Why send PDDW similar to the window of the edit box message failure-CodePudding

I used to a PDDW sendmessage (class name: pbdw90) similar to the window of the edit box to send messages fails, what should I do?
I was written in easy language to a pb application message

What are you going to send information?

The example below

Here, of course, refers to a program that reads data window in another program, there are many methods of the vision, the simple method is to the data window message! Consider this:

By testing found that using Post (ll_dw_handle, 1305, 0, 0), can make the data window pop-up dialog saveas, after further experiment, found the wparam and lparam parameters are: the meaning of saveas type and savefilename the address of the string, so we can use of sending a message to make data window content is saved as a text file, and then read the file can get data,
I test code in the pb application:
The Function of integer SndMsg (long hWnd, long uMsg, long wp, & amp;
Ref string filename) library "user32. DLL" Alias For "SendMessageA
"Long ll_dw_handle
Ll_dw_handle=handle (dw_1)
String s
S="c: \ 111. TXT"
SndMsg (ll_dw_handle, 1305, 2, s)
If you want to write a data window plugins, just get the data window handle, I will point here so far,

I want to send the id number

CodePudding user response:

To pbdw90 window above not clear, I am sending an id number

CodePudding user response:

reference 4 floor yxd_666666 response:

above not clear, I'm going to send an id number to pbdw90 window

Send the id number, this is a content, news is wm_settext?

Settext cannot send dw, because dw itself cannot be edited, when you click on a column, pb generates a on the column on the edit box, you can grab handle to the edit box, and then send the wm_settext

CodePudding user response:

I use a window detector to detect only pbdw90 window, no edit box appears

CodePudding user response:

I test code in the pb application:
The Function of integer SndMsg (long hWnd, long uMsg, long wp, & amp;
Ref string filename) library "user32. DLL" Alias For "SendMessageA
"Long ll_dw_handle
Ll_dw_handle=handle (dw_1)
String s
S="c: \ 111. TXT"
SndMsg (ll_dw_handle, 1305, 2, s)

This code will result in pb software breakdown

Use the following function can capture the edit box

WindowFromPoint

VB statement
Declare the Function WindowFromPoint Lib "user32" Alias "WindowFromPoint" (ByVal xPoint As Long, ByVal yPoint As Long) As Long
Description
Return contains a handle to the window of the specified point, ignore the shielding and hidden and transparent window
The return value
Long, contains a handle to the window of the specified point, such as the point where the specified window does not exist, it returns 0
Parameter list
The parameter types and description
XPoint Long, x value
YPoint Long, y point value

No, or taken the pbdw90 window handle

CodePudding user response:

Also suggested that the current focus only when the data window will have the edit box, if the focus switched to another window, the edit box, there is no

If you still can only obtain pbdw90 window handle, there is no way
