A service does not have a "desktop" to show the form on, which is why im guessing it errors. There is a setting ("Allow service to interact with desktop" ) which is part of a windows service properties which when ticked allows a service to interact with the desktop.
I have never tried showing a form or anything from a service but this may help get you on your way.
Good luck

I have looked for it, but I did not find that property , can you give me a hint from where can I tick it to allow the interaction with the desktop, please?

Go to your Service in Administrative tools, right click it and select Properties. On to the Logon tab there is a check box there.
Services are not "meant" to interact with the desktop they are meant to be back ground items.

oh! I was looking in the service properties in the C# environment,
can I make it interact with the desktop from the code itself?, so automatically being with no need to change the properties.

Im not sure to be honest, like I said before I have never tried to implement wgat you are asking before i was just aware of that feature on a service. Take a look through google is all i can suggest from here on.

Glad to hear it.

Might it be waiting for the opened form to close?

Stuart Celarier of CheckFree and I explore the new languages features in C# in a series of screencasts on Channel 9. Each is a whirlwind tours of the important language features since C# 1. Stuart describes the feature and why it is useful. But he doesn't get into best practices nor suggested usages. Just the facts about the feature.
Whirlwinds are bite-sized webcasts, each is shorter than 15 minutes. You can start anywhere in the series to learn about the parts you're most interested in.
Part one of the eight-part series has been posted Whirlwind 1: What's new in C# 2 - Generics[^]
In Part 1 about generics, Stuart describes:
- What generics are.
- How generics compare with collections.
- How the compiler treats generics.
- How generics increase performance and save memory.
This feature is part of C# 2 in .NET 2.0.
The remaining seven installments will be posted to Channel 9 over the next few weeks.

Version 2.0 of the .NET Framework has been available now for almost 3 years.
Is this a new definition of the phrase 'new language features' that I hadn't previously been made aware of?

Hi,
I have a project mixed with C++ and C# in VS 2003.
I tried to debug into the C++ code. but it never stop at any break point.
I use CoCreateInstance to create the C++ object (C# call a c++ library #1 -- managed C++, lib #1 call CoCreateInstance to create the final object). I want to step into the function call to that object. I have the source code for all the C# and C++ projects.
I set the "Enable unmanaged debugging" to true and also "allow unsafe code blocks" to true already. but it I can debug into library 1 only!!
does any one has some idea about this!!!
Thanks a lot in advance!

You have them all included and compiled in the Solution you are debugging from?

yes, all the projects are in the same solution. and I can compile it and run it. all the existing functions work fine. I want to add some new funcitons, so I need to debug into it!

Hi,
Problem:
I'm using C# 2005. The data type of the bitmap file saved to database is "long binary data". It should be "OLE Object".
Source Code:
Bitmap myBitmap = new Bitmap(@"c:\Picture1.bmp");<br />
OleDbConnection conn = new OleDbConnection("<<My Connection String>>");<br />
conn.Open();<br />
string sql = "UPDATE Table1 SET fldOLE = @fldOLE WHERE fldID = 5";<br />
OleDbCommand command = new OleDbCommand(sql, conn);<br />
command.Parameters.Add(new OleDbParameter("@fldOLE", myBitmap));<br />
int rowsAffected = command.ExecuteNonQuery();
Question:
How can I save Bitmap to database with data type "OLE Object"?
Thanks in advance

The data types of your DB are set when you create the table, not when you insert data into it. If you read here[^], you'll find how to get the info you need. If you look here[^], you'll find that this works.

You don't need an instance for static methods.
class User
{
public static void Foo() { ... };
}
call:
User.Foo();

I suggest doing a bit of reading on C#. Or some googling. If you did any reading at all on what a static method is, you'd have found your answer, and it's obvious you don't know, so you should move beyond solving your immediate problem, and understand what static means, and what it's used for, so that you move forward in learning the basics of C# and OOP.

Hello, i´m very novice with Visual C#. I want to make a player that can establish marks points of start and end on a video to save a subclip, for example I have a video of 10 minutes, and i want a subclip that go through minute 2 to minute 5, it would be a subclip of 3 minutes, and i want to save this subclip. I maked a player with AudioVideoPlayback with DirectX SDK. Is it possible to make a video player that can establish marks points using DirectShow library without the AudioVidePlayback or i have to use both, or i have to use another differents libraries or anything else?
Sorry about my english, I´m Spanish.
Thanks a lot.
Regards.

This doesn't really add up. I assume that you're not writing for a paid project and therefore a library like the tvideograbber from datastead is out of the question. That being the case, this task is probably beyond you, there's no built in support AFAIK, and you'd need to write a far amount of DirectX code. Learn C# first.

Crazy
Whats going wrong here?

I think there might be something wrong in way you make the form MDIChild! Can you post back how are you doing this? Other than that I cannot think of any other thing that would cause such problem

There is a method on the mdi container form to launch children.
public void ShowMdiChild(Form form)
{
Cursor = Cursors.WaitCursor;
form.MdiParent = this;
form.WindowState = FormWindowState.Normal;
form.Show();
Cursor = Cursors.Arrow;
}
|
|
|
|

Try this code:
<br />
<br />
Cursor = Cursors.WaitCursor;<br />
<br />
YourForm frm1 = new YourForm();<br />
frm1.MdiParent = this;<br />
frm1.Show();<br />
frm1.WindowState = FormWindowState.Maximized;<br />
<br />
Cursor = Cursors.Arrow;<br />
<br />
