Hey

Thanks. I solved it. I removed the WS_EX_CLIENTEDGE in the PreCreateWindow function from both the MDI child frame AND the view. I stumbled on that by accident. Seems to work fine, but i have no clue why the client edge has to be removed from both parts of the framework.

well.....
u have to override the OnSetCursor function!!!!!
just calling it wont help!!!!!
add the WM_SETCURSOR.....
then in that function..... Smile | :)

remove the return statement and replace it with return TRUE;
eg:
bool EXAMPLE::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
....
...

....

~~return CDialog::OnSetCursor(pWnd, nHitTest, message);~~
return TRUE;
}

now add the code where u want to add it ......
SetCursor(AfxGetApp()->LoadStandardCursor(IDC_WAIT));

hope that helpz!!!!!

what if classes need each other?

hiho@ll

just wanted to know what to do if i have 2 classes
class example1
class example2

to use the class example1 in example2 i use #include "exmple1.h" in the example2.h

but then i want to program a function in example1 which uses example2

if i add #include "example2.h" in example1.h i get a compiler error in example1.h

syntax error: identifier 'example2'

i understand why this error occurs
but how i make a workaround?

thx

Re: what if classes need each other?

You just forward-declare example 2:

<br />
// in example1.h<br />
<br />
class example2;<br />
<br />
class example1<br />
{<br />
public:<br />
....<br />
example2* pex2;<br />
}<br />

but as you can see, you can only use pointers to the forwarded class, not the class itself.

Cheers
Steen.

well u c u have example1 class and example2 class,u cant interrelate themeboth for a simple reason that can be explained by thiz example.....

cansider a case where u have a classes that need each other.....that is example1 object is there in example 2 and vice versa.....
observe.....

class example2
{
example1 ex1;
}b;

class example1
{
example2 ex2;
}a;

letz consider object b.....
note that "b" would contain "ex1" and "ex1" would contain "ex2"....and what is ex2???....logically it goes to infinity(since each instance contains the instance of the other in itself)!!!!!

so it doesnt make sense.....moreover u can only create an object if itz memberz are all defined!!!!!.....say in class example2, the example1 need to be understood by the compliler to allocate /putaside the value for that object,but to get theat done example1 class must be fully defined,u will find it dependz on example2 and hence not possible!!!!!

thiz iz the way i reason it out!!!!!!;)

Use SetBkMode() to make the background transparent. If you want to make the text partially transparent, you can't, not with the Windows API.

Using FindWindow in ISAPI

hello,

I tried using this function inside my ISAPI
HWND FindWindow( LPCTSTR lpClassName, LPCTSTR lpWindowName)
because i need to do some UI update under my ISAPI function. But the return handle is NULL.
I already tried this function in a dialog class and this works fine ...

Do you have any idea on FindWindow function limitation or is this ISAPI limitation?

I really need your help guys ...

Thanks,

jude

This is because ISAPI DLL is called from a service, which is executed on
non-interactive window station and therefore has no access to the user
desktop.

So is there anyway?

Can anyone help me ???
