When I tried to set my static control position at 0, 0 and size the same as window's size everything worked just fine. Control was placed the same as window, but when i tried to make control smaller and place it so that there's equal amount of space on every side of control it didn't work. At the top there was more space than at the bottom and on the left side ther was more space than on the right side. Could you please tell me how to do what i wanted to do? Code i was using:
1: ghStatic = CreateWindowExW(WS_EX_CLIENTEDGE, L"STATIC", L"Foo", WS_CHILD | WS_VISIBLE | SS_CENTER, 0, 0, 300, 300, hwnd, nullptr, hInstance, nullptr);
2: ghStatic = CreateWindowExW(WS_EX_CLIENTEDGE, L"STATIC", L"Foo", WS_CHILD | WS_VISIBLE | SS_CENTER, 75, 75, 150, 150, hwnd, nullptr, hInstance, nullptr);
Are do you using the CreateWindowExW function to change the size of your hwnd? You cannot use this function to change the hwnd size, it is used to create controls, because it will be trying to recreate what was already created.
Try use MoveWindow function to change the position and size of hwnd:
MoveWindow(YourHWND, x, y, w, h, TRUE);
MoveWindow(ghStatic, 75, 75, 150, 150, TRUE);

I want to change the text that appears on a window. I seem to be able to do it okay but it messes up the area around it and hides the other text. Am I doing it the wrong way perhaps?
So I initialise the variables like this:
static wchar_t socketstatText1T[256];
static wchar_t socketstatText2T[256];
static HWND socketstatText1;
HWND socketstatText2;
I create my text windows like this:
socketstatText1 = CreateWindowW(L"Static", L"Not Connected",
WS_CHILD | WS_VISIBLE | SS_LEFT,
310, 50, 200, 130, hwnd, (HMENU) 0, NULL, NULL);
socketstatText2 = CreateWindowW(L"Static", L"Inactive",
WS_CHILD | WS_VISIBLE | SS_LEFT,
310, 80, 200, 130, hwnd, (HMENU) 0, NULL, NULL);
And then I edit the text like this:
wcsncpy(socketstatText1T, L"Connected to socket", 18);
SetWindowTextW(socketstatText1, socketstatText1T);
This is the same way I change text for a text area and I've had no issues. I've also read that it works the same on text windows. So here a before and after the text change (this happens on a button press).
Before
After
Does anyone know what I may be missing or doing wrong? Any help is much appreciated.
Below is code, which I am using for creating child windows:
case WM_CREATE:
hInst = ((LPCREATESTRUCT) lParam) -> hInstance;
hWnd1 = CreateWindowEx( WS_EX_CLIENTEDGE | WS_EX_LEFT,
"edit", NULL,
WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | ES_MULTILINE | WS_VSCROLL,
0, 0, 0, 0,
hWnd, (HMENU) 1,
hInst, NULL );
hWnd2 = CreateWindowEx( WS_EX_CLIENTEDGE | WS_EX_LEFT,
"edit", NULL,
WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | ES_MULTILINE | WS_VSCROLL,
0, 0, 0, 0,
hWnd, (HMENU) 2,
hInst, NULL );
But this code produces horizontal splitter, and I want vertical splitter.
First I thought, if I change height and width parameters, I could create vertical splitter. But it was of no use.
For full code and sample example (in order to save space on SO):
http://old.sumitbirla.com/software/src/splitter.c
So, what is exactly keyword/parameter, which would produce vertical splitter bar.
The code you posted just creates two child windows. It has nothing to do with vertical or horizontal splitter. Handle the WM_SIZE message in the parent window to position and size the child windows for a vertical or horizontal split.
I created an up-down control by the following code.
HWND hEdit, hUpDown;
hEdit = CreateWindowExW(WS_EX_CLIENTEDGE,
L"EDIT",
Content.c_str(),
ES_LEFT | WS_VISIBLE | WS_CHILD,
600,
260,
100,
25,
hWndParent,
NULL,
hInstance,
NULL);
INITCOMMONCONTROLSEX iccx;
iccx.dwSize = sizeof(INITCOMMONCONTROLSEX);
iccx.dwICC = ICC_UPDOWN_CLASS;
InitCommonControlsEx(&iccx);
hUpDown = CreateWindowExW( 0,
UPDOWN_CLASSW,
L"",
UDS_ARROWKEYS | UDS_ALIGNRIGHT | WS_VISIBLE | WS_CHILD,
0,
0,
0,
0,
hWndParent,
NULL,
hInstance,
NULL);
SendMessageW(hUpDown, UDM_SETBUDDY, (WPARAM) hEdit, (LPARAM) NULL);
SendMessageW(hUpDown, UDM_SETRANGE32, (WPARAM) 0, (LPARAM) 100);
Sleep(5000);
SendMessageW(hUpDown, UDM_SETPOS32, (WPARAM) NULL, (LPARAM) 20);
Sleep(5000);
SendMessageW(hUpDown, UDM_SETPOS32, (WPARAM) NULL, (LPARAM) 60);
I checked the return values of the SendMessageW() functions. They terminate successfully by returning the previous position value as documented.
The created up-down control looks normal:
The problem is, sending the UDM_SETPOS32 message, clicking the up and down arrows and pressing the up and down keys on the keyboard have no effect. I can't change the contents of the edit control (the buddy window of the up-down control) without directly typing something into it. It just stays empty.
I am able to type anything in it manually by using keyboard:
How do I change the position/value of this up-down control by pressing keyboard arrow keys, by clicking the arrows in the GUI and by sending UDM_SETPOS32 in the code? What am I missing in my code?
Use the style UDS_SETBUDDYINT to the up-down control while creating it.
From MSDN documentation:
UDS_SETBUDDYINT
Causes the up-down control to set the text of the buddy window (using the WM_SETTEXT message) when the position changes. The text consists of the position formatted as a decimal or hexadecimal string.
Change the creation code of the up-down control like this by adding the UDS_SETBUDDYINT style:
hUpDown = CreateWindowExW( 0,
UPDOWN_CLASSW,
L"",
UDS_SETBUDDYINT | UDS_ARROWKEYS | UDS_ALIGNRIGHT | WS_VISIBLE | WS_CHILD,
0,
0,
0,
0,
hWndParent,
NULL,
hInstance,
NULL);
This is simple. I created an EDIT control like this:
HWND MYTEXT= CreateWindowEx(WS_EX_CLIENTEDGE, L"EDIT", L"",
WS_CHILD|WS_VISIBLE|ES_LEFT|ES_MULTILINE,
20, 120, 150, 20, hWnd, NULL, hInst, NULL);
but when I type text inside of it I can't type more text than the width of the EDIT control. When I reach the end it's like there's no more space and I get a beep. How can I make the text scroll in this situation?
You can give your edit control the WS_HSCROLL and/or WS_VSCROLL window styles. For instance:
HWND myText
= CreateWindowEx(WS_EX_CLIENTEDGE, L"EDIT", L"",
WS_CHILD | WS_VISIBLE | WS_HSCROLL | ES_LEFT | ES_MULTILINE,
20, 120, 150, 20, hWnd, NULL, hInst, NULL);
Alternately, as Matthew T. Staebler rightfully suggests, use ES_AUTOHSCROLL and/or ES_AUTOVSCROLL (note the ES_ prefix, as these are edit styles, not window styles).
i created a edit box but it doesn't show on the window. it shows if the window is not full screen. if it is full screen the edit box goes behind it. here is the function for the edit box
HWND editbox=CreateWindowA("EDIT", NULL,
WS_VISIBLE | WS_EX_TOPMOST | WS_BORDER | ES_LEFT,
87, 81, 150, 17,
hWnd,
(HMENU)5, hInstance, NULL);
i don't know why it does that i set it to WS_EX_TOPMOST and it still goes behind it. i used directx 9 to make my program in full screen
All WS_EX_** styles should be passed as the first argument of CreateWindowEx, not the third of CreateWindow. This probably causes the problem. Use CreateWindowExA instead.
All the arguments in CreateWindowEx remain the same, there's just one additional parameter at the beginning.
HWND editbox=CreateWindowExA(WS_EX_TOPMOST, "EDIT", NULL,
WS_VISIBLE | WS_BORDER | ES_LEFT,
87, 81, 150, 17,
hWnd,
(HMENU)5, hInstance, NULL);
EDIT: I know what was wrong. You forgot the WS_CHILD style in the third argument. It is needed so Windows knows that this is a child window.
HWND editbox=CreateWindowA("EDIT", NULL,
WS_VISIBLE | WS_CHILD | WS_BORDER | ES_LEFT,
87, 81, 150, 17,
hWnd,
(HMENU)5, hInstance, NULL);
HWND editbox=CreateWindowA("EDIT", NULL,
WS_VISIBLE | WS_CHILD | WS_BORDER | ES_LEFT,
87, 81, 150, 17,
hWnd,
(HMENU)5, hInstance, NULL);
WS_CHILD is required if you want to display the new control atop a window...
