Hello Friends
I m creating a one dlu where I m trying to get handle of child window(ListBox of Dialog) that is defined in another dlu.
First I Get handle to main Dialog by using FindWindow as:
HWND GR=FindWindow(NULL,"Edit Group"); //Edit group is Dialog name
I m having one groupList having Id IDC_GROUPLIST.
Now I want to get Its handle.
I tried FindWindowEx as
FindWindowEx(GR,NULL,MAKEINTATOM(0x800),"ListBox");
But I m not getting the result .I m not sure abt last parameter.
M i doing right or suggest me some other solution to get cild Window handle?
Thanks & Regards

You could try FindWindowEx(GR, NULL, "LISTBOX", NULL); instead.

Thanks,It is working.But can u suggest me for spinner b'coz I m having too many spinner in my Dialog but I need the handle for a specific spinner.

All controls have an ID that is defined by the resource editor.
You can use GetDlgCtrlId[^] on the control handle to check if it is the handle of the control that you're expecting.

I need that handle in different dll where i dont have Id.
If I have that Id then I can use GetDlgItem.(In that case there was no prob).
but I m not having in this dll.

I still think it will work. You should try it.
I can think of another way of doing this.
Create a hidden control with a caption just after the control that you're targeting.
By after I mean in terms of Z-Order.
Then after you get the handle to your control, you can use GetNextWindow[^] and GetWindowText[^] to check if it is the control that you're targeting.

I tried with this but it is always returning only the text of One Id.
I saw that "GetWindowText cannot retrieve the text of a control in another application." in MSDN.
What I do now?

Why do you need to "find" something that's already there? (stored in CListBox::m_hWnd)

I m not using MFC Sir ji.

If you don't use MFC, the idea is still the same.
You could store the handle of that control into a member variable when you create it, and use that member variable to manipulate it, or have it sent to another window that needs it. Simpler than using APIs to "find" the control and fetch its handle?

Hi,
This question has been posted to other forums without success (so far).
I am not a C++ coder. I usually work with VB and occasionally C#.
I have some old cde that has a problem, and can't get a 'simple' string conversion working.
This is a COM DLL used by VB6.
The function is defined as follows:
STDMETHODIMP CParser::GetAttributeValue(BSTR strName, VARIANT strPath, BSTR *pStrVal)
The problem is that strPath is incorrect, and I need to know what it is.
Currently I have the following:
return Error("Error in GetAttributeValue. The node Path specified was not found.");
This works, but I want it to give me the path.
This does not work:
return Error("Error in GetAttributeValue. The node Path specified (" + strPath + ") was not found.");
The error is:
error C2679: binary '+' : no operator defined which takes a right-hand operand of type 'struct tagVARIANT' (or there is no acceptable conversion)
I understand it is a type conversion problem, but can't seem to get the syntax correct.
Trying something as simple as this does not work:
return Error("Error in GetAttributeValue. The node Path specified (" + _bstr_t(strPath) + ") was not found.");
error C2668: 'Error' : ambiguous call to overloaded function
Trying this also does not work:
return Error("Error in GetAttributeValue. The node Path specified (" + _bstr_t(strPath.bstrVal) + ") was not found.");
error C2668: 'Error' : ambiguous call to overloaded function
Other failures:
return Error("Error in GetAttributeValue. The node Path specified (" + BSTR(strPath.bstrVal) + ") was not found.");
error C2110: cannot add two pointers
Please help. I don't know what I have to do to fix this.
Error() is defined in COMDEF.h:
static HRESULT WINAPI Error(LPCSTR lpszDesc,
const IID& iid = GUID_NULL, HRESULT hRes = 0)
{
return AtlReportError(GetObjectCLSID(), lpszDesc, iid, hRes);
}
Apparently CstringT can be used as it allows conversion between VARIANT and other TYPEs. But how do I use it? This is Visual Studio 6. CStringT isn't included with this old compiler.

I believe this post is in the wrong section. It should be in ATL.
Sorry. Mods, feel free to delete.

If anyone wants to know, I fixed it by doing the following:
return Error(LPCSTR("Error in GetAttributeValue. The node path specified (" + _bstr_t(strPath.bstrVal) + ") was not found."));

Hi
I am currently working on a new project that allows users to chat to their friends, build houses, explore, and creating characters and also to upload multimedia into the 3D world so their friends can see and listen to the media at the same time.
I need someone to please help me with it, and if you are interested could you contact me here.
Thank you.

Nobody is going to write the whole code for you. You should start yourself and if you'll have problems, then ask here.

This question has been asked a number of times already.
Please read How to get an answer to your question specifically the part about not expecting other people to do the work for you. Having read your biography from the link on your home page I suspect you may not have sufficient experience to consider embarking on such an ambitious project.

Hello,
I'm writing/maintaining an MFC app that makes extensive use of a database API that uses std::min and std::max, which is used in most of the application's translation units. Therefore, it makes sense to include the APIs convenience header (which in turn includes everything) in stdafx.h. The API requires that I #define NOMINMAX, so that the C++ std library's min and max function templates are used, rather than MS's legacy min and max macros. I have #define'd NOMINMAX in stdaxf.h . This worked fine for a long time. However, I recently installed the MFC 2008 feature pack. I must now #include afxcontrolbars.h. However, this header has inline functions that are dependent on the min and max macros which are now missing. I tried to "#include algorithm; using std::min; using std::max;" immediately before I include afxcontrolbars.h, so that std::min and std::max would be used as drop in replacements for the macros (this has worked in other areas in the past) but stdafx.cpp still doesn't build:

Can you do something like this:
#undef NOMINMAX
#include "afxcontrolbars.h"
#define NOMINMAX
|
|
|
|

Richard,
Thanks for that. I should have mentioned that that was the first thing that I tried. The result was exactly the same compiler errors as when I don't #undef:
1>------ Build started: Project: Lustre, Configuration: Debug Win32 ------
1>Compiling...
1>stdafx.cpp

1>c:\program files\microsoft sdks\windows\v6.1\include\gdiplustypes.h(497) : error C3861: 'min': identifier not found
I guess that exactly the same error message appears because stdafx.h is included in some header that is included somewhere, directly or indirectly, in gdiplustypes.h et al, which are included in afxcontrolbars.h.

Sternocera
