How can I search for a string by columns in the listview using FindItem.
Thanks

Hmm, I think you might have to use GetItemText() instead.

I wrote the following program to test what I think is a bug in the implementation of VC++ 6 templates. For some reason the first call's parameters are ignored and the second call is repeated twice.
<br />
#include "stdafx.h"<br />
#include <stdio.h><br />
<br />
template<class DATAType,DATAType data>Test()<br />
{<br />
printf("Sizeof DATAType %d\n",sizeof(data));<br />
printf("Data = %d\n",data);<br />
}<br />
<br />
int main(int argc, char* argv[])<br />
{<br />
Test<char,0>();<br />
Test<int,1>();<br />
return 0;<br />
}<br />
The output is:
Sizeof DATAType 4
Data = 1
Sizeof DATAType 4
Data = 1
I had a friend compile this on g++ and it worked as expected.
Sizeof DATAType 1
Data = 0
Sizeof DATAType 4
Data = 1

and if you reverse the order of the calls, it uses the char version of the function twice.
cool. 
definitely looks like a bug, to me.

A quick fix on this is to pass data as a parameter to the function instead of a template parameter.

This is a well-known VC++ bug. The compiler is unable to deduce the template parameters unless they're present in some form in the arguments for the function. Try the following workaround (I don't have my VS handy, but I'm reasonably sure it works):
#include "stdafx.h"
#include <stdio.h>
template<class DATAType,DATAType data>Test(DATAType* dummy=0)
{
printf("Sizeof DATAType %d\n",sizeof(data));
printf("Data = %d\n",data);
}
int main(int argc, char* argv[])
{
Test<char,0>();
Test<int,1>();
return 0;
}

How can i display an image stored in the resources in the application in an HTML File which is displayed in a CDHtmldialog ???
I would like also not to have to specify the name of the application, if this is possible.
Thanks.

In your res file you need a folder resource named "GIFS".
Then add your image to the project in that folder and name it with quotes:
"MyImage.gif"
Then in the html page refer to it like you normally would in any html file:
background="GIFS/MyImage.gif" (as an example for using it as a background)

Hi,
I get the following runtime error:An attempt was made to access an unnamed file past its end.
With this code where i try to open a textfile and put them in a stringarray.
<br />
CFile cfFile;<br />
<br />
cfFile.Open(dlg.GetPathName(), CFile::modeRead);<br />
<br />
CArchive ar (&cfFile, CArchive::load);
<br />
CStringArray test;<br />
test.Serialize(ar);
Thanks for helping!
Willem

You may want to first serialize the size of the CStringArray, followed by each CString element. See "Serializing a homogenous collection class" in this[^] article

hello,
i have another problem with child window, when i want to allow resizing i display border and when i want to prevent resizing i hide border.
now i do this to show Sizable Border:
pChild->ModifyStyle(0 ,WS_SIZEBOX ,SWP_NOSIZE | SWP_NOMOVE |SWP_SHOWWINDOW );
pChild->SetWindowPos(NULL, 0, 0, 0,0,
SWP_FRAMECHANGED |
SWP_NOMOVE | SWP_NOSIZE |
SWP_NOZORDER);
before do this i have scrolled my view with :
ScrollWindow(-posHorz,-PosVer);
my problem is when i want to show the border the view do a "ScrollTo (0,0)" ! i put "SWP_NOMOVE " in the SetWindowPos my child window don't move and why my view repositioned to (0,0) ??
i have try to remove SWP_FRAMECHANGED in the SetWindowPos and my view don't move but sizable borders aren't show!
If you know how to add sizable border and remove them easily ...
Excuse me for very bad english

Hail everyone,
I wonder, what gonna happen with STL container, let's say vector, if there is no memory for add new element? Method push_back returns nothing. In source code of vector I was able to find only 2 exceptions, _Xlen (length_error) and _Xran (out_of_range), but nothing else.
I'm not very familiar with STL, so any help is appreciated.
Thanks in advance.

Here are two excellent STL references.

try()
catch(...) // Catch any exceptions.

in: BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
Is there a limitation to size the MainFrame?
The following code-snippet works up to: int sz=7, but not with sz=8. Why?
int ySize=::GetSystemMetrics(SM_CYFULLSCREEN);
int xSize=::GetSystemMetrics(SM_CXFULLSCREEN);
cs.cy = ySize*sz/10;
cs.cx = xSize*sz/10;
cs.x=(xSize-cs.cx)/2;
cs.y=(ySize-cs.cy)/2;
return CFrameWnd::PreCreateWindow(cs);

I've just tested it and it works with sz == 10 as well.
You may send me a sample project if you wish (mail@BartoszBien.com).

If it is a problem related to CFormView (which is inherited from CScrollView), check if CScrollView::ResizeParentToFit is not called where it should not be. Hasn't tested it, but this may be the case.

Hello,
I have some queries
1. Is it possible to directly access Video RAM from User Application?
2. If not, How to read/write data directly to Video RAM ?
When searched, I found that certain IOCTLs ( like IOCTL_VIDEO_MAP_VIDEO_MEMORY ) available for Video RAM access. But It seems that these IOCTL are being used by the video driver. Can we have access to these IOCTLs and How?
Can you provide some clue as to how we can go ahead.
Regards
Sandeep

You can use DirectDraw to get access to the video memory! Just create a primary DirectDraw surface!

Hello!!
Thank you for your reply.
I have one more question.
Does DirectDraw allow the application to get the whole of the VRAM or just a part of it? Can the full VRAM be tested by writing data to it and then reading it back?
Sandeep

I think yes, but I don't know exactly!
You can access the whole video memory, that you will see on your monitor screen!
But most graphic-cards have more momory and you can allocate some memory directly in the graphic-card memory!

Thank you for your answer.
I am now able to get the total video memory which is free and total video memory in the system by using function IDirectDraw::GetCaps().
I am now able to get the pointer of the surface by using DDSURFACEDESC2 structure and IDirectDrawSurface::Lock(). I have locked the surface using the function IDirectDrawSurface::Lock(), and then went on to write data in the surface till total memory. i.e. I am filling the total video memory with my data. The data is also seen on the screen. But after the screen is completely filled, the screen can be refreshed again by pressing alt+tab and again ALT+TAB (or if the screen is refreshed by some other event). My question is if I have locked the surface how does the screen get refreshed?
I have written the data in blocks of 4 KB.
I am reading the data back and then comparing it. If I increase the size of data to be written from 4K to 5K then my compare fails. Even if I increase the data size to 8k (to see if it has to do something with page size) then too, the compare fails..
Can anyone tell me why 4096 so special?
I also need advise on feasibility of following:
While writing data on whole of VRAM can I show the data written on anypart of VRAM on the screen in a window?
Can anyone help me out?
Regards,
Sandeep
