Dear All,
I just want to redesign one of our unmanaged VC++ apps.
I have drilled WPF for several weeks,but no solution has been found.
Because I can not play video stream from our unmanaged VC++ apps in UI.(I want to use CCW for communication between the managed WPF UI and unmanaged VC++ apps)
I am a beginner in programe, and thirsty for a solution.
Any hint and suggestion will be appreciated!

I don't know what the best solution for you is, but in my opinion
WPF isn't the best solution if you stay with C++.
First, WPF is managed. Second, you'll get no designer support in
Visual Studio or Expression for C++.

If WPF's features and programming model suit your needs, I would use
C# for the UI, keep your existing native C++ in DLLs if necessary, and
use C++/CLI to bridge between the managed and native code.
In fact, that's what I did/do Smile | :)

I appreciated your answer deeply.
Our native C++ app is such a big system based on document/view framework of MFC,including 10 dlls at least,that UI is only one of those.Replacing the UI with a new one with friendly outlook and usage is my task.
I will research C++/CLI at right.
Any solution else, other than WPF?

Hi all.
How can we simulate DragMove() method for the other elements in a WPF window ?
It means we could move an element with mouse points

I need to figure out how to customize cut&paste built in command on a context menu to do multiple functions. I need to highlight text from a text box then click on the context menu which shows up after right click, which needs to take me to a new form and automatically paste the text in another Text Box on the new form. I'm wondering if this is possible???
Any help would be appreciated..

Thank You!!

I have JSON string as a out put of some http://localhost:1586/Versentia.Web.UI/DataHandler.ashx
where requestAction = GetAll and requestType: ObjectInstances.
When I see the response using firebug, I can see the data returned by GetAll method,
But when I write follwing code, I don't get data;

var url = new Uri("http://localhost:1586/Versentia.Web.UI/DataHandler.ashx/");

WebRequest request = WebRequest.Create(url);
var response = (HttpWebResponse)request.GetResponse();
Stream dataStream = response.GetResponseStream();
var reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
var metaData =responseFromServer.Deserialize<dictionary><string,object>>();

I don't know how to access the GetAll method to retrieve the ObjectInstances object. I want to create WPF based on the retrived object. I am very new to programming and need to achieve this asap.
Please help.

Dyanmically creating tab items with similar input fields to the existing tab page

atl_5-Jan-09 11:35

5-Jan-09 11:35

In my WPF browser based application, I want to display a page with tab control. Each tab item in the tab control will display data for a single object in a collection in the application. The number of objects in the collection is known only at run time (so I don't know how many tabs the application will display at design time).

How can I create the content (edit boxes, labels, etc. for various data values of the object) on tab items that are dynamically created by the application based on the number of objects in the collection?

Any suggestions?

Thank you

Use a datatemplate to create your tabitems.

Use a ContentControl to display your collection, with this new datatemplate.

How to correctly bind to BLL objects in WPF

darthBug5-Jan-09 11:23

darthBug

5-Jan-09 11:23

Hello,

I used this MSDN guide (http://msdn.microsoft.com/en-us/library/aa581779.aspx[^]) to build BLL for my application. The DAL behind that BLL is a TypedDataSet.

To explain what i'm trying to achive i'll use two tables from the database:

Authors Table
-------------
AuthorID
Name
RankID

Authors Table
-------------
RankID
RankTitle

In the database i have a relation between these tables.

Following the mentioned MSDN guide i created BL objects for each table that return typed data tables, for example:
AuthorsBL.GetAuthors() returns AuthorsDataTable, AuthorRanksBL.GetAuthorRanks() reutrn AuthorRanksDataTable.

What i'm trying to figure out is how to create a window in WPF with a list box that lists all authors, a text box to edit the author's name and a combobox to edit/select the author's rank.

I can bind the listbox to the authors object and it shows the records, i can bind the combobox to the AuthorRanks table and it shows all records but i can't find a way to do so that when the selection in the listbox changes the combobox's selection will update too. I'm trying to do this the "right" way, as i see it, by using the XAML properties like DataContext, ItemSource, SelectedValue and SelectedValue path.
In the end i need to have a "Save" button to save all the changes so correct data binding is very important for me.

I'm not sure how to approach this, maybe the BLL should be built in a different way for WPF or i need some extra configuration in XAML.

Any help, explanation or a link to a guide will be most appriciated!

Thanks,

darthBug

Do we have a something like <i>z-index</i> (HTML) in XAML ?

Mohammad Dayyan5-Jan-09 10:03

5-Jan-09 10:03

Hi.
I'm going to create a layer above of any elements ! Confused | :confused:

In HTML we could do it with a something like this :

XML

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
<!--
#apDiv1 {
    position:absolute;
    left:259px;
    top:114px;
    width:329px;
    height:244px;
    z-index:1;
    background: #CCC;
    z-index: 10;
}
-->
</style>
</head>
<body>
<div id="apDiv1"></div>
</body>
</html>

Now I wanna know, we could do it in XAML ?
Is it possible ?

If you want to bring things to the front in WPF, then you really need to take a look at the 3D features of WPF. Welcome to the thing that really sets WPF apart from Win Forms.

I would probably use an Adorner or Popup (if it needed to be outside the window boundaries). If you override GetVisualChild and VisualChildrenCount you can create an adorner that displays any element easily. There are some articles on this site which use adorners and probably have everything you need.

I don't think so

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
