I have lot of C++ API exposed in our project and I want to build an application that queries the database and shows some stuff to the user in the UI.
So, essentially, my main code is in the c++ language. What choices do I have over the UI?. I am interested in showing this UI in the form of a html page lilstening to a port.
I am trying to build a web application that uses p/invoke to access a method. Similiar to the one used here - [URL] However I keep getting the following error message - Unable to load DLL 'MyDll.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) I read say to change the output directory to match that of the Mydll directory I have tried that and it still does not work.

View 5 Replies View RelatedI want to make an online application which will connect to my database to do the stuff, but I don't want the credentials to be stored somewhere in the program or in an external file somewhere in the computer or hardcored in anyway in the code.
I think that a good solution is (but I don't know how to implement it): on program execution, the credentials will be downloaded from my website somehow in an encrypted type maybe, from an api or so.
I've not tried before to make an online application, it's the first time. But I do have knowledge of SQL and PHP and I want to try a project like this.
The technology I am going to or can use is:
* Visual C# (in Visual Studio 2010 Ultimate)
* MySQL Connector/NET
* MySQL Database on a shared host
* PHP (if needed)

I had these two queries, I just want both of these will fire on same event. Is any other way to write both queries in single query instead of writing two different queries ....
I am trying to get a list of queries to work right now. I have it so that the user will input 1 of 5 things to compare twin primes in a list. I am just trying to get the queries working fully before actually determining the twin primes that need to be output. The console input will be something like "<= 61" and will display all twin primes from 3 to 61, inclusive.
Well, I thought I had it 100%... Then I realized I have a problem, though. So, I'm reading the string in until a space so I can read in the number after that. So that works fine, but then I also want the "all" and "random" console inputs to work, but they won't unless I put a space after them, which is what I'm trying to avoid...
So, I tried just simply asking for another console input after all of my if statements for the string compare after the first console input. That obviously doesn't work either, though, because it still only wants the first "getline" where it reads until the whitespace.
How to be able to do both on the same console input... The relevant code is posted below:
cout << endl << "What do you want to know about your list of twin primes?" << endl;
string qprompt1;
string qprompt2;
getline(cin, qprompt1, ' ');
string comp1 = ">";
string comp2 = ">=";

I have a CDHtmlDialog app in which am trying to add a CSS media query in the HTML file as shown below, but it doesn't work.
@media (max-width:20em) {
table, thead, tbody, tfoot, th, td, tr { display:block; }
tr + tr { margin-top:1em; }
}
The same CSS works fine if i open in a browser like IE, FireFox, Chrome. But inside the CDHtmlDialog app this doesn't work.

I am having trouble with a program that queries the user for a noun and forms its plural on the basis of these rules:
a. If the noun ends in "y" remove the "y" and add "ies".
b. If the noun ends in "s", "ch", or "sh" add "es".
c. In all other cases, add "s".
I am having trouble getting started.

View 2 Replies View RelatedI want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

How to build the static library on my own using visual C++ 2008.
I used the following code to create the header file and cpp of the library.but I am unable to compile due to the following error.
// MathFuncsLib.h
namespace MathFuncs {
class MyMathFuncs {
public:
// Returns a + b
static double Add(double a, double b);
[Code] .....
Error I get while it is compiled :
Error3error C2653: 'MyMathFuncs' : is not a class or namespace name
class test {
private:
string name="";
public:
event void changedname();
void setname(string value)

i get error about 'a' and 'b' not be a class. but using a template can i validate these code?
my problem is that i don't know how to use objects outside of functions / these is polymorphism, but not accepted by C++
I need to build an array in a function and return that array. Well, two arrays actually, which means I can't return it in the return statement.
Long term, this function/method is supposed to return two populated buffers for further processing. The buffers/arrays are loaded from a file. So, the size of the array is completely unknown until after the file is read. So, you can't have a fixed size array until the function is almost ready to return.
I'm hardcoding the arrays here for testing purposes, but eventually they will be loaded in from a file. That's the whole purpose of this.
Anyway, I need to pass the arrays that are created in this function/method to the caller. But I can't figure out how to do it. The code "almost" works, except that it's overwriting my array when it returns.
Here's the method:
bool GameModelClass::LoadBuffersFromPUNCFile(std::wstring PUNCFileName, VERTEX* &VertexListPointer, unsigned int* &IndexListPointer) {
VERTEX GroundVertexList[4] = {
[Code]....
VertexListPointer returns the correct data structure (actually its an array of structures). The problem is that the first time I use the other variables it over rights the array. The pointer still points to the same spot, but VertexBufferDescription is next to the VertexListPointer and so completely overwrites it.
What I "think" I want is to allocate the array in a totally different area of memory. VertexListPointer should be a pointer, not a contiguous block of memory. It should point to the contiguous block of memory elsewhere.
This is where my weak understanding of pointers comes back to bite me in the posterior end.
In the end, I just want to pass back two arrays/buffers to be used by the calling code.

i want to write a c++ program to build min heap which gets above values from user. remember this program should not alloduplicate values to enter. it should discard duplicate values.
i have four email adresses (for various reasons) and i could probably find a client for all three on source forge, but i thought it would be good practice to use my own. i want to use boost, sdl, and c++, but i cant find a tutorial.

I want to build a dll library with visual c++ 8.0 and got an "unresolved symbol" linker error message when trying to use the library with an application. So I checked the dll library with dependency walker for the exported functions, the needed functions were missing in the library.
I then dumped the corresponding object file with dumpbin.exe, the function was declared as public, like the other exported functions. On the next step, I set the verbose switch for link.exe.
The verbose log told me, that the function was discarded on the linker run. What can lead to that behaviour of the visual c++ linker ?
