I need to create attachment that can be downloaded clicking on a link how to do it in salesforce
You can implement it with Visualforce page and controller.
On VF page you need to use something like:
{!attachmentInstance.Name}
And in controller you can use SOQL query to Attachment object, like:
List<Attachment>attch = [Select Id, Name from Attachments];

Assume a URL link (containing a merge field on the Account object) exist on the Account object with the API Name link_1, and I have a VF Page with a standrdcontroller on Account, is there a way to call link_1 from the controller or when the page loads, the goal here is to invoke that link programtically once the controller and action are completed.
And what do you mean by invoke? Redirect user to that linked page? Pull that page's content and somehow display? Get page's content, save to PDF and put in Attachment in Salesforce for example?
Actions that can be bound in Visualforce are supposed to return PageReference. Most of the time you return null or mark the method as void, you want to stay on current VF page (maybe there's something else you want the user to do, maybe there were errors and you want to display them on same page so user has chance to fix them). But for you it could be
public PageReference doSomething(){
// Your action code here
// ...
PageReference pr = new PageReference(acc.Link_1__c);
return pr;
}
I have two vf pages, say vf1 and vf2, which have standard controller for same object say Leads. Now i want to show vf1 page for edit button for any profile1 and and vf2 page for profile2 on edit button.
Tried to see any option in Profile menu, but not able to find anything for page assignment for list/edit/create/...etc. for an object.
There is no such feature in Salesforce to allow visualforce page assignment per profile.
I would recommend below
1.Create a hirerachy custom setting to store the mapping between the vf page and the profile .
2.Write a vf that will be assigned for all profiles but on action (called upon where page loads) it will look into the hirerachy custom settings map and takes the user to right visualforce page .You can pass along page parameters as query parameters .
When I Press the Save button it saves the values but when I hit F5 or refresh; the values are gone, they are not visible on my VF page.And for this :
I have created VF page with standard controller and extensions.
created one controller.
And I have embedded VF page into Opportunity object.
Any idea how I can achieve this ??
Thanks.
The description is not very clear to me. What my understanding is you have a VF page with Opportunity standard controller with extension class. This page has a form which works when you save, but when whole page is refreshed the values are gone.
If my understanding is correct than here is a solution that you can try. For standard controllers to get data they need record id you can pass it through url like this:
http://na1.salefroce.com/apex/yourVFPage?id=
Now in your extension you can use following method to get the record:
public Opportunity opp;
public myControllerExtension(ApexPages.StandardController stdController) {
this.opp = (Opportunity)stdController.getRecord();
}
Now you have record values in the opp variable, you can use this to display values as long as id parameter is passed. You can populate this variable by using SOQL as well.
Really new to VF, but here's my VF page. the desired effect is that i want it opened up in a new tab in the same window.
<apex:page standardController="myController__c" extensions="myExtension" action=" {!actionJackson}">
</apex:page>
If your overriding a standard VF page in SFDC your halfway there, it looks like your trying to reference a standard controller of a custom sObject called: 'myController__c', kind of a weird name for an object but if you want to import the standard controller use your objects name as the standardController.
If your custom sObject that you were trying to create a new VF page for was called: "myObject__c" than your page definition would look like:
<apex:page standardcontroller="myobject__c" extensions="class1"></apex:page>
Now go (using the web-ui):
Your Name->Setup->Create->Objects->myObject__c->Standard Buttons and Links->Edit 'View' (lets say you wanted to replace the 'View')
Now choose to override with a VisualForce Page and select the name of your page from the drop down.
Now following the link to view a record in SFDC standard layouts will take you to the new custom vf page. The same goes for edit (if you override it).
Now all you have to do is follow the instructions on SFDC for using and extending the standard controller or standard list controller.
I'm writing a VisualForce page to replace an old legacy S-Control.
Originally the Custom S-Control was launched from a Custom Button, and it opened in a new browser window (The S-Control is type HTML, and the Custom Button has Behavior: Display in new window)
For certain old records, I want to do a similar thing from VisualForce.
So: Do HTML S-Controls have a URL that I can launch using a link? In which case, how do I figure out the URL?
Or:
Is there a way of embedding 'Custom Buttons' (that is, the buttons defined in "Setup->Customise->Account->Buttons and Links") into VisualForce pages? If so, I can embed the existing button that knows how to open the S-Control
Or:
Can you suggest some other way of doing this? Key features: Open an S-Control in a new window from VisualForce.
Thanks
Got an answer from this forum post courtesy of aballard:
Basically, the !Urlfor() function can be used to get the URL of an S-Control. So, you can use an outputLink like this:
<apex:outputLink value="{!UrlFor($SControl.my_scontrol_name)}"
target="_blank">Show SControl</apex:outputLink>
If you need to pass an object ID to the S-Control, you can add a second parameter that calls a propery on the custom controller, e.g:
<apex:outputLink value="{!UrlFor($SControl.my_scontrol_name, AccountID)}"
target="_blank">Show SControl</apex:outputLink>
... where AccountID is defined on the custom controller as public string getAccountID()
