Dangleberry11-Sep-03 1:18 Dangleberry 11-Sep-03 1:18  If you store the picture as a binary resource, then use the appropriate GIF loading mechanism on the binary resource, you should be able to obtain a HBITMAP that'll let you display the pic. Have no idea where to get the code to load the GIF file though, someone did give it to me years ago, but not sure where they got it from Alan. Re: is is posible to store GIF as resource? PengFeidu11-Sep-03 1:21 PengFeidu 11-Sep-03 1:21  Maybe CMemFile help you. pengfeidu Re: is is posible to store GIF as resource? vgrigor11-Sep-03 1:30 vgrigor 11-Sep-03 1:30  CMemFile -good Idea. Need comments how they are used by file name. ____________ Especially need to sabe - differently formatted files- but not only pictures in most expensive form. Re: is is posible to store GIF as resource? PengFeidu11-Sep-03 1:41 PengFeidu 11-Sep-03 1:41  CMemFile is the CFile-derived class But supports memory files . if you want particular content, press "CMemFile" in the index cote of MSDN. the article is detailed in msdn. dupengfei Re: is is posible to store GIF as resource? vgrigor11-Sep-03 1:47 vgrigor 11-Sep-03 1:47  I find that file can be created, but how API methods can access it? Re: is is posible to store GIF as resource? PengFeidu11-Sep-03 2:01 PengFeidu 11-Sep-03 2:01  CMemFile fMem; LPBYTE lpByte = fMem.Detach(); after create the memory file , you can use this function "Detch" to get the pointer to file. then operator it with pointer freely. dupengfei Re: is is posible to store GIF as resource?

JWood11-Sep-03 14:24 JWood 11-Sep-03 14:24  If you check out CxImage Library here on this site there http://www.codeproject.com/bitmap/cximage.asp There is an example of this in the demo. Like Dangleberry said, outside the US, GIF is subject to patents until the middle of 2004. How correctly Deactivate IPictureDisp* based control ? vgrigor11-Sep-03 0:40 vgrigor 11-Sep-03 0:40  I have control like ATLButton(MSDN) , based on IPictureDisp* property- to make picture incorporated into resource, and if I simply insert such a control into a dialog and set picture to that property - after closing dialog there is MEMORY LEAK. But if I create control by hand as code:-------------------------------------------------------------------------------- create: //------------------------------ if(m_pAtlButton ==0) m_pAtlButton = new CAtlbutton1; m_pAtlButton->Create("","",WS_VISIBLE | WS_CHILD, CRect(100,100,200,200),this,IDC_ATLBUTTON1); CDataExchange dx(this,0); CComPtr<ipicturedisp> p; USES_CONVERSION; OleLoadPicturePath( A2W("E:\\CODE\\River 1.1\\Pictures\\recuperator_alarm.jpg"), 0,0,0, IID_IPictureDisp, (void**)&p); DDX_Control(&dx, IDC_ATLBUTTON1, *m_pAtlButton); m_pAtlButton->putref_PictureStatic(p); //call by CDialog //Or so: //m_pAtlButton->put_PictureStatic(p); //------------------- delete if(m_pAtlButton ) { m_pAtlButton->DestroyWindow(); m_pAtlButton->InternalRelease(); delete m_pAtlButton;//->DestroyWindow(); m_pAtlButton =0; this->Invalidate(); this->UpdateWindow(); } //------------------------------ at control [propputref, id(8)] HRESULT PictureSecond([in]IPictureDisp* pPicture); [propput, id(8)] HRESULT PictureSecond([in]IPictureDisp* pPicture); [propget, id(8)] HRESULT PictureSecond([out, retval]IPictureDisp** ppPicture); -------------------------------------------------------------------------------- and than delete it - all works correctly. No memory leaks. What I must do that usual CDialog not cause memory leak? And where it happen? Thanks you. RGB <--> YUV Pawel Olszewski11-Sep-03 0:29 Pawel Olszewski 11-Sep-03 0:29  Hi All! I have picture in qcif format (176x144) i have it's luminance values and chrominance also. (YUV 4:2 ) Now question does anybody know how to conwert those YUV values to RGB? assuming i have such structure: <br /> typedef struct qcif<br /> {<br /> char Y[144][176];<br /> char U[72][88];<br /> char V[72][88]; // unused since it's 4:2:0 YUV<br /> }<br /> please help me, i was searching on google but without any success Take care Pawel Olszewski P.S. i have found RGB->4:2:2 and RGB-->4:2 converter: rgb_422 & rgb_420 Re: RGB &lt;--&gt; YUV selfk11-Sep-03 1:27 selfk 11-Sep-03 1:27  there is a tool to grap webcam pictures. name is vgrabbj for linux. you must search for it in google. then download the source code. in the source code is a file ccvt_c.c. this file has functions to convert YUV<-->RGB. it is c code . good luck !! Re: RGB &lt;--&gt; YUV Pawel Olszewski11-Sep-03 2:28 Pawel Olszewski 11-Sep-03 2:28  Thank You selfk! It was really clear code, i haven't even 1 warning etc. Thanks once again Ques related to snmp SatyaDY11-Sep-03 0:19 SatyaDY 11-Sep-03 0:19  Hi guys, I am trying to get status of my remote network equipment, through snmp. I am trying to convert the oid to AsnObject Identifier using the following call. if (!SnmpMgrStrToOid(Oid, &reqObject)) AfxMessageBox("SnmpMgrStrToOid failure"); The oid I am passing is char Oid[255]=".1.3.6.1.2.1.2.2.1.8"; I added '.' at the end for a second trail, still I am always getting failure. What wrong with my code ?? Thanks in advance, Satya How to put an icon in .ico file on a toolbar button? gumber11-Sep-03 0:05 gumber 11-Sep-03 0:05  Hi there, I have a number of .ico files, each having an icon in it. I want to build a toolbar containing buttons, each having an icon from one of these .ico files. Kindly tell me how to do this. Regards Gaurav Gumber Re: How to put an icon in .ico file on a toolbar button? Dominik Reichl11-Sep-03 0:19 Dominik Reichl 11-Sep-03 0:19  I would do it the following way: 1) Load the icon using the LoadIcon API function. 2) Use the GetIconInfo API function to get a ICONINFO structure which contains a HBITMAP handle to the color bitmap. 3) Set the toolbar-button's bitmap using the MFC CToolBar::SetBitmap function. Hope that helps Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? (doesn't work on NT) No activation of window Bjarne Jørgensen11-Sep-03 0:03 Bjarne Jørgensen 11-Sep-03 0:03  I have used some of the ideas from Nishant S's article "Some handy dialog box tricks, tips and workarounds" sections "How to steal focus on 2K/XP" and "Making your dialog stay on top" What: I want a dialog to be shown for a number of seconds, "stealing" mouse input (using ClipCursor) and thereafter releasing. This is working now, but my problem is that the previous foreground window is not activated by windows (Using W2K). A solution could be to save the current foreground pointer and after releasing the mouse, then use the pointer m_pPrevious->SetForegroundWindow(); This works (most of the time) but the help for GetForegroundWindow() warns that it is a temp pointer. And in speciel cases that has shown to be true. How do I ensure re-activation of the previous "foreground window"?? Re: No activation of window Dominik Reichl11-Sep-03 0:23 Dominik Reichl 11-Sep-03 0:23  As far as I can see, this warning is only mentioned in the MFC CWnd::GetForegroundWindow function... so why not use the Win32 API function GetForegroundWindow directly? Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? (doesn't work on NT) Re: No activation of window Bjarne Jørgensen11-Sep-03 0:59 Bjarne Jørgensen 11-Sep-03 0:59  Thanks This is worth a look... I called GetForegroundWindow in my dialog class and didn't know of the other .( I guess I could use ::IsWindow() to check if this handle still is valid Libraries Zizilamoroso10-Sep-03 23:42 Zizilamoroso 10-Sep-03 23:42  I'm not used to create my own libraries in C++ (Did it dozens of times in java), but now I want to create one implementing easy to use logging functions. MyLog.lib is a win32 static library. It works fine when linked from an ordinary win32 console application. But, when trying to implement it in an MFC application, I get numerous linking errors. Did I forget something? Is it possible to link to a win32 library from an MFC app? tnx using: [VISUAL STUDIO 6.0 sp5] [WIN98/2] Re: Libraries jhwurmbach10-Sep-03 23:52 jhwurmbach 10-Sep-03 23:52  Zizilamoroso wrote: I get numerous linking errors.

Please check your project settings: You need to have *ALL* projects set to using either "multithreaded" *OR* "multithreaded dll". Maybe you need to make both versions of your library for use in different projects. Who is 'General Failure'? And why is he reading my harddisk?!? Re: Libraries Zizilamoroso11-Sep-03 2:08 Zizilamoroso 11-Sep-03 2:08  They're both "debug multithreadeded", but the mfc app was "debug multithreaded dll". The " dll" piece of the string fell out of the combobox' window bounds )) So, that's why I didn't saw this one. I demand larger comboboxes in VC!!! ) lol tnx jhwurmbach using: [VISUAL STUDIO 6.0 sp5] [WIN98/2] Re: Libraries jhwurmbach11-Sep-03 2:10 jhwurmbach 11-Sep-03 2:10  Now it works? Great!
