I don't uderstand what your problem really is. If you have a .lib file for the library that you want in your project you can just add it to the "Aditional Librarie" under the Include part of the Project Settings. You could do that, or user the #import "xxx.lib" in order to actually make the library *part* of your project.

Dear Mickanu,
Thank you very much for your help. The problem i met was solved. I can include the .h file and input the .lib file into the linker and my project can be compiled.
Thanks for your help.

Hello,
I have a very difficult requirement to implement. I need to Base36 (0-9, A-Z) encode/decode a large number(up to 45 digits)string. For e.g. “7211750854866385693202841128538807157909”. I already have a routine that does this conversion but it doesn’t handle more than 64 bits(__int64). I have been thinking about this but have no clue so far L
Any tips/pointers?
Thanks!

You can use Struct
__gc struct encode
{
__int64 n1;
__int64 n2;
};
|
|
|
|
|
You can use an array of characer variables to store the large number.

I'm trying to interface a DLL parameter with .Net String variable.
How do I convert the .net String type to LPSTR used on DLL parameter ?
Like this:
LPSTR sUser = this->edtUser->ToString();
but this cause the following error :
error C2440: 'initializing' : cannot convert from 'System::String __gc *' to 'LPSTR'

Hi Folks!
For an interface to another application I had to develop a C++ dll implementing a given interface. For testing purposes I had a VB6 emulator to try out my dll.
Everything worked well, but now that the dll is loaded into the real program, a windows message I send to fire an event from a different thread gets lost (i.e. is not received by the window I send it to).
The dll is a mixed mode dll. I'm registering a managed event handler for an event of a managed remoting server and this event handler is called without problems.
In order to signal the event back to the host program I have to transfer it to the original thread the dll was loaded in.
In order to achieve this I create an MFC window in the original thread and send a registered windows message to this window from the event handler.
This does work flawlessly in the test program, but when the dll is loaded into the real host application, the window doesn't receive the message.
Has anyone experienced something similar or can give me any hints on why this could be?
Thanks in advance,
mav

Update:
I was told my dll seems to work when the host application is not being run in the debugger.
I've read Surviving the Release Version[^] and think it could be related to mixing debug and release MFC (since I've delivered my dll as release build), but I'm not sure.
Nevertheless, any help would be greatly appreciated...

Hi everybody
How can an application interact to a Windows Services or transact with it?
Tanks for your help

Hi...
Excuse me!
What is your mean?
|
|
|
|
|
|
Generally, through some form of inter-process communication, although for some simple interactions (start, stop, pause, resume a service) SCP is more than enough.
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

Hi!
Thanks for your help
But What is the "SCP" ?
Please explain more obviously!

I'm basically playing with static libraries, with header files that don't have any cpp files...i.e. all code for all header files in static library is inlined, and vs.net won't compile unless i include a cpp file that calls the header files.
Is this a normal practice with other compilers, or just for vs.net...and if just for vs.net, is their an option to disable that?
|
|
|
|

Right Click your header file ander soluton explorer and chose properties and under general chose don't use precomiled headers.
ps: I know this will work, but i am not 100% exactly where to find this setting, because i use public pc

hi for all
This is a simple question but I have no idea how I can do this:
How can I read all lines from a file and insert a new line in a specific local?
thanks a lot for all

<br />
#include <fstream><br />
std::ifstream ifs("path/to_file");
if (!ifs.is_open())<br />
{
<br />
std::string all_file,line;<br />
while( !ifs.eof() )<br />
{<br />
getline(ifs, line);<br />
all_file += line;<br />
if (line.empty())
continue;<br />
}<br />
after this while exists, you have in all_file, well, all file  ...
then you can insert your stuff in string all_file, close the original file open it with "w" or so (make sure the write poinetr is at the beginning of the file), and then write the modified content, that is all_file.

This is managed c++ forum, so it would be better to post managed code
|
|
|
|
|
to anonymous:
yo dude, according to my knowledges this forum is also related to plain C++ !!!. And beside that, reading all lines from a file, should merely follow the same idea, even in managed C (that is C#, not C++ ), right ?

Hi all
Article "A light-weighted client/server socket class in C++" explains how to make a client/server application, but i am a beginner and want to know if there are tutorials out there that are simple to use and that explains, step by step, how to create the server application and the client application.
The apps should use sockets and be as simple as possible (basically just be able to wait for a request (server) and then send an acknowledgement to the client (just a basic text message). it should really only illustrate the basic phases: 1) idle(server waiting for a connection), (2)connection establishment, (3)data transfer, (4)termination.
I know that you need the ip address as well as well as a port for communication - but that is basically all i know
if there is anyone who can help by writing a basic program (or tutorial), or even refering me to websites (one for beginners, as all the websites i find are a bit advanced and confusing for the novice C++ network programmer), I would most certainly appreciate it.
thank you.

Hey...
Im trying to use a small bit of c++ code but have never done a line of it in my life.
I am looking for some help porting it into something readable. Doesn't have to be another language, I just need an explanation on whats going on.
I would learn some cpp myself but honestly I really don't have the time.
Any help would be greatly appreciated.
Thanks
