    - copy unmanaged memory block to managed memory pointer the structures I have usually contains int, double, char, array of int, array of double, array of char, but no pointer. I am wondering if managed code can use FieldOffset to put 3 individual int into continuous memory block, why it can not put an array of integers int[3] into a continuous memory block. I have a few union structures, but I am not to worry about those yet. thanks Belinda Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

    - compatibility of commercial package API's written with Visual C++ 7 .NET with more recent release of Vis C++ We are interested in trialing a windows application that includes a toolkit consisting of API's in the form of DLL's that was written in Microsoft Visual C++ 7 .NET My question is this.. Is it reasonable to assume that I will be able to write some 'concept test' code calling those API's using a later version of Microsoft Visual C++ or will I be forced to use 7 2nd question is akin (and dependant on) the first question. If the answer to the first question is 'yes'... could I possibly use MS Visual C++ 2005 Express Edition thank you very much Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

    - Is there a way to get the width and height of text in pixels from a specific font? This sounds good, getting the textmetrics couldn't help because the font and fontsize is not considered. And textmetrix contains a ton of values for letter height but of width only max and average. I continued the survey to other things around over at MSDN and what sounded good to me was GetTextExtentPoint32, however it was a failure. I think i'v seen this feature in excel and other stuff like that. i think i'll look more into this " In addition, you could consider also the DrawText or DrawTextEx functions with DT_CALCRECT flag. " ------------------------------------------------ edit: I'm apalled by the performance of these. they all return what seems to be exactly the same and wrong size. i just feel that it has to be there, but where Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

    - VS 2005 Compile C in C99 mode? Yes, there's __FUNCDNAME__, __FUNCSIG__ and __FUNCTION__ in VC. The latter is similar to C99's __func__ but actually provides a bit more than that. While __func__ is a predefined identifier, __FUNCTION__ works much like a macro. For instance, you could create a wide character version of the function's name by using token pasting. I believe, you could just #define __func__ __FUNCTION__ and get pretty much the C99 behavior. There might be some subtle differences (e.g. __FUNCTION__ could yield different pointers), but these seem to be rather academic. -hg Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

    - How to identify the Type of Device plugged in to the PC What I need is a code that can detect the Device Type (i.e. scanner, printer, flash drive, External hard disk, external cdrom etc.) of the devices that are connected to a pc through Firewire and/or USB ports.

    - Sending Commands to any Process It's been too long since I last poked around with the specifics of click handling, but I believe you'd get a long way by sending a WM_LBUTTONDOWN followed by a WM_LBUTTONUP, at least with "normal windows". With the ovnerdrawn / handled windows you speak of, raw input may very well be used to handle varying forms of keyboard and mouse notifications. My best suggestions would be for you to snoop on whatever WM_INPUT messages arrive when you press certain key or mouse combos, then re-send those messages programatically.

    - Opengl Release vs. Debug version Hi, I wrote an opengl program using .Net 2003 in C++. When I do a debug version of the program it runs perfectly, but then when I do a release version of the program I get a black screen, even though the program compiled is exactly the same. If anybody out there knows what might cause this to happen please let me know, thanks. Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

Maybe it would be better to create a new MFC project using wizard, and then move your code to this project I hope this makes sense. I tried it but it didn't work out. Maybe it's due to my shortage of knowledge. I've posted the source code above, and if you check it out you'll find that I have called AfxSetResourceHandle() and annotated the line after finding out it doesn't work. In addition, my source code doesn't contain WinMain function and its entry point is quite different. Thanks for the reply! Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

    - Forms drawing order Well, a problem again. Ithe code I pased works almost good - It doesnt work when I open small window at first time (it hides behing main form when I clikc main form), but when I bring it back to front, then it works as it should.

    - reinterpret_cast Hi agian! I have this code now, I was using ifstream, but it was well over my head, didn't understand it. But what I'd like to do with this code is get the buf to read in 64 bits (8bytes), which is does. But I would like to output the decmial value of that interger. However it seem just to but the 8 bytes back into the txt file. How do I get it to print of the number from the buffer the interger being displayed by value Oneline, is not correct. I can't figure out what it is doing Eventually I'll get this program to read in a whole file, I was thinking of 8byte at a time, and print it off to a file. Using a while(!eof) statement, please would you let me know if that's not possible #include <stdio.h> #include <stdlib.h> int main( void ) { unsigned __int64 Oneline; char buf[ 8]; int index; FILE *fptr; if (( fptr = fopen ( "test.jpg" , "rb" ) ) == NULL ){ printf ( "Cannot open file\n" ); exit ( 1 ); } fread ( buf, 1, sizeof (buf), fptr ); fclose ( fptr ); if (( fptr = fopen ( "Kounter-report31.txt" , "w+" ) ) == NULL ) { printf ( "Cannot open file\n" ); exit ( 1 ); } fprintf(fptr, "%I64u\n" ,Oneline); fwrite ( buf, 1, sizeof (buf), fptr ); fclose ( fptr ); } Thanking you kindly for you time James Tag: Visual C++ General Draw bitmap using GDI+ Visual C++

Hi all,

  I have a MDI application in which I want to display bitmap in  view ( Base 
class is CScrollView) with Scroll bar using GDI+, later I want to mark some 
part of the image.

So plz tell me how I can draw a bitmap with Scroll bar.


Thanks and Regards

You'll have to draw the bitmap (in an onPaint or similar handler), then offset it by the position of the scrollbars. As for the marking, you will have to implement that yourself -- possibly through drawing a border or rectangle onto the displayed bitmap as the mouse is dragged above it.

Have a look at http://www.codeproject.com/vcpp/gdiplus/doodle.asp, or snoop around codeproject.com / codeguru.com for more examples.
