You can also try making a property as static for FORM1 and then add the reference of FORM1 in FORM2 then with the class name in which you have defined/declared the property as static; you can easily get it by Class Name.
|

|

Not a good idea - there are several much better ways to do this than using static. Consider the same problem when using non-Form related classes: If you use your static solution what happens when there are two instances? What happens when multiple threads are involved?
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Best Solution: Learn how to program in .NET and OOP. (This is quite a basic problem, I think you didn't understand the concept of instances, scope, access modifiers etc.)
2nd Solution: Follow the advices here (but don't follow the "make a static property" advice!)
Dirty Solution: Just declare your TextBoxes as "public" (you can set the "Modifier" in the VS-Designer).
I'd head for the "best solution" - learn your basics. This will really help you! ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Explain in more detail how Form 1 is related to Form 2. How are each instantiated? In what order are they displayed? Is it always the same or does this change?

Hi (im German so please forgive my bad english),
I wrote a c# .net 4.0 Program that gives me results from different calculations into different variables with different datatypes (myInt, myDouble, myString, myBool, myWhatevr)
Now i wanted to give al this results to my xml file that is used as a logfile.
This is my xml code:
using System;
using System.Xml;
namespace xml_exporter
{
public class xml_tool
{
public static void tel_toXML()
{
string dateTime = DateTime.Now.ToString("yyyyMMddhhmmss");
XmlTextWriter myXmlTextWriter = new XmlTextWriter("C:\\XML-Log_" + dateTime + ".xml", System.Text.Encoding.UTF8);
myXmlTextWriter.Formatting = Formatting.Indented;
myXmlTextWriter.WriteStartDocument(true);
myXmlTextWriter.WriteStartElement("Data");
myXmlTextWriter.WriteComment("Start");
myXmlTextWriter.WriteElementString("Farbe", "Blau");
myXmlTextWriter.WriteElementString("Struktur:", "Rau");
myXmlTextWriter.WriteComment("Farbnummer" "");
myXmlTextWriter.WriteElementString("Dichte", "");
myXmlTextWriter.WriteElementString("Name", "");
myXmlTextWriter.WriteElementString("Aktiv", "");
myXmlTextWriter.WriteComment("End");
myXmlTextWriter.WriteEndElement();
myXmlTextWriter.Flush();
myXmlTextWriter.Close();
}
}
}
Now i want to know how to give my variabel values to the xml construct!?
so that the xml-file should look "like" this:
Colornumber ValueOfmyInt variable Colornumber <br />
..<br />
Dichte 5.4 Dichte
etc.
However I searched in the c# openbook, msdn I didnt found the right answer to my problem. And there must be a Code or a Command to give the values of my variable to the XML thing.
I'm just always finding "how to read from xml" and stuff but thats not the same I think. Im still trying to build something up but its not working.
Ich flehe um Hilfe!
Does anyone have an idea how i can realise this ? Or a Link for exact this problem etc.? It would be a very big help for me.
greetz,
Sal

You want to write the value of some variables to XML? Did you scan the list of methods XmlTextWriter offers, in particular the ones that start with Write?
|
|
|
|
|
yes but maybe i understood it wrong. i thought write writes the file to a path not a variable to xml element.
ok worked for things like
Int32 = myInt = 3;
and then inserted the line : myInt.ToString()
so from now on the value is sended to the xml element.
thanks

Luc has already given you the answer, see here[^].
Just say 'NO' to evaluated arguments for diadic functions! Ash

Hi,
I'm trying to dial phone number and using SerialPort control for this, which is initialized with my USB modem.
SerialPort serialPort1 = new SerialPort("COM5", 115200, Parity.None, 8, StopBits.One);
serialPort1.Open();
serialPort1.Write("ATDmyphone\r");
serialPort1.Write("ATH\r");
serialPort1.Close();
everything works except 1 thing - there is no sound from the modem.
I tried to use ATM2 and ATL3 commands before I start to dial - but there was still no sound. But when I create dial-up network connection, and dial from its dialer - there is a sound.
What am I missing here?
thanks!

|

Are you sure it isn't just dialing pulse? That can be harder to hear than tone. You should use ATDT just to make sure.
|
|
|
|
|
I used ATDT as well - no sound 
|

Hi,
what does modem answer to each command?
Bye
|
|
|
|
|
this is the code:
serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceiver);
serialPort1.Open();
string answer;
serialPort1.Write("ATM2\r");
answer = serialPort1.ReadLine();
serialPort1.Write("ATL3\r");
answer = serialPort1.ReadLine();
serialPort1.Write("ATDT" + phone + "\r");
answer = serialPort1.ReadLine();
serialPort1.Write("ATH\r");
answer = serialPort1.ReadLine();
serialPort1.Close();
'answer's' value are commented.
thanks.

Hi,
please try ATM1\r instead of ATM2
bye

I tried, but there is still now voice

I don't know, however I would insert a big delay (3 seconds as a first experiment) between every pair of statements, so the system can settle before your program continues; as it is now, it is all done in a few milliseconds, maybe something isn't fast enough to keep up.
If that helps, you then can reduce the delays until it starts to fail again.
|
|
|
|
|
tried to put 3 seconds sleep between each command, but it still dials withut the sound.
|
|
|
|
|
try this below
serialPort1.Write("ATDmyphone;\r");
put ";" after your phone number

AFAIK, ';' tells the modem to return to return to command mode after the phone was dialed. How this may help?
I tried it, but still there is no sound
Thanks for your advice.

Then..,
that is very difficult to solve your problem by us, you have to debug the dialer software that which "AT" commands are sending to the modem,
Use a Serial Port Monitor to see the AT commands are sending by the dialer software..,
download the serial monitor from the following link

Did you ever resolve this? What modem type are you using?

Hi
I am looking for a solution to have self-written services supervised by a Network Management System using SNMP. From the second picture in the Article A simple guide to WMI providers it should be possible to use the WMI mechnism inside the services and expose the data through the SNMP service. But I din't find any useful ressource in the web. All I found were describing the SNMP Provider to access devices with a running SNMP agents.
Can you give me some useful ressources about exposing the data through the SNMP service? Maybe you've done it already and can give me an example? Or is it not possible?
Thanks for your help!
Greetings
Roland

Hi All,
Can you pls explain with example what is difference between Expression<Func<>> and Func<> in linq to sql query generation?
Thanks in advance,

Probably you can find here someone that could answer you, but I think that you have too much more chances if you move you post to the LINQ forum
