There's more politics in there than the dying stuff, brother. I have already 'gave them a favor' by playing bullshit to the people who developed me to be a proud countryman. Now you wanna give me to the wolves?

| | You declared you array wrong. > char array[5][**2**] = { "blueone", "greentwo", "redthree", "pinkfour", "yellowfive" }; This declaration says that there are 5 elements that themselves are arrays consisting 2 elements. You can declare them like this: `char (asterisk character) array[] = { "blueone", "greentwo", "redthree", "pinkfour", "yellowfive" };` NOTE: …  |
| | You can't do that in C++. Microsoft Office Applications do not use the ordinary menu we see in other windows-based program. |

| | First of all, I did not see any variable declared with an identifier To and From. But I suppose the main error in this class is your declaration if these variables: m_To, m_From and m_Msg. They are all pointers. And the fact that they are pointers, you should not call … |
 | If your goal is to read the file line by line without the carriage return and line feed (CRLF), you can do so without allocating large amount of memory. And, I still opt the method you choose than using another object for that purpose. Dim strBuffer As String Close #1 … |
 | Typing ULONG instead of ulong might help. BTW, DWORD is the same as ULONG. |
 | First, have a cleanup of your code. You may (must) replace your code from line 40 up to line 62 with the code below. That way, it could be cleaner to read (and debug) your code and it might help us—including yourself—solve your problem. if (reply == 'y') { switch … |
| | Previous answers are correct but I just want to post something clearer. If you are planning to use more than one database simultaneously in your program, you have to make one connection per database. But the most ideal solution here is to make links to the table of interests from … |
 | OK, for the sake of answering the question, when creating your main window (with CreateWindowEx API and not with CreateWindow macro), include in the extended window style the WS_EX_TOOLWINDOW. But you'll have title bar which is awkward for a main window. If you are using a dialog box as your … |
| | But using random numbers in createing bank account number, I suppose, is not a good idea. There are a lot of ways you can generate a unique bank account number. One of this is using the date and time a client registered.  |
| | He he he. Actually, the OP's confusion is valid. After the state `while( count++<=5)`, count's value will already be 2, thus `cout<<count*(count-2)<<" ";` will be 2*(2-2)==>2*(0)==>0. It's like the sum(A1:A5) function in excel returning different result compared to A1+A2+A3+A4+A5. If you're very much sure there's nothing to check in your … |

Yes, that's true, IF, you allocated them using the … |
| | Calling registry functions does not cause GetLastError() to return any error codes. They are rather returned by the registry function you called.

| | You can combine `info.wShowWindow = SW_HIDE` with `info.dwFlags = STARTF_USESHOWWINDOW`. But the GUI app you are trying to run could always ignore the value of wShowWindow of STARTUPINFO structure (which is passed as `int nCmdShow` in the WinMain entry point) and show its own window the way it wants (the …  |
| | Re: typedef struct Why this program crashes not because of *typedef* but because of using an uninitialized variable. Look at your code at line #6: You declared `static test *p` and, without allocating it, used in your `int main()` function.

| | if you just want to check if your process is still alive or dead using the process id (pid) you have, calling the OpenProcess API would suffice. |
| | But, in continuation to deceptikon's reply, if you just want to be able to call ShellExecute while enabling you to pass your sProgramName variable as an argument, you can use its ANSI version without much hassles, e. g. ShellExecuteA(NULL, NULL, &sProgramName[0], NULL, NULL, SW_SHOW); |
| | Using the right shift (>>) operator is the quicker, if not the quickest, method. |
| | As your class declaration says, **buildFromInputString** is part of its structure. But when you defined the functions of your class, particularly buildFromInputString function, I think you simply missed to type something.

 | Well, I think there's no way to **directly** convert hex to octal because a hex value needs to be parsed first to get its value in real numbers (decimal). But the process is always the same: to convert decimal to another notation (hex, octal) you divide the number with your …  |
| | You can use unsigned long long or you can create a class that can handle infinite numerical value (although may not be worth in some particular case).  |
| | All posts above are sufficient answers. I just want to add a little additional info regarding the `protected` statement: Data/properties and methods of a class declared as protected is only accessible to the class and its inheritors. |
 | If you are targetting Windows platform, using a mutex, as suggested by triumphost, is, as my personal experience, the best way to do this.

 | Hello, meLiel! I'll give you an example how to check whether a record exists in database or not. This is best and easily done if your database records has a field that contains a unique key or id. On your sample code, I will just assume that **txtEnterID.Text** holds the … |
| | What kind of error are you receiving, run-time or compile time? May I know the IDE you are using and its version? |
| | If you really have typed line 3 (in reference to nullptr's post) that way, it is sure to generate a compile-time error `cannot convert parameter 1 from 'char' to 'void *'`. But if you have typed it like line 2, I'm pretty sure you will get a 14. |
