I'm not sure what you mean but i think what you need is WCHAR or wchar_t (or maybe simply short). So WCHAR** or wchar_t** (or short**), LPCWSTR.

You may use TCHAR ** or LPTSTR *.
BTW

Is wrong, in fact you use a LPTSTR as generic text mapping for char * (and wchar *).

Problem: A User is using "copy and Paste" from a MS Word and MS Works database to enter data into my nprogram. And it fails to accept the special chars contained in each database. How do I strip those special chars from those databases before the User can "copy and Paste" from them?
Heres how I extract the data from my database file into a vector:
void CSystemDB::ConvertStringFromFileSys(CString str)
{
// Take the string data from the file and convert it back to
m_vSys.m_vSysData.clear();
CString e = "";
CString s = "";
CString c = "";
CString d = "";
CString x = "";
m_cSysData.CleanUp();
int sizeOfString = str.GetLength() + 1;
LPTSTR lpsz = new TCHAR[sizeOfString]; //[sizeOfString];
_tcscpy_s(lpsz, sizeOfString, str);
int nStop = 0;
int i = 0;
int ntmp = 0;
int ntmp2 = 0;
d = '*';
e = "";
c = ',';
int ch = 0;
int nQuit = 1;
int nLastchr = sizeOfString - 1;
int index = 1;

switch(index)

I thought about loading another(or several) CStrings with "OD' OR 'OA' Ex: CString CR = 'OD'; but I don't know if that would work in the example code above.
Any help would be appreciated. This is MFC VS2008 code.

As you can see by the code I presented, No. That code segment is where I read from the file what the User typed(or pasted in). It's here that I need to strip the Special chars, etc from the database.

And what are those special characters? What does the input look like? What should the output be?

Hi All,
I have a doubt in costum tree control.I created a CDragDropTreeCtrl for drag and drop purpose.
The code is:
RECT rect = {25,29,190,250};
m_treeCtrl1.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|TVS_TRACKSELECT|TVS_SHOWSELALWAYS ,
rect,this, 1001);
rect.left = rect.right + 25;
rect.right = rect.left + 170;
m_treeCtrl1.SetBkColor(RGB(192,192,192));
m_treeCtrl2.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|TVS_HASLINES|TVS_LINESATROOT
|TVS_HASBUTTONS|TVS_TRACKSELECT|TVS_SHOWSELALWAYS ,
rect,this, 1002);
m_treeCtrl2.SetBkColor(RGB(192,192,192));
PopulateTree(m_treeCtrl1);
rect.left = rect.right + 25;
rect.right = rect.left + 170;
m_treeCtrl3.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|TVS_HASLINES|TVS_LINESATROOT
|TVS_HASBUTTONS|TVS_TRACKSELECT|TVS_SHOWSELALWAYS ,
rect,this, 1003);
m_treeCtrl3.SetBkColor(RGB(192,192,192));
now i need the double click event for this tree control.I dont know how to write it.Bcoz it doesnt have the ID(because custom tree control).
Pls help me............... 
Thanks & Regards,
Anitha

You can use the WM_NOTIFY with the NM_RCLICK message. Such as:
ON_NOTIFY(NM_CLICK, IDC_TREE1, OnClickTree1)
ON_NOTIFY(NM_RCLICK,IDC_TREE1, OnRightClickTree1)

Hai !!
How to change the caption of AfxMessageBox ()
i could give the message but the caption remains the name of the project !!
Can i change it ??
Thankyou !

AfxMessageBox[^] is simply a wrapper for the MessageBox Function[^]. I would suggest that you use that instead if you want to modify the caption.

Add an entry with the ID AFX_IDS_APP_TITLE to your application's string table, and set the value to the title you want.

Hello,
My application is an mfc application which is connected to server throughtout.
Now if the internet connection failure is there then then i display a meesgebox that please check your internet connection.
And the applications keeps on requesting from the server.
How ever if the internet connection does not get better early the the appplicaton keep on requesting from thes server i.e. it gets busy in itself as the messagebox next gets fired after 213 calls.
How should i manage it so that it does get busy itself and the user does not have to forcefuuly end it.
Thanks In Advance.

Hi, I am programming a simple matrix class with the following = and + operator definitions:
Matrix<T> Matrix<T>::operator=(Matrix<T> rhs)
{
if (v!=NULL)
delete [] (v);
iRows=rhs.iRows;
iCols=rhs.iCols;
v=new T[iRows*iCols];
for (int i=0;i<(iRows*iCols);i++)
*(v+i)=*(rhs.v+i);
return *this;
}
template <class T>
Matrix<T> Matrix<T>::operator+(Matrix<T> rhs)
{
Matrix<T> sum(iRows,iCols);
if (iRows!=rhs.iRows || iCols!=rhs.iCols)
throw Exception("Matrices dimensions do not match", __FILE__, __LINE__);
else
for (int i=0;i<(iRows*iCols);i++)
*(sum.v+i)=*(v+i)+*(rhs.v+i);
return sum;
}
where
private:
int iRows;
int iCols;
T* v;
Now, I try the code: C=A+B,
The point is that before the return sum assings the sum value , the matrix variate sum is destroyed by the Matrix class destructor as it is a local scope variate, and I get a debug assertion error. On the other hand, if I comment the destructor code block, there code works fine.
Thanks in advance.

Why the assignment operator doesn't return a reference, as it should do?
Why didn't you implement also the copy constructor?

You are right. I changed my code so many times, that didn't notice about the assignment operator did not return a reference. Anyway, that is not the problem, I still get my sum variate destroyed before returning anything. what does the copy constructor have to do with the + operator?

Hi All,
Im having the .bmp file in tree control.If i will click that file, it will open in paint using MFC(I dont want in VC++).
Pls help me...........
Thanks & Regards,
Anitha

Hello Anitha,
You can use the ShellExecute Function[^] to launch the either the default BMP extension handler or "%windir%\system32\mspaint.exe" with lpParameters set to the file path for only MSPAINT.

Hello!
I'm not sure i understood correctly what you are trying to achieve there, but if you have the path to the BMP file you want to open when it is clicked you could try using ShellExecute, for example something like ShellExecute(NULL, "edit", <path_to_your_BMP>, NULL, NULL, SW_SHOW) or maybe ShellExecute(NULL, "open", <path_to_paint>, <path_to_BMP>, NULL, SW_SHOW).

Do you want to load and show bmp file yourself?
|
|
|
|
|
yes.I need to load the .bmp file in tree control.If i click that file it will show in pain.

This has already been answered (assuming you are not wanting to know how to respond to a mouse click).

I think David answered to your question and for show your bmp file you can use of LoadImage or CImage class.
