I use this easy way, but it is not recommended for large strings.
String ^s = "Hello world";<br />
CString str = s;<br />
WCHAR *w = str.GetBuffer();<br />
WCHAR *myChar = new WCHAR[str.GetLength() +1];<br />
memcpy(myChar,w,str.GetLength()*sizeof(WCHAR));<br />
myChar[str.GetLength()] = '\0';<br />
<br />
AfxMessageBox(myChar);

Can anyone tell me the difference between Storage Class and Storage Class Specifier?
Thanks and Regards

In C++, the storage class specifiers auto, static, register, extern, and mutable. The storage class specifiers explicitly determine the storage class of a variable. Thus, the storage class specifier, auto, lets you define a variable with automatic storage (storage class). However, you will also hear: auto storage class. So, storage class and storage class specifier may be used to mean the same thing.

According to your profile, you program with C++ and not C++/CLI. Also, your plea for help does not give me enough information to assist you. What are your requirements? Here is an example of how your plea for help sounds to me:

You might be able to run it with wine program in Linux. Your better bet would be to ask in a Linux forum

Hi ,
My problem is that, I want to run an .exe from the windows service. But the application window is not visible to the user. Exe and Service is running in task manager. Previously I was using CreateProcess funtion. Then after getting suggestion from this site, I changed that into CreateProcessAsUser and the Code is like below. But Still I am facing same problem.
BOOL b;
HANDLE hToken;
HANDLE hNewToken;
b = OpenProcessToken(GetCurrentProcess(), TOKEN_ASSIGN_PRIMARY|TOKEN_DUPLICATE, &hToken);
b = DuplicateTokenEx(hToken, TOKEN_ASSIGN_PRIMARY|TOKEN_ALL_ACCESS, NULL, SecurityImpersonation, TokenPrimary, &hNewToken);
b = CreateProcessAsUser(hNewToken, NULL,ArgPBU,NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS | CREATE_NEW_CONSOLE, NULL, Cwd, &si, &m_piPBU);
CloseHandle(hNewToken);
-------------
After executing this I am getting same result.

Does your service have a main or a WinMain entry point? Also, you should post this in the Viaual C++/MFC forum.

i'm new in C++ but i'm a Borland C++ user, is that same with C++/CLI ?
Can anyone help me make bouncing ball with the Borland C++ program ?
i beg all the readers
thanks before

Borland C++ is not managed. C++/CLI is managed. Thus, you are in the wrong forum. Also, you may have better luck asking your question at a Borland C++ message board.

Hello,
I am trying to do a GetPixel in a image embebed in a PictureBox.
If I have a Bitmap it is posible to do a GetPixel, to get the COLORREF of the pixel clicked, but in a PictureBox I can't do it.
Does anybody knows how to get the color of a pixel clicked in a picturebox?
Thanks in advance
|
|

|

A picture box is NOT a picture. It DOES have a property that exposes the bitmap it's displaying. I presume you can call a getpixel method on that.

Ok, now I see,
I have done it as follows:
I load the image in the picturebox:
pictureBox->Load("C:\\image.png");
and after I load it like a bitmap in the event that I want, in my case pictureBox_MouseUp
<br />
Point^ Point1;<br />
Bitmap^ Bitmap1;<br />
Color pixelColor;<br />
<br />
Point = e->Location::get()<br />
Bitmap1= gcnew Bitmap( "C:\\image.png",true );<br />
pixelColor = Bitmap1->GetPixel(Point1->X,Point1->Y);
This is the way that I did it,
Thanks for your help

Which bit are you stuck on ? Are you really using C++/CLI, or are you in the wrong forum ?

I recently downloaded Visual C++ Studio and when I try to compile my project, I get error messages such as these below. I made sure to follow the instructions on setting the VC++ Directories option but I still keep getting errors such as this one
c:\Pam 2\Headers\afxwin.h(19) : fatal error C1083: Cannot open include file: 'AFX.h': No such file or directory
and the problem is that most of these include files happen to be in the Windows Platform SDK / Include/MFC folder. How do I get my the compiler to look in there for these files please.

First of all, you're in the wrong forum.
You set the paths in the options for VC2005.

You have downloaded Visual C++ Studio? I think it is VC++ Express edition, which does not support MFC. (Afx.h). You need to retail version to do MFC programming. The express edition only supports Managed c++.

Hello
I am very new to managed c++, i have to start the codeing which needs many MFC features. I have done the same in VC++ 6.0. Now i must port it onto VC++.net.
Can anyone please confirm me wheather, i can start my project in VC++.net version (Managed C++) and also use the features of MFC.
Kindly give me the method i need to follow.
Thank you
Kind Regards
Sandy

Yes, you can create an MFC project and add the ( from memory ) /clr compiler switch to allow you to use managed code.
However, MFC doesn't offer anything that .NET doesn't offer, are you sure you want to rely on both ?
