Yes, I just installed the SDK.
But I get this error:
c:\program files\microsoft visual studio\vc98\include\iphlpapi.h(183) : error C2065: 'PMIB_ICMP_EX' : undeclared identifier
Any ideas.
Thanks

It's solved including the right directories in tools / options / directories.
Thanks

Is it possible to do it ?
I created a CButton in a dialog, and made it a CBitmapButton :
CBitmapButton myButton;
...
DDX_Control(pDX, IDC_OPTION_PANEL_CHECKBOX, m_myButton);
...
BOOL myDialog::OnInitDialog()
{
CDialog::OnInitDialog();
myButton.SetButtonStyle( BS_AUTOCHECKBOX );
myButton.LoadBitmaps(IDB_SHOW_HIDE_OPTION_PANEL_UP,IDB_SHOW_HIDE_OPTION_PANEL_DOWN );
myButton.SizeToContent();
...
}
If I do SetButtonStyle( BS_AUTOCHECKBOX ) I loose the bitmaps and the button becomes a simple checkbox button.
Did I miss the obvious ?
Thanks.
Max.

Hi,
I want to use this control in my win32 program (not mfc) through rc file.
When I use this control, the dialog box is not displaying.
Can anybody help please?
RC file excerpts:
CONTROL "",IDC_LIST1,"SysListView32",LVS_ALIGNLEFT | WS_BORDER |
WS_TABSTOP,81,10,60,50
Thanks in advance.

WHy is this happening?
I have:
CImage & ImageRemus = m_PaletteMap[m_PalRemus];
If I put a breakpoint at this line and step in ,it crashes if I try to advance to next line of code (step over).
But if I put a breakpoint in the destructor of my CImage class, and say run to next breakpoint from this first breakpoint, it steps into the destructor!!!! (It crashes there).
Question is why is it stepping into the destructor?
Appreciate your help,

There is not enough information, so I am going to guess.
1. member at position m_PalRemus does not exist.
2. CImage default constructor does not initialize object properly OR you did not overwrite copy constructor.
Could you show the whole function and exact declaration of the map. The declaration of CImage would help too.

Hi Alex,
I stil dont know why it went into the destructor. But I found out that I hadnt initialized a member in the constructor, so it was pointing to some invalid address. Then in the destructor I was having it delete that pointer if it existed. It did exist because it wasnt initialized and then it tried to delete it. The big mystery is --- why did it even go into the destructor in the first place? After i fixed the error (omission), and put breakpoints in the destructor, the program never did venture into the destructor .....puzzled.
Appreciate your help,

Here is simplified explanation
std::map<key, type=""> operator[]:
1. check if member at Key position exist (same as calling map::find(Key))
2. if does not exist create new value
a. Create temporary object of Type (call to Type::Type() constructor)
b. Copy the temporary obect to the position [Key](call to Type::Type(const Type &) constructor)
c. Destroy temporary obect(call to Type::~Type())
3. Return Type& to the element at Key position

Thats really clarified the process to me. Thank you so much....now it makes perfect sense!!

the definition of std::map<>::operator[] says it returns value of insert(value_type(key, T())).
this value_type(key, T()) creates temporary T object (CImage in your case) using default constructor. This temp object is destroyed when operator[] exits, therefore the destructor is called.

here is my problem:
<br />
<br />
Class test<br />
<br />
void test::showmsg<br />
{<br />
AfxMessageBox(m_msg);<br />
}<br />
<br />
function thread<br />
<br />
UINT testThread(LPVOID param)<br />
{<br />
?????? ctrl = class mainclass control ??????<br />
<br />
for (int i = 0; i < 100; i++)<br />
{<br />
ctrl->m_msg.Format("%d", i);<br />
ctrl->showmsg();<br />
}<br />
<br />
return 0;<br />
}<br />
<br />
this is a simple example of what i want to do, the thread is gonna be a connection with a network.

When launching the thread, give this as parameter.
Then with a CMainDlg *ctrl = (CMainDlg*)param; (instead of the line where you put ?????)everything should be fine.
~RaGE();
|
|
|
|
|
You should pass a pointer to your class test when calling AfxBeginThread, supplying the pointer as second parameter.
in test, where starting your thread:
AfxBeginThread(testThread, (LPVOID)this)

How can we insert a gif file (or any image file ) in a dialog window ?
|
|
|
|
|
If it is a bmp, you have lots of possibility (Creating a CStatic, and load your bitmap in it with help of LoadBitmap());
For gif or other, you'll have to get a specific loader.
~RaGE();

App runs fine when just executed. IF i put in a breakpoint and step in:
It crashes at the point where I create a map:
CImage x;
MyMap["abc"] = x;
(alternatively I did
CImage &x = MyMap["abc"]; - same effect )
The debug window says: Invalid Address specified to RtlFreeHeap
Looked it up on the web...not much help.
The assembly is pointing to an int 3 instruction
The call stack is in NTDLL.
Its in delete() in AFXMEM.cpp ( I think thats the name of the file where the call stack points to...)
Appreciate your help,

seems that something tries to free (delete, delete[], free(), etc) a memory block which is not valid or already freed.
You might have a stack corruption, or your map class tries to free the "abc" string. There are a lot of possible causes.

Yup. I found that I hadnt initialized a pointer in the constructor, and then was trying to delete it instantly if it exists. Of course it existed with garbage (unintialized) in it....so it was unhappy. Many thanks for the remote - hit the nail on the head debugging....

hi. i am working on a Game,and ive got a little problem.
my problem is in the below code :
<br />
Canalyze_b * ab= new Canalyze_b();<br />
ab->Create(IDD_AB,this);<br />
ab->SetWindowPos(&CWnd::wndTop ,140, 140, 300, 300, SWP_SHOWWINDOW);<br />
ab->ModifyStyle( WS_POPUP ,WS_CHILD,0);<br />
ab->ShowWindow(SW_SHOW); <br />
ab->analyze(NULL);<br />
<br />
Game s;<br />
s.analyze();
the s.analyze() operation will take time about 10 or 15 seconds. and i have to show the results of caculation during the operation. for example in a Simple EditBox.
for example in analyze() i have :
<br />
void Game::analyze(){<br />
<br />
while (n<100) {<br />
----> Show results on a Simple EditBox on dialog<br />
----> Calculate the next Position<br />
}<br />
}
my problem is that during the operation nothing Shown in the EditBox 
and when the Operation ends only the last Result Will Shown on the Dialog !!
i think it's coz the Calculation function will takeover Showing results on the edit box and don't let it to occure. So is there any Way to Show Without any problem !
thanxxx

Sure! Create your own worker thread. Then call it with AfxBeginThread(YourThread, YourParam). For easy calling functions of your dialog pass a pointer to your dialog as YourParam (think it should look like
UINT YourThread( LPVOID pParam );
...
AfxBeginThread(YourThread, (LPVOID )ab)
).
Now you can call any function on your dialog in your thread
UINT YourThread( LPVOID pParam ){
Canalyze_b * ab= (Canalyze_b *)pParam;
ab->DoAnything()
}
That's it!
