How can I convert LPCTSTR to CString ?

SherTeks23-May-08 2:33

23-May-08 2:33

LPCTSTR CSample1Dlg::GetTheComputerName()
{
TCHAR infoBuf[MAX_COMPUTERNAME_LENGTH + 1];
DWORD bufCharCount = MAX_COMPUTERNAME_LENGTH;

GetComputerName( infoBuf, &bufCharCount );

return (infoBuf); //Here infoBuf = "XYZComputer" (which is
the computer name)
}

.
.

LPCTSTR lpstr = GetTheComputerName(); //Here lpstr = "XYZComputer"

CString csComputerName(_T("");

csComputerName = CString(lpstr, 15); //Here csComputerName = Garbage

How can I have the computer name in csComputerName (which is a
CString)?

What the '15' you pass in the constructor of the CString ? Just remove it and it will be fine.

How do you check that csComputerName is garbage ?

Thanks for the reply.

I've used one of the prototypes of CString constructors that is :

CString( LPCTSTR lpch, int nLength );

The 15 specified is just an hard-coded value of nLength.

I tried removing nLength as you suggested, but didn't work.

How do you check that csComputerName is garbage ?

Ans : By way of debugging

I found that the pointer to 'infoBuf' was getting lost as soon as the 'GetTheComputerName()'
returned.

There are 2 ways to resolve this :

1) Declare TCHAR infoBuf[MAX_COMPUTERNAME_LENGTH + 1]; in a .h file as a data member.
OR
2) Make 'infoBuf' as static if it is locally declared within 'GetTheComputerName()'

Thanks for your support.

Because in the CSample1Dlg::GetTheComputerName() you are returning the stack variable - infoBuf. The stack variables will get deleted when the function returns.

I can suggest another method. Pass a CString by reference to the function. Then inside the function, get the computer name and assign to CString param. For instance see the code snippet.

void CSample1Dlg::GetTheComputerName( CString& csComputerName )
{
    TCHAR infoBuf[MAX_COMPUTERNAME_LENGTH + 1];
    DWORD bufCharCount = MAX_COMPUTERNAME_LENGTH;
    
    GetComputerName( infoBuf, &bufCharCount );
    
    // Assign the computer name to csComputerName
    csComputerName = infoBuf;
}

...

// Call it like this
CString csComputerName;
GetTheComputerName( csComputerName );

Edit box cursor control ?

Thanks for the suggestion.

Re: Edit box cursor control ? [modified]

23-May-08 1:24

Can someone please point me to the source of info on how to control Edit box cursor?
Function SetDlgItemText(....) sets the text fine but moves the cursor to the beginning of the text. I need the cursor at the end of the set string.
Also would like to be able to erase/delete all current text using ESC or Delete keys only. The "default" Enter key is "routed" to default button. How to I intercept this message?
Thanks for your help.

Thank you, works almost as advertised!
Looks like a typo "(WPARAM)m_wndEdit.m_hWnd,", but I already have a focus so I did not need to send this message anyway.
I would have a tough time figuring this out myself, you are very helpful. Thanks again.

yes, i just coded this for MFC, and I assume you were not using MFC, i mapped to win32 soon, Corrected now.

Rajkumar,
No problem, I did modify your code and it does what I wanted to do.
There is a minor bug in it - after the cursor is moved I can no longer backspace in the Edit box. I'll try to figure out how to do that.
Thanks for your input.
Cheers Vaclav

How to conversion from upper case string to lower case in MFC.

24-May-08 4:18

The problem is not with the text / cursor insertion. I have another problem with my program.
When I insert the text and cursor (result of SQL search)and than attempt to do backspace my application continues to do SQL lookups on the inserted text in the list box and gets "out of control" causing it to reinsert the last text.
I'll need to work on that. I'll let you know after I fix it.

CString has the MakeUpper() and MakeLower() functions, but you need to understand that upper case and lower case exists only in English (and may be in those languages that uses English script). It is not a very good idea to make this call on a language like Hindi. I believe you understand it.

I am talking about those languages which has no UPPER or lower cases. It just would not mean anything do a conversion in that case. I also mentioned "Hindi", in my previous post, as an example.
