Hi,
I'm running Visual C++ .Net 2003 with Service Pack 1, and .Net Framework 1.1, and I'm having issues with using GetComboBoxInfo and GetScrollBarInfo, even though they are available as functions when using the intellisense.
Although I've seen, tried and used a workaround to use the GetComboBoxInfo function, I was wondering if there is an update I need to install to avoid having to use the workarounds.
TIA
Tony

What issues did you come across?

OOps, I should have elaboarated on that.
Even though I have the option to use the functions, when trying to declare a COMBOBOXINFO or SCROLLBARINFO they come up as undeclared identifier, and GetScrollBarInfo is identifier not found.
As I said, I have used a workaround involving specifically declaring the struct and declaring links to USER32.dll etc.
What I really want to know is if there is an update that takes away the requirement to put so many workarounds in place to use this functionality?
TIA
Tony

Look at the function prototype in winuser.h. Do you have WINVER defined to be 0x0500 or greater?"One man's wage rise is another man's price increase." - Harold Wilson

Hi Guys,
Thanks for your help.
Looking in the project settings I see the WINVER was initially configured for 0x410.

Hi,
How can we identify the valid hardware MAC address from the list obtained by GetAdaptersInfo API?
For example, in my machine there is a real Network Adapter and a Microsoft Loopback Adapter. I need to get the MAC address of the real Network Adapter.
Thanks in advance! - ns ami -

Did I miss something??? 
If you mentioned about MIB_IF_TYPE_ETHERNET, it is coming same for both real hardware and microsoft loopback.
Could you please clarify? - ns ami -

| What about MIB_IF_TYPE_LOOPBACK ? txtspeak is the realm of 9 year old children, not developers. Christian Graus

|
|
|
| For both hardware adapter and Microsoft Loopback adapter, the type obtained is MIB_IF_TYPE_ETHERNET. Not MIB_IF_TYPE_LOOPBACK for Microsoft Loopback adapter. So I cannot distinguish which is the hardware adapter. - ns ami -

Something in my app. (C/Win32)is setting SetLastError and I want to debug it, eg capture all calls in my process to this function.
Any idea how I'd configure VS to break here?
Thanks

This is how I do this -
Start Windbg.exe.
Open your executable.
Set the break point - bp kernel32!SetLastError
When it breaks issue any of the stack backtrace commands - k, kp, kP etc.
|
|
|
|
|
Just call SetLastError(0); by starting of you process.
Set a breakpoint there and then - by stopping -
take the "Go to Disassembly" from the context menu...
Now - step by F10 to "call", then - F11 to "jmp", then - F11 to "mov".
Set your second breakpoint here to keep all calls of SetLastError(..)
and press F5 to get it

Thanks for the responses. I managed to find a breakpoint for some function that releases memory. Need to brush up on my assembly perhaps? 
Not quite what I asked, however a chap at work suggested typing $err into the watch window, this dispays the current value of GetLastError so I can step through code seeing where it changes.

I am confused by reading many articles.
Can any one tell me how many message queues are there in dialog based application.
Are there separate message queues for each window or each thread has its own message queue.

A dialog based application has one message queue.
A thread has its own message queue, if it's an UI thread. As a result, a window can have more than one message queue, if it has multiple UI threads running within.

Hi Rajesh,
Hope you're good and having fun! 
I got a little confused when I read your post....
Rajesh R Subramanian wrote: As a result, a window can have more than one message queue, if it has multiple UI threads running within.
Ummm...
Not really sure what you mean here, but to my knowledge a window is only served by one message queue and pump in the sense that messages sent to the window will be queued in the message queue that belongs to the thread that created the window in the first place.
On the other hand, you may of course spawn new UI-threads from your "window" and create new windows in the newly created thread.
Or, do you really mean that messages sent to a window may end up in different threads/queues?

Hi Roger,
Yep, I'm good. Thanks. How's it going for you?

I said a Window (the program) can have more than one Message Queue running, simply by creating UI threads within. These message queues need not necessarily have anything to do with the message queue of the application window itself (to which all the messages are posted from the outside world). When I need a queued event dispatching mechanism, I can create UI threads.
Roger Stoltz wrote: On the other hand, you may of course spawn new UI-threads from your "window" and create new windows in the newly created thread.
I think that the term "UI thread" is horribly misleading, as a UI thread need not have a UI associated with it at all! I can have UI threads running around without associating any of those to a window.
Roger Stoltz wrote: Or, do you really mean that messages sent to a window may end up in different threads/queues?
I can of course re-route the messages internally if I have additional UI threads running within.
Example: A server program that I wrote, when it receives requests to compress rendered output videos, it just routes the message to a slave (an "ui" thread) and returns. The slave would automatically process the requests in a FIFO basis. The compression need not be done urgently, so I avoid additional threads, and at the same time, eventually every request will be processed sooner or later.
I'm not sure I got your queries right; let me know if I've been unclear somewhere.
