here is my code btw:
SecurityTokenServiceClient *client = new SecurityTokenServiceClient(new Uri("https://bglinkt1.bgc.se/BGC.BankgiroLink.WebService/CustomSecurityContextTokenHandler.ashx"));
RequestSecurityToken *rst = new RequestSecurityToken("http://schemas.xmlsoap.org/ws/2004/04/security/sc/sct");
rst->RequestTypeUri = "http://schemas.xmlsoap.org/ws/2004/04/security/trust/Issue";
RequestSecurityTokenResponse *response;
response = client->IssueSecurityToken(rst);
return response;

Hi,
I have dll which is loaded using LoadLibrary and freed using FreeLibrary. The functionality of dll is to send a https request to a server and get the response. I am using wininet library for sending and receiving http data.
my sequence of wininet api functions are
InternetOpen
InternetConnect
HttpOpenRequest
HttpSendRequest
InternetReadFile
I closed all the handles corresponding to above.
any suggestions.
thanks

We can't comment on any custom dll without seeing actually, what is coding has been done in that particular dll!

Hi alok,
Ya i know it is difficult to suggest without seeing the code. I have tried to debug the dll in all possible ways and i found that if i do not send the request i dll is freed normally, but if i use the wininet api for sending the requests and getting response it is taking much time to free the library. i mean to ask wininet.lib internally takes much time to get freed.
thanks

WinInet api are very heavy!.. might be its closing net/Socket connection that might be taking time to unload!

hi,
so is there some way to trace them, which is taking time to unload.

i have a problem on merging 2 lists with 5 inputs on each list. the five inputs were already sorted and i'm trying to have a function to merge it. this is my defining function:
void merge(numA[],numB[],numAB[])
{
}
how can i merge the inputs in numA[] and numB[] and put them in the array of numAB[]?
|
|

|

Those are arrays, not lists. If you used std::list, or std::vector, you could merge them trivially. As it stands, you need to return numAB, create it to be the size you need, and write two loops ( or two memcpy statements would be more efficient ) to copy them where you want them.

I believe you should read about Merge Sort![^]

Try this:
---------
#include <algorithm>
#include <iostream>
#include <iterator>
void Merge(const int (&a)[5], const int (&b)[5], int (&ab)[10])
{
std::merge(a, a+5, b, b+5, ab);
}
int main(int argc, char* argv[])
{
int a[] = {1, 3, 5, 7, 9};
int b[] = {2, 4, 6, 8, 9};
int c[10];
Merge(a, b, c);
std::copy(c, c+10, std::ostream_iterator<int>(std::cout, " "));
std::cout << std::endl;
return 0;
}

I have a program that works just fine if I run it in Debug mode and set up a break point at a specific line. If i run it normaly it doesn't work, Beacuse it skips to fast that part of the program. Now here i am asking you, how can i stop the execution for let me say 3 seconds? Thanks
|
|

|

You can stop the program, but really you need to fix your design. Why is it 'too fast' ? You've not described what it does. If you want to stop for the user to read something, don't select an arbitrary time, show it in a message box that they can close whenever they want.

The program reads a string from the COM port and then enters it in a database. Because the system reads the port to fast and then tryes to enter the string to the database, i only get the first char of the string in the database.

hows your program read string from COM port... as you can read only a byte at time from comport!

Then you need to come up with a way to know that all the string has come through - is it null terminated ?

Ok I'm using a code posted on this side under C++ serial class, I read from the port 16 bytes and i want to write them in the database, i got the string into the database but i seem to get some nasty results too. I should get smth like "FFFF00000000028C" but there are times when i get " FFF00000000028".

I think you could get more help if you were questioning your design instead of asking for a direct solution.
Anyway, concerning your original question, you can make a program slower by calling ::Sleep(milliseconds). If you wait for 10ms or 20ms you can check the port again to see if you received more data. To wait 3 seconds you would call ::Sleep(3000).
Under Windows 95/98/Me the smallest time that actually has a wait effect is 50ms, on NT/2K/XP you can use 10ms as the smallest wait time.
Anyway, it seems to me that a good design would be better than using ::Sleep() to solve a timing problem.
I hope this helps,

hi ,
Here is one trouble I met in my MDI program.
Worker thread is responsible for data collection from other source continuously. I defined one variable varData to contain the coming data. And notice main thread by customized message.
Main thread (CMainFrame/Views) is responsible to update the views to reflect the new value of varData.
I have used one critical section to control the writing to varData in worker thread. Yes. I have to do it. Here my concern is that whether it is necessary/must for me to use same critical section in views of MDI to control reading varData.
in My MDI, so many views are open, if CS is used ,I'm afraid the performance of my prgram will regress greatly.
pls Experts give your suggestion.
Appreciate for your help!

Yes it is. The CS will mean that only one thread can use the resource guarded by it. However, if the data structure is anything but an atomic data type there is the possibility of reading an incomplete (ie corrupt) update.
One way many applications avoid this is by having a queue of allocated changes. The writer gets the CS, allocs a change item, and appends to the queue, releases the CS, then signals a reader (shouldn't normally be more than one).
Reader gets the CS, pulls the queued item, and releases the CS. Uses the queued item to update a snapshot of the data, and deallocs the item. It then calls updateallviews (in MFC apps)
In your design, you are ensuring that the writing of data is serialised; in most cases, reading needs to be the same. I have seen a number of instances where all iterating over a collection needed to be guarded by a sync object as did all writes/erases; the original developer didn't understand that the collection was not thread safe in the sense that modifying while reading was a bad thing to do.
