  • Getting Image size of JPEG from its binary

    - by rajeshsr
    Hi I have a lot of jpeg files with varying image size. For instance, here is the first 640 bytes as given by hexdump of an image of size 256*384(pixels): 0000000: ffd8 ffe0 0010 4a46 4946 0001 0101 0048 ......JFIF.....H 0000010: 0048 0000 ffdb 0043 0003 0202 0302 0203 .H.....C........ 0000020: 0303 0304 0303 0405 0805 0504 0405 0a07 ................ 0000030: 0706 080c 0a0c 0c0b 0a0b 0b0d 0e12 100d ................ I guess the size information mus be within these lines. But am unable to see which bytes give the sizes correctly. Can anyone help me find the fields that contains the size information?

  • Sharepoint: Is it possible to automate the deployment of a custom CAS policy?

    - by user332133
    Hi all, I'm looking for a way to automate the deployment of a custom CAS policy in SharePoint. What i would like to achieve is the following: All assemblies that have been built and signed by our build server (with a secret key) should run in SharePoint under the 'higher than normal' trust level. Now I can manually edit the cas policy files to include something like this: <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="MyPermissionSet" Name="[My Company public key]" Description="Grants all "> <IMembershipCondition class="StrongNameMembershipCondition" version="1" PublicKeyBlob="[public key goes here]" /> </CodeGroup> And that works great. However, we have several huge sharepoint farms, with many applications running on it. I'd like to avoid having to manually edit all policy files to include this xml snippet. Is there a way to automate this? For example, from a feature? With kind regards, Erwin van der Valk

  • IE 8 Errors for Group Permissions for access

    - by Jeff P.
    Hello, The company I work for is about to begin testing for a transition from IE6 to IE8. One of our main concerns is about using permissions to control intranet access to internal sites,etc. This was a problem we encountered during testing for IE7 and scrapped it all together. However, IE6 has more than its foot in the grave, its head is peeking out. Microsoft is only supporting IE6 until 2014 when they also abandon support for Windows XP. IE7 just came up with a box asking for you to enter your credentials. It didn't matter if you had permissions, it always said access denied. We have yet to begin testing but I was hoping someone has encountered this issue as well and may be able to shed some light on the subject.

  • Can "\Device\NamedPipe\\Win32Pipes" handles cause "Too many open files" error?

    - by Igor Oks
    Continuing from this question: When I am trying to do fopen on Windows, I get a "Too many open files" error. I tried to analyze, how many open files I have, and seems like not too much. But when I executed Process Explorer, I noticed that I have many open handles with similar names: "\Device\NamedPipe\Win32Pipes.00000590.000000e2", "\Device\NamedPipe\Win32Pipes.00000590.000000e3", etc. I see that the number of these handles is exactly equal to the number of the iterations that my program executed, before it returned "Too many open files" and stopped. I am looking for an answer, what are these handles, and could they actually cause the "Too many open files" error? In my program I am loading files from remote drive, and I am creating TCP/IP connections. Could one of these operations create these handles?
