The problem that I am having is with regards to compiling the RTF files after I have made changes to them.
All I did was open the AfxCore.rtf file and replace the <<YourApp>> callouts with MyApps Name.
I used Microsoft Word 97 and saved the files back as RTF.
I then opened up Help Workshop and compiled the files.
I got numerous errors and the HLP file was not created.
Anyone else have this problem?

Personally, I have always avoided using Word etc to edit the .rtf files. You will find that editing them in a tool such as notepad or Visual studio (as text) will allow you much better control.
Also this article may be of help if you do follow this route: Simplified AfxCore and AfxPrint.rtf files[^]

I have a function that looks like
Process(string str1 , string str2)<br />
{<br />
string concat ;<br />
concat = str1+":"+str2;<br />
ProcessFurther(concat);<br />
}
str1 and str2 passed are strings but represent numbers. Is there a way i can do a type checking to find if its a valid number .
I am looking for something like isNumber() functionality as i need to make sure that what is passed is surely a valid integer and not a garbage string which might have catastrophic results !
Please advise

you could use strtol() to convert the string to an integer, and then make sure the endptr actually points to the end of the string.
bool IsNumber(std::string str, int base)
{
char *EndPtr = NULL;
const char *Number = str.c_str();
strtol(Number, &EndPtr, base);
return (EndPtr != Number && *EndPtr == NULL);
}

how can i differentiate between a conversion for the string "0" or a failed conversion ?
Engineering is the effort !

The routine I gave you does that.

sorry didnt see this
return (EndPtr != Number && *EndPtr == NULL);
|
|

Alternative approach:
bool isNumber(const char* s)
{
int junk;
return(sscanf(s, "%d", &junk) ==1);
};
|
|
|
|

won't work properly. pass in "21@#$" and your function will return true.

Good point, modify as follows:
bool isNumeric(const char * s)
{
int junk1, junk2;
// Check for a number and check that nothing follows the number
return (sscanf(s, "%d%c", &junk1, &junk2) == 1);
}
Reuse is a wonderful thing.

Hi Everyone!
How can i filter packets and analyse them ? 
I had already searched in Google but the only things i found
was a complete sdk which costs 1900 €. I don't think i need
the sdk to capture packets. Maybe someone of you can write an
article about this topic. I think it is an interesting thema.

Hi,
I want to check from my SDI application if a particular file is opened by the user, and if opened I want to close that file.
How do I do that?
Please advise
|

Basically, I believe there would be two types of approaches to this problem:
1. Hook the file system to send notifications when a file is accessed
2. Hook a system event to give you a notification each time a file is opened.
3. Use the standard file commands to prohibit access
The first method is by far the most troublesome and difficult, but will provide the most accurate, functioning results. You would need a low level access to the NTFS file system and be able to enumerate through currently open files. If the desired file is found in this enumeration, it is closed.
The second method relies on the Windows OS to give you a notification when a file system event occurs. The most effective way to accomplish this would be to use some IFS element. IFS (Installable File System) is part of the Windows DDK and allows you to build file system filter drivers, which can capture different events. FileMon is one example from this type of application.
The final option is the most easiest: when your application is started, you open the file in a non-exclusive mode, which means that all other attempts to access this file while your application has it open will fail. However, this means that only your application can access the file in question, and this approach will cause a system crash if used on critical system files. But for protecting application-specific files, this is the most effective one. For an example, see this article[^]

I have been given a bit of source code which I am trying
to compile!
The code uses the functions
SetupDiGetClassDevs( ... )
SetupDiEnumDeviceInterfaces( ... )
which are in setupapi.lib
Unfortunately I get the error messages
error C2664: 'SetupDiGetClassDevsA' : cannot convert
parameter 1 from 'const struct _GUID *' to 'struct _GUID *'
looking at my .h files I see that param 1 takes a 'struct
_GUID' but in the msdn site it takes 'const struct _GUID'
I am led to believe my sdk is out of date!!
does anyone know where I can find the updates, I have
looked everywhere 
I have already installed SP5
thank everyone and have a goog christmas

Hi
I have the following warning when i link. (I can execute program perfectly though)
Programm1.exp : warning LNK4070: /OUT:PROGRAMM2.EXE directive in .EXP differs from output filename "C:\vss\MyProject\Debug\Programm1.exe"; ignoring directive
Any idea what this means?
Best regards
Jens

Per MSDN:
The filename specified in the NAME or LIBRARY statement when the .EXP file was created differs from the output filename that was either assumed by default or specified with the /OUT option.
A client program that uses the resulting DLL might encounter problems.

Hm, could it be that you export some functions via a .def file?
Then check its first line - it should read as: LIBRARY PROGRAMM1.EXE

Hell,everybody.
This is a problem from me. I install WinPap3.01, then install a packet analysis tool ethereal-0.8.16-capture. Of cource, I reboot the OS which is WinXp. My problem is that the analysis just report the UDP packet, can not report the TCP packet. It's very surprising! I think it is not the problemn of the Etheral, cause the other analysis tool can not work too.
Maybe it's the environment lead to the problem. My pc work on the 100M LAN (also, use ADSL). It is work correctly on the 10M LAN (Tool can report TCP packet). Whether I need set some parameter? How to do it?
Thank you in advanced!

Hi Friends,
I designed a graphical editor which supports Line,Rectangle, bitmap and Text control. Now how to implement z order as text control is window hence any object hidden behind it will be not visible.
Thanks
Z order with Windows and non-windows objects.

im assuming u build up a list of shapes to be drawn every time u update the screen ... then simply add a z-order variable to the shape class (u do have a shape class right?) and draw the objects from highest z-order to lowest (or visa versa) ... the painters algorithm in other words ... then all will be hunky dory
this isnt a good plan for game programming btw but u didnt mention games

But Window is object and Line Rectangles are not window. Hence if you pull window over these objects window will always occupy top position. Hence simply keeping variable will not work.
I am looking to design a application which will help to design a form run time. Any suggestion are welcomed. Is there is open source code on any side?
