I probably shouldn't encourage this sort of low level hackery, it'll only hurt someone you work with one day...
However, why what you're up to won't work is due to the "this" pointer. All C++ member function calls have an implied first parameter which is the address of the object the function is invoked on. So if you write:
a->b( c );
the compiler converts this to:
<class of="" a="">::b( &a, c );
So in your case if you call:
p( &comobj, bstr );
it might all start working swimmingly.
Oh, and if it does don't tell anyone I told you or generations of coders will be cursing my name for spreading low level hacks around.
Cheers,

Great answer. Including all of the "It wasn't me who told you how to do this".

It works! That's so awesome!
I'm just asking to get the whole idea of that interface, COM and vtable stuff better.
Thanks a lot !

I was hoping that it was just to get an idea of what's going on under the covers, glad I could help.

hi i would to create a tools to make life easy.
i would like to join a few basic setup file on fresh installed pc's.
but i only wanna do a few click and not look @ the screen @ the each of each individual setup file.
i would program the order how to execute, open the setup file from known feeware /media software / ccleaner / etc, and programaticly click the button of the setup file.
there use to be a very known free anti spam / add program from the netherlands with did this.
it's easy to check the open processes for names.
but what to do next, if you have the handle of the setup file windows?
how do i make the very wel known 'next' button go click?
i have pretty wide knowlegde of visual c#, i have done some Nokia Qt c++, made a custom control draw control in like 2 days or so.
but not to much ms vc++, accept some mfc years ago.
the idea is, the app has to run on 1 minute old fresh windows installation.
so i would like to try it in c++.
how to scan all the processes running by 'username' in proceslist?
to get handle of the window, to find handle of the wanted button, checkboxes?
another posibility is to make the mouse move and click, since you know the the setup windows location.
set Focus, you probably can send a winproc message to the operation system and make it click.
read updates from progres bars, panel change.
could anyone help me solf this problem, ith any usefull info.
thank you
Bad = knowing 2 much

Hi,
Here m_ListInfoCtrl is a varible for CListCtrl
ie dialog listcontrol and a dialog variable
while( !m_pFrame->m_DbMgr.m_Rs.IsEof() )
{
m_pFrame->m_DbMgr.m_Rs.GetFieldValue( "LruIndex", nLruIndex );
strTemp.Format( "%d", nLruIndex );
m_pFrame->m_nLruIndex = nLruIndex;
m_ListInfoCtrl.InsertItem( nLruIndex-1, strTemp );
//---- LRU Name ------------
m_pFrame->m_DbMgr.m_Rs.GetFieldValue( "LruName",strLruName );
m_ListInfoCtrl.SetItemText( nLruIndex-1, 1, strLruName );
//----- MIl Bus ----------------
m_pFrame->m_DbMgr.m_Rs.GetFieldValue( "MilBus", strTemp );
strTemp.Insert( 0, " " );
m_ListInfoCtrl.SetItemText( nLruIndex-1, 3, strTemp );
m_pFrame->m_DbMgr.m_Rs.MoveNext();
}
}catch( CADOException& e )
{
strSql = "CSIRBaseView::UpdateListControl():GetFieldValue "+e.GetErrorMessage();
MessageBox( strSql );
}return FALSE;
Here firt two columns are coming ie LRUIndex and LRUName
but the third column MilBus is not displaying the value.
|
|
|
|
|
m_ListInfoCtrl.SetItemText( nLruIndex-1, 3, strTemp );
should be
m_ListInfoCtrl.SetItemText( nLruIndex-1, 2, strTemp );
I'm pretty sure.

Hi,
I have used
//---- LRU Type -----------
m_pFrame->m_DbMgr.m_Rs.GetFieldValue( "LruType", nLruType );
strTemp = m_pFrame->m_strLruType[nLruType-7001];
m_ListInfoCtrl.SetItemText( nLruIndex-1, 2, strTemp );
column 2 for LRU Type
I have used here 7 columns
all columns it is showing the values but for column 3 only
it is not showing the value.
Please help me.

/----- MIl Bus ----------------
m_pFrame->m_DbMgr.m_Rs.GetFieldValue( "MilBus", strTemp );
strTemp.Insert( 0, " " );
m_ListInfoCtrl.SetItemText( nLruIndex-1, 3, strTemp );
That is your original code. Notice that you're inserting a space into the string, and that's it. This is why nothing is showing in the column. All you're doing is inserting nothing... or more to the point, you're inserting nothing that can be seen by the naked eye.
Try putting an "A" or "Test" or something into that string, to double check that the code is working correctly. Because at this point, I think it is.

Scratch what I said before, I didn't look closer. I feel stupid.
Ok so honestly you probably don't even need the strTemp.Insert(...) call. If you take that out, see what happens. I'm betting that it'll work. The reason why I say this is because the " " is null-terminated. Though this shouldn't matter, I think that's what the problem is. I'm betting that if you take the Insert call out, then you'll be left with whatever value strTemp holds originally from the GetFieldValue(...) call.

He was having a problem with the column. Indexing for columns is the second argument for SetItemText.
When inserting an item, the item text defaults to column 0 (first column).
Setting item text is then indexed in the second argument, so the first function call to SetItemText is correct (index number 1). The second function call was incorrect, because there are only 3 columns, and there is no "column 3".
His problem was that he used index 3.

Possibly, but the bigger issue was the he was not using the return value from InsertItem(). If the list control has the either of the LVS_SORTxxx styles, then calling InsertItem(nLruIndex-1, ...) does not guarantee that the newly inserted item will be at position nLruIndex-1.

Good point. I think both points are valid then.

Hi,
I am adding one .lib dependency with my project using vs2008 and its conficting with MSVCR90.DLL.
Linker Error is: error LNK2005: __amsg_exit already defined in msvcrtd.lib(MSVCR90D.dll)
How can I resolved that?
|

|
|

What library or .lib ar you adding to the project?

Did you produce the library from source or was the .lib provided to you? My suspicion is that the .lib you are using has not been produced correctly.

Yes I build the source code using vc6 becuase I was not able to build it on vs2008.
Same lib is working on vc6 but not vs2008.
It is conflicting with msvcrtd.lib.
Please guide me to solve this issue....

|

|

Is the .lib project the same on vc6 as on vs2008?
Is the .lib project a static library or a dynamic library project?

Yes, it is same as on both.
And this is static library.

Your problem is that you're trying to link with two versions of the VC++ library. One's from VC++6 and the other's from VC++9.
The cleanest way of getting around this is to rebuild the VC++6 component using VC++9 - build it and clean up the errors and warnings. You can do some fiddling about with linker switches (/NOD and explicitly link your app with the libraries it wants) but there's a fair chance it'll fail somewhere in the build (if you're lucky) or produce all sorts of interesting errors (when run by your customer/professor).
Cheers,
Ash

Trying to link with a static library .lib file produced on vc6, using vs2008 is asking for a whole lot of grief. Mainly because of what Ash has replied to you with. You're best approach now is to try to get the static library to build on vs2008. What are the errors when you compile the library?
