Hi,
i've just managed to build a TABControl. Below this TabCtrl i have some Checkboxes which should be used to enable and disable all DialogItems from a Tab.
I.e. if i uncheck a checkbox, i want all elements from my first dialog, which is on my first tab to be disabled.
Is there any solution to dynamically get all elements from a dialog and not adding a member variable to each and disabling it?

GetWindow(...) with a loop
|
|
|
|
|
Should i put the ID's of all elements in an array and do the loop over the GetWindow or is there any other way?
|
|
|
|

No, have a look about the function.
code is:
CWnd*pw=GetWindow(GW_CHILD);
while(pw)
{
pw=GetWindow(GW_HWNDNEXT);
}
|
|
|
|
|
CWnd* pw = m_tab1.GetWindow(GW_CHILD);
while(pw)
{
MessageBox("trala");
pw=m_tab1.GetWindow(GW_HWNDNEXT);
}
ends in endless "trala"'s
"m_tab1" is the ctrl for my dialog.
in general i would write:
m_tab1.GetDlgItem(IDC_T1_OK)->EnableWindow(0);

Sorry, missed pw-> in code.
According to your code, the code is:
CWnd* pw = m_tab1.GetWindow(GW_CHILD);
while(pw)
{
MessageBox("trala");
pw=pw->GetWindow(GW_HWNDNEXT);
}
|
|
|
|
|

Now that i've gotten the handle to all items, i'd like to know how i may get information of which kind the item is.
is there any way to get to know whether the item is a button or a spin control or... whatever?

Yes: fix it.
i.e. vague question -> vague answer.

Wow, that was a very clear description of your problem 
There's nothing wrong with using XP as client and Vista as server, so I guess you'll need to investigate a bit more than that (e.g. use your debugger).

While asking a question please be specific as to what you are using , what exactly is failing , which framework are you working on, what language you are using , what is the error you are getting in log file and in which method or function it fails.These all things are mandatory if you want a proper answer to your question. Else, its all to vague

I hate coding but I luv to develop .

Sockets are not dependent on the operating systems (not even programming languages). You can have a C++ server and have a client written in VB (ugh...) connect to it.
So, you have essentially given no clue. All we know is that your program is "not working". So, the only possible suggestion to you would be "then fix it".
If you could give more details and be specific, one or the other would definitely answer your query. You might as well look at one of those plenty of articles on client/server programming. Search CP.

Why?

Why don't you use the mechanism COM provides for, i.e. QueryInterface?

thanks pallini for reply
Because I am getting the value from the IUnknown filter from the gmfbridge and now i want to connect the manually graph so that I have to use typecast this IUnknown filter to the IBaseFilter.

Your question is unclear, to say the least. I can't make head or tail out of it. Can you explain more clearly?

I am using gmfbridge to play the clips
hr = pController->CreateSourceGraph(wFilter, m_pGraph, &m_pSinkFilter);
where m_pSinkFilter is the IUnknown type. If I want to GetPin of this m_pSinkFilter then this function wants the IBaseFilter type.
GetPin((IBaseFilter*)&m_pSinkFilter, PINDIR_OUTPUT);
Is this possible

What happens when you try it?

The better thing is..
IBaseFilter *pFilter = 0;
HRESULT hr;
hr = m_pSinkFilter->QueryInterace(IID_IBaseFilter, (void**)&pFilter);
if(SUCCEEDED(hr))
{
}

That looks wrong, since m_pSinkFilter is already a pointer to an interface, you should write
GetPin((IBaseFilter*)m_pSinkFilter, PINDIR_OUTPUT)
(i.e. remove the address-of operator).
In any case, what is the purpose of bypassing the COM QueryInterface mechanism? Why don't you use m_pSinkFilter to QueryInterface for IBaseFilter?

Now I am doing this like as
hr = pController->CreateSourceGraph(wFilter, m_pGraph, &m_pSinkFilter);
hr = m_pSinkFilter->QueryInterface(IID_IBaseFilter, (void**)&FileSource);
if(SUCCEEDED(hr))
{
hr = ConnectFilters(m_pGraph,FileSource,mxfparser);
if(FAILED(hr))
{
MessageBoxA(NULL,"failed to connect","",NULL);
}
}
But Here now connectFilters Failed.

Hi,
I am an experienced programmer in Linux, but new to Windows.
I want to develop windows XP driver for a PCI based device.
Also, I want to write a device capability Demonstration application.
I am free to select Visual Studio 6.0 to Visual Studio 2008.
1. Is it a good decision to do the Demo Application development in VC++ Dot-Net, and Driver Development in Non-Dot net environment?
2.Which version of Visual studio is suitable for me, considering the future usefulness of the technical knowledge I am acquiring.
3.Please suggest some good books for Windows XP Driver Development.
Thank You very Much
Jacob
