Yeah, it can still work. As far as I remember, it was a little difficult getting this to work with 2003 and 2002. Try searching code project or the web for binary resource or embedded resource.

I can get the file into a stream using reflection, however I can not find a function that will play a video from a stream, but rather from a path name. Is there something I need to download. Thank you very much for your help.

Mike - I love to program!

I really don't know, as of right now, the .NET framework doesn't provide any way to play video using native .NET, AFAIK. You need some 3rd party software like the ones I mentioned in the previous post. From there, it's a matter of finding the appropriate streaming methods.

In the end of the day you can just save the stream to a file in a temp folder, play the file and then delete it.

NumericUpDown Control and the tab key

Hi,

I have a problem. When I change the value in a NumericUpDown control and then leave the control using the tab key (without hitting enter), the change takes effect, but the ValueChanged event doesn't fire. Any way around this?

Thanks

IIRC there's a loose focus event, use that to do whatever you need done.

Timeout for diagnostics.process connection to remote host???

Hi all,

Using the following code under Visual Studio 2005 with .NET beta 2, I am looking for a way for the connection to timeout (in say 5 seconds) if it can't contact the host specified. Any ideas?
---
public string m_GetProcessList(string v_host, string v_processname)
{
string sendback = "";
Process currentProcess = Process.GetCurrentProcess();
Process[] remoteAll = Process.GetProcesses(v_host);
int v_processcount = 0;
string v_processIDs = "";
foreach (Process v_process in remoteAll)
{
if (v_process.ProcessName.ToLower() == v_processname.ToLower())
{
v_processcount = v_processcount + 1;
v_processIDs = v_processIDs + v_process.Id.ToString() + v_process.StartInfo.Arguments.ToString() + ",";
}
}
sendback = v_host + " - " + v_processname + " - " + v_processcount.ToString() + " - " + v_processIDs;
return sendback;
}
---
Thanks all.

How do I load a new form and access varables from it?

First Is This Variable Public if Yes You Can Do Somthing Like That in Form1

Form2 form2=new Form2();
form2.variableName=value;

If this variable is not public which will be better
You can Write public function in the form and make it set the value of the variable you can code somthing like thar in Form2 which have the variable you wwant to access

public voide SetValue(int i)
{
myVariable=i;
}

and in Form1 You can Write

Form2 form=new Form2();
form2.SetValue(1);

Sorry, I should have been clearer what I mean. I am trying to open a new form, (Form2), from my main form (form1)

On form2 are numerous controls which should change variables of form1.

Pass a reference to form1 in form2's constructor and store it inside form2:

in form 1:

Form2 form2 = new Form2(this);
form2.Show();

in form 2:

public Form2(Form1 refToForm)
{
this.form1 = refToForm;
}

private someMethod()
{
refToForm.SomeProperty = someValue;
}

Nunit for Databases

Hi All,

I doing some research for NUnit testing. I had a question related to its use for database testing. Should we avoid writing the tests for databases?
Please let me know.
Any comment will be appreciated.

Why? Don't you care if the database functionality works?

You should test all the database functions against a test version of the DB (with know data inserted), verifying that every function in you data access layer works as expected, and handles errors in a graceful way. Unless you do, changes to stored procedures, or schema changes, or fixes to other bugs, or enhancements could break your application in unanticipated ways. Test everything, including verifying that all schema is as expected, then you have a way to run regression tests that you can rely on.

Thanks for your response. I was told that it takes a lot of time and may not be useful, not even the client side code. It's good to test the business logic.

I am still tryinin to learn to write the tests...it's not easy to write them for the entire scope of the application.

Only test your coded methods such as business objects and data access objects and their interaction with handling the data that will be extracted and manipuated from a database.

Don't test the database such as how it handles data; otherwise you are an Oracle, Microsoft, DB3, or FoxPro database tester, which will be a complete waste of time.

Lastly leave the data isssues and normalization to a DBA. That is why they are paid the medium size bucks....

How to programmatically set the focus on a selected tree node?

Hello gurus,

I'd like to know how can I programmatically set the focus on tree node freshly created?
I can programmatically select it but the focus still remain to the top node. I'd like to programmatically set the focus on any new created tree node.

Best regards.

Fred.

you can set the focus on any node on the tree by using this syntax :

//TreeView object
System.Windows.Forms.TreeView treeview = new System.Windows.Forms.TreeView();

// Now you have to get the object to that node you want to focus

System.Windows.Forms.TreeNode node = //node rerefence of u want to focus
treeview.SelectedNode = node;
treeview.focus();

-
hope it will help you

Services start before any login is possible. Normal applications do not start until a user logs in. A good solution would be to have your service start automatically (ServiceInstaller.StartType set to ServiceStartMode.Automatic) and throw an exception from OnStart if the conditions are valid. Do not try to stop the service from within OnStart using the ServiceController. At this point the service controller database is still locked while startup code runs. If you try to stop it you will have a deadlock and any services scheduled to start after yours will not start - ever.
