For my current application (MFC C++ dialog)I was generating my own database, just a large array of type Struct (name, address, cost, code etc - CStringArray, CStrings, ints and doubles) and initialing it at startup via a Tab delimited file. The program will then add more records as required.
The reason for moving to mySQL is one of speed and its free.
I was just using the CStringArray class to store the names of items and do all the searching; e.g. string searches and the array was getting quite large and I was getting worried about speed as the database grows.
I have just unstalled mySQL 4.1 onto my PC (runs a dos window - that's as far as I have got), and I have just started reading the syntax & commands for SQL. Does anyone know of any good introductions/tutorials, i.e. sample projects using mySQL with an MFC C++ Visual Studio .Net 2002 program. Also I would like to populate the mySQL database with this Tab delimited file is that possible?
So any information/tutorials most welcome.
A sample project using mySQL would be great, as from web searches they seem to be problems with different versions of Visual Studio.

Hi!
I just killed my MSDN. But I need to continue the work now.
So I have a trivial question.
I need a messages to be send to listbox to get info about selected items and get these items too.

MSDN Library is on line at microsoft.com. If you are on line then you have access. If you do a search, via Google, on anthing to do with MS Windows programming, the odds are you will get links to the MSDN Library at Microsoft.

I am not sure that I should write this here, but...
is it possible to listen to port 135 without getting a error 10048 or aother port that windows use.
I have tried to use sockets, didn't work.

No, it isn't. Of course you could use a sniffer if you want to know what's going on on the network however only one socket can listen on a given port at a given time. That's why you're not supposed to listen on well known ports (see Port Numbers (IANA)[^] or Port Assignments for Commonly-Used Services[^] for Windows specific services) unless you implement that service.

Well how does a sniffer listen on these port?
If I create a service would i then get access to them?
And Thanks

That I don't know. However if I were you I would try to find out how an existing sniffer works. Maybe you should check out WinPcap[^], the packet capture library used by the Windows version of Ethereal[^].

First of all, I assume that you know what you are doing. If you just randomlly picked port 135, then you need to learn more about networking before you continue. Since I'm assuming you know what you are doing, warnings about how doing this can have really really bad effects on your system, even making it unuseable, are redundant.
Port 135 is the dcom-scm. So you need to disable it. See:

Google will give you more links

Well, if you start that project to learn more about networking I'd say it's a good idea. But if you just want to do it because you need a tool like that I'd say it isn't worth the trouble. A good firewall will let you know when an unauthorized process tries to listen/connect. And for detailed analysis of what's going on you can use a tool like Ethereal.
Best regards

Hi all.
I got a simple problem using CString, but I can't find a good solution for it.
I have a Database with a field (10 Bytes long) as a CString (using MFC ODBC).
and I need to get and set the Values of each byte.
Example:
CString text = "ABCDEFGH90"; I can get the values by using text.GetAt(0);
But if I code a staement like this I just get a lot errors..
if (text.GetAt(0) == "A") <- compiler error
or if I like to set a value
text.SetAt(0, "T") <- compiler error
What is the best way to do it without having trouble to convert the hole stuff to const char and back ??
Big THX. for helping me out !!!

"A" and "T" are strings not characters.
'A' and 'T' represent character values.
if(text.GetAt(0) == 'A)) <- no error
text.SetAt(0,'T') <- no error.

This program reads .bmp files and like types them in a game screen. I would like it so to be activated by dragging a crosshair over the game screen so the program knows where the screen is
The game I am talking about is runescape.
This program would read the .bmp and type the word in and then press the key enter
If you would like to see a program like this I will show you
My email is dellnerd88@yahoo.com or aim is nellyeminem88
If you want me to explain it more email me

Hi,
Can anyone please help me with this problem?
I have a dialog with a CRichEditCtrl and a button.
The user highlights a piece of text and clicks the button.
When the button is clicked, a modal Dialog is created.
This modal dialog has a CEdit and a button. The CEdit contains a variable of type CString.
The user enters text in this CEdit.
When the OK button is clicked, the text in the CEdit should replace the highlighted text in the CRichEditCtrl in the initial dialog.
When the program is executed it gives a "Debug Assertion Failed" error.
The assertion is as follows (from AFXCMN.H):
<br />
AFXCMN_INLINE void CRichEditCtrl::ReplaceSel(LPCTSTR lpszNewText, BOOL bCanUndo)<br />
{ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, EM_REPLACESEL, (WPARAM) bCanUndo, (LPARAM)lpszNewText); }<br />
My code is as follows:
<br />
void MyModalDialog::OnBtnOk() <br />
{<br />
CString returnStr = m_edit;
MyProjectDlg dlg;
dlg.m_fileContents.ReplaceSel(returnStr, FALSE);
}<br />
Thanks very much,

Do not try to replace the text from within the dialog. Replace the text after the dialog closes, it is easier.
MyProjectDlg dlg; // dialog type now exist
// but the window does not exist yet
// therefor, you can not send it any messages.
According to your comments: The MyProjectDlg should already exist and it should be lunching the MyModalDialog, but here you are asking MyModalDialog to create a new MyProjectDlg and replace the selected text in that (which also does not exist).
void MyProjectDlg::SomeFunction()
{
MyModalDialog dlg;
dlg.MySetText(...);
if( dlg.DoModal() == IDOK )
m_fileContents.ReplaceSel(dlg.MyGetText(), FALSE);
}

programatically or by using the windows explorer search/find ?
programatically, use CFileFind ( or FindNextFile and FindFirstFile )

Get a copy of "Agent Ransack", it can find anything. There know there was an article here some where, but I can not find it.
You could write your own using the MS-C functions _findfirst() and _findnext() or the SDKs FindFirstFile() and FindNextFile(). The hard part is switching directories, for further searching. All the "File I/O Functions" functions are listed in the MSDN, you'll have to do a search for that exact string (not listed in index - as usual).
P.S. There is an article on "Agent Ransack" at CP.
Good Luck!
