Hi, I wondering if it is possible to call a main with its parameters from another method?
From the example shown below.
<br />
<br />
int test(int argc, char *argv[])<br />
{<br />
<br />
}<br />
<br />
<br />
void example()<br />
{<br />
test(int argc, char *argv[]);<br />
}<br />
Can can the parameters be altered in the example method which doesn't mean altering the parameter list in the test()?

It is possible to call the main function from another function. but the
int argc, char *argv[] in example method are local variables of example. u cannot access the int argc, char *argv[] in main from example.

main is a function hence you can call it from another function (but then you have to find a way to stop recursion).
There isn't main in the posted code.
gman2008 wrote: void example()
{
test(int argc, char *argv[]);
}
The above code is wrong, use, for instance
void example()
{
char * argv[]={"appname", "foo"};
test(2, argv);
}

Ok maybe i'm having a bad day  , but for the life of me I can't find any information on how to change the permissions for the 'all users\application data' folder.
During install, I want to install a file to this folder (app.ini). I want to be able to give all users read and write permission to this folder and file. I can get the file installed ok, but it defaults to Read only.
The actual path is:
C:\Documents and Settings\All Users\Application Data\company\appname\app.ini
My installer is MSI that comes with Visual Studio 2005 and I'm using MFC/C++. I may need to create a Custom Action DLL. Not a problem. Just can't figure out how to set the permission of the folder/file to read, write, modify.
Thanks.

Anyone ever seen this one before? Any hints? We have an app which is producing this error. We get a message box which pops up with this text. The app is native C++/MFC.
|
|
|
|
|
We found the issue. It appears this message is originating from MFC CArchive serialization over a socket when invalid data is sent. So if you see this thats a good area in which to look.
|
|
|
|
|
Since message boxes are modal just breaking the application in a debugger and looking at the call stack should take you straight to the problem.

Have you considered:
static int arCombs[11][6] =
{
{i1,i2,i3,i4,i5,i6},
{i7,i8,i9,i10,i1,i2},
{i8,i9,i10,i1,i2,i3},
{i9,i10,i1,i2,i3,i4},
{i10,i1,i2,i3,i4,i5},
{i1,i2,i3,i4,i5,i7},
{i1,i2,i3,i4,i7,i8},
{i1,i2,i3,i7,i8,i9},
{i1,i2,i7,i8,i9,i10},
{i1,i6,i7,i8,i9,i10},
{i5,i6,i7,i8,i9,i10}
};BTW, unless you are strictly targeting German-speaking readers, you might want to consider changing your profile to English.

I was about to suggest the code below, but then I've tried it in a compiler and I got an error.
static int arCombs[6][11] =
{
{i1,i2,i3,i4,i5,i6},
{i7,i8,i9,i10,i1,i2},
{i8,i9,i10,i1,i2,i3},
{i9,i10,i1,i2,i3,i4},
{i10,i1,i2,i3,i4,i5},
{i1,i2,i3,i4,i5,i7},
{i1,i2,i3,i4,i7,i8},
{i1,i2,i3,i7,i8,i9},
{i1,i2,i7,i8,i9,i10},
{i1,i6,i7,i8,i9,i10},
{i5,i6,i7,i8,i9,i10}
};
The dimensions are wrong. You are declaring an array of 6 arrays of 11 elements, not an array of 11 arrays of 6 elements. But you only initialize 6 of those 11. The rest get the default value, 0.
So the correct way should be:
static int arCombs[6][11] =
{
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11},
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11},
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11},
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11},
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11},
{i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11}
};
or even
static int arCombs[6][11] =
{
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11,
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11,
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11,
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11,
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11,
i1,i2,i3,i4,i5,i6,i7,i8,i9,i10,i11
};
I just copied and pasted the values, but you get the picture

If I use the GDI+ Region::Union(RectF&) method to include 3 GDI+ RectF objects, if I go back and use Region::GetRegionScans(), I don't always get the original 3 rects if there is a simpler way to describe the region. This occurs if two or more connected rects can be described by one larger rect. Is there a way to force the region to preserve the original rects and not simplify the solution to Region::GetRegionScans() or is the simplification inherent in how Regions are stored?

I think the info about original rects is simply discarded.
MSDN [^]states
Region.GetRegionScans Method
Returns an array of RectangleF structures that approximate this Region object.
and the above, IMHO, enforces my hypothesis.

Ditto on CPallini's reply.
Maybe store the rects in a GraphicsPath and use that to make a
Region when you need one...

Heh. No need to thank me - I don't think I helped but I threw it out there
anyway just in case. I know you know what you're doing

I am updating my old MFC app to Vista look app

I have an edit control that takes up the majority of space on my app. I am receiving continuos data from a port and would like to display each message separated by "\r\n".
I tried using the control variable and the value variable for my edit control to display these items. No matter what i try , it only displays the first item and not the rest.
I have used the method "SetWindowText"
I also use UpdateData(FALSE) to update the screen
How does one use these vars to display the continuos data in an edit control?
|
|
|
|
|
Isn't a list control (a list box or a list view ) more appropriate, is it?

How are you doing this?

I simply have a control variable for my edit control
call it m_Control.
I have a string variable for that same edit control.
call it m_strValue.
I do something like
//using the string var
for (int lop=1; ;lop<100;lop++)
{
m_strValue = data[lop];
UpdateData(FALSE);
}
///////OR
for (int lop=1; ;lop<100;lop++)
{
m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
}
|

Neither of these will preserve what is currently in the edit control.
LCI wrote: m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
When using a CEdit control, or any other time for that matter, UpdateData() is not necessary.
You can do something like:
for (int lop = 1; lop < 100; lop++)
{
CString str;
m_Control.GetWindowText(str);
str += data[lop];
m_Control.SetWindowText(str);
} Or you could just continually add to the end of the edit control as has already been suggested.

Since you are trying to update a window while you are in a tight loop, you need to realize that the window will not process any messages until the loop completes. The UpdateData puts a message in the queue to be processed, but it isn't processed immediately.
To overcome this, try
for (int lop=1; ;lop<100;lop++)
{
m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
m_Control.UpdateWindow();
}
The call to UpdateWindow bypasses the normal message queue and causes the window to repaint immediately.
Hope that helps.
