Hi,
i m reading value from ini file and reading into CString.values are stored in japanese language in ini file.now when i convert CString into WCHAR it turns into garbage value.any solution?
|
|
|
|
|
|
CString name;
WCHAR disname[100]={0};
name= m_IniReader.getKeyValue(str,"VIEWNAME");;
wcscpy(disname, A2W((LPCSTR)name));
like this?
|
|
|
|
|
Try this 
WCHAR disname[100]={0};
CStringW name;
name= m_IniReader.getKeyValue(str,"VIEWNAME");
wcscpy(disname, (LPCWSTR)name.GetBuffer(100));
MessageBoxW(NULL,disname,disname,MB_OK);
name.ReleaseBuffer(100);

No, calling GetBuffer is really a very bad practice. You shouldn't do that, the CString class already provides cast operators so there's no need to call GetBuffer !
And the the case is probably no needed neither, but that depends how the project was compiled (UNICODE or not).

i heard a lot of time calling GetBuffer a bad practice,
why do so?

GetBuffer (as the name suggests) exposes the internal buffer of the CString object.
Moreover you must remember to call ReleaseBuffer when you've done with it. Most of the times, you really don't need to call it.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Because if you read the documentation of the function, you will see that you get a pointer to the internal buffer of the string and that you HAVE to call ReleaseBuffer afterward (which will be often forgotten). Furthermore, why would you use GetBuffer, while the CString provides a cast operator which returns you the same thing ?
Calling GetBuffer can lead to mistakes if you forget to call ReleaseBuffer.

Thanks, I didn't know that

Did u check the whether you are getting the japanese text in CString?
And i hope its a UNICODE build.

yes i m getting japanese text in CString.

Please check whether _UNICODE preprocessor is added in your project setting.

CString name;
WCHAR disname[100]={0};
name= m_IniReader.getKeyValue(str,"VIEWNAME");;
wcscpy(disname, A2W((LPCWSTR)name));
Use this code. And make sure that your project build support UNICODE.

Hi,
My application is a MDI application and looks like,above the frame(mainframe caption bar)one modeless dialog always displaying.
My problem is in order to move the applicaton to secondary monitor,we normally do- Restore down the window,and clicking on the blue caption bar we drag the window and move to secondary monitor.
But my application always having dialog on top,i cannot click on the caption bar,so i cannot move to secondary monitor.
So pls anybody of you kindly explain how can i move that.

You could define a "hot place" on your dialog
to process the following reactions there on :
- WM_LBUTTONDOWN to set a "hot place flag" and the mouse capture
- WM_MOUSEMOVE to move the dialog and the main frame, if the "hot place flag" was set
- WM_LBUTTONUP to reset the "hot place flag" and release the mouse capture
virtual void BeHappy() = 0;

I use C++ to create two XLL's A.xll and B.xll. A function in A.xll requires B.xll. If I compile A.xll with a project dependency on B.xll, then Excel does not register the functions in A.xll. If I compile A.xll without the project dependency and only include B.lib, then all functions are registered.
What is the reason? Is it a bug in Visual Studio compiler or some other issue?

Hi,
The following is TCP/IP packets collected by Wireshark:
34 16:09:29.056911 10.10.10.7 10.10.10.100 TCP 49167 > amiganetfs [PSH, ACK] Seq=55 Ack=1567 Win=64240 Len=6
35 16:09:29.193003 10.10.10.100 10.10.10.7 TCP amiganetfs > 49167 [PSH, ACK] Seq=1567 Ack=61 Win=5632 Len=1
36 16:09:29.386529 10.10.10.7 10.10.10.100 TCP [TCP Retransmission] 49167 > amiganetfs [PSH, ACK] Seq=55 Ack=1567 Win=64240 Len=6
What is happening here is 49167 sends 6 bytes to amiganetfs which acknowledges them and sends one byte back, then 49167 resends the packet 34 as if it didn't receive the ack (but it was received and picked up by Wireshark). It seems that ack was ignored by 49167. Any idea why it's happening so?

|
|
What does this have to do with C++  ?
|
|
|
|
|
It may be possible that the ACK did not reach the other side. Capture on both the sides and see.
BTW, Nobody will be able to help you further on this if you don't post
the exact code which transmits the packet and receives the packet.

I am new to c++. I need to use a vector to store array with flexible length. That is in a loop, for each index i, the length of the array x[i] is change.
Please give me the declaration and code fragments.
Thanks

A simple google[^] search is the best help sometimes, the first hit seems to be promising already.

Sounds like, in the most general case, you're after a std::vector of std::vectors:
typedef std::vector<int> InnerType;
typedef std::vector<InnerType> OuterType;
OuterType my_array;
Or you can construct the type directly without the typedefs (I'd use the typedefs personally):
std::vector<std::vector<int> > my_array;

try it this way
vector<int> countVal;
vector<int> ArrInts;
#This can be a loop to assign values of flexible length .I have kept it simple
countVal.push_back (12);
countVal.push_back (13);
countVal.push_back (14);
ArrInts.assign(countVal.begin(),countVal.end());

Thank you!
I am trying to do the following within a function if it is works:
//
for ( int i=0;i<nh;i++)
{
="" int="" n="d[i]/10;
" vector="" <float=""> z[n];
//
for ( int j=0;j<n;j++)
{
="" xc="10*j*" x[i]="" d[i];
="" yc="10*j*" y[i]="" z[j]="SEVAL3D(n_points," xc,yc,x_topo,="" y_topo,="" z_topo);
="" if(zmax<z[j])="" {zmax="z[j];
" imax="j;}
" }
please="" advise="" if="" i="" can="" use="" a="" vector="" in="" this="" way?
thanks
