Hello all,
I've recently made a source-code navigater (Explorer look-alike, MFC application), on which one can doubleclick on a file. For source-code files, these files will then be opened in Microsoft Developer Studio (version 6).
My problem
----------
Sometimes the view of MSDEV is corrupted by contents of my MFC-application. When minimize and maximize MS-DEV, the view is correct again.
So actually I need to refresh the MSDEV environment, after opening a file from external application (my application).
Question 
--------
How can I make MSDEV refreshing the view from an other application?
Many thanks,
EiSl

Hi,
I want to sort items in a CListCtrl. However, the sorting is not according to the first column. For example, when the user clicks on another column in the header, the list should be sorted according to that column.
I tried many methods, but I wasnt successful. I am waiting for your helps.
Thank you for any helps in advance
regards
Mustafa Demirhan

I don't know of an 'in list' solution - I do it by keeping the data in a structured array, then grab the button that has been clicked over and sorting the array by that 'colomn' values, then empty and reinsert. I remember using flexgrid once and it did it a whole lot easier, but was it's own world of grief in other areas...

Do a search on this forum for:
Sorting data in CListCtrl columns
I asked the same question. Let me know when you are done with the sorting implementation.

I try to create and show a bitmap based on one short array.No error occours during compile,but the bitmap just don't show on the view.
My code as follow:
void CReadfile1View::DrawDIBSection(HDC hDC , int xDest,int yDest,int w, int h,signed short*image)
{
BITMAPINFOHEADER *bih=0;
// HDC hDC=0;
HBITMAP hbm;
void *bits;
try
{ // allocate room for BITMAPINFOHEADER and color mask's
if(!(bih = (BITMAPINFOHEADER*)malloc(sizeof(BITMAPINFOHEADER))))
throw 0;
ZeroMemory(bih,sizeof(BITMAPINFOHEADER));
bih->biSize = sizeof(BITMAPINFOHEADER);
bih->biWidth = w; // .
bih->biHeight = h; // match array-size
bih->biPlanes = 1;
bih->biBitCount = 16;
bih->biCompression = BI_RGB; // we use 5:5:5 format
bih->biSizeImage = bih->biWidth * 2 * bih->biHeight;
if(!(hDC = ::GetDC(0))) throw 0; // create the 16-bit DIBSECTION
if(!(hbm = ::CreateDIBSection(hDC,(BITMAPINFO*)bih,DIB_RGB_COLORS,&bits,0,0))) //
throw 0; // get the array into the DIBSECTION
if(::SetDIBits(hDC,hbm,0,h,image,(BITMAPINFO*)bih, DIB_RGB_COLORS) != h)
throw 0;
}
catch(...)
{
// cout<<"unknown type of exception throw"<<'\n';
}
HDC hDCMem=::CreateCompatibleDC(hDC);
HGDIOBJ hBmpOld=::SelectObject(hDCMem,hbm);
BitBlt(hDC,xDest,yDest,bih->biWidth,bih->biHeight,hDCMem,0,0,SRCCOPY);
::SelectObject(hDCMem, hBmpOld);
::DeleteDC(hDCMem);
if(hDC) ::ReleaseDC(0,hDC);
if(bih) free(bih);
}
void CReadfile1View::OnDraw(CDC* pDC)
{
CReadfile1Doc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
DrawDIBSection(*pDC,10,10,WIDTH,HEIGHT,pDoc->Image[0]);
}
Who can tell me why it don't works and how to improve?!
thanx!

Hi,
I didn't have much time to check your code completely, but I think the source line:
if(!(hDC = ::GetDC(0))) throw 0; // create the 16-bit DIBSECTION
is incorrect.
You re-initialize the local parameter hDC, which was sent by the call to your DrawDIBSection(..) function in the OnDraw method. It will be set to a DC for the desktop, by ::GetDC(0).
This hDC is used for the BitBlt(..) command later.
Not a sollution, but just a hint...

Hi All !!
I've stupid problem !!! It make me crazy 
I want to use WinAPI struct ALTTABINFO
this struct is contained in <winuser.h>
but no way to use this struct because compiler performs an output:
error C2065: 'ALTTABINFO' : undeclared identifier
for example
//#include <winuser.h> //but I must include windows.h, look in help
#include<windows.h>
void main(void)
{
ALTTABINFO myInfo;// error!! why???
.....
}
Best regards VitSoft

If you do not have MSDN, get it and get it quick, you can't possible write windows programs without it (I have but that was many moons ago).
The ALTTABINFO structure contains status information for the application-switching (ALT+TAB) window.
typedef struct tagALTTABINFO {
DWORD cbSize;
int cItems;
int cColumns;
int cRows;
int iColFocus;
int iRowFocus;
int cxItem;
int cyItem;
POINT ptStart;
} ALTTABINFO, *PALTTABINFO, *LPALTTABINFO;
Members
cbSize
Specifies the size, in bytes, of the structure.
cItems
Specifies the number of items in the window.
cColumns
Specifies the number of columns in the window.
cRows
Specifies the number of rows in the window.
iColFocus
Specifies the column of the item that has the focus.
iRowFocus
Specifies the row of the item that has the focus.
cxItem
Specifies the width of each icon in the application-switching window.
cyItem
Specifies the height of each icon in the application-switching window.
ptStart
Specifies the top-left corner of the first icon.
Requirements
Windows NT/2000 or later: Requires Windows NT 4.0 SP6 or later.
Windows 95/98/Me: Requires Windows 98 or later.
Header: Declared in Winuser.h; include Windows.h.

Hi !!!
Thanks !!
I've MSDN lib,I know it possible to redefine this struct, but when you want use GetAltTabInfo(..) function
you have the same problem.
Why compiler don't know about this function or struct ?
error C2065: 'GetAltTabInfo' : undeclared identifier
I'm a long time work with VC, but it's first time when i have problem like this ;(
Thanks and Good Luck

If you look in winuser.h, you'll see the ALTTABINFO declaration is wrapped in an #if (WINVER >= 0x0500) block. You'll need to #define WINVER 0x0500 before your #include statements.

I need to change the MSysObjects attributes to read only thru VC.
I will be able to read tables info if I could do that. By default, MSysObjects cannot be read. I can change the setting thru Access 2000 but I want to do it thru VC.
Help!

Is there a function that will tell me if
Day Light Savings is turned on and if an OS is
running in summer or winter

I think the CRT variable _daylight indicates whether daylight savings time is in effect. The docs aren't exactly crystal clear, though.

Thanks for the speedy response Mike,
Yes you are right !
but its now proving a devil to test for
I'll implement it anyway as its several months before DST comes into effect here, To see if it works correctly.

I am looking for a fast algorithm for outputing the co-ordinates of points along an ellipse, given the bounding rectangle.
Basically as the Ellipse drawing function only that it outputs the co-ordinates of the pixels rather than drawing them.
Any suggestions would be gratefully received.
Happy programming!!

This is just quick and dirty code (written straight in an untested). This code assumes the definition of things like point2d (it's a floating point 2d point) and pi. The maths is pretty simple trigonometry, so if you have any trouble go to the library. Here goes:
<br />
point2d *GetEllipsePoints(float height, float width, point2d center, long divisions)<br />
{<br />
point2d *theList = new point2d[divisions];<br />
<br />
for (long i = 0; i < divisions; i++)<br />
{<br />
theList[i].x = cos(((float)i/(float)divisions) * pi / 180.0f)*width*0.5;<br />
theList[i].y = sin(((float)i/(float)divisions) * pi / 180.0f)*height*0.5;<br />
}<br />
<br />
return theList;<br />
}<br />

How do I start programming a Visual Basic Add-In? I tried the following:
#import "C:\\Program Files\\Microsoft Visual Basic\\VB98\\VB6EXT.OLB"
The compiler failed when it tried to define the 'CommandBarsPtr' type.
Any ideas?
Thanks in advance

Greetings,
I am trying to get the length of the avi source file, and to play it in the time line at that length,
but for some reason I am always getting a "0" returned for the media length. Any suggestions on how
