• Software Development for Windows Vista InvokeWorkflow doesn't seem to run the invoked workflow's activities

  I have one main workflow that invokes a secondary workflow using the InvokeWorkflow activity. My secondary workflow is very simple, consisting of two code activities that dump a line of text into SQL Server so I can check to see if they're being run. However, once invoked from the primary workflow, these code activities don't seen to run. To debug I've attached to the StatusChanged event during the Invoking event and can watch as the secondary workflow is said to have "completed without error". So, I can tell that no exception is being thrown and there is no other path for the secondary workflow to take, yet the code activities aren't firing. Has anyone seen anything like this yet Probably that the host workflow is complete ...Show All

• Visual Studio Team System Can I use the XML/XSD schema as a source for data genaration?

  I have some XML/XSD schema which has table definition. Can I use this schema in place of the RDBMS table for generating the data And is it possible to have this data generated in the XML file Right now we either reverse engineering the schema from database or import it from Sql Script. And there is no direct way to import the schema from XML/XSD. A workaround is that you can write your code to create sql script so that it can be imported. For data generation, there is no direct way to generate data into xml file. You can generate data into the database first and then export them into xml file. Thanks, ...Show All

• .NET Development How to convert string to expression

  I am having an string "3<2", I would like to use it in a if statement as if(3<2). How to convert this string into an boolean expression. Can we convert a string like "a<b" into a boolean expression. You could use CodeDom - which is used to dynamically build up code (using code) to execute... have a look at the System.CodeDom namespace, in particular the CodeExpressionStatement class.

• Windows Forms Using ActiveX in C#

  Hi, I have created an ActiveX Control some years back, which i wanted to use in my current C# program. I'm able to instantiate it, but unable to use any of its functions, because it is throwing exception, i even checked the GetOCX property, it is also returning null. AxMyActivexCtrl obj = new AxMyActivexCtrl(); obj.Location = ......... obj.Size = ...... obj.Parent = this. try { obj.fun(); //one of the function exported by activex control, but exception is being thrown. } catch( AxHost.InvalidActivexStateException e) {} object temp = obj.GetOCX(); // even temp is null i studied MSDN, i found that this exception is thrown if ActiveX object is not instanstiated and not properly initalised. ...Show All

• Visual Studio Express Editions Submitting a Form over the Web

  How would I have the data that users input in a form be submitted to me say over an e-mail.  If you can not do this over an e-mail, could you please tell me how this would work. This is very important!  Thank you all. you can use the System.Net.Mail classes to send an email to a specified email address however you must generally give it the Credentials so it can authenticate your account. you would use a MailMessage object to construct the email (sender, to, subject, message etc....) then use the SmtpClient class to send the email, of course giving it the IP Address of the mail server/SMTP server.

• Visual Studio 2008 (Pre-release) XBAP and default browser

  Hi, I got the following problem since I uninstalled the February CTP and installed the May CTP instead: When I press Ctrl-F5 in Visual Studio for a XBAP application, Firefox is started instead of IE. Since Firefox doesn't understand XBAP, I cannot run or debug the application as easily as before. I know how to change the default browser for a HTML application, but I didn't find such a setting for XBAP applications. Any hint welcomed! Greetings, Laurent In your explorer, go to the .xbap file and rigth clic on it. Select Open With and choose IE. Check the checkbox "Always open ..." I think it will do the trick: I had the same problem and it works fine for me :) Bye ...Show All
