Do you develop both the server and client?

I only develop the server. The client is working well with other servers and it is open source.

Okay. It is up to the developers who are working on the client to get it to synchronize with your server.

I need to get some memory information in my program

Amount of memory in computer.
Available memory.
How much memory my program currently occupies.

Anyone know how to do it or where I should look.

Thanks. It solved 2 out of 3 problems..

Still have one problem. How do I find out how much memory my program already has allocated? Like in TaskManager, where I can go and see how much memory a program takes. But I need to do it in code in runtime.

Problem Solved..

To get CurrentProcess memory usage

<br />
#include "Psapi.h"<br />
<br />
...<br />
...<br />
...<br />
HANDLE hProcess = GetCurrentProcess();<br />
PROCESS_MEMORY_COUNTERS pmc;<br />
GetProcessMemoryInfo( hProcess, &pmc, sizeof(pmc) );<br />
<br />
....<br />
....<br />

and Add 'Psapi.lib' to link settings.

huge .bss - where does it come from?

Read this before you put too much stock in those numbers:

Hi,

I have a couple of DLL's which have an "unexplained" 8MB overhead in the .data segment (virtual size 0x00800000). The data does NOT appear in the binary (so I suppose it's zero-initialized data)

Any idea how to find out where this comes from?

More Info: I have a dozen COM DLL's, 7 of them implement modules with more or less the same interface, in roughly two groups, one group has the overhead the other has not. Virtual size of .data segments in the "ok" group is around <0x5000, in the "problem" group 0x800000 + sth. <0x5000.
I cannot find anything that looks like the culprit

Map file: the relevant entries are
...
0003:00003d58 008008dcH .bss DATA
...
0003:008043fc ?_Nilrefs@?$_Tree@VCString@WTL@@U?$pair@$$CBVCString@WTL@@M@std@@U_Kfn@?$map@VCString@WTL@@MU?$less@VCString@WTL@@@std@@V?$allocator@M@4@@4@U?$less@VCString@WTL@@@4@V?$allocator@M@4@@std@@1IA 00cd73fc FWorkLib:DlgConflict.obj
0003:00804400 ?_Nil@?$_Tree@VCString@WTL@@U?$pair@$$CBVCString@WTL@@M@std@@U_Kfn@?$map@VCString@WTL@@MU?$less@VCString@WTL@@@std@@V?$allocator@M@4@@4@U?$less@VCString@WTL@@@4@V?$allocator@M@4@@std@@1PAU_Node@12@A 00cd7400 FWorkLib:DlgConflict.obj
i.e. it looks like the _Nilrefs thing claims that much size.
Funnily, even DLL#s that are not affected use FWorkLib:DlgConflict.obj

If the "text box" is a datetime control, you can use the DTM_GETSYSTEMTIME message. With MFC, this is CDateTimeCtrl::GetTime(), and the result can be stored in a CTime or COleDateTime object.

If you just have a plain edit box, use GetWindowText() to get the value, and then parse it accordingly. It'll depend on where the year is within the date.

Where are you trying to invoke OnInitialUpdate? Or are you letting MFC do it. Also, check and make sure your routine declaration matches EXACTLY. If you change and argument or a return type, it won't get executed.

Tim Smith

I'm going to patent thought. I have yet to see any prior art.

i did let mfc to do it.and i didn't change the parameter or return type.

i've look up the msdn.it said the function is called when the view is first attached to the document.but my app has no document.it is a extension dll,and the view is just one of the views of the splitterwindow.
Does that do something to my app?

Thanks DavidCrow,
I studied the website you have given. But my problem is different.

I want to read the MPEG file. I don’t know the Header format of the MPEG file. What it contains exactly.
The MPEG I have is Encrypted by some unwanted data. I want to remove it

Then you'll first need to decrypt the file before you can even attempt to read the MPEG's header.
