Visual C++ :: How To Refresh Logon Screensaver Parameter Changes
Jan 13, 2014
I have a Windows service that may change the timeout of the logon screensaver in Windows (as described here.) To do that I change the following registry key to the timeout in seconds:
Code:
HKEY_USERS.DEFAULTControl PanelDesktopScreenSaveTimeOut
The issue is that how do I make OS "read" or refresh the actual screensaver timeout after a change in the registry key above?
My practice shows that it is refreshed (for sure) only when I reboot the system, but in my case I need it to be applied without the reboot.

In Form1 I have a Datagridview showing the content of a table from DataBase.
In Form2 I add or modify a row in that table. So, when I get back to Form1 I would want the DataGridView get updated automatically.
To populate the DGV I use a Linq To Sql query:
Code:
Query = From ..... ;
Me.DGV.DataSource = Query;
or
Code:
Query = From ..... ;
Me.BindingSource1.DataSource = Query ;
Me.DGV.DataSource = Me.BindingSource1 ;
I have been trying to use:
BindSource (as DataGridView.DataSource)
BindingSource.ResetBinding(False)
DGV.Refresh()
etc...
Also, I added a new row in the same Fomr1 and nothing happens.

Is there an "easy" way to define a template with a template parameter that could resolve to "nothing".
Code:
template <typename T1, typename T2, typename T3>
struct one_to_three {
public:
T1 t1;
T2 t2;
T3 t3;
};
Now I want to be able to instantiate that in such a way that T3 and T2 (if T3 also) resolve to "nothing".
Don't point me at tuple<>, this has to be a single structure. No dummy's, nothing effectively means nothing.
so on Win32
Code:
one_to_three <int, int, int> x;
sizeof(x) == 12;
one_to_three <int, nothing, nothing> y; // whatever 'nothing' needs to be.
sizeof(y) == 4;
T1 will never be 'nothing'
T2 will only be 'nothing' if T3 also is 'nothing' (if it works with T3 not being nothing, that's fine, but it won't get used that way).
Portability is a non-issue, this only needs to work in VS (2010 and higher). The 'real' solution will need up to T10, I have a solution working with SFINAE, but it takes very very long to compile and it's getting very unwieldy if you would need to add T11.
I know it's not an ideal type approach, but it is what it is, this is a necessity due to linking with a legacy API which we don't have control over.

i have this Stealth Injector source from internet so this program is for injecting .dll to an .exe this program was made by someone to used for cheating in online game but i need to use this program in my private server game online to tell the game client .exe the server IP, that is stored in a dll file.. the problem is i don't want the player to directly execute this program, but they need to run the game patcher first to do the patch.. so i need to put some secret parameter argument that will block player from direct execute..
i know nothing about c++ i only know that you need to use main(int argc, char *argv[]) i've try to put something like this
Code:
int main(int argc, char* argv[]){
stringstream sparam;
string param;
[Code].....
the code works fine but the rest of code won't executed..
i've attached the cpp and header files for you guys to check source.rar

I need to pass a variable to a dialog box.
Code:
Doc* pDoc;
Dialog dlg;
int input = dlg.DoModal();
When I call dlg.DoModal() I need to somehow pass the pDoc into the dialog box. Everything I need the variable for is taking place inside the oninitdialog function. Is there anyway to pass the variable to that function?

So I'm currently using Visual Studio 2013, and I was left for homework as a beginner programmer to calculate two summations. First the summation of k to n. k=1 and the equation being k^3. The parameter would be n and I need to printf the results for n=5, 33, 100, 442, 3456.
I know that some of the numbers are big values so float or long should be used but how to define these as of yet.
Another is to find the summation
(n)
(k) <<-- one big paranthesis
for values k=8 and n=10, 21, 35, 46, 68
How to start excluding <stdio.h> and int main ... Also, do I have to repeat a new function for every number for n?!
This is what I have so far for something I did differently
// Factoriales Sumatorias
#include <stdio.h>
int suma1 {
int n = 5; // Defino e Inicializo la variable
long sumatoria = 1; // definicion e inicializacion del resultado
while (n <= 5)

I have a datagrid, which has a column called Status. In the database, the field is a text field that can have the values up, down, or danger.
I needed to display the status as a "light" as per client request, so I have a StatusToImageConverter class that receives the status, and returns the proper image to display in the datagrid column. Works fine.
Now the issue I am having... I have a combo box above the datagrid for the user to filter the results if desired. The filtering works fine, but the newly displayed devices do not have their status light. In the Status column, nothing appears after the user filters. I think it may have to do with the fact that I am not re-initializing the datagrid, but just refreshing it? That's just my educated guess.
XAML:
In the UserControl Resources:
<local:StatusToImageConverter x:Key="ImageConverter" />
In the DataGrid Control:
<DataGridTemplateColumn Header="Status" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>

I Cant get my checkers game board to refresh every time i make a move. i have system("cls") But it does nothing of the sort.. To move a pice ive created an illusion which swaps one pieces appearance with another :
void getpiecetomove(int startx,int starty, int endx, int endy) {
boardpiece tmp;
//Regular Moves Pieces
tmp = board[startx][starty];
board[startx][starty] = board[startx+1][starty+1];
board[startx+1][starty+1] = tmp;
system("cls");

class CMyclass
{
public:
CMyClass(BOOL bUseWhichMemManager);
void* operator new(size_t);
void operator delete(void*);
};
I create two memory manager called CMemManager1 and CMemMangaer2, using different algorithms to allocate buffer. Now I want to control which memory manager to be used, when calling new.
I try to add a parameter bUseWhichMemManager to the constructor, but in overrided new function, there are no way to access the parameter. Is there a way to pass more parameters to new operator, such as:
void* operator new(size_t size, BOOL bUseWhichManager);

I would like to know how to make Lynx follow meta refresh links automatically, At the moment it just provides a "clickable" link you can accept the refresh. I would like this to be automatic.
--- Initial problem ---
We have a DB Backup script written in PHP/HTML and uses the page refresh to loop the backup (every 2 minutes). Using a full fledged browser is not really an option on our machine as the resources are very tight. So we tried Lynx and it has the perfect footprint but the only problem is it doesn't refresh the page.
I'm thinking I just need some way to force Lynx to reload the page after the time has elapsed. Maybe create a new function that starts a timer and hold the url until the timer ends then force Lynx to visit that url. Im a PHP Procedural kinda guy and I cant think how to set this timer event safely without corrupting or crashing the program or creating memory leaks.
(source code im using: [URL])
This is the function that handles meta refresh.
Code: /*
* Given a refresh-URL content string, parses the delay time and the URL
* string. Ignore the remainder of the content.
*/
void LYParseRefreshURL(char *content,
char **p_seconds,
char **p_address)

My errors are at the end of the program in two function calls within the definition of the InsertByValue function. g++ does not seem to recognize NumArray as a valid parameter.
#include <iostream>
#include <assert.h>
using namespace std;
const int CAPACITY = 20;
/* Displays the content of an int array, both the array and the size of array will be passed as parameters to the function
@param array: gives the array to be displayed
@param array_size: gives the number of elements in the array */

Can local variable be passed as the parameter for a new created thread procedure? Here is the example code:
Code:
void CDLG::some_function()
{
CString strFileName="abc.doc";
//local variable, can it be valid for being passed into the following new thread???
//Can strFileName still be accessed from within the stack of thread procedure?
::AfxBeginThread(ProcessContentThread,(LPVOID)&strFileName);
}
[Code]...
There is another method using variable on the heap,
Code:
void CDLG::some_function()
{
CString strFileName="abc.doc";
CString* pstrFN=new CString(strFileName);
::AfxBeginThread(ProcessContentThread,(LPVOID)pstrFN);
}
[Code]...
I test these code, both methods work as expected, but I doubt whether the first method is a good way. OR if only the second method is the correct way to pass a parameter to a thread.

Here's my function definition
bool validateNumber(string& text, int min = 0, int max = -1, bool useMin = true,
bool getValid = true)
The code takes the string text, and checks the make sure that the input is valid and safe to convert and use as a number. However, sometimes there is not min, and sometimes there is no max. The lack of min is done by using the parameter useMin, while the lack of max is done by max < min.
My predicament is the following call:
validateNumber(text, -2);
Now, max will be used, even though I don't want it. Ideally, I would want to do something like... int max = (min - 1), ... but that doesn't work. I also can't check to see if the parameter hasn't been changed (that I know of), because the following call would make it look like it hasn't
validateNumber(text, -2, -1);
So the question is, is there a way to do what I want, without having to add in a bool useMax parameter? Or is this my only option? I don't want to do that for simplicity, but if I have to, I have to.

Unless I'm missing something, it's now possible(ish)? A little concept is below, very rough around the edges. Still though, if this is valid by standard C++, why can't we have built-in support for float / double template parameters?
#include <iostream>
#include <tuple>
template<int Numerator, int Denominator>
struct Float {
constexpr static float value()

I have run into a problem which is mostly just an annoyance. I need to know if i can have pass a derived class to a function which has the base class as its parameter. For example i have been creating a program but i have a function which needs to work for multiple classes all derived from the BaseObject class
Code :
class folder : public BaseObject
{}
class BaseObject
{void function(BaseObject B)}
how would i get the following to work:
function(folder)
