Thanks in Advance

What do you mean by 'data' ? Could you be more explicit please ?
|
|

|

Suppose if i enter a string in an edit box MFC GUI, i want to get that string to win32 console application.

You can write the data to a file that the console app can read, pass it to the console app's command line (this assumes you are using CreateProcess() or ShellExecute() to run the console app), or send the data to the console app's standard input handle.
Without more details on how the two apps are related (i.e., how they are started and communicate), that's all I can offer.

Hi David,
Thanks for your reply.
Excatly the same i want. How to communicate the applications.

Hello there.
I have a third party libraries that is expected to deliver back parameters encoded as wide char strings.
so in my client application I just intercept and expolit their values :
void onDataFromDLL(std::wstring myStr){
//
}
my client app is MFC dlg with unicode defintion.
is there a way from there to tell that myStr content is actually wide char encoded ??
The reason is becuase of many weird results I get.
Thank you in advance.

Usually 'the weird results' test's failure provides an hint. 
BTW how do you call such library (what is the API exposed)?

The API exposed is in form of export classes with virtual handlers to be overriden.
In fact I am trying to integrate a SAX parser (from Poco C++ project).
The parser has a contenthandler with virtual methods that send back the xml tags and properties encountered.
The library can be compiled in two different ways, either by defining a certain _xxx_UNICODE symbol or not. The consequence is on the definition of a certain library exported type : XMLString (either an std::string or an std::wstring accordingly).
The parameters I collect and try to exploit in the virtual methods of the derived classes are mostly of type XMLString.
for instance :
void startElement(const XMLNode & localName..); is a virtual methods that is called each time tghe parser encounters a new XML tag.
if Poco's XML library is compiled without the _xxx_UNICODE symbol then there is no problem trying to play with the received parameters and comparing them against std::string variables content,etc
in the
The problem is when the library is compiled as unicode and that I am expected to receive the parameters content as wide chars. :
displaying the content of an XMLString (=std::wstring) in a TRACE or AfxMessageBox, or evebn trying to compare it against a value that is supposed to equal it always fails..

How do you display the string content (i.e. are you doing a UNICODE build of your application)?

This is how supposing localName is of type XMLString (ie std::wstring) which I want to display :
CString str;
str.Format(_T("%s"),localName.c_str());
AfxMessageBox(str);
(or even AfxMessageBox(localName.c_str()); )
my application is Unicode so the %s will cause the paramter localName in ::Format to be interpreted as widechars.
neverthless I get unregnizable things in screen.
Neverthless I now discover that when I put %S then I can understand what is displayed.
Since %S in context of Unicode app means to interprete the param as simple chars then my conclusion
is that the third party library is no doing anything like actually formatting results in wide chars.
I'm not sure of my conclusion..but the following is taken from MSDN regarding the printf :
[
S
String
When used with printf functions, specifies a wide-character string; when used with wprintf functions, specifies a single-byte–character string. Characters are printed up to the first null character or until the precision value is reached.
]
Anyway..well Poco..well..

Hello all.. I don't know how to achieve this but i guess that's possible..
I've one dialog box and a picture control on it. I'm using CxImage Class to load and display PNG on that picture box.. Till now everything is good.. Now i've to show that PNG in a way so that it look like it's drawn on desktop screen. So for that i make my dialog transparent.. But making dialog transparent makes my picture control transparent. So no PNG is being shown. How do i overcome this problem...Or is there any way in CxImage Class to show PNG directly on desktop screen by taking DC of desktop screen..
Here is code to make dialog transparent..
SetWindowLong(hWnd,GWL_EXSTYLE,GetWindowLong(hWnd,GWL_EXSTYLE)^WS_EX_LAYERED);
SetLayeredWindowAttributes(hWnd,RGB(0,0,0),0,LWA_ALPHA);
Thanks all...

Look into "UpdateLayeredWindow" if you want to use per-pixel blending.

I think I told you yesterday did you see GetDesktopWindow?
|
|
|
|
|
Yes i did.. And that'll be great if i show my PNG on desktop rather than dialog box.. I did something like this..
BeginPaint (hWnd, &ps) ;
HWND hDesktop = GetDesktopWindow();
HDC hdc = GetDC(hDesktop);
CxImage image("E:\\My_Prog\\FINAL_PNG\\Res\\Test.png", CXIMAGE_FORMAT_PNG);
BOOL iReturn = image.Draw(hdc, 50, 50);
EndPaint (hWnd, &ps) ;
I get the handle of desktop and DC also.. But it didn't draw the PNG. What am i doing wrong?
|
|
|
|
|
Its working for me of course like this:
HWND hDesktop = ::GetDesktopWindow();
HDC hdc = ::GetDC(hDesktop);
CImage image;
image.Load("f:\\1.png");
BOOL iReturn = image.BitBlt(hdc, 50, 50);
|
|
|
|
|
Ok so you're using BitBlt.. But when i use image.BilBlt it says.
"error C2039: 'BitBlt' : is not a member of 'CxImage'"
Obviously there's no member called BitBlt in CxImage Class.. So do i need to use CImage??? Does BitBlt comes under Cimage??? Or can i use BitBlt on CxImage??
|
|
|
|
|
Yeah because I use of CImage class not CXImage article.
|
|
|
|
|
Alright.. Anyways i manage to Draw the PNG on desktop screen.. But the problem is that it get erases whenever any window is dragged on it.. Is there any way to refresh it???

Please don't shout.
It looks like a (simple) homework assignment (we won't do it for you, but we may help). What have you done so far? What is your trouble about?

You did not get the response you were hoping for here so you asked the very same, unedited question on a different forum. Amazing.
