Have you started tabindices from '0'?
|
|
|
|

yeah started from "0" and asigned all other controls as in the correct order of number, but even when i try to get CurrentFocusTabId = CurrentFocusTabId.ToString(); i couldn't get the current control's tab index id

Set the DateTimePicker.Format property to Custom and DateTimePicker.CustomFormat property to space.

But i want to do in runtime.....

You can do this at runtime. What is the problem?

In addition to what d@nish said, you must initialize the value to DateTime.MinValue, and in the methods which use this value, make sure it's not DateTime.MinValue - this ensures the user has selected a date.
Also, in your dateTimePicker1_ValueChanged handler, use dateTimePicker1.Format = DateTimePickerFormat.Long; or whatever format you want - otherwise the user will see an empty box, no matter what he selects!
Cheers,
Vikram.

You should have researched that before choosing your platform.

Hi,
i'm beginner in MODBUS, so please help me.
i have a temperature regulator with MODBUS communication.
For example:
If i want to read holding register e.g.: 0042 „Value of temperature“ from mentioned device, in my application for MODBUS-RTU communication which i was writte in
Microsoft Visual Studio 2005- VC#,
i made request -byte array:
{0x01, 0x03, 0x00, 0x29, 0x00, 0x01, 0x83, 0x01}
1- slave adress (configured in device)- 0x01
2.- function code(Read Holding Registers)- 0x03
3.- start adress Hi- 0x00
4.- start adress Lo- 0x29
5.- no. of registers Hi- 0x00
6.- no of registers Lo- 0x01
7.- error code- 0x83
8.- exception code- 0x01
and sent that array to device. Label Rx blinks ,on the front panel of device, so device received my request, but i don't get any response, Tx doesn't blink!!!
For example:
If holding register 0042 „Value of temperature“=555, response message from device should be:
{slave adress=0x01, function code= 0x03, byte count= 0x02, register value Hi= 0x02,
register value Lo= 0x2B,... } !!!????
But i get nothing!!!!
All other parameters like port name, baud rate, parity, data bits, stop bits,ReadTimeout, WriteTimeout and RS485/RS232 converter are O.K.
Plese, could You help me with some advice to get response from device and tell me what i do wrong.
Is my request -byte array O.K.??? (especialy last two bytes 0x83, 0x01- CRC)
Thank You very much.
Best regards!

Without seeing any code or knowing what transmission media that you're using, it's difficult to say with any certainty where the problem is.
Try using this[^] to check your CRC bytes. Here[^] has some links to tools that may help you.

Hello everyone,
I am using the following code to retrieve the string content of XML, my question is why there is many trailing zeros in variable content? How to solve it?
static void Main(string[] args)
{
MemoryStream MemoryStream1 = new MemoryStream();
StreamWriter StreamWriter1 = new StreamWriter(MemoryStream1);
XmlTextWriter XMLWriter1 = new XmlTextWriter(StreamWriter1);
XMLWriter1.WriteStartDocument();
XMLWriter1.WriteStartElement("Entity");
XMLWriter1.WriteAttributeString("node", "Hello Node");
XMLWriter1.WriteEndElement();
XMLWriter1.WriteEndDocument();
XMLWriter1.Flush();
string content = Encoding.UTF8.GetString(MemoryStream1.GetBuffer());
return;
}
thanks in advance,
George

Hi! All
I m working on a project who has images, icons defined in Resources Properties. All these loads at run time. but when i remove some images from Resources then it prompts error messages. I want to handle it if the image exist then it appears if it does not exist then does not.
Let me tell how to Handle this
these are accessed as
this.BackGroundImage = MyProject.Properties.Resources.Logo;
it is ok
when i remove "logo" from Resources.
then a compile time error: logo is identified.
* So far i handle this. as i make an empty image with same name i removed.
but that is the not a solution.
Any suggestion regarding this. will be anticipated.
Thanks in advance.

Instead of linking the file at compile time, you can embed it in the .resx file. There will be a Persistence property for the image when you open the Resources.resx file in IDE.
Also, If you want to remove the image, you can remove it from resources also, why you want to keep it if its not used?
