My GPS application can detect not only a Bluetooth GPS receiver but also a GPS/GSM Micro Tracker(it was connected to my application via TCP). I have to send SMS command and it reply back the GPS data(NMEA data - $GPRMC). The problem is that the application can display GPS data($GPGGA) from the Bluetooth GPS receiver but it can't display the data from the gsm machine. Whenever I send sms, I receive back the GPRMC data and I can show it in my textbox but I can't display it on my VE map. The following problem occurs. Thanks in advance. Regards.

The followings are some of my codes.
private void ProcessNMEAData(string data)
{
string[] NMEALine = data.Split('$');
string[] NMEAType;
for (int i = 0; i < NMEALine.Length; i++)
{
NMEAType = NMEALine[i].Split(',');
switch (NMEAType[0])
{
case "GPGGA":
ProcessGPGGA(NMEAType);
break;
case "GPGLL":
break;
case "GPGSA":
break;
case "GPGSV":
break;
case "GPRMC":
ProcessGPRMC(NMEAType);
break;
case "GPVTG":
break;
}
}
}
private void ProcessGPRMC(string[] data)
{
double lat, lon;
double rawLatLong;
rawLatLong = double.Parse(data[3].Replace(":00", ""));
lat = ((int)(rawLatLong / 100)) + ((rawLatLong - (((int)(rawLatLong / 100)) * 100)) / 60);
if (data[4] == "S")
lat *= -1;
rawLatLong = double.Parse(data[5].Replace(":00", ""));
lon = ((int)(rawLatLong / 100)) + ((rawLatLong - (((int)(rawLatLong / 100)) * 100)) / 60);
if (data[6] == "W")
lon *= -1;
if (internetConnected && !loadingFile)
{
StringBuilder sb = new StringBuilder();
sb.AppendFormat("<div>Latitude: {0}<br/>Longitude: {1}<br/>Speed: {2}</div>", lat, lon, data[7]);
AddPushpin(lat, lon, sb.ToString());
}
else if (loadingFile)
{
object[] param = new object[] { lat, lon };
webBrowser1.Document.InvokeScript("AddPoint", param);

Hi,
in an application i used a trackbar to set input values to an output channel.
The arrow keys left right works fine, the arrow keys left decrement right increment the value.
But the arrow key up decrement and the arrow key down increment the value ??
with the key page up also decrements and the key down increments the value too ?
How could i fix this problem , so that arrow key up increments and arrow keys down decrements,
also the page up down ?

It's only a bug if you attribute "Up" to increasing the value and "Down" to decreasing it. If you turn the TrackBar vertical, the keys are correct. Visually, it's a bit backwards to reverse the keys.
You can create you're own TrackBar class by inheriting from TrackBar, then override the OnKeyDown method. Check for the appropriate keys and handle the Value of the trackbar yourself, skipping sending the keys to the base OnKeyDown method.

Hi, thanks for the answer,
i've created my own class, but if the code is running, nothing happens, because
if i press arrow up or down, this.value will correct set, but the control self set's
the value too (so he made the opposite and the control value is allways the same ) !!
Why ? i didnt call the base.OnKeyDown.
public class myTrackbar : TrackBar
{
protected override void OnKeyDown(KeyEventArgs e)
{
if(e.KeyCode == Keys.Up)
{
int delta = this.SmallChange;
this.Value += delta;
}
else if (e.KeyCode == Keys.Down)
{
int delta = this.SmallChange;
this.Value -= delta;
}
}
}

Rather than re-invent the wheel, try the printer manufacturer?

What is that you want to do ? Can you explain it clearly?

Walk up to it and rest your head against it??
Seriously, how is anyone supposed to answer that question?
What is it you're trying to do by "listening to a network printer"???

Hello,
I want to search a set of directories that are organized by "LastName FirstName". However, the number of spaces between each name might vary (most only have 1 space, but some have 2 or 3 b/c of a typo). The only search pattern I know of to accommodate this is "LastName*FirstName", but I'd rather use some regex like "LastName[ ]+FirstName", that only allows spaces between the names. Is this possible, or would I just have to get all directories and manually evaluate the regex on each one?
Thanks,
Dybs

You have to get the list of files and RegEx each one yourself to find the matches. The search options in the GetFiles methods, or whatever else you use, do not support RegEx expressions and there is no search option that will only match "any number of spaces".
