I was saving the reference in memory and calling release just before the window is closed.
But now...
I changed it to call Release().
Here is how I am creating the control (changed to use a url):
VOID CreateControl( HWND hwnd )
{
HRESULT hr = CoInitialize( NULL );
printf( "CoInitialize(NULL) -> hr=[0x%x]\n", hr );
printf( "Create AtlAxWin Begin...[0x%x]\n", hwnd );
BOOL rslt = AtlAxWinInit();
printf( " AtlAxWinInit() --> %d\n", rslt );
IUnknown *pUnk = NULL;
hr = AtlAxCreateControl( OLESTR( "http://www.microsoft.com" ), hwnd, NULL, &pUnk );
printf( "AtlAxCreateControl(...) -> hr=[0x%x] : pUnk=[0x%x]\n", hr, pUnk );
ULONG relRslt = pUnk->Release();
printf( "Release() -> %d\n", relRslt );
}
Here is the output:
CoInitialize(NULL) -> hr=[0x0]
Create AtlAxWin Begin...[0x150dac]
AtlAxWinInit() --> 1
AtlAxCreateControl(...) -> hr=[0x0] : pUnk=[0x3233e30]
Release() -> 7
Although the "Release()" is returning 7, it appears to be working... ONLY if I send WM_CLOSE to the HWND prior to closing the window.
However, I don't think I want to close the HWND in all cases.
Is there a way to just remove or unload the control, so the HWND can be reused?
In fact if I use Adobe Reader via specifying c:\test.pdf it works until I shutdown the application.
At the end of the app I get an access violation:

I'm guessing the java vm doesn't know about the win32 HWND being "closed"... but that's just a guess?

However... perhaps I could create a child window which is just a child to the HWND passed in?
Perhaps that would prevent the jvm crashing at the end?

What is that HWND? Is it the dialog HWND? Because really, it needs to be the HWND of a window whose ONLY responsibility is containing the ActiveX control. As I said, what I did was to create a STATIC control with no text, then pass its HWND to the ActiveX creation function. Then, when the dialog closes, it closes the STATIC's window for me, I don't need to do anything.

The HWND is the handle for a java.awt.Canvas.
I'm getting the HWND as is documented in the jni docs which is shown here:
Implement the C++ native code[^]
The create function you're referring to is AtlAxCreateControl( OLESTR( "http://www.microsoft.com" ), hwnd, NULL, &pUnk ), correct?
What do you mean "with no text"?
So it looks like I need to create a new window as a child of the HWND I'm getting from the java.awt.Canvas and create the control on that window instead of the one from java...?
(thanks again for your help with this)

I mean I didn't add any text to the static text control - probably of little relevance.

Yep - I used a different first parameter (I passed the progid of the calendar ActiveX control - but that (again) is of little relevance.

That's what I'm suggesting.

I will try passing NULL.
I am confused as to why it was returning 7 instead of zero, but I assumed it was because at least the control container and control itself had references to it.
I will take a look at the link you sent.

What I am trying to do is when I click a button it draws a cube or whatever and displays the name of the object in a
GLUI_EDITTEXT_TEXT box.I also want to append a number to the end of the object name and increment the number each time a new object is drawn. I have everything working ok except the name and number will only display one character at a time in the textbox and increments the position each time the draw button is pushed. Much Thanks to anyone who will/can help with this. Jody Bush
Below is part of the code I have for this thing.
int Cnum = 1;
int Pnum = 1;
char Cube[sizeof(GLUI_String)] ={" "};
char Plane[sizeof(GLUI_String)] ={" "};
char Name;
Name1 = subwin->add_edittext( "Name", GLUI_EDITTEXT_TEXT,&Name);
if(control == DRAWPLANE_ID){
drawplane = true;
sizex = 1.0;
sizey = 1.0;
sizez = 0.0;
itoa(Pnum, Plane, 10);
sprintf(Plane,"Plane %d",Cnum);
Name = Plane[Pnum];
Name1->get_text();
Pnum++;
}
if(control == DRAWCUBE_ID){
drawcube = true;
sizex = 1.0;
sizey = 1.0;
sizez = 1.0;
itoa(Cnum, Cube, 10);
sprintf(Cube,"Cube %d",Cnum);
Name = Cube[Cnum];
Name1->get_text();
Cnum++;
}

I think your problem is that you're only passing in one character to the add_edittext call. I don't know what the signature of the method is, but &Name can only refer to a single character (and then, so long as a coincidence of code generation puts zero bytes on the stack.
Anyway I think the problem would probably be solved by
- Declaring Name as
char* Name; - Changing how you assign Name, from
Name = Plane[Pnum];
and
Name = Cube[Cnum];
to
Name = Plane;
and
Name = Cube;

That's a very good question. Good luck with it.

Are you referring to the SetItemData() and GetItemData() methods?

Why not?

i have some difficulties in the returned data.i need to get it in text format to insert them into xml file for example.

It's the exact same data set with SetItemData().
TCHAR *pszBuffer = new TCHAR[12];
_tcscpy(pszBuffer, _T("Hello World"));
m_list.SetItemData(nItem, (DWORD) pszBuffer);
...
pszBuffer = (TCHAR *) m_list.GetItemData(nItem);

how do you use it ?
for example :
YourData* pData = new YourData;<br />
MyList.SetItemData( iIndex, (DWORD_PTR)yourdata);
...
YourData* pData = NULL;<br />
pData = (YourData*)MyList.GetItemData(iIndex);

|
|
so how can use it to retrieve data in text format?

show us the code with the SetItemData.

It's simply a pointer to someplace in memory. How it's interpreted (e.g., char*, int*, class*, is up to you.

Are you talking about GetItemText()?

A stringtable resource?
