I always write my own code to run SQL scripts to restore a database. I don't know how you can integrate that into an MSI.

Hi all,
I am having a simple problem which is causing me to halt the project. anyways i want to declare a public string variable in a class. This variable is assigned a value from another class. The variable should be such that it can accept on a list of defined values.
Eg. declaring a variable such that it can only be assigned "test", "test2" or "test3". (on Vb.NET platform)
any help would be appreciated.

Expose a property and throw an exception if the value is not what you're expecting.

Use an enum, that is precisely what they are for.

You should use properties, events and that kind of stuff for that.

You might want to read this[^] little article.

Don't ever do that. Use delegates.

Thank you guys. Delegates..... How did i never tought on that....
You just rocked my world 
But i still have a doubt. I have read the article about the delegates and found it very useful, but it doesn't solves my problem.
I have a frmMain that calls a child. That childs calls a new child and in that second child i need to update the main. Like this (frmMain - calls - frmChild1 - calls - frmChild2 - updates - frmMain).
Does any one know how to resolve this?
Thanks in advance.

how to create si/psi editor for Digital Video broadcasting (DVB) using C#.net Language

One line at a time, I guess.
Any work on video in C# probably involved DirectX, I would think. But, perhaps what you want is more specialised and would require a third party library.

Hi,
I am trying to make a webpage with a link. When users click on this link, it launches a webbrowser on my server, do some stuff and return information.
Right now, I have successfully made my code for creating the webbrowser and processing data. But I cant seem to run it from an aspx webpage. It throws the exception :
ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment.
So now, I m simply trying to instanciate the webbrowser from the webpage and this still crashes as well.
I would really appreciate any help you could give me.
Here is the code that I ve got on my webpage for the link:
<br />
<form id="form1" runat="server"><br />
<div><br />
<asp:linkbutton id="launchBro" text="Launch the Bro" runat="server"><br />
OnClick="broMethod"></asp:linkbutton><br />
<br /><br />
<br /><br />
<br />
</div></form>
When clicked, the link launches this method in this class:
<br />
<br />
using System.Windows.Forms;<br />
using mshtml;<br />
<br />
<br />
public partial class _Default : System.Web.UI.Page <br />
{<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
<br />
}<br />
<br />
[STAThread]<br />
public void broMethod ( Object s, EventArgs e)<br />
{<br />
<br />
WebBrowser mybro = new WebBrowser();<br />
<br />
<br />
}<br />
<br />
}<br />
<br />
I also tryed to simply copy my class creating the webbrowser which is working into this project and instantiate it from this method, but it doesnt work either.
Thx,
Mathieu

Try adding the following attribute to the page: ASPCompat="true". From this[^] web-page.

Hi, Ed.
So far, I got rid of this exception by setting the following thread attribute : SetApartmentState(STA)
the [STAThread] does not work
<br />
<br />
public void CreateAccount ( Object s, EventArgs e)<br />
{<br />
Thread mystaticth = new Thread(new ThreadStart(Threadbrowsee));<br />
mystaticth.SetApartmentState(ApartmentState.STA);<br />
mystaticth.Start();<br />
<br />
Server.<br />
<br />
}<br />
<br />
<br />
public static void Threadbrowsee()<br />
{<br />
<br />
SimpleWebBrowser go = new SimpleWebBrowser();<br />
<br />
}<br />
So this does not throw any exception but it still does not do the work.  ) It just doesnt do anything.
I think your stuff is the stuff though. I m gonna investigate the Server.CreateObject and keep you inform.
Thx much for the help,
Matt

No you don't need the Server.CreateObject thing. What's happening is that I don't think you can apply the STAThread attribute anywhere except the Main routine of a C# program. Since ASP.NET websites don't and can't have a Main function then you can't apply it. However what that page described was the way to force a page into ASP compatibility mode which I understand is a Single Threaded Apartment model.
This might achieve what you want. Out of curiosity if you're simply wanting to parse the HTML returned throught the web-browser using a DOM (i.e. without having to parse the strings manually) you should check out the HtmlAgilityPack which provides a strongly-typed way of parsing non-xml compliant html. Works quite well apart from its lack of (at the time) support for LINQ.

Hi,
In my code, if I assign a dataset to the combobox datasource property,it is not getting assigned. The combobox datasource remains null. Because of this the combobox is not getting populated with the data.Can Some one tell me what could be the problem

A couple of things occur.
1. Is this an ASP.NET app? I'm asking, because even though you've posted in the WinForms section I don't want to make any assumptions. If so, you need to call DataBind().
2. Have you set the DisplayText/DisplayValue?
