ftp://ftp.microsoft.com/PSS/Tools/Developer%20Support Tools/WINDBG 4.0.18/
dbg_x86.exe
and use CFtpConnection class function : GetFile, OpenFile, SetCurrentDirectory
Thanks

This worked for me:
CInternetSession ISession;
CFtpConnection *pFTPConnect = NULL;
BOOL bContinue;
pFTPConnect = ISession.GetFtpConnection(_T("ftp.microsoft.com"), _T("anonymous"), _T("name@company.com"));
bContinue = pFTPConnect->SetCurrentDirectory(_T("/PSS"));
if (bContinue)
bContinue = pFTPConnect->SetCurrentDirectory(_T("Tools"));
if (bContinue)
bContinue = pFTPConnect->SetCurrentDirectory(_T("Developer Support Tools"));
if (bContinue)
bContinue = pFTPConnect->SetCurrentDirectory(_T("WINDBG 4.0.18"));
if (bContinue)
pFTPConnect->GetFile(_T("dbg_x86.exe"), _T("c:\\dbg_x86.exe"));
if (NULL != pFTPConnect)
pFTPConnect->Close();
delete pFTPConnect;You'll need to put in the necessary error checking.

1)If your code ok for "ftp://ftp.microsoft.com/deskapps/games/public/cc3/Screenshots/Stalingrad zoom out.bmp"?
The file name have space!!!
2)_T() is necessary? why?
3) How to use CFtpConnection ::OpenFile()/CInternetFile::Read()/CInternetFile::Write()? Why not use CFtpConnection::GetFile()
Thanks!!!

I tried to disable the "Save" toolbutton on the toolbar.
I tried to set the state of "Save" toolbutton to disabled mode by specifying
TBSTATE_INDETERMINATE . But this doesnt disable the save toolbutton.
TBBUTTONINFO buttonInfo;
buttonInfo.cbSize = sizeof( TBBUTTONINFO );
buttonInfo.dwMask = TBIF_COMMAND;
buttonInfo.fsState = TBSTATE_INDETERMINATE ;
m_wndToolBar.GetToolBarCtrl().SetButtonInfo(ID2_FILE_SAVE, &buttonInfo);
Let me know the exact procedure to do the same.
Thanx in advance

Check out ON_UPDATE_COMMAND_UI(ID2_FILE_SAVE, ...). In the handler function, you can easily enable/disable the Save button.

Hi,
I have a query on pointer arithmetic.
I declared a structure like this
struct myStruct{
int index;
char sz[124];
};
Inside the main(), I created 10000 objects of the structure and assigned it to a pointer variable.
myStruct* obj = new myStruct[10001];
memset( obj,0,sizeof(myStruct) * 10005);
myStruct* obj1 = obj;
long l1 = 0;
for( long l=0;l<100000000;l++)
{
obj++;
l1 += obj->index; //just an addition so that compiler wont remove the previous line
if( i % 10000 == 0 ){
obj = obj1;
l1 = 0; //reseting the values;
}
}
When I executed this, it took me 8 sec.
But if I reduce the size of myStruct to 64, it takes only 4 sec.
ie.
struct myStruct{
int index;
char sz[60];
};
and again reducing the size to 32, it takes only 2 secs.
I examined the assembly code which was generated by Disassembly, and the only change was in the 2nd line
obj++;
mov edx,dword ptr [ebp-14h]
add edx,100h
mov dword ptr [ebp-14h],edx
thats in
add edx,100h ( 256 b ) time : 8sec
add edx,20h ( 32 b ) time : 2sec
Can anybody pl. give me an explanation for this behaviour.
I was able to reproduce this behaviour in Unix also....
Thanks and Regards

This is an effect of L1 cache. You did not mention the CPU you were using. I assume it was a P4. The L1 access line size is 64 bytes if my memory serves me right. If there are no alignment issues(your compiler often does a good job at this), the smaller size the structure is the more effective for a single L1 line access. Nowadays, people often talk about structure of arrary (SoA), that address such issues....

Here you actually create 10.001 structs and initialize 10.005! This is very wrong!

}
A couple of questions on this piece of code:
<list> Why the dummy addition (l1 += obj->index;) The compiler won't remove the line, since you use the object further down your code!
Why such a long loop?
Your loop does nothing usefull, why?
To get to an answer, I honestly don't think that the long loop is your problem. I think the problem lies with memset(). Let me explain: your execution time drops liniear with the size of the struct. So the size of the array decreases also liniear. (You halve the size of the stuct, so the size of the array is also halved.) So the amount of memory that memset() has to fill is also halved!
Besides that, your loop executes 100 million times! Don't expect that to finish in a few ms..

I am trying to write a function that copies a jpg or a gif to the clipboard, when I pass the path to it.
ie
jpgclip("C:\test.jpg")
Can anybody help me?

Have you looked at SetClipboardData()?

Yes I have looked at this function, but could use a few pointers on how to use it. I know I can send a bmp to the clipboard with this, but is there anything I need to know when sending jpg or gif?

Hi Everybody
I am doing a project in image processing using MFC.
Could some one tell how to save a bitmap (1 bit,4,8,24 bits respectively).
Thanks in advance.
|
|
|
|
|
No 16 bit ?
If you're using GDI+, read my articles on the subject. Otherwise, I guess either save to bitmap only ( the format is well documented and simple ), or find some other library to use.

Hi I am doing a project in image processing using MFC. GetBitmapBits() stores the pixel value in a BYTE array. It works fine with 8 bits bitmap, but when working with 4 bits bitmap, it combines 2 pixel values and stores in the BYTE array.
How to overcome this problem
|
|
|
|
|
Use && and || to combine and mask values, instead of + or =. For example, FF && F0 == F0. If you take an 8 bit number and set it to equal itself && 15, you get only the low four bits, && 240 gives you the high four. In that way, you can set one pixel to zero. Then if you want to set the pixel in the low four bits, you just put oldVal || newval, that copies it in. to copy into the high four, do this: oldval || ( newVal << 4). this shifts the values up four bits first. To just set two pixels do this (pixelLeft << 4) + pixelRight. You can use plus here, because you're replacing both values.

hiho@ll
i try to change the source of a browser helper object, which makes some strange things (like opening google, if i want to open a .js file  )
my question (because i don't really know much about helper objects) how can i debug the object?
it is visible as an Add on in Inernet Explorer
and when i try to debug the bho visual studio .net asks which application holds the debug information
i tried using Internet Explorer, but didn't work
the helper object is a dll
maybe the question should be how to debug a dll?
thx@ll

I am building the shell extension for 64 bit windows XP. While compiling the 32 bit shell extension code (working well on windows xp 32 bit) on visual studio.NET 2003 on 64 bit build environment getting the following errors:
myapp.obj : error LNK2001: unresolved external symbol _CLSID_BkgndCtxMenuExt
myapp.obj : error LNK2019: unresolved external symbol _LIBID_DIRBKGNDEXTLib referenced in function _DllMain@12
myapp.obj : error LNK2001: unresolved external symbol _IID_IBkgndCtxMenuExt
anybody please help me on this..
or is there any way to make 32 bit shell extension dll to work on 64 bit windows xp. on windows site its written that 32 shell extension will not work on 64 bit windows..
So what are the interfaces for shell extention in 64 bit windows XP.
thanks
