Yes.

This is the unique ID for the control. there wont be no problem if a #define exists there.
the thing will get worse, if you add a control varibale for an existing control and if you delete that control from the resource file.
the #define may exists there in the resource.h file, so there wont be any compilation issue. But you will get an assertion in DoDataExchange function.
When we define control there will be an entry in the DoDataExchange something like this
DDX_Text(pDX, IDC_THIN_PEN_WIDTH, m_nThinWidth);
On deleting the control, it wont get removed.
Hope you clear.

Dear all,
how can get selected item in list box????
thx
|
|

You get the index of the element with the GetCurSel() function.
With the index you can get the text with GetText()

Iterate through the items in the list box using GetCount()
////// Check if the state of the item is set as selected
//////
for(int i=0;i<=m_pListBox.GetCount();i++)
m_pListBox.GetSel( i ) > 0 ? _T("true") : _T("false"));
//////Or use GetCurSel()
Somethings seem HARD to do, until we know how to do them.

m_ListBox.GetCurSel(); that return currently selected item
and use m_ListBox.GetText() for retrieves a string from ListBox

In my project code i hv these two instruction. please explain thease:-
1. m_CDBFile.write(reinterpret_cast(&m_Header.nNoOfRecords),sizeof(m_Header.nNoOfRecords));
2. nRetVal = MoveFileEx(lpBuffer,lpSystemDir,MOVEFILE_REPLACE_EXISTING);
THANK YOU

1) 1 st Parameter- _Str
Characters to put into the stream.
You are typecasting m_Header.nNoOfRecords
2 nd Parameter- _Count
Count of characters to put into the stream.
This is self explanatory
2)The nRetVal is used to test if MoveFileEx was successful.The value is non zero in this case
From MSDN
lpExistingFileName // First Parameter to MoveFileEx
[in] Pointer to a null-terminated string that names an existing file or directory on the local computer.
lpNewFileName // Second Parameter to MoveFileEx
[in] Pointer to a null-terminated string that specifies the new name of lpExistingFileName on the local computer.

Hi everyone,
I need to send data from a set of sensors via wi-fi to my PC. Once I have data in the PC, after making some operations with them, I have to send data again to the sensors, where there are a LCD to show a number.
Well, I don't know too much about wi-fi and I want someone to help me and start me in the wi-fi development. And how can I do this work.
Thank you in advance for your help and sorry of my bad english.

Hi again,
Well, I think I need an emitter and a receiver, didn't I? So, with those devices, can I work with IP's?
|
|
|
|

Um, sorry, I thought you had some devices in mind.
So yes... if you want to send data via Wifi, you're going to need an emitter and a receiver. You should browse manufacturers of such devices and read the docs on their devices.

Hi,
OK, thank you very much, Earl. One last question, Any suggestion, please?
Thanks so much again.
|

Sorry, no -- it's not really what I do. Besides, it's going to depend on what type of sensors you have, how much data, how far, etc. Your best bet is probably to find integrated devices, though I do think there are wifi boxes that will let you run code on them that talks over serial, etc. Expensive though.

hi tejaswini,
u should not do like that.
if u seperate the strings with semicolon, it will come as one string.
if u want multiple strings Ctrl + Enter

You said that you have the combo box with Type as drop down and adding string in the data box.
Did you go to the resource editor. Click on the arrow button of the combo box and then drag it down to some size to show the drop down list.
If not you will need to do so . Everything else works.
Somethings seem HARD to do, until we know how to do them.

In visua studio 6, you should specify the data seperated by "new lines" not with semicolon. you can use Ctrl+Enter for the same purpose.
In Visual Studio 2003, in the property page, we can't add data in new lines, hence we specifies it using ";"
Seems it's clear
