Hi!
Thanks for your reply. I used the following code and get these two errors:
bool connectionStatus = InternetGetConnectedState(INTERNET_CONNECTION_OFFLINE,0);
Errors:
d:\downloadversion\downloadversion\Form1.h(31) : error C2065: 'INTERNET_CONNECTION_OFFLINE' : undeclared identifier
d:\downloadversion\downloadversion\Form1.h(31) : error C3861: 'InternetGetConnectedState': identifier not found
I'm using Windows Forms.

You'll need to include a header, and link to a library to use this function. Scroll down to the "Requirements" section of the MSDN link I provided you with.

Hi!
It's told that minimum supported client and server as Windows 2000 Professional and Windows 2000 Server. Will it work with Windows XP?
Do I have to download the following to my Solution path?

Wininet.lib
Wininet.dll

Windows XP was released after Windows 2000. So, the API will work on XP.

If I include the above code, I got 283 errors, all in the Wininet.h file(Syntax errors, missing type specifier errors and error C2378: 'HINTERNET' : redefinition; symbol cannot be overloaded with a typedef). Where shall I get the Wininet.h file? Do I have to Download and install Windows SDK to solve all these errors?

After I included "windows.h", all the errors vanished. Thanks alot.

Hi,
I have one dialog base application. It contains list control having some data in report view. After double
clicking on it a new modeless dialog gets opened. It contains edit controls which contains data of list
control's selected row. If i edit data in edit controls and press OK then data in list control should get
updated with newly updated data.
My problem is how I pass updated data to list control of parent dialog.
I am using Microsoft Visual studio 6.0.
Regards
Nikesh

Implement an appropriate method in the parent dialog (the parent dialog, upon creation of the child one, should pass to the child a pointer to itself).
See this CodeProject's article:"Dialogs Communication"[^].

When creating the modeless dialog, you have to specify a HWND that owns the new dialog; enter the HWND of the dialog containing the list control here.
You can use the GetParent[^] function to get the parent window HWND when the OK button is clicked on your modeless dialog. Use GetDlgItem[^] to get the HWND of the list view.
Now you can use SendMessage[^] with LVM_INSERTITEM[^] or LVM_SETITEM[^] to add/edit data in your list control.

Hi all,
i'm attempting to connect to a foxpro dbaseIV via odbc. I was able to connect to it by specifying the physical path of may table (i.e C:\test\f_cheque.dbf). but for some purpose, i have to connect to that base without specifying the path, just by alias (odbc).
did some one know how to do that by C++. Thx

You should create a DSN (see, for instance "Creating a new ODBC DSN"[^]), then.

My mistake is that i missed to include the alias into the connectionstring.
Thx for the reply.

m_pDC.TextOut((1 - m_nHScrollBarPos) * m_cxChar, i * m_cyChar, szFormatted);
}
A bit unclear description.

Do you want to know how to display ellipsis at the end of the string if it's too long? You could use CDC::DrawText()[^] with DT_END_ELLIPSIS formatting instead of TextOut().

If, on the other hand, you want to be able to select portions of the text, you would be better off using an edit control. You can style them to look like you need them too (mostly true), removing frames and such.
If you want to let the user only select the entire text, you could respond to WM_LBUTTONDOWN events within your text rectangle, and redraw the text with a different background color set in the DC.

thanks
i am very new to MFC. trying to select the particular text of the client area.i have use
OnLButtonDown and OnLButtonup had two points .i am not able change background color of particular text.provid me some example .....
|

You use CDC::SetBkColor()[^] to set the background color.
You will have to draw the text in more than one go to make parts of it appear selected. Have a look at CDC::SetTextAlign()[^] using the TA_UPDATECP flag to make multiple calls to TextOut() create one line of text.
I still think using a CEdit might me a lot easier.
Use CDC::GetTextExtent()[^] to calculate width of characters in your string.
