Hi
I've developed a service application using the class of P.J. Naughter which was a good base class for our application. Although everything works fine, I am now encountering some problems related to the security policy of the user where the services. I can't access any network path or resource (like printer). A solution could be to run the server with the NETWORK SERVICE account. But then the application fails altogether.
Does anyone has encountered any similar problems, or knows of a solution.
Are there any good books to write a Windows Service in C++, or even detailed books about services. Right about now any help would be very welcome.

You either have to run the service under a user account that has network access rights, or use the LogonUser, ImpersonateLoggedOnUser and RevertToSelf functions in your code.
onwards and upwards...

Thanks,
I user the LogonUser, ImpersonateLoggedOnUser and RevertToSelf functions
and that was exactly what I needed

I tried passing a CString variable (known to contain text) to a function, and inside the called function, the parameter I passed in is empty. Did something fundamental in CString change? Is there a compiler bug? Am I suddenly incapable of writing even the most simple code?

void ThisFunction()
{
CString myString = "test";
MyFunction(myString);
}
void MyFunction(CString sVal)
{
if (sVal.IsEmpty())
{
AfxMessageBox("Empy String");
}
else
{
AfxMessageBox(sVal);
}
}
In the example above,m I get the message "Empty String".
Like I said, simple code - unexpected result.

and forcing the string to display in a message box (or directly with the debugger), is the string actually empty too? or is it just the .IsEmpty() function which is bugged ?

The string is actually empty (in the debugger) before it gets to the comparison.
The project is an imported VC6 project. This is in a new class that I created using the IDE. I have other classes that were already part of the imported project that work just fine.

A long shot...
Have you tried a "Rebuild All"?

Yeah... 
I can't understand why the code doesn't work.

I presume that's a Unicode build. I've found weird behavior when I use ANSI strings with a CString in Unicode builds. Try making that an Unicode string, so the proper constructor gets called. Non-Unicode string constructors are conditionally marked as explicit when it's a Unicdoe build. It's a breaking change that is undocumented.

Where do I find out if it's a unicode build? Actually, I think non-unicode would make my life easier...

Sorry John, the issue with explicit constructors I mentioned does not apply to your case.
And anyway, your code is not a Unicode build, since the CString accepted the non-Unicode string (in a Unicode build you'd have been forced to specify an L"..." or use the _T macro)
Also I tested out the following code on my VC++ 2005 and got the correct results.
void MyFunction(CString sVal)
{
if (sVal.IsEmpty())
{
AfxMessageBox("Empty String");
}
else
{
AfxMessageBox(sVal);
}
}
void ThisFunction()
{
CString myString = "test";
MyFunction(myString);
}
That code snippet message boxed "test" as expected. So, my best guess is that something happens before the CString gets to MyFunction.

Nish

I have written some code to change the screen resolution and depth then return them to their original settings. All works fine, but the Windows taskbar moves occasionally to about midscreen. Is there a function which automatically refreshes the taskbar to the bottom of any reresed window? Or a windows function I can use to move the taskbar to the required bottom edge of the visible screen?
Many thanks

Well, after a bit of digging I found the answer myself.
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);
You need to notify the shell of a change and force a refresh. No need to move the taskbar around yourself, Windows realises there has been a change and corrects the taskbar positioning.
All good

how can we calculate the length of sent data, from client side ,at server side.
i am sending data from client side but i am not able to know the accurate length of this data at server side.
Thanks N Regards

If I understand the question properly, you can send a header that contains the length of the packet that is arriving. So when you recieve a packet, you always read a fixed length structure that contain the length of the data arriving, then you can allocate space for the incoming data.
Does that address you question?

how can send haeder i am sending and receiving as follows
rVal=send(sock, text, strlen(text), 0);
rVal=recv(sock,data,strlen(data),0);
but i am sending text but i can not receive accurate length of text. please send me if you have any example code.
and also a another problem is i have to send to multiple cleint so which method i should apply.please reply me ASAP.
thanks

Sorry I do not have example code to send - this is something that I did long ago on a DSP processor.
What you can do is send and recieve twice, something like this:
typedef struct{
int packetId; // if this is appropriate for you needs
int len;
}packet_S;
sendHdr.len = strlen(text);
rVal=send(sock,sendHdr,strlen(packet_S),0);
rVal=send(sock,text,sendHdr.len ,0);
rVal=recv(sock,recvHdr,strlen(packet_S),0);
dataLen = recvHdr.len;
rVal=recv(sock,data,dataLen,0);
As far as the best way to send to multiple clients, I do not know. You might do well to post a separate question in the forum again.
I hope this helps.

Hi all,
I am new to C++ and I want to get the value from a text box merge it with another string and then re-populate the text box. I am using the text box in a windows form.
Here is the code I have tried but doesn't work
string S1;
S1 = this->textBox1->Text;
textBox1->Text = S1 + "Test1";
Thanks
Ben

You would be having some control for the text box.
If not go to class wizard and create it. Let us name it as tb.Now you can access the text box text by calling GetWindowText. Modify the string and use SetWindowText to set the text back to the text box
