Basically I am not getting any idea on how to proceed. could you please suggest any ideas/suggestions on how to approach this.

Thanks.

Thank you. I will try this out

Thank you. I will try this out

I tried and it worked with double quotation also now "@". Thanks a lot.

String^ targetLocation = "@" + "Hello".

Seems strange to me as well. now it is working with "@" . Thanks.

I just copied the code from your snippet and tried and it worked with double quotation also "@". Thanks a lot.

String^ targetLocation = "@" + "Hello".

Seems strange to me as well. now it is working with "@" . Thanks.

I tried as below and it worked with single quote. instead of double quotes in my dev environment.
String^ str1 = "OXF";
String^ str2 = '@'+ str1;

I tried as below and it worked with single quote. instead of double quotes in my dev environment.
String^ str1 = "OXF";
String^ str2 = '@'+ str1;

My problem is , I am not able to concatenate "@" symbol to another C++/CLI string.
Any ideas on how to concatenate "@" to a C++/CLI string (i.e) String^ sample="Hello";

Appreciate your help.

I am getting the below line in the debugger when break-all (pause) the execution. " Cannot evaluate expression because a native frame is on top of the call stack" . some times it is working and sometimes it is NOT working. my code base consists of UnManaged C++ code ,Managed C++ code and C# code.

Actually our application is a WCF service cum client. We need to run one instance of our application which acts as server in one PC and another instance of our application which acts as client in another PC. We can not run client and server on the same PC.Hence debugging is getting difficult.Could you please let me know if there are any other ways that we can debug and find out the problem in this case. Thanks,Sudhakar

I have increased the sendTimeout="00:59:00" to almost 1 hour. still it is hanging and give the above time out error. Could you please let me know how to resolve this or any tips for debugging.? Thanks,Sudhakar

I checked the Event logs in the target PC. it is as follows. can we infer anything from this.

Message : The request channel timed out while waiting for a reply after 00:00:59.9989999. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

Here is my scenario : i am copying the data from dc to new data contract as below. after copying , when i am executing the createsubscriptions method i am getting the above mentioned error. i have given the details of data contract and error in the original question. please refer to that as well.
Method1(SubscriptionDataContracts dc)
{
SubscriptionDataContract subscriptionDataContract = new SubscriptionDataContract();

List<subscriptiontopicinfo> topicsInfo = dc.TopicList;
List<subscriptiontopic> newTopicsList = new List<subscriptiontopic>();
subscriptionDataContract.ExtensionData = dc.ExtensionData;

subscriptionDataContract.UserID = dc.UserID;

for (int i = 0; i < topicsInfo.Count; i++)
{
SubscriptionTopic topic = new SubscriptionTopic();
topic.DBHandle = topicsInfo[i].DBHandle;
topic.Topic = topicsInfo[i].Topic;
topic.Target = topicsInfo[i].Target;
newTopicsList.Add(topic);
}
subscriptionDataContract.TopicList = newTopicsList;

CreateSubscriptions(subscriptionDataContract); //getting teh above mentioned error here
}

Hi ,

I have data contract as follows. It has knownType attribute to most of them. but still i am getting the above mentioned error while passing this data contract to another method. Please let me know where exactly i need to add the knowntype attribute. I am really in confusion in finding out where exaclty is the problem ?

Appreciate your help.

In short , I need to convert the attached C# datacontract to native C++ code.
In the attached C# data contract , i have data types like "List<datacontacts>" and "object" .
I would like to know how we can convert the above data contracts,list of data contracts ,object datatypes to native C++ datatypes like structures etc..

Appreciate your help.

Thanks for your idea.
Currently my requirement is I need to pass a "list of data contracts" and a C# data type "object" to native C++ .
And then I need to convert them from native C++ to Managed C++.

Here we are facing some problems while we are converting C# data types like “object” and “List of datacontracts” from subscription data contract
to Native C++ structures and then converting to Managed C++ data types.

we have infrastructure/idea for converting normal data contract and normal data types like (string,int) to C strutures for converting to Native C++ and then we can Marshall them to Manged C++ as follows.
wsdc->UserID = Marshal::PtrToStringAnsi((IntPtr) (char *) sdc.UserID);

but we do not know how to convert the list of data contracts to C Structures and data type like "object" to native C++ and then to Manged C++.

Please let me know any ideas /suggestions on this.Please take a look at the data contract i attached above with this question.

Thanks,
Sudhakar

But still , in some of our projects ,we are marshalling (converting to Managed )C# data types to C++/CLI as follows:

wsdc->UserID = Marshal::PtrToStringAnsi((IntPtr) (char *) sdc.UserID);

Now i need to do the same for C# data types such as object and List of datacontracts.

Hi ,

Sorry for the confusion. My requirement is: I have a data contract as follows.it has another 2 data contracts inside it. which contains the values as objects,list etc...
Now i need to call a native C++ method from C# and pass this datacontract to the native c++. here my question is how can i manage the the passing of the below data contract to native C++ method .How to handle this datacontract inside C++ ??

I would like to have the method some thing like this:
EXPORT_VOID sendSubscriptions(handle_t binding_h, SubscriptionDataContract dc );


My Datacontract(s)-nested data contracts are as below:

I think i can use struct inside C++ , which is equivalent to data contract in C#.

I have a data contract and it has another data contract inside it as follows. My intention is i need to pass this data contract from C# to a managed C++ application.

I think we can handle datacontract as a structure in managed C++. but what if the data contract contains objects as elements as per below example ? How to handle this scenario ?

in C# application, i have some code like this
SubscriptionDataContract subscriptionData = null;
subscriptionData = new SubscriptionDataContract();

From C# code application , I need to call the below method in Managed C++ (C++/CLI)
in which i want to pass the above data contact.

ClientSideWrapper.ClientInterface iClient = new ClientSideWrapper.ClientInterface();

iClient.sendMessage(handle,subscriptionData);


I need to create a method in Managed C++ (C++/CLI) , so that i can pass that datacontract (details) from C# to Managed C++ code and do the required processing.


But it seems Managed C++ will not take datacontract as parameter , as i am getting the below error:
with this function in Manged C++ .


EXPORT_VOID sendMessage(handle_t binding,DataContracts::NotificationDataContract^ dc);


error C3395: 'sendMessage' : __declspec(dllexport) cannot be applied to a function with the __clrcall calling convention


Please let me know how to handle this scenario.

could you please give me an windows desktop example that uses App.config

I have an extern variable char UniqueID[88] in another .h file . and i can that access in my file.
I am getting the below errors, though i've include the header file where char UniqueID[88] is declared.
InformManager.obj : error LNK2020: unresolved token (0A0003BF) "char * UniqueID" (?UUID@@3PADA)
InformManager.obj : error LNK2001: unresolved external symbol "char * UniqueID" (?UUID@@3PADA)
Debug\InformManager.dll : fatal error LNK1120: 2 unresolved externals

I have a extern variable char UniqueID[88] in another file . and i can access in my file.
so do you want me to try something like this
DataContracts::InformDataContract^ InformDataContract=gcnew DataContracts::InformDataContract();

InformDataContract->UniqueID= Marshal::PtrToStringAnsi((IntPtr) (const char *)UniqueID );

if i do so it is giving the below error .. please advise on this.
error C2440: 'type cast' : cannot convert from 'co
nst char *' to 'System::IntPtr'
No user-defined-conversion operator available that can perform this conv
ersion, or the operator cannot be called.

Thank you

I am able to display & (ampersand) using &

Thanks for the link on mutex. but how singleton is different from Mutex. I mean functionality wise singleton also allows only one instance of the class.

Hi Jochen,

Could you please look into the below and let me know if you have any ideas on that ? I would like to dynamically format the hex string into groups of 4 numbers.I mean based on the length of the value variable in the question i need to format instead of hard coding with shift operator many times.

Appreciate your help.

Thanks for your solution. it seems working on windows fine. but on Linux it is giving the below error with the same above code though i have used unsignd long long as the data type for value .Please let me know if you have any idea/suggetion on this.

error: right shift count >= width of type

And also please let me know how to avoid hard coding of here with shifts. I mean here i used 11 groups of 4 digits by using >> operator. but is there any way that we can dynamically get the format string with different length of value ? and also what could be the max value of a int64 value ? i mean how many max digits can it have ?

Appreciate your help.

Thanks,
Sudhakar

Ok. thanks. btw can't we give extra size. I mean more than size of buffer.

char result[255] = {0};
char formatStr[20] = {0};
unsigned char precision;

precision i am passing as 16

Thank you. my doubts are cleared. appreciate your help.

-Sudhakar

Thanks a Lot for your explanation.

My input is a sequence of hexadecimal digits ( Eg: 0x1234567890ABCDEF), of arbitrary length, (ofcourse i will remove the 0x part before feeding it to algorithm as you suggested)

My aim is to pass the Final Value (hexadecimal char array)
to a method which takes void* as parameter.

Could you please let me know what this piece of code exactly do ?
and why it is taking half of the length ?

Please refer to the code that i already pasted in the starting of this thread.
Please ignore cout statement.

for(unsigned int i = 0; i < strValue.length()/2; ++i )
{
sscanf( strValueHex + 2 * i, "%2x", &temp );
FinalValue[i] = temp;
}

Appreciate your help.

Thanks,
Sudhakar

Thank You

do we need strcasecmp macro here ?? I am just using strtoull.
is it for just example or do we need strcasecmp for strtoull to work ?

Please let me know your suggestions/ideas on this ?

My understanding is I can remove strcasecmp related code in the above macro since i am using strtoull .

Thanks

Any suggestions/ideas on the above questions are Welcome.

Appreciate your Help.

Thanks.
Sudhakar

However, you should feed it with, for instance "12", instead of "0x12".

if I feed it as "0x12" will it give wrong results ?? or should I not pass like that ?
why I am asking is my input comes like that "0x1234567890123456" .

Please let me know your suggestions on this.

Thanks.

How to print the value of every individual byte.?

Thanks. it is working fine after putting it in top.

I used the above code .while compiling on visual studio it is giving the below error

error C3861: 'strtoull': identifier not found

I added #include <stdlib.h> also. Please let me know how to fix this error. Appreciate your help.
Thanks,
Sudhakar

if i type cast the Finalvalue to char* it is printing some symbols ╠↕
i am not sure what are those symbols ? ╠↕
are they equivalnet to "0x12" in hexa ??

I have a method in my code which takes a void* as parameter.

to pass a hexa decimal value it is using the following code.
I am not able to understand why it was written like that. I tried to print
the value (FinalValue) it is printing just a differnt address (hexa decimal) value every time.

Could you please explain me any suggestion/ideas on this below code ?
Will the below code work for big hexa decimal string like "0xFFFFFFFFFFFFFFFF" without any code change ?? I am not able to understand why it is taking half of the length of original string.

Basically i could not understand it's output/intention.
Appreciate your help

code:
void main()
{
//std::string seedStr = "0xFFFFFFFFFFFFFFFF";
std::string strValue = "0x12";
int strValuelen = 0;

unsigned char* FinalValue= new unsigned char[(strValue.length()/2)+1];
memset(FinalValue,0, (strValue.length()/2)+1);

//convert the strValue to hex
char* strValueHex = (char*)strValue.c_str();
int temp;
for(unsigned int i = 0; i < strValue.length()/2; ++i )
{
sscanf( strValueHex + 2 * i, "%2x", &temp );
FinalValue[i] = temp;
}

std::cout << ((void *)FinalValue);

getch();

}

when i use miValue = _strtoui64(strValue.c_str() , NULL, 16); it is compiling and working fine on windows. but on gentoo linux it is giving the below error
error: '_strtoui64' was not declared in this scope

any ideas /suggestions appreciated.

Thank you. It is working as expected after using _strtoui64() method

I am trying the below code in C++. it is returning some other value but i am expecting
0xFFFFFFFFFFFFFFFF. Is there any mistake here ?

If i give 0x0fff ffff ffff fffb it is working as i expected as below 0xFFF FFFF FFFF FFFB" Please let me know any ideas ? thanks.

std::string str = "0xFFFFFFFFFFFFFFFF";

long long val2 = _strtoi64(str.c_str() , NULL, 16);
it is retuning 0x7ffffffffffffff but i am expecting 0xFFFFFFFFFFFFFFFF

Thanks a lot. It is working. You saved my day dear friend. I appreciate your timely help.

-Sudhakar

on Linux it is giving the below error ? any ideas/suggestions appreciated ?

error: format '%llX' expects type 'long long unsigned int', but argument 3 has type 'int'

I did code like this.
int main(){
char result[255] = {0};
char formatStr[20] = {0};

#ifdef _MSC_VER
sprintf(formatStr, "%%0%uI64X", precision);
#else
sprintf(formatStr, "%%0%llX", precision);
#endif

char* output = result;
if (prefix)
{
sprintf(output, "0x");
output += 2;
}

sprintf(output, formatStr, val);
puts(result);
}

Thanks a lot. Awesome explanation. most of my doubts are cleared.
if you see in my code i am trying to use _snprintf as follows. i've tried to fit the fix given by you as follows. but it seems not working as expected. please let me know if did any mistake here.
if (precision > 0)
_snprintf(precisionMod, sizeof(precisionMod), ".%uI64", precision);

when i use it in my code as follows it is giving the out put as follows

0x1234567A(null)
with the below code
sprintf(formatStr, "%%#%0uI64X", precision);
sprintf(formatStr,"%%%s%s%s",precisionMod, typeMod);
is there any way that we can pad with zeros on left side of the hexa string

Thank you very much. it seems working.
I have one question. How can i use the above in my format. I tried as follows in my code . but it seems not working. Please correct me if I am wrong. Appreciate your help.

_snprintf(precisionMod, sizeof(precisionMod), "%#16I64x", precision);

Yes. i am using VC++ and it supposed to work on Linux as well.
Do I need to do something like this ? I did but it is giving some other symbols.
Please let me know how to use your suggestion in code (it should work on both windows and Linux)

_snprintf(precisionMod, sizeof(precisionMod), ".%'%#I64x'", precision);

the code is here:

#include <stdio.h> /* printf, NULL */
#include <stdlib.h> /* strtoul */
#include<conio.h>
#include<string.h>
#include<stdlib.h>
#include<wchar.h>
#include<iostream>
using namespace std;
int main ()
{
//unsigned long long val = 0x1234567890123456;
unsigned int val = 0x1234567A;

char result[255] = {0};
char formatStr[20] = {0};
char typeMod[2] = {0};
unsigned char precision=16;

sprintf(typeMod, "X");
char precisionMod[4] = {0};

if (precision > 0)
_snprintf(precisionMod, sizeof(precisionMod), ".%u", precision);

sprintf(formatStr, "%%%s%s%s", precisionMod, "", typeMod);

char* output = result;

sprintf(output, "0x");
output += 2;

sprintf(output, formatStr, val);
puts(result);
getch();
return 0;

I am trying to convert an unsigned long long val = 0x1234567890123456; to a string "0x1234567890123456" but i am not aqble to convert it even if i use "%llu" as format specifier with the code provided in code-section
But I am able to convert an unsigned int val = 0x1234567A; to "0x1234567A".
Could you please let me know what i have to do to achieve this ?? Appreciate your help.

I want to convert an unsigned long long val = 0x1234567890123456; to a string "0x1234567890123456" with the below code.

Thanks. it is working. BTW I am using CEGUI library for edit box stuff/GUI . i am looking into how i can do with CEGUI as you suggested solution.
Thanks a lot. I will contact you if i encounter any further issues. Appreciate your Help.

But it is crashing. could you please let me know how i can put the formatted value in a string and while retrieving it i should be able to get it as a normal hexa decimal number so that i can do calculations with that Hexa number.

Appreciate your help.

Thanks,
