I use the web (ie free) edition of Alteras FPGA IDE. According to the documentation, it hosts at least some of the Altera megafunctions. A response to an earlier tech forum enquiry indicates that it does.
I’ve tried to use them, but without success. When I ‘create’ an instance using the Altera Megafunction guide, all that comes out is something like a ‘pure virtual function’ for a COM object, ie. a function prototype / data structure. I can’t seem to be able to actually instantiate a working function, and can’t find any actual working Verilog code. It would be great if someone could point me to some information that might help.
Specifically, if using megafunctions, is code created in an accessible form such as Verilog, or is the functionality in the form of a netlist or some other non-user-accessible format?
Megafunction is softcore and hardcore IP, and It is not accessible as verilog code, at some level u can see. but can't able to decode full IP core RTL.
Yes!, it is some other non-user-accessible format. click here for megafunction import procedure.
This document might help you : Altera Doc it is about RAM megafunctions but there is some informations about how to instantiate a megafunction (ie page 24/64)

My understanding is that AEP can be developed in any language but I couldn't find any sample for VFP, only VB, C++, etc
As an initial project I wanted to try something simple like send a Product Code and get back the current Stock value from a free ADS table (in fact a VFP table accessed via ADS) + errors handling.
I have good VFP experience (exe applications using ODBC) but nothing in this area (web access).
I made some researches on internet but even for the Startup/Shutdown (part of the template) I found different number of parameters to be passed, so I am confused.
A sample of Startup/Shutdown + a simple function which access a table and get some data (i.e SELECT Field1 FROM MyTable WHERE Field2=<My_Input_Value>), written in VFP for ADS V10.10 would be highly appreciated.
Thanks.
I'm having an Issue with a blog extension in Magento CE 1.6.2.0.
I installed this extension: Neotheme_nBlog.
I created an entry in the administrator.
Then I went to http://www.example.com/index.php/blog/ to see the recently created entry.
What I saw was an error like this:
Fatal error: Call to a member function getName() on a non-object
in /home/example.com/public_html/app/design/frontend/default/caramel/template/magicat/left.phtml
I searched in google the terms: "template/magicat/left.phtml" getName and what I only found is sites having this issue, but no support at all.
Please note: I know what does that error mean in PHP ("unfortunately" I'm not new at that). What I don't understand is what's happening with such [NON/null] object and how to fix it without killing a dozen of kittens.
Question: What can I do to solve it? What is the nature of the error, regarding Magento?(again: not PHP).
Notes: The Magento site (http://magento.stackexchange.com) is somewhat poor and strict to bring support of such nature, so asking there is not an option.
Edit (as answer to comment, and to clarify):
Neotheme is still not responding the request.
Don't know what should I look on such file (instances are not initialized there, but only accessed).
I'm using the default theme (caramel), which has esthetical changes (does not have layout changes).
It's hard to say without seeing your system specifically, but on this
template/magicat/left.phtml
It looks like you've added a template named magicat/left.phtml to your system -- either via an extension or custom development. Somewhere in this file PHP's called getName on a non-object. There's a variety of reasons this could be happening, and without seeing the specific line of code PHP's complaining about in your system, it's hard to say. It'd also be helpful to know if magicat is part of the extension or something else.
The most common reason for this error in a template is code that relies on a block being there that's been removed by another extension (eitehr via layout XML or observer methods)
$this->getLayout()->getBlock('some_block')->getName();
The next most common is people using the registry to communicate between templates and views, but a registry key not being set
Mage::registry('some_item')->getName();
Without knowing the variable and context, it's doubtful anyone will be able to help you.
The global VB6 error handler product referred to in the following link claims to "install a small callback hook into the VBE6 debugger":
http://www.everythingaccess.com/simplyvba/globalerrorhandler/howitworks.htm
I would like to implement this product myself because I would like more control over what it is doing. How is the above product likely to be achieving what it does?
The product you are looking at is a COM component. From the documentation that is available on the web site, it sounds like the COM component implements particular component classes. The first thing to do, if you already have the product, would be to fire up SysInternals procmon, run regsvr32 on the DLL, and figure out what component classes are implemented from the registry entries that are created. Once you know this, MSDN may be able to tell you what interfaces correspond to those component classes.
Microsoft developed a framework called Active Scripting that allows you to host a script engine and inject debugging capabilities. If one assumes that VB6 produces an exe that ties into that framework, you might be able to do:
Create a COM component that implements IApplicationDebugger
Implement IApplicationDebugger::onHandleBreakPoint to be able to respond to errors in the VB code
Read MSDN KB Q222966 to find out how to call back to VB from onHandleBreakPoint
It looks like the product injects the ErrEx class using IActiveScript::AddNamedItem. To provide the same behaviour, Implement IActiveScriptSite::GetItemInfo on the same COM component to return a pointer to an instance of (and the associated TypeInfo for) a COM component that implements the same interface as ErrEx. In your implementation of ErrEx.EnableGlobalErrorHandler you would do the following:
CoCreateInstance inproc Process Debug Manager
Cast reference to IRemoteDebugApplication
Register an instance of your IApplicationDebugger component using IRemoteDebugApplication::ConnectDebugger
I glossed over calling IActiveScript::AddNamedItem because I have no idea how you get a pointer to IActiveScript from a running process. Also, I don't know if creating a new instance of the Process Debug Manager will work, or if you somehow have to hook into an existing instance.
I apologize for the confusing explanation, missing information, and glossing over large parts of the process, but this is going waaay back...
You will want to read the Active Scripting APIs article at MSDN.
Like the title says, i want to disable images, and ActiveX Controls in the vb6 webbrowser control using DLCTL_NO_RUNACTIVEXCTLS and DLCTL_NO_DLACTIVEXCTLS
Microsoft talk about it here: http://msdn.microsoft.com/en-us/library/aa741313.aspx
But i dont see any way to access IDispatch::Invoke from the vb6 application.
Any help would be greatly appreciated.
I do not think VB6 let you to add the ambient properties. Try host the ActiveX in another container (e.g. an ActiveX host written by yourself - but I do not know how much time you want to invest to declare VB-friendly OLE interfaces and implement them - or use another ActiveX like the one at http://www.codeproject.com/KB/atl/vbmhwb.aspx instead.
You don't access IDispatch::Invoke in VB6, you just write you method and IDispatch is automagically implemented.
Public Function DlControl() As Long
DlControl = DLCTL_NO_DLACTIVEXCTLS Or ...
End FUnction
Then just open Tools->Procedure Attributes and for DlControl function open Advanced and assign Procedure ID to -5512 (DISPID_AMBIENT_DLCONTROL). That's first part.
Second part is to set the client site to you custom implementation of IOleClientSite. You'll need a custom typelib, try Edanmo's OLELIB for declaration of these interfaces.
Here is a delphi sample how to hook your implementation of IOleClientSite. Apparently you'll alse have to call OnAmbientPropertyChange at some point.
I'd like to apply the MVC pattern to a GUI we are developing for an embedded system. In this case my understanding is we would need to provide the underlying framework for listener/event actions between the Controller and View. Also, I have seen some examples where the Model send an event to the View, but perhaps that is not correct. Does that seem correct?
Does anyone know of a framework targeted to embedded devices that may have this capability?
If your embedded device supports Java, eRCP would be the best GUI framework in that case.
Check out: http://www.eclipse.org/ercp/
Model sends event to view is a way to notify the view updated about things has been changed in model. It's normal communication between M & V in MVC. However, the "view" here should be a generic view which is bound via an "observable" interface, not a concrete one.
For example:
Abstract View: Clock (generic interface)
Concrete View: Digital Clock, Analog Clock <--implementation of Clock
Model: Time <-- "knows" Clock but not Digital or Analog...
I could suggest the Qt Toolkit. But you don't give any mention of your platform capabilities.
If you are working on a linux platform. Try Enlightenment the best GUI I have ever seen.....
