Hello,
I'm trying to develope a software to capture video from a webcam and sending it through internet.
The primary need is to view through the camera in my building, through the internet, from somewhere else.
I have the knowledge about how to program using CSocket in VC++.
Can any body tell me how to achieve this, please?
Or can you suggest any helpful link or something else?
Thank you.

I have a list view which needs to be sorted based on a click on header.I am using the ListCtrl.SortItems() function. But it is crashing when i clicked on the header.For better understanding i have listed the code.
void CDirTreeDemoView::OnColumnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*) pNMHDR;
this->GetListCtrl().SortItems (CompareFunc, pNMListView->iSubItem);
*pResult = 0;
}
int CALLBACK CDirTreeDemoView::CompareFunc (LPARAM lParam1, LPARAM lParam2,LPARAM lParamSort)
{
ITEMINFO* pItem1 = (ITEMINFO*) lParam1;
ITEMINFO* pItem2 = (ITEMINFO*) lParam2;
int nResult = 0;
switch (lParamSort) {
case 0: // File name
nResult = pItem1->strFileName.CompareNoCase (pItem2->strFileName);
break;
case 1: // File size
nResult = pItem1->nFileSizeLow - pItem2->nFileSizeLow;
break;
case 2: // Date and time
nResult = ::CompareFileTime (&pItem1->ftLastWriteTime,
&pItem2->ftLastWriteTime);
break;
}
return nResult;
}
When i debuged lParam1 and lParam2 are getting value as '0'.
Any hekp please
Thanks

When populating the list, are you also calling SetItemData()?

I am automating MS-Word from my MFC application. My application can get the number of characters currently in the document, the number of sentences, praragraphs e.t.c. For these statistics, various functions are exposed by the Word Automation interface like GetCharCount(), GetWordCount() e.t.c
I want to find out that how many characters in the document are in bold and how many characters are in italics. Is there any way to calculate these values ?? What i am thinking is to iterate each character, but i also donn't know that how can we iterate each character of the document.

I don't know about the automation part, but in MS Word you can search with wildcards and format, so if you can automate that, instead of iterating through each character you could specify a search for [*, use wildcards, bold] and repeat the search counting the hits.

I am in the mist of editing a legacy program which output the report to words format. I am require to add in images, but I am unable to set the position of the images. I am able to add the images but all at (0,0) range.
i'm using the following codes
_Document oDoc;
Shapes oShape;
oShape = oDoc.GetShapes();
oShape.AddPicture
// v is suppose to be the indicator of the top and left points
tagVARIANT v;
v.lVal = v.intVal = v.iVal = v.fltVal = 200;
("C:\\Logo.JPG",vtFalse,vtTrue,&v,&v,vtOptional,vtOptional,vtOptional);
the image still appear at point (0,0)
Is it correct to use Shapes class or should I use InlineShapes 
can someone please advise me... where have I gone wrong

tagVariant is an union. That means all lVal, intVal, iVal, etc. share the same space, so assigning multiple fields makes no sense. You should assign only one of the value fields, and set the vt member to indicate which is the one you are using. As you didn't initialize vt, it must have remained as zero, which indicates an empty variant (i.e.: v.vt == VT_EMPTY), and that may be why the image remains at 0,0
Try the following:
tagVariant v;
v.vt = VT_I4;
v.lVal = 200;

problem for position solved but I encounter another problem, i need to put the images into different cells in a table and some images are to be outside the table. The codes is able to work but all the images are inserted into the first cell in the first table. Is there a way to set the position with respect to the a cell?

Using VC6 on Win2k...
I have a test app with the following characteristics:
- Dialog-base app with MFC dynamically linked
- Dialog has no titlebar, but it does have a thin border.
- There is a single static bitmap control on the dialog
- I created a CStatic-derived class to allow it to draw a DIB on the dialog using Chris Maunder's CDIBSectionLite class
- I put the derived control inside the AFX_DATA macros of the dialog
- there is no dynamic allocation going on in my app
When I shut a test app down, I get the following in the output window:
The thread 0x394 has exited with code 27 (0x1B).
The program 'K:\TEST APPS\bmploader\Debug\bmploader.exe' has exited with code 27 (0x1B).
Does anyone know why, and how to clean this up?

Is there only one thread ? You're just getting this in the UI ? Are you sure it means anything important ? I doubt it does.

I think it means you closed the dialog with the Esc key (scan code of Esc is 0x1B = 27).

These messages only appear in the output window in the IDE. Unless you need to use the app's exit code for something else, I wouldn't worry about it.

That's probably it. I don't have any buttons on the dialog box, so I have to press escape to get out of it.

When you shut down the application using Alt+F4 instead, notice that the thread exists with a code of 2, which is Cancel/Close. What you are seeing is normal.

Maybe this note in the help for Edit Control Styles[^] can help:
ES_PASSWORD
Displays an asterisk (*) for each character typed into the edit control.
This style is valid only for single-line edit controls.
Windows XP: If the edit control is from user32.dll, the default password character is an asterisk. However, if the edit control is from comctl32.dll version 6, the default character is a black circle.
To change the characters that is displayed, or set or clear this style, use the EM_SETPASSWORDCHAR message.

thanks for you reply.
Maybe there's some misunderstanding.I set single line editbox style to ES_PASSWORD,then it should show asterisk(*) or black circle (.). but in mozila
and firefox explore on windows XP,It shows "|",don't you think it is unexpectable?
what cause this happen? do mozila and firefox not match XP platform well?

I don't know. But you may test the dialog outside of the browser to see if it's a problem that only occurs inside the browser or not.
You may also try explicitly setting the password char and see if that helps or not in your case.

Folks here is another one,
I do all operations on bitmaps within .NET DLL project, while the DLL is being used by a C++ project(windows project to be exact). When I perform operations on bitmaps I have to pass locations of them from C++ project to .DLL.
BSTR bla(L"C:\\temp\\TestDLL1.bmp_BGL.bmp");
BSTR bla1(L"C:\\temp\\TestDLL1.bmp_GDI.bmp");
HRESULT hr = myobject->Load2BitmapsfromFile(bla, bla1, 50, &m);
Vb.NET DLL project is set to recieve these path locations as parameters and based on them create bitmaps and more.
The problem raises when I run my C++ project and debug to realize that the strings used to pass bitmap locations to .DLL are now empty. Thus I got nothing useful from that method in DLL.
Any commnets on this would be helpful.
Thank you,
Sincerely,
Max Pastchenko

Why are you being so cruel to C++, to make it talk to VB ? :P
Seriously though, what's the reason for this ? You can write GDI+ code in C++, you don't need .NET at all.

The strings are constants and they are empty ? Or are you not looking at them properly ? Can the IDE show the contents of a BSTR ? If they are constants, they simply cannot be empty, as far as I can see. Why not debug the dll and see what ends up in VB.NET ? Or just put in a log file or something.

In instead of having next programmer, work with GDI+ and put that constraint on him (this is a only a part of the project that will be used by someone else), I would rather contain all GDI+ in .NET thats why I am using paths (strings). So its easier for someone else, especially if not familiar with GDI+ directly to just say:
LoadANDCompareMaps(bstingpath1, bstringpath2, etc)
The solution to my priblem is quite simple:
I was declaring my binary strings incorrectly
correct syntax:
BSTR bla = SysAllocString(L"C:\\temp\\TestDLL3.bmp_BGL.bmp");
Thank you
Sincerely,
Max Pastchenko
P.S. I debugged on VB side with C++ executable and thats how I found that they were empty. And as far as i see C++ is talking to a .NET DLL which is created by VB.NET
