Look for the CxImage article here on CodeProject. It does decent scaling.

How can I show text in arabic and hebrow languages, in my window, whitout Unicode. in ANSI mode and notifying Windows to use associated character set for each language?
also, what is the benefit of SetThreadLocale and similar functions? which one of them can solve my problem?
|

I am not prettey sure about the arabic language whether it is single byte or MBCS. To show your arabic and hebrow languages in your window, you have to use proper font and char set.
Install or findout a suitable font which support the arabic or hebrow languages and use the arabic or hebrow charset when creating a font. This will resolve your display problem.. But more over operating system also considerable...
SetThreadLocale () gives you support at API level.. Suppose your system deals with date, time, currency etc, you MUST set your locale so that windows API will do proper handling. Otherwise they do default implementation...

Hi
When the user select some files and copies them in using rightclick->Copy, or Ctrl+C how could an application get those files?
To make myself more clear, I want to retreive the files that user have selected and copied.
(I have tried the GetClipboardData() API but I couldn't get these information out of it.)
|

Hi,
I hope your coding in managed c++, if so you can have a look at the method System.Windows.Forms.Clipboard.GetDataObject. You can use the data object it returns to get the files.

when i add #define UNICODE to my stdafx.h . it says:
>>cannot open file "mfc42ud.lib
here is my stdafx.h :
#define _UNICODE
#define UNICODE
#if !defined(AFX_STDAFX_H__C1E8B1B1_B28C_4E3B_B6B5_49C7878BCAC5__INCLUDED_)
#define AFX_STDAFX_H__C1E8B1B1_B28C_4E3B_B6B5_49C7878BCAC5__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

#include // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT
what should i do??

BECAUSE !!!
you don't include the lib in your project  suss:
TOXCCT >>> GEII power
[toxcct][VisualCalc]

When you install Visual C++ 6, there's an option to include Unicode support (ie the Unicode libraries etc). This isn't selected by default, so if you didn't pick it, the Unicode versions of the MFC libraries won't be on your system, hence the link error. The solution would be to reinstall VC++, making sure you select the Unicode option. (and don't forget to re-apply whatever Visual Studio service packs you installed before, or else the Unicode and non-Unicode libraries will be out of step).

Hi,
Do not reinstall your VC++, instead Go to Control panel and Add remove software. There you can select Visual Stuio then select the option equal to modify. IT will display installed components. Select VC++, click details, there you have to select MFC, then unicode library.
Otherwise Simple solution is , Click Select all which will enable all the features..

Unfortunately, your approach doesn't work with VC6, which predates the Windows Installer options you are describing.

Can you give me some general information on CFixedALlocNosync::Alloc() function or the whole class.
Its really urgent. don't know wat to do anymore.
I have an MDI application, Doc/View Style.. and then i have 2 additional Frame/Views attached on a ControlBar and those Views are views for the Document... So I have 1 Doc-3 Views..
When originall when the application is Opened by default, opening a New Document, the program works fine..
Now, when i launch the application with no New Document created, and then I open a document, an Access Violation occurs.. and debugger breaks on the code of CFixedAllocNoSync::Alloc() function.. On the callstack, I noticed that this Alloc() function was called by one of the control bars CControlBar::PreTranslateMessage().. I don't know what to adjust or what to change because this is internal to MFC already..

Hi guys!
I am really interested in experimenting with writing a scripting language and an interpreter to execute it. I've never done anything like this before and was hoping you might have some know of some articles/tutorials for beginners. I am hoping that it'll be object-oriented (similar to ECMAScript/Javascript), support debugging, support garbage collection, and be able to bind to native code (DLLs on Windows).
If you could please point me into the right direction or know of any articles/tutorials for beginners, I would really appreciate it.
Thanks

go up to the search box on CP, type in 'script', make sure the drop-box says 'Articles', hit 'Go' - there is a lot of info on this site - maybe not explicitly about ECMAScript, but it'll start you off

Hi all,
I need to build a server with threading pool to handling client request.
Is it better to have ayschronous server connection rather than synchronous
connection, so that the server can have better response or performance ?
Is asynchronous server connection hard to program ?
Thank you
|
|
|
|
|
Doh, synchronous perfoms better, but asynchronous offers much better scalability.
Then, it depends on what you want - if you have only one client, then synchronous will be the choice, if the number of clients is unknowns or more than 2-3, async is the choice.
Async is much harder to code, because humans usually don't think async.
|
|
|
|
|
Thanks !
But why 2-3 clients is the boundary ?
And are there any reference for programming async server ?
|
|
|
|
|
Well, it's not exactly 2-3, it's just the range, where it can be acceptable and because if you have 4 clients, you usually have 5 next day, then 6 and after month you'll find yourself having trouble with 100...
Problem with synchronous access, is that it needs generally one thread per client behavior and then they became a resource hog, because a lot of time is spent by creating/destructing these threads and by switching between them.
Ideal ratio is one thread per one cpu, although this is of course unrealistic, but more threads means more work in the OS, hence less cpu time for application.
look here, at the section internet&networks on codeproject for more details and even tutorials:

Really good question...
Geo states right one regarding one client and multiple client request. I would recommend asynchoronous if you have multiple clients.. But Now you have to think about the right choices of choosing a thread option.
Option 1:
1. You can handle multiple client request in one thread!!! by using windows socket overlapped, or messaging socket communication technologies. Microsoft provides better support to work with one thread but multiple socket connection. I think you can handle maximum of 64 client connections in one thread.. (I may be wrong). But to be careful, this choice won't always good to any solution.. You have to workout whether this technique is suitable for you or not.
2. If you opt for single thread per connection, this seems to be good, but this will screw your application, system performance. Suppose say, your server handles 1000 request at a time, you have to create 1000 threads to handle this.. But still you have choice.. You can use thread pooling, instead of creating a thread each time, you can use existing thread one the connected client disconnected.. Again this is painful approach, but this would increase performance of the system..
3. Mix of option one and Two. Having thread pool + one thread will handle multple sockets
This is really very good to discuss, I would appreciate if you guys add more points to this topic...

Hello,
Are there any standards for designing form or form builder. I need
to write a form designer so that user can design and custom their own
form in the application ? It is fine to write it in c#, but I want to know
if I need to conform to some standards in the market, so to make my application more universal and better compatitibility ?
Many thanks
