Would you please tell me why the progress bar in the outside don't go after a cycle? Is a progress bar can not be repeated load? It's can load a code:

M_progress. SetRange (0, 100);

M_progress. SetPos (0);
M_progress. Invalidate ();

int i=1;
for (; I & lt;=100; I++)
{
M_progress. SetPos (I);
}
How to implement a progress bar repeatedly reload?

M_progress. Invalidate ();
Put in the for

Put that in the for loop? I didn't write the outermost layers of the loop?

M_progress. SetRange (0, 100);

While (1)
{
M_progress. Invalidate ();
M_progress. SetPos (0);
int i=1;
for (; I & lt;=100; I++)
{
M_progress. SetPos (I);
}

}

Should not be like this? Why don't the progress bar move?

CodePudding user response:

M_progress. SetPos (I); After reading to redraw
M_progress. Invalidate ();

CodePudding user response:

Add
M_progress. SetPos (I); After reading to redraw
M_progress. Invalidate ();
M_progress. UpdateWindow ();//can't update the interface in the loop!

CodePudding user response:

I set the progress bar is usually don't need to update,
As long as set up setpos location will update the progress bar himself,

CodePudding user response:

Loop blocked message ring, you can RedrawWindow mandatory update

 
for(int i=0; i<=100; I++) 
{
PCtrl - & gt; SetPos (I); 
PCtrl - & gt; RedrawWindow (); 
}

Blocked, had better be message processing progress inside,
