the problem with executing sql commands is that it dont return a value. for example if im trying to retrieve the data of a particular record. do you have methods of doing it.

AFAIK you put the same question many times last days.
One answer with exampe code, using MFC class CRecordset directly without inheriting, I gave you HERE[^].
What's the problem? Doesn't work? Hard to read? Looks ugly? Not enough speedy?
Have you even tried it?

yes you have given me that code before, and i thank you for that... But i need speed now... and you use the forwardOnly attribute, which means i have no bi-directional scrolling... and if the database has 400 records it would take a time to get to the end...

Life is simple, you just complicate things... 
Well, I have used forwardOnly in my example just as an example and it's not intended to be copy/pasted.
Put what you wish instead. Is that a problem?
Although 400 records are not so much in real programming world, if you want a little bit more speed, use ADO instead of MFC database classes.
And if you really really need much more speed use the database native C APIs (if any available).
HERE[^] is an example of MFC wrapper classes built around MySQL C APIs. Very very speedy...
If you are using another database than MySQL, sorry but I have nothing available for the moment. You have to dig yourself for the sake of speed.
BTW. Are you really, really need "bi-directional scrolling" for your recordset?

yes i kinda need it very much... so i could easily navigate through my database... thanks my question is answered

(continued)
When dealing with databases, one of the issues that can increase queries speed in a way you have never dreamt  is to optimize the database structure itself, as for example creating indexes where necessary.

Take a look help docs on CListCtrl::GetViewRect() and CListCtrl::GetItemRect(). If you are using a view derived from a CListCtrl you can access the member functions using GetListCtrl(). If you are accessing a control, do it through a member variable. For example:
m_cMyListCtrl.GetItemRect(0, rect, LVIR_LABEL);
Since a CListCtrl is a member of CWnd you can also access the entire controls client or window rectangle using GetClientRect() or GetWindowRect().
There is an very good article here on using list controls[^]

what im trying to do is give my listctrl a gradient background so it blend in with the dialog but i dont seem to be getting anywhere.

How to send and receive data use the same port?
alantop
|
|
|
|
|
what type of xfer and client or server??
|
|
|
|
|
and are you talking about send files or just communcating...?
|
|
|
|
|
//basic send and recieve is...
#include <string>
#include <winsock2>
#pragma comment(lib,"ws2_32")
WSAData wsaData;
WORD wVersionRequested;
wVersionRequested=MAKEWORD(2, 2);
WSAStartup( wVersionRequested, &wsaData );
std::string rawcmd;
SOCKET communcationsock;
SOCKET ListenSocket;
SOCKADDR_IN service;
ListenSocket = socket(AF_INET, SOCK_STREAM, 0);
service.sin_family = AF_INET;
service.sin_addr.s_addr = INADDR_ANY;
service.sin_port = htons(21);
if (bind( ListenSocket, (SOCKADDR*) &service, sizeof(service)) == SOCKET_ERROR) {
printf("bind() failed.\n");
}
listen( ListenSocket, 1 );
communcationsock=SOCKET_ERROR;
while(communcationsock == SOCKET_ERROR) {
communcationsock = accept( ListenSocket, NULL, NULL);
}
bytesRecv = recv( communcationsock, CMD, 128, 0 );
rawcmd.assign(CMD, bytesRecv);
if(rawcmd=="..."){
char onconn[128]="Can You Hear Me\r\n";
send( communcationsock, onconn, strlen(onconn), 0 );
}
//Basicallly you have to open up a socket for communication.. then you can open up //another sock separately and send files using the same principal.

Hey,
I'm trying to make a move from VB.NET over to C++ (Visual Studio 2003). I'm not new to programming, just programming in C++. I've read through about 10 tutorials over the last week or so and none of them explain how to do graphic stuff. I need to essentially recreate the GUI from my VB.NET application where it colors in defined regions and has drag and drop that knows when you drag something onto that specified region.
Is this possible? (obviously it's possible, but if it takes writing like 100 different function and classes and libraries, it's not really possible).
If anyone can suggest a starting point, I'd be very greatful.
Thanks all!
Mike

I am curious, why do you "need to" do that?

Umm... I'm moving the game from vb.net to c++ so I need an interface I suppose. It has to be drag & drop and has to be able to have colored in regions because that's how the game is played. I'm not sure what you're getting at? /

No, I am not sure what you are getting at. In your first post you said you "need to" I wondered why you needed to port the application to C++ from VB.NET.
The C++ environment supports .NET development so the port from VB.NET to C++.NET should be a 1 to 1 port. The .NET class library is exactly the same in VC++.NET as in VB.NET.

I know the number of lines that I have in my document, but the number of pages will depend on the font size, spacing, margins, etc. Is there an easy way to determine the number of pages? A quick comment or code summary with a reference to relavent sample code would be greatly appreciated. Thank you.

You should be able to calculate the number of pages inside OnBeginPrinting(). Call pDC->GetDeviceCaps(VERTSIZE) to find the vertical height of the paper in mm. You should then be able to calculate the number of pages from the number of lines, the font size and the page size. Here is what I do...
void CActionManView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
m_nHeight = 32; Font size
m_normalFont.CreateFont(m_nHeight, 0, 0, 0, FW_NORMAL, FALSE, FALSE, 0, ANSI_CHARSET,
OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,
DEFAULT_PITCH | FF_DONTCARE,"Ariel");
pDC->SetMapMode(MM_LOMETRIC); // 0.1mm units
int height = pDC->GetDeviceCaps(VERTSIZE) * 10; // Get size of page in mm and scal to 0.1mm units
m_nItemsPerPage = height / m_nHeight; // Calculate items per page
m_nItemsPerPage -= 10; // Allow for header/footer
unsigned int nNumPages = (GetPrintableTaskCount() /m_nItemsPerPage)+ 1;
pInfo->SetMaxPage(nNumPages);
m_nPrintItemIndex = 0;
}
Hope this helps.
