Could you have more details in relation to your answer or sample code, please??
Thanks in advance,

Using SetWindowsHookEx you should set global hook. Hook procedure should be placed in DLL.

Use WH_CALLWNDPROC hook type to intercept messages.

Thank you for your previous answer, but I need more information or sample code about "Hooks" taking into account my knowledge of Visual C++. I've seen the SetWindowsHookEx function but I don't understand how to use it.
Thanks in advance and best wishes,
LuisFer.

I took a look, I saw a nook, and on his head he had a hook. On his hook, he had a book, and on his book said how to cook. But a nook, can't read, so a nook can't cook, so what use to a nook is a hook cook book ?
Sorry, it's early Friday....

If you don't want to program, you can use the Spy++ tool with ships with VC++.
You can use it to detect all messages received by the window you can inspect.

can't get this code working.
DWORD fileLength = workFile.GetLength(); //line 1
char fileBuf[fileLength]; //line 2
workFile.Read(fileBuf, fileLength); //line 3
compiler says (all for line 2):
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2133: 'fileBuf' : unknown size

Hi !
Try this:
DWORD fileLength = workFile.GetLength(); //line 1
//char fileBuf[fileLength]; //line 2
char * fileBuf = new char[fileLength];
workFile.Read(fileBuf, fileLength); //line 3
....
delete[] fileBuf;
Best regards,

it says identifier undeclared.
|

workFile.Seek(pos, CFile::begin); //position pointer to beginning of file
workFile.ReadString(workString); //read the first line of text
thanz in advance!

The thing that jumps out at me is that you are opening the file with flags set for WRITE not READ.
I'll confess I did not thoroughly step through your code simply because I noticed that right away.
I hope that's it because that's easy.

I find that the majority of the problems I have are for just such "simple" oversights.
I'm glad it helped.

ON_WM_????
END_MESSAGE_MAP
what is the message used to tell a window to assert the OnRecieve method of a CAsyncSocket object.

G'day,
I'm using a CTreeCtrl with check boxes on each item in a dialog. During to call to the dialog's OnInitDialog() I set up the initial checked/unchecked status for each tree item, but these checks seem to disapear when the dialog is actually displayed.
I've poked around in my code and it seems that the checked status is actually lost for each tree item some time after OnInitDialog() returns.
I can check/uncheck tree items with the mouse after the dialog is displayed, but it just seems to lose the checks when initializing.
Can anybody point me in the right direction, please?
I'm sure this has been discussed here at CP before, but I can't find any references.
TIA,
Steve

Some code please - OnInitDialog handler would be best.

G'day Tomasz,
I won't post my actual code here (it's way too long), but the following snippet has the same effect. Note, I've set up the tree control in the dialog as having check boxes enabled.
BOOL CReportSettingsDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CString strItemName;
for(int i = 0; i < 20; i++){
strItemName.Format(_T("Item%d"), i);
HTREEITEM hItem = m_Tree.InsertItem(strItemName);
ASSERT(NULL != hItem);
m_Tree.SetCheck(hItem, TRUE);
}
return TRUE;
}
When the dialog above gets drawn, the tree displays the inserted items, but none of their check boxes are checked.
TIA,
Steve

The solution is quite funny. Here's what I found in the "Tree View Control Window Styles" at MSDN:
"TVS_CHECKBOXES:
...
If you want to use this style, you must set the TVS_CHECKBOXES style with SetWindowLong after you create the treeview control, and before you populate the tree. Otherwise, the checkboxes might appear unchecked, depending on timing issues."
To solve the problem, you have to:
(1) clear the 'check boxes' option in the tree control properties in dialog editor
(2) programatically set the style after the window is created and before items are inserted:
m_Tree.ModifyStyle(0, TVS_CHECKBOXES);
for (...)
{
m_Tree.InsertItem(...);
m_Tree.SetCheck(...);
}
(2) is not enough (at least on my W2K box) - you can't have your tree control created with TVS_CHECKBOXES style.

I have to continue to support an old MFC-based application that still uses ODBC to connect to an Access 97 database. (We're rewriting the whole thing as a web application but until it's done we have to continue to add features and support...) Anyway, the database is updated each time we release a new patch to the system (upgrade). The upgrades come down from the web, so we TRY to be kind on the size of the patch. Continuing to update an Access 97 is a major pain since pretty much everyone has moved on to 2000. However, if I convert the database to Office 2000, the database won't load through ODBC calls without installing at least MDAC 2.5. The patch is a single patch that supports Windows 95/98/ME/NT/2000 so (using InstallShield) the MDAC 2.5 object bloats the 4.5 MB patch to 13.5 MB (I suppose because of the cross-platform support).
Is there any minimal things I can do make this work without having to install the entire MDAC update?

Most IntelliSense problems can be fixed by closing the workspace and deleting the .NCB file. The NCB will be recreated when you open the workspace again.
