c# - Receiving strangers strings in target window from PostMessage api -


i have remote administration tool, , i'm trouble when receives strings in window postmessage api. strings sent through of textbox componente in server application.

for example, word coder in stackoverflow window stays this:

enter image description here

and code i'm using this:

server application

       private void tenviartexto_click(object sender, eventargs e)         {              string message = string.format("<|msg|>{0}", tenviarmsg.text);             listviewitem item = listview_clients.focuseditem;             string clientid = item.name;             remoteclient client = this.remoteclientmanager.getclientbyid(clientid);             if (client != null)             {                 try                 {                     client.mremessage.waitone();                     client.queuemessage.addmessage(message);                     tenviarmsg.text = "";                 }                  catch (exception ex) { messagebox.show(ex.tostring()); }             }         }

client application

       public void enviatextohwnd(string texto)         {             foreach (char caractere in texto)             {                 int charvalue = caractere;                 string hexvalue = charvalue.tostring("x");                 intptr val = new intptr((int32)caractere);                  string valor = val.tostring();                  if (valor == "66") // letra b no operador                 {                     postmessage(windowhandle, wm_keydown, new intptr(vk_back), new intptr(0));                     postmessage(windowhandle, wm_keyup, new intptr(vk_back), new intptr(0));                  }                 else if (valor == "83") // letra s no operador                 {                     postmessage(windowhandle, wm_keydown, new intptr(vk_space), new intptr(0));                     postmessage(windowhandle, wm_keyup, new intptr(vk_space), new intptr(0));                  }                 else                 {                      postmessage(windowhandle, wm_keydown, val, new intptr(0));                     postmessage(windowhandle, wm_char, val, new intptr(0));                     postmessage(windowhandle, wm_keyup, val, new intptr(0));                  }              }         }

and usage:

public void communicationproc()     {        while (this.connected)         {          else if (message.indexof("<|msg|>") == 0)           {             string[] strsplit = value.split(menuremoteclient.separator, stringsplitoptions.none);             string msg = strsplit[0]; // content textbox on server application                     if (this.remotednav)                      {                        thread sendtextohwnd = new thread(() => enviatextohwnd(msg));                            sendtextohwnd.start();                             }                         }                 }              }

so, how solve it?

any suggestions or guidance here appreciated.

fixed: 

             //   postmessage(windowhandle, wm_keydown, val, new intptr(0));                 postmessage(windowhandle, wm_char, val, new intptr(0));             //    postmessage(windowhandle, wm_keyup, val, new intptr(0));
