for large images, you can use the same technology as the TIFF image format, they can use tiles to split a large file into smaller sections; for example, you could have a tile size of 1000x1000 and load/display the appropriate tile ( and its 8 neighbours ).

 For some reason, I am not able to find any code (c++) on how to print from a Windows Form that has a richTextBox and a print button. Does any one point me in the right direction for some constructor code to input in the following:
private: System::Void button4_Click(System::Object * sender, System::EventArgs * e)
{
}
private: System::Void printDocument1_PrintPage(System::Object * sender, System::Drawing::Printing::PrintPageEventArgs * e)
{
}

I am learning Visual C++ .NET from a book. I made a dialogue and I don't know how to get the combo box list data values (i.e. Food, Clothes, Toys) to display. I put the values (Food;Clothes;Toys) in the data portion of the properties tab, and even made the relevant function (i.e. OnBnClick...), but I don't know how to get the list to display. Any help would be appreciated.
Thanks.

The following is a list of files that I tried to include....
#include <string.h>

Hi
How can I access the bitmap pixel data DIRECTLY?
I dont want to use the GetBitmapBits and SetBitmapBits functions because they copy memory to another location.
I want to determine where the pixel data of a CBitmap Object are, and having a pointer on them and change them directly without having to "copy from" and "copy to" every time.
Thanx All

you might try using a DIBSection, which can act like an HBITMAP, but is actually a normal DIB - you can access the pixels by normal pointer arithmetic, etc.

By knowing the BMP file format, you can get access to any part of it.

If older platforms are an issue, you might want to consider using SHGetFolderPath(), which is a superset of SHGetSpecialFolderPath().

Does this work? Surely you have to allocate a buffer to pass to SHGetSpecialFolderPath? Wouldn't you have to call GetBufferSetLength and ReleaseBuffer either side of the call to SHGetSpecialFolderPath?

Not as it is currently presented.

Um. I don't know of an API but on my system (Windows XP SP2) the Recycle Bin is at C:\Recycled. (I think this is a real folder, not a shell folder, because I can access it through Command Prompt.) There must be a GetShellFolder API or something like that, or you could probably find it in the Registry somewheres.
|
|
|
|
|
That's right, it's not him but her
Well,I cant use that API (SHGetSpecialFolderPath) as it says 'If a virtual folder is specified, this function will fail' n RecycleBin is the virtual folder...Actaully not even folder, it's a file....I will look into it. Thanks to U all for giving the direction.
Bye

The following code:
int i = 0;
cout << i++ << i;
why does it output 00?
