My project comment such as:
* A class CBall: to load,clear a bitmap picture of ball.
//Pixel: to get pixel color of range of rectangle of bitmap.
//nWidth,nHeight: width and height of bitmap.
void CBall::Pixel(HDC hdc)
{
int i,j;
for(i=0;i<this->nWidth;i++)
for(j=0;j<this->nHeight;j++)
this->pixelColor[i][j]=GetPixel(hdc,this->nXDest+i,this->nYDest+j);
}
//Draw: Load bitmap
//nXdest,nYDest: co-ordinate upper-left of bitmap
void CBall::Draw(HDC hdc,HDC hdcMem)
{
SelectObject(hdcMem,this->hBitmap);
BitBlt(hdc,this->nXDest,
this->nYDest,this>nWidth,this->nHeight,hdcMem,0,0,SRCCOPY);
}
//Clear: to clear bitmap
//By uses SetPixel() function to set pixel color which get before
void CBall::Clear(HDC hdc)
{
int i,j;
for(i=0;i<this->nWidth;i++)
for(j=0;j<this->nHeight;j++)
SetPixel(hdc,this->nXDest+i,this->nYDest+j,this->pixelColor[i][j]);
}
//Move: to move bitmap
void CBall:Move()
//In main file of project:
*WM_PAINT:
//Call function
ball.Pixel(hdc);
ball.Draw(hdc,hdcMem);
*WM_TIMER:
//Call function
ball.Clear();
ball.Move();
ball.Pixel();
ball.Draw();
//But after clear bitmap, bitmap isn't re-drawn.
//I can't understand. Help me!
//I will send my project for all you if I know your email address. Thanks!

Did you use of a Static Control for show bitmap if yes you can use of MoveWindow

Within my application running on my pc, I wish to browse to files on a connected mobile device using a standard windows open file dialog. Browsing to My Computer does not allow me to select the mobile device, although it does using Windows Explorer. Is there some setting, or some way I can configure the open file dialog to browse to such a system folder?

I'v tried to connect two computers using sockets... it works between computers in the same LAN, and between computers in the same internet subnet.
But, when i try to connect to computers that are far away in the internet(at another city), the connection fails; it simply doesn't reach the listening computer.
I've heared about public and private IPs is this the problem??
How may I fix it up??
Thanks in advance!!

if the remote computer is connected to a router you will have to setup port forwarding on the router. E.G.
something that wont work:
----------------------------
Remote computer(client)
|
Router(without port forwarding)
|
Remote computer(server)
-----------------------------
something that will work:
-----------------------------
Remote computer(client)
|
Router(with port forwarding)
|
Remote computer(server)
-----------------------------

well, the connection works through the router cause i can connect to other computers in the internet that are in the same city...
connection doesnt work connecting to computers in another city...
may it be a problem between nodes??
my public ip (i get it from www.whatismyip.com[^] ) is the same as all other computers i use in my connection so i cannot use this ip because i dont connect to any concrete computer.
i dont know what to do...

You mean all the computers on your LAN have the same public IP? That's normal.
The problem is on the remote end. You need the public IP of the remote to connect to, and if the
remote is on a LAN behind a gateway/router then the remote network needs to be configured to
forward connection requests to the appropriate computer on the LAN. This is usually accomplished
by port forwarding.
Remember an address consists of an IP address and a port number. The port number is used to
identify the application associated with the socket.

Ok, my computer is the "remote computer" that is listening for HTTP incoming connections.
i have my public ip; i try to connect from other computer that is not behind the same gateway.
how to allow forward connection requests to my computer on an internet gateway?
(Could the problem be not in my router but in the internet gateway it connects to??)

Thanks to all!!
Now i know how it is done!!
Just get into router options in "http://(RouterIpAddress)/"

Hi
I have a class named CClipSaver and I want to create an array of this class. I do this as follows:
CClipSaver* Clips[10];
.
.
.
Clips[i]=new CClipSaver;
Clips[i]->Save();
.
.
.
But it crashes!
Note:
When I do not use array (i.e.
CClipSaver * Clip;<br />
Clip=new ClipSaver();<br />
Clip.Save();
) everything works fine.
How should I declare and use the array?
|
|
|
|
|
What is the value of i when it "crashes"? (whatever "crashes" means)
You may be right

Remember that when using arrays
array[10]
the tenth value is
array[9]
the value array[10] is out of the definition and may cause writting out of memory...

hi i have spawned a an executable using shellexecuteEx as
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "textcopy.exe";
ShExecInfo.lpParameters = str;
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_HIDE;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
i wish to check whether "textcopy.exe" is still running....
i want to do sth like
if(process_is_running)
//do something..display some message
else
//continue
but I dont know how to check whether textcopy is still running.
Msdn says it can be done with the help of "ShexecInfo.hprocess"..i dont know how?.Please post some code example.Thnk you..

Something like...
if (WAIT_OBJECT_0 != ::WaitForSingleObject(ShExecInfo.hProcess, 0))
//do something..display some message (process is still running)
else
//continue (process is terminated)

I'm trying to write a quick util to do the following...
1. scan through all subdirectories of a specifiable root dir.
2. calculate the file sizes of all files encountered
3. delete 0-byte files
4. delete empty directories
The key here, is that i'd like to do this in as much ANSI c/c++ as possible, and definitely without using MFC. The reason being, I do not have visual studio at the moment, so the program must compile on dev-c++ or code::blocks IDE.
if anyone can point me to a reference for this it would be appreciated, thanks!

Can you use Windows APIs?
If so, check out FindFirstFile, FindNextFile, FindClose for directory traversal.
The C runtime has equivelant functions but they aren't ANSI compatible.
