void   fol_dckl(int typ)
{
         Form3->Button1->Enabled=false;
         Form3->Cursor=crAppStart;
         if(typ==1)
                 NAME=Form3->Edit1->Text+"\\"+NAME;
         Form3->Edit1->Text=NAME;
         strcpy(spath,NAME.c_str());
         Form3->ListView->Items->Clear();
         int g=-2;
         while(Form1->sock[1]->SendBuf(&g,sizeof(int))<0);
         g=strlen(spath);
         g++;
         while(Form1->sock[1]->SendBuf(&g,sizeof(int))<0);
         while(Form1->sock[1]->SendBuf(spath,g)<0);
}

that function is called to send a folder name to the other side.
in the other side sock[2] receives it and calls the following function
to send back the folder data so it can be viewed.

void __fastcall TForm1::Send_fdata(char *ph)
{
         TSearchRec sr;
         int t;
         t=FindFirst(AnsiString(ph)+"\\*.*",faDirectory,sr);
         if(sr.Name.SubString(1,1)==".")
         {
                 FindNext(sr);
                 t=FindNext(sr);
         }
         ffiles="";
         FDATA="";
         int file=0;
         int w=-1;
         while(t==0)
         {
                 if(sr.Name=="AUTOEXEC.BAT" || sr.Name=="CONFIG.SYS")
                 {
                         t=FindNext(sr);
                         continue;
                 }
                 if((sr.Attr & faDirectory)==0)
                 {
                         file++;
                         ffiles+=sr.Name+"*0"+AnsiString(sr.Size)+"?";
                 }
                 else
                 {
                         FDATA+=sr.Name+"*1";
                 }
                 t=FindNext(sr);
         }
         FindClose(sr);
         if(file>0)
                 FDATA+=ffiles;
         FDATA+="\0";
         fData=FDATA.c_str();
         int sz=FDATA.Length();
         sz++;
         while(Form1->sock[1]->SendBuf(&w,sizeof(int))<0);
         while(Form1->sock[1]->SendBuf(&sz,sizeof(int))<0);
         while(sz>count)
         {
                 if(Form1->sock[1]->SendBuf(fData,count)<0)
                         continue;
                 sz-=count;
                 fData+=count;
         }
         while(Form1->sock[1]->SendBuf(fData,sz)<0);
}

the code above works pretty good. The problem occurs when both users on 
each side click on a folder (any folder). Of course the more files the 
folder contains the bigger the possibility of an error to occur. I 
believe that what happens is that among the send_fdata function the 
fol_dblk can be called and try to send data since the folder data is not 
sent immediately in one sendbuf call there can be confusion when amongst 
these calls other calls take place. that's why i wanted to know if the 
socket was idle. because i wasn't dealing with one sendbuf call but with 
many. Does anyone know for sure if i add a bool variable that will be 
true before the calls and false soon after would do? of course that 
would be included in one function and the other just before the start of 
the sendbuf calls could do a while(var);.

Thanks anyway
