winapi - How to copy a picture from disk into the clipboard with win32? -


it's easy copy text clipboard win32 api, want copy picture disk (for example, d:\1.jpg) clipborad.

i search many webpages , can't find useful. please teach me how it.

and no mfc.

you can use gdi+ load image, hbitmap, , set clipboard data. gdi+ unicode only, if using old ansi functions have convert filename wide char. example in c++: 

bool copyimage(const wchar_t* filename) {     bool result = false;     gdiplus::bitmap *gdibmp = gdiplus::bitmap::fromfile(filename);     if (gdibmp)     {         hbitmap hbitmap;         gdibmp->gethbitmap(0, &hbitmap);         if (openclipboard(null))         {             emptyclipboard();             dibsection ds;             if (getobject(hbitmap, sizeof(dibsection), &ds))             {                 hdc hdc = getdc(hwnd_desktop);                 //create compatible bitmap (get ddb dib)                 hbitmap hbitmap_ddb = createdibitmap(hdc, &ds.dsbmih, cbm_init,                     ds.dsbm.bmbits, (bitmapinfo*)&ds.dsbmih, dib_rgb_colors);                 releasedc(hwnd_desktop, hdc);                 setclipboarddata(cf_bitmap, hbitmap_ddb);                 deleteobject(hbitmap_ddb);                 result = true;             }             closeclipboard();         }          //cleanup:         deleteobject(hbitmap);           delete gdibmp;                   }     return result; }

note microsoft recommends using cf_dib set bitmap clipboard data, doesn't work gdi+. example uses cf_bitmap instead.

gdi+ uses standard gdiplus.lib library. needs initialized follows:

#include <windows.h> #include <gdiplus.h>  #pragma comment(lib, "gdiplus")//visual studio specific  bool copyimage(const wchar_t* filename);  int main() {     //initialize gdiplus once:     gdiplus::gdiplusstartupinput gdiplusstartupinput;     ulong_ptr gdiplustoken;     gdiplus::gdiplusstartup(&gdiplustoken, &gdiplusstartupinput, null);      copyimage(l"d:\\1.jpg");      gdiplus::gdiplusshutdown(gdiplustoken); }

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
