A dirty hack could be to create an installer for your application, that grants access to everyone to the application folder.

One have to be an administrator to install the application, but then any user can use it.

Hi,

I recommend that you don't use Excel Interop because it has many known issues, especially when used in web applications.

You could check out GemBox.Spreadsheet .NET Excel component for reading and writing XLS, XLSX, CSV, ODS and HTML files.

It is independent of Excel, light on resources and extremely fast.

It also supports advanced scenarios like Excel export/import to DataTable so you can easily bind your Excel files to UI controls with data binding.

Save Excel to ASP.NET stream web demo demonstrates it's usage in web application.

I think you should search for simple socket based application, or try to create some client-server based application before actually jumping in Internet relay chat arena....

Frankly speaking, it will give great help and knowledge to you, once you able to make urself a small chattign application.

Have a look at Beej's guide to networking programming[^], another starting point is the Winsock Programmer's FAQ[^], both come with examples. The rest is IRC protocol specific,

CString class holds just a string (array of characters). It doesn't have any color information associated with it.

How are you displaying the string ? As already mentioned by somebody else, CString is just a class containing data and doesn't have any relation with how it will displayed.

What you want is a different color for a word.
You can only disable/enable windows and not words.
Also as Rejeesh said, you cannot do that with a CString alone.
You could use a control similar to a rich edit control and show one word with a different color.

If you are using the string in pDC->TextOut (...) you can do it as well by changing the font color, but you can't do it only depending on words, you will need different strings, so you print one, change the color and then print the next.

this[^] or this[^]may be useful for you as well.

One way to store colour information in a CString is to use HTML tags and then dump the string into a HTML enabled control.

-or-

Use RTF codes and dump into a Rich Edit Control.

Another way to store color information in a CString:

Im using following code to reduce the dialog width.it show assertion error

void CToolTab::ReduceWidth()
{
	this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);
}

assertion error in bolded line

BOOL CWnd::SetWindowPos(const CWnd* pWndInsertAfter, int x, int y, int cx,
	int cy, UINT nFlags)
{
	ASSERT(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL));

Here m_hWnd shows 0x0000.
Im reducing the width after pressing button in the same dialog.

From which function are you calling ReduceWidth()?

Re: Assertion error in SetWindowPos()

3-Jan-10 19:36

I believe you're calling SetWindowPos in a place where the window has not been created yet.
Is it in the WM_SIZE handler?

Add a condition before you call SetWindowPos.

if (::IsWindow(this->m_hWnd))
    this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);

actually im using WPF C# dll in vc++ code.
In that dll i have button ,so the button handler calls collapse() delgate fucntion.
in VC++ im coding like

Tabcontrol::ToolBar::Collapse += gcnew Tabcontrol::ToolBar::Navigation(OnCollapse);

void OnCollapse()
{	

	CToolTab tab;	
	tab.ReduceWidth();
	
}

void CToolTab::ReduceWidth()
{	
	if (::IsWindow(this->m_hWnd)) 
		this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);
}

But my cursor get out form the IsWindow linw.Because m_hWnd shows 0x0000.
Then how can i use this SetWindowPos?
In OnInitDialog im using SetWidnowPos as follow
SetWindowPos(&CWnd::wndBottom,0,80,300,800,SWP_SHOWWINDOW);

'tab' variable in OnCollapse() is local to OnCollapse(). The 'tab' variable will get destroyed after OnCollapse() call.

By declaring CToolTab globally,its not working.
