Sorry - but I was cranking out code at 10 past 1 this morning, so I feel properly self-righteous.

Here is some xaml that will animate an ellipse across the text...basically using visual brush to set the fill property of a TextBlock. Then I animate the Left and Top property of ellipse contained in the visual brush. Since a visual brush can be anything you could put image or video here also, basically any visual you want. Enjoy...

Well I suppose that you could click on the button with a mouse like everyone else.... 
What is it exactly that you are try to do?
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

My purpose has been changing the Mouse States styles !

Ah, then you should look at how to add Triggers to your style for the MouseEnter, MouseLeave, etc events

Hi all,
i'm a new one in Wpf and i like it so much ,i'm studying and learning about WPF from one month and from 5 months i 'm studying about programmer so i'm poor of knowledge and experience.
I will develop a project within 2 or 3 months in my companyWork and so i will ask some advice about the right software,tools and else to develop in easy way(it's only way that i can run now).
I will give you more precise details ,the project will be based on a Big database on a server and after i will create a application (multithreading) where employees can connect to the database and Add,Delete,Edit the database everyday then i will use many DataGrid so to develop this database i been studying about these software:
- SqlServer _to develop the database
- NHibernate _as Orm to mapping the Database
-WPF _for graphic interface and else...
now i'm in doubt and confuse too,NHibernate is a great ORM but not so friendly with WPF (i saw some news about that) as they are not so easy to use (for me) so i will ask you some useful idea to help me to develop my future project in right way .
Thanks so much for your attention .
Any kind of comments are useful to understand better .
Bye

I'd say start with something smaller and simpler.
Make a small desktop application that mirrors the sort of functionality that you are looking for.
1. Make a simple SQL Compact database.
2. Use SQLMetal.exe to produce a dbml file from the database
3. Write a small simple WPF app that allows you to work with this database.
ORM bears no relation to WPF as far as I know. ORM is a process of mapping databases to CLR objects irrespective of the UI technology slapped on top of it all.

Hi Jammer,
thanks to reply me i will follow your advice, i don't know where download SqlMetal.exe as never i used it i will try better to search it.
I already done a project using NHibernate with WPF and a database with SqlServer .I got a trouble when i should populate a DataGrid with NHibernate i couldn't delete and edit a record (but i think it is fault of my knowledge) i used also M-V-VM as pattern i like it but i fell confuse because i learn everything so fast instead i like understand in depth.
After i will try try SqlMetal.exe as you advice me.
If you have other advice you can tell me everything to refresh my mind.
Thanks for your kindness
Have a good time.
Bye

Hi,
SQLMetal is part of the Windows SDK (get v6.1) from Microsoft. Its an ORM mapper for SQLCE as most of the NHibernate et al don't cater for SQLCE and VS GUI ORM doesn't work with SQLCE.
Cheers,

Hi Jammer,
i downloaded SqlMetal and it is a great tool,thanks for your right advice
now i'm practising with Linq and with a SQlServer to populate a DataGrid do you know some link where i can learn to do it right??
Have a happy time
Cheers

1. Create your dbml
2. Read in some data from the database into the domain objects built by sqlmetal
3. Read that data into an ObservableCollection
4. Bind that ObservableCollection to your grid
|
|
|
|
|
Thanks again,
i will follow your way if i will meet some difficult i will create a new post to ask help.
THanks so much SqlMetal is so nice
I wish you happy day.
Bye

No problem.
One tip ... when using SQLMetal I generally tend to also create a batch file with the commands in so that if the database scheme changes you can be assured that recreating the LINQ context the classes will be built with the same parameters.
|
|
|
|
|
Sorry Jammer
how i can create a batch file in the project?With SqlMetal?
Thanks for your support.

Hi,
I have a WPF application. We have a requirement where in user can add/edit a document to the Share Point document library from the WPF Client application. Using Front Page RPC we are successfully able to add the documents to the Share Point document library. After successfully uploading a document to the Share Point doc. library, an entry is made in the database which stores the File Name, SP File URL etc.
To accomplish the EDIT functionality, we show a list of all the docs (from the DB) which were uploaded to the Share Point library. When user selects a file from the list & clicks on EDIT button we need to open the SharePoint file from the document library for editing. How do we open a SharePoint file for editing from a WPF client application (note: Share Point is not installed on the machine where the WPF application is used)? What's the best approach to accomplish this functionality?
Regards,
Vipul Mehta

I m trying to do insert,delete or update or any other data operation.
I have tried with following link
http://www.codeproject.com/KB/silverlight/crud-op-in-silverlight.aspx?display=Print[^]
but I am not getting the _mystore.SaveChanges()method when i try to do any operation (insert)
I m not getting where i m doing wrong....
Also then i have tried
_mystore.BeginSaveChanges(SaveChangesOptions.None, (asyncResult) => { _mystore.EndSaveChanges(asyncResult); },null);
in place of
_mystore.SaveChanges();
but the error occurs on this line that "An error occurred while processing this request." at
_mystore.EndSaveChanges(asyncResult); }
Can anybody suggest me some solution?
Thanks in advance,

There might be some changes in Astoria Data Service.
Please try to use the latest version of Astoria Data Service dll for Silverlight.
I will see if I can update all of my samples within this weekend.

Thanks for ur valuable response Michael.....

Hello,
After much searching on MSDN and other sources I have basically found that "some" Dependancy Properties do indeed support property value inheritance similar to WPF. However, as far as I can tell, there is no definitive list of which properties do, and which do not. I know Font properties, for example, do; yet HorizontalContentAlignment does not. I have also seen the other thread in this forum which points out that the DP Precedence list does not include value inheritance (http://msdn.microsoft.com/en-us/library/cc265148(VS.95).aspx#listing[^]).
Furthermore, it seems that it is not possible to even apply Inheritable metadata to any custom DP, so it seems the silverlight framework has custom hacked it in for specific properties. I need to know exactly which dependancy properties do indeed support property value inheritance. If I have missed an obvious article on this, or a thread, then I apologize but I have been pretty thorough in my search.
Thanks.

I've just looked at "Get Started Building Silverlight 2 Applications" on the Silverlight site. Step 2 of the 4 is Install Expression Blend. How viable is it to learn Silverlight dev without having Expression Blend. Say I only have Visual Web Developer Express SP1? (I've not actually downloaded SP1 yet, btw.)

- I'm doing it with VS 2008 only, myself...I think you have to install SP1 if you want to use Silverlight 2.0 final.
- I downloaded and installed the Blend trial, but it conflicted with my Office 2003 so I un-installed it.
- If you know Flash and are used to designing graphically, it's a little irritating not being able to click on the graphics you create in the XAML code. If you're more programmer oriented anyway, that wouldn't be a big deal.
- Some of the 'how-to' videos only show how to do it with Blend...if you were patient, you could probably get around it.
- Need Blend for keyframe-based animation if you want to do it like Flash.
So far, it's going well, so yeah, you can get by without Blend for most stuff, except keyframe-based animation

Thanks David, that's good to know. I'll have to install SP1 for Express. Can't afford a VS 2008 upgrade right now ("resting" contractor  ).
