Hello guys,
I am trying to play with a List control (report style) and I would like to do the following thing :
I select a row in my list (that becomes highlighted) and, thanks to 2 buttons (UP and Down), I exchange the place of this raw with the previous one (UP) to make it go to the top of the list or with the next one (DOWN) to make it go to the bottom of the list.
After a click on one of my buttons, I exchange the 2 rows, my row is no more highlighted and I would like it to keep highlighted. I have tried to play with the SetItemState to set the focus and the selection bits to make it highlighted again but without success.
So my question is : how do I give my row this selected aspect (highlight) by program?
Thanks in advance

m_List.SetItemState(index,LVIS_SELECTED, LVIS_SELECTED);
this will do
|
|
|
|

hello,
that's exactly what I tried (except if my memory fails), LVIS_SELECTED as value and as mask ... I also tried LVIS_FOCUSED ... but without success.
I will doublecheck tonite.
This should immediatly highlight the item, no need of redraw or something else ?
Thanks for the answer

Have you tried LVS_SHOWSELALWAYS Style? It always show the selection, even if the control does not have the focus.
Use SetExtendedStyle() to set the LVS_SHOWSELALWAYS.

good idea !!
it is true that the list lost control because I clicked the button ...
Thanks for answer

Strange .. it doesn't work.
In fact, if I add the LVS_SHOWSELALWAYS option, the control works as if there was a hot item, the fact to keep the mouse pointer over an item selects it, but as soon as I click my buttons, the highlight desappears ...
Very strange ...
Could it be a kind of icompatibility with another option?
I also use : LVS_EX_CHECKBOXES, LVS_EX_FULLROWSELECT, LVS_EX_GRIDLINES, LVS_EX_INFOTIP, LVS_REPORT
I really don't understand what happens ..
Thanks in advance for help

hi,
I ve got some C++ classes that I d like to share with some guys. I d like to make a help file, with a hierarchy chart, the class members, a search engine and so on.. Actually, exactly like MSDN with the MFC. However, I m not familiar at all with this. So here is the question:
Could anybody give me tips about how to make this kind of things (language, soft,and so on)?
cheers

Check out doxygen[^]. There's a online manual[^] for it too.
This will also create a HTML Help project that you can run though the HTML Help compiler and generate a Windows HTML Help .chm file.

Hi,
Use HTML Help Workshop for VC++. Hope this will help u. Gives the same look and feel as that of MSDN.

If you are referring to the little app that comes with the HTML Help compiler and friends, and that organizes things into a crude sort of project, then you're quite mistaken. The only thing that makes it like MSDN is the fact that it outputs the help into a single .CHM file. Doc book outputs a .hhp and .hhk files for use in the HTML Help compiler or even the workshop if you want.

Hi,
I am learning VC++ with some experience with C++, I could compile and execute some simple programs like finding a prime etc successfully. Now I am trying to learn creating a new window using MFC. Whenever I execute the code, i get the following message"
"Hello.exe has encounetered a problem and needs to close..please tell Microsoft about the problem...."
The appname and modname in the technical data are both Hello.exe.
When I click on the Debug button in this window it gives me the following message
"The instruction at "Ox0045c8fb" referenced memorry at "0x00000000". The memory could not be "read". Clik ok to terminate the program."
In the Debug information I have:

The code I am trying to execute is:
// Creating a Hello.cpp win 32 application.
#include <afxwin.h>
class C_MyApp:public CWinApp
{
BOOL InitInstance();
};
class C_MainFrame:public CFrameWnd
{
public: C_MainFrame();
};
C_MainFrame::C_MainFrame()
{
Create(NULL,"Main Window");
}
BOOL C_MyApp::InitInstance()
{
m_pMainWnd=new C_MainFrame();
m_pMainWnd->ShowWindow(m_nCmdShow);
return TRUE;
}
void main()
{
//int m_pCmdShow;
C_MyApp myApp;
}
Can anyone help me on how to successfully execute this program?
Thanks in Advance,

In the following source code fragment a metafile is generated with a line with a length of 60 millimeter using GDI+. The problem is when I analyse this metafile with Visio or print 1:1 on paper, the dimension of the line is not 60 mm ! I hope somebody can tell me the reason.
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
Metafile* myMetafile = new Metafile(L"MyDiskFile.emf", ::GetDC(NULL));
Graphics* myGraphics = new Graphics(myMetafile);
Pen* myPen = new Pen(Color(255, 0, 0, 200));
myGraphics->SetPageUnit(UnitMillimeter);
myGraphics->DrawLine(myPen, 0, 0, 60, 0);
delete myGraphics;
delete myPen;
delete myMetafile;
GdiplusShutdown(gdiplusToken);

Try ShellExecute using the full path to the file selected.
This will open the file using the default application for .txt files, probably notepad.

ShellExecute(hWnd,"open",

There is no spoon.

Hi,
If I create an activeX component using the visual c++ that comes with vs.net 2003 - Is it possible for a client to download this component and use it without having to download the whole .net framework??
|
|
|
|
|
The simple Answer is YES.
ActiveX created by Visual C++ present in vs.net 2003 doesnot use CLR by default. So, no need of .NET framework.

I am currently using Directshow and VC++ to create a simple movie player. I use IGraphBuilder and IMediaEvent interface to render the file (using IGraphBuilder::RenderFile followed by IMediaEvent::Run). When the user selects another movie, I first remove all the filters in the graph (using IGraphBuilder::RemoveFilter) and load the new movie as before. The problem is, there seems to be a memory leak somewhere in my app, since everytime the user selects a new movie, my app's memory usage (seen from Windows Task Manager) always rises by around 1MB and stays there.
Could someone tell me what the possible causes for this leak is? Or does someone know a good sample on this topic?
Thanks!

I want to receive the data from a videoport!

but after I call g_pVPE->startVideo(&ddvpi),
hRet==DDERR_INVALIDPARAMS.
That is I set some parameters wrong!
The setting of parameters are as follows,please help me find the error!
thanks!
int g_CropTop=0x3;
int g_CropLeft=0x1d;
#define CAPWIDTH 800//620
#define CAPHEIGHT 600//440
int g_SurfWidth = CAPWIDTH/2;//310;
// NOTE: g_SurfHeight has to start from CAPHEIGHT/2,
// because of interlace data
int g_SurfHeight = CAPHEIGHT/2;//220;

Hi, I'm a beginner of Visual C++.
And I have a problem in my project, please help me.
In my project,there is a Static text named IDC_STATICTIME,
I put a timer clock on it.And I want to use OnCtlColor function to change the background of the Static text.
Here is the code :
HBRUSH CCallDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CBitmapDialog::OnCtlColor(pDC, pWnd, nCtlColor);
pDC->SetBkMode(TRANSPARENT);
//pDC->SetBkColor(TRANSPARENT);
if (pWnd->GetDlgCtrlID() == IDC_STATICTIME)
{
pDC->SetTextColor(RGB(0, 0, 255));
pDC->SetBkMode(TRANSPARENT);
}
return hbr;
}
But when I compile, it changed only the Text color.
What will I do to change BkMode of the static?
Thank you very much.
King of Merit
