Re: What is the handle count for a process in windows?

`HandleCount` property of a process refers to the number of operating system handles opened by that process. I suggest you ask such questions pertaining to .NET stuff in the .NET Framework Forum. Nobody can give you wiser advice than yourself. - Cicero ப்ரம்மா

Why is that a .net specific question ? The original poster did not mentionned the `HandleCount` property at all in his post. Maximilien Lincourt Your Head A Splode - Strong Bad

Hi The Handle count for a process is the total of handles used: Thread, opened files, events. I think u know that the function to get HC is GetProcessHandleCount. U have to be carefully if your app have HC that never decreases Regards David Leyva

Thanks alot for your replies... Handle count for a process is limited to 10000 and it can be increased to 18000 (max limit). But I can see different process on my machine (like explorer.exe) having handle count greater than 18000. How that process is running properly even when handle count has increase dramactically?

Creating .ico file from HICON

neilsolent

2:22 11 Jan '07

In a previous post I was attempting to "serialize" an HICON, i.e. save it as a blob in a file or database: the opposite operation to the ExtractIcon() operation. I have since learned how to do this (see routine below).

BUT now my problem is, this routine loses color information. When the routine is run against a true-color icon, and the buffer is saved as a .ico file, and the .ico file is reloaded with ExtractIcon(), the resulting icon has reduced to 256 colors.

I think this must be a limitation of OleCreatePictureIndirect(). How can I fix my routine?

------------------------------------------------

void SerializeIcon(const HICON icon, DWORD* size, BYTE** data)
{
     LPPICTURE pPicture;
     PICTDESC   rPD;
     rPD.cbSizeofstruct = sizeof(PICTDESC);
     rPD.picType = PICTYPE_ICON;
     rPD.icon.hicon = icon;
     IStream* pStream = NULL;
     HGLOBAL   hMem = NULL;
     BYTE* pMem = NULL;
     long lActual;

     OleCreatePictureIndirect(&rPD, IID_IPicture, FALSE, (void**) &pPicture);
     CreateStreamOnHGlobal(0, TRUE, &pStream);
     pPicture->SaveAsFile(pStream, TRUE, &lActual);
     pPicture->Release();
     GetHGlobalFromStream(pStream, &hMem);
     pMem = (BYTE*) GlobalLock(hMem);
     *size = GlobalSize(hMem);
     *data = (BYTE*) malloc(*size);
     CopyMemory(*data, pMem, *size);
     GlobalUnlock(hMem);
     GlobalFree(hMem);
}

What's wrong.... [modified]

The below code sorts a matrix diagonally. Does it, but at the end it's throwing an "illegal" may be a bad access error. Why ? int main(int argc, char* argv[]) { int A[5][5];int i;int j; int temp; int c,flag; } input : 1-1-1 2-2-2 3-3-3 output: 1-2-3 1-2-3 1-2-3 -- modified at 6:02 Friday 12th January, 2007 * *

You are accessing declared array with invalid index.
int A[5][5]; should be accessed only from A[0][0] to A[4][4] where as you are accessing it through A[1][1] to A[5][5]

Astricks wrote:
for (i = 1;i<=5;i++) {

You should modify this to,

for (int i = 0 ; i <5 ; i++)

at all places you have done mistake.

C/C++ arrays are 0-based, i.e. if you declare:

  int a[5];

then you have the following items:

  a[0], a[1], a[2], a[3], a[4];

on the other hand, a[5], is out-of-bounds.

so the correct iteration will be

   for (i = 0;i<5;i++)
     a[i]= (whatever);

This will surely work, but the poor guy will never come to know what is wrong with his approach! I think thats the reason for you being voted down.

It was a quick-fix , But I said that to indicate the error is about array-out-of-bounds. The 1 voted would have missed my point. ... anyway thanks Code-Frog:So if this is Pumpkinhead. Time for him to run and hide. It's an interesting thought really.

I decided to add my 1 to the vote, because 0 was not a choice. You received a 1 vote because you did not provide an answer to the question. If the person asking the question understood your [joke] answer then they would not have needed to ask it in the first place.

Sigh | :sigh:

Sorry, but the idea is to help and not make fun of the person asking the question.
