I am a post at old demon StringGrid for acquiring external program content, and an external program is now TdzDrawGrid, preliminary judgment is succeeded by TDrawGrid, also want to get him the data content, but there is no cells drawgrid content, so how to get his cell content value,
Old demon of parts attached code

 
The function MsgWndProc (HWND: HWND; Msg: UINT; WParam: WParam; LParam: LParam) : LRESULT; Stdcall; 
Var 
//SG: TStringGrid; 
SG: TDrawgrid; 
X, Y: Integer; 
The begin 
Case Msg of 
CM_QUERYROW: 
The begin 
Result:=1; 
If P ^. DestWnd & lt; & gt; 0 then 
The begin 
SG:=Pointer (FindControl (P ^. DestWnd)); 
If SG & lt; & gt; Nil then Result:=SG. RowCount; 
end; 
Exit; 
end; 
CM_QUERYCOL: 
The begin 
Result:=1; 
If P ^. DestWnd & lt; & gt; 0 then 
The begin 
SG:=Pointer (FindControl (P ^. DestWnd)); 
If SG & lt; & gt; Nil then Result:=SG. ColCount; 
end; 
Exit; 
end; 
CM_HOOKCELL: 
The begin 
Result:=1; 
P ^. Text [0] :=# 0; 
If P ^. DestWnd & lt; & gt; 0 then 
The begin 
SG:=Pointer (FindControl (P ^. DestWnd)); 
If SG & lt; & gt; Nil then 
The begin 
X:=WParam; 
Y:=LParam; 
If (X & gt;=0) and (X & lt; SG. ColCount) and (Y & gt; Y=0) and (& lt; SG. RowCount) then 
The begin 
Result:=Length (SG) Cells (X, Y));//is the cell value here for less than it? 
If the Result & gt; 0 then 
The begin 
StrPLCopy (P ^. Text, SG. Cells (X, Y), 1024); 
end; 
end; 
end; 
end; 
Exit; 
end; 
end; 
Result:=DefWindowProc (HWND, Msg, WParam, LParam); 
end;

Tracking, see cells (x, y), x, y is correct

CodePudding user response:

Upstairs may never see clear my question,
The key is drawgrid cells property, how to obtain the cell contents

CodePudding user response:

But I will copy is an external program, through GetClassName access to its use is TdzDrawGrid controls, preliminary judgment may be their company to write their own a TDrawGrid inherited controls, so here I can get the value?
If not, can have other measure?
From the point of caught tools, their companies are using the TCP protocol,

CodePudding user response:

No one know?
Drawgrid how to write content of cells?

CodePudding user response:

DrawGrid provide only canvas, so it is unable to extract data from the DrawGrid controls, unless the image recognition

CodePudding user response:

I also found a image recognition, just according to the location of the mouse to stay then go to capture text,
So now if I want to get across multiple columns and column, such as the first column, the third column, the fourth column of the data will be more trouble,
Say again when the data volume of more than 1000, more unable to get data, I want to
Can't think of way, beg CSDN great god provides the train of thought,

CodePudding user response:

How no one huh??????

CodePudding user response:

May not be able to solve this problem,,,,,,,,,,,,,,,

I also want to know, please explain!
