add few message handlers in some suspected windows (i.e. main-frame) to see where the message is sent.
it must be somewhere, then transfer it from the window to required place.

i.e. the button ID is ID_TEST, add a menu item as ID_TEST.

in main-frame, wait for the message (messge=WM_COMMAND, wParam=ID_TEST).
"wait" means u put a messagebox there then click the menu to see if the message is processed to the window.

How to slow down process in Windows

I have an unusual task: slow down process in Windows(I have only executable(s) of this process.
If there's no way to slow down stand-alone process, I could slow down oll system. What is the better way to do it? Is it effective to make infinite loop process with real time priority. Confused | :confused:

If you're running W2K, just use the task manager to reduce the process's priority.

how to change field order in *.mdb

I created a database using CDaoDatabase and the fields were originally
arranged using m_nOrdinalPosition parameter in CDaoFieldInfo.
Now, I want to change a order whenever I want.
Is it possible?

How about the records?
Is it also possible to change the order of records?

Not that I know of.

Again, not that I know of. Most of the time, you'd specify a sort order in your SQL query to access the recordset in a specific order.

Ask in the SQL/ADO/ADO.NET forum. They will probably be able to give you a more definite answer.

Hooking other applications?

User 66587-Jun-03 8:20

Hi
I'm trying to hook the message procs of other applications, this is the code I currently use, and which fails:

HWND wndMIRC = ::FindWindow("mIRC", NULL);
m_hMenuHook = SetWindowsHookEx(WH_CALLWNDPROC, HookCallWndProc, 0, GetWindowThreadProcessId(wndMIRC,0));

SetWindowsHookEx() returns NULL if the first parameter applied to GetWindowThreadProcessID is different from the HWND of my own application Frown | :(

Why does this not work? Do I need to place my hook procedure into a DLL or what's wrong. I can hook my own application, but this is quite senseless and not what I want to do.

regards

FontSize

I was working in MS VisC++ Intro edition when my monitor went dead. Not having a spare around I decided to use a PC to TV device. I am using it on a 13". My problem is that when you use the system's, "Appearance",(Win98)tab to alter the look of the desktop, it increases all aspects of font size in an API but the window text. Can I insert some code in the root directory of IDE to supplement font size changes? If so, how?

Do you mean to say you want the code in your editor to look bigger? If yes, go to Tools-> Options-> Format and set the font size. If no, sorry, I haven't really understood your question.

Resize CToolbar

Konrad Windszus7-Jun-03 3:24

Konrad Windszus

7-Jun-03 3:24

I use a toolbar within an dialog. This toolbar is resized, whenever the dialog is resized via a call to SetSizes (the height and the width are changed). But sometimes if the dialog windows was inactive for some time, the toolbar gets the wrong size. Looking into the code of CToolBar::SetSizes I found the following:

<br />
if (::IsWindow(m_hWnd))<br />
{<br />
// set the sizes via TB_SETBITMAPSIZE and TB_SETBUTTONSIZE<br />
VERIFY(SendMessage(TB_SETBITMAPSIZE, 0, MAKELONG(sizeImage.cx,<br />
sizeImage.cy)));<br />
VERIFY(SendMessage(TB_SETBUTTONSIZE, 0, MAKELONG(sizeButton.cx,<br />
sizeButton.cy)));<br />
Invalidate(); // just to be nice if called when toolbar is visible<br />
}<br />
else<br />
{<br />
// just set our internal values for later<br />
m_sizeButton = sizeButton;<br />
m_sizeImage = sizeImage;<br />
}

I think the problem is that the toolbar is only resized, but the new size isn't stored in the local variables m_sizeButton and m_sizeImage. I can't access them because they are private. It seems that sometimes, the Toolbar is completely redrawn with the sizes stored in m_sizeButton and m_sizeImage. I think this is a bug in CToolbar. It should always set the local variables to the current sizes (no matter if the window exists already or not). How can I get around this bug.
In which method the Toolbar is redrawn with the sizes from m_sizeButton/Image? When is this method called? And the most important question, how can get around this?
I use Visual Studio 2003 with the MFC 7.1. Thanks in advance, Konrad Windszus

CListCtrl bug

Konrad Windszus7-Jun-03 3:19

7-Jun-03 3:19

I have got a CListCtrl (Report View) in a resizable CDialog. Whenever I resize this dialog, I change the column width via a call to CListCtrl::SetColumnWidth, so that the horizontal scrollbar isn't necessary.
Unfortunately there seem to be a bug in the CListCtrl. Whenever a vertical! scrollbar is showed (because there are more items in the CListCtrl than it can display) and I scroll down and then resize the CListCtrl that the vertical scrollbar disappears, the first row in CListCtrl is empty and not selectable. Seems that the scrolling doesn't work correctly in this specific case.
I use the following code in OnSize of the CListCtrl:

<br />
CRect rect;<br />
GetClientRect(rect);<br />
	<br />
SetColumnWidth( 0, rect.right - nLengthWidth );<br />
SetColumnWidth( 1, LVSCW_AUTOSIZE_USEHEADER );<br />
<br />
CListCtrl::OnSize(nType, cx, cy);<br />

Even I can reproduce the bug and found also some postings in the newsgroups from developers which had the same problem, I don't know how to solve the problem.

Please help me. I had the problem with MFC 4, 7, and now even with 7.1

Thanks in advance

Statusbar text for toolbar

Konrad Windszus7-Jun-03 3:11

7-Jun-03 3:11

I have got a Toolbar in a CDialog. This dialog is a child of CFormView. The tooltips for the toolbar are working, but I would like to display the appropriate text in the CMainFrame's statusbar, too.
So far only the text for the Toolbar ID is shown in the statusbar, when I place the mouse cursor over it. But I would like to have the text regarding to the single buttons of the toolbar.
Any hints in which method the statusbar text messages are handled and how i can display the correct text in the statusbar?

Thanks in advance
Konrad
