Questions regarding visualforce

Questions regarding visualforce. I post a thread on the discussion board but do not get good feedback.

I have a multipicklist custom field which has ten values and  I want to display this custom field as checkboxes on the VF page. Now I use apex:selectCheckboxes tag, but the result is all the ten checkboxes are in one line(I don’t find any attribute on this tag to limit the numbers per line). Is there any way to display only three checkboxes in each line?

Now:

box 1 box 2 box 3 box 4 … box 10

I want:

box 1 box 2 box 3

box 4 box 5 box 6

…..

box 10

 

Another question is that currently I am using tabpanel and each panel is a Visualforce page. So when I click the panel, I want to go to a different vf page.  I try to add javascript code 'windon.location = PAGEURL' in onclick event, but it does not seem to work. Can you give me some suggestions? Thanks!

Can I sort the data by the value in field priority?

I want to sort the data by the value in field priority. There are three values in that picklist field: High, Medium, Low.

 

If I only fire the query select XXX from Case order by priority. The result I get back will be High->Low->Medium (by letter order). But what I want is High->Medium->Low (based on the meanings). Are there any way I can write the SOQL to achieve this? Thanks!

Questions about keyword 'with sharing'

Hey, currently I ran into a problem that when I use the query [Select acr.Role From AccountContactRole acr where acr.AccountId = :userContact.AccountId and acr.ContactId = :userContact.Id] in a class with the keyword 'with sharing', it says: no such column Role in Object AccountContactRole, if I fire the query in a class without the keyword, it works fine. 

 

I am wondering do with sharing provide object level security or also field level security? thanks!

The latest Force.com IDE doesn't work

Hey,

 

Recently, I install the Force.com IDE plug-in for eclipse, but there are some problems. My eclipse version is Ganemyde, force.com IDE version is 16.0. After refreshing files from server (I have 30-40 metadata files), every five minutes, my IDE becomes extremely slow, after sometime it says Internal Error: Out of Memory. Do you like to exit the IDE? I don't know why this will happen like every 5-8 mins. Any idea?

How to return binary data from an External web service callout (HttpRequest)?

Can anyone tell me if  it is possible to get binary data back from a web service callout?

 

I am using the apex Http, HttpRequest and HttpResponse classes to call an external  service that returns a binary file. I then attach that file to an email programatically. Everything works fine, except that my binary data in the attachment is mangled, because of the string conversion on response.getBody(). Is there a way to retrieve the binary stream from the HttpResponse class without corrupting it? 

 

Or is there another set of classes I should use to perform this function to get the results I'm looking for? 

 

Thanks for any help!

Gretchen
