I'm implementing a window in which some parts are valid drop-targets and some arent.
I've read that if I return DROPEFFECT_NONE in OnDragEnter() I won't get any calls to OnDragOver(), so I always send back DROPEFFECT_COPY.
In OnDragOver() i perform my minute-logic and return any of the drop effects, including DROPEFFECT_NONE for which I expect a 'do not do this' icon to appear next to the mouse icon.
This doesn't happen to my regret, whenever I return DROPEFFECT_NONE windows treats it as if I didn't return anything, it keeps the previous cursor.
What am I doing wrong ?
Thank you very much

I have tryed to build a static library which includes a method to show a dialog (defined in a ressource file) The linker warning I get is:
GLAP.res : warning LNK4221: no public symbols found; archive member will be inaccessible
Guess that's why the dialog never shows up when I use the generated lib in in a project.
Does anybody know what's the problem?
Is it possible to build static libs with ressources like dialogs at all?
Thanks! Constantin

You can only have one resource block in an executable. The linker doesn't know how to link two compiled resources (.res files) together.
The way I've done it in the past is to include the library's resource file in the application's resource file. See how afxres.rc is included by the MFC wizard (View > Resource Includes in VC6).

Seems as if that's the only way. Thanks!

Is there an easy way to read a file line-by-line, not using MFC? I looked at fread, ReadFile, and ofstream, but I couldn't find a "ReadLine" function in any of them.
Thanks!

Take a look at ifstream::getline and string::getline.

You can use getline()
#include <fstream.h>
void main()
{
char buffer[256];
ifstream file;
file.open("c:\\autoexec.bat", ios::in | ios::nocreate);
if (file.good())
{
while(file.peek() != EOF)
{
file.getline(buffer,255);
cout << buffer << endl;
}
file.close();
}
else
cout << "error opening autoexec.bat" << endl;
}the default delimiter for getline is \n, see msdn for more details.
Hope this helps

One solution is std::getline().
string sInput;
std::getline(file, sInput);

I recommend Network Programming for Microsoft Windows, Second Edition
by Anthony Jones and Jim Ohmund for winsock programming.
As for SMTP protocal, search FAQs and Google.

Is there any way (In code)from my MFC application to Copy,Paste and rename a file...such as an .exe file?
For example,lets say i have an imaginary .exe file in a folder called "Test".
I want to make a copy of test.exe,rename the copy(not the original)to test1.exe,and place it(or
copy it)to a folder named "Test1".
Is this at all possible?
Appreciate your answers.
Thanks.
