Recurse through the directories and look for files in them. It's pretty simple to do.

How are we supposed to help you if you don't provide details of what the problem is?
Or are we supposed to guess?

How about more elaborate details as to what your problem is?

Hello everyone,
I'm making a program, but I'm (obviously) stuck with a problem.
I want to write a message to the current topscreen through a C# application.
For instance: when you open Microsoft Word and you type 'hello' it will double the word like this 'hheelllloo'.
The application allready knows when a key is pushed, now the only thing that will have to be done is write a message to the current top window (like word or notepad or whatever window is open and where you are typing in).
I guess that this is possible with something like PostMessage and GetTopWindow. But it won't work. Can anybody tell me what I'm doing wrong? Or can someone tell me what will work?
Thank you allready.
This is what I have:
[DllImport("user32.dll")]
public static extern int GetTopWindow(int hwnd);
[DllImport("user32.dll")]
public static extern int PostMessage(int hWnd, uint Msg, int wParam, uint lParam);
const int VK_KEY = 0x41;
const int WM_CHAR = 0x0102;
int WindowToFind = GetTopWindow(0);
Console.WriteLine(WindowToFind);
int result = PostMessage(WindowToFind, WM_CHAR, VK_KEY, 0);
Console.WriteLine(result);
The output for result is always 1.
The output for WindowToFind is different, sometimes it gives the same value at different windows. Sometimes a different value. One of the outcome of WindowToFind is 131138
edit:
Allright... finaly I found out the anwser to my problem (after hours of searching :P).
I just had to use the SendKeys class.
SendKeys.SendWait("<value>");
</value>

Hi,
Am trying to implement a progress bar in an application to copy files/folders. This progress bar is meant to sho the staus of copy.
Can anyone clarify:
1. What's the appropriate method for this to implement an actual status update using progress bar?
2. Whenever I put those two threads running (Main thread and progress bar) it seems the main thread is hanged until files are copied and the progress bar is updated once the copy process is over.
I came to know that, this can be sorted out in .NET2.0 using BackgroundWorker class but what can I do for this in .NET 1.1?
Regards,
Panicker.

Run the file copying in a separate thread. This will make your GUI responsive. When the file copy progresses, you need to update progress bar value. Check this[^] to learn how you can update your controls from a separate thread.

Hi all, I'm currently drawing a label on the top of my controls (combos, datetimepickers and so on) to simulate a readonly state. What I want to ask is if there is a way to know wich exactly is the 'client area' of the control (that is, without the right button and the borders) either with a ClientRectangle like method (since it seems that the provided one returns the whole size) or by checking if available somewhere the sizes of the single elements (width of the border, size of the button and so on)... Someone can help me?

hi,
I want to add contacts in active directory.I'm able to do so.
But the problem is that they r not reflected in Address book of Microsoft outlook.
When i investigated why this is so, i found it was because of some policy.
after discussing with support guys about what they do to manually add contacts, they suggested me to use MS exchange console instead to add the contact so that it will get reflected in few minutes into address book after adding.So how do i add a contact thru this exchange server console?
I tried to search on the net but i didn't find any help.May be any of u people could help me out.

I need to check status of serial port that using by some application
interface with some hardware.
Becuase I need to monitor satus of this comport by create my applition by using C#.
I want to check status of that serail port about "Now still tranfer data"
or "Stop to transfer data".
Because the application that opened this port can't tell me status of it
so I need to know status of this application by check serial port.
So colud please advise me about code on C# platform

Hi,
AFAIK you can't tell anything about a serial port unless you (try and) open it.
Which means, if some application has opened the port in order to use it, you can't open it
in a monitoring app since the port is "in use" or "allocated", and you can't get any
information whatsoever.
Of course, if the one app closes the serial port as soon as it is done receiving/transmitting,
then the monitoring app could try an open, and report success/failure. Mind you, if it tries
periodically, it may cause the main app to fail when that wants to use the port!
Also I am afraid the above is how serial ports work on Windows, no matter what language
and framework you intend to use.

Reposting is considered rude - please don't do it, it was only 17 hours ago you asked the same question which I have just responded to.
(Maybe you should add no-reposting to the guidelines Chris?)

It's a bit of an odd scenario since real serial ports don't tend to disappear, and it doesn't seem this possibility was taken into account when Microsoft wrote the SerialPort class: There's no event that indicates Com-port "disappearance" in it.
I guess your best option would be to start a separate thread that polls SerialPort.IsOpen every now and then: Most likely this will throw the error you got earlier when you disconnect the USB adapter, so you can catch that to see if the port's still there... Of course, you'll need to catch it at any other reference to SerialPort as well, that's just decent programming.
Alternatively, there might be a class somewhere in the .Net framework that monitors USB devices, don't have any experience with that. Could very well be a p/invoke kind of thing.
Standards are great! Everybody should have one!

Hi bankey,
"=" can't be overloaded in C#.
For your information other oerators like, . , ?:, ->, new, is, as, sizeof too can't be overloaded.

Panicker.
P.S. Mark as answer if you feel the reply is appropriate.

Hi,
you can implement implicit conversions though, so that may or may not solve your problem.
look for the implicit keyword.
