i have a bunch of CSplitterWindows, 2 CSplitterWindows and a CHorSplitterWindow, organized like this:
<br />
+----------------------------------------+<br />
| || |<br />
| || |<br />
| || |<br />
| || |<br />
| || |<br />
|========================================|<br />
| || |<br />
| || |<br />
| || |<br />
| || |<br />
| || |<br />
+----------------------------------------+<br />
with some hackery i made the two vertical splitters stay together, to simulate a 4 way splitter. the problem is when the vertical splitters are moved to the left, the left panes don't recieve WM_SIZE, and when the horizontal splitter is moved up, it doesn't send WM_SIZE to the upper pane. all windows recieve WM_SIZE properly if the splitters are moved right, or down. is this a glitch in ATL or a problem of mine? either way, how would i go about fixing it? i assume if its ATL's problem, i have to derive two new classes and send WM_SIZE from my new classes?
oops, diagram got messed up, here is the code i use to set up the panes:
m_HorSplitter->SetSplitterPane(SPLIT_PANE_TOP, m_TopSplitter->m_hWnd);
m_HorSplitter->SetSplitterPane(SPLIT_PANE_BOTTOM, m_BottomSplitter->m_hWnd);
m_TopSplitter->SetSplitterPane(SPLIT_PANE_LEFT, m_Views[0]);
m_TopSplitter->SetSplitterPane(SPLIT_PANE_RIGHT, m_Views[1]);
m_BottomSplitter->SetSplitterPane(SPLIT_PANE_LEFT, m_Views[2]);
m_BottomSplitter->SetSplitterPane(SPLIT_PANE_RIGHT, m_Views[3]);

Hello,
I have a byte array in dialog object on ATL project, and i want to draw the image that represent the bytes array to my dialog.
Threre is any Article that can help me to draw the picture to the client device context? becuase i did it, but i don't see any picture.
Any information about this issue will help...
Thank's alot,
Itay.

Hi,
Are you drawing in the WM_PAINT handler or just using a CClientDC inside some function? Maybe during dialog initialization?
You should draw in the WM_PAINT handler if you want your drawing to be permanent, otherwise the next time window is updated your drawing will be lost.

Hi Guys,
I have a small doubt..In the following code im creating a window and then displaying as modelless using ShowWindow..
<br />
CMyWindow wnd;<br />
RECT rect;<br />
rect.top=0;<br />
rect.left=0;<br />
rect.bottom = 0;<br />
rect.right = 0;<br />
wnd.Create( NULL,rect, _T("Hidden_Window"),WS_OVERLAPPEDWINDOW);<br />
wnd.ShowWindow(SW_HIDE);<br />
CMainDlg dlgMain;<br />
if(dlgMain.Create(wnd.m_hWnd) == NULL)<br />
{<br />
ATLTRACE(_T("Main dialog creation failed!\n"));<br />
return 0;<br />
}<br />
<big>dlgMain.ShowWindow(nCmdShow);</big><br />
<br />
MainDlg is a child of Wnd(which is hidden)..Now this works fine but the problem is that now i want it as Modal Dialog..So if i replace ShowWindow by DoModal
I get assertion failure saying that handle of created window is null..
So any idea..
cheers,
Super

I don't know if this applies to your code, but usually with modal boxes, the only thing you do is call .DoModal(). You don't create the window yourself, hence the ASSERT failure.

Netmeisters,
I am trying to do something which should be simple. Using Visual C++ I want to create a map containing an STL string as a key and my own type as a value.
#include <string>
#include <map>
#include <iostream>
using namespace std;
map<string,CReport>slips;
Then to add a pair to the map:
string str;
pair<map<string,CReport>::iterator, bool> ret =
slips.insert(map<string,CReport>::value_type(str,report));
But this produces a host of error messages that I've included below.
Can't figure these out at all.
Any assistance much appreciated.

Ummm... You sure the error is where you think it is? Try compiling the following sample (which works fine in VC++ 6.0):
#include <string>
#include <map>
#include <iostream>
struct CReport{};
using namespace std;
map<string,CReport>slips;
int main()
{
string str;
CReport report;
pair<map<string,CReport>::iterator, bool> ret =
slips.insert(map<string,CReport>::value_type(str,report));
return 0;
}

Well, if I comment out
pair<map<string,CReport>::iterator, bool> ret =
slips.insert(map<string,CReport>::value_type(str,report));
I don't see the error messages.
Maybe I should mention that this is part of a fairly complicated thing. It is part of a palm conduit lib which is linked against openssl libraries.

Joaquín's example builds fine for me with VC.NET 7.0.
I'm not entirely sure, but I think that the compiler is failing to find a suitable 'operator<' for std::string (which is of course normally a typedef for std::basic_string< char >).
I can replicate your error by removing the #include <string> line. Are you sure you haven't actually got '#include <string.h>'?
Examining the preprocessed output (use the C++/Preprocessor/Generate Preprocessed File option) shows that std::string and std::basic_string are defined in the internal header file <xstring> but that the operators are defined in <string>.
Ensure that <string> is included, and you should be fine.
The overload of operator< that takes two basic_string parameters (with matching template arguments) in this implementation is a namespace-scope template function, defined at line 125 of <string>.

Yes, you are right, the problem was a missing include. In this program I have to do some C style string handling, so I had #include <string.h>. I thought I also had #include <string>, but I didn't. Apologies to all for my stupidity, and thank you for your assistance.

Just in case it happens again:
You can see the instantiation stack of what's being compiled after the error message in the 'see reference' lines. This shows the function that VC had selected to instantiate for the previous one. Working back along this stack we see that it was trying to compile std::map< std::string, CReport, std::less< std::string >, std::allocator< blah > >::insert(). In trying to compile that, it needed to instantiate an internal class member std::_Tree< blah > etc. The compiler lists the lines at which it needed to instantiate something else. From this we can see that it needed to locate an operator< to compare two std::strings. From that I deduced that somehow the appropriate operator wasn't being found.
This is a big improvement over VC6, which doesn't tell you _why_ it's trying to locate such a routine.

Hi, everyone!
Please look at the sample codes below:
Output:
--------
12
2
Null is appended!
0
--------
Source code:
--------
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
char input[] = "12\n3456789\n123456789";
char output [3];
istringstream is (input);
while (is.getline (output, sizeof (output), '\n'))
{
cout << output << endl;
cout << strlen (output) << endl;
if (0 == output [strlen (output)])
{
cout << "Null is appended! " << endl;
}
cout << unsigned int (output [strlen (output)]) << endl;
}
return 1;
}
--------
But when I change "char output [3];" to "char output [0xff];", the output
is OK! Tt is,
--------
12
2
Null is appended!
0
3456789
7
Null is appended!
0
123456789
9
Null is appended!
0
--------
I have made a reference to MSDN and failed to find any answers.
Who can explain the reason?
Thanks in advance,
George

3 characters isn't enough to hold the longer line, 255 is.
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

|

Thanks, Tim buddie!
Can you explain me the internal reason why the
loop only executes one time when the sizeof
buffer is 3?
regards,
George
|
|
|
|
|
This is my guess:
On the second iteration, it needs to place the line containing "3456789" into the buffer you supplied. Since the buffer is too small, it returns false. Thus your loop terminates.

Hi, i dont have much (actually any) experience using ActiveX controls, Say i want to use one like the WinSock Control, or maybe the MSFlexGrid, on my application, How do i do it?, can someone point me in the right direction?
Thanks!
|
|

There are visual ActiveX controls, and windowless ActiveX controls. I assume you are talking about visual controls.
Once the WTL setup is installed, copy the WTL class wizard (AtlApp60.awx + setup.js) files in the Microsoft Visual Studio \ Common \ MSDev98 \ IDE \ Bin.
Then two new project templates should appear when you create new projects.
Choose ATL/WTL App Wizard. In the wizard pages, be sure to check "ActiveX controls".
Once done, go into the resource tab, open a dialog box, right-click on it and choose "Insert Active Controls". You are done!
Technically speaking, a WTL dialog that intends to support ActiveX controls derives from the CAxDialogImpl base class. Which is what you automatically get by checking the appropriate box in the WTL wizard.

Thanks for your answer!, if i may bother you with just another question, Say i use the Winsock control, how do it "control it"? what i mean is, how do i programatically set its properties, recive notifications from it, etc??
Thanks for your patience! i have some WTL and W32 API experience, but like i said, cero experience in ActiveX!

1. import the type-library
2. create a running winsock object instance
3. use it
Code is as follows :
1. insert this line in your precompiled headers :
#import "C:\WINNT\System32\MSWINSCK.OCX"
2. add this code in your .cpp :
MSWinsockLib::IMSWinsockControlPtr wscks(_uuidof(MSWinsockLib::Winsock));
3. use intellisense to call methods as they appear in intellisense
wscks-> (intellisense!) ;)
