thanks for replying can you please elaborate a little more?i made these changes in the code but still its taking hard coded path value to open photo viewer from C drive.there's a possibility that client's os might not be on drive C then this code will break.

}
return bRet;

}

}

what if i only want to open the picture doesn't matter if its open in photoviewer or not .but i want to load pic only from resources and not from client pc

DWORD dwResult = GetLogicalDriveStrings(MAX_PATH, text); // text = szLogicalDrives
on this line i am getting cannot convert from wchar_t* to LPSTR

UINT nDriveType = GetDriveType(szSingleDrive);
on this line i am getting cannot convert WCHAR to LPCSTR

so is there any solution?you should ave posted it in comment and not solution because its not
no offense

its not even going inside the loop i think regex is incorrect btw thanks for trying

istringstream is3(result);
const string Pattern = "Address:";

//result is the variable in which i wil get above output
// string line;

// const size_t Len = Pattern.length();
string ipchk;
// string line98;

while (getline(is3, line98))
{
if (line98.find(Pattern) != string::npos)
{

line98.erase(0, 39);
ipchk = line98.erase(line98.size() - 1);

//ipchk = line98.substr(Len);
// return line98.substr(Len);
Ipv4 = ipchk;
break;
}
}
IpAddress=Ipv4;

this

i am storing complete file path of the file i am uploading in the uploaded.txt so all it has to do is that to check next time before uploading by matching the path from totalfiles.txt with uploaded.txt if it finds it in uploaded.txt then leave it and not upload otherwise upload it

this is asn eg

totalfiles.txt have following files:-

C:\Program Files\Android\Android Studio\bin\lldb\lib\plat-irix5\readcd.doc
C:\Program Files\Android\Android Studio\bin\lldb\lib\plat-irix6\readcd.doc
C:\Program Files\JetBrains\PyCharm Community Edition 2019.2.3\help\ReferenceCard.pdf
C:\Program Files\JetBrains\PyCharm Community Edition 2019.2.3\help\ReferenceCardForMac.pdf
C:\Program Files\NetBeans 8.0.2\nb\shortcuts_mac.pdf

uploadedFiles.txt have following files:-

C:\Program Files\Android\Android Studio\bin\lldb\lib\plat-irix6\readcd.doc
C:\Program Files\JetBrains\PyCharm Community Edition 2019.2.3\help\ReferenceCard.pdf

Now all it has to do before uploading is to check if any of the lines are already present in uploadedfiles.txt then dont upload otherwise upload

okay thanks i was just afraid that it would stay in memory like a daemon until a restart

does this include a main that got broken and its exception was not handled by the programmer i.e he didn't use any try catch to catch a possible exception?

i have got another question what happens if there was some error or exception in main()which caused not to reach till the end of main and exited with exception what happens to the thread then because thread stop is dependent on the bool value which is just above return 0.
what if never reaches that bool value?will it run forever until a pc restarts?

no you didn't get my point just before your solution i have posted mine above and in that i am no more using recursion

thanks!can you please point out which approach is better your's or mine and why?
your code is quiet large and a little bit of difficult then mine but i am sure your's must be better as i am a beginner

i know but there's something inside that function which i need to run after set interval of time lets say 5 minutes
i need this function to call itself again and again after 5minutes thats why i have dedicated a separate thread for it because i want it to run seprately from the other sequential code in my main()
i need this thread to stop and concurrently this function from executing too as soon as all the other sequential code is finished executing in the main and in main i am on return 0

i was able to accomplish this with the following code

CURL *curl;
CURLcode res;

curl_httppost* post = NULL;
curl_httppost* last = NULL;
/*HttpPost* post = NULL;
HttpPost* last = NULL;*/

curl = curl_easy_init();
if (curl)
{
curl_formadd(&post, &last,
CURLFORM_COPYNAME, "name2",
CURLFORM_COPYCONTENTS, "CV",
CURLFORM_END);
curl_formadd(&post, &last,
CURLFORM_COPYNAME, "file2",
CURLFORM_FILE, "E:\\BIMS Uni\\CV.docx",
CURLFORM_END);



curl_easy_setopt(curl, CURLOPT_URL, "http://localhost:8081/PCInfo/test.php");
curl_easy_setopt(curl, CURLOPT_HTTPPOST, post);

res = curl_easy_perform(curl);
if (res)
{
return 0;
}

curl_formfree(post);
}
else
{
return 0;
}

curl_easy_cleanup(curl);
But now my issue is that i want to upload multiple files i have directory paths of these files and i want them to upload to the server automatically with some kind of loop and also in above method i am unable to extract filename and i am supplying the file name via hardcoding which i don't want to use

yes i read about it but if we consider speed then vector is considerably better

reason?

got it working with using vector now searching time is increased significantly is there any better approach that would minimize the time search?

yes i changed it to a normal function and now its working perfectly i just had to change it from thread to a normal function thanks for helping i can't check your code but i a pretty sure it would work just fine

i m using the exact above code i think you haven't seen all the code and haven't copile otherwise you would have known...

argument of type "PCTSTR" is incompatible with parameter of type "LPVOID"

when i pass from from ext_search to rd_cb then the second param in rd_cb is not getting what was passed as extension from ext_search you can now paste whole code and just call the ext_search from main and you can see that in debug what i am talking about

i have posted complete code now in which RecursiveDirectory func is defined

that doesn't work either here's the complete code

Code moved to question.

i am able to terate through all extnsions with this code:
void ext_search(TCHAR *root_dir, PCTSTR *exts)
{
while (*exts != NULL)
{
// process next extension
RecursiveDirectory(root_dir, rd_cb, (VOID *)exts);

*exts++;
}
}

void example_func(void)
{

PCTSTR exts[] = { TEXT(".txt") ,TEXT(".docx") ,TEXT(".doc"),NULL }; /* null terminated array */
ext_search(TEXT("C:"), exts);
}
but issue is that its passing some garbage type value to the next function so its unable to match the extension below is the code for matching extension
BOOL WINAPI rd_cb(TCHAR *file_path, VOID *param)
{

TCHAR *exts;
exts = (TCHAR*)param;
//exts = param;

while (*exts) {
TCHAR *cur_ext;
cur_ext = PathFindExtension(file_path);
if (cur_ext) {
if (_tcscmp(cur_ext, exts) == 0) {
/* do what you want here with the file */
/* printf as an example here */
// _tprintf(TEXT("%s\n"), file_path);
//file << quoted(chk);
file << (TEXT("\n"))<

i just checked by replacing it with PTSTR but due to some limitations i can only use tchar so i need to do put some loop here to iterate through all of the extensions one by one and call the recursivedirectory()function with each extension one by one

can you show how to do that?or can't i use loop to iterate through all extensions one by one?

i actually did tht but the problem is i am passing it to a funton and it aonly takes .txt extension and doesnt check other extensions here's sample of my func in which i am passing this
void ext_search(TCHAR *root_dir, TCHAR *exts)
{
RecursiveDirectory(root_dir, rd_cb, (void *)exts);
}

ohh sorry my mistak yes it ws TCHAR i changed to CHAR whie trying to remove error

yes i didn't know about istringstream thanks again (Y)

i cannot use api because it uses libraries like iphlpapi and that have some dependencies that i don't want anyways thanks

i cannot use api because it uses libraries like iphlpapi and that have some dependencies that i don't want anyways thanks

thanks this worked actually i didn't know how to use istringstream and use it to find a substring in a string variable so thanks alot

i can't use popen as it opens cmd which i dont want to show not even for a split second

its returning nothing because you have used cin while all the data i posted above that i got from ipconfig is inside a string variable named output well name doesn't matter

or any ipv4 address which occurs first doesnt matter if its for wired or wireless
i want to get the ipv4 address that appears first

i have mentioned Ipv4 address th first one under wireless adapter lan wifi

i have attached the string output now can you help me figure it out how to get ipv4address only?

thanks K5054 actually i did exactly the same thing you have posted but my issue is still there that it still shos console window for a split second and i don't want to show th console at all

(an empty project for creating a local application)this is what i chose when i created the project and in linker subsytem it doesnt have windows or console it says(NotSet) sorry but i think i can't explain any more then this

then why are you trying to answer if you can't help simply ignore

is an empty project local application

its an empty project local application

its an empty project local application

as you can see i am displaying mac address after converting it in hex and i want to use the same format in which its being displayed through for loop mechanism i want to store it in string variable so next time i can simply print string variable on the screen

no but thanks for trying

so if i add uuid along with mac address still it doesnt make it unique?if yes then kindly tell the solution also instead of just telling that all the mentioned things aren't unique and cant be used collectively to identify a pc uniquely

i think you should mention the laterntive if you think all of the above things cn't be unique and easily spoofed and altred then give the solution
i have said i want to make a signature including all the above things which somehow ill be unique thats why i didnt say just ip4 or mac or pc name i said i'll be using all of this
i was unable to find cpu_id of the pc with c++ code otherwise that would have been included too

just read it
it has many things but not processor or cpu_id that i am looking for

read this already its of no use as it just tells if the cpu is genuine intel or not and thats of no use

can we do this with cli?what i am able to do this to simply create a text file and write date into it and when exe runs again it will check for this file if it exist it will show that date otherwise it will create new txt file and store date in it and display it
but what if the user deletes txt file or he runs exe from another folder
so i am looking for some method thts embedded in exe file in it self

so i am looking for some method thts embedded in exe file in it self

i don't have any settings file how to make that any help?
and do you mean i should create a file when first time an exe is run and then next time if ran i should use simple if to check whether the file that was supposed to be created first time has any data inside of it or not?and if there's any data then it should return date stored in that file(yes i will store date in that file) and if not it means exe is ran for first time and it will store the date in the file and show current date time to the user?
but i don't think thats a nice way..what if user accidentally deletes that text file?
isn't there any way by which it doesnt create an extra file?

i think i entioned i need to use linq query to do that
i know there are alot of other ways to do the thing which i wat but i don't want to do that
i want above sql query in linq query so that i can send it to view of my asp.net mvc project

?

there's only 1 entity as its model first mvc project
and in that entities tables are User,Applied_Jobs,Jobs and Files

character replacement would need extra coding..how to use urlEncode to rectify the issue?any eg?

are you saying that i should use % instead of #?if no then kindly type what are you saying for e.g i have a folder named C# now how i should enter it to avoid this error?

is there any way or anything that i should change in the above code to get it working because i need to use # in file and foldernames both so i cannot eliminate this
you said about encoding how should i encode it while uploading?

offcourse i tried it for files and folder without # and that works fine but that's not the solution i have many folders and files which i want to use and have # in their name

i am developing a student portal so no i cannot develop two separate apps for students and teachers.
and other then this i didn't get what do you mean by hard coded paths.
files are on my pc and this a desktop application , both students and teachers will access it via a same pc/desktop.
i want to save files using filestream because its not wise to use sql database to store files in it though we can

logic isn't right of your query its returning incorrect count of both total classes and attended classes as you didn't put where Pre='true' in attended classes query

thanks for your time now it runs but showing 1 in column field of percentage
and 1 thing more the query you wrote is not returning correct count of total classes and attended classes of some students

Msg 8120, Level 16, State 1, Line 3
Column 'Student.S_ID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

getting above error on your query
how to share pics of tables?

thanks but i want to change the color of tick mark only to green when its checked and to red when its unchecked.
not the whole row just the TICK mark to green

there are two actually four tables Student(S_ID(primary key)),Course(C_ID(Primary key)),StudentCourse((S_ID,C_ID(Foreign keys))Bridge table) and attendance table with (S_ID,C_ID(Foreign keys))
what i am doing is displaying data on datagridview by joining tables and slecting S_ID,S_Name,C_ID and Pre_Abs(Attendance table column)columns from all these tables now i want to insert the info present in datagridview to the attendance table when i click on button..i have done this already with simple insert query to attendance table by using datagrdview.rows[i].cell[2] property
i want to know if there,s any better idea to do this so that i can use JOIN instead of using datagridview property with for loop
for now my attendance table is empty while Student,Course,StudentCourse tables are filled with the data
what i want is to display record(S_ID,C_ID) from studentCourse table and (Pre_Abs) from Attendance table and when i submit the attendance i want it to store Pre_abs record against each S_ID,C_ID in the attendance table
i don't think i can explain it any further

insert into Attendance(S_ID,C_ID,Pre_Abs)
select a.Pre_Abs,sc.S_ID,sc.C_ID from Attendance a,StudentCourse sc
join Student s on s.S_ID=sc.S_ID
join Course c on c.C_ID=sc.C_ID
where sc.S_ID=2 and sc.C_ID=2
this is also not working

Still not able to get what i want now i can select only those rows that match in both tables while i want to updte S_ID,C_ID,Date,Pre_Abs from Attendance table then i want to update it with the values that are selected and showed from StudentCourse table in datagridview in c#

insert into Attendance
SELECT
StudentCourse.S_ID,
StudentCourse.C_ID
FROM StudentCourse
left JOIN Student on StudentCourse.S_ID = Student.S_ID
left JOIN Course on StudentCourse.C_ID = Course.C_ID

where StudentCourse.S_ID='2' and StudentCourse.C_ID='2'

this aint working either

Thanks for your kind help

Thanks for the help really appreciate it (Y)

thanks for the help but is there any way i can use it in de vcpp that has minwg32?i have only basic knowlege of classes functions constructor destructor etc...i dont know these terms api etc i have got the concept of what you have said but dont understand how to implement it in dev cpp mingw32 compiler
