I'd still like my users to have a choice of image to select when sharing links from my site but I would like to restrict certain images from showing in the Facebook sharer. I don't want to select a specific image using meta tags (this has been suggested often).
Would appreciate any help!
EDIT (9 Jul 2012): This question is not an exact duplicate to any others on stack overflow. I asked for a method to restrict images from showing without specifying OG or meta tags, unlike others who have simply asked how to show a specific image. Why do people on this site assume (and rate my question down) before even reading it carefully and considering whether it is a duplicate.
The only way to do this is to specify multiple og:image tags of images that you want to allow and then the user will be able to choose from the images you select.

I would like to hide certain posts on my tumblr homepage that have the a specific tag (#journal). I've already tried some codes, but it didn't work.
Here is my actual HTML code:
pastebin.com/JT4KtyVz
My tumblr:
http://heynotspecial.tumblr.com/
Do you guys know how to do that?
Sorry, not used to post code here :(
You need to identify a commonality for posts that have the Journal # tag. I suspect there could be a class name applied to posts with this tag.
You can apply this rule in your CSS stylesheet to hide div elements with the infscrjournal classname.
{block:HomePage}
div[class~=infscrjournal] {
display: none;
}
{/block:HomePage}
**** you need to surround the code with the homepage variable to make sure it only appears on the first page and nothing else. Try that

What is the code for displaying picture in Visual Foxpro 6?
Does anyone know the codes for displaying a picture that is found within a Column in a table using Visual Foxpro 6?
My project was Library System, that includes the time in and time out of the librarians and students. And needs to upload a picture of students together of their information in the registration.
Example:
If a student enters the Library , he/she needs to swipe his/her ID to login or time in and his/her information will appear on the computer of the admin. Same process when he/she leaves the library . . . he/she needs to swipe his/her ID then logout / time out.
I think your question is vague and misleading based on other answer provided. What is SOUNDS like is that you have a database of teachers and students (much like a membership as a gym or similar). For each record in the database, you have an image file associated with that person. The image may be part of the actual table, or just a file name that is pointing to a specific directory on your drive share, where all the people images are available.
From that, these people have ID cards and when they enter a given facility (your Library for example), they run their ID card through a reader. At that time you are doing a search from your network database of users, find the user and pull up the image to the screen to show who the person is to help prevent fraud of someone using somebody else's ID card. This allows the person monitoring the entry area to make sure that Jim is not using "Bill's ID card to gain access.
If this is the case, and your VFP app is already running and ready to read from the card reader, you should only need to add an image file to your screen for presentation somewhere. Then, based on your finding the appropriate ID, get the record, analyze (if part of the record or just file name in a given images path), get the image file and set the property on the image control to point to the correct image. Then, do whatever logging update that states that Bill just entered the facility.
-- update per comment --
Jenna, I don't know how the original records were added to your table, and it sounds like you were handed this project. The column type within VFP is that of a "General" field. Somewhat like that of a memo field that can also hold binary data, the General data type is more for Object Linking and Embedding (OLE) content. It appears that when users were storing the values, they were adding as a linked or embedded content via something like
APPEND GENERAL YourPictureColumn from SomePath\SomeFileName.bmp
check the syntax under VFP 6 for "APPEND GENERAL". You can also state how via a LINK to the actual file vs EMBEDDING by having the actual image included so if the original source is removed, you still have it in the file.
As for the "picture frame" you see when you double-click this column, it is because VFP does not know how to properly interpret the image, such as as "MS.Paint" class object, or "Picture", or whatever. I've never really liked doing General fields, but would instead have a memo field with just the name of the full path/file name of the image I was keeping and had a separate folder to just stick all the image files. Then, when I needed to show that specific image, I would change the property of the image object on the VFP form to that location.
Now, if that is a route you might like to go with, I'm not exactly sure out to extract those image files, but can look into it more.
As for testing the concept of the image sampling, in VFP, make a new folder for a sample form.
Copy in the folder a few images to sample.
Create a simple table with 2 columns...
CREATE TABLE MyPicSample ;
( PersonName c(10),;
ImgSource m )
Add as many records as images you copied to the test folder. For each, put the file name of the images (full path) into the "ImgSource" memo field, and a sample description for the "PersonName".
Next, create a form, open the data environment and add the "MyPicSample" table just created.
Drag this table from the data environment to the form and it will create a grid on the form. Resize it some you only need a small amount of space to show the one column for PersonName. Close the data environment.
Add an "Image" control to the form. It should default the object name to "Image1"
Double-click on your grid to bring up its code snippet window and then double-click on the "AfterRowColChange" event... paste the following over it..
LPARAMETERS nColIndex
Thisform.Image1.Picture = MyPicSample.ImgSource
Save and run the form. As you scroll up/down the grid, you should see the image change to the respective BMP/JPG file.
I think this is the concept of what you want, but instead of a data table grid displayed, you will be doing this from a scanned card that gets a record, has an image and then present THAT image (now in a General data column type).
Again, not sure how you have your images via embedding or linked, but with this, we can probably get going closer to your end-result needed.
Depends on where you need to upload the image to.
If you are uploading via FTP, you should be able to use the following snippet in Foxpro. It's utilizing the Internet Transfer Control.
inet = CREATEOBJECT("inetctls.inet")
inet.Execute("ftp://ftp.microsoft.com", "CD DIRNAME")
inet.Execute("ftp://ftp.microsoft.com", "PUT LOCALFILE REMOTEFILE")

Question: Are there any Mvc framework solutions that I can leverage to create a clean and concise approach that represents my user control that I am converting? (There are four major design considerations listed below)
This user control has a lot of explanatory text information within. I really want to avoid writing a helper method that is a mile long containing a ton of standard HTML and text.
This user control contains a Grid. I have written my on Grid control in Mvc but I have not had any experience as of yet with composition of html helpers in a clean fashion.
This control is only presented to the user as a result of uploading a spreadsheet for importing purposes.
The design needs to account for being in a standalone dll that is used in other projects.
I was considering the idea of using a Partial View. This would be preferable since it could make calls to the html helper to render my grid and contain the explanatory text.
However, I couldn't find examples online that really lent themselves to my scenario. So I not confident of the details.
Thanks for input in advance.
Explanatory text can be stored in a view model. It'll be stored in a
single place and it can easily point to a resource file with
localization (if needed)
Re-factoring. I can't get into more details as I haven't seen the code
If you opt-in for a partial view, you can render control with #Html.RenderPartial, #Html.EditorFor, #Html.DisplayFor depending on what kind of control this is. In my project I have controls for storing and displaying search criteria. So I have something on the lines of
#Html.EditorFor(model => model.CategorySearch, "CategorySearch")
I'm not sure about a seperate DLL, but if you have a clear seperation between a view and domain model, then you should be able to get away with copying your view model and view related components (e.g. partial view, editor/display templates etc)
I hope this helps

I have been searching the internet for days now trying to find out how to write my own script, one more complicated than the "Hello World" script.
I understand for the most part how to find specific elements using firebug (I have Firefox). I understand the metadata and how to do all that.
I do not however understand how I am supposed to get whatever I want into the page. Be it links or tabs for Facebook or other sites.
Can anyone help me get a full tutorial/guide that is up to date and easy to understand for total scriptwriting beginners?
From what you have described in the, I suspect that anything that meets your criteria will actually just be a Javascript tutorial with some extra Greasemonkey-specific sections / focus
There's not links to many guides and tutorials (might add them in later) but I really think that what you need is a beginner's guide to Javascript such as sections 1-8 (except 5) of the one provided at the Mozilla Developer Network.
Greasemonkey stuff:
Specifically, the Greasemonkey-related topics that you will need to read up on are related to the DOM, altering styles of DOM nodes, and the Greasemonkey API. All else that you need will be generic Javascript that will be specific to the script you are creating.
DOM Manipulation:
Inserting / editing / deleting "nodes" ( in the HTML code) - for example, <a>nchors, <div>s, <img>s
This is how the extra links and tabs etc are added into the page.
Specifically, look into appendChild(), createNode() and insertNodeBefore().
DOM Traversal
Moving around the DOM (HMTL Document) and selecting where to insert the new nodes / selecting which nodes to editor delete.
Specifically, look into XPATH, getElement(s)By_____, parentNode, querySelectorAll()
Introduction to using XPath in JavaScript - XPath | MDN
Node.parentNode - Web APIs | MDN
CSS Using Javascript
The basics of changing the CSS of a node are to either use .setAttribute() to set the 'style' attribute, or to alter specific CSS properties using nodeReference.style.cssAttribute = 'value'.
Greasemonkey API
Again, this stuff will be specific to what you want to use within the script you create but the basics include GM_getValue(), GM_setValue(), GM_log()
Greasemonkey Manual:API - GreaseSpot Wiki
Look at Greasemonkey Hacks archived, especially the part Avoid Common Pitfalls archived - I'm often returning to the latter.
Edit: the original links are dead, added links to recent archived version in superscript.

This can be applied to any language/UI project. When the code is automatically generated, is there a need to name all of the UI controls? Presently I only name the ones I am referencing in code (although admittedly sometimes I get lazy and leave them). Or do you stick with the pre-generated names (textbox1, splitContainer1, menuStrip1, etc..)?
If you name them, how do you prevent overlap such as MyDataGridView1, MyDataGridView2, etc..
I only name the ones I reference too - most modern IDEs will easily rename a widget later if I need to reference it in code.
I usually give the names some meaning - accountDataView, currentBalanceDataView - it must relate to a concept like submitButton for the button that submits a form.
I always try to set GenerateMember to false for the controls I don't use in the code, but for the controls I do use in code, I usually choose meaningful names.
For example, if there was a button that submitted something then I would choose submitBtn. If there was a username textbox then I would call it usernameTxt. Etc, etc.
A small list:
Buttons: btn
Textboxes: txt
Labels: lbl
Checkboxes: chk
Radio buttons: rad
List boxes: lst
Dialogs: dlg
...but above all else, just use what makes sense.
I name the controls that I access and have experimented with using the "ux" prefix so that I can find them easily with Intellisense. That way if I can't remember the exact name of a control I know it at lease starts with ux. Also, if I change the control type, the name can stay the same. I came across this a while back, but can't seem to find the article about it now.
