You guess wrong, the problem is the original one only, I software "FileSecure" that makes a folder safe, you can read, edit, delete, copy, etc. on that folder on any Win platform and file system and also it should work in safe work.

Hi,
I am developping a new CORBA application from Visual C++.
I reach to create new objects into a server and link their reference, i.e IOR, from a cliente in order to make calls to methods from its remote interface. I do all this using a text tile that the server writes and the client reads in order to get the IOR.
I would like to use a NameService in order to not using that text file and start developping a real remote distrubited application.
My code is the following one, and is the same as described for example by Omni distribution:
--------------------------------------------------------------------------------------
//////////////////////////////////////////////////////////////////////
static CORBA::Boolean
bindObjectToName(CORBA::ORB_ptr orb, CORBA::Object_ptr objref)
{
CosNaming::NamingContext_var rootContext;
try {
// Obtain a reference to the root context of the Name service:
CORBA::Object_var obj;
obj = orb->resolve_initial_references("NameService");
// Narrow the reference returned.
rootContext = CosNaming::NamingContext::_narrow(obj);
if( CORBA::is_nil(rootContext) ) {
cerr << "Failed to narrow the root naming context." << endl;
return 0;
}
}
catch(CORBA::ORB::InvalidName& ex) {
// This should not happen!
cerr << "Service required is invalid [does not exist]." << endl;
return 0;
}
try {
// Bind a context called "test" to the root context:
CosNaming::Name contextName;
contextName.length(1);
contextName[0].id = (const char*) "test"; // string copied
contextName[0].kind = (const char*) "my_context"; // string copied
// Note on kind: The kind field is used to indicate the type
// of the object. This is to avoid conventions such as that used
// by files (name.type -- e.g. test.ps = postscript etc.)
CosNaming::NamingContext_var testContext;
try {
// Bind the context to root.
testContext = rootContext->bind_new_context(contextName);
}
catch(CosNaming::NamingContext::AlreadyBound& ex) {
// If the context already exists, this exception will be raised.
// In this case, just resolve the name and assign testContext
// to the object returned:
CORBA::Object_var obj;
obj = rootContext->resolve(contextName);
testContext = CosNaming::NamingContext::_narrow(obj);
if( CORBA::is_nil(testContext) ) {
cerr << "Failed to narrow naming context." << endl;
return 0;
}
}
// Bind objref with name Echo to the testContext:
CosNaming::Name objectName;
objectName.length(1);
objectName[0].id = (const char*) "Echo"; // string copied
objectName[0].kind = (const char*) "Object"; // string copied
try {
testContext->bind(objectName, objref);
}
catch(CosNaming::NamingContext::AlreadyBound& ex) {
testContext->rebind(objectName, objref);
}
// Note: Using rebind() will overwrite any Object previously bound
// to /test/Echo with obj.
// Alternatively, bind() can be used, which will raise a
// CosNaming::NamingContext::AlreadyBound exception if the name
// supplied is already bound to an object.
// Amendment: When using OrbixNames, it is necessary to first try bind
// and then rebind, as rebind on it's own will throw a NotFoundexception if
// the Name has not already been bound. [This is incorrect behaviour -
// it should just bind].
}
catch(CORBA::COMM_FAILURE& ex) {
cerr << "Caught system exception COMM_FAILURE -- unable to contact the "
<< "naming service." << endl;
return 0;
}
catch(CORBA::SystemException&) {
cerr << "Caught a CORBA::SystemException while using the naming service."
<< endl;
return 0;
}
return 1;

I run the application omniNames.exe with parameters:
omniNames.exe -start 12345 .. . . . .
That seems to work. It runs in console mode, not as a service.
If I execute my server, with the code descrive on top, I get the following exception error:
catch(CORBA::SystemException&) {
cerr << "Caught CORBA::SystemException." << endl;
}
Otherwise, If I replace the following line
obj = orb->resolve_initial_references("NameService");
for that one:
obj = orb->resolve_initial_references("corbaloc:iio:localhost:12345/NameService");
Now, I don't get the same error, I get other one:
catch(CORBA::ORB::InvalidName& ex) {
// This should not happen!
cerr << "Service required is invalid [does not exist]." << endl;
return 0;
Does anybody have any idea what is happening?
Must I run omniNames as a service? and if so, Why?
Do I need other configuration?
I would like to use Omni CORBA distrubution.
Thanks, and pardon for my english ( I am spanish... )

I think that you have trouble locating your nameming server. Did you start up a naming server?

Thanks for answering...
Yes, I think.
I started NameService as follows:
"C:\omni\bin\x86_win32\omniNames.exe -start 12345 -logdir C:\omni -errlog C:\omni\errlog"
It seems I have initialized my NameService at port 12345
I have created my NameService.bat on it and It seems to work. I runs.
The problem is when I run my Server.
Is there anything more I have to do?

Yes, the following things should always be done (with every code you write)
<list> Write code that handles errors where errors can be expected (you did this)
If you find an error don't just print "ERROR" Print as much information as you can. This information often is found in the caugth exception, or can be obtained through some api's
Without that information, many things could be happening. Maybe you run a firewall that blocks your namingserver, etc...

Hi everyone,
in your resources you can set resources for different language. The appropriate language is loaded according to you windows language. Therefor in your resource file you have to add e.g. '#if defined(AFX_TARG_NLB)' for you dutch resources.
Now, I have a database containing a field with strings in dutch in it and a field with its english translations. If the dutch resources are loaded I want to take the dutch field. I no dutch resources are loaded I want to take the english field.
Therefor I want to do this in my cpp file:
#if defined(AFX_TARG_NLB)<br />
m_iLanguage = Dutch;<br />
#else<br />
m_iLanguage = English;<br />
#endif
And use the m_iLanguage variable in my database query for fetching the right language.
I guess AFX_TARG_NLB is defined if the windows version has dutch language, AFX_TARG_ENG when windows has english language. These macros seem to be only defined in .rc files.
So the problem is: the AFX_TARG_... are not defined in my cpp files. How comes and does someone know how to solve it?
µAnother thing, does someone has a solution for this: http://www.codeproject.com/script/comments/forums.asp?forumid=1647&XtraIDs=1647&searchkw=afx_targ_enu&sd=2%2F26%2F2001&ed=5%2F27%2F2005&select=463413&df=100&fr=92935.5#xx463413xx[^]

I’m about to insert a Win32 window in a CWnd (or more specific an COleControl). I’m an old MFC-coder and not really good att Win32 API. After what I understand I should take care of the HWND instance of CWnd…
How do I make the sole Win32 window to stretch over my CWnd… ?
Thanks in advance…

I'm having a problem with the CreateControl method of the CWnd object.
I can create the ActiveX but it seems that the Ctrl-c and Ctrl-v is not forwarded to the Active X but all the general key press works.
When i insert the ActiveX in the OLE test container the Ctrl-c and Ctrl-v works fine.
Please help me.
Thanks

Have you got an accelerator table loaded which has those combinations as a shortcut? If so, you'll have to disable it or remove the combinations you want the control to handle.

no no, i'm not spaming the forum... 
i have the following code :
BOOL CMSILauncherDlg::OnEraseBkgnd(CDC* pDC) {
<font color=green>
CBitmap BackGroundBitmap;
BackGroundBitmap.LoadBitmap(IDB_BGND);
CDC MemDC;
MemDC.CreateCompatibleDC(pDC);
MemDC.SelectObject(&BackGroundBitmap);
CRect ClientRect;
GetClientRect(&ClientRect);
CPoint OriginPoint(0, 0);
CSize BGBitmapSize(BackGroundBitmap.GetBitmapDimensions().cx,
BackGroundBitmap.GetBitmapDimensions().cy);
<font color=blue>for</font> (OriginPoint.y = ClientRect.top; OriginPoint.y < ClientRect.bottom; OriginPoint.y += BGBitmapSize.cy) {
<font color=blue>for</font> (OriginPoint.x = ClientRect.left; OriginPoint.x < ClientRect.right; OriginPoint.x += BGBitmapSize.x) {
pDC->BitBlt(OriginPoint.x,
OriginPoint.y,
BGBitmapSize.cx,
BGBitmapSize.cy,
&MemDC,
0,
0,
SRCCOPY);
}
}
<font color=blue>return</font> 1;
}
the above code doesnt work till the BackGroundBitmap.GetBitmapDimensions() return {0, 0} as size...
if i manually replace the function calls by the actual bitmap size, the function work quite fine (in fact, the bitmaps are not well "mosaic-ed" but spaced - maybe a unit problem).
<font color=green>
CSize BGBitmapSize(BackGroundBitmap.GetBitmapDimensions().cx,
BackGroundBitmap.GetBitmapDimensions().cy);
<font color=green>
CSize BGBitmapSize(190, 187);
<font color=green>
BackGroundBitmap.SetBitmapDimensions(190, 187);
CSize BGBitmapSize(BackGroundBitmap.GetBitmapDimensions().cx,
BackGroundBitmap.GetBitmapDimensions().cy);
does anyone already encountered this problem ?
any suggestions or solutions ?

Use CBitmap::GetBitmap to fill a BITMAP structure. Use BITMAP::bmWidth and BITMAP::bmHeight for the size of the bitmap in pixels.

from the MSDN, they say for CDC::BitBlt :
Parameters
x
Specifies the logical x-coordinate of the upper-left corner of the destination rectangle.
y
Specifies the logical y-coordinate of the upper-left corner of the destination rectangle.
what is called a logical coordinate ? pixels ? or dbu ?
are there any functions to convert pxl <---> dbu ??

logical coords are never dbu. What they are depends on the mapping mode of the DC. See CDC::SetMapMode(). If you do not explicitly set the map mode to something else it will be MM_TEXT and logical coords will be pixels.
Use MapDialogRect() or GetDialogBaseUnits() to convert between pixels and dbu, although I have no idea why you would have to just for displaying a bitmapped background. GetClientRect() will give you the dimensions of your window in pixels.

An alternate method to tiling a bitmap over a window is to use CreatePatternBrush[^] to create a brush, and then use FillRect[^] to fill the window. This approach automatically takes into account the size of the bitmap, the window, and so on.

but i don't want to fill, i want to mosaic my bitmap...
thanks anyway for your answer

good morning everybody,
As some of you might have sees yesterday, I have some trouble with reactivating an already existing instance of a program of my own which lost the focus.
Mr DavidCrow suggested me to use EnumWindows(), but as i am not familiar at all with CallBack functions, i'd be grateful if some of you post a little example of use of the this functions.
the best would show how to get the handle of a particuliar windows...
thank to all of you

With CallBack, You can also use FindWindow and FindWindowEx to Enumerate all Visible desktop Window.
here little Piece of Code to do that:-
BOOL NMPEnumWindows(CStringArray *arWindowsName,CPtrArray *arhWnd)
{
HWND hWnd,hWnd1=NULL;
CString Str;
char lpString[201];
hWnd=::GetDesktopWindow();
do
{
hWnd1=::FindWindowEx(hWnd,hWnd1,NULL,NULL);
::GetWindowText(hWnd1,lpString,200);
Str.Format(\"%s\",lpString);
//select only visible desktop window
If((::IsWindowVisible(hWnd1)==TRUE)&&(Str!=\"\"))
{
arhWnd->Add((HWND)hWnd1);
arWindowsName->Add(Str);
}
}while(hWnd1!=NULL);
return TRUE;
}

I need help for two questions , the subject defines the first one.
1)
I created a static splitter window with two horizontal panes. When i click on a particular pane that one becomes active and the other one inactive, which is obvious. But my application requires that only the second one should be active forever. Even if i click on the first pane the control should again return back to the second pane. This may contradict the very idea of using a splitter window, but there seems to be no other option. Can anyone please help?
2)
I use the splitter window so that i can display text in the first pane and display bitmaps (on which i perform image processing operations) in the second pane. Once the text is displayed in the first pane i want it to remain there forever(as long as the application runs). All the operations are to be performed in the second pane without disturbing the first pane.
If anyone can suggest a better way than using splitter windows please let me know.
Thank You

Whenever I do a build, say a Release build, the wrong referenced assemblies (the Debug versions instead of the Release versions) get copied to the target directory. In fact, the Debug versions of the DLLs will get copied to the target directory in both Release and Debug configurations - usually. I can get Visual Studio to reverse this behavior by removing the DLL project refrences and re-adding them while in Release build configuration. Now the Release versions of the dll assemblies will be copied to the target directories during both Release and Debug builds. Does anyone have any idea what is going on here???
Note that, in spite of this weird behavior, when I view the properties for a particular assembly referenced in any given project, the file location is always correct; that is, it will be in the /Debug folder in Debug configuration and in the \Release folder in Release configuration.

if you want it to overwrite the old link version every time you run a new compile?

Don't know exactly what you mean, but link incrementally off?
|
|
|
|

What's the use of that. The compiler will pruduce the same object files for the files that havn't changed. If you change some code the old linke executable will become overwritten automatically!
