asp.net - AutoPost capture what caused it. -


i have following code in .aspx file:

    <asp:textbox id="txtsearch" runat="server" width="278px"></asp:textbox>     <asp:button id="btnsearch" runat="server" text="search" autopostback="true" />

when click on btnsearch button autopostback.

what goal if btnsearch clicked, capture value of txtsearch or else not

how code such if btnsearch clicked on autopost can flag it.

first, button does not have autopostback property. posts always.

second, can handle it's click event , read txtsearch.text property:

<asp:textbox id="txtsearch" runat="server" width="278px"></asp:textbox> <asp:button id="btnsearch" runat="server" text="search" onclick="btnsearch_click" />

codebehind:

protected void btnsearch_click(object sender, eventargs e) {     string search = txtsearch.text;     // ... }

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
