Hello All, I have searched every forum and google etc but nothing directed me in right path. Requirement: I am using a COM object which can be initialized only once. But, when I try with webapi the first run goes fine and the rest fails as the COM object does not allow initialization for second time. With the below code, I notice that the new COMClass(); is being triggered everytime there is a GET request. Is there a way I can define the COMClass object to be executed only once and can be re-used by all the GET requests? namespace …

Hi, When I initialise then access the `g_spMyLog` shared pointer, from within the `CSingleton::CreateLog` member function, it works ok. Accessing the SP from the static member function of `CSingleton::Create()` causes an `access violation` in the original project and an abort in this sample project displayed below. In the original project I think the object is going out of scope somewhere but I don't know where. The factory function is created within a DLL as `return (static_cast<void*>(new CMyLog));` which is then `static_cast` to a `CMylog*` straight into a shared_ptr like this: `g_spMyLog.reset(static_cast<CMyLog*>(CreateVoidObj(is_Binary)));` but that's not included here. // File: CSingleton.h #pragma …

Hi All, I want to get all the IPs of the A RECORDS for **mail.google.com**. The aim is to deny access to these IPs. I learnt that mail.google.com has several IPs. I did the following steps: 1. whois google.com 2. I got the following as its DOMAIN SERVERS: ns3.google.com ns2.google.com ns1.google.com ns4.google.com 3.# dig @ns1.google.com a mail.google.com ;; ANSWER SECTION: mail.google.com. 0 IN CNAME googlemail.l.google.com. googlemail.l.google.com. 300 IN A 74.125.233.86 googlemail.l.google.com. 300 IN A 74.125.233.85 I thought this would give me all the IPs. Currently, in an attempt to get the other IPs I am digging 4.2.2.2 & other free …

Hi I was taught not to use global variables and one of my friend is using global variable for database handle for his website... could you please explain if there is an issue if he uses global variable for database handle? he is using it to access database from anywhere in the application.. so he doesn't need to connect to db every time but surely if someone has access to this global variable they can wipe the data in the database... could someone please explain if it is possible for someone(hacker) to access global database handle variable and run queries …

I would like to have a file in my project which contains variables for use by all classes. I this possible to accomplish efficiently. I have heard that using a module with static varibles could work.

I'm having a bit of a problem with how to code something. Here is how it is in my head. I want a function which is not part of a class to access members of that class, so I want to make the class global. I have done this with other classes by the normal method of `extern Class instance;` In a global.h file and `Class Instance;` In a global.cpp file. The problem arises because the class instance needs to be instantiated after other data is made available globally after another non class function has logged into website, and returned …

I'm new to c# programming, and I am a little stuck on how to make a variable available across multiple forms. I read that i should make a public static class, however, my code is as follows: private void btnLogin_Click(object sender, EventArgs e) { accountNo = txtBoxAccntNo.Text; valid = validate(); //uses validate() method to check validity if (valid == true && accountNo == "11111111") { ManagerScreen Manager = new ManagerScreen(); this.Hide(); Manager.Show(); } else if (valid == true) { s customer = new s(); this.Hide(); customer.Show(); } else { if (count == 2) { this.Close(); } count += 1; txtBoxAccntNo.Clear(); …

I have tons of files in this project as I am programming an ARM board. Making a tilt snake game where the snake is controlled by an accelerometer. I am using a timer interupt (handled by timer0.c) to toggle a boolean variable `extern bool toMakeFood;` stored in "includes.h" that tells "main.c" if food should be displayed or not. The problem I am having is that timer0.c throws a "no definition for toMakeFood" error while main.c has no problem. They both have the line #include "include.h" Heres the code although I have ommited irrelevant parts as like I said, this is …

Based off some stuff from my last thread I tried to write a search results page using maximum 3 parameters. I used a couple of function to try and get everything organized. One: sort_mysql_results has no defined parameters so I can put in as many parameters as needed. The code itself doesn't throw any errors but it obviously doesn't work. I tried debugging by adding echo to each function to see what is being executed. I find only one executes. Code: (kinda long, sorry) <?php function get_soundex_query($str,$member) { $ss = sprintf("SELECT *, SOUNDEX('%s') AS src, SOUNDEX(%s) AS src2",$str,$member); $ss = …

My site needs a way to know whether a user is an admin or not in multiple pages. So is it safe to store whether a user is an admin or not in session variable? Or is there a better alternative (Maybe another superglobal variable?), It will only hold a number.

I am new to python and cant figure out what I am doing wrong with the global variables. Here is an example of the problem I am having. number = 0 def test(): global number number = raw_input("Please type a number.") def prints(): global number if number2 != 1: print "Yes" else: print "NO!" test() prints() In this example it prints YES no matter what number I enter. Any suggestions?

I was working on a project when I thought that maybe a ::. operator would look funny in some code. Just for fun I typed that into the global scope area like this: [CODE]::. int main() { //etc...[/CODE] and my code completion software said too many results to display. My question is what results could it be talking about? Is it possible to define global operators?

I am attempting to create a global temp table to be used between two sessions being called from a webservice. When I attempt to access the temp table from the second session it can not be found. The reason I am using a global temp table is because the initial session is created on a before event handler which calls the service and then from an after event handler. I have checked that the table is still available after the initial session closes, and I am still able toe query the data. Any help would be greatly appreciated! [CODE] public …

Hi all, I am hoping that the DaniWeb community might be willing to assist me in my research efforts. I am a researcher based in University College Cork (Ireland) and I am involved in a research study on the subject of software development in global virtual teams. As part of this study I am conducting a questionnaire. Coordination is often reported as being particularly challenging for global virtual teams engaged in software development. This questionnaire seeks to gather data relating to coordination issues in global virtual software development teams. As experienced practitioners in software development, I would very much welcome …
