Unable to open local files from Internet Explorer window? IE6 SP1 and later

2010-02-11T21:35:00.000-08:00

Symptom
Problem opening up local files in a Internet Explorer window. For example, the following code works on some systems and does not work in some.

Test

Explanation / Workaround: from Eric Shen [MS]

The issue is a new security feature in Internet Explore 6 Service Pack 1. In order to prevent Internet vicious codes from accessing your local files, the development team developed the new security feature and included it in IE6 SP1. Please be advised that this is a normal behavior. Actually, IE6 SP1 includes new security code checks that prevent "zone elevation". This means that documents located in the "Internet" zone will not be granted access (through HREFs, scripting...etc) to documents in the "My Computer" zone. Only documents located in the "Trusted" or "My Computer" zone can access documents in the "My Computer" zone. Therefore, if you want to allow untrusted documents to access documents in the "My Computer" zone, you might add the source URL in "Trusted sites" (this must be done with caution for obvious security reasons). The "Local Intranet" zone is trusted as well.

Furthermore, the following registry key allows disabling the new security codes check that prevent "zone elevation": - You can create this DWORD key and set it zero to disable this new feature. Also, you can enable it by changing it to 1 at any time.

HKCU\Software\Microsoft\Internet Explorer\Main

Disable_Local_Machine_Navigate = 0 (REG_DWORD)

It is not recommended to use above registry key since it breaks the "zone elevation" security fix. Please use this tweak only if you have a valid reason to do so. The above is a per-user setting.

(XP Service Pack 2) Local Machine restrictions prevents even the Trusted sites from opening files in My Computer Zone
In Windows XP Service Pack 2, no site from any Zone can open files in local machine zone, whereas in pre-SP2, only Internet Zone sites were restricted to open local files, while Trusted/Intranet can.

While the above method (Disable_Local_Machine_Navigate) works fine in Windows XP Service Pack 2 also, here is more information and another workaround for this issue:

Security Zone value 2101 corresponds to URLACTION_FEATURE_ ZONE_ELEVATION
Description: Web sites in less privileged Web content zones can navigate into this zone.

"Tweak" or alter the Lockdown Zone template itself:

Disabling this restriction still breaks the "Zone Elevation" security fix. Use only for valid reasons.

Open Registry Editor and navigate to:

[HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Lockdown_Zones\0]

Backup the key to a REG file and in the right-pane, set the value 2101 to 0

Using Image in Ajax.Actionlink of ASP.NET MVC

2009-09-01T18:08:00.001-07:00

To use image instead of text in Ajax.Actionlink is not possible directly so we have to user indirect method for it.

Using Direct image

< %= Ajax.ActionLink("[Add]", "About", new AjaxOptions { }).Replace("[Add]", "< [img] src = \" ../../Content/add.jpg\ " alt = \"image\" / >" )% >

Using div

[< %=Ajax.ActionLink("[Add]", "About", new AjaxOptions { }).Replace("[Add]", "< class ="\">< /div >")% >]

Checking file type with javascript before uploading

2009-08-31T18:48:00.001-07:00

Limit the types of files users can upload
The following JavaScript function can be used to validate that the type of file that a user tries to upload is of a certain format. It does this by checking that the files extention (eg .html) is in an array of allowed extensions that is passed to the function as an argument.

< type="text/JavaScript">

< !-- Begin
function TestFileType( fileName, fileTypes ) {
if (!fileName) return;

dots = fileName.split(".")
//get the part AFTER the LAST period.
fileType = "." + dots[dots.length-1];

return (fileTypes.join(".").indexOf(fileType) != -1) ?
alert('That file is OK!') :
alert("Please only upload files that end in types: \n\n" + (fileTypes.join(" .")) + "\n\nPlease select a new file and try again.");
}
// -- >
< /script >

You can test it using the file upload below which will only accept image files that end in either .gif, .jpg or .png:

You can then call the function from an event like the onClick of the above button, which looks like:

onClick="TestFileType(this.form.uploadfile.value, ['gif', 'jpg', 'png', 'jpeg']);"

or, alternatively, you could put it in the onChange event of the file upload element.

Note that the above example assumes that you know the "name" attribute of the file upload element. In domino R5 you can do this to an upload by putting a name in its HTML attributes. In R4 you cannot do this so you can either create the upload yourself by using the following pass-thru html

Otherwise you would need to loop through all elements on the form looking for any input of type "file" and then validating this. This method is demonstrated here.

Note: This is not entirely foolproof as people can easily change the extension of a file before uploading it, or do some other trickery, as in the case of the "LoveBug" virus.

Get Dynamic Thumbnail for you site

2009-08-30T11:00:00.000-07:00

I implemented a new feature over at my Jenny McCarthy and Hayden Panettiere websites this past week.

I've been posting YouTube videos on both sites for quite some time, but have only been providing text descriptions to go along with the links from the main video pages. I finally decided that I wanted to figure out how to dynamically include thumbnail image previews of the clips, not only to display on the main video pages, but also in web feeds where applicable.

First I got all fancy and was sending in YouTube API requests to get at the information. The youtube.videos.get_details function provides thumbnail information in its node.

However, once I had implemented a preliminary approach using that method, I quickly realized there was a very obvious pattern to the thumbnail URLs being returned with each call:

http://img.youtube.com/vi/LiIboq6XCOg/2.jpg

The only portion of the above URL that seems to change is the video ID between the fourth and fifth forward slashes.

So rather than calling the API multiple times to get thumbnails for all the videos presented on the page, I decided to keep all function calls local, opting to create my own internal function for extracting the YouTube video ID from my XHTML-compliant embed code using a regular expression and then inserting that between the http://img.youtube.com/vi/ and /2.jpg portions of the static thumbnail URL.

The result is much faster and works like a charm.

Creating branch in SVN

2009-02-18T02:56:00.000-08:00

Creating brach with command prompt
creating the branch
1. Note the current head revision:
svn info svn://server.com/svn/repository/trunk grep Revision
2. Make a clean, remote copy of trunk into the branches folder. Name it something. We’ll call it your_branch:
svn cp svn://server.com/svn/repository/trunk \
svn://server.com/svn/repository/branches/your_branch \
-m "Branching from trunk to your_branch at HEAD_REVISION"
Replace HEAD_REVISION with the revision number you noted in step 1.
Note that a backslash (\) means that the command continues onto the next line.
3. switch your local checkout to point to the new branch (this will not overwrite your changes):
svn switch --relocate \
svn://server.com/svn/repository/trunk \
svn://server.com/svn/repository/branches/your_branch
You don’t really need the --relocate svn://server.com/svn/repository/trunk bit, but I’m in the habit of being explicit about it.
4. Check that your local checkout is definitely now your_branch, and that you can update ok:
svn info grep URL
svn up
5. commit your new changes.
(These steps will work even if you had already made local changes on trunk, but decided you wanted them on your_branch instead. If your trunk checkout was unmodified, just skip step 5.)
updating the branch
You’ve been developing for a while on your_branch, and so have other people on trunk, and now you have to add their changes to your_branch.
1. First, update your branch checkout and commit any outstanding changes.
2. Search the Subversion log to see at what revision number you last merged the changes (or when the original branch was made, if you’ve never merged). This is critical for making a successful merge:
svn log --limit 500 grep -B 3 your_branch
3. Also note the current head revision:
svn info svn://server.com/svn/repository/trunk grep Revision
4. Merge the difference of the last merged revision on trunk and the head revision on trunk into the your_branch working copy:
svn merge -r LAST_MERGED_REVISION:HEAD_REVISION \
svn://server.com/svn/repository/trunk .
Replace LAST_MERGED_REVISION with the revision number you noted in step 2, and HEAD_REVISION with the revision number you noted in step 3.
Now look for errors in the output. Could all files be found? Did things get deleted that shouldn’t have been? Maybe you did it wrong. If you need to revert, run svn revert -R *.
5. Otherwise, if things seem ok, check for conflicts:
svn status egrep '^C^.C'
Resolve any conflicts. Make sure the application starts and the tests pass.
6. commit your merge.
svn ci -m "Merged changes from trunk to your_branch: COMMAND"
Replace COMMAND with the exact command contents from step 4.
Phew.
folding the branch back into trunk
Hey, your_branch is done! Now it has to become trunk, so everyone will use it and see how awesome it is.
This only happens once per branch.
1. First, follow every step in the previous section (“updating the branch”) so that your_branch is in sync with any recent changes on trunk.
2. Delete trunk completely:
svn del svn://server.com/svn/repository/trunk
3. Move your_branch onto the old trunk location:
svn mv svn://server.com/svn/repository/branches/your_branch \
svn://server.com/svn/repository/trunk
4. Relocate your working copy back to trunk:
svn switch --relocate \
svn://server.com/svn/repository/branches/your_branch \
svn://server.com/svn/repository/trunk

Creating branch visually with VisualSVN
- select "VisualSVN->Branch" in the Visual Studio main menu, - enter URL like https://myserver/svn/myproject/branches/new-feature - check "Switch working copy" at the bottom and click OK, - commit your unfinished changes to the branch
- select "VisualSVN->Switch" in the Visual Studio main menu, - enter URL of the trunk folder (https://myserver/svn/myproject/trunk) - implement urgent fix and commit it to the trunk,
- select "VisualSVN->Switch" in the Visual Studio main menu, - enter URL of your branch (https://myserver/svn/myproject/branches/new-feature) - continue working and committing subsequent changes to the same branch,
When the work is finished: - select VisualSVN->Switch in the Visual Studio main menu, - enter URL of the trunk folder like https://myserver/svn/myproject/trunk and click OK, - select VisualSVN->Merge in the Visual Studio main menu, - select "Reintegrate a branch" - enter URL of your branch and click Next, Merge - after merge is completed you might want to review your changes, - commit merged changes to the trunk.

What is OpenID
OpenID is a new concept which lets a person to maintain his identity same over the internet. With OpenID a person doesnot need to register in each and every sites in the net. He/she just need to register to a OpenID provider. OpenID works in many sites that support OpenID. This concept is very easy and simple.

How does OpenID works ?
OpendID works in a simple way. First a person needs to register to a OpenID provider of his/her choice or even he/she can maintain one for himself/herself. When you need to visit a site that support OpenID but you are not a member to it then you dont need to register to it. Just provide your OpenID. Then the site takes all the necessary information from the OpenID provider and you can login. Dont need to register to different sites and not to worry about different usernames in different sites.
For more detail see the video.

Programming At A Glance

2008-08-26T09:47:00.000-07:00

What is programming ?

In my terms programming is life. You become programmer a good one if and only if you have passion to do it. You don't become a good programmer unless you have that feeling for programming. You need to think different.

Programming is not about knowing the syntax of every language. But knowing the ways to do it. You need to know the algorithm and be able to develop one by your self.

Programming is life and life is all about programming
