Hello,
This should be asked in the ASP.Net MVC forum on
forums.asp.net.
As Microsoft's ASP.Net forums are on a different platform, we cannot move the question for you.

  • How to create/read/write textfiles in a jar archive?

    Hi!
    I would like to know how to create, read and write text file in a jar file?
    //Marcus

    You want to update "files" that are inside a jar archive? You can't. At least not very easily; to modify a file you need to create a new version of the jar, copy over everything else, and add the new version of that file. Look for a different design that doesn't require updating a jar.

  • How to create a new template for pages in iPad?

    How to create a new template for pages in iPad?

    In spite of the latest updates Pages for iPad does not support:
    1) User templates
    2) Headers
    3) Footers
    4) Page numbers
    and it is not compatible with Pages for OSX, a document cannot be edited alternatively on Mac and iPad without destroying headers and footers.
    - The Word export is far from perfect
    - Does not really support Page Layout mode (you cannot duplicate a page at least)
    - Does not have a multi-page overview
    - The spelling support of iOS and OSX is at the level of Apple Maps except 4-5 languages.
    - It takes a long time until it starts
    INSTEAD, according to the latest updates:
    - It can do change tracking
    - Lock and unlock objects
    - Add reflections to shapes
    Dear Apple, please understand:
    - We like iPad and we wish to use it for real work.
    - We wish to have user templates, headers, footers and page numbers.
    - We do not expect all the features of Pages for OSX, but we do expect real compatibility.
    - We do not wish to switch back to Word for Windows unless you force us.
    Please try to concentrate on real development not on unimportant changes like in the latest dissapointing update.

  • How to create a page template?

    Hi!
    I need to create a page template. There are any templates and the page preview option show an overview about the region and areas these. I would like to create a based page in this template. I think that I should know:
    1 - How to create the shortcut?
    2 - How to create the page template?
    3 - How to assign a region with a page template?
    Priscila Britto

    Hi people!
    I get to resolve any items. Anything important are:
    - you can to view a structure of page template. The first you view it in the menu Shared Components >> Templates. There is a icon in the column "Preview" for the page, report and region template items. In the click on the icon you can view a template structure that should be shown in the execution.
    - You can view where will be inserted a region on the option "display point". You need to click on the icon in the right of the "display point" option;
    Well, If you pay attention in the two options you will know how to modify a template and how to create.

  • How can I read a template and differentiate if it is a pattern matching template or a geometric matching template?

    Hey all,
    I would like to know how can I read a template´s information to know if it is a pattern macthing or a geometric matching template? 
    In my code, users provide templates and the algorithm must match them using pattern matching or geometric matching depending on the template.
    At the moment I am doing it by including a P or a G in the name of the file, but I would like to avoid this and read the information from the file.
    Any ideas?
    Thanks in advance,

    Hi,
    Please try to setting Folder Permissions on Web Publish, and then deploy it with Web Deploy, as far as I know, if we do that, Web Deploy will use the SetAcl operation to change permissions. Please have a look at the article below.

  • How do I read/write many matrices through TCP server?

    I'm trying to modify the simple data client and the simple data server program in example in LabVIEW6i. How do I send a 2 dimension nummeric matrix? and also how do I send many numeric matrices at a time?

    The problem here is that at the receiving end, one cannot know how many
    bytes to read before unflattenning into the datatype.
    A method that works for *any* datatype (and any data transfer mechanism):
    Flatten the data to string.
    Flatten again the string to string; this adds a string lenght (U32) header
    to the string.
    Send the string.
    When receiving data, first read 4 bytes and convert to U32.
    Read this number of bytes.
    Typecast the string to the expected datatype.

  • How to Create authorization WAD template for BW3.5?

    Hi All
    How To create Authorization for a Web template in Bw 3.5 ?
    I have a requirement to restrict a particular Web templated in bw 3.5 So that all the end users should not be able to access that template only a particular user should be allowed to view the template?
    I cant find any authorization object for the WAD template in bw 3.5 ?
    Can anyone tell me the procedure to include the WAD template authorization?
    Should i include the authorization template in the Menu - in pfcg??? . i have added the template in the Menu in the PFCG but still it didnt work.
    Thanks

    As you said, the authorizations for the WAD templates should be given in PFCG roles.
    But you have to include the access/authorization details in the authorization objects. WAD templates have been created with including info/multiprovider, info cubes right.. first you have to include these objects inside the Role in PFCG.
    S_RS_COMP,S_RS_COMP1,S_RS_MPRO,S_RS_ICUBE.
    just assigning WAD template in the menu of the roles is to display when you login with the userid.
    Please request your BASIS folks to do the same.
    Hope this would help you.

  • I know how to create a PROJECT template, but is there a way to create SLIDE templates?

    Basically I've got several modules, and throughout all the modules is several different pages (text&graphic page, hot graphic page, tab page etc etc).
    What I would love to do is create a set template for each page type (a template for text&graphic, a template for tab page etc) as I have numerous instances of the same pages throughout all the modules (and also for continuity as well).
    It would be great to create placeholders for slide templates just like the application in project templates, and then be able to drop these slides into different projects to have the same foundation to start adding data.
    Project templates is a good start, but only if i want to use the same template throughout the entire module.
    Any one know how to do this?
    Thank yo
    Rich.

    If you're using Cp5/5.5 you can create multiple master slides to them apply to the applicable slides (I don't remember if it was in Cp4).
    Master slides are portable, also, you can copy all the elements and paste them onto new slides in the same project or a different project.
    Insert > Master Slide
    Which should create a new blank slide in the Master Slide panel.  You add items to the slide like backgrounds, captions, rollover captions, highlights, shapes, animations (buttons/click boxes are not allowed).  You use the timeline as you would with a 'normal' slide, but you can't adjust the length of the master slide (this doesn't impact the length of a 'normal' slide).
    On your content slides you select the master slide in the Properties panel, general, master slide dropdown.
