One last thing, side c#,
I receive data normally using this:
byte[] buffer = new byte[1500];
int iRx = sck.Receive(buffer);
char[] chars = new char[iRx];
System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
int charLen = d.GetChars(buffer, 0, iRx, chars, 0);
System.String szData = new System.String(chars);

and then I print in listview like so:

listView1.Items.Add(szData)));

-----------------------------------------
But if I have to create the Icon, I have to use DIBSECTION ds to create the image/icon;

width = ds.dsBm.bmWidth;
height = ds.dsBm.bmHeight;
stride = ds.dsBm.bmWidthBytes;
ecc...
But how I can convert byte that I have received to DIBSECTION ds?
So if I convert byte array to ds I can use ds to create the Icon.

thank you

You think this should be correct?
I have substituted that condition with tihs if:
if(!nSizeDS){//failure}
else{//is a DIB}

here there the complete part of code:

ICONINFO oIconInfo;
if (::GetIconInfo(icon, &oIconInfo))
{
// Get bitmap info for colour mask
DIBSECTION ds;
int nSizeDS = ::GetObject(oIconInfo.hbmColor, sizeof(ds), &ds);
if(!nSizeDS){
cout <<"Failure!"<<endl;
}else{
// is a DIB
cout <<"Success!"<<endl;
// Send the DIBSECTION
send(newConnection, (CHAR*)&ds, sizeof(ds), NULL);
// Send raw bitmap
send(newConnection, (CHAR*)ds.dsBm.bmBits, ds.dsBmih.biSizeImage, NULL);
}
}

When I try that piece of code,the if (sizeof(ds) == nSizeDS) condition, isn't ever verified.
How about using the two send without this if (sizeof(ds) == nSizeDS) ?
In this case without the if condition works, but I'm afraid this should be wrong.

Yes sorry I read, and I have deleted this last my question from here, but maybe to late.

Member 12891988 6-Apr-17 6:03am View

Thanks a lot Jochen I will try.

It means that I have to send via socket: ds.dsBmih and oIconInfo?
like this:
send(newConnection,(CHAR*)&ds.dsBmih,sizeof(ds.dsBmih),NULL);
send(newConnection,(CHAR*)&oIconInfo,sizeof(oIconInfo),NULL);

And via c# getting: width, height, stride, colour depth, and byte array, from ds.dsBmih that I have received from server, or in the server I have to do multiple sending?
One sending for width,one for height,one for stride, ecc...
I do not understood this

I've tryed this, but I do not know How to continue:

ICONINFO oIconInfo;
DIBSECTION ds;
if(::GetIconInfo(icon, &oIconInfo)==true){
HBITMAP hBitmap = oIconInfo.hbmColor;
int nSizeDS = ::GetObject(hBitmap, sizeof(ds), &ds);
// hBitmap is a DIB
if (0 == ds.dsBmih.biSizeImage)
{
if (0 == ds.dsBm.bmWidthBytes)
ds.dsBm.bmWidthBytes = ((ds.dsBm.bmWidth * ds.dsBm.bmBitsPixel + 31) & ~31) / 8;
ds.dsBmih.biSizeImage = ds.dsBm.bmHeight * ds.dsBm.bmWidthBytes;
}
send(newConnection,(CHAR*)&oIconInfo,sizeof(oIconInfo),NULL);
}

Hi, thanks and sorry but I have not to understood well you example, more exactly I do not understood what I should send to client via socket.
I tryed to do this:

HICON icon = (HICON)GetClassLong(hWnd, GCL_HICON);

ICONINFO oIconInfo;
if(::GetIconInfo(icon, &oIconInfo)==true){
cout <<"Success!"<<endl;
send(newConnection,(CHAR*)&oIconInfo,sizeof(oIconInfo),NULL);
}else{
cout <<"Failure!"<<endl;
}

But I do not know how to send the other that you said.
Can You give a simple example combining with my little solution?
PS. I need to do multiple sending?
Before I send this:
send(newConnection,(CHAR*)&oIconInfo,sizeof(oIconInfo),NULL);
and then I send:
BITMAPINFOHEADER bitmapinfoheader;
send(newConnection,(CHAR*)&bitmapinfoheader,sizeof(bitmapinfoheader),NULL);

I do not know how can do in practically.

Member 12891988 5-Apr-17 18:32pm View

Thanks a lot, I think to have solved about send in server side:

HICON icon = (HICON)GetClassLong(hWnd, GCL_HICON);

ICONINFO oIconInfo;
if(::GetIconInfo(icon, &oIconInfo)==true){
cout <<"Success!"<<endl;
send(newConnection,(CHAR*)&oIconInfo,sizeof(oIconInfo),NULL);
}else{
cout <<"Failure!"<<endl;
}

Now I have to convert the stream of byte read from my client(this is made in c#) that I have received from my c++ server, and convert the array of bytes to an Image.
So I have tried to do this:

byte[] buffer = new byte[1500];
sck.Receive(buffer);
TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));
Bitmap bitmap1 = (Bitmap)tc.ConvertFrom(buffer);
imageList1.Images.Add(bitmap1);

When I try this, I receive an error at this line:

Bitmap bitmap1 = (Bitmap)tc.ConvertFrom(buffer);

This is the message error that I have received:

Unhandled exception of the 'System.ArgumentException' type System.Drawing.dll
Additional information: Invalid parameter.

I have also tried:

MemoryStream ms = new MemoryStream(buffer);
Bitmap bmp;
bmp = new Bitmap(ms);

and this other:

ImageConverter ic = new ImageConverter();
System.Drawing.Image img = (System.Drawing.Image)ic.ConvertFrom(buffer);
Bitmap bitmap1 = new Bitmap(img);

but I have received the same error message.

Hi,I need one more advise, I am aware that there are ways to check if a process is already running (via enumeration). However, I was wondering if there was a way to listen for when a process starts and ends (for example, notepad.exe) and then perform some action when the starting or ending of that process has been detected. I assume that one could run a continuous enumeration and check loop for every marginal unit of time, but I was wondering if there was a cleaner solution.
Thancks in advance
Regards

Thank you so much for your help.
I will try.

I do not know how to send a command from keyboard to interact with process on focus.
For example: I have in the server side machine firefox opened and when I press ctrl*f from my keyboard a searching bar was opened.
So I would do the same thing, but pushing ctrl+f from my client machine and open searching bar in firefox installed on server machine.
I just want to use command from my keyboard to interact with a window application.
and after I do not push enter or send,I only want that: if I push ONLY ctrl server must receive it, if i push ctrl+f server must receive it and so on.

Member 12891988 14-Mar-17 4:49am View

Thanks for your reply.
I do not know how I can send a command(ctrl+c for example) from client to the server.
I know how send a buffer of char or string but I do not know how I can send a combination of key from keyboard.
