still the same problem ---
ipList.DeleteItem(i);
s--;

Relpace the codes with:
if (i != -1 && lstrcmp(ipList.GetItemText(i), temp.psz) == 0)
{
ipList.DeleteItem(i);
}

thanks, both the problems are solved.
BYTE m_M1, m_M2, m_M3, m_M4;
TCHAR ss[50] = {0};
UpdateData();
int i = -1;
LVFINDINFO temp;
ipAdd.GetAddress(m_M1, m_M2, m_M3, m_M4);
temp.flags = LVFI_PARTIAL|LVFI_STRING;
_stprintf_s(ss, _T("%d.%d.%d.%d"), m_M1, m_M2, m_M3, m_M4);
temp.psz = ss;
i = ipList.FindItem(&temp);
if(radBut1->GetState())
{
if(m_M1 && (i == -1 || lstrcmp(ipList.GetItemText(i, 0), temp.psz) != 0) )
{
ipList.InsertItem(s++, (LPCTSTR)ss);
ipAdd.ClearAddress();
}
}
else if(radBut2->GetState())
{
if (i != -1 && lstrcmp(ipList.GetItemText(i, 0), temp.psz) == 0)
{
ipList.DeleteItem(i);
s--;
}
else
MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB_ICONWARNING | MB_OK);
ipAdd.ClearAddress();
}

I think your code still has some problems.
Consider the situation below:
There are two items in CListCtrl.
111.111.111.111
111.111.111.11
And you enter 111.111.111.11 to insert the new item, see what happen.
If I am right, it will insert successfully!!That may not be what you want.
|
|
|
|
|
in that case, 'i' will not be -1 and lstrcmp(ipList.GetItemText(i, 0), temp.psz) will be equal to zero because the item text and temp.psz will be same.
|
|
|
|
|
Before you changed the "temp.flags = LVFI_PARTIAL|LVFI_STRING;" to "tem.flags=LVFI_STRING;", it's a wrong case exactly.
But now it isn't.

BYTE m_M1, m_M2, m_M3, m_M4;
TCHAR ss[50] = {0};
UpdateData();
ipAdd.GetAddress(m_M1, m_M2, m_M3, m_M4);
_stprintf_s(ss, _T("%d.%d.%d.%d"), m_M1, m_M2, m_M3, m_M4);
int compare;
for (int i = 0; i < ipList.GetItemCount(), ++i)
{
compare = lstrcmp(ss, ipList.GetItemText(i));
if(radBut1->GetState())
{
if(m_M1 && m_M2 && m_M3 && m_M4 && compare != 0)
{
ipList.InsertItem(s++, (LPCTSTR)ss);
ipAdd.ClearAddress();
}
}
else if(radBut2->GetState())
{
if(compare == 0)
ipList.DeleteItem(i);
else
MessageBox((LPCTSTR)L"Error: Address not found", (LPCTSTR)L"Delete Address", MB_ICONWARNING | MB_OK);
ipAdd.ClearAddress();
}
}
This is the final version.

got another solution ---
temp.flags = LVFI_STRING;
and everything becomes right.

You are right.

hello,
is it possible to make edit control to take only numeric values and limited digits only ???
i have an edit control which is used for the port number, so i want that the user can enter only numeric value and 5 digits.
any suggestion ??
|
|
|
|
|
Yes, it can.
you can set the property of the control to gain what you want.
I forget the details, but I am sure it can. My computer do not have a compiler, so I can't take a test.
|
|
|
|
|
If your compiler is VS200X, you can right click the control, and click the "Add Variable" in the pop menus.
Then it will pop out a window, and you can set the property in it.
If your compiler is VC++6.0, select the control, and in the "View->Class Wizzard->Add Member", I hope I don't misremember.
|
|
|
|
|
i have vs2008.
i set the limit by using this code ---
portID.SetLimitText(5);
only numeric problem is left.

In addition to the above comment, you can use the FindItem() function of list control directly. No need to loop.
|
|
|
|
|
|
LVFINDINFO temp;
CString ff;
temp.flags = LVFI_STRING | LVFI_PARTIAL;
CStdioFile fileh;
fileh.Open(L"C:\\srvc.txt", CFile::modeRead);
int i;
do
{
if(fileh.ReadString(ff)== NULL)
{
break;
}
temp.psz = ff.GetBuffer();
i = m_objListCtrl.FindItem(&temp);
if(lstrcmp(m_objListCtrl.GetItemText(i, 0), temp.psz) == 0)
{
m_objListCtrl.SetCheck(i, TRUE);
}
}
while(ff.GetBuffer() != NULL);
fileh.Close();
This can work in my computer, but I don't guarantee it could work in your computer.
And by the way, I am in school now, but tomorrow I'll back home(There is no computer in my house ). It means I could not use computer for a long time. And I can't solve problem together with you, I'm sorry for that..

I Now wish to extend my existing XP Program suiteto enable installation into Vista. I do not use Windows Installer, and do not propose to use it. What steps are required to adapt my own installation program, on the basis that neither is registered anywhere.

you need to check dependency of your program

Hi All:
I'm sure there are a number of you who have gone through this experience in the past, and rather than reinvent a method, I thought I'd ask first. Has anyone converted a large number of static libraries to DLLs using an automated method (or semi-automated)? Is there any advice you would give someone trying to do this for the first time? We have about 20 or so to convert, and ideally we would like to find a method that also allows us to use the conversion information to make *nix dynamic objects as well (but it not a hard requirement).
Regards,
-B

Yes (well, about 8)
Ben Burnett wrote: using an automated method (or semi-automated)?
Ummm - I created a new solution, with new DLL projects, copied the code across, hacked it around to add the necessary DLL exporting terms and rebuilt. It pretty much worked, IIRC.
Don't forget to use a a DLL based C runtime model across everyhting if you pass around ownership of dynamically allocated objects.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Also, I always use a macro to define the export type of classes and functions so that they can be used in both static and dynamic libraries easily.

I have a MFC MDI app in C++ and I'm rotating a CImage 90 deg., but trying to handle non-square images. I copy the CImage to a temp. buffer, detroy the CImage, create a new one with the new dimensions and write the pixels back into the new CImage. The problem is the display still is sized for the old image. I think I need to delete the DC and start a new one, but I'm not sure how. Any help would be appreciated. Thanks.

could you give a code snippet?

Here's some code...
if (nx != ny) {
nx2 = ny;
ny2 = nx;
m_image.ReleaseDC();
m_image.Destroy();
if (!m_image.Create(nx2, -(int)ny2, 32, 0)) {
fMessageBox("Error - CImagrDoc::Rotate()",
MB_ICONERROR, "Failed bitmap .Create()");
return;
}
p = (int *) m_image.GetBits();
}

I'll guess the next thing you do is changing the bits in the buffer P...
I'm not into C++ but with the following GDI-functions you maybe get the idea. I'll expect you have a handle to the source bitmap and a DC to the screen. Then use CreatecompatibleDC() to create an extra DC. Use CreatecompatibleBitmap() with the desired dimensions as the target bitmap. Now do everything you want with this bitmap and finally BitBlt() it back to the screen. Below a code snippet (not in C++, but i'll bet you can read it) that mirrors a area of the screen horizontally, to give you some idea:
hMemDC2:=CreateCompatibleDC(hdc)
dh:=int(h/2)+1
hbitmap2:=CreatecompatibleBitmap(hmemdc,w,dh)
hold2:=SelectObject(hMemDC2,hBitmap2)
stretchblt(hmemDC2,0,0,w,dh,hDC,x,y+h,w,-(dh+1),SRCCOPY)
bitblt(hDC,x,y-1,w,dh,hmemDC2,0,0,SRCCOPY)
DeleteObject(SelectObject(hMemDC2,hold2))
DeleteDC(hMemDC2)
Helps this?
