I was wondering, is there a message or callback similar to WM_DEVICECHANGE that signals that the network is now connected?
I just tried a little application displaying all message I didn't process while connecting/disconnecting and didn't see any changes to my list of messages.
Is it possible to be informed that the computer is now connected to the network/internet with out doing a test every so often?
Cheers
Dave

It's not a message per se, but check out the ISensNetwork interface.

I need a method to find out All paths from a node( such as I) to another node (Such as J) in a digraph. the digraph is represented by adjacency matrix!
thanks!

you could do a google/yahoo search for boost::Graph or go to boost.org to find it - I'm sure it has algorithms for this sort of thing

Such an shortest-path algorithm was created by the late Professor Dijkstra.

Hi all,
Can anyone tell me how to access functions in an MDI application from a DLL?
|
|
|
|
|
Hi,
Same as othe DLLS. use header file..otherwise use GetProcAddress function.
There is nothing special for MDI for accessing DLL functions.

Hello,
I currently know 10 different programming languages. I have been working on a project for over a year in console C++ and just recently migrated the project over to C#. Just today I have migrated my project to VC++.net. While C# is very nice I have to admit that I feel much more at home in VC++.net. The code looks nearly identical to what I learned in a C++ structures course I took over a year ago.
Is there any standard advice you all can give me on what I should watch out for as I traverse through the MFC in VC++.net??
Thanks in advance.

Hi All,
I am currently a student and hopefully can get some help through this forum.
I have a project which needs me to create a monitoring software for a mechanical arm using Visual C++ 6.0. I need to capture the direction where the arm is moving and display the result in real time.
The requirement of the project is that i have to create a static lib and create a monitoring software that calls this lib. ( i dun understand but this is the requirement that was given to me )
But the problem is that i can't wait to receive and display the result at the same time.
I am a not an expert in Visual C programing so all suggestions and solutions are welcome.

In my program, I create a controlbar . If I double click on the controlbar, it can get the LButtonDblClk message. Then I create an rebar on that controlbar, but if I double click on the rebar, the controlbar can't get the LButtonDblClk message. And I find if I right click on the rebar, the controlbar still can get the right-click message. It is strange.How could I get the LButtonDblClk message in the controlbar when I doubld click on the rebar?
Thanks
Benben

are you sure it is the right control that is handling the message ? (be sure it is the child class tha is doing so)
TOXCCT >>> GEII power

|

Yes,I don't think it is a right control.
But what I mean is I want to do something when the user double click on the controlbar( include the area covered by the rebar), how should I do?(And I am sure the rebar needn't process this message).And it really work for right click message.
Thanks
Benben

I just want to complete a app in ms excel style , it seems multi doc/multi view, and one can give me an opinion?
thks a lot
|
|
|

Use MDI, multiple views per document too. You might want to take a good look at Chris' excellent grid control (I've used it in similar applications), as it should help with most of the 'spreadsheet' style stuff.

HI.
Steps to add a BMP as a resource.
and how to load it.
if Picture COntrol is used then steps
plz
thanx
|
|
|
|
|
Go to resources tab
right click on topmost tree item 'resources' / choose insert... / choose bitmap and click 'import ...', choose bitmap you want to import.
When you want to place it into some dialog then: Insert Picture Control (2nd icon from left), double click the control (you can see black rectangle on dialog) to see its properties.
Change type to bitmap; change image to your imported bitmap's name as displayed in 'Resources\Bitmap'
Thats it ... now the black rectangle should change to your bitmap.

i did all step u said .. but ther is only a white squre appear.
nothing else
|
|
|
|
|
Is there only a white square also when you run the program ? Because sometimes white square shows only in dialog design. Else then that you should try to change BMP's colour bit depth in some graphic editor, that should solve problem.
