c++ - Button control takes some time to disable in dialog box -

-

I'm trying to take some long action in the dialog box from my mainthread. During that time I wanted to disable some control. I used EnableWindow (FALSE) for each control to disable it. But all other control except button control (such as slider control, CMFCIDitbro control, combo box control) are fully disabled before processing. But buttons are taking more time to disable control, they are almost finished when the operation is finished. As soon as I call EnableWindow (FALSE), were not disabling button controls? Why is it taking time to disable it?

You need to completely perform background tasks in another thread, and UI / control can be used by another thread You should use PostMessage , if the call does not work directly on EnableWindow Setfocus , for example, does not work with a different thread

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
