VS 2010 could not find database at design time

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :WPF
 

Hi all, I'm having this problem....
Scenario: C# 2010, WPF, SQL Compact 3.5 SP2.

I'm working at a wpf window which loads records from a SQL Compact DB and shows data in textboxes. At runtime everything works perfectly but since this morning (working on it last 2 days) i'm not able to edit the window at DesignTime.

As soon as I open the window with the wpf editor I got the error (translating from Italian):

"Impossible to find the database. Check the database path. [Data Source = C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\thedbfile.sdf]"

Now, in settings and app.config I have the connection string which is something like

Data Source=|DataDirectory|\thedbfile.sdf

I don't understand why and where NOW (only since this afternoon) at Design Time VS look that path for the database, while at RunTime it's ok.

Again, I'm using Datasets, and I can preview data, ecc., as said everything is ok except the edit of the window which crash with this error....

thanks

"Could not find default endpoint element that references contract " @ Expression Blend @ Design Time

  

so, in Expression Blend, and only there, during design time i get an error:

"System.InvalidOperationException was unhandled by user code

Could not find default endpoint element that references contract 'GBAUploadService.IGBAUploadService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."

this doesn't happen in Visual Studio 2010, and of course the service itself works flawlessly.

any ideas?

 

the code triggering the exception is part of a ObjectDataProvider, which consumes a web service in code-behind:

 

  public class FileGroupsDataProvider
  {    
    public BaseUploadJob[] GetFileGroups()
    {
      if (Assembly.GetEntryAssembly() != null)
      {
        using (GBAUploadServiceClient gbaUploadServiceClient = new GBAUploadServiceClient())
        {
          BaseUploadJob[] baseUploadJobs = gbaUploadServiceClient.GetFileGroups();
          return baseUploadJobs;
        }
      }
      return null;
    }
  }


huge number of data from database ... so how to minimize load time

  


Hi ...

I have used the above method to configure my crystal report ...

Its working fine , But i have huge number of data in database ....

So , it take long time to load the report ...

So , i have decided to show only the last 50 records inserted into the database , not all the 500 records to be loaded every time.

Plz help me with this issue  ...

 

Also , Plz explain me abt index legend in crystal report.


Can this code be setup to run against the whole database instead of just 1 record at a time?

  

We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.

thanks.

  
            strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"        
  
            getStaticRecordSet(strSqual)   
            'get the new transaction_id out for just inserted alarm   
            strSqual = "select max(transaction_id) as transaction_id from trans"  
            set rst = getStaticRecordSet(strSqual)

Thanks for any feedback.


Custom Control Design-Time SiteMap Provider Error

  

Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

<siteMap>
      <providers>
        <clear/>
        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
             siteMapFile="web.sitemap" 
             securityTrimmingEnabled="true"/>
      </providers>
    </s

ASP.NET Designer - How Do I generate this Design-Time Markup?

  

Hello,
I want to generate this:
    <x:MyControl id="a" runat="server">
       <Scripts>
            <x:MyScript .. />
       </Scripts>

How do I persist custom complex types in design-time

  


Let's say that I've got one custom webcontrol called MyControl.



[ParseChildren(true)]
public partial class MyControl: WebControl {
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerProperty)]
public IComplex Complex { get; set; }
}


The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex


public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}
}


Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.


<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-

Crystal Report Asking for Database Authentication each time when I view Page.

  

Whenever I open my Crystal Report page, I am taken to the Database Authentication page where I am asked for

User name
Data Name
Password

each time.

Is there a way to avoid this and I save these authentication in my page once.

I am using VS2005, C#.

Any Help will be appriciated.

Thanks

Data Binding: Give Your Everyday Custom Collections a Design-Time Makeover

  

In this article, Paul Ballard shows how you can provide data binding support for your custom collections to enable sorting, searching, and editing in as simple a manner as possible. In addition, he shows how to make all of these features available in the Windows and Web Forms Designers, just like an ADO.NET DataSet.

Visual Studio .NET: Building Windows Forms Controls and Components with Rich Design-Time Features, P

  

This is the second of two articles discussing the extremely rich design-time features of the .NET Framework. Part 1 discussed the basics, showing you where to start and how to extend your control implementation through attributes and interfaces, as well as their effects on the property browser, code serialization, and other controls. Part 2 continues the journey by concentrating on design-time functionality that you can implement beyond your components and controls, including TypeConverters, UITypeEditors, and Designers. It would be impossible to cover everything you can do in two short articles, which is a testament to just how all-encompassing and flexible the design-time capability of the .NET Framework is.

Visual Studio .NET: Building Windows Forms Controls and Components with Rich Design-Time Features

  

Visual Studio .NET provides support for designing rich features into your controls and components, allowing you to set properties, set form placement, inherit from base classes, and much more. So how does Visual Studio .NET do all this? What does the Windows Forms designer do? What's the difference between a control and a component? How does Visual Studio integrate your controls so that they can access features of the .NET Framework?In this article, the authors answer these common questions by building a clock control and taking the reader along for the ride. In building the control, hosts and containers are illustrated, the property browser is explained, debugging is discussed, and a general overview of the design-time infrastructure is presented.

UserControl, CustomControl Design Time Support errors IOC, Dependency Injection, MVP

  
  Hi, is there a way to completely disable design time support for CustomControl, and UserControl ? I have about 30 UserControls and 10 CustomControls in my WinForms app, which contains some Dependency Injections and IOC stuff in constructors and Load handlers. I have lots of large UserControls containing smaller UserControls (CompositeView). All my UI code is pretty dynamic and the only thing i need to do at design time is to drag&drop containers in other containers (UserControls). And now i have a hard time doing this, because i have to wrap all constructors and Load Handlers in CurrentProccess!="devenv"... and when I'm Implementing some new View interface (which consist lots of properties) in UserControl all those properties by default throw NotImplementedException and i don't always need to implement them immediately but still i need to be able to run this code for testing. Besides, then i have to clean up designer generated class because it adds unnecessary null value property initializations, and then it way add some other ____ code, and so on.... Imagine UserControl with 10-15 nested UserControls, and then i try to open it in Form Designer and get ObjectReference NULL exception (for IOC) or some NotSupported NotImplemented exceptions (for properties) without adequate CallStack available! There is a CallStack but there is no trace in it to my Code (

For a control which events are raised at design-time, run-time or both?

  
Hi. I have been getting several different errors on the my windows forms designer. I'm trying to implement an application with some complexity on the screen navigating since it includes several main views as also sub-views in which the sub-views are represented by user controls. I believe that some of my errors are related to the fact that I miss important information related the events that are raised while working in the windows forms designer. Is there any link that includes information about the events of a control that are raised at design-time, run-time or both? For example, if I override the OnLoad() method of a User Control, that method will be executed both at design-time and run-time. Knowing about this information has helped me resolving an issue related to duplication of columns on a customized DataGridView. Not 100% sure if it's possible to obtain what I'm asking for or if this information exists. If this information is not available what could I do in order to understand in more detail the kind of events that are raised in the design-time vs run-time? Can I debug an application in design-time using Visual C# 2008 Express Edition? I found this link that helps identifying the run-time and the design mode: http://dotnetfacts.blogspot.com/2009/01/identifying-run-time-and-design-mode.html This link has been helpful but I still feel that I need more information.
