Hi i want to know what programs installed on my system, i use MsiEnumProducts and MsiGetProductInfo functions, but not all application what i can see in "Add/Remove Program" i get by this functions.
I need to write a program or script that does a few things with (or to) a server after a Windows install. Among those is adding the server to a domain.
Is there a way to do this programmatically or using a script command?
I have some technical questions. In this function:
string report() const {
if(list.begin() == list.end()){
throw "not good";
}
//do something
}
If I throw the exception what is going on with the program? Will my function terminate or will it run further? If it terminates, what value will it return?
When I type in the foll. code, I get the output as 1073741823.
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector <int> v;
cout<<v.max_size();
return 0;
}
However when I try to resize the vector to 1,000,000,000, by v.resize(1000000000); the program stops executing. How can I enable the program to allocate the required memory, when it seems that it should be able to?
I am using MinGW in Windows 7. I have 2 GB RAM. Should it not be possible?
In case it is not possible, can't I declare it as an array of integers and get away? BUt even that doesn't work.
Another thing is that, suppose I would use a file(which can easily handle so much data ).
How can I let it read and write and the same time.
Using fstream file("file.txt', ios::out | ios::in ); doesn't create a file, in the first place. But supposing the file exists, I am unable to use to do reading and writing simultaneously.
WHat I mean is this :
Let the contents of the file be 111111
Then if I run : -
#include <fstream>
#include <iostream>
using namespace std;
int main()
{
fstream file("file.txt",ios:in|ios::out);
char x;
while( file>>x)
{
file<<'0';
}
return 0;
}
Shouldn't the file's contents now be 101010 ? Read one character and then overwrite the next one with 0 ? Or incase the entire contents were read at once into some buffer, should there not be atleast one 0 in the file ? 1111110 ?
But the contents remain unaltered. Please explain.
Thank you.
I'm writing a program in C# that will save lots of data points and then later make a graph. What is the best way to save these points?
Can I just use a really long array or should I use a text file or excel file or something like that?
When using imageio.imageio.read iget a can't create ImageInput Stream. I have a catch exception around it so the program survives but i was wondering if theres a way to put an if statement round it that checks to see if it falied and then attempt to read it again if it did.
basically asking if there is a test for exceptions?
Just that. I would like some information (links, reference, examples...) to guide me to do that.
I don't even know if it's possible.
My objective is to compile a program in Linux and get a .exe file that I can run under windows.
I have a datatable having 44 rows.
I have converted that to list and want to take the rows from 4th row till the last(i.e. 44th).
I have the below program
IEnumerable<DataRow> lstDr = dt.AsEnumerable().Skip(4).Take(dt.Rows.Count);
But the output is Enumeration yielded no results
I am using c#3.0
Please help.
Hello!
I am currently on a project which has been buggy for a long while, now I suspect, among other things, that there is pointer errors in the code.
The program is written in native C++ using COM and uses out-of-process COM servers.
Can anybody give me some tips as how one would go about finding these errors?
Is there specific things to keep in mind, ways to do it, etc...
I have recorded a macro in Excel, but I want to run this code in Google spreadsheets. I do not know how to program in either code. How do I convert them? I tried an online VB to Javascript converter, but this does not work with VBA.
Is there a way to stop other subs from running while in a separate sub.
for instance say your in the sub
CreateNumber()
and the subs are setup like
CreateNumber()
AddNumber()
DeleteNumber()
Is there a way to be in CreateNumber() and call a function to stop AddNumber from running after creaetNumber() is finished? i just want my program to sit there to wait for an event to happen.
Is there a good resource to get run times for standard API functions? It's somewhat confusing when trying to optimize your program. I know Java isn't made to be particularly speedy but I can't seem to find much info on this at all.
Example Problem:
If I am looking for a certain token in a file is it faster to scan each line using string.contains(...) or to bring in say 100 or so lines putting them to a local string them performing contains on that chunk.

My multithreaded Java program crashes because it runs out of heap space and I don't think it should. Assuming the culprit is unintentional object retention, what's a good free tool to investigate what objects are being unintentionally retained?
My IDE is Eclipse.
I have been in an assumption that multithreading gives a lot of flexibility and power to make efficient programs. But I am wrong. Multithreading is sometimes not desirable as it will create serious impact on the way the actual program behaves.
My question?
I am not sure of when to use and when not to use multithreads in applications.
Please update this thread and give your opinions on multithreading and suggestions on its usage scenarios.
Hello guys
I am a web developer and sometimes I have to do some design myself for my customers but design actually is not my best thing to do. I am looking for a program that can help me getting fast and reliable design ideas but I am not looking for code generator like Artisteer.
Actually design is a hard task and my designs always look ugly and messy.
I have been using this "logic" in C++ and VB with success, but am tied up in Java...
Simply put,
public void DataProviderExample(String user, String pwd, String no_of_links,
String link1, String link2, String link3) {
for (int i=1;i<=no_of_links;i++) {
String link = "link"+i;
System.out.println(link);
}
Now, if the variables link1, link2 and link3 have a value of "X", "Y" and "Z" respectively, upon running this program, I get the following output -
link1
link2
link3
What I want is -
X
Y
Z
Any ideas?
Hi there, I'm having trouble working this out. Basically my program has a standard input, I want to modify this so if the user enters a space it automatically replaces it with a / whilst they're typing. I have no idea how i'd even go about doing this or if it is even possible so I am grateful for any help either way.

{
Console.Write(s+"\n"); // i need to send tihs s file to remote machine

Where do I find the lib files for linking my program when using some Boost libraries?
Decided to try its threading functionality but I am getting
Error 6 fatal error LNK1104: cannot
open file
'libboost_thread-vc90-mt-gd-1_42.lib' InterviewPractice
after I include
Error 6 fatal error LNK1104: cannot
open file
'libboost_thread-vc90-mt-gd-1_42.lib' InterviewPractice
I can't find where to get the .lib files for proper linking on the boost website?
Any tips? :)
I just came back to C++ Builder after 5 or more years away. I seem to remember a nice tool where I could drag its pointer over the GUI of my running application and get lots of info about what was pointed at - handle, size, text, parent, children, etc
IIRC, if the exe include debug info I could also get the actual variable name as used in the source.
Does anyone know what program I am talking about? Thanks
By default certain programs format their output according to the type of the stream they write to. For example, the output of ls and ls > file looks differently. I'd like to know how this is achieved by a program. Additionally, is there a way by which we can trick such programs as if the output stream is a terminal where it actually is a file (especially when they don't have any options that affect output formatting)?
Hi,
I would like to create a program wich communicates between pc and an android mobile connected to USB via tcp/ip. Is this possible? How can I get the IP-address to a connected mobile from PC or the other way around?
Any help appreciated
I am writing a program that will need to measure time in minutes.
To be exact, it will wait 10 minutes, execute some code, wait 2 minutes, execute more code and repeat this 5 times (anyone guess what I'm trying to do?) and I am wondering how to do the breaks.
Thanks in advance!
Oh, and by the way, I'm on Mac.
