Assuming you want three places after the decimal, use:
strTemp.Format(TEXT("%.3f"), fVal);If, however, you are wanting to remove all trailing zeros regardless of how many, see the TrimRight() method.

The above will fail on fVal = 1.051000 (provided I understood his requirements).

Actually it fails also on his input (610.15100000).

How so? strTemp has a value of 1.

It worked fine for me. strTemp has a value of 610.

But it needs to be 610.151. Thanks though!

So use .3 instead of .0 then.

I think he wants to remove trailing zeroes in a general way, i.e. that his input was just an example.

Yeah, I read it wrong. I thought he wanted to remove everything after the decimal. Sorry for the confusion.

You may use strTmp.TrimRight(_T("0")); to the purpose.

strTmp.TrimRight(_T("0")); works as long as I have numbers after the decimal, but if I don't, it leaves me with whole numbers that end with a decimal, i.e:
610.00000
would become: 610.
However, strTmp.TrimRight(_T(".0")); seems to work! Thank you much!

Please tell me how to use the functions present in a DLL file in a new WIN32 console application.
I want to use a function from an existing DLL file, in a new program.
Thanks.

On Visual Studio, usually you have to:
(1) include the library header file
(2) add the library .lib file to you project.
(3) make the IDE know about the folder path of your library .lib file.

There is a dialog and it has more than one controls.I want to get all these controls to set or change some their properties at runtime. To do this , i use that code.
<br />
CWnd* pChildWnd = wnd->GetWindow(GW_CHILD);<br />
<br />
while ( pChildWnd )<br />
{<br />
pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);<br />
} <br />
But i can't get controls and this while loop enters infinite loop. Please help me to get all controls. Thanks.

Can't you use EnumChildWindows()?

Hi Experts,
I have written a shell context menu COM dll. It is working fine on all files and folders. But this is not coming on briefcase. How can I achieve that.
|
|
|
|
|
I would suspect that the briefcase is not a real directory, but a namespace extension (like the recycle bin). In which case, you might be out of luck.
For this sort of thing, I use regmon from sysinternals. Navigate to the "directory", start regmon going, and see what COM reads explorer does when you right click on a briefcase item. It may not even look at the keys you have your extension registered under, which would be a hint to give up, or look if any of the keys it *does* look at give you any ideas.
Iain.

Hi!
I'm trying to make all DropDown-Menus transparent, using a WH_CBT hook.
Unfortunately it does not work ...
Here is the Hookprocedure:
<br />
LRESULT CALLBACK TransWindowProc(int nCode, WPARAM wParam, LPARAM lParam)<br />
{<br />
if (nCode < 0)<br />
return CallNextHookEx(g_hTransHook, nCode, wParam, lParam);<br />
<br />
<br />
<br />
if (nCode == HCBT_CREATEWND)<br />
{<br />
<br />
HWND handle = (HWND)wParam;<br />
<br />
LPWSTR szClass = new WCHAR[128];<br />
GetClassName(handle, szClass, 127);<br />
<br />
<br />
<br />
if (lstrcmpi(szClass, TEXT("#32768")) == 0)<br />
{<br />
<br />
SetWindowLong(handle, GWL_EXSTYLE, GetWindowLong(handle, GWL_EXSTYLE) | WS_EX_LAYERED);<br />
SetLayeredWindowAttributes(handle, 0, 200, LWA_ALPHA);<br />
<br />
}<br />
}<br />
return CallNextHookEx(g_hTransHook, nCode, wParam, lParam);<br />
}<br />
The hook itself is in a dll and is installed correctly. The if-statement is entered, but no transparency is set.
Can anybody please help  ?

Hi,
I was trying to find some way to change a const value using pointers (just for the hell of it).
I guessed const is a compile time restriction and not a runtime one.
I came across this.
The code compiles and runs without any error.
It displays 12 20, even though the code suggests p and y must be having a value of 20.
I am surely missing something here. Please help.
<br />
void main()<br />
{ <br />
int *px;<br />
const int p = 12;<br />
px = (int *)&p;<br />
*px = 20;<br />
int y = p;<br />
cout << y << " " << *px; <br />
}
Then I tried this.
I made p a global variable. This one compiles without any error or warnings(highest level).
However throws access violation on *px = 20; at runtime! This is against my (wrong?) understanding of const.
Please can someone throw some light on this issue?
<br />
const int p = 12;<br />
void main()<br />
{ <br />
int *px; <br />
px = (int *)&p;<br />
*px = 20;<br />
int y = p;<br />
cout << y << " " << *px; <br />
}<br />
I used MSVS 6.0 compiler.

I have a (very loose) theory, but words escape me at the moment. Making a variable const only tells the compiler to not allow reassignment of p. The data (of p) is not in a special location, it can still be altered by px (to 20). When you printed the value of p in the first example, even though it had been changed indirectly by px, the compiler knew that it was a const and thus returned its original, read-only value.
That's as bad of a description as I can give you at this point.

Hi David,
Thanks for the reply, I really appreciate it.
Definitely compiler is playing some role here. I will check the assembly code that's generated.
I am wondering how the runtime error is generated in the second part of my problem.
Thanks
Paul

In the second case the compiler has almost certainly placed p into a readonly segment as it's a global constant. I know MSVC 6 does this with strings so it's not really a great surprise it does it with an int.
In the first case I would speculate that you're falling foul of optimization. Try turning off all optimization in you compiler/project settings and see if it still occurs. I would certainly class that as a compiler bug though, not the only one in VC6 by a long chalk
