I want to prevent a window from being minimized(currently it minimizes itself as soon as it is no longer the foreground window), I think I need to write a hook, but I don't know what message I need to capture... can some one please give some detailed solution? Thanks a lot.
|

What about to create that window without minimize button ? 
And remove minimize command from it's system menu ?

The target window was not created by me, it's a third party progrram, I just hate it when it keeps minimizing itself so...

I'm handling WM_CONTEXTMENU message in dialog, invoked by keyboard. It contains two List controls. How to find which one (if any) is activated ?
I tried to get HWND of active window by ::GetActiveWindow()
and comnpare it to HWNDs of list controls get by ::GetDlgItem().
But they are never equal, even if some of the List controls is focused.
Any idea how to do this ?
Thanks

Have you tried GetFocus()?

Yes, the same result. But I've solved that,
i'm handling listctrls' NM_SETFOCUS and NM_KILLFOCUS and i remember which was focused last
But another mystery for me is, why NM_RETURN from list control is never sent 
I look at messages in Spy++, it's always only finding default dialog item and invoking that.

MFC has a function named AfxDumpStack() or something like that. There are several articles here on CP for crash handling and dumping the stack. Also see John Robbins's BugSlayer articles on MSDN.

Hi,
Thanks for the reply.
This is no good to me for 2 reasons.
1.
I am not using MFC
2.
If i where then i dont want to output it, i need to actaully do something with the stack frames.
I have managed it now by using __asm blocks and using the esp pointer.
Not sure i you can help with this question.
Do you know how to get the module name or HMODULE that is mapped for a particualt section of memory. e.g.
A module is loaded at address 0x01000000. There is a function in that module at address 0x01000123. How can I determine which module that 0x01000123 is inside
Many Thanks
Ceri

I had to use an application that use a National Instrument Data Acquisition card (a PCI card). When using the application the blue screen appears. The informations in the blue screen are
..................
IRQ_LESS_OR EQUAL (or something like this....)
............ NiDAQ32.??? (I don't remeber exatly)
....
I have to investigate about this problem. Here are some questions:
1) Can I say that the problem is not in the application but in driver/driver configuration?
2) What can I do with the blue screen information?
3) Can I call the National Instrument staff and send them the clue screen information / the Windows dump file?
4) What can I do by myself?
Thank you.

If your are using Windows NT/2000/XP then problem is probably the driver. Most likely an access violation in the driver caused the system to crash. In Windows 2000/XP you can find a dumpfile in the c:\winnt\minidump directory.
There are 2 reasons that the driver might have crashed:
1. You passed some invalid pointer or whatever that caused an access violation in the driver.
2. The driver is bad. I have worked will some of the NI drivers/dll's in the past and this would not surprise me.

Thanks.
How can I explore the dump file (I mean which tools I have to use)? Can I symply find there the parameters I passed to the driver?
Thank You.

You can download the "Debugging Tools for Windows" package from the MS site. IN this package there are some tools (like dbgwin) to view the dump files.
But I personally haven't been able to get any meaningfull info from the dump files.

Hi,
You can use google.com to make a search with the information that you have onto your blue screen. Most of the time, you will find a web page that explain approximatively where the problem is.

Everything's beautiful if you look at it long enough...

Hi All,
Hi How can Achieve the below proposed..
I need to highlight a check button (MFC CButton) when the control gains focus (by keyboard navigation)... The highlight should be similar to the highlight effect of MouseOver.....
Any Help would be appreciated..
Thanks.
Henrik

Which MouseOver effect do you mean? What should happen if the button gets the focus?
|
|

Hi,
In a Hello World MFC Application create a CheckBox Button (with no caption and no caption space) on the main dialog form...
When i move the mouse over the control here it gets an orange (inner) highlight - so you can see that the button is in focus..
This does not happen when you tab into the control by keyboard...
run the application and watch how the checkbox looks different when you move the mouse over it - then try to tab into the checkbox - and you can see that no change occurs...
I owuld like the same effect to be applied to the control when the user tabs into the control as if the user moved the mouse over the controll..
I'm sorry I cant be more specific... I'm kindof a newbie with Visual Studio / MFC...
/Henrik

|
|
|
|
Um, Seems to be an XP feature - Saw my code on win2k today - and there there is no mouseover effect.......
Well ... then my problem is not really important anymore as the solution would only work for Xp users......

Which is better to use
AfxMessageBox
or
CWnd::MessageBox ?
According to the SDK Documentation:
"Use the global function AfxMessageBox instead of this member function to implement a message box in your application.", but with CWnd::MessageBox one can set the caption of the message box.
Anybody got any ideas or comments.

That is probably the point. AfxMessageBox sets the name of the application in the title, so you can see where the message box is comming from.

Depends on what you need to display. You can always call ::MessageBox() for complete control, or use the MFC class members to hide away the details of hwnds, etc. as the situation requires.
