makes use of CTabCtrl in a derived class.

The default CTabCtrl displays a white background (as expected) on my themed XP system. Perhaps the derived control you're using swaps in modeless dialogs when the user switches tabs? If so, the dialog's background will be COLOR_WINDOW (grey) by default.

Instead of the CTabCtrl derived control, you may want to try using a CPropertySheet (and CPropertyPages) and see if that gets you the desired behavior.

Hi Ravi, thanks for your answer.
I have been looking into CPropertySheet and the problem that I see, is that CPropertySheet behave like a Modal Dialog isn't?
And my CTabCtrl is inside a Dialog, like part of the controls of that Dialog.
Can I use the CPropertySheet like a normal MFC Control otherwise than a separated Modal Dialog?

Well, I'll try'it anyway Smile | :)

Thank you very much for your patience and assistance.

Extending Command Routing

Hi,
If I'm implementing a view that recieves WM_COMMAND messages, and OnUpdateCmdUIs, what is the easiest way to include some of my view's child windows in the routing, so that they can also recieve these notifications, without reflecting each notification one by one?

It's a bit hacky but I often override OnCmdMsg() and forward it on to the child windows to see if any of them want it.

Adding a new search function to the explorer

Hi
I'm writing an application and I would like to add a search function to it. What I would like to have is something similar to the "search file" function from the explorer, but using my own search search parameters and search engine. And this is where I get confused

Browsing the msdn I found two things :

-> Search Handler. I found a little description of what they are in the "Creating Search Handlers"(1) document, but that didn't help me much. What are they really capable of ? Are they the solution to my problem (custom search engine based on custom parameters) or are they just a tool to help XP search in file ? (I mean, like described here )

-> Explorer pane. I was able to implement a vertical explorer pane and adding a few event to it (straight win32 message loop, nothing fancy), but how can I display the search result the same way they are displayed when searching for file ? (To clear a bit this : I receive the "search" event. My app looks input values and perform the search. How can I present the results in the right pane (the listview) of the explorer ?)

Thanks !

Active document server in .NET instead of VC++

I have an MFC MDI application in VC++ which is active document server application which allows opening document in container like internet explorer.

Is it possible to create the active document server application using .NET framework and allow to open document in internet explorer?

Any tips on the same will be helpful.

Thanks.

I Believe, you are facing trouble using GetFileVersionInfoSize api, any way here is the link that simplify that process...

Why would there be trouble in using GetFileVersionInfoSize()? Aside from reading the EXE/DLL directly, that function, along with VerQueryValue(), are the only way to go.

below is sample code I m doing, I m getting Invalid data Error (13)

====================
DWORD dwVerInfoSize; // Size of version information block
DWORD dwVerHnd = 0; // An 'ignored' parameter, always '0'

TCHAR *szAppName= L"C:\\Documents and Settings\\Desktop\\unicows.exe";
TCHAR *verdata = L"";

//WIN32_FIND_DATA var;
//HANDLE hFileHandle = FindFirstFile (szAppName,&var);

dwVerInfoSize = GetFileVersionInfoSize( szAppName, &dwVerHnd );
cout << dwVerInfoSize; // here I m getting o/p as "2052"

GetFileVersionInfo(szAppName,0,dwVerInfoSize,verdata);

LPVOID lpInfo;
UINT unInfoLen;

VerQueryValue(verdata, _T("\\"), &lpInfo, &unInfoLen);

cout<< "lpInfo : " << lpInfo<<"\n\n"; //o/p is 0xccccccc
cout<< "unInfoLen :" << unInfoLen; // o/p is zero

cout<<"\n"<< GetLastError(); //13
========================

Here verdata does not point to a valid block of memory. See here for code snippets that use these functions.

Problem with CString

Hi All

I am making a dialog based application using MFC.
I have written a function which is as follows:

Function(CString strPath)
{
CString strTempPath;
strTempath = strPath;
}

Now when i debug this function then as soon as control passes line "strTempath = strPath;"

It causes UNHANDELED EXCEPTION ERROR.

Why it is happening?

Please reply.

Thanks

Could you show me your actual coding and what actual value coming in strPath..

Can you tell wots the exact error message. I feel your memory was already corrupted some time before it reached the Function(), but unfortunately its showing only from Function().
