Hi Bravoone,
I have a hardware question do you know about DVD players?

the "Compare" function returns 0 (!!!) if the two strings are EQUAL, like strcmp(...)

For use of a dll on the C# you can use like this for example
[DllImport("user32.dll")]
public static extern int SendMessage(
IntPtr hWnd,
int Msg,
IntPtr wParam,
IntPtr lParam);
I dont know it was helpful for you?

Hello
I want to find a method to get the string width. When I surf internet, I find the function GetTextExtent() is available to get string width. I try it in my program use MFC based on SmartDevice(Wince), but the function is not supported in MFC.
Someone can kindly tell me which function is available to get the string width.
Thanks a lot.
Any suggestion is useful!! Thanks!!

It is supported on WinCE. Or do you mean something else ?

That function is part of the SDK (C code) and is supported. What exactly do you mean by string width? I am assuming the width in pixels. If so then say so, but you will probably get directed to the same function.
By the way, regardless of what the MS documentations says the string output functions are not limited to 8192 characters. The limit is dependant on the number of pixels required to draw the string (the width).

I am sorry for using the function in wrong way.
I want to paint string in AP and also to limit the range.
When I use the CString:: GetLength, I find it lsn't a good way to do it.
So I try to find a method to get the string width.
I use the GetTextExtent(string, string.getLength()) a moment ago and return CSzie.
I don't sure the CSize.cx value is pixels or not.
If it's true, maybe I can use the CSize.cx to limit the string number to paint in AP.
But are there more simple methods to do it??
Thanks a lot.
Any suggestion is useful!! Thanks!!

I am still not sure what you are asking, but ‘CSize.cx’ would be the width of the string in pixels. As far as I know there is no simpler method, although there are more complicated methods.
You can use the ‘GetTextExtent’ to determine the area you want to invalidate for drawing purposes, but I do not know what you mean by “limit the string number”.
‘GetLength’ returns the number of characters, provided it is not in Chinese or some other multi-byte language. That is if you are not using Unicode as the character type.
It has been a while but I have used ‘GetTextExtent’ and a few other methods while developing, for text editing and graphics string placement.

Because I will draw the string in the AP and the width is 251 in logical coordinates. If the string size are more than the width, I will add "..." to reply the words beyond the width. For example, if the string is "ABCDEFGHIJK" and I suppose that it is beyond the width, so I will show "ABCDEF..." in my AP.
I will try to use ‘GetTextExtent’ to get the string pixels and will to find transfer it in logical coordinates. I think it should be a good way to solve it.
Thanks a lot for your help.
Any suggestion is useful!! Thanks!!

What API are you using to paint the string? Maybe using one that clips the string will work...
Also, if supported, see GetTextExtentExPoint() which "retrieves the number of characters in a
specified string that will fit within a specified space..."

Dear all
i just created a simple project using vc++ 2005 express edition, but after i built this project, one issue occurred. output showed :"cl : Command line error D8016 : '/MT' and '/clr' command-line options are incompatible". so what happened?
second issue: when i add one item: windows form. pc showed me:you are adding a CLR component to a native project.your project will be converted to have common project language runtime support. so what happened? thanks a lot.
i am looking forward to your news.

If you want to use the .NET framework in your C++ app then you'll need to create a managed
assembly.
If you want a native Win32 application then you won't be able to use any CLR/.NET/managed code.

Try FileTimeToSystemTime function.

Thanks. i had the problem solved immediately after i posted the question here.

yes, I used the same function. Thanks anyways.

hi,
You can also use (in VC++, at least):
CTime time = CTime::GetCurrentTime ();
CString szEditTime = time.Format ( "%A, %d.%B.%Y, %H:%M:%S" );

What is purpose of padding of 2-2 bytes in debug build??
What are other important differences in Release and debug builds??
Thanks & Regards,
Sandip.

I am not sure what you mean. Usually the only reason for padding in debug is so that an overrun can be detected. I have seen that in the VC 1.52 and below compilers, but since VC6 and above have come out – I have not looked.
You will need to be more specific.

There is padding of 2 bytes before and later after each variable in debug build.
What is this paddign for??
|
|
|
|

I would assume that they are used for detecting over-runs and under-runs by the debugger, so that a crash does not occur during debugging. Of course I do not know this for a fact and may be some else does. All I do know is one of my environments padded arrays in debug mode and it caught me off guard when runtime analyses showed I was short one byte, because the runtime was not padded. That, of course, was my fault, but the fault was hidden in debug mode.
