Yeah I'm not too sure about that one. I always use PNG as I have found that it has the highest quality and smallest file size. But I have noticed a few problems when using PNG's with the PictureBox, I'm not sure what causes these problems, but all I know is that when I select "Auto-size" I don't have any problems with the PictureBox.

It turns out the problem was with SizeMode. Using an ImageList seems to automatically use Zoom. Taking the image from Resources doesn't, and all I could see was the top left (transparent) corner of my image!!

I noticed that for async calls, when unhandled exception is occured, JIT debugger is not showing typical dialog box with stack trace/continue/quit buttons. Instead the standard error report dialog box with Send Report/Don't Send buttons. Is there any way to make unhandled exceptions in async calls like begininvoke/begin* to show JIT debugging dialog box?
Thx

You need to catch ThreadException IIRC.

well, since the question is how to _make_ c# catch itself all unhandled exceptions from within async operations, then I don't really want to catch ThreadException, unless I missed some point.

Hi,
I am using DateTimePicker Control to display Date in to Custom Format like 2009/07/13 (YYYY:MM:DD)
But the date is not changing according to user selection. Is there any other controls in .net 2003?
Thanks,
Subbu

Hi,
You have probably made simple mistake in the format string.
The following will output e.g. 2009/07/13. Note that you have to enable custom formatting via the Format property.
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "yyyy/MM/dd";

Hi,
I am working on a project involving communication using GPRS. We have a GPRS enabled modem that sends data to server at regular intervals. All I have to do is develop a service that reads the data sent from GPRS enabled modem and save into database.
I request any one who has experience in these type of projects to guide me in three things.
1.How to establish connection between Modem and Server
2.How to read data received by the server
3.How to close the connection
Thanks in advance

Your question is way too broad for a specific answer; in general terms the answer is this:
1) figure out how the device is sending data (read the documentation)
2) code your service accordingly
I'm doing the same thing right now - here's what I encountered. Our devices are configurable; we chose UDP sockets as our preferred communication method so we programmed the devices with the required commands and then used this[^] in a service on the server to read incoming data. The other option was to use TCP/IP in which case we would've used this[^] and this[^] on the server to receive data from the devices. All of those classes have methods for opening and closing connections (if applicable) and reading data. We ruled out comms via SMS on a cost basis.
Hope that helps.
Jim

No, there isn't. It's always painted using the system colors.

No it's not, since any change you make there affects ALL applications and windows, not just your apps. Changing system-wide settings just to make your app look pretty will ultimately get your app uninstalled.

Don't use
foreach (string filename in filenames)
{
PlayMedia(filename);
}
Instead write an event. When one song is completed, fire that event within WndProc
if (lEventCode == EC_COMPLETE)
{
m_objMediaControl.Stop();
m_objMediaPosition.CurrentPosition = 0;
m_CurrentStatus = MediaStatus.Stopped;
UpdateStatusBar();
UpdateToolBar();
// Fire that event
}
Then clean up and start the next song. Hope it will help

Hi!
thanks, I am new to c# and also media files. could you please provide me a snippet as to how this can be achieved. I also need to delete it from file list once played. thanks in advance.

Sorry friend,
Today I am in a bit hurry. Currently I am in my office. You can consult any preliminary C# book on how to create an event and fire it. It is a very simple one. Sorry again, don't mind
