As was suggested before you need to create a compatible bitmap. You also need to pass the dc from the paint DC to the CreateCompatibleDC function, not the other way around. Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke

bitblt. Code snippet to help you (heavily edited and content deleted): BOOL DoChart(CallContextObj *pCallContextObj) { CDC oMemDC; CBitmap *pOldBmp; CBitmap oBmp; long lWidth = 300; long lHeight = 200; pCallContextObj->GetParameterValue("ChartWidth",&lWidth); pCallContextObj->GetParameterValue("ChartHeight",&lHeight); CRect oBmpSize(0,0,lWidth,lHeight); oMemDC.CreateCompatibleDC(NULL); int iOldMapMode = oMemDC.SetMapMode(MM_TEXT); CWindowDC dcScreen(NULL); oBmp.CreateCompatibleBitmap(&dcScreen,oBmpSize.Width(), oBmpSize.Height()); pOldBmp = oMemDC.SelectObject(&oBmp); WORD wChartType = 88; pCallContextObj->GetParameterValue("ChartType",&wChartType); BOOL bRetval = FALSE; char caHeaders[512]; strcpy(caHeaders,"Invalid Chart Type"); switch (wChartType) { case 0: bRetval = DoLineChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize); break; case 1: bRetval = DoBarChart(FALSE,pCallContextObj,&oMemDC,caHeaders,oBmpSize); break; case 2: bRetval = DoBarChart(TRUE,pCallContextObj,&oMemDC,caHeaders,oBmpSize); break; case 3: bRetval = DoOpenHiLowCloseChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize); break; case 4: bRetval = DoPieChart(pCallContextObj,&oMemDC,caHeaders,oBmpSize); break; } if (bRetval) { LPSTR cpBuf = pCallContextObj->GetOutputBufferPtr(); long lQuality = 75; pCallContextObj->GetParameterValue("ImageQuality",&lQuality); char caContentType\[256\]; long lDataSize = WriteImage(oBmp,cpBuf,pCallContextObj->GetOutputBufferSize(),caHeaders,(DWORD)lQuality); if (lDataSize > 0) { pCallContextObj->SuppressHeaders(); // pCallContextObj->GetMimeType("x.bmp",caContentType); pCallContextObj->GetMimeType("x.jpg",caContentType); sprintf(caHeaders,"Content-Type: %s%sContent-Length: %d%s%s",caContentType,cpCRLF,lDataSize,cpCRLF,cpCRLF); // write out our custom headers if (pCallContextObj->ServerSupportFunction(HSE\_REQ\_SEND\_RESPONSE\_HEADER,"200 OK",0,(LPDWORD)caHeaders) || ::GetLastError() == 10054) pCallContextObj->WriteClient((LPVOID)cpBuf,(LPDWORD)&lDataSize); \*cpBuf = 0; } else bRetval = FALSE; } oMemDC.SetMapMode(iOldMapMode); oMemDC.SelectObject(pOldBmp); oMemDC.DeleteDC();

Thanks, though I'm using CreateDialogIndirectParam and DialogBoxIndirectParam right now LPCTSTR Dutch = TEXT("Double Dutch :-)");

Well, when I wrote the thing and uploaded it, in a minute I knew the solution, It works great. The function looks like: static LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam) { if (nCode == HCBT\_CREATEWND) { LONG counter = 0; HWND hWnd = reinterpret\_cast(wParam); LPCBT\_CREATEWND lpcw = (LPCBT\_CREATEWND)lParam; LONG lpCreateParams = (LONG)lpcw->lpcs->lpCreateParams; // This makes it possible to use "API-style" windows too, where // the lpCreateParams does not point to a class if (lpCreateParams != 0 && lpcw->lpcs->hInstance == \_\_hInstance\_\_) { for (iIterator = arrUnboxedClasses.begin(); iIterator != arrUnboxedClasses.end(); iIterator++, counter++) { if (arrUnboxedClasses.at(counter) == lpCreateParams) { ::SetWindowLong(hWnd, GWL\_USERDATA, lpCreateParams); goto end; } } } } end: return CallNextHookEx(\_\_hWndsHook\_\_, nCode, wParam, lParam); } I still think that another application may not crash because I install a hook, this is not a really good design, I think. LPCTSTR Dutch = TEXT("Double Dutch :-)");

Thats NOT possible with nested controls. See for yourself add atextbox to a table cell and there noway you can set the properties via the Designer, you need to edit them directly in the HTML. DBHelper - SQL Stored Procedure Wrapper & Typed DataSet Generator for .NET

Do I need to register a manifest file or something, I really don't know whats going wrong. LPCTSTR Dutch = TEXT("Double Dutch :-)");

This thread is DAMN old, i know. But for people who actually wanna find the solution (like myself the half of day), here is the answer: XP Manifest indicates that application will use Microsoft.Windows.Common-Controls ver. 6.0.0.0 theme extensions. But it DOES NOT ensure that that the common control dynamic-link library (DLL) is loaded. So before calling something even as simple as "MessageBoxA" in the application with such embedded manifest, you should call "InitCommonControls" from "comctl32.dll".

You're right, I can find it. I looked it somewhat and made my own code doing it. I've just finished the String to Integer algorithm.int String::ToInteger(String string) { size_t index = 0; bool leadSpace = true; bool isValue = true; bool minus = false; int value = 0; try { // first scanning if the string has non-numbers while(leadSpace) { TCHAR tcRet = string.GetCharAt(index); if (((tcRet < TEXT('0')) || (tcRet > TEXT('9')) ) && (tcRet != TEXT('-')) && (tcRet != TEXT('+'))) { index++; } else { leadSpace = false; } } // scan whether the first character is equal to '-' (45) or '+' (43) TCHAR tcRet = string.GetCharAt(index); if (tcRet == TEXT('-')) { minus = true; index++; } else if (tcRet == TEXT('+')) { index++; } // OK, now a number begins, I hope, if no number is found after the minus // or plus sign, we immediatly return 0 while (isValue) { TCHAR tcRet = string.GetCharAt(index); if (tcRet >= TEXT('0') && tcRet <= TEXT('9')) { int hold = (int)tcRet - (int)TEXT('0'); value *= 10; value += hold; index++; } else { if (minus) return -value; else return value; } } } catch (Exception ex) { throw (ex); } return 0; } this is the code I'm using now to do it (if someone likes it, just use it) I'm now working on ToDouble, ToBoolean (easy!), ToUnsignedInteger, etc...

Never thought to look @ Wine ;) Heheh. Still, quite informative that code snippet, and the psuedocode one below from MSJ...which looks like it still allows for 16-bit (!) thingamadoodles. TranslateMessage allows for "preprocessing" of Virtual key messages into character messages, which are then posted to the calling thread's message queue.

My mistake. I'm talking about the VS.NET portion of the MSDN Universal Subscription. Marc Help! I'm an AI running around in someone's f*cked up universe simulator.

Thunking/converting thiscall to callback without using fancy assembler tricks, but adapter objects and C++ standard language features as described in my article Use member functions for C-style callbacks and threads - a general solution.

I know, and as I said before, it is NOT the fault of CP. I also have contacts at MS Netherlands for my school, and setting up a meeting (which goesa ironically enough about Open Source) is not really easy. (Since SuSE is prepared, and Red Hat too...) :( LPCTSTR Dutch = TEXT("Double Dutch :-)");

Well, the problem rests that I want to interact with the Windows API, so I don't think the API let's me do this (though it is a beauty) :). Sjoerd van Leent LPCTSTR Dutch = TEXT("Double Dutch :-)");

Perhaps I'm not clean enough. While the Boehm GC exists, there is no User Interface Framework nor a framework that interacts with the Windows API (for the public developer) which uses it. (If so, please respond) LPCTSTR Dutch = TEXT("Double Dutch :-)");

Try googling for "Boehm GC".

thanks for this support, if some more would post such messages, we can launch this thing. Sjoerd van Leent LPCTSTR Dutch = TEXT("Double Dutch :-)");
