If your message ID is a constant, use ON_MESSAGE. If you get the ID by calling RegisterWindowMessage(), then use ON_REGISTERED_MESSAGE.

Hello all,
Could you please help me with this situation?
In the middle of my program, I create a FULL SCREEN TRANSPARENT HIDDEN WINDOW which is TOPMOST. When I click on my left mouse button, I want to retrieve the handle to the window under cursor(next z-order) underneath this transparent hidden window.
I am doing it like this when handling WM_MOUSEMOVE message, it is causing too much flickering.
// A full screen transparent window shows up
// Temporarily ShowWindow(hwnd, SW_HIDE) the full screen transparent window
// GetCursorPos() and do a WindowFromPoint() to get the window under cursor
// ShowWindow(hwnd, SW_SHOW) full screen transparent window
Could you show me how to use WindowFromPoint(), ChildWindowFromPoint(), and ChildWindowFromPointEx() to achieve this without hiding and showing the full-screen transparent window? Or is there any other way to do this? Thank you very much in advance.

Is it impossible to save and read struct to file if it contain the type CString so:
---------------------------
typedef struct p{
CString name;
int age;
}p
--------------------
p* s = new p;
...
...
file.Write(s, sizeof(p));
|
|
|
|
|
A CString doesn't contain the actual contents of the string, but a pointer to it. So you can't just write a binary copy of the struct to a file. Either use the MFC serialization mechanism or define your own I/O routines for the struct that save and restore the text in the string.

how can i display the progress of the CFptConnection::GetFile() method using the CProgressBar?
thanks
|
|
|

You wont be able to do it with the CFptConnection::GetFile() method, you'll have to use a combination of CFptConnection::OpenFile() and CInternetFile::Read(). Then all you need to do is a simple calculation based on the file size and the amount that you have downloaded.

I'm having a hard time trying to create a new dialog box and getting it to open whenever the program opens in a Dialog Based application in MFC. Can ANYONE help?
I Want Chicken, I Want Liver, Meow Mix, Meow Mix, Please Deliver...

If you want to show a dialog when the program opens you can declare the dialog instance and the DoModal. Note: This is not the way to create a splash screen.
Ex:
CMyDialog dlg;
dlg.DoModal();
You should include the above code on the PreCreateWindow or similar.
Hope it helped!

Hello,
UC I have made a program to retrieve data from the database for some person.
Now,everytime he formats the disk or takes the program along with the database to another system,he should install the database using ODBC...present in control panel.
How to automate this installation task from the program?
That person is extremely new to computers and can just work on it and nothing else.
Please help me fast.
Thanx:

I haven't done this but the ODBC info is apparently in the registry: On this W2000 machine under HKEY_CURRENT_USER\Software\ODBC\ODBC.INI. Try exporting the appropriate entry as a .reg file.

There is no Class Wizard in VS.NET. However you can make command and message handlers through property window.

Alright, i wrote a small program to download a file using a CInternetSession and a CInternetFile.
1) How do i retrieve the total FileSize of the file that should be downloaded?
2) The File is Truncated at random positions (?), when writing the buffer (file->ReadString(line)) to a file with fputs(outfile,line). How can i fix this ?
any help would be greatly appreciated !

Are you trying to download binary files or text files?

i want to download binary files using http

You initally stated using CInternetFile which is the base class for CHttpFIle and CGopherFile (spelling?).
I use this call to find the length of the returned data for CHttpFile calls. I do not know if it works with CInternetFile.
pHttpFile->QueryInfo(HTTP_QUERY_CONTENT_LENGTH, strRetBufLen);
The call pHttpFile->GetLength() returns the length of the sent string.
Hope this helps.

Hi.
The solution is very simple:
SELECT * FROM Table WHERE Name Like 'Ali*'
The question is, how to implement this:
1) If you're using Recordset-classes derieved by the classwizard, you
have to modify the CDaoRecordset::m_strFilter member
(like CMySet::m_strFilter = "Name like 'Ali*'). Remember that there is no
'WHERE'.
2) If you're using recordsets returned upon an querydef, just open the
querydef with the whole SQL-string, including that 'like' condition.
If you have further questions, you can contact me by eMail, as I'm often in touch with DAO and SQL in my projects.

How can i add a tooltip to a buttons and to ToolBar burrtons?
thanks
|
|
|
|
|
Hi,
- to add a tooltip to a button control use CToolTipCtrl::AddTool (...)
- to add a tooltip to a ToolBar I use the Ressource Editor to add menu-items. The ids of my menu items are associated with my toolbar buttons (they have the same ressource id). In the properties dialog of a menu item, put any text in the "statusbar-text" field. The part of the string after a '\n' is used as tooltip for the toolbar automatically by the framework.
Nice day ,
