[Solved] c# if statement && || [closed]

by

[ad_1] Here is how you can do that (I’m not going to post the actual code because then you wouldn’t learn anything): Check Ping If Ping is OK, reset counter. If not, increment counter. Check when the last time you sent an email was. Send an email if appropriate, don’t if it’s not (e.g. define … Read more

[Solved] Why does this program not output anything? [closed]

by

[ad_1] The ternary ?: operator requires both output operands to either be the same data type, or at least convertible to a common data type. A char* cannot be implicitly converted to an int, but a 0 literal can be implicitly converted to a char*. Try this instead: #include <iostream> int main() { int test … Read more

[Solved] I am working in wcf service i created one function its working fine but i have to reduce line sizes in that function

by

[ad_1] It is difficult to understand your question but I suspect you are trying to return an array that is larger than that allowed by your current transport binding settings. BOTH in your server and client you should look at increasing your readerQuotas eg: <readerQuotas maxDepth=”32″ maxStringContentLength=”10000000″ maxArrayLength=”10000000″ maxBytesPerRead=”10000000″ maxNameTableCharCount=”10000000″ /> and possibly also your … Read more

[Solved] What’s wrong with this code which prints the value at address obtained after converting an integer to an integer pointer [closed]

by

[ad_1] *((int*)2000) is not “perfectly valid code”. The result of converting an integer to a pointer is implementation-defined. It’s likely that in your implementation, (int*)2000 results in an invalid pointer. Trying to dereference an invalid pointer produces undefined behavior, which means that anything can happen. When you ran the program with the printf line uncommented, … Read more

[Solved] How can I set object in list [closed]

by

[ad_1] i want change list[0] by changing f variable (not list[0] directly) That is not possible. The collection list is made up of pointers to objects as are the variables f1, f2, and f each a pointer to an object. By changing the pointer of f you do not automatically change the pointer held in … Read more

[Solved] C# JSON Variable Name reserved [closed]

[ad_1] Nodes is a JArray, not a JObject, so cannot be casted as such. Try this: var json = JsonConvert.DeserializeObject<dynamic>(JsonData); var nodes = ((JArray)json.Nodes).ToObject<string[]>(); [ad_2] solved C# JSON Variable Name reserved [closed]

[Solved] No matching function call for ostringstream `.str()`

by

[ad_1] When you do writeSite(body.str(), “application/json”); the string object returned by body.str() is temporary. And non-constant references can not bind to temporary objects. A simple solution is to make the site argument const just like you have done for the contentType argument (which would otherwise suffer from the same problem). [ad_2] solved No matching function … Read more

[Solved] Environment variable set in batch file cannot be accessed in the C code compiled by the file [closed]

by

[ad_1] Wild-assed guess, because you don’t even show a single line of C code: getenv(TEST_VAR) should be getenv(“TEST_VAR”). PS: To avoid downvotes for your next question (and possibly unhelpful answers like mine), please read http://www.catb.org/esr/faqs/smart-questions.html explaining the art of asking smart questions. 2 [ad_2] solved Environment variable set in batch file cannot be accessed in … Read more

[Solved] C++: Trying to read from a file line by line, saving into a vector and then printing the vector prints nothing

by

[ad_1] You could – after skipping the line count – read in each individual character and compare it to ‘0’ or ‘1’. See the following code: int main() { vector<bool> bits; ifstream f(DATAFILE); if (f.is_open()) { int dummy; f >> dummy; char c; while (f >> c) { if (c == ‘1’) { bits.push_back(true); } … Read more
