  • ASP.NET: Validate text box contains integer greater than equal to zero?

    - by User
    If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator? Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

  • Calling CryptUIWizDigitalSign from .NET on x64

    - by Joe Kuemerle
    I am trying to digitally sign files using the CryptUIWizDigitalSign function from a .NET 2.0 application compiled to AnyCPU. The call works fine when running on x86 but fails on x64, it also works on an x64 OS when compiled to x86. Any idea on how to better marshall or call from x64? The Win32exception returned is "Error encountered during digital signing of the file ..." with a native error code of -2146762749. The relevant portion of the code are: [StructLayout(LayoutKind.Sequential)] public struct CRYPTUI_WIZ_DIGITAL_SIGN_INFO { public Int32 dwSize; public Int32 dwSubjectChoice; [MarshalAs(UnmanagedType.LPWStr)] public string pwszFileName; public Int32 dwSigningCertChoice; public IntPtr pSigningCertContext; [MarshalAs(UnmanagedType.LPWStr)] public string pwszTimestampURL; public Int32 dwAdditionalCertChoice; public IntPtr pSignExtInfo; } [DllImport("Cryptui.dll", CharSet=CharSet.Unicode, SetLastError=true)] public static extern bool CryptUIWizDigitalSign(int dwFlags, IntPtr hwndParent, string pwszWizardTitle, ref CRYPTUI_WIZ_DIGITAL_SIGN_INFO pDigitalSignInfo, ref IntPtr ppSignContext); CRYPTUI_WIZ_DIGITAL_SIGN_INFO digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo.dwSize = Marshal.SizeOf(digitalSignInfo); digitalSignInfo.dwSubjectChoice = 1; digitalSignInfo.dwSigningCertChoice = 1; digitalSignInfo.pSigningCertContext = pSigningCertContext; digitalSignInfo.pwszTimestampURL = timestampUrl; digitalSignInfo.dwAdditionalCertChoice = 0; digitalSignInfo.pSignExtInfo = IntPtr.Zero; digitalSignInfo.pwszFileName = filepath; CryptUIWizDigitalSign(1, IntPtr.Zero, null, ref digitalSignInfo, ref pSignContext)); And here is how the SigningCertContext is retrieved (minus various error handling) public IntPtr GetCertContext(String pfxfilename, String pswd) IntPtr hMemStore = IntPtr.Zero; IntPtr hCertCntxt = IntPtr.Zero; IntPtr pProvInfo = IntPtr.Zero; uint provinfosize = 0; try { byte[] pfxdata = PfxUtility.GetFileBytes(pfxfilename); CRYPT_DATA_BLOB ppfx = new CRYPT_DATA_BLOB(); ppfx.cbData = pfxdata.Length; ppfx.pbData = Marshal.AllocHGlobal(pfxdata.Length); Marshal.Copy(pfxdata, 0, ppfx.pbData, pfxdata.Length); hMemStore = Win32.PFXImportCertStore(ref ppfx, pswd, CRYPT_USER_KEYSET); pswd = null; if (hMemStore != IntPtr.Zero) { Marshal.FreeHGlobal(ppfx.pbData); while ((hCertCntxt = Win32.CertEnumCertificatesInStore(hMemStore, hCertCntxt)) != IntPtr.Zero) { if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, IntPtr.Zero, ref provinfosize)) pProvInfo = Marshal.AllocHGlobal((int)provinfosize); else continue; if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, pProvInfo, ref provinfosize)) break; } } finally { if (pProvInfo != IntPtr.Zero) Marshal.FreeHGlobal(pProvInfo); if (hMemStore != IntPtr.Zero) Win32.CertCloseStore(hMemStore, 0); } return hCertCntxt; }

  • KVM guest io is much slower than host io: is that normal?

    - by Evolver
    I have a Qemu-KVM host system setup on CentOS 6.3. Four 1TB SATA HDDs working in Software RAID10. Guest CentOS 6.3 is installed on separate LVM. People say that they see guest performance almost equal to host performance, but I don't see that. My i/o tests are showing 30-70% slower performance on guest than on host system. I tried to change scheduler (set elevator=deadline on host and elevator=noop on guest), set blkio.weight to 1000 in cgroup, change io to virtio... But none of these changes gave me any significant results. This is a guest .xml config part: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/vgkvmnode/lv2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> There are my tests: Host system: iozone test # iozone -a -i0 -i1 -i2 -s8G -r64k random random KB reclen write rewrite read reread read write 8388608 64 189930 197436 266786 267254 28644 66642 dd read test: one process and then four simultaneous processes # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct 1073741824 bytes (1.1 GB) copied, 4.23044 s, 254 MB/s # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 14.4528 s, 74.3 MB/s 1073741824 bytes (1.1 GB) copied, 14.562 s, 73.7 MB/s 1073741824 bytes (1.1 GB) copied, 14.6341 s, 73.4 MB/s 1073741824 bytes (1.1 GB) copied, 14.7006 s, 73.0 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 6.2039 s, 173 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 32.7173 s, 32.8 MB/s 1073741824 bytes (1.1 GB) copied, 32.8868 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9097 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9688 s, 32.6 MB/s Guest system: iozone test # iozone -a -i0 -i1 -i2 -s512M -r64k random random KB reclen write rewrite read reread read write 524288 64 93374 154596 141193 149865 21394 46264 dd read test: one process and then four simultaneous processes # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 1073741824 bytes (1.1 GB) copied, 5.04356 s, 213 MB/s # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 24.7348 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7378 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7408 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.744 s, 43.4 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 10.415 s, 103 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 49.8874 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8608 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8693 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.9427 s, 21.5 MB/s I wonder is that normal situation or did I missed something?

  • Milliseconds in DateTime.Now on .NET Compact Framework always zero?

    - by Marcel
    Hi all, i want to have a time stamp for logs on a Windows Mobile project. The accuracy must be in the range a hundred milliseconds at least. However my call to DateTime.Now returns a DateTime object with the Millisecond property set to zero. Also the Ticks property is rounded accordingly. How to get better time accuracy? Remember, that my code runs on on the Compact Framework, version 3.5. I use a HTC touch Pro 2 device.

  • What does msvc 6 throw when an integer divide by zero occurs?

    - by EvilTeach
    I have been doing a bit of experimenting, and have discovered that an exception is being thrown, when an integer divide by zero occurs. #include <iostream> #include <stdexcept> using namespace std; int main ( void ) { try { int x = 3; int y = 0; int z = x / y; cout << "Didn't throw or signal" << endl; } catch (std::exception &e) { cout << "Caught exception " << e.what() << endl; } return 0; } Clearly it is not throwing a std::exception. What else might it be throwing?

  • filtering for multiple values on one column. All values must exist, else - return zero

    - by Andrew
    Hello All, I would like to filter one column in a table for couple values and show results only if all those values are there. If one or more is missing, then return zero results. example table +----+--------+----------+ | id | Fruit | Color | +----+--------+----------+ | 1 | apple | red | | 2 | mango | yellow | | 3 | banana | yellow | +----+--------+----------+ example "wrong" code: (this must return 3 rows) select Fruit FROM table WHERE Color = red AND Color = yellow but select Fruit FROM table WHERE Color = red AND Color = green must return 0 rows. (If i use select Fruit FROM table WHERE Color = red OR Color = green i get 1 row which is not what i need) I am using PHP with form where user checks different checkboxes that represent different values of the same column. So when he selects multiple checkboxes, all those values should be in the result set, otherwise no result should be given. Thank you, Andrew

  • How do I retrieve the zero-based index of the selected option in a select box?

    - by Ben McCormack
    Let's say I have the following in my HTML code: <select name="Currency" id="Currency"> <option value="0.85">Euro</option> <option value="110.33">Japanese Yen</option> <option value="1.2">Canadian Dollars</option> </select> Using jQuery, I can use $("#Currency").val() to give me the selectd value, and I can use $("#Currency :selected").text() to get the selected text. What do I need to do to get the zero-based index (in this case, 0, 1, or 2) of the current selection?

  • Fastest way to zero out a 2d array in C?

    - by Eddy
    I want to repeatedly zero a large 2d array in C. This is what I do at the moment: for(j = 0; j < n; j++) { for(i = 0; i < n; i++) { array[i][j] = 0; } } I've tried using memset: memset(array, 0, sizeof(array)) But this only works for 1D arrays. When I printf the contents of the 2D array, the first row is zeroes, but then I got a load of random large numbers and it crashes.

  • Why doesn't Python's `re.split()` split on zero-length matches?

    - by Tim Pietzcker
    One particular quirk of the (otherwise quite powerful) re module in Python is that re.split() will never split a string on a zero-length match, for example if I want to split a string along word boundaries: >>> re.split(r"\s+|\b", "Split along words, preserve punctuation!") ['Split', 'along', 'words,', 'preserve', 'punctuation!'] instead of ['', 'Split', 'along', 'words', ',', 'preserve', 'punctuation', '!'] Why does it have this limitation? Is it by design? Do other regex flavors behave like this?

  • How do I tell gdb how long my zero-length array is?

    - by Joe
    Slightly oxymoronic title! Bonus points for Xcode answer but it's a gdb question. If I have a standard, statically sized array gdb will print all its elements [and Xcode will let me browse through it] but if I have a zero length array, it won't, because it doesn't know. Obviously I can print the array indexes one by one, but I'd like a dump of the whole thing. How do I tell gdb how much space I have allocated for the array to allow it to print the array (or to allow Xcode to view the array). Is it even possible?

  • Where does jQuery fit-in with frameworks like JavaScriptMVC, BackboneJS, SproutCore and Knockout?

    - by Prisoner ZERO
    I have been happily using JQuery for the last 2 years and have been quite sucessful creating some really cool functionality with it...so I am very comfortable with it. I also beleive the future of the web will continue on the current client-side path. However... The next challenge seems to be coming in the form of various controller frameworks: KnockoutJS, BackboneJS, SproutCore, JavaScriptMVC (the list goes on). Additonally, there are some great AMD Loader tools for use like RequireJS or LabJS etc. However, jQuery now has define and then capabilities baked-in. It's getting harder-and-harder to keep track of it all... And now, my task seems to be to evaluate/decide-on a strategic-direction for using some form of either an MVC or MVVM framework client-side...but I have so many questions. Where does JQuery fit-in with the various controller-frameworks mentioned above? Is JQuery used alongside each or do some of them have their own 'JQuery-styled version' baked-in? Are tools like RequireJS still needed if you implement one of the various controller-frameworks mentioned above? Does the define and then capabilities baked-into JQuery now supercede the AMD Loader mentioned above? Which one seems most modular? (see notes below) NOTES: One thing I don't want in any future-framework is the requirement of having to take-in vast amounts of functionality that I don't use. Meaning, I would rather use a framework that is truly modular. For example, to use jQuery UI you have to take-in a lot other core libraries that you might not actually use. I will be experimenting with each one, but some REAL feedback would be great. I've seen some 'similar' questions, but none have really answered the above skew. Thanks in advance!

  • Choosing a JavaScript Asynch-Loader

    - by Prisoner ZERO
    I’ve been looking at various asynchronous resource-loaders and I’m not sure which one to use yet. Where I work we have disparate group-efforts whose class-modules may use different versions of jQuery (etc). As such, nested dependencies may differ, as well. I have no control over this, so this means I need to dynamically load resources which may use alternate versions of the same library. As such, here are my requirements: Load JavaScript and CSS resource files asynchronously. Manage dependency-order and nested-dependencies across versions. Detect if a resource is already loaded. Must allow for cross-domain loading (CDN's) (optional) Allow us to unload a resource. I’ve been looking at: Curl RequireJS JavaScriptMVC LABjs I might be able to fake these requirements myself by loading versions into properly-namespaced variables & using an array to track what is already loaded...but (hopefully) someone has already invented this. So my questions are: Which ones do you use? And why? Are there others that my satisfy my requirements fully? Which do you find most eloquent and easiest to work with? And why?

  • Should I pass an object into a constructor, or instantiate in class?

    - by Prisoner
    Consider these two examples: Passing an object to a constructor class ExampleA { private $config; public function __construct($config) { $this->config = $config; } } $config = new Config; $exampleA = new ExampleA($config); Instantiating a class class ExampleB { private $config; public function __construct() { $this->config = new Config; } } $exampleA = new ExampleA(); Which is the correct way to handle adding an object as a property? When should I use one over the other? Does unit testing affect what I should use?

  • RabbitMQ - How I do configure servers for zero-downtime upgrades?

    - by Terence Johnson
    Having read through the docs and RabbitMQ in Action, creating a RabbitMQ cluster seems straightforward enough, but upgrading or patching an existing RabbitMQ cluster seems to require the whole cluster to be restarted. Is there a way to combine clustering, shovel, federation, and load balancing to make a rolling upgrade possible without losing queues or messages, or have I missed something slightly more obvious?

  • Why am I seeing Zero errors in non-ECC RAM?

    - by Alexander Shcheblikin
    According to sources, memory errors are a very probable event: Some say the probability of a DRAM error is 95% in just 3 days of operation of a computer with just 4 GB of RAM, others say 32% of servers experience at least one error in a month with 8% of DIMMs being at fault. Contrary to those horrors, in my more than 10 years of personal computers use I have seen exactly none of the memory errors. I admit I never paid special attention to the subject. However, I have ventured multi-hour memtest86 runs couple of times and never seen an error either. Some of the factors that IMO should aggravate the memory problems: I build my computers out of the most "bulk commodity" parts: mainstream budget motherboards and the next to cheapest memory. also I usually max out the technology available, e.g. in the times of 32 bit OS'es I used 4 GB of RAM and with the current desktop CPUs and the newer 64 bit OS'es I use 32 GB of RAM. memory usage is moderately heavy with lots of virtual machines up running small and big tasks 24/7/365. But nevertheless, no memory-related problems ever found! How's that?

  • Windows Explorer - How can an large file have a zero "Size on disk" value? What does it mean

    - by Jaans
    I would expect some discrepancy between "Size" and "Size on disk" in Windows Explorer due to file system allocations etc. Below is a screenshot of an example file on a Windows 2012 R2 file server that has a 81.4 MB "Size" but for the "Size on disk" it's 0 bytes. What gives? I have other files doing the same, but yet another set of files and folders behaving as expected showing the size on disk relatively close to the actual file size. The volume is a basic disk, formatted with NTFS and the default 4K allocation units. No compression is set for any file or folder on the volume. (For those more paranoid, I did a malware scan, and also confirmed there is not ADS streams associated with the file in question). The user account running Windows Explorer is the domain administrator, and the file owner is also the domain administrator. Thanks for reading!

  • Milliseconds in DateTime.Now on .NET Compact Framework always zero? [SOLVED]

    - by Marcel
    Hi all, i want to have a time stamp for logs on a Windows Mobile project. The accuracy must be in the range a hundred milliseconds at least. However my call to DateTime.Now returns a DateTime object with the Millisecond property set to zero. Also the Ticks property is rounded accordingly. How to get better time accuracy? Remember, that my code runs on on the Compact Framework, version 3.5. I use a HTC touch Pro 2 device. Based on the answer from MusiGenesis i have created the following class which solved this problem: /// <summary> /// A more precisely implementation of some DateTime properties on mobile devices. /// </summary> /// <devdoc>Tested on a HTC Touch Pro2.</devdoc> public static class DateTimePrecisely { /// <summary> /// Remembers the start time when this model was created. /// </summary> private static DateTime _start = DateTime.Now; /// <summary> /// Remembers the system uptime ticks when this model was created. This /// serves as a more precise time provider as DateTime.Now can do. /// </summary> private static int _startTick = Environment.TickCount; /// <summary> /// Gets a DateTime object that is set exactly to the current date and time on this computer, expressed as the local time. /// </summary> /// <returns></returns> public static DateTime Now { get { return _start.AddMilliseconds(Environment.TickCount - _startTick); } } }

  • How do I remove an array dimension where the elements sum to zero?

    - by James
    I am assigning a 3D array, which contains some information for a number of different loadcases. Each row in the array defines a particular loadcase (of which there are 3) and I would like to remove the loadcase (i.e. the row) if ALL the elements of the row (in 3D) are equal to zero. The code I have at the moment is: Array = zeros(3,5) %# Initialise array Numloadcases = 3; Array(:,:,1) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; %# Expand to a 3D array Array(:,:,2) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; Array(:,:,3) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; Array(:,:,4) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; %# And to remove the second row: for i = 1:Numloadcases if sum(Array(i,:,:)) == 0 Array(i,:,:) = []; end end At the moment, the for loop I have to remove the rows causes an indexing error, as the size of the array changes in the loop. Can anyone see a work around for this?

  • FindWindowEx from user32.dll is returning a handle of Zero and error code of 127 using dllimport

    - by puretechy
    I need to handle another windows application programatically, searching google I found a sample which handles windows calculator using DLLImport Attribute and importing the user32.dll functions into managed ones in C#. The application is running, I am getting the handle for the main window i.e. Calculator itself, but the afterwards code is not working. The FindWindowEx method is not returning the handles of the children of the Calculator like buttons and textbox. I have tried using the SetLastError=True on DLLImport and found that I am getting an error code of 127 which is "Procedure not found". This is the link from where I got sample application: http://www.codeproject.com/script/Articles/ArticleVersion.aspx?aid=14519&av=34503 Please help if anyone knows how to solve it. UPDATE: The DLLImport is: [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle); The Code that is not working is: hwnd=FindWindow(null,"Calculator"); // This is working, I am getting handle of Calculator // The following is not working, I am getting hwndChild=0 and err = 127 hwndChild = FindWindowEx((IntPtr)hwnd,IntPtr.Zero,"Button","1"); Int32 err = Marshal.GetLastWin32Error();

  • XNA 4.0 SpriteBatch.Draw Out Of Memory Exception Thrown

    Well, first of all, my guess is that I'm calling the spritebatch.draw() method to many times, but I need to (Or, it's the only way I can figure out how to) Draw my in-game windows.

It throws an Out Of Memory Exception, but I don't know and can't find any other topic or post on this relating to spritebatch. Does anybody have any suggestions on how I can get this working and not take up much memory? I would think this as an easy, cost effective way of drawing a window. I'm just not sure how cut down on my draw calls, or get any of that memory back.

  • How do I make the first row of an Excel chart be treated as a heading when it's a number?

    - by Andrew Grimm
    Given a data sample like Prisoner 24601 0.50 Day 1 80 90 Day 2 81 89 Day 3 82 90 Day 4 81 91 What's the easiest way to tell Excel that 24601 and 0.50 are data series names rather than Y axis values when creating a line chart? Approaches I'm aware of: Turn Prisoner numbers into text by having ="24601" and ="0.50" Only select rows 2 onwards as data, and then add in the labels once the graph has been created? Approaches that don't appear to work: Ask Excel to format the first row's numbers as text.
