I wanted to use std::string but a function I use requires a const char[] as a parameter and string.c_str is no good. Unless there's a way to convert the string to a char when I'm done...
any ideas?
[edit] I guess string.c_str didn't work because I thought it was a variable, not a function. string.c_str() should work. Speaking of work, I think I work too much

hemm?
std::string s;
char an_old_array [16] = "";
s = "hy luke";
a_old_function (s.c_str());
strcpy (an_old_array, s.c_str());
do you have got any other questions ?
or what do you need exactly ?

perhaps you can use
YourConstChar=YourCstring.GetBuffer(0);

Shouldn't it be
<br />
delete [] pBody;<br />
instead of
<br />
delete pBody;<br />
?

of course..
sorry.. but i have to say that i hardly (say never) use c-arrays.. so.. that may be the reason why i didn't notice that..
yeah..
have a nice time..

Since I started to use STL in my application it depends on the MSVCP60 library. I thought that since STL is a set of template classes it would be static linked, but unfortunately it isn't.
Is there some way to avoid this dependency?

STL need not be linked in. Its a source code thing totally or that's what CG has got me to believe

Nope, STL just like anything else can be compiled into a DLL with the methods exported. You will find that the string class does this a lot.

Link with it statically (i.e. libc instead of msvcrt).
Project/Settings: Tab "C/C++". Select "Code Generation" from the drop-list. Select anything suitable that does not contain "DLL" in the drop-list for "Use run-time library:".

Hi!
I am using WINDOWPLACEMENT structure to get and set the size of window. Although the size of the window is correct, the left and top positions remain the same. So, the positon of my window never gets recorded. Does anybody know why?
Thanks,
NC

WINDOWPLACEMENT holds/sets information about the position info in certain states. It doesn't get/set the current positon of the Window.
Look at...
GetWindowRect()
SetWindowPos() or MoveWindow()

Does anyone knows where I could find a class that manages a CGI app? Like gets the environment variables, send stream to browser, etc.
I have some problems with the one I'm using right now so I'm looking for another one. I currently use TCGI you can find it at: http://hjs.geol.uib.no/CplusPlus/
Plus, if that class could be easily debugged (the one I use will always exit if I run the app in the console, so I can't debug!)
Thanks!

There's not really a lot of code needed. To get parameteres from post and get, read argv and call getenv(). To compose your HTML, just do couts or printfs.

I have very simple problem that When I disable the ComboBox which has type "DropDown". It becomes grayed. I want it to be in White Color.
I use "OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)" to change it but it dose not work properly .
I wrote following code
Following are Class Variables
CBrush bkBrush;
CBrush rBrush;
BOOL CMyDialogBox::OnInitDialog()
{
CDialog::OnInitDialog();
. . .
rBrush.CreateSolidBrush(RGB(255,255,255));
bkBrush.CreateSolidBrush(RGB(255,255,255));
. . .
}
HBRUSH CMyDialogBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
switch(pWnd->GetDlgCtrlID())
{
case IDC_COMBO:
pDC->SetBkMode(TRANSPARENT);
if(GetDlgItem(IDC_COMBO) != GetFocus())
hbr = rBrush;
else
hbr = bkBrush;
break;
default:
break;
}
// TODO: Return a different brush if the default is not desired
return hbr;
}
Remember that ComboBox has property of Drop Down.
Thanks in advance.

Use the following code,
if( pWnd->GetDlgCtrlID() == 1001 && pWnd->GetParent()->GetDlgCtrlID() == IDC_CMB )
return (HBRUSH)m_Brush ;
Here theIDC_CMB is the id of the combo box. In general the edit box of the
combo has the ID of 1001. This information is obtained by using Spy++.
But i do not think it will be changed in future.

Sorry!!!
It is Drop List.

I have writen a program with GUI in C++. It is used to get the many kinds of system message by using SetWindowsHookEx.
I have two functions.
The first is:
void createHook()
{
hMouseHook = SetWindowsHookEx( WH_MOUSE, (HOOKPROC) MouseHookProc, hInst, 0L );
}
The second is:
LRESULT CALLBACK MouseHookProc(int nCode, WPARAM wParam, LPARAM lParam )
{
LPMOUSEHOOKSTRUCT MouseHookParam;
if ( nCode >= 0 )
if ( wParam == WM_MOUSEMOVE )
{
if ( nCode == HC_NOREMOVE )
strcpy(szType, "NOT Removed from Queue");
else
strcpy(szType, "REMOVED from Queue");
MouseHookParam = (MOUSEHOOKSTRUCT *) lParam;
printf("Mouse at X = %d, Y = %d is %s\n\n", MouseHookParam->pt.x, MouseHookParam->pt.y, szType );
/// write to file to show result
f1=fopen("c:\\report.txt","a+");
fprintf(f1, "Mosue Location At ( %d, %d )\n", MouseHookParam->pt.x, MouseHookParam->pt.y);
fclose(f1);
///
}
return ( CallNextHookEx(hMouseHook, nCode, wParam, lParam) );
}
The problem is that if the mouse moves inside the GUI frame, the data can be saved in a text file and printed out on the screen, but the mouse moves outside the GUI frame, the mouse data can be only saved in a text file, but it cannot be printed on the console screen.
The printf seems not to run and by-pass this statement.
Why? plz help me, Hero!!! Thz a lot!!!

I just quickly browsed through your code and the if-statements at the beginning seem to be missing curly braces, at least the one after if (nCode >= 0).
You know, for kids!

Have you gotten any ideas how to remove the program (Uninstall programmatically, better not using the Registry)? The EXE is locked while the program is running, so it fails to remove itself
There's a trick with a BATCH-file, but you have to make a little pause before invoking DEL within it to let the app exit first; that's quite a problem too
Any ideas?

Make a loop in the bath!
e.g:
1:
>delete here<
goto 1
I think it was something like that...

Why don't you create a kit with InstallShield and then you have install and uninstall
