if ur going to declare a variable in the header file and if that header is included from more than one cpp file, u will surely get the error LNK2005.

my suggestion is, u move the delclaration to stdafx.cpp .

Of course, you named your global variable "Globalfedit"
So fedit doesn't exist.

No problem. But remember to use "extern" if you want to use the global variable from another source, else it will be defined more than once.

Select correct product version when double clicking from explorer

Hello All,

I have a bit of a dilemma. I am faced with the situation that I need to open the correct version of my product when side-by-side installations exist. The situation occurs in that my file extension has not changed in the two released versions I have; so using Windows file association the last installed version will be the one that always gets associated and therefore, and this is not good enough in my clients eyes. What I looking for is that a version 1 file of extension .xxx will open with version 1 of my product, but opening a version 2 .xxx file will open with version 2 of my product.

I am not sure about a good approach to doing this as I can't seem to find any documentation that would help out here. I have noticed that VS 2005 has a version selector that enables it to figure out which version needs to be opened (and even gets the Icon correct!). But it is not really documented and I am not 100% sure how this would be been implemented.

Does anyone have any ideas on the best method of solving this problem?

Thanks in advance.

Ben

Hello. A thought:

You could make a third program. And register the extension to that program. The new program determines what version to start, and then starts the correct version.

Open Ports Windows XP

I want to get information about ports on my system including the following:
- ports that are used
- processes that use the ports
- what data (binary) the processes send via the ports

Are there any APIs that can help me?

Thank you!

Are you looking for a toool or code?

for information about ports, you can use "tcpview" tool from sourceforge.net

Just google it.

anyway the task you specified will not work with an API or two

especially this one! look for some sniffers.

Installation of MSDN?

If i don't want to install the MSDN for the second time, what should i do?
It says that my system is installed on C: and all files of MSDN are installed on D:, after i reinstall my operating system, of course, all registry infos of MSDN were gone. But all files are still exist on drive D:, and i don't want to install MSDN again, what should i do for my purpose? Confused | :confused:

Nobody trust it, but it is true.

I strongly suggest you to re-install MSDN. Frown | :(

Actually document explorer is loading the help collection. the exe will be available at Microsoft Shared folder.

The command line information for the the exe is as follows.
"C:\Program Files\Common Files\Microsoft Shared\Help\dexplore.exe" /helpcol ms-help://MS.MSDNQTR.2004OCT.1033

Try this way but im not sure whether it will work properly or not Smile | :)

Thanks, but i am just wanna know that if there is a way to use the data files of MSDN, all data file(*.chm) is on the disk, why we can't use?? Why we must re-install the MSDN, that's so boring to re-install it! If we can do it, just copy all data file to a disk and invoke these data at wherever we want, don't you think that's great? such as, win98,win2k,winXP and so on.
I mean if you setup multi OS on your PC, and you need only install MSDN for one time, and then can use it under any OS you installed.

Can this become true? Smile | :)

Hi,
I can able to create controls for a dialog box at run time. But how to create controls that are created automatically when scrolled. The help i need is that i will create some 10 buttons in a dialog while in its initialization. All the 10 buttons each will have one edit box beside. On clicking one button some text will get displayed on its associated edit box. Initially the scroll bar will be disabled. But if one button is clicked, the scroll bar should get enabled, and one more button and edit box have to be created (that is, 11th button and its edit box...). Please help me in this!! Cry | :((

Thanks in advance,
Sangeetha.
