更新WINAPI中的文本框项目

Question

I created a textbox with following code. It is placed under WM_COMMAND of WNDPROC function.

htextbox=CreateWindowEx(WS_EX_CLIENTEDGE,TEXT("Edit"), TEXT("test"), WS_CHILD \
                         | WS_VISIBLE | WS_BORDER, 100, 20, 140, 20, hWnd, NULL, NULL, NULL);

I want to update the element "test" written in the textbox when I receive: DT_MSG which is a message I receive from another application and the DT_MSG contains the item I want to write in the textbox. suppose the item I get is number say

int a=dtmsg.somenumber

Do I have to delete the above htextbox window and again create new textbox window with updated value or is there alternative and I can simply update "test" item in the same text box?

Answer 1

您可以使用Win32 API SetWindowText更改编辑控件的文本

Answer 2

我想你可以这样做：

SetWindowText(htextbox, TEXT("new text"));
