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.

thanks to both of U dear but I m not able to get desired o/p Confused | :confused:

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
========================

tell me what's wrong in it...

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().

Afx Message Handling in CStatic as Child-Window

_NielsB15-Sep-05 2:19

15-Sep-05 2:19

Hi!

I have a question about afx-message-handling in a MFC-Dialog (VS.NET 2003, WinXP).
I've got a main Dialog (CDialog) and a Child-Window in it (CStatic).

The goal is to handle afx-messages from the CStatic (ie. ON_WM_LBUTTONDOWN()) .
I did use the standard afx-message-map-mothod (ie. mapping ON_WM_LBUTTONDOWN() to afx_msg void OnLButtonDown(UINT nFlags, CPoint point)), but nothing happens.
Only the messages and handlers of the Main-Dialog are working.

I tried to put the focus on the Child-Window manually - no sucess. I tried to use CWnd instead of CStatic - no sucess.

Perhaps the CDialog messages are blocking the messages of the CStatic?!
Im really new in this and need a hint.

thanks in advance!

Include this style: SS_NOTIFY with the CStatic.
m_Static.ModifyStyle(0,SS_NOTIFY);

this is this.
