Ok, after mucking around with this a little more, seems this is *one* way of getting the job done.
I am calling this code once a button is pressed to bring up an application to the foreground.
1) CWnd::FindWindow() finds the window based on the file name.
2) CWnd::SetWindowPos() shows the found window as on top, without resizing it or moving it.
3) CWnd::ShowWindow() is making sure the application is not minimized/maximized.
BOOL rc;
CWnd* my_wnd = FindWindow(NULL, "Application-Name");
if (my_wnd != NULL)
{
rc = my_wnd->SetWindowPos(&wndTop, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE|SWP_SHOWWINDOW);
rc = my_wnd->ShowWindow(SW_SHOWNORMAL);
}
What I'd like to know is another way of getting the CWnd pointer to the window - I don't like writing code that depends on another applications having the same title (it very-well could change without me knowing, either by the dept. that wrote the code changing it and forgetting to notify me, or someone's changing the title of it for some purpose of their own).
So, now my search moves onto looking for another way of finding a specific window that is running since FindWindow() relies on the window title not changing.

SetForegroundWindow. with some caveats.
Here's a great article :
http://www.etree.com/tech/Articles/attachthreadinput.pdf
And here's some code to do it:
DWORD MyThreadId=GetCurrentThreadId();
DWORD ForeThreadId=::GetWindowThreadProcessId(::GetForegroundWindow(),0);
HWND hForegroundMe=0;
// Get handle to the window you want to place in the foreground.
// For instance use EnumThreadWindows if you know the ThreadId
// (perhaps you have it saved in a shared memory?)
// or use EnumWindows if you know the window text of the window
// you are looking for...
if (GetWindowLong(hForegroundMe,GWL_STYLE)&WS_MINIMIZE)
::ShowWindow(hForegroundMe,SW_RESTORE),::UpdateWindow(hForegroundMe);
if (ForeThreadId!=MyThreadId)
AttachThreadInput(ForeThreadId,MyThreadId,TRUE);
::SetForegroundWindow(hForegroundMe);
if (ForeThreadId!=MyThreadId)
AttachThreadInput(ForeThreadId,MyThreadId,FALSE);

I'm experimenting with hooks, trying to prevent a BN_CLICKED message from reaching it's target window (a 3rd-party app).
I've successfully hooked the event using a WH_CALLWNDPROC hook. Unfortunately this type of hook doesn't allow the message to be altered.
All my attempts hooking BN_CLICKED using other hooks like WH_GETMESSAGE, WH_MSGFILTER and WH_SYSMSGFILTER have failed. These hooks receive lots of other messages, but not BN_CLICKED. Making the hooks system-wide didn't help either.
Can someone tell me if what I'm trying to do is even possible?
Thanks...

It is possible - I've done it in several applications. I have successfully used two different methods. 1) Global message hooks and 2) Remote Thread Injection. #1 works if you need to search for the target process(es) and #2 is good if you know the process already. For both cases, I use GWL_WNDPROC to replace the WndProc with my own. Then you get every message and can supress the ones you don't want the main WndProc to get.
If you need some more help, let me know. I found most of the examples of how to do both #1 & #2 somewhere around CodeProject.

Thanks a lot, I'll check out the GWL_WNDPROC and get back to you if I need further assistance.
I'm delighted to hear that my efforts trying to do this were not in vain!

Anyone knows how to deal with ghost windows in XP? How to get rid of the ghost windows in windows XP system with Platform SDK? Thanks.

I think you'd better call Ghost Busters.
Sorry, I couldn't resist.
Honestly though, I have no idea what you are talking about.

Windows XP: If a top-level window stops responding to messages for more than several seconds, the system considers the window to be hung and replaces it with a ghost window that has the same Z order, location, size, and visual attributes. This allows the user to move it, resize it, or even close the application. However, these are the only actions available because the application is actually hung. When in the debugger mode, the system does not generate a ghost window.

How do I write a regular expression for ISO8601 date and time with timezone? More specifically, how do I detect the presence of the timezone bit using regular expressions.
I'm allowing a very limited set of the possible formats for ISO8601 to make it easier.
eg.s "2002-03-22T14:26:39Z", "2002-03-22T14:26:39+01:00", "2002-03-22T14:26:39-01:00"
I get stuck when looking for the '-' sign and I don't seem to be using the escape sequence properly. I'm working from our own http://www.codeproject.com/cpp/rexsearch.asp, but clearly don't understand them properly.
Thanks in advance.

Alice thought that running very fast for a long time would get you to somewhere else. " A very slow kind of country!" said the queen. "Now, here , you see, it takes all the running you can do, to keep in the same place".

I'm using CHtmlView - derived class CHtmlCtrl (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnmsj00/html/cpp0100.asp) for use in dialog boxes. I need to navigate that control to some page (for example about:blank) in dialog's OnInitDialog(). But Navigate() is not blocking function, how to block until CHtmlView::OnDocumentComplete() is signaled ?

I have set the rich-edit control of a CRichEditView to read only
(GetRichEditCtrl().SetOptions(ECOOP_SET, ECO_READONLY); )
which works fine, except that the scrollbar is then also "readonly" - the user is unable to scroll the text in the window! Is there a solution? (Yes, I've tried EnableScrollBar.) TIA.

Here is my solution :
1. open both databases, select * into source recordset, create recoprdset in destination database
2. select all rows from source database into source recordset
3. destination recordset.AddNew()
4. copy all field values from source recordset to destination recordset
5. update destination recordset
6. go to 2

It means that i must use CRecordset or i can use and CDaoRecordset?
|
|
|
|
|
It depends what database acces are you using.
CDaoRecordset is dor DAO, CRecordset is for ODBC.
It is recommended to use ADO or ODBC, i'm using this wrapper class for ADO : http://www.codeproject.com/database/caaadoclass1.asp
CADODatabase + CADORecordset

my function for easy copying of recordsets is here :
void CSynchronizeDlg::CopyRecordset(CADORecordset &dst, CADORecordset &src)
{
CString tmp;
for (int i=0; i<src.GetFieldCount(); i++)
{
if (src.IsFieldNull(i))
{
tmp.Empty();
dst.SetFieldValue(i,tmp);
}
else
{
src.GetFieldValue(i,tmp);
dst.SetFieldValue(i,tmp);
}
}
}

Does CWinApp::Run() gets called automaticaly when starting the app, or do you have to do this yourself?
I've deprectated the Run-function, just added a messagebox in there and a call to the parent-Run. But the messagebox never appears, so I guess Run() isn't called automaticaly. (or am I wrong?)
And how do I have to call Run()? Just calling Run(), or is there a Start() function like in java? And from where? From Initinstance()?
