For me, too. And that's the reason I didn't answer it when he asked for it before. Sounds like a student that can't even do a google search.

What is the C# equivilant of Exit Sub in VB?
17 year old with too much free time.
...cooler than the other side of the pillow.

|

the equivalent is return
example:
private void DoJob(string jobName)
{
if(jobName == "")
{
return;
}
else
{
}
}

Hi!
I need to know how to capture the video signal from a microcamera connected to the serial port and then show the video stream in the PC (i.e, in a window).
Well, i know that the question could be so hard, i will really appreciate any help on how to interpret the video signal or how to show the video stream... any idea, link, book, or whatever.
Could it be done with DirectX?
Many thanks in advance!

Hi,
Capture a video stream with directX[^]
A video signal from a microcamera should be the same as any other video signal. You will have to see if you microcamera encodes the video (if it does, with wich codecs can you decrypt it)
You can definitly use the link above to display your video stream.
This will certainly not solve your problem, but I hope it helps

Hello:
Here are two programs
1) MyDotNetControl - A windows form control displaying some UI
2) MyVBClient - A VB COM client app hosting the above control.
You'll need to build the control first and register is using regasm for Interop. Then run the VB program from the same location as the component. The VB program describes and shows the errant behavior. This was complied using VS2003.
Different behavior is seen when build using VS2003 and VS2005
1) VS2003 - When the user control loses focus, the text box and button disappear (the label does not). On double clicking they reappear but not on repaint.
2) VS2005 - When the user control loses focus, the text box disappears (the label and buttons do not). On double clicking they reappear but not on repaint.
Has anyone seen such problem? If so, how did you work around it?
Since there was no way to attach files, I had to include the source code here. I have a ZIP file containing the source code. If you can send me your email I can sent it to you. This should save you time.
Thanks a lot!

Hi folks,
I'm working on a project thats an in house file replication system. FileSystemWatcher does a nice job of providing events for file/folder changes. But there is no way to know which process initiated a file change. Is there some class in Csharp or some Win32 api that does this? I have seen programs that do such a thing (but unfortunately not open source).
Thanks
-Francis
Do I need a signature?

No there isn't. The FileSystemWatcher class doesn't provide you with a ProcessID that you can use to track back to a Application name.
The other applications that you've seen do this, do not use the FileSystemWatcher. They are custom written and must install a virtual device driver that sits between the applications and the File System. This driver handles ALL the File I/O functions that applications use, log what's it's been told to do, then just forwards the calls to the actual File System functions that were called. The applications have no idea this is happening.
If you want an example of what I'm talking about, see SysInternals FileMon[^]. But there is no source code for it...

I am attempting to deserialize an object from XML. I have a stream setup to perform the deserialization from. My problem lies in the fact that the stream does not support the get_length function. This is because the stream does not have a length. It is similar to reading data from a TCP Connection, there is no inherent length of the data. I just want to read as much data from the stream as is needed to deserialize the object.
From everything I have read in the System.Xml.Serialization namespace everything appears to require this get_length function to be supported for deserialization. Does anybody have any Ideas.
thanks in advance,
Trevor

can you tell me what's wrong with this code here. there is only
one error, but I am not sure what it is. the problem is, that
the code that follows will not load a registry value into a textbox
I used a variable that was declared as "public static string" near the top
of Form1 (the first statement in the Form1 class near the top
of the page). this variable is used to tell part of the location
of registry key.("key1\\subkey1\\" + Form1.Variable + "")
I used Form1.Variable, becuase I am accessing the variable in another form
on the form's load event. However, when I use something like
("key1\\subkey1\\thisisnotavariablebutastring"), it actually works fine
without raising an exception. here is the code
<br />
public static string person1;<br />
<br />
RegistryKey key17 = Registry.CurrentUser.CreateSubKey("FamilyHome\\" + Form1.person1 + "");<br />
this.textBox1.Text = key17.GetValue("Monday").ToString();<br />
this.textBox2.Text = key17.GetVAlue("Tuesday").ToString();<br />
this.textBox7.Text = key17.GetValue("Sunday").ToString();<br />
<br />
<br />
if you need more info, or you want me to send you the full project with all<br />
the source code, let me know. I am so very grateful for your help.<br />
<br />
thanks,<br />
<br />

Hi,
I have a set of values(currency codes) stored in the database which I would like to retrieve and display in a Property grid as a non-editable drop down list at runtime.
I tried reading the properties into a ArrayList and then displaying the same in the Property Grid but that did not show up the drop down list.
Can anyone suggest how to go about doing that.
Thanks in advance!
Jaydeep

Check out the TypeDescriptor Class[^], there is an overloaded method called GetProperties which allows you to return a PropertyDescriptorCollection of properties. You can use the SelectedObject property of the PropertyGrid to assign your object. This should get you started.

Hi, I would like to know how to load 2 instances of "notepad.exe" (or any other exe) on each side of a split container inside my form, not to load when my application starts as an external program, but make it a part of my form so they both load inside my application when I start it.

what?? you can't do this unless you find a custom control and add it or you make your own.. its pretty easy to make it by yourself though..
