Re: Adding ActiveX Control Container to Win32 Window

HWND passed in

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.

Implementation leakage - when Release returns 7, that shows there are still 7 references to the interface being held somewhere[^].

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):

If you don't use the IUnknown pointer for anything, then just pass in NULL instead of &pUnk - you don't need the pointer.

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.

Appending a number to the end of a string to display in GLUI_ EDITTEXT_TEXT Box?

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.

//My variables
int Cnum = 1;
int Pnum = 1;
char Cube[sizeof(GLUI_String)] ={" "};
char Plane[sizeof(GLUI_String)] ={" "};
char Name;

//my glui edittext 
Name1 = subwin->add_edittext( "Name", GLUI_EDITTEXT_TEXT,&Name); 

//my callback functions
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++;
}

How to save javascript file

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];

Name = Plane;

and

Name = Cube;

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

MrKBA26-May-09 9:12

26-May-09 9:12

yes i see them, but i couldn't used GetItemData() like i need.

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);

MrKBA26-May-09 9:33

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

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

Row | Name | Age
X X-name X-age

what i need is to get the
Row = X
Name = X-name
Age = X-age
