Sorry about that. It is sometimes a bit tricky to dig up the correct terms, when you get a new tool in your right hand and task to do in your left. Some sort of guidance on the tool and terminology would be optimal, but unfortunately in this case there were none. Example would have helped a lot.
However, you guessed just fine, and that gives me nice keywords to hit into the google search-field. Thanks!

I create a "Windows Form Application" projects that names p2pport.
Dlg is my form file name.
The following two lines are in Dlg.h.
struct sockaddr_in addrLoop;
CClient *cnList[5];
But it comes some errors.
error C4368: cannot define 'addrLoop' as a member of managed 'p2pport::Dlg': mixed types are not supported
error C4368: cannot define 'cnList' as a member of managed 'p2pport::Dlg': mixed types are not supported
Do anybody know what's wrong?
Appreciate your reply. Thx.

Yes, mixed types are not supported. If you had studied C++/CLI, this means reading things likes books and articles you would know what that means. There is actually a great series of introductory articles on the subject right here on Code Project. I suggest you read them.

Hi,
I have to get handle for a process.I am doing as below.
Process^ pc = Process::Start("AcroRd32.exe", strCmdArgs);
IntPtr ProcHandle = pc->Handle;
HWND hwndProc = (HWND)ProcHandle.GetHashCode();
HMENU hMenu = ::GetMenu((HWND)&hwndProc);
// When I debug Iam getting Undefined Value in hMenu.
Is my code correct? Any suggestions would be helpful.
Thanks
Today is a gift, that's why it is called the present.

Just guessing... HWND hwndProc = (HWND)ProcHandle.GetHashCode();
That doesn't seem right to me, I don't remember ever using GetHashCode to obtain a HWND.

First, I know there is a known bug related to this warning message, and I know I have to call Microsoft to get the hotfix. My project is written in C++/CLI, with reference to 3 small C# DLLs. I've been working with the project for 6 months with NO warning messages. As soon as I installed VS 2008 Beta 2, BOOM! 350 warning messages, all C4945.
I am positive VS2008 is at fault, because on my other machine, which has ONLY VS2005, the project still builds with no errors.
Has anyone else ever encountered the same problem once VS2008 is installed? Does anyone know if uninstalling VS2008 will roll things back effectively enough to alleviate my problems? I'm just not excited about having to sit on hold with MS support for half an hour to get a hotfix because they're too darn stubborn to just post a !%@#($*&!@#($ download link.

If you can put together a small project that demonstrates/reproduces this as a legitimate
VS 2008 bug, I can forward it to MS for you. If it's a bug, this should be simple -
you know the symbols involved.
This issue is currently NOT reported for the VS 2008 Release Candidate, so if it's still
an issue, we should get it in there!
Also check and make sure you don't have a genuine namespace/symbol-name collision

Mark,
I appreciate the offer, but it sounds like I didn't clearly express my problem and suspicions.
I am not claiming to have found a VS2008 bug. My idea is that the VS2008 INSTALLER somehow blows up my installed VS2005. The build problems occur in VS2005 -- the environment my project was created in. I have not tried porting the code over to VS2008.
There are 2 reasons I'm blaming the VS2008 installer: (1.) my project built fine before I installed 2008, (2.) on my other machine, where I have NOT installed 2008, the project continues to build fine without the aid of a hotfix (as addressed in KB922271). This seems to rule out any coding or project configuration problems.

Ohhh, ok. Sorry for the confusion.
I'm not sure what's up with a side-by-side install of 2008 B2 with 2005.
I never installed the B2 version.
What does the readme say about installing with 2005?

I need to be able to track a mouse's mmovement within a dialog that has several (10) EditBoxes. Since it would not be practical for the User to have to tab several EditBoxes to get to the one he/she wants to enter data into; the EditBoxes are not Tabed. I need to know where the User is (in what EditBox) so that the proper function call is active for the users input. This is actually a Wizard-style property page so there is no OK button to poll for; and the User is not required to use any of the EditBoxes on any given page. Hence the need to know when ther User has Started entering data in what EditBox.
Help with usable code examples would be appreciated. (Note: I am using VS 6.0 in MFC.)

I'm guessng you;re in the wrong forum. However, either way, if you tried something, post the code so we can correct it.

Anyone want to make $25-30/hr tutoring me via phone? I just installed Visual Studio 2008 Beta 2 and I am looking for someone to help me come up to speed on C++, C# and VB. I haven't touched Visual Studio since 6.0, so I am a bit out of date. Also, I'm entirely self-taught, so I would like someone who can show me how to start from scratch and set things up 'correctly'. My focus is on creating a simple C++ form app using CLR specifically for Vista. I need to know the correct method for reading/writing files, and I would like to learn how to use RegisterPowerSettingNotification to catch the WM_POWERBROADCAST message in C++, C# and VB. If you can control a serial port, that would be great too.
Currently I am creating an application to control my home projector, but this is really just to help me come up to speed again. This can be done in off-hours late nights and weekends and I can pay via paypal.
My email address is ima_computer@yahoo.com
Thanks!
- Ed

I have to use the serial COM-Port with managed C++, but I can not find any project.
On CodeProject I found the articel "How to open a serial COM port in Managed C++", but I allways get a exception.
So, please, has somebody a managed C++ project with COM?

I have no experience with this subject, but if I need to solve your problem I would look for samples/examples in C#. It is simple enough to translate C# code samples of the BCL usage into C++/CLI.

Not intrinsically. What is your background? This is a C 101 topic. C arrays have no length data in their structure, period.
Also this is the wrong forum for a pure C/C++ question. See the message at the top of the forum "The C++ / CLI is for managed and mixed-mode C++ programming only", open it up and read it, it won't hurt you.

Hi,
I have a BYTE pointer it contains the values that i have read from a jpeg file. how can i convert it in to a BYTE pointer of grayscale image.
Thanks in advance

Well, I assume you're askng in te wrong forum, but if you aren't, then the Bitmap class is how you convert a JPEG to an in memory image, and you can convert to greyscale with a color matrix. You can then save the resultant image as a stream, giving you a JPEG byte array again.
But, if you're n the wrong forum, you need to find another way to read a JPEG, convert it to grey scale and save it as a JPEG again.
