I dont understand what you are trying to do. Do you want to access a control after you have cleared it? If so then you cant because clearing controls affectively deletes them
If you want something else then please try to explain again

Actually i have a usercontrol with 4buttons(1 DeleteButton), 1 textbox
In my form am creating usercontrol array(more than one usercontrols), After clicking on delete of a perticular user control am clearing that usercontrol from my panel. but
After Clearing the controls not deleting from my panel.just making invisible(i observed in debugging that, in array list it is showing cleared control also)
i want to chcek each and every usercontrol(from array) wether that control was cleared or not.
i hope am clear with my description.
i tried on creating a bool property in my usercontrol, on clicking deletebutton am making false that bool value., while checking am checking that bool value wether true or false. if false it was cleared control.
any other way to achieve this?

Hi,
The idea is to read specific media player registers. to get current played song informations:
In .net you can use the RegistryKey class to have acces to registers:
Note: Reg path from WMP: Software\Microsoft\MediaPlayer\CurrentMetadata
RegistryKey regData = Registry.CurrentUser.OpenSubKey("Software\Microsoft\MediaPlayer\CurrentMetadata", false);
if (regData != null) //you have to do this check, to prevent from a null reference exception
{
string currSongTitle = regData.GetValue("Title", "No Title") as string;
//...
// Check google to see other WMP Keys...
}
Hope this help

In my case can be useful RegistryKey class?
Sorry i'm beginner;

Hi everybody,
i've got an problem by starting an windows service on a remote server. This windows service should perform a database backup (from mysql to sql server) every day at a specified time (like a scheduler). I installed the service using installutil which is defined as local service with an automatically startup property. but every time i try to start this service manually the following error occurred:
Error 1053: The service did not respond to the start or control request in a timely fashion
I searched through the internet using msdn aso. but I only read about a bug in .NET Framework 1.0. I use .NET Framework 2 SP2 and also VS2008. Are there any problems if .NET Framework 3.5 is also installed?
Thx!!!

I am trying to develop a custom camera control, to use in my application. I access the camera with the SHCameraCapture api, however, this seems to give access to other functions within this dialog that I don't want the potential user to have access to, for example, changing the image resolution, saving the image to a location and sending via an SMS etc.
What I am after is a way to lock out all the other stuff that the camera api has, so that all the user can do is have access to 3 buttons, 'take picture', 'cancel' & 'ok'. How do I do this please, I have scoured the internet and all I can find is that there maybe a possibility to do it by having a C++ library using DirectShow within my C# application, which is most undesirable.

I take it the SHCamreaCapture API is not open source so you cant edit the source code yourself.
this [^]may help, there is some example code if you read down a bit

I am capturing an image from a Windows Mobile device with a camera on the back. I'm not sure how closely this is to capturing a webcam stream, not entirely sure about this.
SHCameraCapture is native code, which I haven't yet found a way to edit it's code. It is derived from the Aygshell.dll library.
Can the code on that thread be modified to make use of an in built camera on a mobile device, or is there anyway to 're-write' the SHCameraCapture code?

Hi,
I have windows app that uploads multiple files from a folder into the database. it takes a few seconds to upload all the files. what I need to do is to display a progress bar for the users to see that the application is still busy uploading the files to the database. I don't know how to do that in C# using Progress Bar control.
Please, can you help or advice on what to do.
Thanks.

Drop a progress bar on to the form. You can upate the value to indicate the percentage progress, or set the style to Marquee if it's not possible to quantify the progress.
If you wish to do the actual work on a background thread - I have a progressbar and backgroundworker combined here[^].
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

You can use BackGroundWorkerr in C#

Create a background worker in your application.
It has three events that you will want to handle.
.DoWork:
put you code that does the upload file here, at the end of each file report the progress as a percentage ( 100 / totalNumFiles * numFilesUploaded), this is done via BackgroundWorker1.ReportProgress()
.ProgressChanged:
update your progress bar value with the percentage passed as in the event args i.e. ProgressBar1.Value = e.ProgressPercentage
.WorkerComplete:
notify the user that the uploading has been complete or whatever you do after its finished.
Once you have coded these event handlers you can start the upload with BackgroundWorker1.RunWorkerAsync();
As this will start a new thread you will need to pass any data that your uploading code may need as parameters to the above function
i.e
string[] filepaths = {"file1", "file2"};
string destinationPath = "destination path";
BackgroundWorker1.RunWorkerAsync(new object[]{filepaths, destinationPath});
then at the start of your .DoWork event handler you can aquire these value with the following code:
object[] args = (object[])e.Argument;
string[] filepaths = (string[])args[0];
string destinationPath = (string)args[1];

i have a windows service and when any exceptions occur then its stopping... is there any way to restart that service automatically when it is stopped...
|
|
|
|
|
|
thans for that.. but is the code in the
public override onstop()
{
//progie code
}
will this function execute when the service is stopped due to abnormal execution such as exception....
|
|
|
|
|
It is unlikely that any event will fire when you get an exception. Your best bet would be to handle an errors and exceptions so your service does not crash. I dont really want to suggest putting the whole service in one try/catch block and doing some restarting code in that but its your choice what approach you take

ok... if you are free can u tell will the service crash when the exception eccurs in the service...and i am sending the data from systems on the network to the service. and when the number of clients get more i get the exception "The IAsyncResult object was not returned" at the client side and insted of client crashing my service crashes....can i get some help with this...
|
|
|
|
|
Im afraid i can not give you any detailed help on this subject but it appears that you have a problem handling your connections in your service. the service should ideally receive a request for a connection, check anything that may stop it using a new connection, and then report back to the client with a success/fail message in regards to the connection request.
EDIT:

Yes the service will crash just like any application would if an unhandled exception is thrown
