[code]I tried to fill the arraylist and then clearing it, when I clicked btnFillMem, the memory increased from 607 MB to 633 MB, but when I clicked btnClearMem, the memory didn't decrease and still around 633 MB. Do you know how to clear arraylist from memory? Or in other word, do you know how to release memory usage from an arraylist?
View 5 RepliesI am using excel to store and retrieve information. I open the excel work book then close it once the action is completed. I thought it was clearing fine till i opened my Task Manager and found a ton of instances in the Task Manager. I can clear them manually but my users are not going to do that and it is cheesy to have them have to do that. I have researched this and some folks were talking about a "Marshal" method. I researched that and don't understand what it does.[code]...

unfortunately I cannot resort to C# in my current project, so I'll have to solve this without the unsafe keyword.I've got a bitmap, and I need to access the pixels and channel values directly. I'd like to go beyond Marshal.ReadByte() and Marshal.WriteByte() (and definitely beyond GetPixel and SetPixel).Is there a way to put all the pixel data of the bitmap into a Byte array that works on both 32 and 64 bit systems? I want the exact same layout as the original bitmap, so the padding for each row (if it exists) also needs to be included.Marshal doesn't seem to have something akin to:
byte[] ReadBytes(IntPtr start, int offset, int count)
Unless I totally missed it..

I have a structure in VB.NET that has a dynamic array of double as a parameter. I am passing an array of structure (GElement) to a C++ DLL. I tried converting my array of GElement into a block of unmanaged memory, it works in VB.NET but crashes in my C++ DLL. I get the same error just trying to simply pass an array of GElement to my DLL instead of a Intptr.
Here is the error
0xC0000005: Access violation reading location 0x00000004
Here is my function and structure in the DLL:
void _stdcall TestGElement(GElement* ge,long& nbge){
nbge=5;
} struct GElement {
double Step2D;
double Step3D ;

I know it is easier if the array inside the structure as an already defined constant size but that can't be the case here...
