C# :: Opening A Second Form Project Within A Project
Jan 22, 2014
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)

I have to do a project for Programming and he said in quotes
"Programming exercise 10.6: the programming project is as described, except do not represent the points using structures.
Assume, as known, the ten (x,y)-values corresponding to x=0.0, 0.1, 0.3, 0.45 ..etc and use y-values from the
function xsin(x); as in (x,y)=(x, xsin(x)) = (0.3, 0.3sin(0.3)).
Use value n+1=10, so the LaGrange polynomial will be order = 9."
What does it mean to not represent the points using structures??

At the moment im trying to integrate an dll in my project (first time).
I copy the lib and dll to my project-directory and the header to my include path.
Now i get a linker error:
1>LINK : fatal error LNK1181: cannot open input file "libWebSvcTx.obj"
the dll calls libWebSvcTx.dll.
I insert the libWebSvcTx.lib to the Dependencies.
Don't know whats the mention of the output and how to avoid it...

I'm pretty much newbie in creating a successful GUI in C++. Although, i managed to create 4 buttons that should show a certain form. Lets say, Form1 is my main form, therefore - Button 1 will open Form2, and Button 2 will open Form3..... But the conditions is - If there is a form that is already open, clicking again on the Button that should open it, will Close it, but all the forms (form1,2,3,4,5) can be enabled together.
Also, a very important note is that whenever i close a form, in any way of closing it (Not the main form) It will "save" the changes i made (Such as ticking checkboxes and so..) and won't reopen it, it will just use "Visible" i guess ?
Notes :
If i use Form2 ^form2show = gcnew Form2;
and then Form2->Show();
I will be able to simply ATTACK the button and open Billions of form2 ^_^
Although, when i use Form2->ShowDialog();
It won't let me open the form3,4,5.
Which isn't so bad, but when i exit from the form2, it won't save my changes (Such as checkboxes..)

I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

I am writing a program that has many header files and their corresponding implementation files. I collected all the header files in a folder and did same for the implementation files into another folder. I'm using the Dev C++ IDE; I could add the files one by one to the project. Instead of doing this however, I tried adding the two folders to the project; but, the project did not compile!! The compiler could not find the files resident in each of the folders!
How I can add the folders to the project so that the internal files are visible to the compiler; or do I have to go the longer route of adding the internal files individually??

I am building a log4net wrapper project where I reference log4net.dll. When calling this code through a static instance to log messages the new project also wants me to reference log4net.dll even though I have a reference to my logging project which in turn has the reference..

Here is the problem:"Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following:
a. Store the number as a positive integer.
b. Convert and store the number as a positive integer.
c. Print the number as a Roman numeral or positive integer as requested by the user.
The integer values of the Roman numerals are:
M 1000
D 500
C 100
L 50
X 10
V 5
I 1
d. Test your program using the following Roman numerals: MCXIV, CCCLIX, MDCLXVI."I'm doing the best I can to understand the concept of the class. Here is what I have (which is not much thus far, and nowhere near correct I'm sure).
#include<iostream>
#include<iomanip>
using namespace std;
class romanType {
public:
void getRoman();

I am currently working on a custom "Array" class for a project, and I have run into an error I don't quite understand the source of. The relevant code is as follows:
template<typename T> class Array {
private:
T errValCopy;
public:
T __errVal__;
uint16 __size__;
T* __ptr__;
Array(const T& errorValue);
[Code] ....
When I try to run the following code:
Array<Array<int>> a(Array<int>(-1));
The error log tells me there is no appropriate default constructor available. If I understand it correctly, "default constructor" refers to the constructor which lets you just write Array<int> a; instead of Array<int> a(...);, but I can't see where in the code such a situation occurs...

If I drop this regular dll project and create a new MFC extension dll project, it will involve too much work. I wonder if there is relatively easier way to convert an existing regular dll project to a MFC extension dll project? BTW, how can I tell a MFC extension dll project from a regular dll project?
