If you call GetWindowText from an external application you would not be able to get the text. You can inject code into the external application using hooks and then try to use GetWindowText on the control.

For the mouse movement, there is an API called SetCursorPos to move the mouse cursor. Or you could try sending the WM_MOUSEMOVE message with the button states and the new position.

Regarding the hooks. Due to somesecurity issues with the application and and the vendor..I will stay away from it for now unless I am really stuck I will use hooking.

Ok..I am able to set the mouse to the starting point of the text.
What you suggesting I have tried. Without releasing the button I moved it to the new position I wanted but the text is not hilighting. Not sure because of the moving the button gets released.

Here is the actual Code I used...

GetCursorPos CurMouse
SetCursorPos LongX, LongY
mouse_event MOUSEEVENTF_LEFTDOWN 0&, 0&, 0&, 0&
SetCursorPos CurMouse.X, CurMouse.Y
at this point I wanted the text highlighted but it is not.

In that case, I guess you would need to try and send the WM_MOUSEMOVE message.

Yeah..However If I can get some help on my bitmap issue. this will not be required.

trying hard to get this going it was one of the main reasons I moved to C++. Was strugling with it in VB for the last3 to 4 months and I think I might have this solved with a little more help.

Thanks a million. I do appreciate all the help from everyone here.

You probably need to use unicode.

This is what i'm doing...

_bstr_t bstrString_Ini;
 _bstr_t bstrString_Tag;
 _bstr_t bstrString_Dest;
 char sqlQuery[2 * MAX_PATH] = "";
 sprintf(sqlQuery, "SELECT IniSection,TagName,DestinationValue FROM %s WHERE FileName = '%s'" , szTableName, szstr);
 _bstr_t sqlQueryText(sqlQuery);

 try
 {
     ADODB::_CommandPtr m_objCmdSearch;
     ADODB::_RecordsetPtr m_cpRecordsetSearch;

     //Create instance of command object
     HRESULT hr = m_objCmdSearch.CreateInstance("ADODB.Command");
     if(SUCCEEDED(hr))
     {
         //Set the active connection property of command object to open connection
         m_objCmdSearch->ActiveConnection = m_cpConnection;

         //Set command object's command type to text
         m_objCmdSearch->CommandType = ADODB::adCmdText;

         //Set Command Text
         m_objCmdSearch->CommandText = sqlQueryText;

         //Execute command and get results in Recordset object
         m_cpRecordsetSearch = m_objCmdSearch->Execute(NULL, NULL, ADODB::adCmdText);
         if(m_cpRecordsetSearch != NULL)
         {
             if(!m_cpRecordsetSearch->GetEndOfFile())
             {
                 char szstr[MAX_PATH];
                 char szstr1[MAX_PATH];

                 m_cpRecordsetSearch->MoveFirst();

                 while(!m_cpRecordsetSearch->EndOfFile)
                 {
                     bstrString_Ini = m_cpRecordsetSearch->Fields->GetItem("IniSection")->GetValue().bstrVal;
                     bstrString_Tag = m_cpRecordsetSearch->Fields->GetItem("TagName")->GetValue().bstrVal;
                     bstrString_Dest = m_cpRecordsetSearch->Fields->GetItem("DestinationValue")->GetValue().bstrVal;

                     m_cpRecordsetSearch->MoveNext();
                 }


                 rVal = TRUE;
             }

             if((m_cpRecordsetSearch->State &  ADODB::adStateOpen) != 0)
             {
                 m_cpRecordsetSearch->Close();
                 m_cpRecordsetSearch = NULL;
             }
         }

         m_objCmdSearch->PutRefActiveConnection(NULL);
     }
 }

And i get "Abc ????" in bstrString_Dest... Which is defined as _bstr_t...

bstrString_Dest = cpRecordsetSearch->Fields->GetItem("DestinationValue")->GetValue().bstrVal;

What else do i need to do.. I've enabled unicode in my project..

How did you determine what is in that variable (traced it out, pointed at it and checked the tooltip in VS, ...)? Are you sure the database correctly contains the chinese chars?

Yes i'm sure that database correctly contain chinese char (I saw it).. And i can see the value of that variable in tooltip only.. Other int values comes out perfect but this chinese stuff which is in last field, it only shows "????"..

Am i missing some setting or do i need to use other data type ?

Thanks

I'm not sure but i suspect that the tooltip simply doesn't handle the chinese chars...try to save the string into a txt file for example and then open it in word or such and see if it displays the chinese chars or not (you might need to select the right charset to actually see something usefull).

I tried.. I printed all the results into text file but result remains same.. some text in English followed by question mark...
I even tried putting in MS-Word file..But same result..

What happens if you retrieve the string into CString instead of _bstr_t ? Btw if you check out the string as a byte array, what do you get at the place of questionmarks? Can you maybe upload that text file somewhere for me so i can take a peak?

Try outputting the string and check whether it is really some junk characters or you were just unable to view it properly.

You could do this.

MessageBox(0, (wchar_t*)bstrvariable, 0, 0);

That give some hope..When i use MessageBoxW it doesn't give "????" , rather that it give some junk character (Might be chinese which is not supported in messagebox).. Trying to print into notepad..

Re: Displaying Chinese character.

I believe the characters are encoded in the multi-byte character set.
So you should first extract the characters into a char array instead of wchar_t array or string variable instead of wstring variable or you can explicitly use CStringA instead of CString.

After getting it into the variable, convert the multi-byte characters into wide characters using the MultiByteToWideChar API.
Now use that in a MessageBoxW function.

I just did this to print data on file...

(char *)(wchar_t*)bstrString_Dest

And it's printing chinese character... That was just a blind try..how did it work..Can someone explain?

Re: Displaying Chinese character.

gothic_coder8-Mar-09 23:56

I did this...

bstrString_Dest = m_cpRecordsetSearch->Fields->GetItem("DestinationValue")->GetValue().bstrVal;

Extracted the character in char array..

strncpy(bstrString_Dest_Char,(char*)bstrString_Dest, sizeof(bstrString_Dest_Char));

Converted using MultiByteToWideChar..

TCHAR wsz[MAX_PATH];

MultiByteToWideChar(CP_ACP, 0, bstrString_Dest_Char, -1,
(wchar_t*)wsz, MAX_PATH);

Printed using Messagebox

MessageBoxW(0, (wchar_t*)wsz, 0, 0);

But same result Frown | :(

<quote>Use wchar_t instead of TCHAR

Changed it to this

wchar_t wsz[MAX_PATH];
MultiByteToWideChar(CP_ACP, 0, bstrString_Dest_Char, -1,wsz, MAX_PATH); 
MessageBoxW(0, wsz, 0, 0);

and this..

wchar_t wsz[MAX_PATH];
MultiByteToWideChar(CP_ACP, 0, bstrString_Dest_Char, -1,(wchar_t*)wsz, MAX_PATH); 
MessageBoxW(0, wsz, 0, 0);

But Same result...Gossh what am i doing wrong?
