why not you try char array ? so that u can take the particular item .. m_tem[1];
thanx

.. maybe, so that your m_tem is really only one char wide.
BTW, there must be better ways (meaning safer ways) to do this :

wchar_t *m_T=(LPWSTR)_bstr_t(m_str);
~RaGE();

TextOut displays a string, not a character. Passing &m_tem, TextOut still treats it as a string and, as such, is exactly the same as m_T.
By the way, as has been alluded, CString doesn't like to be messed with internally like you might be trying. Use a char array instead, or you're going to blow something up later.

I have a dialog that use to send data using IP address. The dialog include a IP address box to key in the IP address which is the destination IP address. It also have a send button that when I click on it, it will send the data to the destination that I key in the IP address box. Beside that, the dialog also include some button that have their name such as open door, close door, on aircon etc. When I click on those button, it will automatic send the button name to the destination.
This dialog just add all those button but did not do the program inside the dialog. So the dialog cannot work exactly what I mention above. I don't know how to do the program for the send button and the IP address box which is when I key in the destination IP address and the message that I want to send and last click on the send button, it will send the message. thank you very much if somebody can help.

Hi,
I have a problem with using a path. I have to obtain the program files' path programatically, therefore I use this function.
CString PFPath;
SHGetSpecialFolderPath(NULL,PFPath.GetBuffer(_MAX_PATH),
CSIDL_PROGRAM_FILES, FALSE);
MessageBox(PFPath);
and the message box says:
C:\Program Files
I need to add something at the end of this string and then i try to use it in another function which needs the paths in double back slashes like:
"C:\\Program Files"
Then I try to do a conversion in PFPath in order to double the backslashes to change from
"C:\Program Files" to "C:\Program Files"
int i=0;
i = PFPath.Find("\\",i);
while( i>-1 )
{
CString found;
found.Format("Backslash found at index: %d",i);
MessageBox(found);
PFPath.Insert(i,(CString)"\\");
MessageBox(PFPath);
i += 2;
i = PFPath.Find("\\",i);
}
if(i==-1)
MessageBox("No more backslashes");
MessageBox(PFPath);
The message box output of this path is:
Backslash found at index: 2
\
No more backslashes
\
As seen, the insert function turned the whole string into a single backslash instead of inserting one.
CString WholePath = PFPath + (CString)"\\some_folder\\myfile.exe";
SHELLEXECUTEINFO shellInfo;
...
shellInfo.lpFile = WholePath;
::ShellExecuteEx(&shellInfo);
The conversion cannot be done properly, and shellInfo.lpFile needs double slashes. Therefore ShellExecuteEx cannot receive the path.
I have also tried the '\' conversion issue with CString::Replace; CString::left, CString::Right and concetanation with operator +. Now I'm almost convinced that it is not possible to do it with the CString class. 
Is there any other way to convert the '\' to '\\'?
Regards and thanks in advance,

Hi,
if you want to get the path of your application, just access your
theApp.m_pszHelpFilePath member. Its extension is "hlp". Just cahnge it to "exe".

It's not my application actually.. There might be several applications whose "theApp" I don't have.

Sorry,
I missed the point. If your want to wrap your path name, try something like that:
CString getWrapped(const CString& Text, char Esc)
{
CString buffer;
int size = Text.GetLength();
buffer += '"';
for(int i = 0; i < size; i++)
{
char c = Text[i];
if ((c == '"') || (c == Esc))
{
buffer += Esc;
}
buffer += c;
}
buffer += '"';
return buffer;
}
CString test = getWrapped(path, '\\');
Is this your question?

The example I posted recently was previously developed for the std::string class.
If you are just using CString objects wrapping is even easier:
CString test;
test += "\"";
test += path;
test += "\"";
test.Replace("\\", "\\\\");

I do not want to put quotation marks to both ends of the text.
I want to convert a string (i.e. CString) like C:\Program Files to C:\\Program Files - which is doubling the back slashes...
Regards
|
|
|
|

Ok, that's a one-liner 
If you have
CString test("C:\\Program Files");
just call
test.Replace("\\", "\\\\");

When the string has a backslash it acts differently. I know that to add a quotation mark, you need a backslash in front of it. CString::Insert and CString::operator + act different when there is a backslash in the CString object. I'm sorry to say that I could not get a result with the code you sent either.
Regards

I'm a bit confused...
I can't find a difference between CString::Insert and CString::operator+
I sent you an email with the example I have coded...

I see that it works with your code, but not with the code I have, which is similar to yours (see my initial message). I don't understand.
Thanks and regards

Hi,
this time I implemented your posted code back-to-back and got the same error.
The problem is related to the CString::GetBuffer() method.
CString::GetBufferSetLength() should fix the problem.
But I would prefer:
char buffer[_MAX_PATH];
SHGetSpecialFolderPath(NULL, buffer, CSIDL_PROGRAM_FILES, FALSE);
CString PFPath(buffer);

You don't actually need any conversion. The double back slash is needed only when you are writing a string literal in your code. That's because the back slash is a escape character (used in combinations like \t, \r and \n, to represent a tab, carrier return, and line feed characters), when what you want is an actual back slash character, you need to type it twice. However, the double back slash pair represents one (single) back slash character in memory.

I have a problem on updating an sql server database.
The connection string that I give is as follows:
"Description=description name;DRIVER=SQL Server;SERVER=server_name;APP=Microsoft\x00ae Visual Studio .NET;WSID=wsid;DATABASE=dbtest;Network=DBMSLPCN;Trusted_Connection=Yes"
I open multiple tables of the database as snapshot.
The first problem that I have is that I want to search for a value of a field in one of the tables, so I use the MoveFirst and MoveNext functions. The MoveNext function doesn't work!
The second is that when I run the AddNew function I get the error "Recordset is read-only"!
Does anyone know how can I get the privilege to move in and change the database?
Thanks in Advance

Hello all,
How can I programatically change the default push button style from one button to another button in a dialog?
|
|
|
|
|
If you want to copy a button's style to another one you can get it by using GetStyle() or GetStyleEx() that returns a DWORD and set the other button's style by using ModifyStyle or ModifyStyleEx.

I mean:
<br />
DWORD dw = m_button1.GetStyle();<br />
m_button2.ModifyStyle(0, dw);<br />
... she said you are the perfect stranger she said baby let's keep it like this... Tunnel of Love, Dire Straits.

Thank you.
But the problem is still alive.
I use the following code for show buttons which are hidden initially. If the fDefault is set TRUE that button should have default push button style. Always button[0] gets this style. I'm sure that I will set this style only to one button at a time.
void CDlg::Enable(int iBtn,LPCSTR sTxt,BOOLEAN fDefault)
{
m_button[iBtn].SetWindowText(sText);
m_button[iBtn].ShowWindow(SW_SHOWNORMAL);
if(fDefault)
m_button[iButton].ModifyStyle(0,BS_DEFPUSHBUTTON);
}
Can you help in this problem, please?

Use SetButtonStyle instead of ModifyStyle.

You can do it, at design time, in the resource editor via the button properties->tab. But I don't remember how to do it at run time.
