I check this MSDN answer but

According to this[^] link in MSDN either your computer has insufficient resources (not enough RAM etc.) to complete the task at hand or your user priviledges are set too low.

First thing to check is your user priviledges. If that does not help then make sure your PC meets the minimum requirements for VS2005.

My computer is meets the MSDN minimum requirements.

About check user privilegs - please tell me how to do it, so I can check.

Thank you very much for answer,

Assuming you are using XP

Control Panel
->Administrative Tools
->Computer Management
->System Tools
->Local Users and Groups
->Users

Find your user name in the list, right click, select "Properties"
Select "Member Of" tab

Which group are you a member of?

Sorry, I am at a loss and cannot help

29-Oct-06 3:38

I'm using win XP Home Edition.

In Local Users and Groups I don't have "Users" but in Users in the Control Panel I check, and my user have admin properties (There is only one user in the computer).

The VS still don't building my projects ....

I am sorry, but I have never had the problem you are encountering and other than my interpretation of what MSDN says about the problem I have no experience to guide you farther. I hope someone else on this board can help you.

I usually do not endorse cross posting but maybe you could try asking on the Visual Studio[^] forum if you do not get an answer here soon.

I found the way to fix the problem, and I've been started to learn VC++.NET.

The solution was:
1. In Computer Management, select device manager.
2. In View select show hidden devices.
3. Then you need to locate The Null device in the list of Not plug-and-play device managers.
4. As you find it you double-click it and validate it working properly and running (in device manager tab -> device status).
5. In the registry go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Null
and validate Hexadecimal-Value Named "Start" exists and had the value 1 (in hex).
If not - add it.
6. Restart your computer.

Now is the big problem :
========================
According to step 4 above, the Null device may not working properly (like I did).
To fix it you double-click it and choose to remove this device.
Then you doing steps 5 and 6 above.

After you restart the computer you need to run the Visual Studio Setup in repair mode - This will reinstall the Null device properly.

Restart your computer, hold up your fingers and pray to god when it restarts Poke tongue | ;-P

After you restart the computer you can Build and even Run your C++ programs in visual studio !!!

Boolean Size?

Why the variable bool is implemented as 8 bits ? 1 or 0 can we say it with 1 bit? or the minimum size the system can allocate comes in "Bytes" ? Unsure | :~

Yes, the smallest unit that the computer can store in memory is a BYTE. Although you can work with bits if you use the bitwise operators.

String Split

Imagine I have a string like "code,project,bob,vc++" and I have array or vector like
vector<string>vec_strings;

Is there any function that lets me break the words with "," delimiter and put them into the vector automatically? I prefer to use STL.

Hi friends,
I have a export function in the DLL.
When this function is to be called from other application,
it has to show the form in which the DLL was built with.
Can anyone help out?

For example

//DLLMain.cpp file
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)
{
//what code should I write to show the form

}

//GraphDlg.cpp
class CGraphDlg : public CDialog
{
// Construction
public:
CGraphDlg(CWnd* pParent = NULL); // standard constructor

// Dialog Data
//{{AFX_DATA(CGraphDlg)
enum { IDD = IDD_GRAPH_DLG };

// NOTE: the ClassWizard will add data members here
//}}AFX_DATA

// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CGraphDlg)
public:
virtual void OnFinalRelease();
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL

// Implementation
protected:
HICON m_hIcon;

// Generated message map functions
//{{AFX_MSG(CGraphDlg)
virtual BOOL OnInitDialog();
afx_msg void OnPaint();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

Show the dialog modal or modeless?

To do it modally, something like:
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)
{
CGraphDlg GraphDlg(NULL);
if (IDOK == GraphDlg.DoModal())
{
//user clicked "ok" - do something
}
}

You may want to pass a parent window pointer to the dll function so the dialog will have a parent.

As this function is called repeatedly in the calling program,
modalless dialog is needed.

<br />
//MyDLL.cpp<br />
CGraphDlg *pDialog;<br />
<br />
BOOL CMyDLLApp::InitInstance()<br />
{<br />
pGraphDlg=new CGraphDlg;<br />
pGraphDlg->Create(IDD_GRAPH_DLG,NULL);<br />
return TRUE;<br />
}<br />
<br />
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)<br />
{<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState());<br />
pDialog->ShowWindow(SW_SHOW);<br />
}<br />

But this code does not show the window.
I get Assertion Error.

The calling application is a C program.
So cannot pass the window pointer to the dll function.

Thanks for your answers.

The assertion is probably because the dialog has not been created.
Where do you call pDialog->Create()?

We use Microsoft Visual C++ 1.52. You can get it if you have an MSDN subscription.
