving about on a solid background. Since this is just a quick one-off project I really don't want to install and learn an entire new set of tools for this. (DirectX dev kits, Silverlight, Flash, etc..) I also have to install this on multiple computers so anything beyond the basic .Net framework (2.0) would be a pain in the arse. For tools I've got VS2k8, 25 years of development experience, a wheelbarrow, holocaust cloak, and about 2 days to knock this out. I haven't done animation since using assembler on my Atari 130XE (hooray for page flipping and player/missile graphics!) Advice? Here's some of the things I'd like to know: I can draw on any empty widget (like a panel) by fiddling with it's OnPaint handler, right? That's how I'd draw a custom widget. Is there a better technique than this? Is there a page-flipping technique for this kind of thing in Windows Forms? I'm not looking for a high frame rate, just as little flicker/drawing as necessary. Thanks. Post Mortem Edit ... "a couple of coding days later" Well, the project is done. The links below came in handy although a couple of them were 404. (I wish SO would allow more than one reply to be marked "correct"). The biggest problem I had to overcome was flickering, and a persistent bug when I tried to draw on the form directly. Using the OnPaint event for the Form: bad idea. I never got that to work; lots of mysterious errors (stack overflows, or ArgumentNullExceptions). I wound up using a panel sized to fill the form and that worked fine. Using the OnPaint method is slow anyway. Somewhere online I read that building the PaintEventArgs was slow, and they weren't kidding. Lots of flickering went away when I abandoned this. Skip the OnPaint/Invalidate() and just paint it yourself. Setting all of the "double buffering" options on the form still left some flicker that had to be fixed. (And I found conflicting docs that said "set them on the control" and "set them on the form". Well controls don't have a .SetStyle() method.) I haven't tested without them, so they might be doing something (this is the form): this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); So the workhorse of the code wound up looking like (pf is the panel control): void PaintPlayField() { Bitmap bufl = new Bitmap(pf.Width, pf.Height); using (Graphics g = Graphics.FromImage(bufl)) { g.FillRectangle(Brushes.Black, new Rectangle(0, 0, pf.Width, pf.Height)); DrawItems(g); DrawMoreItems(g); pf.CreateGraphics().DrawImageUnscaled(bufl, 0, 0); } } And I just called PaintPlayField from the inside of my Timer loop. No flicker at all.

  • WPF win app and browser app

    - by pdiddy
    I'm hearing this alot, that you can develop an app in WPF and run it as a desktop app or in a browser. Is this really true? I've install visual studio 2010 and I see 2 project templates : WPF Windows Application and WPF Browser Application (XBAP). Currently reading a book on WPF, it talks about Page-Base app, which can be use for navigation. To creatre an app to run on your browser you have to use the WPF Browser Application. So if I start with WPF Windows Application template can I run it in a browser ? I am assuming not since most of my class will be Window and not Page ....

  • Error in loading component property (Swing GUI Forms)

    - by Christo Du Preez
    For no apparent reason all my Swing GUI forms using components linked to org.jdesktop.beansbinding.Converter started generating errors when trying to open the Design View: Error Error in loading component property: [JPanel]-filterTextField-converter. Cannot load property type class org.jdesktop.beansbinding.Converter. The property cannot be loaded. Errors occurred in loading... I'm currently using Netbeans 6.8. I opened my project in Netbeans 6.7.1 and all was fine but after a while the same thing happened. Looking at the .form and .java files and comparing it to previous backups, everything looks fine. Even my Netbeans tutorial project no longer works. What can cause this. Any suggestions would greatly be appreciated.

  • Win C#: Refresh Windows Explorer in Win7

    - by Paja
    Hello, My program sets "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" value "Hidden". Hovewer I'm not able to refresh the explorer to take into account this change. I've tried: 1) SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero); 2) SHELLSTATE state = new SHELLSTATE(); state.fShowAllObjects = (uint)1; SHGetSetSettings(ref state, SSF.SSF_SHOWALLOBJECTS, true); 3) SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS, 0, SMTO_ABORTIFHUNG, 5000, ref dwResult); 4) SendMessage(HWND_BROADCAST, WM_COMMAND, 28931 /* Refresh */, 0); Nothing works. So what should I do? If I refresh Explorer myself with F5, then it works. Hovewer I would like some elegant solution, so it would refresh the display everywhere, even in OpenFile/SaveFile dialogs, which are currently open. I'm using C# .NET, Win7. Thank you.

Data flows from industrial machine, setup is fairly simple, but I can't find any good open source examples on parallel port reading for Windows. Do you know a software that does this (and lets me learn how to do it myself), or is there any guideline for parallel port programming on XP? Thanks.

  • can't write to physical drive in win 7??

    - by matt
    I wrote a disk utility that allowed you to erase whole physical drives. it uses the windows file api, calling : destFile = CreateFile("\\.\PhysicalDrive1", GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,createflags, NULL); and then just calling WriteFile, and making sure you write in multiples of sectors, i.e. 512 bytes. this worked fine in the past, on XP, and even on the Win7 RC, all you have to do is make sure you are running it as an administrator. but now I have retail Win7 professional, it doesn't work anymore! the drives still open fine for writing, but calling WriteFile on the successfully opened Drive now fails! does anyone know why this might be? could it have something to do with opening it with shared flags? this is always what I have done before, and its worked. could it be that something is now sharing the drive? blocking the writes? is there some way to properly "unmount" A drive, or atleast the partitions on it so that I would have exclusive access to it? some other tools that used to work don't any more either, but some do, like the WD Diagnostic's erase functionality. and after it has erased the drive, my tool then works on it too! leading me to belive there is some "unmount" process I need to be doing to the drive first, to free up permission to write to it. Any ideas?

  • Unable to connect to MS Access database through JDBC on Win 7 64-bit

    - by Ninad
    Hello. I've been trying to connect to a MS Access 2007 database through JDBC. My JDK is JDK 1.6u18 64-bit and OS is Windows 7 64-bit. But problem is I am unable to create a DSN using Windows\system32\odbcad32.exe because it doesn't show ODBC drivers for MS Access at all, it's only showing drivers for MS SQL Server. When tried to click on Configure for "MS Access Database" (which is an already created DSN, I guess), it first shows error message : "The setup routines for the Microsoft Access Drivers (*.mdb, *.accdb) ODBC Driver could not be found. Please reinstall the driver." And then another message : "Errors found! The specified DSN contains an architecture mismatch between the Driver and Application." I cannot reinstall the MDAC as it doesn't work with Windows 7 (which comes with its own WDAC). The odbcad32.exe in Windows\SysWOW64 does let me create a DSN for MS Access, it shows the drivers installed properly. However, when tried to connect to that DSN through a Java program, I get the following exception : java.sql.SQLException: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application at sun.jdbc.odbc.JdbcOdbc.createSQLException(Unknown Source) at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source) at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(Unknown Source) at sun.jdbc.odbc.JdbcOdbcConnection.initialize(Unknown Source) at sun.jdbc.odbc.JdbcOdbcDriver.connect(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at AccessTest.main(AccessTest.java:19) What might be the problem and what do I have to do to get it working? My OS as well as JDK are 64-bit. Can't I connect to a Access 2007 database, which I presume is 32-bit? Any help would be highly appreciated. Also, in case one thinks this's not a right place for this question, I apologize in advance. Then please guide me to appropriate forum. Another option would be to find a third-party JDBC driver for MS Access. But I do need to know what's wrong with my configuration. :-/ PS : I know there're many better databases available out there, but for few unfortunate reasons, I have to use MS Access only and have to get it working.

  • C# Win Forms Thread Pool - Unresponsive UI

    - by Goober
    Scenario I have a Windows Form Application. Inside the main form there is a loop that iterates around 3000 times, Creating a new instance of a class on a new thread to perform some calculations. Baring in mind that this setup uses a Thread Pool, the UI does stay responsive when there are only around 100 iterations of this loop (100 Assets to process). But as soon as this number begins to increase heavily, the UI locks up into eggtimer mode and the thus the log that is writing out to the listbox on the form becomes unreadable. Question Am I right in thinking that the best way around this is to use a Background Worker? And is the UI locking up because even though I'm using lots of different threads (for speed), the UI itself is not on its own separate thread? Suggested Implementations greatly appreciated.

  • Porting getifaddrs to Win XP

    - by Goz
    Hi all, I'm trying to port a MacOSX app to windows and I've come up against a problem around getifaddrs. Basically windows does not support it. I'm trying to figure a way to re-implement it (for AF_INET and AF_INET6) but the "equivalent" functionality on windows appears to be nothing like the MacOSX support. Has someone done this sort of conversion before? If so is there a nice way I can get windows to report me interface info like MacOSX does?

I use the following code: <% Set objExcelCon = Server.CreateObject("ADODB.Connection") With objExcelCon .Provider = "Microsoft.ACE.OLEDB.12.0" .ConnectionString = "Data Source=" & strFilePath & "\" & strFileName & ";Extended Properties=Excel 12.0;" .Open End With Set objAdo = Server.CreateObject("ADOX.Catalog") ' Set ADOX activeConnection objAdo.activeConnection = objExcelCon ' Loop through tables (worksheets) For i = 0 To objAdo.Tables.Count - 1 response.Write objAdo.Tables(i).Name Next Set objExcelCon = Nothing Set objAdo = Nothing % When I run this i get no error message or anything. Anyone got any idea whats causing this? Best regards, Roy

  • qt on Win CE 5.0 crash

    - by Michael
    Good day all, It's the first time I am using Qt on Windows CE and I ran into an issue. Maybe someone can help me with it. I will describe my set up. I am using XP with Visual Studio 2005 an Qt Add-in version 1.1.2. I downloaded Qt source for Windows CE and followed the instructions on these (http://doc.trolltech.com/4.4/install-wince.html) instructions to build the library for CE. I then used the Visual Studio to create a minimal Qt Windows CE Application. The program runs fine in the CE emulator, but once I try to deploy it on the device it crashes with the following message: Load module: qt_ce_3.exe Load module: QtGui4.dll Load module: msvcr80.dll Load module: QtCore4.dll Load module: CEShell.DLL Load module: OLEAUT32.dll Load module: commctrl.dll.0409.MUI Load module: commctrl.dll Load module: aygshell.dll Load module: WS2.dll Load module: WINSOCK.dll Load module: coredll.dll.0409.MUI Load module: ossvcs.dll Load module: ole32.dll Load module: coredll.dll Load module: MMTimer.dll Data Abort: Thread=8fb09a40 Proc=8c4ecea0 'qt_ce_3.exe' AKY=00040001 PC=012a80b0(qtcore4.dll+0x000680b0) RA=012a8168(qtcore4.dll+0x00068168) BVA=676e4574 FSR=000000f5 Unhandled exception at 0x012a80b0 in qt_ce_3.exe: 0xC0000005: Access violation reading location 0x676e4574. I tried it on two devices from different manufacturers, and the result is the same. Debug version worked on one of them, ran out of memory on the other. Does anyone have any idea what this could be? Thanks in advance, Michael

  • Windows Server 2008 on VPC (Host: Win 7)?

    - by Dan
    Is it possible to test Windows 2008 server via VPC when my host of a Windows 7 machine? I don't see anywhere where it says this is possible? The only VPC images (Windows 2008 R2) that I download from Microsoft state that the host machine must be Windows 2008. Is there an alternative?
