I have a function for updating data in the list control , i have called this function in the OnInitDialog() and this function is called only once while initializing , but i want that list control to be updated continuously in the run time,as that list control runs in the backround in the hidden mode.So kindly suggest where should i call that function so that function gets called in the run time with out clicking any button or any thing...

So i checking out for a function which i always called ,so that i can declare my function in it, through which my list control gets updated continously

Hi i used the same method iam not able to append the data in the excel sheet,can you kindly suggest how to do it ,below is my code

CCSVFile::CCSVFile(LPCTSTR lpszFilename, Mode mode)
: CStdioFile(lpszFilename, (mode == modeRead) ?
CFile::modeRead|CFile::shareDenyWrite|CFile::typeText
:
CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite)

{

Iam still facing the same issue,iam not able to append the data in the excel file,plz kindly help me to solve this,below is my code

CCSVFile::CCSVFile(LPCTSTR lpszFilename, Mode mode)
: CStdioFile(lpszFilename, (mode == modeRead) ?
CFile::modeRead|CFile::shareDenyWrite|CFile::typeText

CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite)

Its working fin ,one last thing every time i write in to the file its creating new file , i want to append the data in the same file.So how to do it.

Thanks for the solution ,but what about the second question ,do u have any idea about that.

2)And one more thing to ask you,i need a function in which i can keep my code so that it can be called continuously.I have written a code for list control and it gets updated only when the user clicks the refresh button,now i want to call that refresh button automatically with clicking any button for that i need a function which call continuously so that i can cal my function in it.

Hi Kuthuparakkal thanks for the immmediate reply

1)The above code is useful for me for the other application which iam building.
So i need to add the .cpp and .h files in my code and take the instance of the CXServiceManager and call the CreateService function.

But how do i exactly use this to install it in the registries and to start the application when the applications boots.

Can i have a sample code for CMultiLock::Lock

Now iam able to write in to the file but ,it is writing multiple times in the file ,For example if am having 10 items list control then if am saving those items in the list control,then 1st item is storing 10 times in first column and second one is storing 9 times in the second column it continues till other items ,i have atached my code to this plz check it

LPCTSTR lpszFilename = "XYZ.csv";
enum Mode { modeRead, modeWrite };
CCSVFile csvFile((LPCTSTR) lpszFilename );


int nlistCount = m_CtrlList.GetItemCount();

LPINT pItems = new int[nlistCount];

for(int index=0; index<=nlistCount; index++)
{
CString str1 = m_CtrlList.GetItemText(index,0);
CString DispName = str1 + "," + getDateTime;
CStringArray NameArry.Add(DispName);
csvFile.WriteData(NameArry);
}

yes i have included the .cpp and .h file

I have used this artical "Reading and Writing CSV Files in MFC[^]"
but iam linker error after using this.

error LNK2019: unresolved external symbol "class CCSVFile __cdecl csvFile

I have taken the instance of that class and called the WriteData() in my class.
This is how i have done

i want this write function to be done in the callback function.

i have taken the instance of the class with parameters and called the write function.
CCSVFile csvFile(LPCTSTR lpszFilename = "abcd", Mode mode = modeWrite);
csvFile(lpszFilename).WriteData(data);

i dont understand where have i done wrong plz help me
