I appear to have found a solution, and it does not require invoking OS level setting changes.
Through a lot of trial and experimenting, I found the behavior is specifically related to the DataGridView control. Through some research, an old thread proved to have a workable answer: Invoking DoubleBuffered on the control.
The details are on StackOverFlow: [^]
The code is here:
typeof(DataGridView).InvokeMember(
"DoubleBuffered",
BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.SetProperty,
null,
myDataGridViewObject,
new object[] { true });OR
DataGridView1.GetType.InvokeMember("DoubleBuffered", Reflection.BindingFlags.NonPublic Or Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.SetProperty, Nothing, DataGridView1, New Object() {True})

VB uses Unicode for strings so you should use SendMessageW not SendMessageA.
|

hi
SendMessageW (For All even get lenght ?) i use now but when itemCode change ( ODA_SELECTED ) buff$ no clear
,possible to put a right code if you are tested before ?
|
|
|
|
|
Sorry, I don't understand what you mean by "buff$ no clear". Using SendMessageW ensures that any text strings returned will be in Unicode format.
|
|
|
|
|
means set buff$ empty , am i wrong ? in EM_SETCUEBANNER Also shows unicode(not related to this post but maybe you know the way to solve it )
after each selection no need empty the buff$?
|
|
|
|

The result of LB_GETTEXTLEN is :
Quote: The return value is the length of the string, in TCHARs, excluding the terminating null character.
So you need to allocate a buffer at least this length plus 1. The LB_GETTEXT message will fill the buffer with the text of the control, followed by a NULL character (hence the +1 in the previous part).
The EM_SETCUEBANNER message also needs to be sent with SendMessageW. In fact you should use the W suffix on all Win32 calls, as all your text will be Unicode. Unless, of course, you add some text manipulation to make it ASCII.

Assuming I have truyen.exe file, I want to give notice to truyen.exe file to output the message with the syntax: Drive:\truyen.exe "example communication", I want to pass the file to truyen.exe. how to declare exe yourself ?

Hmmm your message suffered badly in translation and you question is very unclear.
Fact: VB6 is no longer supported and has not be for more than a decade. Most of us have moved on from that language.

hi
i Subclass a Window ( other app ) and Create Button inside it but not receive any message even wm_command , when use tab not get focus
|
|
|
|
|
Your quesiton isn't answerable as is. All of the important information is missing.
Show the code you used to create this window and button. And what do you mean by "other app"?
|
|
|
|

Subclass The InputBox ( Not Create Window ) And Create Button
hwndBtn=CreateWindowEx(0,"Button","",WS_CHILD Or WS_VISIBLE,300,60,49,26,hwnd,IDC_BTN3,0,0)
So Created In Window But Not Recieve Any Message Example Not Get Focus
i used follwing document also
WS_TABSTOP0x00010000L : The window is a control that can receive the keyboard focus when the user presses the TAB key.
InputBox Have 2 Buttons , 1 Static And 1 Edit Control
i Created another button inside it behind the button(cancel)
My Friends I ve created button !!!!
see third case
Select Case WM_COMMAND
Case 1 ' IDOK
SetWindowTexta hwnd,"ok"
Case 2 ' IDCANCEL
SetWindowTexta hwnd,"Cancel"
Case IDC_BTN3 ' <--- Does Not Work
SetWindowTexta hwnd,"New BTN"
End Select
***Note :
when hook and subclass the inputbox I did not recieve WM_INITDIALOG so that i can Put the createButton Code finally put the code in WM_SHOWWINDOW to create it

A single line of code does not explain anything at all. There are many places where you could put that and it would not work. Please edit your original question and add some proper details.
|
|
|
|
|
This is clear , the Button not recieve any message from its parent and my question and problem clearly specified maybe somebody did it and can help me
|
|
|
|
|
No, your problem is not clearly specified, and we have no idea where that CreateWindowEx call is going, or how the parent is sending messages to it.
|
|
|
|
|
As per your comment if button or any control create with CreateWindowEx function through Hooking-Subclasong , that button never get focus and needs Buttonproc ?
|
|
|
|
|
I have used similar calls many times without problems.
|
|
|
|
|
So Why third Case in mentiond code ( Case IDC_BTN3 ) Has not any reflect , Example if push Button "Ok" Or "Cancel" the Window Closed
|
|
|
|
|
You re right With WS_TABSTOP Get Keyvboard Focus and with SetWindowpos Can Change the Tab Order For Apply Command For Created button I Used Following
case WM_COMMAND
if lparam=hbtn Then SetwindowTexta hwnd,"Clicked Me"
Select Case wparam
Case 1
Case 2
End Select

Error states: Make sure that the product is installed properly.
Run the installer again (without uninstalling it ofc).

Good day friends!
I don't know the right words to use cos I have no idea of the name this could be called.
Am trying to write a program in .Net language (VB or C# to be specific) that can I use to control a small car i.e when I click on start, the car should move so on and so forth.
I know this is a broad question so what I want is to know the right keywords to use when searching on google, relevant links and videos if possible.
In a short form, I want to build my own hardware device then control it from my own designed application.
Thanks!

Remote Control may be what you are looking for possibly wireless remote control. I would look at the hardware you are going to use first and worry about the control mechanism after you have decided what hardware you are going to use.
