I'm writing a App to scroll the window which is not foreground with the mouse wheel, And Use the Mouse hook In my code, first i reDirect the message like this:
POINT pt;
::GetCursorPos(&pt);
pMHSEX->MOUSEHOOKSTRUCT.hwnd=::WindowFromPoint(pt);
but this do not take effert so i change the code :
POINT pt;
::GetCursorPos(&pt);
pMHSEX->MOUSEHOOKSTRUCT.hwnd=::WindowFromPoint(pt);
::SendMessage(pMHSEX->MOUSEHOOKSTRUCT.hwnd,WM_MOUSEWHEEL,pMHSEX->mouseData,0);
return TRUE:
this works in many windows (foreground or not foreground with scrollbar inside) when the mouse move on it with the wheel scrolled, these window were all act,but when the mouse move to the IE window with Scrollbar then scroll the mouse wheel it does work 
I have searched some article, and some about the window whose class name is "Internet Explorer_Server", and i try to test:
#define ID_IE_ID_ADDFAV 2384
::SendMessage( pMHSEX->MOUSEHOOKSTRUCT.hwnd, WM_COMMAND,MAKEWPARAM(LOWORD(ID_IE_ID_ADDFAV),0x00), 0);
it appear a IE add favorite window, but how do i send a Scroll meesage to this window ?
Can someone help me? Thanks

I have to get the total count of the files present in a folder.I have to do a file transfer from that folder to another on a button click.Any help?Im using vc++
|
|
|
|

try FindFirstFile() and FindNextFile() or its MFC wrapper CFileFind to find the number of files in a folder
If you want to copy the entire contents of folder at once use SHFileOperation or if you want to copy one by one, use CopyFile().
|

Please check my code...
void CMydlgtestDlg::Oncount()
{
int count=0;
CFileFind f;
CString file="D:\\mframes";
if(f.FindFile(LPCTSTR(file)))
{
count++;
f.FindNextFile();
}
AfxMessageBox(count);
|

Like this..
int count=0;
CFileFind f;
CString file="D:\\mframes\\*.*";
BOOL bFound = f.FindFile(file);
while( bFound )
{
bFound = f.FindNextFile();
if( !f.IsDirectory())
{
count++;
}
}

i get a debug assertion failure when the code is run.it is written inside a member function of a button.
|
|
|
|
|
Press the Retry button while debugging and check the call stack to find the assertion location.
|
|
|
|
|
I gave an AfxMessageBox at the end ,it is there the error is displayed..it is just given to display the count;
|
|
|
|

You cannot put a int variable directly in a AfxMessageBox() function like in VB.If you want to show the count in message box, modify as follows
CString csCount;
csCount.Format( _T("%d"), count );
AfxMessageBox( csCount );

Thanks..it worked now...Now how to copy the files?
I have to copy all files from "D:\mframes" to "D:\new"
Have declared both as below.
mframes is declared as such to copy all files in it.
CString file="D:\\mframes\\*.*"; <br />
CString next="D:\\new";
|
|
|
|
|
CFileFind f;
CString file="D:\\mframes\\*.*";
CString next="D:\\new\\";
BOOL bFound = f.FindFile(file);
while( bFound )
{
bFound = f.FindNextFile();
if( !f.IsDirectory())
{
CString csFilePath = f.GetFilePath();
CString csNewPath = next + f.GetFileName();
CopyFile( csFilePath, csNewPath, TRUE );
}
}
|

Count is one more than the actual and the fioles are not copied to d:\new.rather they are just copied to d:\
|
|
|
|
|
ok. Debug and find the cause...
BTW did you notice the "\\" in the end of line CString next="D:\\new\\"; in the above post?
|
|
|
|
|
|
yea..now it gets copied to d:new.
Here i have already specified the folders.what if i want to check whether the directory i am going to create exists?
|
|

Gives an error "'PathFileExists' : undeclared identifier"

As has already been mentioned, use SHFileOperation().

I have created an MFC application in Visual Studio.
I have x and y values to be plotted for the graph which will display a curve.
I have no idea at all how to draw a graph in VS.
Is there any free tool, a fast and easy method I can incorporate into my application?
I just want to display a simple graph.

I want to send a string between 2 dialog. So I try to use SendMessage() with WM_COPYDATA message
Here is the code in send dialog
COPYDATASTRUCT cds;
....
::SendMessage(hWnd, WM_COPYDATA, (WPARAM) m_hWnd, (LPARAM) &cds );
And receive dialog code:
BEGIN_MESSAGE_MAP(RcvDlg, CDialog)
.....
ON_WM_COPYDATA()
END_MESSAGE_MAP()
BOOL RcvDlg::OnCopyData(){
...
}
It works, but while sending messeage, it locks the send dialog. So I want to change to another way, PostMessage. But I don't know how to implement. I tried to look on the internet, but cannot find what I want.
Can anyone help me? Thanks in advance,

Don't you see the following comments just below the help of WM_COPYDATA in MSDN[^]
An application must use the SendMessage function to send this message, not the PostMessage function.
|
|
|
|
|
oh, that's why I wasn't success.
thank you very much, Naveen.
So this means that when dialog A sends a string message to dialog B, it must be locked until receive the reply.
Is it correct??
