I am using this code to select a listview item. i specify the postion of item using (WPARAM)2 . So this one supposed to highlight and selct the postion 2 in the listview. But unfortuently it does not select but it does deselct. I mean if the item is selected by mouse click it can deselect it but can not select it. Could any one tell me what i am doing wrong here.Thanks
SendMessage(listview, LVM_SETITEMSTATE, (WPARAM)2, (LPARAM)_lvi);
void CSelectuserDlg::OnButton1() <br />
{<br />
<br />
HWND listview=NULL;
HWND parent,child; <br />
parent=NULL; <br />
child=NULL; <br />
parent = ::FindWindow("My Window Class",NULL); <br />
<br />
child =::FindWindowEx(parent,0,"WTL_SplitterWindow",NULL); <br />
child =::FindWindowEx(child,0,"WTL_SplitterWindow",NULL); <br />
child =::FindWindowEx(child,0,"WTL_SplitterWindow",NULL); <br />
child =::FindWindowEx(child,0,"ATL:0053C8D0",NULL); <br />
listview=::FindWindowEx(child,0,"SysListView32",NULL); <br />
<br />
LVITEM lvi, *_lvi; <br />
unsigned long pid; <br />
HANDLE process; <br />
<br />
GetWindowThreadProcessId(listview, &pid); <br />
process=OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE|PROCESS_QUERY_INFORMATION, FALSE, pid); <br />
<br />
<br />
_lvi=(LVITEM*)VirtualAllocEx(process, NULL, sizeof(LVITEM), MEM_COMMIT, PAGE_READWRITE); <br />
lvi.mask = LVIF_STATE; <br />
lvi.state = true; <br />
lvi.stateMask = LVIS_SELECTED; <br />
<br />
WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL); <br />
::SendMessage(listview, LVM_SETITEMSTATE, (WPARAM)2, (LPARAM)_lvi); <br />
VirtualFreeEx(process, _lvi, 0, MEM_RELEASE);<br />
<br />

Hey, I just came across this strange prototype.
This is really weird.
void comm_perror(int error, char *format, ...)
Does anyone have a clue to what the ... parameter is suppose to mean.
This is actually a real function in one of the source codes I was reviewing
If anyone has an answer to this question please keep me posted
Cheers,
Jay

So, do you want to tell us which problems?
If all you want is sin, then just use math.h

In Math libarary there only function like cos,sin,tan... if you like more math function... you might try matlabs or boost library

Any chance any one has an sample project where data from a CListCtrl
is stored and retrieved? I just cant get my own sample project to
work correctly and if I could see something work, then I could try
to mimic those features in my own program.
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

Hi Fellows
I've created an app that reads mp3 sounds. It works fine. I have a idea: I would like to set the volume of the music that is played. I don't have any idea about what interface I must to use or property or anything else.
To play my mp3 sounds I have these interfaces:
IGraphBuilder, IMediaControl, IMediaEvent, IMediaPosition.
I create the IGraphBuilder like this:
<br />
HRESULT hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC, IID_IGraphBuilder, (void**)&g_pMediaGraph);<br />
And the other interfaces like this
<br />
g_pMediaGraph->QueryInterface(IID_IMediaControl, (void**)&g_pMediaControl); g_pMediaGraph->QueryInterface(IID_IMediaEvent, (void**)&g_pMediaEvent); g_pMediaGraph->QueryInterface(IID_IMediaPosition, (void**)&g_pMediaPosition); g_pMediaGraph->RenderFile(wstrFileName, NULL);<br />
Where g_MediaGraph is my IgraphBuilder interface.
Do I need to use another interface instead any of these? If anyone knows a good resource, answer me.

Hi all. i am using this code to change color of listview item.
But unfortunetly it goes and changes color of all item instead
of only changing the color selected listview item. Could an expert
look at this and show me how i can only change color of selected
listview item instead of coloring all items in listview.Thanks
void CColor1Dlg::OnButton1() <br />

<br />
spilterwindow = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
<br />
HWND ATL = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
<br />

That code looks like an absolute nightmare...
I think that in order to do what you want you would need to have to do custom draw for your list view.

could u help me how to make a code that custom draw for my list view.
I am not very expert in visual c++ so i be happy if u show how this can be done. Furthermore, why u say the code i a nightmare!! it does not crash any thing!!! it just does more then what i wanted it to do!

When it comes to doing anything out of the ordinary with a list control then Mike Dunn's article[^] is a must read.

For a limited user on Windows XP, will regsvr32.exe be able to register a namespace extension? I tried and got error 0x80040201, but I'm not sure if this is an issue to do with the account being a limited user or not.
Any help would be greatly appreciated.
Thanks in advance!

Hello,
I have some problems with the PlotXY functions in the NTGraph activeX, Here is the article about this ActiveX:
http://www.codeproject.com/miscctrl/ntgraph_activex.asp[^]
I'll upload for you the picture of the problem here:
http://img433.imageshack.us/img433/4972/untitled2ee.jpg[^]
the function I wrote there the code is: BOOL CGraphsXYAxisDlg::OnInitDialog()(This is the function in the general Dialog)
I sure the problem is there because when I earase the line it works fine.
I tried a few combinations of the point(x,y) but it doesn't work and the errer occurs.
Do you know how can I fix it?
Thank you all for your great help!

Incidentally the correct place to post these questions would actually be at the relevant article[^] itself.
The error message says Element not found. Do you actually have 3 elements for your graph? (ie. did you add 2 extra elements as the 1st was created automatically)
