    Long ethernet cable

    Hello, You are probably right. The long cable is a category 5; I just checked it is a straight cable. The short one must be a crossed cable, I'll check it this evening. Thank you. W

    Long ethernet cable

    Hi! I want to connect two computers by ethernet, in order to share a DSL internet connection. I am thinking of a peer to peer connection, no hub (for the moment). My computers will be eventually located some distance away, so I bought a 40 meters (130 feet) ethernet cable. I have configured...

    How to print a jpg image? How to convert a jpg to bmp?

    Hi, It's a good question and I'm facing the same problem as you. I'm afraid this is again a partial answer... The problem is that the JPEG format is not a built-in standard in Windows. The conversion cannot be done by the system WIN32 itself. Applications typically use some DLLs which provide...

    Starting Out

    Hi, computer programming is typically the kind of activity that you can learn by yourself. Lot of people in this field are self-taught. Personnally I never had a single lesson on programming at school, and learnt all I know "by doing". These days programming skills are in demand, and...

    A general question...

    Hi, You absolutely need to learn C and C++ (caution, despite similarities, these are different languages). To my opinion knowing C is not a prerequisite to learn C++ (I learnt C++ first). But if you don't have a good knowledge of the general mechanisms of programming, you may find C easier to...

    linking a .lib in a project

    Hi! Thank you very much. I didn't know that trick. In my case, it didn't work but I think it is because my lib file is in fact an import lib, not an object lib (no source code inside). Then it raises the next question: if you have a DLL file, how do you turn it into an +object+ lib? Thanks to...

    linking a .lib in a project

    Hi! This looks like a school case. I am working with Borland C++ 5.02. I have an external lib file and its associated dll version, and a header file declaring all the exported functions. I have a project in which I call a function from the lib. I want this function to be linked statically...

    polem with vector class

    Hi, 3 remarks. Maybe one would help? 1. I think that the STL was included in Borland C++ starting from release 5. Make sure of what BCW you are using and if it includes the STL. 2. By the way, if I remember correctly, STL lies in a "classlib" folder. Please make sure of that. In...

    Multiple files

    Hi, It's hard to catch what may be wrong for sure. Your problem may be due that file 1 includes file 2 and file 2 includes file 1. Kind of round trip. It is most of the time possible to get out of this kind of problem by a careful organisation of declarations and definitions. I don't know if...

    how do you get the graphics functions to work?(look at name)

    Hi! I'm not sure to understand your problem. Why not trying a DC? What I know and tell you in case of, is that when I need to use graphics for Windows under BC++ 5.0 I just create an instance of a TDC class, which has all the graphics capabilities: dot; line; polygon; filling routine...

    How do track the value of a variable in Borland C++

    Hi! With BCW's EDI 5.02 you can inspect variables by going in the Debug -> Inspect Variables or Debug -> Evaluate sub-menus. By the way, in reference to your previous thread (how to pass cmd-line args) I checked that you can do this from the EDI, Options -> Environment -> Debugger sub-menu...

    how to pass command line arguments??

    Hi! you declare your entry point in the usual fashion: int main (int argc, char **argv) for console apps; int OwlMain (int argc, char **argv) if you use the OWL framework; etc... You can transmit the argument from the DOS command line, the same way you do from UNIX terminal; Or you can also...

    need a bit of explanation here

    Hi! Well, this is a long mail. I took the trouble of elaborating a long answer to your interesting question. Hope it helps! The concept of pointers comes from the machine language, where variables are handled as memory locations ("address").The same concept has been imported...

    Re: C++ text editor

    Hello, I think you can find such a simple editor among the numerous examples provided with Borland C++ 4.5 or 5.0 (I don't know about previous versions). I can't remember which one right now, but I've seen it, with the complete source code, and the usual fonctionalities: new, save, save as...

    Rose model of Borland's OWL

    Hi everybody! Does anybody know about any Rose UML model of Borland's OWL? Combining both Rational Rose and OWL would be very powerful. Thanks in advance Woliwol PS I'm not yet registered in this Forum, and thus did not vote yet, but I am 100% happy working with Borland C++ v5.02.

    Pointers?

    One example: passing large sized parameters to a function. Suppose you have defined a class TMyClass{ ... } with a big number of attributes inside. Each instance (object) of this class takes up a large place in memory (let's say 60 bytes). Now you want to design a function of prototype...
