Normally, when I want to replace string, I will write the code as
CString str="aaa-bbb";
str.Replace("-","");
The answer is
str = "aaabbb"
my problem is if
str = "aaa"bbb"
How to write the code to get the same answer?
bacause, if I write the code as
str.Replace(""","");
The complier don't allow me to do that.

Try this:
str = "aaa\"bbb";
and
str.Replace("\"","");

First, copy this function:
<br />
void ModifyStyle(HWND hwnd, DWORD dwRemove, DWORD dwAdd)<br />
{<br />
DWORD dwStyle = ::GetWindowLong(hwnd, GWL_STYLE);<br />
DWORD dwNewStyle = (dwStyle & ~dwRemove) | dwAdd;<br />
<br />
::SetWindowLong(hwnd, GWL_STYLE, dwNewStyle);<br />
}<br />
Call it like this: ModifyStyle(window_handle, WS_SYSMENU|WS_MINIMIZEBOX|WS_MAXIMIZEBOX, 0);
This will remove all the buttons in the caption bar.
However, I don't know how to make just the close button appear without making it a tool window.

#define MACRO_FUN(b) { if(b) return; printf("2");}
inline void Inline_Fun(bool b)
{
if(b)
return;
printf("2");
}
void Calling_Fun()
{
//Inline_Fun(true);
MACRO_FUN(true);
printf("1");
}
int main(int argc, char* argv[])
{
printf("\n\t");
Calling_Fun();
printf("0");
printf("\n\t");
return 0;
}
When I call 'Inline_Fun(true);' o/p is 10 ..... while When I call 'MACRO_FUN(true);' o/p is 0. Why like this? ( I am using VC6)
I want to return from 'Calling_Fun()', when control reached to 'return' statement of 'Inline_Fun(bool b)' < same as in 'MACRO_FUN(b) >
Thanks & Best Regards,

what is o/p? You have a serious flaw in your macro. When you define a macro, the preprocessor replaces the code where ever you used the macro. So when using MACRO_FUN, at compile time the code would look like
void Calling_Fun()<br />
{<br />
if(true) <br />
return; <br />
printf("2");<br />
printf("1");<br />
}
But you inline function, will not do the same. The return statement will exit the function and return to the Calling_fun() function then print your statements.

a macro is a text replacer.
given
void Calling_Fun()
{
MACRO_FUN(true);
printf("1");
}
the preproccessor gives to the compiler the following:
void Calling_Fun()
{
{ if(true) return; printf("2");}
printf("1");
}
A inline function is -instead- an ordinary function that is compiled in the including unit. No preprocessing is involved, so the return in your inline_Fun returns from the function.
There is no way to do what you ask in the way you expect because the language semantics is not as you intend.
a workaround can be the use of exceptions, but if you are in trouble in distinguishing a macro semantics from a function semantics, that's not the way to go.

Hi, I use the following code to get the name of the current desktop, but the buffer is not filled.
char s[MAX_PATH];
DWORD l;
...
GetUserObjectInformation(GetThreadDesktop((DWORD) GetCurrentThreadId), UOI_NAME, s,l);
...
Why this happens?
Is there any other methods to get the name of the current desktop?

Your last parameter to GetUserObjectInformation() is wrong. It needs to be the length of the buffer in the third parameter ("s" in your case). In your example, the value should be MAX_PATH.

Hi,
In a current project we have massive problems of locating memory leaks, so I was ordered to write a class using the PDH performance log functions that allows to take performance shots (used handles, allocated memory etc.) at specific points. On this way we want to locate which actions of the program are the big memory eaters and where we have to concentrate on, or if the whole problem is a memory leak at all or maybe simply a fragmentation problem.
As I'm new to PDH I wanted to ask, which counters I should use to get the allocated memory of a specific process. I know there is the Page File Bytes counter which shows how much of the Page file is used by the system, but is that all I need? Is there maybe a special counter giving the total amount of memory allocated by a process or do I (or my evaluating Excel-sheet) have to sum up several counters?
Is PDH a component of every Windows XP installation no matter how minimal the installation will be, or do I have to deliver the PDH.dll with my other project dll files just to be sure? Or if I enter the pdh.lib in the link file, it should be linked statically and my class doesn't need the pdh.dll any more, correct?
Bye

Oh, BTW I'm using Visual Studio 6.0 programming for Windows XP Professional plattforms, just in case that this influences your answer

Hi all,
I have to work on an application that implements whiteboard feature and allows two people sitting in remote locations to modify and work on a single file.(Say a word document or a text file). Changes made by one person are reflected on to the other's machine.
Any ideas/suggestions?(Link to articles/samples that achieve something of this sort)
Somethings seem HARD to do, until we know how to do them.

Use a memory mapped file giving it a unique name when opening it. CreateFileMapping(). Just search the articles here for "shared memory" you will find several examples.

Hi,
I need to detect whether is mouse left button down...
I need somethink as GetMouseButtonDown(...)
Thanks

Well, a few days have passed since he last asked. I suppose it's possible that the whole way Windows handles messages might've changed since then 
|
|
|
|

You don't understand me!!! I know WM_LBUTTONDOWN, WM_MOUSELEAVE and all mouse messages!!!
But I need to get mouse flags wherever in code... Ouf of CWnd object, simply wherever
|
|
|
|
|
What I was trying to say was that there's nothing there to tell you what the mouse is *currently* doing, just messages that happen when the status changes.
All you need to do is have a boolean member in your class - in your LBUTTONDOWN handler, set it to true, in MOUSELEAVE set it to false
|
|
|
|
|
But I don't do this!!! Because if MOUSELEAVE then left mouse button don't to be UP...
Simply, I want to attest whether mouse left button is UP or Down when mouse is out of window (CWnd object)... You understand me???

You might need to use the SetCapture function.
